You should check the pins in this channel for how to install kivy with python 3.8. It's a bit different than just pip install kivy

static cove Aug 24, 2020, 4:35 PM

#

tkinter is part of the standard library, so you don't have to install anything else. As long as you have python you're good

and how to make my own custom look of gui?

#

or i should ask, how to use custom gui that i could design by myself?

@static cove ah okay thank you

maiden dragon Aug 24, 2020, 11:36 PM

I'm having some painting problems with the background of my GUI.

When I create my GUI I set the background for the main panel as a bitmap and I do some double buffering so I can scroll around the window.

The issue is I want to implement a darkmode by replacing the bitmap with a new one.

This works however whenever I scroll to a new part of the window it the new area reverts to the original background

#

The way I am changing the background right now is deleting the pannel and remaking it with the path changed to the new image

Hey have a question maybe someone can help me? For example, if I have a project in Python and I want to do an API in Java or PHP, how would that work?

plush stream Aug 25, 2020, 10:35 AM

Hey, so. I made a dark theme for my eq, but the scale/slider has that weird white border around it, how do i get rid of it?

Okay then, guess i'll revert to light theme for the eq

novel cloud Aug 25, 2020, 11:38 AM

hmm i liked the dark theme

#

hey try to change the width of the whole board

plush stream Aug 25, 2020, 11:38 AM

Just for the eq, the player stays dark

novel cloud Aug 25, 2020, 11:38 AM

its def padding issue

isnt their like inspector for it

or u can just leave the shit like that and make ur bg a bit dark too..... bahhaha

plush stream Aug 25, 2020, 12:15 PM

#

The bg itself is already dark, hehe

#

I've tried to change the fg too, but no avail

maiden dragon Aug 25, 2020, 3:37 PM

#

@plush stream issue I am having is also related to trying to implement a darkmode. does your stuff at all involve changing from one bitmap to a different one

plush stream Aug 25, 2020, 3:39 PM

#

I don't know what do you mean by bitmap, are you talking about the app's icon?

maiden dragon Aug 25, 2020, 3:40 PM

#

i was wondering if it involved loading a bitmap into the app and switching to a new one when you enable dark mode

#

like in my case its for a background image

plush stream Aug 25, 2020, 3:41 PM

#

Ah got it, and no, that's doesn't seems to be the case for this one

maiden dragon Aug 25, 2020, 3:41 PM

#

damn I'm having a bunch of issues switching to a new background image

hard trail Aug 25, 2020, 3:41 PM

Hey anyone that can help me, i cannot figure out why my variable is empty. i want to get the contents of a tkinter Entry

#

class Register:

    def __init__(self):
        self.registerWindow = Tk()
        self.registerWindow.title("Register with python")
        self.registerWindow.geometry("300x250")
        self.label = Label(self.registerWindow, text="Register")
        self.label.place(x=95, y=40)

        self.usernameS = StringVar()
        self.passwordS = StringVar()

        self.usernameE = Entry(self.registerWindow, relief=FLAT, textvariable=self.usernameS)
        self.usernameE.place(x=70, y=80)
        self.passwordE = Entry(self.registerWindow, relief=FLAT, show="*", textvariable=self.passwordS)
        self.passwordE.place(x=70, y=120)

        self.submit = Button(self.registerWindow, text="Submit", pady=5, padx=20, command=self.add)
        self.submit.place(x=100, y=150)

        

    def run(self):
        self.registerWindow.mainloop()


    def add(self):
        self.username = self.usernameS.get()
        self.password = self.passwordS.get()

        # THIS RETURNS EMPTY SO THE DATABASE DOESNT PUT ANY DATA IN ASWELL!
        print("Entered username is: " + self.username)
        print("Entered password is: " + self.password)

        self.salt = bcrypt.gensalt()
        self.hashed = bcrypt.hashpw(self.password.encode(), self.salt)

        print("from add: " + self.username)
        data = (self.username,)

        result = db.searchData(data)

        print("From add method result is: " + str(result))

        if result != 0:
            data = (self.username, self.hashed)
            db.insertData(data)
            messagebox.showinfo("Successful", "Username was added")
        else:
            messagebox.showinfo("Warning", "Username aldready Exists")```

#

the print statement returns an empty line

#

i cannot figure out why its not getting the contents i typed in

maiden dragon Aug 25, 2020, 3:42 PM

#

which print?

hard trail Aug 25, 2020, 3:42 PM

#

oh sorry removed it 1 sec

#

so its not getting the contents from the Entry

#

its blank

#

has todo something with self.username = self.usernameS.get()

#

because the contents of that is empty and is not the username i typed in

#

so any help on this would be appreciated

plush stream Aug 25, 2020, 3:45 PM

#

Try .get(0, END)

hard trail Aug 25, 2020, 3:46 PM

#

self.username = self.usernameS.get(0, END) TypeError: get() takes 1 positional argument but 3 were given

plush stream Aug 25, 2020, 3:47 PM

#

Oh dangit, sorry. That wouldn't work with .get function

hard trail Aug 25, 2020, 3:47 PM

#

no problem the help is appreciated

plush stream Aug 25, 2020, 3:47 PM

#

Oh, i remember something

#

I've faced this issue before, i removed the variable,
Instead of

Print(self.username)```

It'll be like this ``` Print(self.usernameS.get())```

#

That would work in my case so, you should try it

hard trail Aug 25, 2020, 3:52 PM

#

okay ill try it 🙂

@hard trail How is the add function being called?

#

Is it just the submit button or is anything else calling it?

#

Also, the code you have there works for me (up until the bcrypt because I don't quite feel like getting that running). The self.username and self.password don't return empty for me.

hard trail Aug 25, 2020, 4:14 PM

#

@static cove the submit button is calling it

#

for me they return empty weird

static cove Aug 25, 2020, 4:15 PM

#

Just to double check, how are you setting up the instance of the Register and calling it?

hard trail Aug 25, 2020, 4:15 PM

#

from login import Login, Register

    def __init__(self):
        self.app = Tk()

        self.login = Button(self.app, text="Login", pady=5, padx=30, command=login)

    loginTk = Login()
    loginTk.run()

    registerTk = Register()
    registerTk.run()


app = MainWindow()
app.run()```

static cove Aug 25, 2020, 4:16 PM

#

Thaaaat would probably do it. Give me a second to confirm why I think it's not working and I can do a small write up

hard trail Aug 25, 2020, 4:16 PM

#

Thanks alot 🙂

static cove Aug 25, 2020, 4:18 PM

#

@hard trail Yup! It has to do with the fact that you have a Tk() in the MainWindow class and and Tk() in the Register class. Those are separate instances of the Tcl interpreter and it is very, very, very highly recommended to only have one of them per app. If you have more than one things get a bit screwy and data doesn't get passed properly

hard trail Aug 25, 2020, 4:18 PM

#

ah okee 🙂

#

how could i fix that

static cove Aug 25, 2020, 4:18 PM

#

A super easy fix, is to change the self.registerWindow = Tk() in the Register class to self.registerWindow = Toplevel()

hard trail Aug 25, 2020, 4:18 PM

#

ah yeah

#

i remember that indeed

static cove Aug 25, 2020, 4:19 PM

#

That'll still create it's own standalone window, but it'll still be in the same Tcl interpreter

hard trail Aug 25, 2020, 4:19 PM

#

in TopLevel(i need to pass something here right)

static cove Aug 25, 2020, 4:19 PM

#

Just self.registerWindow = Toplevel() should work

hard trail Aug 25, 2020, 4:20 PM

#

okay fingerscrossed

maiden dragon Aug 25, 2020, 4:21 PM

#

kat if you are available could i post some code for painting for you to look at?

static cove Aug 25, 2020, 4:21 PM

#

@maiden dragon yes! Is it the darkmode wxPython thing? If so, I'm currently loading up my venv for wxPython troubleshooting

maiden dragon Aug 25, 2020, 4:21 PM

#

yeah yeah TYVM

#

ill try and get to relevant code copied

#

so when i set it to dakrmode i do this

def ontoggledark( self, event ):
        self.darkmode = True
        del self.panel_left
        self.Refresh()
        self.__do_layout()
        #event.Skip()

essentially delete the panel and remake it calling the new bitmap

class col_panel(wx.ScrolledWindow):
    def __init__(self, parent, darkmode):
        """Constructor"""
        wx.ScrolledWindow.__init__(self, parent= parent)
        self.maxWidth  = 1410
        self.maxHeight = 995
        self.SetVirtualSize((self.maxWidth, self.maxHeight))
        self.SetScrollRate(15, 15)
        self.run = False
        

        if darkmode == False:
            self.SetBackgroundColour((254, 254, 242))
            column = (resource_path(r"Imagefiles\col.png"))
            #break
        else:
            self.SetBackgroundColour((4,5,35))
            column = (resource_path(r"ImagefilesDark\col.jpg"))

        self.bmp = wx.Bitmap(column)

        self.columnbutt = wx.Button( self, wx.ID_ANY, u"Column Internals", pos = (340, 906))
        self.Bind(wx.EVT_BUTTON, self.oncolbut, self.columnbutt)

        if BUFFERED:
            # Initialize the buffer bitmap.  No real DC is needed at this point.
            self.buffer = wx.Bitmap(self.maxWidth, self.maxHeight)
            dc = wx.BufferedDC(None, self.buffer)
            dc.SetBackground(wx.Brush(self.GetBackgroundColour()))
            dc.Clear()
            self.DoDrawing(dc)
        self.Bind(wx.EVT_PAINT, self.OnPaint)

col_panel is created in __do_layout and should be created with the new bitmap

hard trail Aug 25, 2020, 4:24 PM

#

for somereason im unable to find the right import for TopLevel

static cove Aug 25, 2020, 4:24 PM

#

@hard trail what do your import statements look like?

hard trail Aug 25, 2020, 4:24 PM

#

from tkinter import *
from tkinter import messagebox
import bcrypt
from database import Database

#

i tried from tkinter import TopLevel

#

but didnt work

maiden dragon Aug 25, 2020, 4:25 PM

#

i don't think deleting the panel is really a good solution tbh but I'm sure the best way to repaint the background plus i am using a scrolledwindow so everything is in damn virtual window lol

static cove Aug 25, 2020, 4:25 PM

#

@hard trail ah, it needs to be Toplevel not TopLevel. Only the T is capital

hard trail Aug 25, 2020, 4:26 PM

#

ah duhh im feeling so dumb

#

XD

static cove Aug 25, 2020, 4:27 PM

#

@maiden dragon why delete the panel? Can you not just change the panel's background without deleting it? (I'm still getting caught up wxPython stuff, so sorry if that's a dumb clarification)

maiden dragon Aug 25, 2020, 4:28 PM

#

mostly cause this was assigned to someone else and that was their idea, i dont think thats a good way to do it im just not sure how to do it properly

#

it actually works fine if you keep the window maximized and never create any scroll bars but for people with smaller displays thats not an option

hard trail Aug 25, 2020, 4:29 PM

#

@static cove I want to thank you very much

#

its finally working

#

You are awesome

#

even my passwords are properly hashed so thats nice

static cove Aug 25, 2020, 4:30 PM

#

Well, I wouldn't necessarily go with deleting the object and recreating it. That seems like unnecessary overhead and very micro-manage-y.

I'd have to read up again on python gc, but I think calling del just schedules the object for collection, it doesn't necessarily do it automatically.

maiden dragon Aug 25, 2020, 4:30 PM

#

yeah what i would prefer is a way to just delete the background and repaint it with the new bitmap

trim ibex Aug 25, 2020, 4:31 PM

#

in tkinter i'm using filedialog.askopenfilename from a secondary window, and it's bringing the main window to the front. anyone else experience this?

hard trail Aug 25, 2020, 4:32 PM

#

you can do Tk().withdraw @trim ibex at least i used that and then you get just 1 dialog screen

static cove Aug 25, 2020, 4:32 PM

#

I don't think you necessarily need to delete the background, but just set a new one with the new bitmap.

maiden dragon Aug 25, 2020, 4:33 PM

#

well when i scroll to a new portion of the window i see the old background so thats what made me think that

static cove Aug 25, 2020, 4:33 PM

#

Do you have a function to handle the re-painting when you scroll?

trim ibex Aug 25, 2020, 4:33 PM

#

yeah but i want more than one window

static cove Aug 25, 2020, 4:33 PM

#

Curious if something wonky is going on there

maiden dragon Aug 25, 2020, 4:33 PM

#

yeah let me paste it for ya

trim ibex Aug 25, 2020, 4:34 PM

#

my main window has a menu item that opens an informational window. on that informational window i click a button to open a file

#

when i do that the main window jumps to the front

maiden dragon Aug 25, 2020, 4:34 PM

#

!paste

proven basinBOT Aug 25, 2020, 4:34 PM

#

Pasting large amounts of code

If your code is too long to fit in a codeblock in discord, you can paste your code here:
https://paste.pydis.com/

After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.

trim ibex Aug 25, 2020, 4:34 PM

#

atm i have it doing a raise on the informational window afterwards, but it looks crude

maiden dragon Aug 25, 2020, 4:34 PM

#

https://paste.pythondiscord.com/ugutifexug.py @static cove

#

that should be the class and how i have it handling painting for the scrolled window

#

you can ignore OnMove

static cove Aug 25, 2020, 4:39 PM

#

So, is darkmode only able to set itself on initialization?

maiden dragon Aug 25, 2020, 4:39 PM

#

the its done now yeah but not sure thats a great idea

#

ideally you can change it at any point

trim ibex Aug 25, 2020, 4:41 PM

#

i tried making the window topmost before opening the dialog, but then it just says in front of the dialog 😦

#

there's no reason an open dialog should even change the window order

static cove Aug 25, 2020, 4:43 PM

#

do you need the PrepareDC function in the else in OnPaint? My guess is something odd is happening inside the PrepareDC and DoDrawing

maiden dragon Aug 25, 2020, 4:44 PM

#

I "think" i do because i think that allows it to handle the virtual area but i don't entirely know, I'm thinking maybe i can just recall DoDrawing from outside the class

#

and feed in the new bitmap

static cove Aug 25, 2020, 4:44 PM

#

although I'm not actually certain how often it goes to that part of the conditional... so it could be an oddity inside BufferedPaintDC

maiden dragon Aug 25, 2020, 4:45 PM

#

ill try commenting out the else stuff and see

static cove Aug 25, 2020, 4:45 PM

#

even a simple count for if it's in that part or not could help

maiden dragon Aug 25, 2020, 4:46 PM

#

tbh i don't think the else ever runs bacuse Buffered is just set to 1 at the begining of the file

#

yeah commenting it out did nothing so i dont think i even use it

static cove Aug 25, 2020, 4:47 PM

#

Okay, so let's look at the BufferedPaintDC

#

It's only when you scroll that you get the non-darkmode background?

maiden dragon Aug 25, 2020, 4:47 PM

#

yeah, though that was when i was reinitializing the entire panel which seems unnecessary

#

just reverted some changes bacj to how i showed them to you gonan test that

#

yeah all of the same issues, but i think reinitializing the whole class seems liek a bad way to do things anyways

#

ok i think i mostly fixed it

#

or rather the issue now seems better so progress XD?

static cove Aug 25, 2020, 4:55 PM

#

definitely progress!

#

What have you done so far?

maiden dragon Aug 25, 2020, 4:55 PM

#

def ontoggledark( self, event ):
        bmp = wx.Bitmap((resource_path(r"ImagefilesDark\col.jpg")))
        dc = wx.BufferedDC(None, self.panel_left.buffer)
        self.panel_left.DoDrawing( dc, bmp)
        self.panel_left.SetBackgroundColour((4,5,35))
        self.panel_left.Refresh()

#

now using this instead of re initializing the panel i just added the refresh so im about to see if that fixes the problem

#

basically it doesnt update untill i make the window reall small and then make it big again

#

yay! that is a lot better but one tiny issue lol

#

top left still stays the old color and idk why

📎 unknown.png

#

dont worry about the PV,SP and mode being wrong color i just havent added that in yet

static cove Aug 25, 2020, 4:58 PM

mmmmmm, getting hella flashbacks to my distillation and labs undergrad class.

you a chemical engineer?

#

That's my undergrad degree, yeah

really curious then what do you do now?

if you don't mind me asking

Work full time for an org doing R&D type thing. Lots of modeling and simulation (mostly due to my comp sci minor). I'm also attending grad school part time for an MS in mechanical engineering

im trying to get into advanced process controls so simulations are a large part of what i wanna do, this project is actually meant to model a DCS system for students to use in our distillation lab class

Getting a lot of ASPEN vibes

maiden dragon Aug 25, 2020, 5:02 PM

#

lol well then youd love the program thats basically the engine of this GUI

#

spoiler its ASPEN HYSYS

static cove Aug 25, 2020, 5:02 PM

#

But it's curious. It seems the border on the left is bounded by the size of your actual interface window

trim ibex Aug 25, 2020, 5:03 PM

#

ok i figured out my issue. apparently the file dialog wants a "parent" parameter of what window to put the open dialog in front of. i then found a function to get tkinter's topmost window and fed it that

maiden dragon Aug 25, 2020, 5:03 PM

#

if i don't set the background i get this

#

📎 unknown.png

#

as expected

#

but cant figure out why it won't set the whole thing

static cove Aug 25, 2020, 5:03 PM

I wonder if when you set the background it's only starting from the top left of the image/graphic area and continuing from there. Or there's some sort of border that's overriding near the top

well when i initialize the window it sets the whole thing

no worries! Feel free to ping me anytime about this stuff. I don't do a lot of systems processing or controls at my current job, but I did enjoy it in undergrad

maiden dragon Aug 25, 2020, 5:08 PM

#

TYVM, im graduating undergrad this December so i may even try to apply at aspen lol not really sure where all the process controls jobs are

static cove Aug 25, 2020, 5:09 PM

#

Companies that still do a lot of processing in the states will have their own process control items. So anywhere that does a lot of manufacturing. Even some of the more complicated beer distilleries and stuff like that.

#

and of course the companies that make that software

maiden dragon Aug 25, 2020, 5:11 PM

hmm thats nice, i worked for a company that makes medical garements with viral barriers they are making bank right now so i may hit them up

Hey guys,
I dont know if this fits here well as I assume to use Matplotlib or OpenCVs cv2.imshow but I need some advice about the user interaction with an image displayed.
The software I am planing will be open source to help a medical study about diabetes and overweight.

The user has to define multiple (two) regions of interest on an Image defined by exactly 3 points (triangles).
Existing triangles have to be changeable, so the user should be able to drag and drop an existing point of a trinangle to a new location.
In OpenCV there are prebuild rectangular bounding boxes to use.
In Matplotlib there are a bunch of events and stuff I could build this on.
But as I have not so much time to build this app I would like to here if you could give me a hint for a smart and user friendly solution I am not aware of.

hello all

is anyone familiar with Gtk library?

im trying to make a listbox scrollable. im loading content from a web api and the list is pretty big. not sure how to go about adding scrolling to it.

so, about Python GUIs..
I’ve seen people recommend against Python for GUIs and suggest .NET or Java. I’ve kind of forgotten those languages for now, and I’m kind of in a rush... what do you guys think about this?
Related question... are installer GUIs possible (or should I stick to command line based installer interfaces)?

rocky dragon Aug 27, 2020, 10:53 AM

#

.net and Java will be more suitable for their main platforms (win, mobile) but python can handle desktop apps perfectly fine thorough libraries like pyqt/pyside (Qt bindings), kivy, tkinter or any of the other GUI libraries. Mobile is a bit harder but it's possible to build kivy apps for it (or Qt but that strays away from python in the frontend code)

coral oriole Aug 27, 2020, 12:23 PM

I have been using wxGlade to generate decent UIs so far. I was wondering if there was any similar -yet better- option out there. Also, what would be the best practise to develop portable apps with a python background ?

What language does flutter use ?

#

I want to make an app and ive been wondering what tools to use

#

I know the basics of python so maybe kivy idk which one is better guys ?

whole dagger Aug 27, 2020, 6:12 PM

#

Flutter uses dart. Both kivy and flutter is cross platform. Personally I prefer Flutter since it just looks better and dart is very easy to learn, similar to Java. Kivy is also nice and might be easier if you only know python. Your best bet is just to try both and see which one you like the most.

tkinter is a real pain and can be super clumsy but use your skills to abstract and subclass everything

#

if a widget is missing something that it should have (like clear() on a Text widget), add it!

#

i made a draggable class so i can just subclass everything and now all my widgets are draggable with the middle mouse button. i think i'll work in a design mode for this. here's what i got my project looking like (doesn't look like tkinter and that's a good thing): https://i.imgur.com/3dnnHRL.gif

Imgur

#

added a hover color to buttons, and i have labels using the background of their parent (either a tk or ttk container) to fake transparent background

#

one thing to note about tkinter-- if it's important to you that everything looks the same on every platform you probably want to go with something different. tends to have quirks for different os. if you can test everything well then it's not such an issue

#

qt is heavy but better all around. sometimes it gives you hard to track down complications though

        self.client = client

        self.main_box = Gtk.Box(orientation=Gtk.Orientation.HORIZONTAL, spacing=5)
        self.add(self.main_box)

        self.menu = Gtk.Box(orientation=Gtk.Orientation.VERTICAL, spacing=5)

        self.button_products = Gtk.Button(label="Products")
        self.button_products.connect("clicked", self.list_products)
        self.menu.pack_start(self.button_products, False, False, 5)

        self.button_accounts = Gtk.Button(label="Accounts")
        self.button_accounts.connect("clicked", self.list_accounts)
        self.menu.pack_start(self.button_accounts, False, False, 5)

        self.display = Gtk.Box(orientation=Gtk.Orientation.HORIZONTAL)
        self.display_scroll = Gtk.ScrolledWindow()

        self.listbox = Gtk.ListBox()
        self.display_scroll.add(self.listbox)

Is it just me or is layouting in pyqt5 (designer) hard, I just can't get things to be where I want. I want a button to have a fixed height but be expandable in terms of width so I created a frame and put the button in it, placed it in the bottom. Similar to pack(side="bottom") in tkinter. Then I chose gridlayout for the window and everything gets screwed. Can someone link me to a tutorial for layouting? I wish it could be similar to tkinter.

@trail wasp you need to hold a reference to the image outside that function. Otherwise it's getting gc'd as soon as the function finishes

@sturdy pine I'm gonna take a look at this today, but my guess is you need to do a specific layout with QForm, otherwise it'll default to the 2 columns

How can I add a new window in qt designer that is separate from main window?
@serene oriole same question

#

but i guess there must be two separated project and one shows up on event like click on button

#

but not really sure so i would like to know how to as well

serene oriole Aug 30, 2020, 2:14 PM

#

@placid nebula yeah I found you gotta create a separate window and on click make it show up

#

my first time using pyqt5..

#

or any gui library tbh

idk but i feel code created form qt is messy

placid nebula Aug 30, 2020, 2:19 PM

void bramble Aug 30, 2020, 2:21 PM

everything is in the class and organized. I wonder if I do not understand the clean code. I made an application with a user interface, but I'm a beginner out of most people here

(everybody says I'm not able to write clean code)

#

Anyone help me pls

#

🥺

#

Silence now 😂

static cove Aug 30, 2020, 2:31 PM

#

Creating a new window in pyqt5 should be relatively clean. You either create a new instance of the existing class or create a new class for the specific window

wise hearth Aug 30, 2020, 2:35 PM

#

.

#

nvm

#

I go find answer

#

on chrome

static cove Aug 30, 2020, 2:39 PM

#

@wise hearth you should be able to bind to <Button-1> to call a function when the left mouse button is pressed

#

Take a look at this page to see all the different bindings for tkinter https://effbot.org/tkinterbook/tkinter-events-and-bindings.htm

I have actionUsername button in the menu bar, but it doesn't support .clicked.connect() method py MainWindow.setStatusBar(self.statusbar) self.actionUsername = QtWidgets.QAction(MainWindow) self.actionUsername.setCheckable(False) self.actionUsername.setObjectName("actionUsername")

void bramble Aug 30, 2020, 3:12 PM

#

self.actionUsername.setCheckable(True)
?

@serene oriole actions don't have a .clicked signal, it should be .triggered

void bramble Aug 30, 2020, 3:14 PM

#

oh

#

of course

serene oriole Aug 30, 2020, 3:14 PM

#

@static cove thanks

#

is still very confusing to me

static cove Aug 30, 2020, 3:15 PM

#

Buttons have the clicked signal, Actions have triggered. It's a bit annoying *shrug emoji here*

serene oriole Aug 30, 2020, 3:15 PM

#

I mean in my head both are buttons, just on different places..

static cove Aug 30, 2020, 3:15 PM

#

Yeah. They behave slightly differently, but again, *shrug emoji*

#

But if you're talking about a menu, you can place Buttons there. Actions just fit better stylistically

serene oriole Aug 30, 2020, 3:16 PM

#

is there any other trigger action I should know?

#

or just clicked and triggered

static cove Aug 30, 2020, 3:17 PM

#

https://doc.qt.io/qt-5/qaction.html#public-slots Here are the available slots for a QAction. Looks like you can do hover and toggle as well

#

oh whoops, should've linked a section below. You want signals, not slots

serene oriole Aug 30, 2020, 3:17 PM

#

it doesnt even include clicked as a signal

#

what a mess

static cove Aug 30, 2020, 3:18 PM

#

but still, you have hovered(), changed(), and toggled()

#

Triggered would be the replacement for the clicked

#

I think it's specifically triggered and not clicked because they're trying to design it so that keyboard shortcuts can also activate the menu buttons, not just clicks

serene oriole Aug 30, 2020, 3:20 PM

#

how would I make the triggered action open another window that is inside another class?

static cove Aug 30, 2020, 3:20 PM

#

Well, assuming that the new window is already instanced and just needs to be shown. It would just call the .show() function on it

serene oriole Aug 30, 2020, 3:20 PM

#

I basically made MyApp class just to add event methods to it, but don't know how to connect another window to it

#

It's not instanced yet

📎 unknown.png

static cove Aug 30, 2020, 3:22 PM

#

While instantiating your MyApp class, I would make all children windows initialized too, but just not shown yet. Then the button functions would show them

#

Or you can have the button initialize it too, depends what you want to do

serene oriole Aug 30, 2020, 3:29 PM

#

@static cove I wrote this method, but on click it shows the window briefly and isntantly closes it without any errors

📎 unknown.png

static cove Aug 30, 2020, 3:46 PM

#

Probably because you're losing reference to it. As soon as the function ends it gets gc'd. You probably want to have some sort of variable in the MyApp class to hold the reference to that @serene oriole

serene oriole Aug 30, 2020, 4:07 PM

#

will try adding it as an attribute, thx

echo ruin Aug 30, 2020, 5:02 PM

#

I've got a QLineEdit set up, but my cursor goes behind it? is there a way to stop this or have I done something wrong

#

also @serene oriole I set up my __init__'s like this and it seemed to do the trick:

class MainWindow(QMainWindow):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)```

serene oriole Aug 30, 2020, 5:05 PM

#

@echo ruin I did it like this but it feels to janky to add it for every possible window/form

📎 unknown.png

echo ruin Aug 30, 2020, 5:07 PM

#

ya idk all the examples I've gone through set up the window with super().__init__()

serene oriole Aug 30, 2020, 5:13 PM

#

I am pretty new on oop, super().__init__() basically allows me to inherit from multiple other classes is that right?

#

could you show some more code @echo ruin ?

static cove Aug 30, 2020, 5:17 PM

#

super() will inherit from its parent class. With Qt it's necessary to make sure all functionality is behaving as expected

serene oriole Aug 30, 2020, 5:18 PM

#

but I don't understand how that is useful for what I am trying to do =/, seems like I should incorporate it in my code, but it doesn't solve the jankiness of having windows as attributes of main window

echo ruin Aug 30, 2020, 5:33 PM

#

every time you want a new window, you have to create a new instance of the window
class MainWindow(QMainWindow) by passing QMainWindow into your class + using super().__init__(), you're allowing your class to initialize QMainWindow and therefor create a new instance/window

#

I've got no clue what having parent in there does, but it fixed the issue where the window wouldn't stay open

#

also ya if you need to create a new window for every thing/form then you'll have to create a new instance every time @serene oriole

rocky dragon Aug 30, 2020, 5:38 PM

#

the parent makes the object keep the parent object alive by keeping a reference to it, if you don't do that it gets garbage collected by python which in turn does all the cleanup and possibly some invalid references by qt

echo ruin Aug 30, 2020, 5:44 PM

#

So if 2 calls to the qt window are made, without the parent, gc only allows the first instance of the class to stay?

serene oriole Aug 30, 2020, 6:24 PM

#

to be honest I am completely lost but I managed to fix it

You need to safe the reference of the image outside of the function. Otherwise the reference to the image gets garbage collected once the function ends and tkinter has nothing to display

not really what you're looking for

idk look it up

thanks, im sure i can chage it abit atleast i have smth to start from

#

on an unrelated note, I'm having trouble getting an image to display in the qt designer, I've tried importing it (png) as both a pixmap/icon but neither seems to display it/do anything
just gonna shimmy this down here

placid nebula Sep 2, 2020, 5:28 PM

#

'pyuic5' is not recognized as an internal or external command,
operable program or batch file.

#

anyone know how to deal with this?

Why isn't this giving the border radius to my tab?

plucky wedge Sep 2, 2020, 5:41 PM

#

why so many ppl use self , lke what does it change

vague gale Sep 2, 2020, 5:46 PM

#

@plucky wedge I'm working inside of a class, so for creating a class method we need to pass the self argument

twilit helm Sep 2, 2020, 6:48 PM

#

can anyone tell me how to get return value of a function called by button(tkinter button)???

vague gale Sep 2, 2020, 7:02 PM

#

@twilit helm I think you should implement that into your command function

twilit helm Sep 2, 2020, 7:04 PM

#

@twilit helm I think you should implement that into your command function
@vague gale how?

#

how to implement in command function

echo ruin Sep 2, 2020, 9:40 PM

#

@plucky wedge classes/oop allow you to do something like this:

class Window(something):
  def __init__(self):
    self.x = 50
    self.pos_x = 50
    message = self.setupThingy(pos_x)
    print(message,self.x)

  def setupThingy(self, pos):
    self.x += self.pos_x
    return "some string"```

#

so in the example, even if you don't return x, self.x allows you to modify x within the class

plucky wedge Sep 2, 2020, 9:42 PM

#

wait so if u have class and self will work like global for whole class?

echo ruin Sep 2, 2020, 9:42 PM

#

but in something like pyqt5, it allows you to do smth more along the lines of:

class StartWindow(QMainWindow):
    def __init__(self, parent=None):
        super(StartWindow ,self).__init__(parent)
        
        self.windowWidth = 200
        self.windowHeight = 200

        self.setGeometry(100, 100, self.windowWidth, self.windowHeight)
        self.initUI()
        self.show()
        
    def initUI(self):
        self.setStyleSheet("background-color: rgb(0,0,0);")
        self.setWindowTitle("Speeed")
        ...

#

within the scope of the class ya

#

it's basically another data structure that allows you to access values/functions without the added complexity

plucky wedge Sep 2, 2020, 9:44 PM

#

ohh ok i get it finally

#

thank you very much

echo ruin Sep 2, 2020, 9:45 PM

#

np, I actually avoided learning it up until like a month ago, but it's super useful in a lot of senarios

plucky wedge Sep 2, 2020, 9:45 PM

#

yea i tried to avoid it as much as possible as i didnt get it and couldnt find easy but efficient meaning for taht

#

2.5 months of coding while avoiding it

i would use that space for these buttons

subtle otter Sep 2, 2020, 10:58 PM

I would recommend using pyqt5 for whatever you want to do, tkinter wont make it look pretty

exotic dirge Sep 2, 2020, 11:02 PM

#

im on a deadline and i have never worked with tkinter or pyqt5 before

#

how hard would it be to do this in pyqt5?

#

how similar is pyqt5 to tkinter?

lapis pendant Sep 3, 2020, 1:20 AM

Here I am useing tkinter to make a basic text editor

I want my buttons organized in a toolbar for obvious reasons.

So I wrote the code shown and there dont seem to be any buttons in the program. No errors show up.

Sorry that these aren’t screenshots btw I am having other issues

Feel free to tag me if you have any ideas

digital rose Sep 3, 2020, 1:21 AM

#

@subtle otter I used mockplus

#

But I don’t know how to program it

#

Bc idt it has a program feature

subtle otter Sep 3, 2020, 10:53 AM

#

@exotic dirge pyqt5 has a ui designer if you use qt creator on windows

#

on linux systems, there's a lighter tool called qt designer which is only for building the ui, whereas creator is for both the c++/python code, and the UI

#

on windows you will need qt creator since qt designer is not available on it

bronze basin Sep 3, 2020, 10:55 AM

#

qt designer is there on windows?

#

with the pyside 2 installation you get it

#

or you can just download from the website

subtle otter Sep 3, 2020, 10:57 AM

#

oh

#

didn't know that

#

well all I can say is that qt5 boosted my workflow. I finished an app in about 2 days using it

#

https://github.com/skynse/packman

GitHub

Skynse/packman

Real time network usage monitor for Windows, Mac, and Linux - Skynse/packman

#

The fact that I could use qt designer made it even better, cause I could just convert from a .ui file to a .py file and use that code as the interface

#

@digital rose hehe, I remember when I used to make mockups without even adding functionality, check out qt designer/creator

bronze basin Sep 3, 2020, 11:12 AM

#

yup its very helpful and good

plush stream Sep 3, 2020, 12:23 PM

#

Does anyone know why my qt designer's ui looks so old like tkinter?

📎 Screenshot_56.png

#

I saw other people's qt designer and it looks far more modern

#

I'm on the newest version too, so idk what's happening here

subtle otter Sep 3, 2020, 12:26 PM

#

that's just what it looks like on windows I think

bronze basin Sep 3, 2020, 12:26 PM

#

nah

#

for me it looks a bit different

#

@plush stream try the pyside 2 version maybe?

#

if that doesnt do anything you got the latest one then

#

and it looks like its supposed to

plush stream Sep 3, 2020, 12:28 PM

#

I followed a tutorial from a YouTuber by by the name of Tech with Tim

subtle otter Sep 3, 2020, 12:28 PM

#

Mine looks like this but it's because of my system theme

📎 unknown.png

bronze basin Sep 3, 2020, 12:28 PM

#

yes

plush stream Sep 3, 2020, 12:28 PM

#

And he doesn't use anything related to pyside

bronze basin Sep 3, 2020, 12:28 PM

#

things can change due to your system theme

#

for me also it changes according to your system theme

plush stream Sep 3, 2020, 12:29 PM

#

I might try to restart

#

I use the window default theme btw

#

Nah, restarting doesn't work

bronze basin Sep 3, 2020, 12:30 PM

#

then it looks like its supposed to i guess

plush stream Sep 3, 2020, 12:37 PM

#

Yeah, it seems to be just the editor, the output window looks just like Windows 10 window

#

Though it's annoying that the preview in designer doesn't match up with the output window

subtle otter Sep 3, 2020, 1:43 PM

#

I mean, it does use the win32 api tho soo yeah

digital rose Sep 3, 2020, 1:59 PM

root = Tk()

checkedBox = IntVar()

for i in range(4):
    checkbox = Checkbutton(root, text=i, variable=checkedBox)
    checkbox.grid(row=i, column=0)

root.mainloop()```

#

why does checking one of these boxes tick all of them

#

:/

#

if i remove the variable=checkedBox it works fine but then i can't see if the boxes are checked or not

echo ruin Sep 3, 2020, 2:15 PM

#

@plush stream also the designer you're using isn't the full designer studio

plush stream Sep 3, 2020, 2:16 PM

#

Oh? I don't know it was different

#

Okay, thanks, i'll check it out

echo ruin Sep 3, 2020, 2:17 PM

#

but you can always get away with only using the qt designer too

plush stream Sep 3, 2020, 2:17 PM

#

Got it

echo ruin Sep 3, 2020, 2:19 PM

#

actually you might have to buy it, I haven't looked into it too much

plush stream Sep 3, 2020, 2:47 PM

#

I don't think so, it's open source

#

Also, since i'm new to pyqt, is it able to animate menus? So they'll have some sort of transition animation?

bronze basin Sep 3, 2020, 3:05 PM

#

yes

#

you can use qt designer itself for this

#

but you need to know css to do this(i think)

#

or use the QpropertyAnimate

#

not sure

plush stream Sep 3, 2020, 3:09 PM

#

Cool! I've been wanting to do that, couldn't do it with tkinter 😅

Hello, is there someone who programs on PyQt5 with vscode ?

bronze basin Sep 3, 2020, 3:27 PM

#

I do

#

though i use pyside 2 they both are almost identical

#

so ..

cinder grove Sep 3, 2020, 3:29 PM

#

i'm getting troubles with these errors idk why

📎 unknown.png

bronze basin Sep 3, 2020, 3:46 PM

#

@cinder grove i am pretty sure you have to do from PyQt5.QtCore import Qt

cinder grove Sep 3, 2020, 3:48 PM

#

@bronze basin not working :/

bronze basin Sep 3, 2020, 3:57 PM

#

from PySide2 import QtCore, QtGui, QtWidgets
from PySide2.QtCore import QCoreApplication, QPropertyAnimation, QDate, QDateTime, QMetaObject, QObject, QPoint, QRect, QSize, QTime, QUrl, Qt, QEvent

app = QApplication(sys.argv)
window = MainWindow()
window.show()
sys.exit(app.exec_())

#

@cinder grove this is how i would usually do mine

#

you can just replace the PySide2 with PyQt5

#

i am not exactly sure how you have done what you did maybe you didnt define smth properly?

#

you usually have to do this

class MainWindow(QMainWindow):

    def __init__(self, *args, **kwargs):
        super().__init__()
        your code here or whatever

#

or what i did

#

i have never seen someone do it by just calling a function without defining the MainWindow Class

cinder grove Sep 3, 2020, 4:03 PM

#

@bronze basin yes i know for the mainwindow class i just wanted to do a "fast test"
I will try to do it with PySide2 since i have both installed

#

what's the difference between pyqt and pyside ?

bronze basin Sep 3, 2020, 4:07 PM

#

Nothing much actually

#

main difference is the licensing

#

between both of them

#

everything you do with pyqt5 can be done just as well in pyside2 (to my knowledge)

cinder grove Sep 3, 2020, 4:13 PM

#

ok @bronze basin are you using vscode or pycharm ?

bronze basin Sep 3, 2020, 4:18 PM

cinder grove Sep 3, 2020, 4:18 PM

Im looking for a more advanced python library to create interfaces with other than tkinter, though easy to use, but I believe it is lacking visual power...

Anyone got any tips?

pyglet

#

really performant one

static cove Sep 4, 2020, 9:26 PM

#

@digital rose Commonly recommended ones are PyQt/Pyside2, Kivy, and WxPython. There are a few ones not used as often like the GTK bindings and a couple of others.

digital rose Sep 4, 2020, 9:27 PM

#

Yh i already checked a few

#

Though I am looking for like, “the next step” when it comes to interfaces

#

As background code aint the problem

#

Isn’t it a game engine rather?

#

Also pyqt is premium?

#

Also any downsides on using pyqt, Looks the most promising

static cove Sep 4, 2020, 9:45 PM

#

The biggest thing with pyqt is the licensing. PySide2 is an alternative binding of the Qt library and it's a LGPL license.

digital rose Sep 4, 2020, 10:43 PM

#

Is pyqt thhe only drag and drop interface builder? I like the concept? Also Ping gtg

mint needle Sep 5, 2020, 12:16 AM

Just to mention, there is a realy easy GUI module called DearPyGui it’s open source on github

Pyqt has a drag and drop program, Qt Designer. But I code all my UIs from scratch/dynamically

mint needle Sep 5, 2020, 12:19 AM

#

Pyqt, never heard of that!

#

time to have a quick google!

obtuse thistle Sep 5, 2020, 12:24 AM

#

I wouldn't think pyqt is that easy, but I also wouldn't know

#

kivy is easy enough once you learn kv lang

rocky dragon Sep 5, 2020, 12:36 AM

#

I think that no matter what you will find a drag and drop for, it just won't be sufficient for anything more complex; but can be useful for prototyping

How do i edit pyqt ui that i made inside qt designer? You see, i converted the format from .ui to .py and i already wrote my code inside that .py file, so how do i edit that ui like adding a button without rewriting the code that i wrote earlier?

solid aurora Sep 5, 2020, 1:16 AM

#

You can't. That's one of the downfalls of ui designers that produce the code

rocky dragon Sep 5, 2020, 1:29 AM

#

Usually what you'd do is separate the generated UI code through subclassing or something like that

plush stream Sep 5, 2020, 1:47 AM

#

Ah, well. I guess i'll use it for prototyping then, thanks for the answers!

maiden dragon Sep 5, 2020, 2:37 AM

if not no worries, its quite amazing but some things seems a little odd

rugged stratus Sep 5, 2020, 2:40 AM

#

Does anyone know if theres a way to yield to the PyQt5 event loop? I know there is the Timer capability in Qt, but its also seems to require a callback function. It's obviously livable but I was curious if I could just yield and wait for the event loop to cycle back to one of my loops.

@maiden dragon I haven't yet, but I'll probably check it out soon

maiden dragon Sep 5, 2020, 3:42 PM

#

making progress with it, really powerful stuff. should work well for my dynamic plotting

static cove Sep 5, 2020, 3:43 PM

#

@reef remnant Do you have code to read from the GPIO pins already? It shouldn't really matter which GUI framework you use unless you have very niche/odd data you need to visualize

reef remnant Sep 5, 2020, 3:44 PM

#

I don't have anything yet I'm waiting for my pi to arrive

#

but I've never done anything in python that is GUI related

static cove Sep 5, 2020, 3:45 PM

#

Well, I'd focus first and figuring out how to get data, looking at what the data looks like, and then seeing what's a good fit for visualizing it. tkinter + matplotlib is a common pairing. I personally prefer pyqt5/pyside2 + pyqtgraphs. mrpolymath above has mentioned wxpython + wxmplot. There are definitely options, it just depends on what kind of data you want to plot

#

Also, when you say "GUI for your rpi" are you going to have an external monitor connected to it or do you have like a touchscreen interface you plan to connect via GPIO?

#

But once you get it, feel free to ask here if you have specific questions for dealing with a GUI framework~

reef remnant Sep 5, 2020, 3:48 PM

#

I just need to read a data and print it out on a GUI I don't think I really need matplotlib tbh

#

Also, when you say "GUI for your rpi" are you going to have an external monitor connected to it or do you have like a touchscreen interface you plan to connect via GPIO?
@static cove I'm going to connect it to a PC monitor

static cove Sep 5, 2020, 3:49 PM

#

Well, it depends on the type of data. If you want to graph it you'll need a library that can graph. Matplotlib is the somewhat of the defacto standard for that (although I don't like it for dynamic and liveplotting data, it can be a pain to set it up correctly)

#

Then yeah, an rpi is just a microcomputer, so nothing special for getting it to display stuff necessarily.

#

Also feel free to ask questions with rpi in #microcontrollers

@static cove no need in a graph tbh, just the value which is probably a float and maybe a string I'm not sure yet

static cove Sep 5, 2020, 3:51 PM

#

Well, if you don't need it looking nice tkinter is probably the fastest since it's in the standard library.

reef remnant Sep 5, 2020, 3:51 PM

#

but I need smth to be beginner friendly

#

and not take too long to make 😅

static cove Sep 5, 2020, 3:52 PM

#

I'd recommend tkinter then. There's a few oddities but there are plenty of tkinter tutorials and people that have used tkinter.

reef remnant Sep 5, 2020, 3:52 PM

Hey @placid nebula!

Uh-oh! It looks like your message got zapped by our spam filter. We currently don't allow .txt attachments, so here are some tips to help you travel safely:

• If you attempted to send a message longer than 2000 characters, try shortening your message to fit within the character limit or use a pasting service (see below)

• If you tried to show someone your code, you can use codeblocks
(run !code-blocks in #bot-commands for more information) or use a pasting service like:

@placid nebula so, it runs first and only once. You probably want to use Pyqt's signal/slot method, so that when you check/uncheck checkBox_3 it'll adjust checkBox_13

shy nova Sep 6, 2020, 6:54 PM

#

I'm having the strangest issue with PyQt5:

#

I found a hello world example online that works

#

This code is at the end to run it:

#

if __name__ == "__main__":
    app = QApplication(sys.argv)
    mainWin = HelloWindow()
    mainWin.show()
    sys.exit( app.exec_() )

#

However, if I change that code to:```py
if name == "main":
app = QApplication(sys.argv)
HelloWindow().show()
sys.exit( app.exec_() )

#

the app fails to show up

#

Is this a garbage collection thing?

rocky dragon Sep 6, 2020, 6:56 PM

#

You need to keep a reference to the object you create or it gets deleted

shy nova Sep 6, 2020, 6:56 PM

#

I literally realized "oh prolly garbage collection" as I was typing that question up lmao

#

oop

#

never realized python's garbage collector is so aggressive

rocky dragon Sep 6, 2020, 6:56 PM

#

Without assigning, it's only needed until show ends and gets deleted by the time executing gets to the next line

#

Anything with its refcount at 0 should be collected immediately

shy nova Sep 6, 2020, 6:58 PM

#

Unrelated question, but why don't we need to explicitly pass app to mainWin or vice versa?

#

how does mainWin know what event loop to attach to?

#

or does PyQt5 only allow you to have one event loop?

#

@rocky dragon

rocky dragon Sep 6, 2020, 6:59 PM

#

They're bound to threads I believe

shy nova Sep 6, 2020, 6:59 PM

#

ah I see

#

I guess that makes sense because app.exec_() is blocking

static cove Sep 6, 2020, 7:06 PM

You would have to try to build that functionality yourself in tkinter unfortunately

placid nebula Sep 6, 2020, 7:07 PM

#

thats crap, wonder why they not extend functionality of tkinter

#

im trying to build same desktop app like i did in qt

#

but looking at tkinter it has its own limits

static cove Sep 6, 2020, 7:09 PM

#

tkinter is in the standard library so it's tied to the python release schedule, but I also don't think it's received any sort of update in a long while. It makes it stable, but tkinter does have fairly limited functionality compared to other frameworks

placid nebula Sep 6, 2020, 7:09 PM

#

im beginner at python but looking on structure i like more tkinter's than qts

#

maybe because qt code generated from designer looks so messy

#

in your opinion i should stick to the tkinter or work on qt?

static cove Sep 6, 2020, 7:11 PM

#

You don't have to use designer, you can code it yourself. But with Qt styling it can certainly add some line lengths. Same with tkinter though. I have a preference for pyqt/pyside2, but it depends on your ultimate goal. If it's just learning then tkinter isn't bad.

placid nebula Sep 6, 2020, 7:12 PM

#

well im on the beginning and would like to know most used frameworks that may help to get job in a year...

rocky dragon Sep 6, 2020, 7:13 PM

#

The main loop is a bit different since it's bound to the gui thread, but otherwise you can have events loops for every QThread you make

static cove Sep 6, 2020, 7:13 PM

#

Well, honestly for getting a job, desktop apps (especially in python) are a bit niche. Web apps and web development is far more common.

placid nebula Sep 6, 2020, 7:13 PM

#

django right?

#

would You be so kind to let me know few frameworks that i could study hard for next year?

I'm getting to rewriting the gui of my older project. For example here https://github.com/Numerlor/Auto_Neutron/blob/dev/auto_neutron/popups.py#L340, what would be the usual way of separating the logic from the UI code? Just subclass the UI code and implement logic on top of it?

shy nova Sep 7, 2020, 12:36 AM

#

How should I split up a PyQt5 app into python modules?

#

I'm thinking:

#

__main__.py:```py
import sys
from gui import App

if name == "main":
sys.exit(App(sys.argv).exec())```

#

gui.py: ```py

imports

class MainWindow(QMainWindow):
def init(self):
QMainWindow.init(self)
# UI code

class App(QApplication):
def init(self, argv):
QApplication.init(self, argv)
self.window = MainWindow()
self.window.show()

#

Should I split gui into multiple python files in a gui module, one for each component?

#

is there something else I should change?

sudden coral Sep 7, 2020, 2:24 AM

#

Generally, I like to keep different windows/widget implementation in separate modules. An exception is when they're short and closely related to each other.

#

@shy nova

#

Having the app next to the main window is fine I suppose, since they are indeed related and the app seems to not have much code. In fact, you don't really need to subclass the app. It could just be implemented as a function to create an app, create a main window, and show the window.

trim ibex Sep 7, 2020, 2:49 AM

#

put as many bells and whistles in your subclass as you can to make things easier; there's a lot of dumb stuff and things that could be greatly improved

#

btw a good way to think of it is keep all of this stuff out of your main https://i.imgur.com/0KhjZJB.png

Hello, I wanted to create a WebApp using Python CGI, using which i can open a graphical applications inside the browser itself by just writing the application name. Can someone help me in that.

shy nova Sep 7, 2020, 5:21 AM

#

@rancid tusk so you want to create a launcher in a browser? Difficult but doable. Likely not connected to CGI unless you're not explaining something though.

#

on windows, you can js window.location = "calculator://" and it will either offer to launch calculator or open it anyway depending on the browser

#

with linux, I believe you need a mime type instead of a url scheme, but idrk

#

and I have zero clue about macos

rancid tusk Sep 7, 2020, 5:24 AM

#

@shy nova i am explaining my use case a bit .
I have a linux system where my webserver is working, and in that i have created my webApp usignPython cgi.
I have a created the webApp in such a way so that if i enter any linux command like date, cal it shows the output in the browser. Similarly if i give gedit, or firefox command it should open the specific application in the browser itself as if a client is using the webapp and wants Firefox to be opened.

shy nova Sep 7, 2020, 5:26 AM

#

I have a created the webApp in such a way so that if i enter any linux command like date, cal it shows the output in the browser
Ok, this makes sense. I remember doing something similar 5 years ago in JSP back in middle school 🙂

#

Similarly if i give gedit, or firefox command it should open the specific application in the browser itself as if a client is using the webapp and wants Firefox to be opened.
Explain this a bit better

#

so let's call the two machines Server and Desktop for now

#

When you type gedit, do you want the gedit window to show up on Server or Desktop's gui? @rancid tusk

#

if the former, set the environment variable DISPLAY to :0 (or some other digit if you run your x11 server on a nonstandard display number)

#

if the latter, you'll want to set up ssh forwarding or NoVNC

sudden coral Sep 7, 2020, 5:41 AM

#

To me, it sounds like they want the requested application to run on the server but render and be interactable through the client's browser.

#

If that's correct, I don't think that's impossible, but I'm not sure how to accomplish that.

#

In any case, it doesn't sound very secure if clients can execute arbitrary apps on the server.

anyone know how to write a function that can clear frames in tkinter?

trim ibex Sep 8, 2020, 12:00 AM

#

i think a good way to do it is to subclass all your widgets and add functionality where the containers keep track of what's placed on them, and make a method to remove it where it automatically gets rid of the child widgets

#

so like when you add a widget to a frame you'd use a method on the frame itself, and another to remove the frame (or just clear it if you want it blank)

PyQt is licensed under the GPL so you need a GPL compatible license to avoid paying for a commercial license.

PySide2 is licensed under LGPL I believe, which is more lenient. I don't know the specifics unfortunately.

I am trying to use Kivy with Pycharm but I can't get a preview of my app no matter what I do. I have kivy and the dependencies installed but all I get is console output. No image or label. Am I missing a simple fix?
