@signal matrix well yeah i mean stored data in sqlite u can read it and print it

signal matrix Aug 31, 2018, 1:48 AM

well, can I apply it into the gui?

and display the data in a table?

Hello! Is it possible to get GTK (more specifically pango) on 32bit Windows without msys2?

(unless there's another way to show non-ASCII characters in cairo with font fallback, which is what I want to achieve)

TL;DR I have images in my .qrc resource file but for whatever reason they are visible in Qt Designer but not loading when I run main.py from windows powershell

tawny gust Aug 31, 2018, 7:50 PM

iirc, you have to load resources from a file manually

placid tapir Aug 31, 2018, 7:51 PM

#

where can I look up usage for that? Or do you happen to know the command to import .qrc off hand?

tawny gust Aug 31, 2018, 7:54 PM

u dont import it directly

you need to load the specific resource

fallen oxide Sep 1, 2018, 11:42 AM

#

What you're looking for is called a terminal emulator

#

But do you really need a bash prompt? You seem to just want the output from your bot

#

Which you could easily just use a textarea for

light turtle Sep 1, 2018, 11:43 AM

#

idk the output is live

fallen oxide Sep 1, 2018, 11:43 AM

#

So? Update the textarea :P

light turtle Sep 1, 2018, 11:44 AM

#

how would i get the output from the bot

#

when i print or something?

fallen oxide Sep 1, 2018, 11:44 AM

#

That depends entirely on how the bot is run

#

You probably don't want the gui to be part of the bot though

light turtle Sep 1, 2018, 11:45 AM

#

nah i just want to make it because i was bored

fallen oxide Sep 1, 2018, 11:45 AM

#

It'd make more sense for the gui to be separate and use the subprocess module for running the bot

#

You may need a thread, you may not

#

You'll have to play with it

light turtle Sep 1, 2018, 11:45 AM

#

the bot is a discord bot

fallen oxide Sep 1, 2018, 11:45 AM

#

Yes, you said that

light turtle Sep 1, 2018, 11:45 AM

#

idk if that makes a difference

#

oh

#

oops xD

fallen oxide Sep 1, 2018, 11:46 AM

#

Why would it? It's just a subprocess :P

#

That approach world work for anything that outputs to stderr or stdout

light turtle Sep 1, 2018, 11:47 AM

#

im kinda new to UI so if i print() how do i make that text go to a textbox?

#

or do i need to do something special instead of printing?

fallen oxide Sep 1, 2018, 11:47 AM

#

Again, that entirely depends on how you run the bot

#

If you're using subprocess, it has these pipe objects

#

You should read up on the subprocess module

@fallen oxide treeview of tkinter.

Are graphics with python even worth it? Seems like you can do very limited things with it

You can do anything with it, it's just.. slower

tawny gust Sep 2, 2018, 4:47 PM

not limited, just slow

hollow forge Sep 2, 2018, 8:31 PM

@tawny gust why is that btw?

cuz python is high level from computer right

or other reasons

tawny gust Sep 2, 2018, 8:50 PM

why is what?

why is it not limited? why is it slow?

placid tapir Sep 2, 2018, 10:04 PM

#

why is it slow

tawny gust Sep 2, 2018, 10:12 PM

#

Im assuming he meant 3d graphics, but this does sorta apply to anything

#

python is dynamically typed and garbage collected

#

it uses a lot more of the computer's resources than a lower-level language you would commonly use for graphics

yeah thats what i meant

And, when putting it to exe with cx_freeze, can I share the build dir with my friends, so they can download the app?

I mean will it work? or do they need python?

charred thunder Sep 3, 2018, 3:47 PM

#

if you compile it to a standalone executable, they should be able to run it without a python interpreter installed.

@hollow forge

hollow forge Sep 3, 2018, 3:48 PM

obsidian lance Sep 3, 2018, 3:55 PM

#

@hollow forge with tkinter you can make exe uses pyinstaller myscript.py --onefile --noconsole too... and it will work without any add on lot of machines with same os type (linux need compile exe for each version inside these versions environment, or can not run properly). But additional libs and files need experienced actions that result be as mono exe file

tawny gust Sep 3, 2018, 4:53 PM

#

linux doesn't use exes

drifting sundial Sep 3, 2018, 6:25 PM

#

You can run PyInstaller on Linux and it'll make the appropriate bundle though

#

So you just have to run it 3 times, once for each platform, and you're in business for a release

obsidian lance Sep 3, 2018, 6:28 PM

#

@tawny gust it can uses wine... just install wine uses apt , and after complete, double click exe. No guarantee but often app will start and work

#

but pyinstaller create executable for linux without .exe on end , if you about it

tawny gust Sep 3, 2018, 6:29 PM

#

wine isn't perfect

#

i cannot imagine a situation where i would ever want to run a python program in wine

i dont have apt tho

obsidian lance Sep 3, 2018, 6:30 PM

i use it for formatfactory and FileOptimizer ... the gui of FO work good , but FF have glitches

thanks guys

#

@obsidian lance @drifting sundial so on windows, i just have to install pyinstaller, and run the command into command line, right, nothing more?

drifting sundial Sep 3, 2018, 7:34 PM

#

Generally, yes @hollow forge

#

You should follow the instructions on PyInstaller's website

#

k, thx

drifting sundial Sep 3, 2018, 7:35 PM

https://pyinstaller.readthedocs.io/en/v3.3.1/usage.html

It really depends on your script

#

If it's simple, then yes, that should be all

hollow forge Sep 3, 2018, 7:45 PM

@drifting sundial worked

#

but as its not finished on coding

#

and i'll continue editing script

#

what coulld make it not "simple"

#

what are the Known Errors?

#

rip humor

#

and concerning the exe file, do it need other files, or i can just send the single .exe file to my friends

drifting sundial Sep 3, 2018, 7:50 PM

#

finger_gun

#

If you use --onefile, it will be a single file you can send to your friends

hollow forge Sep 3, 2018, 7:51 PM

#

cool

drifting sundial Sep 3, 2018, 7:51 PM

#

What would make it "not simple" are some package dependencies (Third-party libraries, like scrapy, etc.), any compiled portions (C-python API, etc.), application resources (e.g. files it needs to read), etc.

hollow forge Sep 3, 2018, 7:52 PM

it actually uses youtube_dl, and urlib and PIL

and some builtins ones

but it works

inland path Sep 4, 2018, 3:26 AM

Heya all! This is probably something that is asked daily, but I'm really struggling to choose a gui toolkit.
My goal is to create something similar to:

#

Realtimeboard
site: (https://realtimeboard.com/)
image: (https://ga1.imgix.net/screenshot/o/91635-1427188847-155298?ixlib=rb-1.0.0&ch=Width%2CDPR&auto=format)
RealtimeBoard is an Infinite canvas and whiteboarding platform that allows your team ideate, visualize and share ideas without any boundaries — think outside formats using your favorite tools and media.
Reactivepad
site: (https://reactivepad.com)
image (gif): (https://ph-files.imgix.net/a677f0dc-5bc8-4921-9658-76778bf1e81b?auto=format&auto=compress&codec=mozjpeg&cs=strip)
Reactivepad is an online collaborative document editor that lets you put calculations directly inside your textual narrative - think of MS Word and MS Excel combined. It allows to create truly smart and reactive data-driven documents that are almost like apps!
Quip
site: (https://quip.com)
image: (https://d2.alternativeto.net/dist/s/quip_328325_full.png?format=jpg&width=1600&height=1600&mode=min&upscale=false)
Quip is a collaborative productivity software suite for mobile and the Web. It allows groups of people to create and edit documents and spreadsheets as a group

#

Zenkit
site: (https://zenkit.com)
image: (https://cdn.zapier.com/storage/photos/81c777f29c63116baf20c50a283878a7.png)
A platform for collaboration and project management.
Coda.io
site: (https://coda.io)
image (looping video on their site, but close enough): (https://d33wubrfki0l68.cloudfront.net/444fa5c4260c3594514d21dee4dea21532d7746f/aebc8/welcome-assets/images/video-words-data.mp4)
No more ping-ponging between spreadsheets and docs. Coda keeps all your words and data in one place. With customizable views, your Trello-loving designer and Gantt-head PM can work off the same data. Coda docs start simple but have infinite room to grow. Think Minecraft for docs.
Notion
site(https://www.notion.so/)
image: (http://nicelydone.club/wp-content/uploads/2016/08/nicelydone-notion-list.jpeg)
A new tool that blends your everyday work apps into one. It's the all-in-one workspace for you and your team.

If needed, I can remove the junk and keep just the names.

aww hehe, that's ok! Thanks for the tip 😺

tawny gust Sep 4, 2018, 1:00 PM

#

@inland path I'm assuming you don't want to make a website?

#

If not, then Qt/PySide would probably be your best bet

inland path Sep 4, 2018, 1:01 PM

#

Yeah. I'd love a native app

#

Hmm, the only thing that worries me about Qt is that it's not open source

#

well, kinda.

#

https://i.ytimg.com/vi/0oZloMbnsMI/maxresdefault.jpg
this is a "thing" that also is kinda what I'd like to make...

#

having the ability to draw graphics as well as simple primitives (text input, etc)

tawny gust Sep 4, 2018, 1:04 PM

#

oh you want a circuit sim?

#

qt can do that with opengl

inland path Sep 4, 2018, 1:04 PM

#

Lemme explain, sorry 😅

#

Wait actually, can you go into more depth about opengl?

tawny gust Sep 4, 2018, 1:05 PM

#

Qt uses the GPLv3 license

inland path Sep 4, 2018, 1:05 PM

#

Oh, yeah, my bad

tawny gust Sep 4, 2018, 1:06 PM

#

Not really, I've not used it. I just know that you can make a QOpenGLWidget and use opengl in that

inland path Sep 4, 2018, 1:06 PM

#

Okay! Thanks. Do you know anything about, hmm.. I was thinking along the lines of pygame to make a custom ui, although that would be a pain to construct simple widgets.

tawny gust Sep 4, 2018, 1:07 PM

#

pygame? why?

inland path Sep 4, 2018, 1:11 PM

#

or something similar...
that kind of workflow sounds the best to me:
drawing stuff, kinda like how html works, instead of overriding and messing around with creating custom widgets for whatever library.
also, having one system so the entire ui can be made in one library, instead of restricting a part of the workspace to opengl/etc.

E.g. I want to make a simple custom widget. (lets say a graph, that is not included in qt or something, just an example) with pygame, I can write to the pixels directly, blah blah. with qt/other gui frameworks you have to faff around with overriding methods, and trying to make stuff work

E.g. Opengl does not have text inputs with copy/paste, etc, etc.
Putting an opengl widget inside a qt window allows qt widgets, but only outside the opengl frame.

tawny gust Sep 4, 2018, 1:14 PM

#

pretty sure you can overlay other widgets on top

inland path Sep 4, 2018, 1:16 PM

#

Yes, of course. It just seems... "simpler" to me, to have one unified system. I'm thinking either having an opengl widget inside a frame from another library, qt/etc, or just plain opengl. Is there something... better than opengl? something else I should use? Panda3D or something? Ogre? idek.

tawny gust Sep 4, 2018, 1:17 PM

#

dunno

#

3d isnt my area

inland path Sep 4, 2018, 1:18 PM

#

All good, all good! Thanks for the input though! I'll start with opengl, and see if any one else replies here 😛

wind birch Sep 4, 2018, 5:09 PM

#

One thing about QT is it requires a quite expensive commercial license.

tawny gust Sep 4, 2018, 5:15 PM

#

@wind birch for commercial use, yes

#

not for personal/free

#

if you make money off of it, they want their cut

wind birch Sep 4, 2018, 5:17 PM

re PySide2 framemless hint and constructing a custom titlebar

bleak smelt Sep 9, 2018, 1:14 AM

#

@placid tapir for my GUI, I set the window flags with .setWindowFlags(QtCore.Qt.FramelessWindowHint), then I created a qwidget at the very top of the gui, that included my app's icon, app name and with a horizontal spacer to push the exit and minimize buttons to the far right. I used a flat push button for min and exit. I use QT Designer for constructing my GUI.

#

Here is a screenshot

📎 unknown.png

#

📎 unknown.png

#

Then, with some css styling, I have the buttons with no border and a background change when hovering over the exit

did you modify the flags in QtDesigner?

#

or

#

I'm inheriting my ui into my main file that I'm dumping my functions into.. Also, the main.py is what I run first, it will load the ui and i just set signals and slots via __init__

if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    win = appMain()
    win.setWindowFlags(QtCore.Qt.FramelessWindowHint)
    win.setStyleSheet(active_css)
    win.show()
    sys.exit(app.exec_())

placid tapir Sep 9, 2018, 1:22 AM

#

ah ok

#

thank you that helps a lot

bleak smelt Sep 9, 2018, 1:22 AM

#

anything else, let me know.. I've been shoving my face in pyqt for months now

placid tapir Sep 9, 2018, 1:50 AM

#

So I might be building my application wrong in Python, potentially. I design the UI with QtDesigner and then I was creating a form with QObject QApplication

#

class loginwindow(QObject):

    def __init__(self, ui_file, parent=None):
        super(loginwindow, self).__init__(parent)

        self.call = self
        self.ui_file = QFile(ui_file)
        self.ui_file.open(QFile.ReadOnly)
        loader = QUiLoader()
        self.window = loader.load(self.ui_file)
        self.ui_file.close()
        self.USERinput = self.window.findChild(QLineEdit, 'USERinput')
        self.sudpwinput = self.window.findChild(QLineEdit, 'sudpwinput')
...
...

#

example

#

then

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)

    form = loginwindow('cryptokeeperlogin.ui')
    sys.exit(app.exec_())```

#

if I substitute app for win in your example it doesnt work because `AttributeError: 'PySide2.QtWidgets.QApplication' object has no attribute 'setWindowFlags'

#

Ill do some more digging! haha

bleak smelt Sep 9, 2018, 2:04 AM

#

here is how mine is configured.

#

from appui import Ui_App

class appMain(QtWidgets.QMainWindow, Ui_App):

    def __init__(self, parent=None):
        QtWidgets.QMainWindow.__init__(self, parent)
        self.setupUi(self)

if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    win = appMain()
    win.setWindowFlags(QtCore.Qt.FramelessWindowHint)
    win.setStyleSheet(active_css)
    win.show()
    sys.exit(app.exec_())

#

first thing you'll need to do is convert your .ui file into a python file

#

you can do that with pyuic

placid tapir Sep 9, 2018, 2:06 AM

#

yeah I was skipping that step with QUiLoader, but I can do it if I have to haha

bleak smelt Sep 9, 2018, 2:06 AM

#

i'd recommend it

placid tapir Sep 9, 2018, 2:06 AM

#

from my understanding QUiLoader basically just uses pyuic but itd probably be good to have an easily viewable UI in .py form

bleak smelt Sep 9, 2018, 2:07 AM

#

it helped me tremendously understand interactions with the widgets

#

recognizing how the methods are called on the widgets, and so forth.

placid tapir Sep 9, 2018, 2:08 AM

#

yeah, ill do that I think and comb through it then plug it in

bleak smelt Sep 9, 2018, 2:09 AM

#

I use PyQt versus PySide, so your convert string may differ.. but, my convert string looks like this python -m PyQt5.uic.pyuic c:\test\app.ui -o c:\test\appui.py

#

I'm on windows, btw.

hollow forge Sep 9, 2018, 1:52 PM

#

i'm having a pb

#

with pyinstaller

#

I guess ffmpeg is causing it*

#

is there a way to include packages?

placid tapir Sep 9, 2018, 2:24 PM

#

@bleak smelt I got the windowframelesshint working. Thanks a ton! I knew that it wouldnt be able to resize, but I am unable to move it at all now? Is that normal?

bleak smelt Sep 9, 2018, 3:12 PM

#

@placid tapir yeah, you need to have a specific widget pick up mouseevents, here is my example

#

def __init__(self, parent=None):
    self.oldPos = self.pos()

 def mousePressEvent(self, event):

     if self.titlebar.underMouse():
         self.oldPos = event.globalPos()
     else:
         pass

 def mouseMoveEvent(self, event):

      if self.titlebar.underMouse():
          delta = QtCore.QPoint(event.globalPos() - self.oldPos)
          self.move(self.x() + delta.x(), self.y() + delta.y())
          self.oldPos = event.globalPos()
      else:
          pass

#

so, i named my widget at the top as titlebar

#

@hollow forge I'd recommend making a .spec file. .spec file you can specify what packages to include and it will pull them in when you create your executable

hollow forge Sep 9, 2018, 4:26 PM

#

@bleak smelt hmm sure, thanks, but could u help me making that

#

i have no idea of what code to put in the .spec stuff

#

plus, I don't even know the package location as another module was responsible for this package download

bleak smelt Sep 9, 2018, 4:46 PM

#

Easy way to get a .spec is to just run pyinstaller on your main py file, it will spit out a .spec file, delete the exec it created, and edit your spec file

#

Then, with your spec file open, you should have a hiddenimports=[]

#

Here is my example hiddenimports=["PyQt5.sip", "QtGui", "QtWidgets", "pyperclip", "webbrowser", "csv", "json", "time", "random", "os", "sys"],

hollow forge Sep 9, 2018, 4:47 PM

#

lemme read that

#

:p

#

@bleak smelt once i deleted the .exe and do the edit on the .spec it created

#

i run pyinstaller again

#

right?

bleak smelt Sep 9, 2018, 4:49 PM

#

nah

#

just edit the spec file to your liking

#

then when you run pyinstaller, you'll run it on your .spec

#

not your main py file

hollow forge Sep 9, 2018, 4:49 PM

#

k, but do i delete the first .exe created?

#

before re-running

bleak smelt Sep 9, 2018, 4:50 PM

#

yeah you can, i would

hollow forge Sep 9, 2018, 4:50 PM

#

k, thanks

#

i'll try

#

i'm not even sure why its not opening

#

but i guess its ffmpeg

bleak smelt Sep 9, 2018, 4:51 PM

#

just make sure you have that included in the hidden imports, also, if you have other py files your importing into your main, make sure you include them in the datas=[] area

hollow forge Sep 9, 2018, 4:51 PM

#

ooh

#

actually i have some 😛

#

k

bleak smelt Sep 9, 2018, 4:52 PM

@hollow forge make sure when you run pyinstaller, the spec file has the scripts included. also, make sure all your py files are in the same directory, if you elected to have '.' for the script itself.

is it possible to make a button transparent? to make a custom 'shaped' button like X but still the standard square button

#

im not finding any documentation on it

odd cypress Sep 10, 2018, 1:35 AM

What library are you using

placid tapir Sep 10, 2018, 1:36 AM

#

pyside2

#

pyqt basically

placid tapir Sep 10, 2018, 3:17 PM

#

Answering for anyone else maybe curious:
You can use transparent background images in buttons as opposed to conventional 'icon'.

example:

    self.createprofilebtn.setStyleSheet("QPushButton{background: url(:/images/prof.png); border: 0px solid black}" 
"QPushButton:hover{background: url(:/images/profpress.png); border 0px solid black}")

#

the border at 0 px seems to be necessary for the transparency to work, otherwise the button brings up a default 3D style behind your background image

So I'm currently working on a project with PyQt5 and I've been racking my brain with a problem for the past few days. I want to show a dialog, and when you click a button on that dialog I want it to close that dialog and open another one. What I've tried is for the onclick on the button I'm creating a QWidget, showing it, then closing the old one, but nothing else ever comes up. I can include everything I'm working with in a pastebin if you'd like to see more of what I mean.

placid tapir Sep 12, 2018, 3:15 PM

#

Put .show() in the init of the widget you are trying to make appear

#

Rather than in the call

lyric cave Sep 12, 2018, 3:26 PM

#

Are you creating it within the dialog which is being deleted? (Because then they both get deleted)

atomic socket Sep 12, 2018, 3:31 PM

#

Actually I may be doing that, how would I go about creating it outside of the dialog I'm deleting? I'm still somewhat new to QT and trying to learning it

#

I think I just figured it out

#

Heres a very brief version of what I've been doing:

from PyQt5.QtWidgets import QWidget, QApplication, QPushButton
import sys


class Widget1(QWidget):
    def __init__(self):
        super(Widget1, self).__init__()
        self.resize(300, 200)
        self.setWindowTitle('Widget1')
        self.button = QPushButton(self)
        self.button.setText('Spawn New Widget')
        self.button.clicked.connect(self.spawnNew)
        self.show()

    def spawnNew(self):
        # close the first widget, and create and show the second widget
        self.close()
        new = Widget2()


class Widget2(QWidget):
    def __init__(self):
        super(Widget2, self).__init__()
        self.setWindowTitle("I'm New!")
        self.show()


app = QApplication([])
one = Widget1()
sys.exit(app.exec_())

#

but I wasn't setting the new widget to self, so if I change

new = Widget2()

to

self.new = Widget2()

then everything works as expected, but if this isn't the proper way to accomplish what I'm wanting to do please let me know the correct way. Thanks for the help!

Awesome! I've implemented the solution into the actual project and everything is working smoothy.

#

Also, this is a bit off topic, but is there any benefit to making a desktop application when I could just make a web application that's already cross platform and accessible from any client?

haughty birch Sep 12, 2018, 5:10 PM

#

“Web client” as in online-only or as in built with something like Electron?

lyric cave Sep 12, 2018, 5:25 PM

#

Yes and no. There are two perspectives.

Developers:

Pro: Rapid redeployment (of pages and images and js). Rapid development (2 for the price of 1-ish).
Con: It's hell to figure out how an error occurred on any system because it could literally be running any combination of the 40 components you've added on top to show your web app which also changes underneath that and relies on unreliable infrastructure which you might be okay with because if it's down at all the whole thing doesn't work anyway.

Users:

Pro: There are basically never upgrades
Con: There are basically never upgrades. Software changes underneath them. Software cannot be reliably versioned. Software is now internet-style DRM'd and calls home. Software now exposes a much much larger attack surface, because all of the desktop software is exposed to exploit when SPOF is exploited.

How do I set a tkinter window to a certain size, and make it so it can't be expanded by the user?

atomic socket Sep 12, 2018, 5:37 PM

#

At least with QT I just set the minimumSize, maximumSize, and size to the same values. I'm not sure if there's an option to directly restrict resizing in TKinter but that may be the way to go.

#

Thanks @lyric cave for the input, still not sure which I'm wanting to go with though at this point. I feel like most end users would prefer a web application as opposed to desktop since desktop requires a lot more specifics and deployment, while web applications are (for the most part) more straightforward for end users to use.

#

I may need to sleep on it, I don't really want to put a ton of time into a project and realize at the end that it would be more accessible as a web app.

How do I make a tkinter window always on top?

lyric cave Sep 12, 2018, 5:44 PM

Just do an actual website application if you need maximum reach at lowest cost. Browsers exist on basically anything and everything, and if you never need to touch the user's filesystem/devices (or can do so through browser provided functions) then you can probably contain yourself quite easily.

Yeah there most likely are, and yeah AD uses LDAP under the hood, my backend for everything is just going to be ldap3 anyway, and it's also sort of like a personal challenge for me to make a project that I can use in the workplace instead of just an automation script that I write and rarely follow up on.

@bleak smelt pyqt probably has more up to date bindings seeing as they're updated much more regularly than pyside, however pyqt requires you to purchase a license if you go commercial, but pyside does not. It's a tradeoff

The difference is that pyqt is under GPL and pyside is under LGPL, personally I prefer LGPL for almost everything since it's more open source friendly than GPL imho.

atomic socket Sep 13, 2018, 3:46 PM

#

Yeah, but Qt is a pretty large organization and if you charge for using their software for free I'm sure they'd fight you for it

lyric cave Sep 13, 2018, 4:14 PM

#

GPL does require you to distribute the product with the licensed source code. It does not restrict you from charging for it, or offering services around it and being the main supporter/developer of it under your trademark.

LGPL isn't really more open-source friendly, it's more closed-source friendly. It allows you to link to LGPL code without the license being invasive (applying to the linking code). It lets you write closed source using LGPL (you must only include the source code of the LGPL code you're shipping).

It's not as if interacting with GPL code is necessarily going to be viral, though. There are plenty of proprietary/closed-source programs which are using the GPL linux kernel.

#

digs up an argument for GPL over LGPL

#

https://www.gnu.org/licenses/why-not-lgpl.en.html

#

I find this argument convincing around enforcing the availability of free software. Enforcing availability of software tools enables market entrants to make use of mature tools. A simpler and easier to enter market is always more likely to produce better products on the whole compared to the opposite.

@wet patio

Name your windowin a characteristic way for example: 'alamakota'

Use find_window('alamakota'),

With given handler use hide_from_taskbar(handler)

Last use set_topmost(handler)

Window is hidden from taskbar and it's alwoays on top.

I know it's not a beatyfull code, but works fine on windows XP and above.

if I .pack a frame in a window that is using .pack can I .grid the contents within the frame?

Im using tkinter

#

because I what my checkboxes to be aligned neatly but they are getting all crammed with .pack

@prime tangle I tried vim, but I just ended up going back to VSCode after a few months cause it never really caught on for me

Oh I wouldnt use it as an IDE personally @atomic socket

But for a general text editor in Nano

And using a vim emulator in VSC

General text editor as opposed to nano *

Right

and to be honest, I actually like nano

For what it is it does a great job

If possible to allow the central widget have the grips, to resize the window, change the cursor the corresponding cursor, and revert back. on the central widget or transparent qwidgets around the edges of the window.

I know resize can be achieved with c++. But, I couldn't find anyway to interact with Window DWM with python.

traceback

Please provide a full traceback to your exception in order for us to identify your issue.

A full traceback could look like: java Traceback (most recent call last): File "tiny", line 3, in do_something() File "tiny", line 2, in do_something a = 6 / 0 ZeroDivisionError: integer division or modulo by zero
The best way to read your traceback is bottom to top.
• Identify the exception raised (e.g. ZeroDivisonError)
• Make note of the line number, and navigate there in your program.
• Try to understand why the error occurred.

To read more about exceptions and errors, please refer to the official Python tutorial.

tkinter is multi-platform so whatever works on windows should work on linux etc.

charred thunder Sep 18, 2018, 7:06 PM

i don't really think so. i mean, if you were to start using external dependencies through pip then end users of your program would also have to install them, unless you package the application up into an executable file which... isn't recommended.

your root.mainloop() is essentially the exact same as doing ```py

winter vector Sep 18, 2018, 7:12 PM

do I need to remove it?

charred thunder Sep 18, 2018, 7:13 PM

#

well, it's causing your program to start updating the window before it's created the other widgets.

ah

#

I removed it, and now the window won't open 0^0

charred thunder Sep 18, 2018, 7:15 PM

#

yes, because you still need to start the main loop

#

the code you tried before essentially just gets stuck in an unbroken loop thanks to root.mainloop() and never reaches the code after that.

yes, there's been a big clusterfuck over the master/slave terminology recently.

#

wonder if tkinter's gonna change.

#

also, that error is referring to how you can't use both .grid() and .pack() in the same master.

#

choose one and stick to it.

Is there a good reason why I couldnt use a button as a 'label" I planned to swap images on

#

both would be using set stylesheet to change background image

#

button allows transparent images ontop of background image-using widgets

#

label cuts through it to solid color

winter gazelle Sep 18, 2018, 10:19 PM

#

In PyQt5, how would I go about routinely switching an image on a timer?

#

I can connect my timer timeout event to the image switcher, but everything else becomes unresponsive (e.g. buttons)

desert sapphire Sep 18, 2018, 10:24 PM

#

Are you using sleep?

#

Since sleep blocks the entire thread

winter gazelle Sep 18, 2018, 10:26 PM

#

Do I need to use multithreading for something like this?

#

I'm using a timer which sends the timeout event every second, not a call to time.sleep

desert sapphire Sep 18, 2018, 10:28 PM

#

I'm not familiar with Qt, but running the switching function in a different thread is worth a shot

winter gazelle Sep 18, 2018, 10:28 PM

#

Okay, I'll look into that

bleak smelt Sep 19, 2018, 12:00 AM

Anyone know with PyQt5, if its possible to extend one widget over top another?

Or is it possible to designate a specific area, for instance the edge of MainWindow, to accept mouse events, without needing a widget in place?

how can I fill a surface with transparent so that I can draw GUI things and blit it on the main display where is being rendered the game itself?

winter gazelle Sep 20, 2018, 8:39 PM

#

IIRC Pygame doesn't necessarily have layers. You just put everything in a render function, drawing the background first, and working your way forward.

fossil cipher Sep 20, 2018, 8:40 PM

@weak sapphire this looks like your question https://stackoverflow.com/questions/33630420/pygame-is-there-a-way-to-make-screen-layers

Stack Overflow

Pygame, is there a way to make "screen layers"?

I am working on a Tank game as a school project and I am trying to make it as user-friendly as possible (with things like customizable keybindings, display settings). However, I don't want the game

winter gazelle Sep 20, 2018, 8:40 PM

#

For a pseudo-layer system, you could split the render function into smaller functions:

def render():
    draw_sky()
    draw_level()
    draw_character()
    draw_gui()

weak sapphire Sep 20, 2018, 8:47 PM

#

I tried using Surfaces

#

but they don't support transparency

#

I think

fossil cipher Sep 20, 2018, 8:48 PM

the question seems to imply use of transparency

weak sapphire Sep 20, 2018, 8:48 PM

ofc

fossil cipher Sep 20, 2018, 8:49 PM

#

i mean on SO

#

using Surfaces

#

although perhaps not

#

i mean its basically the same as Eletrix's answer

#

you just dont draw where you want the lower layer to show through

weak sapphire Sep 20, 2018, 8:50 PM

#

I don't use sprites

#

the solution to the problem on stack overflow uses

#

and my program needs to popup a "window" showing stats of something when the mouse hovers something

#

I don't want to make 2 loops because that's unefficient

fossil cipher Sep 20, 2018, 8:54 PM

#

i'm afraid i'm useless for hover effects/tooltips (both come up fairly empty on search) in pygame

#

@winter gazelle any ideas?

winter gazelle Sep 20, 2018, 10:04 PM

#

You’d have to custom build a TextBox class with a draw method that puts text onto a surface, draws a rectangle based on the surface’s width and height, then renders the surface itself

#

Pygame is frustrating in that sense; you always have to make GUIs and there’s not much in the module to help with it

#

Why aren’t your surfaces transparent? I need to know a bit more about what you’re trying to draw to the screen

rustic sleet Sep 21, 2018, 4:19 AM

its actually using the open source Godot game

I use the built in godot UI components and gdscript language

which ends up letting you write python anything else the kernel supports in-game

I am trying to build a collectin of control nodes to let you create and execute workflows visually

its not really a visual programming language so much as a top-down architecture tool

I only have a few nodes now, a more or less standard linux terminal where you can shunt the output

#

a table/spreadsheet thing

#

and the big boy, the graphnode notebook

tawny gust Sep 21, 2018, 4:24 AM

what exactly is godot? is this graphical functionality builtin?

rustic sleet Sep 21, 2018, 4:25 AM

#

an an open source game engine with a python inspired scripting language, it has a large colllection of common game development nodes you can compose scenes with

#

it also lets you link libraries frm any language to projects

#

and there is a module to add python as a standard scripting lnaguage

#

yeah, it does 2d and 3d graphics very nicely

tawny gust Sep 21, 2018, 4:26 AM

oh, a game engine

rustic sleet Sep 21, 2018, 4:27 AM

yea, though I've been using it heavily for non-game applications

like this graph-based workflow system

that video shows a "clothesline" ui idea, where have windows hanging on a bar

#

which react to the user and environment

#

its meant to be more than just eyecandy

#

like by making windows require thier own physical space you can't "lose" them by stacking them up

#

and by doing a clothesline you can maintain a little of the "order" of a tiling window manager but still retrain some interactive freedom

tkinter is pretty dated, but I'm not sure it follows to abandon Python completely. There are decent UI frameworks in Python that aren't tkinter

bleak smelt Sep 24, 2018, 2:02 PM

#

@sage umbra I've been using PyQt for a few months, and I think its just fine. It comes with a designer that you can easily build your UI with.

sage umbra Sep 24, 2018, 2:03 PM

#

ok is that good for variable handling? @bleak smelt

#

like say i wanted to view a users profile using it would that be easy?

bleak smelt Sep 24, 2018, 2:05 PM

#

Depends on how you program it. You do have a lot of room with PyQt, turning widgets on an off, hiding them and so forth. You are able to easily swap widgets out for others .

I'm developing my first python App to sell, and running into some final issues. I used pyinstaller to generate a directory for redistribution, but it's 200 MB which seems quite large. It's probably because I decided to use pyforms (wraps anyqt, which wraps pyqt4) as my GUI. Pyforms has a lot of dependencies. Is this just the nature of GUI development with python? Should I retool it to use pyqt5 directly?

tawny gust Sep 24, 2018, 6:06 PM

Qt is large anyway

void oak Sep 24, 2018, 6:06 PM

That's what I wanted to know 😄 So it's probably not my little wrappers on top of things. How do y'all distribute QT apps? Just deal with the large file size?

#

I'll distribute the source for experienced people, who can run some command line installs, along with requirements.txt for pip, but it's the less experienced users I'm worried about.

#

As well as keeping hosting costs low.

tawny gust Sep 24, 2018, 6:35 PM

void oak Sep 24, 2018, 7:36 PM

I'm considering just going open source and accepting donations, but worried that I wouldn't make much. At least for a donation-only approach, distribution doesn't have to be super polished and a readme on github is good enough.

i've got a tkinter window for which i want to trigger a callback every time it gets moved/resized

#

all the examples i've seen have suggested:

self.bind('<Configure>', move_window)

#

but this event is only being triggered whenever the window is horizontally resized

#

it doesnt pick up movement or anything else

#

what am i missing?

#

im on Windows so maybe it's that?

#

nevermind, fixed it

You have to actually ask your question for people to help

#

!t ask

proven basinBOT Sep 25, 2018, 2:56 PM

#

ask

Asking good questions will yield a much higher chance of a quick response:

• Don't ask to ask your question, just go ahead and tell us your problem.
• Try to solve the problem on your own first, we're not going to write code for you.
• Show us the code you've tried and any errors or unexpected results it's giving
• Keep your patience while we're helping you.

You can find a much more detailed explanation on our website.

Hey guys, need help with a highlighting system for a calendar I'm building, kind of stuck, would appreciate 5 to 15 min of call or text

#

I used a for loop to create some Labels so they don't have unique identifiers, so the two options I've come up with are either re-designing it (not surer what I'd change, maybe create every Label individually? although that would be difficult because calendar / times change) or use Canvas to create a semi-transparent shape n place it on a grid behind the day I want highlighted or something

Forgrot to mention in Tkinter

placid tapir Sep 26, 2018, 7:12 PM

In lue of pyside2 native vertical tabs, would a solid way to make one be to use buttons on the left that hide/unhide stacked widgets?

when I say stacked widgets I mean actually stacked widgets not the QStackedWidget or whatever lol

if you wanted to make a big program with a UI - would you create the UI first and then the program around it or the program then the UI?

bleak smelt Sep 28, 2018, 9:35 PM

#

Thats your preference. If you're using PyQt, you can use the designer to create the ui, then you can start a new file to code the entire thing. If you don't want to use the designer you're welcome to code the entire app in one file.

haughty birch Sep 29, 2018, 2:45 AM

#

It’s probably going to end up being a little of both. You’ll want to at least mock up the UI for the functionality you have in mind and start writing the code around it, chances are your UI is going to change (probably significantly) as you actually use it for the task

Is PyQt very similar to Pyside2? @bleak smelt

bleak smelt Sep 29, 2018, 2:55 PM

@dense whale Yes. I've been using PyQt5 instead of Pyside. I read somewhere that there are more PyQt bindings for C, then Pyside has for PyQt. So, I just stuck with PyQt

dense whale Sep 29, 2018, 2:57 PM

#

I went with PySide because I heard that PyQT5 had a lot of licencing issues.

bleak smelt Sep 29, 2018, 2:59 PM

#

Possibly. I'd have to do some research on it myself. I'd put draft up what you want your GUI to do, and then research if PySide has all the bindings you need.. If you aren't doing some really extravagant, then you'll probably be just fine with PySide.

Hello, is there any functions I can call in Tkinter within a loop such as get_events() that would allow me to process events within a while loop so I can handle events and run a gameloop at the same time. Binding doesn't work for this since while loops prevent key binds from calling functions.

#

I'm in Python 2.7

fossil escarp Oct 1, 2018, 2:14 AM

#

Seriously, over 2000 people online and I've been waiting for almost half an hour, why?

odd cypress Oct 1, 2018, 2:19 AM

#

Because out of all the people online, most of them are either busy/away or aren't actively looking in the channel and most don't have the knowledge for your exact question

#

have you tried doing some research yourself while you waited?

fossil escarp Oct 1, 2018, 2:19 AM

#

Yes, no luck with research

odd cypress Oct 1, 2018, 2:19 AM

#

What exactly are you trying to do? You'll have much more luck getting help if you have a concrete example/problem you're working on

#

So it's easier for other to know what they can do for you

fossil escarp Oct 1, 2018, 2:21 AM

#

I'm trying to handle events and run a gameloop at the same time, at the moment, a loop blocks events from being handled and I'm wondering if it's possible to handle events within my while loop

odd cypress Oct 1, 2018, 2:22 AM

#

When I say concrete problem I mean mostly showing us some code.

fossil escarp Oct 1, 2018, 2:24 AM

#

I'm not working on a project as of this moment, I'm just trying to figure out how to do this, as of this moment I'm expirementing with anything I find to see if it works and I wrote something small to test anyhting I find. The idea is that a ball will move up or down a map, when you press "1" on your keyboard the ball will switch direction. from Tkinter import *
import time
global Movement
Movement = 1
YPos = 1
Map = Tk()
Map.title("Gameloop test")
Paint = Canvas(Map, width=300,height=300)
Paint.pack()
Paint.create_rectangle(0,0,300,300,fill="#00ff00",outline="#00ff00")
cha = Paint.create_oval(140,10,160,30,fill="#ff0000",outline="#ff0000")
while (True):
Paint.move(cha,0,YPos)
Map.update()
Map.update_idletasks()
event = event_queue.pop()
if (event.keysym == "1"):
Movement *= -1
time.sleep(.1)

#

I've tried key binds too, no luck

odd cypress Oct 1, 2018, 2:25 AM

#

Well from my quick research (sorry I'm not familiar with Tkinter,) it seems Tkinter's event system is built around the concept of binding functions to certain actions/widgets

#

http://effbot.org/tkinterbook/tkinter-events-and-bindings.htm

fossil escarp Oct 1, 2018, 2:26 AM

#

That's the problem I'm having, while loops block event bindings from working so if a user isn't providing constant update, the GUI freezes and this also makes it impossible to run a gameloop of any kind

odd cypress Oct 1, 2018, 2:26 AM

#

Have you tried running TKinter's loop

#

it provides a main loop

#

I don't think you're supposed to write your own like that

fossil escarp Oct 1, 2018, 2:27 AM

#

Mainloop blocks my gameloop from running

odd cypress Oct 1, 2018, 2:27 AM

#

Well if you want to run two loops then you'll probably need some Threading

#

(but I may be wrong, as I said, I know very little about TKinter)

fossil escarp Oct 1, 2018, 2:28 AM

#

From what I've heard, Tkinter doesn't play well with Threading

#

I'm not willing to test it

odd cypress Oct 1, 2018, 2:30 AM

#

Well if you're making a Game why not use an actual Game library like PyGame?

fossil escarp Oct 1, 2018, 2:32 AM

#

Because I have NO experiance with PyGame and I find that installing 3rd party modules is not very fun. Open Simplex was a nightmare, I'll look into PyGame if all else fails

#

Alright, I'm looking into PyGame

tawny gust Oct 1, 2018, 2:35 AM

#

you just use pip

#

its not like C, where you have to manually download and copy everything

fossil escarp Oct 1, 2018, 2:36 AM

#

pip?

odd cypress Oct 1, 2018, 2:38 AM

#

The default tool to download python packages

#

pip install pygame

#

boom you're done

fossil escarp Oct 1, 2018, 2:38 AM

#

ok

fossil escarp Oct 1, 2018, 2:57 AM

#

Pygame is failing me, the intro in the begginning is unacceptable for any program and the tutorial and the official page for pygame sucks, the example code they post doesn't run. Even when I try and corretc the error messgages, I'm going back to Tkinter and I'm going to spend forever trying to find out how to do something.

running into some tkinter issues

#

on the left the main window is the root Tk. on the right it's a Toplevel.

#

Dragging the mouse above the bars on the left works but it seems when the mouse enters the main window on the right the drag stops

#

note that there are two separate windows in each instance. the bars are in their own window floating below the main window. This is by choice because later on ill have them repositioning themselves over other places in the main window.

#

ah, self.wm_attributes('-topmost', 'true') solved it
