you can use place_forget iirc. I'm not sure though because I usually just stick to grid and pack, but since there are grid_forget and pack_forget methods, it should be the same in theory

Can someone help me find out what the issue with my program is here?

#

When I run this program (https://paste.pythondiscord.com/ubuhuhelav.py) alone, it runs and executes all its functions correctly.

#

However, it's supposed to be run as a module of a main program, and it doesn't work when 'Add Subject' is clicked from this UI: https://paste.pythondiscord.com/vokepewoqi.py

#

It does give some error about ui not being defined or something, but I'm not sure why.

sudden coral Mar 23, 2019, 9:36 PM

#

I think you need to do self. instead of ui.

#

at line 66

wispy oar Mar 23, 2019, 9:49 PM

#

I tried that, it still gives me the same error.

#

Error refers to line 200 in my_subjects, then line 21 in my_subjects, then line 62 in add_subject.

#

NameError: name 'ui' is not defined

sudden coral Mar 23, 2019, 9:52 PM

#

It's a similar issue on line 62

#

use self. rather than ui.

wispy oar Mar 23, 2019, 9:54 PM

#

That solved the issue, thank you. I'm not sure why I didn't use self. in the first place.

wispy oar Mar 23, 2019, 11:42 PM

#

How would you suggest that I go about automatically updating a list whenever a subject is added/removed? https://paste.pythondiscord.com/vokepewoqi.py

#

I was thinking of using JSON, but not sure about the implementation. I'd probably have to change the way subjects are displayed (I currently have separate labels).

sudden coral Mar 23, 2019, 11:48 PM

#

You could use JSON but I think it'd require a fair bit of manual work to get it going

#

Like you could use a QListView which uses custom implementation of a QAbtsractItemModel that has a JSON file as a back end.

#

You could go with a database instead which can provide a model for you, but then you have more complexity added in having to set up the database

#

Interestingly, something like this has already been done with JSON https://wiki.qt.io/JSONListModel

JSONListModel

#

but it's for QML...

#

Oh hey maybe you can use this https://doc.qt.io/Qt-5/qstringlistmodel.html

alright, i'm taking intro to cs so not that complex stuff, I need to create a method that i can call so i prints out a rectangle where i click. I want to do this by doing drawRect but when i try to include this into another class and call it into my paintEvent it says it isn't defined

onyx sky Mar 25, 2019, 3:44 PM

you're saying method, so it's a method on a class right?

You could post code snippets in here of the two classes and where you try to call it. Use ``` before and after and on the line with the first ` `` include py

i try calling it in that if statement

onyx sky Mar 25, 2019, 3:53 PM

Unless i'm misreading somethying, it looks like qp is a QPainter object, not a rectangle object which is what the method is on?

uncut crystal Mar 25, 2019, 3:55 PM

can't i use that qp object and call the drawrectangle?

not if drawrectangle() isn't a method of qp.

is there a way to create a method that would allow me to call it onto the qp from a different class in a different file

onyx sky Mar 25, 2019, 3:57 PM

onyx sky Mar 25, 2019, 3:58 PM

(although, idk. maybe not assigning the class to a variable is bad practice? I would need input from someone more experienced. If it is just do rect = rectangle() \n rect.drawrectangle()

uncut crystal Mar 25, 2019, 3:59 PM

hmm that's why i thought i would have to call a method that would let me draw the rectangle

im not sure what you mean, sorry. I'm not that experienced either. Mb someone else can help?

All i know is drawrectangle is a method of rectangle. You have to call it from an instance of rectangle.

@sudden coral Hi, sorry that I haven't been able to get back to your feedback for a while.

#

I did look into QStringList a bit, but I'm a bit lost about the implementation.

#

I currently have the user's subjects displayed like this: https://i.imgur.com/ZBjqWZH.png

Imgur

sudden coral Mar 25, 2019, 4:57 PM

#

The reason I suggested the QStringListModel is because you should use a QListView to display the subjects.

#

However, those View Details buttons are a little problematic since it'd probably be a hack to try to include them in the QListView as well. So may I suggest a design change?

wispy oar Mar 25, 2019, 4:59 PM

#

Yeah sure. To be honest, I might not even end up having the option to view details because I'm running a bit low on my coursework deadline, but I'd happily take some input.

sudden coral Mar 25, 2019, 5:00 PM

#

You could

Add a context menu (the menu when right clicking) and put a "view details" action in that menu.
View details when double clicking an item in the list view.
Have a single button which shows the details for whichever item is selected/highlighted in the view.

wispy oar Mar 25, 2019, 5:01 PM

#

Ah yeah, #2 seems like a great solution there actually.

sudden coral Mar 25, 2019, 5:04 PM

#

Regarding the model. You can read the JSON and get all the subjects as a list. Then you can set the internal list of the QStringListModel with .setStringList()

#

Because the model will be attached to the view, the view will automatically refresh when the model is updated

wispy oar Mar 25, 2019, 5:05 PM

#

So currently as it stands, my program will assign the user's new subject string as a variable for temporary storage.

#

To save it as a list, I'd just have to append this string to the JSON file?

sudden coral Mar 25, 2019, 5:06 PM

#

The JSON file itself is not connected to anything. To update the model, you'd need to re-read the JSON file.

#

However, I think it's fine to just append to the model's internal list and write the JSON file - no need to re-read after

#

Thus the JSON file is only used to persist the data i.e. make sure data is still there when program exits

#

Then you could also approach this by only saving the JSON file when the program closes.

#

You'd just get the list from the model and write that to JSON

#

But I don't know how reliable that'd be if say the program encounters and error and crashes

wispy oar Mar 25, 2019, 5:09 PM

#

Yeah, that's a good consideration.

#

Thank you. What would the difference be between using a list view and a list widget? I'm looking at these two now in Qt Creator, and I don't see an obvious way of using the list view.

sudden coral Mar 25, 2019, 5:10 PM

#

I am not very familiar with the corresponding "widget" versions of controls

#

I think it's just an older way of doing the same thing, but also offers less customisation

#

Like it doesn't use the model/view paradigm

#

It will look barren in the Designer. You'll need to write code to actually make the view do stuff.

wispy oar Mar 25, 2019, 5:13 PM

#

If my use case is limited to perhaps ordering these items alphabetically ascending, and then using these items for a combo box (dropdown menu), would I be better off using the widget? It seems like an easier implementation if it meets my needs.

sudden coral Mar 25, 2019, 5:14 PM

#

How is data populated for widgets?

wispy oar Mar 25, 2019, 5:14 PM

#

My plan was that this list would be used for a dropdown menu when adding a new task like this: https://i.imgur.com/yH5GhMR.png

Imgur

sudden coral Mar 25, 2019, 5:15 PM

#

So you need to display the subjects in two different places?

wispy oar Mar 25, 2019, 5:16 PM

#

Not sure how data is populated for widgets entirely to be honest, I'm not too knowledgeable in this, working on this as a coursework project.

#

When I check in Qt Creator, it looks like this: https://i.imgur.com/7A9073m.png

Imgur

#

The idea was that the list of subjects would basically enable the user to customise the options in the dropdown menu, because it would be easier for them to select from options than repetitively typing in 'Computer Science' for 10 tasks.

sudden coral Mar 25, 2019, 5:16 PM

#

Right, but that's not very useful to you since the data is meant to be added by the user anyway, right?

wispy oar Mar 25, 2019, 5:17 PM

#

Yeah.

#

I did find some code for it, one moment.

#

https://wiki.python.org/moin/PyQt/Adding items to a list widget

sudden coral Mar 25, 2019, 5:17 PM

#

Simple enough.

#

But, if you need the subjects displayed on two different controls then a model makes even more sense to me

#

otherwise you're doing code like that for two different controls

wispy oar Mar 25, 2019, 5:19 PM

#

Wouldn't it be a case of the items being sorted from the list in my_subjects.py, then add_task.py reading that list for the combo box?

sudden coral Mar 25, 2019, 5:20 PM

#

Yeah, sure.

#

I just find it to be a kinda convoluted. More work than you really need to do to accomplish it

#

But if you find that approach more comfortable then go for it

#

I like my models and views 🙂

wispy oar Mar 25, 2019, 5:22 PM

#

It might just be that I don't really understand either of them in too much detail. My knowledge with PyQt5 is limited to creating the user interfaces, and some basic functionality for them.

#

Could you explain the difference between model-based and item-based, and how they would work?

sudden coral Mar 25, 2019, 5:23 PM

#

This goes into great detail what models and views are https://doc.qt.io/qt-5/model-view-programming.html#using-models-and-views

#

Don't be scared off by the length though

#

It goes into far more detail than you need to know right now

#

Just try reading the introduction

wispy oar Mar 25, 2019, 5:26 PM

#

Okay thank you. As a side note, does everything in that Qt Documentation apply to PyQt5 as well, or is it just some select parts?

sudden coral Mar 25, 2019, 5:27 PM

#

I think both PyQt5 and PySide2 (Qt for Python) strive to be 1 to 1 wrappers of the C++ version of Qt

#

I've used the C++ docs before and it's fine

#

They also have PySide2 docs on the same site but it's just faster to search without having to always add "qt for python" at the end

#

And the PySide2 docs feel a bit less complete in some places, though the examples are in Python rather than C++ so that's useful

wispy oar Mar 25, 2019, 5:29 PM

#

Ah, I see. Well, I'll have a read up and see how far I can get. Thank you for the help and explanations.

I tried changing the alpha value on the palette, but it seemed to go back to 255, so maybe I'm doing something wrong?

sudden coral Mar 25, 2019, 10:00 PM

#

Try using stylesheets

#

Not very familiar with them myself but it's similar to CSS

#

You probably want https://doc.qt.io/qt-5/stylesheet-reference.html#background-color-prop

wispy oar Mar 25, 2019, 10:07 PM

#

Using self.list_widget_my_subjects.setStyleSheet("background-color: rgba(0, 0, 0, 0);") worked, thanks.

sudden coral Mar 25, 2019, 10:42 PM

#

If you prefer I am pretty sure you can specify the stylesheet in the designer too

wispy oar Mar 25, 2019, 10:47 PM

#

Yeah I looked for that afterwards in case I wanted to make other changes later on.

#

It's a bit weird though, if you set the colour, it types the 'rgba...' part for you, but not the background-color, so it isn't valid until you type that in yourself.

wispy oar Mar 25, 2019, 11:24 PM

#

@sudden coral How would you suggest I display the list of subjects? I have add_subject.py updated, so now it will append the input to a JSON file.

#

I looked at this (https://wiki.python.org/moin/PyQt/Adding items to a list widget) and it seemed like it was for a more specific purpose.

#

I know I can use .addItem(item), but how would I get each item from the JSON file individually? Would I have to convert the JSON back to a tuple first, then perform iterations?

#

The function I added is: # Saves input as JSON and appends it to the JSON file for the list of subjects. def save_subject(self): new_subject_name = self.line_edit_subject_name.text() print(new_subject_name) new_subject_name = json.dumps(new_subject_name) with open('subject_list.json', 'a') as f: json.dump(new_subject_name, f)

sudden coral Mar 25, 2019, 11:28 PM

#

Uh, does that even give you a properly format JSON doc?

#

I believe you need to read the JSON, add to the dictionary/list you get

#

then dump the entire thing again

#

You can keep the dict/list in memory and then just keep dumping that so you dont need to re-read every time

wispy oar Mar 25, 2019, 11:32 PM

#

It gives me this, which I think is fine? https://i.imgur.com/BZNHnnf.png

Imgur

sudden coral Mar 25, 2019, 11:32 PM

#

No, that's not correct

#

You might as well just use plain text file at that point

wispy oar Mar 25, 2019, 11:35 PM

#

How is the JSON file supposed to be formatted? I've only previously worked with using it on W3Schools (https://www.w3schools.com/python/python_json.asp). I was thinking of using plain text files, but I figured that JSON is the standard used for a reason; maybe it would be better to use plain text files as this is quite a simple use case?

sudden coral Mar 25, 2019, 11:49 PM

#

Yeah plain text sounds better

#

you're only storing one thing per line so json doesnt give you any benefits

wispy oar Mar 25, 2019, 11:53 PM

#

I double checked again, and I was missing the attributes for the values in the JSON file, right?

#

So it would have like an attribute title, followed by 'Computer Science'?

#

I was then thinking that JSON might be something which would be more appropriate for storing the actual tasks, which would include the task title, subject, and due date.

sudden coral Mar 25, 2019, 11:54 PM

#

Not necessarily. An array can be the top level item in JSON too

#

What you're describing is a dictionary (known as an object in JSON technically)

wispy oar Mar 25, 2019, 11:55 PM

#

So what is the use case for JSON over plain text?

sudden coral Mar 25, 2019, 11:56 PM

#

When you need to store data in a more orgasnised manner

wispy oar Mar 26, 2019, 12:01 AM

#

Do you think it would be most appropriate to store the subject list as plain text, and the list of tasks (and their details) as JSON?

sudden coral Mar 26, 2019, 12:02 AM

#

Yeah that sounds ok

#

You could still use JSON for both

#

maybe just to be more consistent

#

up to you

wispy oar Mar 27, 2019, 12:48 AM

#

@sudden coral So I've coded my_subjects.py and add_subject.py to use subject_list.txt and the QListWidget, but I'm not sure how to refresh the QListWidget after I've added a subject.

#

So basically, if I had a list with Comp Sci, Further Maths, Maths, then I used the dialog to add 'History', the list won't update afterwards.

#

I currently have: class Ui_mwindow_my_subjects(object): # Setting up the widgets of My Subjects. def setupUi(self, mwindow_my_subjects):

#

...

#

            subject_list = data_file.readlines()
            print(subject_list)
            print(len(subject_list))
            for line in subject_list:
                self.list_widget_my_subjects.addItem(line.replace("\n", ""))```

#

And this works, but only for the state of the .txt file when the main window is opened, not for the updated state after I've added a new subject.

#

I did do some research, and found the command QWidget.update(), but how would I implement that into my_subjects.py so it can detect when the add_subject.py dialog has been closed?

It seems you have to provide a variable when making the radio button.

wet canopy Mar 27, 2019, 1:19 AM

Because I have a quiz and its setup like so.

You can use `` with the code in between them to show the code.

That's not a radio button.
Could you maybe copy and paste the code instead to make it more readable?

By directly putting .grid behind the creation of the combo box, you aren't saving it to a variable.

#

cmb = Combobox()
cmb.grid()```

    cmb4 = ttk.Combobox(test, values=['A: Pete Rose', 'B: Rogers Hornsby', 'C: Joe DiMaggio', 'D: Ty Cobb']).grid(row=8, column=0)

    cmb5 = ttk.Combobox(test, values=['A: Michael Jordan', 'B: Wilt Chamberlain', 'C: Kobe Bryant', 'D: Kareem Abdul-Jabbar']).grid(row=10, column=0)

    btn1 = Radiobutton(test, text='Finish', indicatoron=0, pady=3, fg='RED', bd=2, command=quizanswer).grid(row=11, column=0)
    btn2 = Radiobutton(test, text='Quit', indicatoron=0, pady=3, fg='RED', bd=2, command=test.destroy).grid(row=11, column=1)

    mainloop()

    return cmb1, cmb2, cmb3, cmb4, cmb5, correct

def quizanswer():

    if cmb1.get() == 'A: Pittsburgh Steelers':
        correct.append(1)

    else:
        correct.append(0)

#

thats as much as I could fit

#

I used cmb1, cmb2 e.t.c

desert sapphire Mar 27, 2019, 1:24 AM

#

    cmb3 = ttk.Combobox(test, values=['A: Los Angeles', 'B: Indianapolis', 'C: Miami', 'D: Austin']).grid(row=6, column=0)```
This doesn't set cmb3 to the combobox. It sets it to the result of .grid(), which is None

wet canopy Mar 27, 2019, 1:25 AM

#

Oh, because I used .grid at the end of my other buttons and they work fine. But this one if giving me the NoneType error.

Those will also be None, you just don't use those.

Ok ill try to redo it

#

Thank you for the help

wispy oar Mar 27, 2019, 1:28 AM

#

Does anyone know how I could refresh my main window (or just the QListWidget inside of that main window) when a dialog is closed?

#

I have a main window for a list of subjects, and a dialog to add new subjects. The QListWidget displays the list correctly at first, but it doesn't update itself when a subject is added, and I'm not sure how I could do this. https://i.imgur.com/pC21dcO.png

Imgur

sudden coral Mar 27, 2019, 1:32 AM

#

@wispy oar QWidget.update() is not useful here at all. The add_subject dialogue is opened via the my_subjects window. This means my_subjects should have a variable containing the instance of the add_subject class. Once you know the dialogue closes, you can access the instance of add_subject from my_subjects and retrieve the subjects that were entered. Then you can append them to the list in my_subjects and update the JSON file.

wispy oar Mar 27, 2019, 1:34 AM

#

So, currently I have my dialog set up to open like this: ```

Connecting the button to the setup of the dialog for adding a new subject.

def open_dialog_add_subject(self):
    self.Dialog = AddSubjectDialog()
    self.Dialog.show()```

sudden coral Mar 27, 2019, 1:34 AM

#

I may take that back on the update() I don't actually know the listwidget is updated

#

I assume addItem automatically updates it

wispy oar Mar 27, 2019, 1:35 AM

#

addItem adds the items at the start, but it's kind of like a one-time thing.

#

The whole programs currently look like this:

#

https://paste.pythondiscord.com/fowirubojo.py

#

https://paste.pythondiscord.com/ohucivujul.py

#

Lines 304 and 330 in the first file for populating the QListWidget and opening the dialog.

sudden coral Mar 27, 2019, 1:38 AM

#

So you can do self.Dialog.line_edit_subject_name and then get the text inside the line edit

#

From there you can do addItem() as well as writing to JSON or whatever

wispy oar Mar 27, 2019, 1:41 AM

#

Yeah that's what I did on line 86 of the second program (the dialog window), but I need a way of coding the first program to detect when the dialog window is closed.

sudden coral Mar 27, 2019, 1:41 AM

#

How does show() work again, remind me

#

Is it modal or non modal?

wispy oar Mar 27, 2019, 1:41 AM

#

Then I was thinking once it can detect it has been closed, it can repopulate the QListWidget somehow (either by deleting all items then readding, or just refreshing or something).

sudden coral Mar 27, 2019, 1:41 AM

#

So the current issue is you don't know how to detect it closing?

wispy oar Mar 27, 2019, 1:41 AM

#

Uh, I'm not sure what you mean.

#

Yeah.

#

Just looked into it a bit, .show() is non-modal.

sudden coral Mar 27, 2019, 1:43 AM

#

Apparently it depends on a property you set

#

You should use QDialog.open()

#

then you can connect a slot to the QDialog.finished or QDialog.accepted signal

#

And if you don't know what signals and slots are they are basically the event system in Qt

#

It's pretty important to know how to use it I'd say

wispy oar Mar 27, 2019, 1:45 AM

#

In the dialog, my accepted button is currently linked to the function for saving a subject. ``` # Connects 'Save' button to save the user input.
self.button_box_new_subject.accepted.connect(dialog_new_subject.accept)
self.button_box_new_subject.accepted.connect(self.save_subject)

    QtCore.QMetaObject.connectSlotsByName(dialog_new_subject)

def retranslateUi(self, dialog_new_subject):
    _translate = QtCore.QCoreApplication.translate
    dialog_new_subject.setWindowTitle(
        _translate("dialog_new_subject", "Add Subject"))
    self.lbl_new_subject.setText(_translate(
        "dialog_new_subject", "Add a New Subject"))
    self.lbl_subject_name.setText(_translate(
        "dialog_new_subject", "Subject Name:"))

# Permanently saves input to a .txt file for the list of subjects.
def save_subject(self):
    new_subject_name = self.line_edit_subject_name.text()
    print(new_subject_name)
    with open('subject_list.txt', 'a') as outfile:
        outfile.write(new_subject_name + "\n")```

sudden coral Mar 27, 2019, 1:46 AM

#

I see

#

you should make that connection from the main window, not inside the dialogue

#

Otherwise that's basically what I had in mind

wispy oar Mar 27, 2019, 1:47 AM

#

So the function would go in my_subjects, or the function and also the .connect() parts?

sudden coral Mar 27, 2019, 1:47 AM

#

both

wispy oar Mar 27, 2019, 1:47 AM

#

And I'd just put it in here? # Connecting the button to the setup of the dialog for adding a new subject. def open_dialog_add_subject(self): self.Dialog = AddSubjectDialog() self.Dialog.open()

#

Like, at the end?

sudden coral Mar 27, 2019, 1:48 AM

#

Connect the signal before you open the dialogue

wispy oar Mar 27, 2019, 1:49 AM

#

The thing is, if I try to put anything in that function (after .open()), the dialog won't work at all.

sudden coral Mar 27, 2019, 1:50 AM

#

You mean it won't even open?

wispy oar Mar 27, 2019, 1:50 AM

#

It'll open, but not really properly. The widgets in the window won't load, and the program just crashes eventually.

sudden coral Mar 27, 2019, 1:51 AM

#

Maybe cause a parent needs to be set 🤔

Thanks, it could just be the case that I'm misunderstanding you in terms of how I would make the connections in the main window.

sudden coral Mar 27, 2019, 2:00 AM

#

Works fine for me

#

Since I already did it may as well show you exactly what I meant ```py
def open_dialog_add_subject(self):
self.Dialog = AddSubjectDialog()
# Connects 'Save' button to save the user input.
self.Dialog.button_box_new_subject.accepted.connect(self.save_subject)
self.Dialog.open()

# Permanently saves input to a .txt file for the list of subjects.
def save_subject(self):
    new_subject_name = self.Dialog.line_edit_subject_name.text()
    print(new_subject_name)
    with open('subject_list.txt', 'a') as outfile:
        outfile.write(new_subject_name + "\n")```

wispy oar Mar 27, 2019, 2:02 AM

#

Ah, I think it's just because I forgot to move the .open() to the end.

#

Or actually, I just tried it the other way around, still works. Not sure what I did wrong before.

#

Thanks, so now I would add to the end of the save_subject function some code to clear the list, then repopulate it?

sudden coral Mar 27, 2019, 2:05 AM

#

Just addItem should work

wispy oar Mar 27, 2019, 2:07 AM

#

On line 304, I had the lines added one by one by searching through the list.

sudden coral Mar 27, 2019, 2:07 AM

#

What would you need to search for?

#

You already have the subject

wispy oar Mar 27, 2019, 2:07 AM

#

Well, it would go to line 1, add item, line 2, add item, etc.

sudden coral Mar 27, 2019, 2:08 AM

#

Are you thinking you need to read the file again? Cause you don't

#

new_subject_name is the subject to add

#

All you gotta do is pass it to addItem()

#

It will get appended to the end of the list widget

wispy oar Mar 27, 2019, 2:09 AM

#

Oh right, I see, that works now. Thank you.

sudden coral Mar 27, 2019, 2:10 AM

#

By the way, you should keep the auto generated code and your own code in separate files

#

The auto generated code is ugly and bulky

#

You can just subclass the auto generated class like you did with AddSubjectDialog

wispy oar Mar 27, 2019, 2:13 AM

#

Yeah you're right actually, it would make things a lot easier for future development as well. For that function, I had open_dialog_add_subject linked to the click of a button. What would I do to trigger this function automatically when the program is run?

carmine star Mar 27, 2019, 2:13 AM

#

What's the difference between communicate() and stdout.read()?

wispy oar Mar 27, 2019, 2:15 AM

#

Oh, I would just put self.my_subjects_actions() in the class for the main window?

sudden coral Mar 27, 2019, 2:15 AM

#

@wispy oar You can just call that function in showEvent is suppose

#

maybe that event is a bad idea

#

apparently it can receive it spontaneously

#

Maybe the __init__ is a better place

wispy oar Mar 27, 2019, 2:18 AM

#

I was going to put it in class Ui_mwindow_my_subjects(object): when it sets up the widgets?

sudden coral Mar 27, 2019, 2:18 AM

#

I suppose that works but if you're trying to keep auto generated code separate then you'd end up moving it out eventually anyway

wispy oar Mar 27, 2019, 2:18 AM

#

Sorry, I mean the setupUi part.

#

Isn't that how I'd keep it separate? I'd remove all the extra things I added apart from that one line to connect my separate action code?

#

So I'd have:

#

    # Setting up the widgets of My Subjects.
    def setupUi(self, mwindow_my_subjects):```

#

...

#

self.my_subjects_actions()

sudden coral Mar 27, 2019, 2:21 AM

#

No, it's not necessary. It seems you think that it's important to write your code in setupUI but it doesn't matter

#

Let's use the other class as an example, since you already have it ```py
class AddSubjectDialog(QDialog, Ui_dialog_new_subject):
def init(self):
super().init()
self.setupUi(self)
# keep doing whatever you want here...
def some_new_function():
# can add new functions too

wispy oar Mar 27, 2019, 2:24 AM

#

So if I had the separate program my_subjects_actions.py, what code would I need to add to the auto-generated code?

sudden coral Mar 27, 2019, 2:25 AM

#

Nothing

wispy oar Mar 27, 2019, 2:25 AM

#

The AddSubjectDialog class seems like a different use case because it's only triggered in a specific condition, not automatically.

sudden coral Mar 27, 2019, 2:25 AM

#

Maybe if you look at some example programs you'll understand

#

I'll link a project I worked on

#

Here's the generated code

#

I put all modules for generated code in a ui sub-package

#

One difference is that I chose not to subclass, instead assigning it to self.ui

#

This is just preference, you can keep subclassing if you want

#

I didn't touch the auto generated file at all

#

This also makes it very easy to make changes to the UI in the designer and re-generate the file

wispy oar Mar 27, 2019, 2:30 AM

#

So when you want to run the program, you just run it from the program you changed, rather than the auto-generated code?

sudden coral Mar 27, 2019, 2:31 AM

#

yeah

#

My own code calls the setupUi function in the auto-generated class

wispy oar Mar 27, 2019, 2:32 AM

#

Ah okay, I thought you'd have to import the auto-generated code and then run it from that.

#

Oh, you did it by importing it on line 8, right?

sudden coral Mar 27, 2019, 2:33 AM

#

Yeah I am importing it

wispy oar Mar 27, 2019, 2:34 AM

#

Okay I think I understand this better now, I'll just have to see how it goes with my code.

#

The only other thing was how I can make the QListWidget expand vertically rather than scrolling straight away?

#

When I looked at the widget in Qt Creator, I set it to expanding size, but it just acts like it's a fixed size.

#

As in, it currently just scrolls like this: https://i.imgur.com/30ixdWl.png

Imgur

#

But I only want it to scroll when it would otherwise go beyond the window.

#

The properties seem like they would be doing this: https://i.imgur.com/R07bhxv.png

Imgur

#

Seems like if I just resize the vertical layout in the editor, it will fix it, but not sure why the QListWidget won't just fit to size. https://i.imgur.com/lHgI97h.png

Imgur

sudden coral Mar 27, 2019, 3:31 AM

#

I think you have a lot of unnecessary widgets

#

You don't the need scroll area or the qwidget under it

#

And you could probably change the central widget to just be a vertical layout instead of a grid

#

That way you could get rid of the two other layouts you have

vernal mango Mar 27, 2019, 4:34 AM

Anyone know if this is possible with Qt? Or how to go about doing it?

Could someone explain why my QListWidget isn't expanding all the way to the bottom?

#

https://i.imgur.com/FWlPtQV.png

Imgur

#

It appears that my vertical layout size is limiting it somehow, but I don't see why, because the QListWidget is set to 'expanding'.

#

I could fix it by increasing the vertical layout to reach the bottom of the screen, but I don't know what constraint I would be changing, and why it fixes the issue.

I'm not sure to be honest, I'll change that as well.

#

It's just one scroll area, but they are packaged together; one is the QScrollArea, and the other is the QWidget for it.

If you try adding a scroll area, you'll see what I mean.

wispy oar Mar 27, 2019, 10:42 PM

#

It's really strange. Perhaps I should just resize the vertical layout's height and leave it at that?

#

I was also wondering if you could help me a bit with separating my auto-generated code and the code I added to the program.

#

So far, I've just been adding the operational code to the auto-generated program file, but it's not really good practice, so I want to fix that.

#

I have taken out the operational code (the code I added) and put it in another Python file, but I'm not sure what to do with it really.

#

This is my_subjects.py, the code which I originally had (auto-generated code and operational code in the same file): https://paste.pythondiscord.com/domowucufi.py

#

This is the my_subjects_generated, the auto-generated code (with comments added because I need it for coursework documentation): https://paste.pythondiscord.com/erayoqinez.py

#

This is my_subjects_actions.py, the operational code (mostly copied and pasted it from the original program file, but I did try to fit it together somehow, and failed): https://paste.pythondiscord.com/dexutabuso.py

#

I'm not really sure about the structure of how to get the operational code to use the auto-generated code to set up the widgets.

But from what I have in my_subjects_actions.py now, it says

#

#

I don't understand that, because I imported my_subjects_generated (the auto generated code).

sonic bridge Mar 27, 2019, 11:04 PM

This is the problem

import my_subjects_generated

...

class MySubjectsWindow(Ui_mwindow_my_subjects):

#

You are importing my_subjects_generated, not Ui_mwindow_my_subjects

#

You should use

from my_subjects_generated import Ui_mwindow_my_subjects

or

class MySubjectsWindow(my_subjects_generated.Ui_mwindow_my_subjects):

wispy oar Mar 27, 2019, 11:06 PM

#

Ah I see, thank you.

#

So I changed line 16 onwards to: class MySubjectsWindow(my_subjects_generated.Ui_mwindow_my_subjects): def __init__(self): super().__init__() self.setupUi(self)

#

I thought that might work because that's how I originally coded the dialog (which is opened from this main window) to open, but the program just runs, does nothing, and then stops.

sonic bridge Mar 27, 2019, 11:10 PM

#

You are missing something there.
Remember, Ui files are just dummy classes that only know how to set up some widgets, but the class itself is not a proper window/dialog/whatever.
MySubjectsWindows must inherit from QMainWindow (implying its a main window) AND Ui_mwindow_my_subjects.

#

from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QMainWindow

class MySubjectsWindow(QMainWindow, my_subjects_generated.Ui_mwindow_my_subjects):

wispy oar Mar 27, 2019, 11:12 PM

#

That makes more sense, I was a bit confused because the generated code just uses 'object'.

#

I did decide to use the 'from x import y' form instead because it makes the code look cleaner.

sonic bridge Mar 27, 2019, 11:13 PM

#

Yeah, it is expected that the main class will inherit from both.

#

Yeah, I agree, I just forgot.

wispy oar Mar 27, 2019, 11:15 PM

#

Now the main window does load, but it only loads the UI. The operational code to make the UI do things doesn't seem to be loading, so I suspect the issue is with where I've placed those bits of code?

#

This is what I have so far: https://paste.pythondiscord.com/doxakikuja.py

#

I added the if __name__ part at the end, which got the UI elements to load, but I'm not sure if that's redundant when the generated code has that already. I would have thought that the generated code is designed to work without the operational code adding that if __name__ part again?

sonic bridge Mar 27, 2019, 11:18 PM

#

I would suggest to change your entry point code. I dont know how to explain but it is a bit strange to me. I dont get what you tried to do there. This is what I always use

    app = QtWidgets.QApplication(sys.argv)
    mwindow_my_subjects = Ui_mwindow_my_subjects()

    sys.exit(app.exec_())

wispy oar Mar 27, 2019, 11:19 PM

I don't think I changed any of that part, I just used what the generated code gave me at the bottom.

wispy oar Mar 27, 2019, 11:24 PM

#

Yeah, that fixes the issue with the operational code not working. What is the difference between that and the one I used from the generated code?

sonic bridge Mar 27, 2019, 11:25 PM

#

Can you put a snippet with that part of generated code? Just to make sure we are talking about the same thing.

wispy oar Mar 27, 2019, 11:26 PM

#

Yeah sure. ```'''if name == "main":
import sys
app = QtWidgets.QApplication(sys.argv)
mwindow_my_subjects = QtWidgets.QMainWindow()
ui = Ui_mwindow_my_subjects()
ui.setupUi(mwindow_my_subjects)
mwindow_my_subjects.show()
sys.exit(app.exec_())'''

if name == "main":
import sys
app = QtWidgets.QApplication(sys.argv)
mwindow_my_subjects = MySubjectsWindow()
mwindow_my_subjects.show()
sys.exit(app.exec_())```

#

First block is just the part I copied from the end of that generated code.

sonic bridge Mar 27, 2019, 11:37 PM

#

I never got something like that into my generated code, but it doesnt matter. At the end both do the same thing, I think the last one is cleaner tho. Also that is what every tutorial/book suggest.
I guess if you replace QtWidgets.QMainWindow() in the first code with MySubjectsWindow(), you will achieve the same thing as the second one.

It works nows because the operational code is managed by class MySubjectsWindow. Remember that I said that Ui_mwindow_my_subjects is just a dummy class that only knows how to setup the layout/widgets?. In your first approach, you were aplying that layout into a base class QMainWindow, there was no link between your logic and the window. Now you are aplying the layout over the MySubjectsWindow class, that knows the operational/logic code.

#

In other words. In your first approach you were just instantiating an QMainWindow and adding the layout. Now you are instantiating an extended QMainWindow class (MySubjectsWindow) that has some logic, and aplying the layout on that.

wispy oar Mar 27, 2019, 11:41 PM

#

Oh okay, I understand now; the first block is more like a general piece of code, but the new one is directly using the class MySubjectsWindow. I do agree that it looks cleaner and I understand it more than the first one.

#

I tried replacing the QtWidgets.QMainWindow() part and it gave me the issue I had before with the operational code not working, but I guess that doesn't matter if I'll be using the other block anyway.

#

I'm not sure why my code generator adds that block at the end of the code. I saw an example of auto-generated code and it also didn't add it.

#

I just go to cmd, pushd the file directory, then use the command pyuic5 -x my_subjects.ui -o my_subjects.py.

sonic bridge Mar 27, 2019, 11:45 PM

#

I tried replacing the...
Hmm yeah, I never tried that way so I am not sure, but if the second way works then its fine.

#

maybe the autogenerated code is different because I am using pyside and not pyqt

wispy oar Mar 27, 2019, 11:46 PM

#

Oh yeah that's right I think. The other example I saw was also using PySide2.

#

Thanks for helping, I should be able to use what I learned for my other modules as well, so I can develop things more quickly and stick to the coding conventions.

#

One quick thing, do I need from PyQt5 import QtCore, QtGui, QtWidgets at the start of the operational code, or is there a way to import it from the generated code? I was thinking it might be redundant, because it's already part of the generated code.

sonic bridge Mar 27, 2019, 11:51 PM

#

I guess you dont need them, unless you access to a property/method from these packages in the operational code. Just remove those imports and test if everything works.

wispy oar Mar 27, 2019, 11:55 PM

#

I did try to remove them, and also tested if removing it and importing the whole of my_subjects_generated.py would work, but it didn't. I'll just keep it in the code, because I guess the operational code needs it.

#

Thanks again for helping, your explanations were really useful and helped me to understand what I'm doing a lot better.

PyGame would be the Python equivalent for DirectX right? GWqlabsGarThink

No. DirectX is lower level

lilac ridge Mar 29, 2019, 7:17 PM

sudden coral Mar 29, 2019, 7:18 PM

PyGame is built on SDL which actually uses OpenGL or DirectX for its graphics side of things

sudden coral Mar 29, 2019, 7:19 PM

lower level means you're more closely working with the hardware e.g. GPU

Eh, neither do I. For an hypothetical game engine (for simple 2D games, like VNs) would it be better basing it on PyGame or SDL?

sudden coral Mar 29, 2019, 7:23 PM

I don't know. It depends I suppose. PyGame doesn't offer access to SDL or the lower level things so if you find that limiting then write something yourself with SDL

It'd be a lot more work I imagine

You should use cursor.fetchall() to get the results

#

Though I suggest looking into using a QSqlDatabase with the sqlite driver. It gives you a model you can use with QTableView.

#

You may be able to still use it with a QListView, even though the model is essentially a QAbstractTableModel

How can I create a main script from which it executes other scripts which define the parts of the game in pygame?

For example let's say that there is main.py and other two scripts c1.py and c2.py. From main.py I would like to start the main loop and execute the contents of c1, when c1 is done I would like to jump to c2. How would I go around to make this? (Idk if it's really UI related but gonna post this here anyway, in case I'll remove it)

#

I doubt exec(open("./c1.py").read()) would be optimal lol

sudden coral Mar 30, 2019, 8:32 PM

#

You need to import the other files

#

import c1 for example

lilac ridge Mar 30, 2019, 8:35 PM

#

I don't think I explained this well, c1 would be just code, no functions or classes defined in it, which I would import from somewhere else. I just want to execute it

sudden coral Mar 30, 2019, 8:36 PM

when you import a module all the code in it gets executed

#

Like all the module-scope stuff

lilac ridge Mar 30, 2019, 8:37 PM

#

oh

#

yeah I've just read that up

#

I can use importlib so I don't have to hardcode it right?

sudden coral Mar 30, 2019, 8:41 PM

#

Yeah, but do you need it to not be hard coded?

#

Are you creating some sort of modular plugin system or something

#

Are module names dynamically generated?

lilac ridge Mar 30, 2019, 8:42 PM

#

No, but it would just look nicer ¯_(ツ)_/¯

sudden coral Mar 30, 2019, 8:42 PM

#

It would't IMO

#

It's unnecessary and extra complexity

#

import c1, c2 vs ```py
import importlib

importlib.whatever("c1")
importlib.whatever("c2")

lilac ridge Mar 30, 2019, 8:46 PM

#

can't I just make a for loop of a list of the files? 🤔

#

though I would probably have to create another thread that checks for basic events

Yes, you can but it's not needed unless you have a shitload of modules

I know I can use .text() to get the input, but I'm not sure what code makes the button close the dialog. If I can find that out, I'd imagine it's just a case of using an IF statement and indent that part?

sudden coral Mar 30, 2019, 9:29 PM

#

Overwrite QDialog.done()

#

When you overwrite it, to close it you'd just call super().done(the_result)

#

So if validation fails simply don't call that

#

and it will remain open

I don't have any QDialog.done() in my code.

you can only use one geometry manager in a given master window, choose either pack or grid to place your widgets

grid is fine, but the reason you can't use it is because another widget that shares the parent for label_l has either been added with pack or place first

It should just be Entry

Or Tkinter.Entry if you didn't use a wildcard import

Maybe I’m missing it but just create the entries and grid then to topframe

#

Or create a middle frame and put entries in there

#

Import Tkinter for python 2 not tkinter

#

Import Tkinter as tk

Y'all I need some help with Qt's QTreeView and my subclass of QAbstractItemModel. For some reason, even though the data for each TreeItem is being populated, the data() method for nested values isn't being called.

The offending commit can be seen here (sorry for the lack of comments): https://github.com/spikespaz/jvman/commit/919f6bce6ecd6f0d9e165bb381572576741c42f5

https://github.com/spikespaz/jvman/blob/dev/jvman/models.py#L248-L452

Sorry for the spaghetti code. If you know how to fix that (without putting the append calls in the TreeItem) lmk.

If you are going to prefix your widgets with tk. then you need to import it as such

import Tkinter as tk

root = tk.Tk()```
Or if you import all
```py
from Tkinter import *

root = Tk()```
First is better though, you should always avoid `*` imports

#

@unique spade you have to separate your widget assignment and placement

#

.grid() returns None, so that's what is being assigned to entry_1

#

you should separate them like

entry_1 = Entry(midFrame)
entry_1.grid(row=1, column=1)

unique spade Apr 2, 2019, 12:54 PM

ok works, awesome : ) thanks

unique spade Apr 2, 2019, 1:10 PM

I'm playing around with it and how to add the separators to get_all (if I wanted to get string with all info from entry)?

def get_string():
    Name_of_the_eng = entry_3.get()
    Name_of_the_pl = entry_2.get()
    Name_of_the_key= entry_1.get()
    string_to_display = "String name is: " + Name_of_the_key + Name_of_the_pl + Name_of_the_eng
    label_6= Label(Most_bottom)
    label_6["text"] = string_to_display
    label_6.grid(row=3, column=1)

karmic shoal Apr 2, 2019, 1:17 PM

what kind of separators?

#

like one | two | three?

unique spade Apr 2, 2019, 1:21 PM

normal comma would do

karmic shoal Apr 2, 2019, 1:23 PM

you could use string formatting if there's only that three items to show

one = "1"
two = "2"

print(f"Numbers are: {one}, {two}, {three}")

that's if you're using Python 3.6 or newer, if you're using <Python 3.6 you can use str.format

if you're using it learn, I'd highly suggest using Python 3, as Python 2 is retiring in 9 months

~~but till then, you can format the string using the % syntax~~

#

actually scratch that, you should still be able to use str.format

    print(string_to_display).format(Name_of_the_key,Name_of_the_pl,Name_of_the_eng)

Hey 😃 I'm currently using Tkinter and trying to figure out the best way to change the state of a button based on a text field. For example, if the characters in the text field are below a certain length, the button remains disabled, but once it passes it it returns to its normal state. So far I've got this:

root = Tk()

def update(*args):
    while True:
        if int(str(len(msg.get("1.0", 'end-1c')))) > 0:
            button.config(state=NORMAL)
            print('Yes')
        else:
            print('No')
            continue

msgLabel = Label(text="Message")
msgLabel.grid(row=0, column=0)
msg = Text(width=40, height=4, wrap="word")
msg.grid(row=0, column=1, padx=10, pady=5)

var = StringVar(root)

charCount = Label(textvariable=var)

charCount.grid(row=1, column=1, pady=5, padx=5)

msg.bind("<KeyRelease>", update)

button = Button(root, text="Working", state=DISABLED)
button.grid(row=2, column=1)

root.mainloop()```

@wispy oar Did you ever figure out that dialogue question you asked a few days ago?

wispy oar Apr 4, 2019, 2:03 PM

#

@sudden coral I didn't manage to override the method as you suggested, but I simply removed the signal from the generated code, then used .close() to close the dialog when validation is passed.

#

So the method ended up being # Saves input to a .txt file for the list of subjects. def save_subject(self): new_subject_name = self.Dialog.line_edit_subject_name.text() if len(new_subject_name) <= 30 and len((new_subject_name).replace(" ", "")) > 0: print(new_subject_name) self.list_widget_my_subjects.addItem(new_subject_name) self.list_widget_my_subjects.sortItems() with open('subject_list.txt', 'a') as outfile: outfile.write(new_subject_name + "\n") self.sort_subject_list() self.Dialog.close() elif len((new_subject_name).replace(" ", "")) == 0: self.Dialog.lbl_instruction.setText( "You have not entered a subject name. Please try again.") else: self.Dialog.lbl_instruction.setText( "Your subject name exceeds 30 characters. Please try again.")

sudden coral Apr 4, 2019, 2:05 PM

#

That's a nice solution

#

Though I'd disconnect the signal rather than modifying generated code

wispy oar Apr 4, 2019, 2:13 PM

#

Yeah that's true. I didn't think you could do that. Thanks.

#

I've coded the ability to delete a subject, but it seems like the program is having an issue when it saves the list after deleting.

#

If I delete it using the button like this: https://i.imgur.com/qxw8pYg.png

Imgur

#

Then it does delete it and views it correctly, but I think it saves it to the .txt file incorrectly. https://i.imgur.com/K14zESE.png

Imgur

#

Because if I close it and open it so it reads from the .txt file to populate the list, it appears like this: https://i.imgur.com/Qf96DWJ.png

Imgur

#

This is the code for it: ``` # Deletes the selected subject.
def delete_subject(self):
selected_item = self.list_widget_my_subjects.selectedItems()
for item in selected_item:
self.list_widget_my_subjects.takeItem(
self.list_widget_my_subjects.row(item))
self.save_subject_list()

# Saves the subject list.
def save_subject_list(self):
    with open("subject_list_temp.txt", "w") as outfile:
        for i in range(self.list_widget_my_subjects.count()):
            subject = self.list_widget_my_subjects.item(i).text()
            outfile.write(subject)
        with open("subject_list.txt", "w") as outfile:
            for i in range(self.list_widget_my_subjects.count()):

Why do you write to 2 files?

wispy oar Apr 4, 2019, 2:28 PM

#

Data atomicity, so data isn't lost if the program crashes midway.

sudden coral Apr 4, 2019, 2:29 PM

#

Can you show the code for reading the file?

#

Never mind, I spotted the issue

#

When you write to the second file, you do not update the subject

#

Therefore that variable's value remains at whatever it was last set to by the previous loop

#

That's why it's just Mathematics; it was the last subject

wispy oar Apr 4, 2019, 2:31 PM

#

Ah, I had it like that before, but I removed it because I thought it was redundant there with subject already being there above it. I didn't think about it being in the loop.

#

Okay thanks, that should fix it, I'll have a try now.

sudden coral Apr 4, 2019, 2:32 PM

#

Also, you may need to append a newline character for every subject

#

Presumably you're reading the file line by line

wispy oar Apr 4, 2019, 2:32 PM

I think it already does it when it adds a new subject.

                outfile.write(new_subject_name + "\n")```

sudden coral Apr 4, 2019, 2:33 PM

#

But that isn't present in your code above

wispy oar Apr 4, 2019, 2:33 PM

#

That's for deleting a subject.

#

You'll be deleting '\n', but you'll still have '\n' from the first subject, wouldn't you?

sudden coral Apr 4, 2019, 2:34 PM

#

Yes, but you completely re-write the list when you save

#

The new line is not included as text in the item for the widget

#

Actually I can't be sure because I don't know how you're reading the file

wispy oar Apr 4, 2019, 2:35 PM

#

Yeah I think you're right now that I've tried it.

sudden coral Apr 4, 2019, 2:35 PM

#

It just looks like it's only writing a single line based on the second picture

#

Though if you were right I suppose that could be happening just because the last subject wouldn't have a newline after it

wispy oar Apr 4, 2019, 2:37 PM

#

No I just tested it, you were right because the code replaces \n when populating the list.

#

        with open("subject_list.txt", "r") as data_file:
            subject_list = data_file.readlines()
            print(subject_list)
            print(len(subject_list))
            for line in subject_list:
                self.list_widget_my_subjects.addItem(line.replace("\n", ""))
            self.list_widget_my_subjects.sortItems()
            self.sort_subject_list()```

#

This part makes it necessary to add the \n anyway.

sudden coral Apr 4, 2019, 2:40 PM

#

You could simplify the replace with a strip

wispy oar Apr 4, 2019, 2:41 PM

#

That's a good idea, thanks. I've done .replace() three times like that.

@proper glade suggested using QHeaderView::section {background-color: transparent}, and I also tried removing the QHeaderView part (because the link from above was for QTableView, not QTableWidget, but it doesn't make any difference.

i found out that if i'm not mistaken, pyqt doesn't have anything to return listwidget item text, and i should get it with QModelIndex, how can i make one of this for my listwidget?

https://www.riverbankcomputing.com/static/Docs/PyQt4/qmodelindex.html#sibling

kind kraken Apr 4, 2019, 6:15 PM

#

@fast wave did you try .currentItem().text() like I suggested?

#

@mighty frigate is there a thing for the body that you could set the red bg on instead of the whole control

#

there's ::item but that won't style the dead space to the bottom and right

fast wave Apr 4, 2019, 6:26 PM

#

@kind kraken .currentItem().text() won't work and doesn't return anything. but currentRow() returns index from 0 till whatever. and .item(index) returns the text items itself. i don't know why it still says : results = self.cur.execute("SELECT English FROM Words WHERE Esperanto = ?", (esperanto,))
sqlite3.InterfaceError: Error binding parameter 0 - probably unsupported type.

#

        index = self.listWidget.currentRow()
        esperanto = self.listWidget.item(index)
        results = self.cur.execute("SELECT English FROM Words WHERE Esperanto = ?", (esperanto,))
        for row in results:
            self.textEdit.clear()
            self.textEdit.insertPlainText(row)```

#

if i remove index from .item again won't work it needs int as prameter, which i'm doing now.

wispy oar Apr 4, 2019, 6:28 PM

#

@fast wave You have to use a for loop and an index.

#

This is what I used: # Saves the subject list. def save_subject_list(self): with open("subject_list_temp.txt", "w") as outfile: for i in range(self.list_widget_my_subjects.count()): subject = self.list_widget_my_subjects.item(i).text() outfile.write(subject + "\n")

#

@mighty frigate I tried it in the Qt Creator style sheet and it didn't work, perhaps I'm typing it wrong?

@fast wave what kind of object is esperanto now? do you still have print(repr(esperanto)) in there before that line?

@kind kraken repr for esperanto returns: <PyQt5.QtWidgets.QListWidgetItem object at 0x0000000002C0D4C8>

@wispy oar thanks

kind kraken Apr 4, 2019, 6:50 PM

any chance you can get .text() on it?

#

sorry i can't be more helpful

fast wave Apr 4, 2019, 6:59 PM

#

no text doesn't work. esperanto = self.listWidget.item(index).text()
AttributeError: 'NoneType' object has no attribute 'text'

kind kraken Apr 4, 2019, 7:33 PM

#

...i thought it was a QListWidgetItem

#

why is it None now

#

maybe it's only sometimes set?

#

try py def listClicked(self): index = self.listWidget.currentRow() item = self.listWidget.item(index) if item is not None: esperanto = item.text() results = self.cur.execute("SELECT English FROM Words WHERE Esperanto = ?", (esperanto,)) for row in results: self.textEdit.clear() self.textEdit.insertPlainText(row)

#

wait actually

#

can i see the rest of your code?

#

there's an itemClicked event that might be a better fit for what you're doing

#

@fast wave

fast wave Apr 4, 2019, 7:38 PM

#

@kind kraken whole code is this: https://bpaste.net/show/d1ead5e2526f

kind kraken Apr 4, 2019, 7:38 PM

#

so it is itemclicked, you just don't have the

#

try this

#

    def listClicked(self, item):
        if item is None: return
        esperanto = item.text()
        results = self.cur.execute("SELECT English FROM Words WHERE Esperanto = ?", (esperanto,))
        for row in results:
            self.textEdit.clear()
            self.textEdit.insertPlainText(row)```

#

it's so weird that pyqt lets you do that

#

any other ui framework would be screaming about passing the function too many arguments

fast wave Apr 4, 2019, 7:39 PM

it says

#

self.listClicked()

#

remove the self.listClicked() line from setupUi

actually i bet that was your whole problem

with the None

i removed it now another error.

self.textEdit.insertPlainText(row)

fast wave Apr 4, 2019, 7:42 PM

#

wow! it works 😃 thanks a bunch.

kind kraken Apr 4, 2019, 7:42 PM

#

no problem

#

sorry for getting stuck on this so long, i should have thought about looking at the itemClicked event

#

i guess pyqt doesn't care if you put a function with the wrong arguments in an event

#

(if you put too many arguments though it'll hard crash, i ran into that with something else last month)

fast wave Apr 4, 2019, 7:44 PM

#

so i deleted if item is None: return because i guess if a row be empty it'll return none, but i have no empty row.

kind kraken Apr 4, 2019, 7:47 PM

#

yeah i think it was only because of that first call

#

it didn't have a selected item

#

you might consider handling the itemSelectionChanged event for keyboard usage - click is click only aiui

#

but at least what you have is working now

fast wave Apr 4, 2019, 7:49 PM

yes later i should add functionality to search with return button on keyboard too.

and make that lineedit autocomplete or filter listwidget 😄

@wispy oar I don't personnaly use the designer

but I'm pretty confident with the code I gave you

@kind kraken the doc is explicit, there's a specific selector to use in order to style the corner - if that's what you're talking about.

@mighty frigate I tried it but I couldn't get it working. Maybe I've put the code in the wrong place, because my program works a bit different. https://paste.pythondiscord.com/daxiqoyuhi.py

It imports the generated code from pyuic5. I tried putting both in and out of the AgendaWindow class.

#

And changed the variables to match.

Isn't your code for changing the colour of the whole window? I just need the widget to be transparent in the background.

@mighty frigate that means the top left corner, I mean empty space within the main area that isn't part of a cell

if you care about that being red or whatever color

mighty frigate Apr 4, 2019, 10:46 PM

#

the doc is explicit

#

https://doc.qt.io/qt-5/stylesheet-reference.html#QTableView

more specificaly

#

The corner widget in a QTableView is implemented as a QAbstractButton and can be styled using the "QTableView QTableCornerButton::section" selector.

this would need some tries I guess ,rn Idk

since it sounds like you want the dead space and items to be red, without making any of the rest of the control red

#MyObject {

and to my knowledge, this is not valid

also you should have the debugger screaming at you for putting bad qss rules

#

are you able to select the headers directly and add rules?

wispy oar Apr 4, 2019, 11:01 PM

#

Yeah, removing that first line does change things, but it makes things all white, so I think the code isn't working when put into Qt Creator this way. Perhaps it's a different format.

#

It worked when I just put it directly in the code.

#

Thanks, I'm just really curious about why it won't work with Qt Creator, and why background-color: transparent only makes the data area transparent. I think I'm either inputting it in the wrong place or the format is different.

Hi, I am new to GUIs, I made a little proyect with tkinter, and is ugly as fuck

#

📎 unknown.png

#

What should I use for make something like that that will not make my mates eyes cry with blood?

#

The other module I know is Pqt5, but I never used it or anything

rugged sinew Apr 6, 2019, 1:08 AM

#

@unique python even in tkinter, there's something called ttk, which would look a lot better than this.

#

that'd be the smallest step you could take towards a better looking GUI

#

QT will make a truly native-looking GUI, and you might want to look into something called pyside2 if you're gonna head down that route.

#

it's the official Qt for Python module, and is quite popular.

#

but a slightly larger learning curve from what I've heard. still shouldn't be too bad.

unique python Apr 6, 2019, 1:17 AM

#

Thanks @rugged sinew for your answer. Now I was trying the Qt designer that I downloaded from https://sourceforge.net/projects/pyqt/files/PyQt5/PyQt-5.6/, but what's the difference between that that and pyside2?, or the difference is that one is GUI for making GUIs and the other (pyside2) is a module to make GUIs?

PyQt - Browse Files at SourceForge.net

The GPL licensed Python bindings for the Qt application framework

rugged sinew Apr 6, 2019, 1:17 AM

#

yeah that's essentially it

#

pyside just lets you write code, like tkinter

#

I hate using that designer personally because it generates a bunch of ugly code

#

I'd rather just write my own

#

besides, you're not gonna learn any python from using the designer :P

unique python Apr 6, 2019, 1:20 AM

#

I will not learn to create widgets and set theirs properties, but anything else I will have to do it by code

#

You really helped me, I will take in to account using pyside2, but the designer looks seductive 👄 haha, thanks.

kind kraken Apr 6, 2019, 1:25 AM

it is possible to make that tkinter app less ugly

e.g. align the labels to the left, stretch the entry boxes

proper glade Apr 6, 2019, 2:32 AM

#

say youve got a grid of objects that you use the mouse with various modifiers to interact with.
is there an established design pattern for implementing the handling the mouse/keyboard in this kind of situation?

#

i guess a plain old state machine could work

#

this is what it looks like

📎 2019-04-06_15-32-18.mp4

#

at the start it's just left drag with no modifiers, then alt + left drag which lets you 'draw' outside the current line, then shift which lets you select individual cells

#

and then there's the right click variation of all these which handles turning off/deselection

#

right now it's all basically hard coded into the event handlers

#

but i'm finding that it's getting a bit cumbersome to work with

#

like if i want to add more modifiers later down the road im gonna have to add cases to all the previous branches in every event handler to accommodate them

kind kraken Apr 6, 2019, 3:52 AM

#

@proper glade It looks like you could handle tht with mousedown and mousemove alone

#

mousedown: sets the row that non-alt drawing is constrained to

#

invoke the same as mousemove

#

mousemove: pick cell based on mouse position (and constrain row if alt is not down), then set state based on which button is down and whether shift is pressed

proper glade Apr 6, 2019, 3:54 AM

ok idk what's cumbersome then

proper glade Apr 6, 2019, 3:55 AM

#

so im looking for a better way to handle it with some kind of established design pattern instead of hard coding all the cases

kind kraken Apr 6, 2019, 3:55 AM

#

maybe the structure of your code isn't what i'm picturing

proper glade Apr 6, 2019, 3:55 AM

#

im working on a state machine atm

kind kraken Apr 6, 2019, 3:55 AM

#

what state

#

the only state is the constrain row

#

can you show me your code? maybe we're talking past each other

proper glade Apr 6, 2019, 3:55 AM

#

youve got a bunch of key/mouse button states that can be combined in different ways

#

gotta handle any of them being on/off at any time

kind kraken Apr 6, 2019, 3:55 AM

#

yeah but none of that is state

proper glade Apr 6, 2019, 3:56 AM

#

or one turning off during a drag

kind kraken Apr 6, 2019, 3:56 AM

#

or, rather, it's not your state, in the sense of a state machine

proper glade Apr 6, 2019, 3:56 AM

#

sure it is. state of input.

#

combined keyboard/mouse state.

kind kraken Apr 6, 2019, 3:56 AM

#

each drag movement is a separate event, and you check the modifiers in the event handler right

#

ok but i don't understand what's cumbersome, or what adding a modifier would require you to change in multiple places

#

nothing in the model i suggested does that

proper glade Apr 6, 2019, 3:56 AM

#

lemme upload some code

#

hopefully that'll make it a bit clearer

kind kraken Apr 6, 2019, 3:57 AM

#

but then i'm making assumptions about your data model too

#

it's not state in the sense of being state that you set, which is what "state machine" normally implies: each stage sets the state for the next stage to pick up

proper glade Apr 6, 2019, 4:00 AM

#

you are setting the state, by funneling it input from the input devices.

#

i.e. 'key x on', 'key x off'.

kind kraken Apr 6, 2019, 4:00 AM

#

uh what

#

you should be able to check current modifier state without handling keydown events, in most frameworks

proper glade Apr 6, 2019, 4:01 AM

#

im talking about the state machine

#

one central state machine that handles what action the combined keyboard/mouse state should be carrying out

kind kraken Apr 6, 2019, 4:03 AM

#

i don't understand where that's happening in your code

proper glade Apr 6, 2019, 4:03 AM

#

yeah, sorry, not the cleanest atm 😛

kind kraken Apr 6, 2019, 4:03 AM

#

or where you're checking alt at all in your code

proper glade Apr 6, 2019, 4:03 AM

#

alt is in mouseMoveEvent

#

oh wait this is the code for editing the graphs, not sequences 😅

#

one sec

#

https://paste.pydis.com/heyizupexo.py there ya go

#

        modifiers = qt.qApp.keyboardModifiers()

        if modifiers & qt.constants.AltModifier:
            y = event.globalY()
        else:
            y = self.mapToGlobal(qt.QPoint(0, 0)).y()

        widget = qt.qApp.widgetAt(event.globalX(), y)```

#

the history stuff is also something you didn't mention

proper glade Apr 6, 2019, 4:06 AM

#

ah yeah sorry lol

kind kraken Apr 6, 2019, 4:07 AM

#

that actually complicates things a lot

proper glade Apr 6, 2019, 4:07 AM

#

didnt think it would be that important. i feel like theres a general way to solve the problem that the history stuff could fit into easily.

kind kraken Apr 6, 2019, 4:07 AM

#

sure but

#

without the history thing you wouldn't have to check keyup events at all

#

and with it, you have to have special handling for if they press or release shift while the mouse is held down

proper glade Apr 6, 2019, 4:07 AM

#

not yet, anyway

#

im trying to plan ahead

#

in case i want to add another modifier similar to the history stuff that -will- need key release checking

#

just wanna go about it in a way that's easier to manage/expand that what i currently have

kind kraken Apr 6, 2019, 4:08 AM

#

er, like i said, you have to handle it now if they press or release it while the mouse is held down

proper glade Apr 6, 2019, 4:09 AM

#

that was meant to be in response to without the history thing you wouldn't have to check keyup events at all

kind kraken Apr 6, 2019, 4:09 AM

#

right

#

anyway, your duplicate code between the mousedown and move can probably be factored out

#

to a single function called by both

#

incidentally part of where i was confused about the state machine thing

#

i'm pretty sure you can get the drag button from the modifiers, in the mouse move event

proper glade Apr 6, 2019, 4:10 AM

#

you can, event.buttons()

#

the reason why i have one drag_button is in case you have like

#user-interfaces
