@lethal rain well, the program says that the HOST variable (as well as the PORT I suppose) are undeclared (unknown) inside the kv file.
usually you create and set these variables in a widget class or in the App, then access them in kv using self., root. or app.

anyone know if there is a way to view a crash report or an error message when pyqt5 crashes?

ok tried a new way

    def HOST(self):

        port = 8080

it shows main window but there is 0 text :/

that doesn't answer the question, unless the answer is No

lethal rain Sep 18, 2019, 9:17 AM

#

idk what you mean tho i put it in mainLabel class

alpine blaze Sep 18, 2019, 9:36 AM

#

i don't the host function called anywhere, MainLabel contains the conn id that host uses, that's good, but no use if host() is not called

tribal path Sep 18, 2019, 9:37 AM

#

error doesnt match those snippets btw

alpine blaze Sep 18, 2019, 9:47 AM

#

i guess there is no error now, just not the expected result either

#

which is totally normal if the host function is not called anywhere, the label is not going to be updated

#

you want to call it after the connection is done, i guess

lethal rain Sep 18, 2019, 3:59 PM

@alpine blaze i got it working

does subplot2grid not function with pyqt5

digital rose Sep 20, 2019, 10:19 PM

@worn viper

from kivy.core.window import Window
Window.size = (500, 300)
Window.borderless = True

#

but in the next step (I guess) you will want to create your own window title area
with ability to move kivy app window dragging it.
but such a window 'moving' will not be smooth, at least on Linux (it seems due to sdl)

2 solutions, either make sure the BoxLayout is exactly the width it needs to be, or add a Widget as the last children, that will take all the remaining space and push the previous widget to the left

candid eagle Sep 22, 2019, 11:56 AM

anyone used pyqt5? im editing on the desktop then pushing it to my git then pulling on to the pi

#

my issue is the text sizes are different on the pi compared to the pc side

#

also you may notice the tabs are overlapped by the Pause and Refresh Log buttons

#

not sure how i resolve this issue without making everything look out of place on the desktop side

rocky dragon Sep 22, 2019, 12:03 PM

#

are you using OS styles? that might be an issue

candid eagle Sep 22, 2019, 12:29 PM

i think so

#

new to all this so not 100% sure on anything lol

candid eagle Sep 22, 2019, 12:45 PM

okay so i tried QApplication::setStyle("windows");

#

but it didnt seem to do anything

i also tried QApplication::setStyle("fusion");

maybe i haven't set it right

could just add it to your python code

hmm but its c++ and no idea where to add it

solved where to change the style for the app but still hasnt done anything with the sizes

sudden coral Sep 22, 2019, 4:18 PM

#

Have you considered manually setting the font size and fontface?

#

It's probably not even the size that needs to change, just the font face

#

Some fonts look larger than others at the same size even

proper glade Sep 22, 2019, 4:31 PM

#

have you turned up the scaling setting?

candid eagle Sep 22, 2019, 4:33 PM

#

havent touched any scale settings that i can think of

#

tried changing the font

#

it changed it pc side so i readjusted then pushed it to the Pi and buttons still overlap

im currently looking into kivy as i was hoping to make an app that will work across PC, Rpi, Android

#

but i cant even get the same scripts to run in pycharm but i probably havent set it up properly

alpine blaze Sep 22, 2019, 10:35 PM

#

probably yes, have you made sure you use the same python in pycharm as the one you install kivy for? @candid eagle

#

(can you run the kivy app from command line for a start?)

i don't know how up to date this is, as i don't use pycharm, but maybe this helps? https://github.com/kivy/kivy/wiki/Setting-Up-Kivy-with-various-popular-IDE's

well, i just installed pycharm trial, and recorded myself starting a new project and running kivy in it, i had to look around a bit so it took a few minutes, but just the time to compress the video, and i'll be able to share it

(obs produces a 100MB file, and i know ffmpeg will convert it to something like 10MB)

i though i had a valid license that they shared to us kivy devs, but apparently that expired in 2015, didn't think it was that far back 😆 never used it

Not yet.
But I'm sure it’s only a matter of time. In any case, I would advise to take a closer look at this framework as well

What framework? Sorry I'm a complete beginner to all this so dont know all the jargon etc

@candid eagle I mean kivy framework:)

alpine blaze Sep 23, 2019, 9:36 AM

#

yeah, don't use designer, it's broken and nobody is working on it

#

people who learn to use kivy, and especially kvlang seems not to see a lot of need for a designer after a while

(visual studio ≠ visual studio code btw, and to build cpython extensions, you need visual studio, but outside that, you probably don't)

alpine blaze Sep 24, 2019, 12:03 AM

#

i don't think pysimplegui has a designer, or that it can easily replicate the previously described interface

#

but anyway

#

designers give a false impression of ease

#

also there are no rules against people pm-ing each others if they agree, the rule is not to pm people without authorisation, or to ask them to help in PM.

candid eagle Sep 24, 2019, 1:32 AM

no matter

#

im trying to press on with qt but i know its going to be a headache down the line

#

especially when i try get my app to android lol

alpine blaze Sep 24, 2019, 9:40 AM

#

uh, yeah, kivy would certainly be easier for that

#

anyway, if you want to avoid as much headache as possible, make sure to split clearly between app logic and interface, usually by putting the app logic into a library that can be used separately, and having the interface just call functions or classes from it.

#

this way you can scrub the interface any time without losing too much work

candid eagle Sep 24, 2019, 5:41 PM

#

yeah i plan on doing that on a rewrite as ill be hosting a server on the rpi to store any data and logic, then a client with the gui to read and edit the data stored on the server

thats the plan anyway

Does kivy have a tkinter like style?

digital rose Sep 25, 2019, 6:40 PM

#

if you mean the native appearance of widgets, then no, kivy does not have this. The idea is that you create apps that look the same on all platforms.

although of course, you can recreate almost any interface (if you have some skills)
@sudden wraith

hi everyone - is it a good idea to make desktop applications with pyQT? pros/cons?

#

how's the support for pySimpleGUI?

#

better to stick to PyQT or should I switch to PySimpleGUI?

robust marsh Sep 27, 2019, 12:20 PM

#

Hi all, i start python (as sysadmin and for personnal tests at home). I start on debian with python3 packages on the system (alonside the python2).
I've installed vscode + python plugins (python, pylint, intellisense)

#

since yesterday i look severals website to guess how to have a nice workflow for first tutos and real work after.
i've seen most speak about scaffold, virtualenv pytest/unittest (?),... i understand virtualenv will be a mandatory as i plan to use gitlab and CI (maybe with a docker runner) to add tests.

#

but starting with virtualenv, seems that every website/blog/tuto describe a different content, method, tools to mùanage them .. i'm totally lost 🙂

#

Current state : debian10, from apt packages python v2.7.16 and python3 v3.7.3, added apt packages : some modules like numpy, and python3-virtualenv (pip not installed), + vscode

alpine blaze Sep 27, 2019, 12:37 PM

#

hello, i'm not sure why that question is in #user-interfaces, did i miss something specific? Unless that's because of the usage of vscode? here is more about using python to build user interfaces.

#

but it's normal to be a bit lost, that's a lot to process at first, virtualenv is always a good idea, though not really mandatory especially if you already isolate things in docker, but it never really hurts anyway.

#

if you do python3 (and you should) you can managed them with the venv module of python, or you can still install virtualenv and work with that

#

but on debian, you have a few more hoops to jump through, as they removed it pip and virtualenv by default, which doesn't make sense to me, but whatever, it's easy to fix

#

it's nice to use higher level things to manage your venvs, historicaly things like virtualenvwrapper have been used, and can still be used, but more recently tools like pipenv and poetry have appeared to take a broader scope of project management, it's hard to say at this point if they are here to stay, but there is definitely some adoption of them, so they might, i'm not fully converted, and i use a more classical wrapper for my shell, but you can try various ways and see what's best for you, it's a lively space.

#

@robust marsh

robust marsh Sep 27, 2019, 12:43 PM

#

yes i put it because venv can be configurde ion vscode too it seems (dupliacet, again another method ???)

#

and not sure where to ask 🙂

#

yes suree i'll start with python V3 (hope in the new job they have not keep v2 ...)

#

for command line only, i juste read a blog speaking about pip freeze > requirements.txt, and in comment many people says : don't do this !

#

i've seen some speakinf on pyenv, other python setup.py, other cookiecuutle, or pyscaffold ... and seems all those tools designed in the same goal

#

additional note : i have a gitlab server, and will add a runner for add CI to my projects. seems the better is to have CI runs in docker instances, and then will need the requirements.txt (and dev-requirements.txt)

#

and for IDE, can you confirm that vscode is a good choice ? i first try pycharm, but too complicated at start , vscode is really more user friendly for now

#

(python3-virtualenv and python3-pip added on my system via apt)

alpine blaze Sep 27, 2019, 12:52 PM

#

some of these tools are higher level than others, and build on top of some of the other ones

#

i would advise to start by understanding (at least on a basic level) what python setup.py does, as it's the most fundamental one in python packaging

robust marsh Sep 27, 2019, 12:53 PM

#

seems taht pip is abovce setup.py, or using it at least (i was reading on this 🙂 )

alpine blaze Sep 27, 2019, 12:54 PM

#

yeah, i do have a gitlab as well, i've yet to setup ci again, (did so at previous company), it's really cool

#

pip is mostly search + download + call setup.py yes

robust marsh Sep 27, 2019, 12:55 PM

#

a whole SUPER stack to learn !

#

gitlab-ci, python, docker, ansible !

alpine blaze Sep 27, 2019, 12:56 PM

#

yeah, i would advise to add things one at a time though, as maintaining them will take you time, and if you added a lot at once, it might quickly get overwhelming

robust marsh Sep 27, 2019, 12:56 PM

#

at least, but really many things to understand (as i don't want to try blind "like this and i'll see"

alpine blaze Sep 27, 2019, 12:56 PM

#

CI is nice to have, but takes a lot of time to get working at first

robust marsh Sep 27, 2019, 12:57 PM

sadly very common

robust marsh Sep 27, 2019, 1:02 PM

and often working behind proxy/firewall too

#

and generally take the "latest current" version is not good, because if you try 2 weeks later, maybe another code

#

i prefer DL, test, and if ok i reproduce

#

and if newer version .. need to restart all

#

but at least, same version everywhere

#

(the same principle than using requirements.txt :)) )

alpine blaze Sep 27, 2019, 1:04 PM

yeah, but then once you have pinned versions in CI, you can update the version in a PR, see if things still work, and then merge

@tame spindle i'm pretty sure kivy is better to create beautiful GUI than electron, but it's different, it depends a lot on how familiar you are with web technologies (for electron) and opengl (for kivy).

bold gorge Sep 30, 2019, 9:35 PM

I haven't seen much of the documentation, but it's a bit confusing as to what i should subclass and what to use directly in .kv files

alpine blaze Sep 30, 2019, 9:36 PM

#

well, the doc might be useful to understand concepts, the we tried to present most aspects of the framework in the programming guide, and the API doc is very useful too (though you can also just have the code and look into it, which is what i prefer when i wonder how something works)

bold gorge Sep 30, 2019, 9:38 PM

#

Yeah the API doc is a big time saver ^^

#

i was all ready to code the syntax highlighting myself and there's this neat CodeInput that already does that

alpine blaze Sep 30, 2019, 9:39 PM

#

🙂

#

What's the objective of your editor btw? Are you doing it by curiosity, or do you plan features that you think are missing in other editors?

#

Code highlight is sometime broken because of line cuts if i remember well.

#

strings going over multiple lines for example

bold gorge Sep 30, 2019, 9:42 PM

#

It's just a small project for myself. I thought it was a neat idea being able to develop a simple application with so many capabilities. Hopefully by the time I'm satisfied with it, it will have a lot of features 🙂

alpine blaze Sep 30, 2019, 9:42 PM

Yeah it does that, and I also had this weird bug where a line goes invisible unless you change any character

But very happy with the lib overall

#

Also if anybody is brave enough to work with this smol editor it's open source aswell ^^

alpine blaze Oct 1, 2019, 9:36 PM

you mean using one library with the api of another? why not use the other? or why not learn the api of the first one instead? if these things have a different api and capabilities, there are certainly reasons for it

#

@thorny spruce I need to make it so there can be multiple windows at a time

thorny spruce Oct 5, 2019, 2:45 PM

#

Then you should use a tkinter.Toplevel window. You should only ever have one tk.Tk window

digital rose Oct 5, 2019, 2:45 PM

#

What does that do?

thorny spruce Oct 5, 2019, 2:45 PM

#

It's a widget that's another window

digital rose Oct 5, 2019, 2:46 PM

#

So I just make it root = tk.toplevel?

thorny spruce Oct 5, 2019, 2:47 PM

#

tk.Tk is your root window (your first one), any other windows you want should be a tk.Toplevel window

#

For example

import tkinter as tk

root = tk.Tk()
tk.Label(root, text='This is my root window').pack()

for i in range(3):
    win = tk.Toplevel(root)
    tk.Label(win, text=f'This is window #{i}').pack()

root.mainloop()

atomic wing Oct 5, 2019, 9:43 PM

rocky dragon Oct 5, 2019, 9:43 PM

you need to call .text or .data on those items to retrieve their values as found here https://doc.qt.io/qt-5/qlistwidgetitem.html

atomic wing Oct 5, 2019, 9:44 PM

#

ahh lemme try

rocky dragon Oct 5, 2019, 9:44 PM

#

qt stores almost everything in items so you can do more things with them

atomic wing Oct 5, 2019, 9:46 PM

#

I am still confused

#

Where do i use .data?

#

If I am not mistaken, .data takes in int value

rocky dragon Oct 5, 2019, 9:52 PM

#

you call it on each of the items. The role refers to which value you want to get, as it can store multiple (for display, and an internal for example) There are python docs here but I find them more confusing to navigate through https://doc.qt.io/qtforpython/PySide2/QtWidgets/QListWidgetItem.html

#

I believe what you want will be at role 0, or you can use the text method

I am using Kivy and trying to create a program that compares 2 lists. I managed to create it in a fairly reusable way based on this example. https://stackoverflow.com/questions/53834602/kivy-selectable-recycleview-inside-screen-manager
I am using two lists on my design, but I want the buttons on each of the lists to do different things (if you click on the one on the left to do something, if you click on the one on the right something else).


        BoxLayout:
            orientation: "horizontal"
            ListButtonBox:
                button_text: "Send to right"
            ListButtonBox:

sudden coral Oct 12, 2019, 10:25 PM

you'd need a widget that takes text input

and another widget that can display text

#

and maybe a button the user presses to signify they are done entering input

#

QLineEdit and QTextEdit can take text input

#

QLabel can display text output

#

You should refer to the documentation on these widgets to learn how to retrieve or set the text for them

#

And I said before, you'd use signals and slots so you can know when the button has been pressed and you can do whatever operation you want

@weary sun From a cursory reading, it looks like you are not using sizers. You really should. They automatically size the element based on available space and you can give it a behaviour to grow or not etc.

hollow mist Oct 13, 2019, 6:31 PM

#

QT and tkinter are not suitable

#

But you can easily use pygame to make a gui

#

a gui, in the end, is just images that serve as buttons and react on events like mouse over or clicks

#

or use pyglet

#

all you need is a renderer and input events to build a gui

#

https://www.pygame.org/wiki/gui

#

Tbh, i've spent two days migrating to pyglet and I am yet to feel any benefit.

#

I am sure I can create a basic UI but it seems like it can get quite complex, quite fast. And my skills are pretty mediocre.

hollow mist Oct 13, 2019, 6:34 PM

#

you are right there, but read the link

#

there are some readily available gui toolkits available

#

or stick with pyglet and use glooey

slender burrow Oct 13, 2019, 6:36 PM

#

I've read that page a few times and there's only Thorpy still active.

#

And i've heard a lot of criticism for it.

#

Though I can give it a go if nothing else jumps out!

hollow mist Oct 13, 2019, 6:36 PM

#

Okay, let's take it from this side: What kind of interface do you need?

#

Lists and complicated stuff? Or just buttons and health bars?

slender burrow Oct 13, 2019, 6:37 PM

#

The former. Aspirational would be Pillars of Eternity, but more realisticalll something along the lines of Tome4

hollow mist Oct 13, 2019, 6:38 PM

#

quite an undertaking you got there

hollow mist Oct 13, 2019, 6:39 PM

#

that looks really nice

slender burrow Oct 13, 2019, 6:39 PM

#

I've spent a year building the architecture so whilst I lack skills I don't lack dedication.

#

Totally agree! That's the bar I am aiming for.

does CeGUI have pythonic bindings?

CEGUIPython

#

try this out

#

CeGUI has been around for ages

#

#

Crap, the py bindings are a bit outdated as well

slender burrow Oct 13, 2019, 6:42 PM

"This page was last modified on 3 March 2011" 😦

#

I love their logo, though!

hollow mist Oct 13, 2019, 6:43 PM

#

CEGui is made for C++

#

Python is not their focus

#

and if a maintainer quits, not much you can do

slender burrow Oct 13, 2019, 6:45 PM

#

Agreed.

#

Maybe its a roll my own situation then!

hollow mist Oct 13, 2019, 6:47 PM

#

All you can do is search around and try things out

#

make sure to check your source into git and branch

slender burrow Oct 13, 2019, 6:48 PM

#

That's what I've been doing tbh, buddy. This was pretty much my last ditch effort to find a hidden gem. 😛

#

Thanks for your help, mate.

alpine blaze Oct 14, 2019, 11:03 PM

#

why not kivy?

#

oh my, that's a few days old, i guess i've not been around 😆

final flicker Oct 15, 2019, 6:37 PM

#

why does kivy force you to import things like this:
from kivy.uix.widget import Widget
instead of calling
import kivy class MyWindow(kivy.uix.widget.Widget)

digital rose Oct 15, 2019, 8:50 PM

#

@final flicker well it's because Label widget class is located in a separate module named label (label.py)
The directory is kivy/uix/label

Or maybe I got you wrong?

alpine blaze Oct 16, 2019, 9:07 PM

#

does it force you?

#

hm, yeah, the sub packages are not imported automatically

#

automatically importing them even if you don't need would make app startup slower because of loading unneeded things.

Hi, I'm trying to execute something when the Mouse Right Click is well clicked

    def eventFilter(self, QObject, event):
        if event.type() == QEvent.MouseButtonPress:
            if event.button() == Qt.RightButton:
                print("Finally!")

Why is this not working?

final flicker Oct 17, 2019, 3:58 PM

#

@alpine blaze im working on my rendering engine and id love to be able to directly be able to interact with my Widget subclass

#

class MyApp(App):
    def __init__(self):
        super().__init__()

    def build(self):
        return MyWidget()

#

thats how im doing it right now

#

but id love to be able to just call MyWidget

#

this is the end goal:

class MyEngine(MyWidget):
    def __init__(...):
      super()...
    def on_touch_down(self, touch): # this is overwriting the on_touch_down function in MyWidget
       ...
    def on_update(self): # this is also overwriting a function that runs on a clock
       ...

#

if feel like doing this is kinda sketchy:

class MyApp(App):
    def __init__(self):
        super().__init__()
        self.window = MyWidget(my_on_keyboard, other_event_function, ...)
        self.root = self.window
        kivy.clock.Clock.schedule_interval(self.window._update_data, 1 / 60)```
and then having all the actual event functions call the passed in args.

alpine blaze Oct 17, 2019, 5:05 PM

#

app.root always refers to the root widget of the app

#

so maybe you don't need all that contraption 😛

Hi, i was wondering if anyone could help with with Tkinter. I have spin boxes, and wanted to know if their was a way to check if they changed, so i can have some code run.

molten swan Oct 19, 2019, 8:55 AM

I would like to make a GUI skinning tool (windows application) for a game's UI. It needs to have drag and edit functionalities like you would see in a design app or a user friendly 2d game engine (see image).
I'm searching for a program, api or library which could help me achieve this.
I have no ideal how to call this kind of functionality so I can't search for it online.
As far as I know (please tell me if I'm wrong) it's possible in pyqt but very difficult because you'd have to make it from the ground up.
Thanks in advance for any suggestions, links of open source projects with this functionality or terms!

yup

final flicker Oct 19, 2019, 9:26 AM

nice

molten swan Oct 19, 2019, 9:27 AM

#

the basics of it's gui is a great example of what I'm trying to make.

proper glade Oct 19, 2019, 9:31 AM

#

a QGraphicsView would be a good choice for the canvas I think. It renders a QGraphicsScene, which manages a collection of renderable items such as widgets, shapes, pixmaps etc that can be placed at any position on the scene.

#

so you wouldnt have to reinvent any wheels as far as that's concerned

molten swan Oct 19, 2019, 9:33 AM

#

sounds good

#

is it only for displaying or would I be able to program user interaction in it?

proper glade Oct 19, 2019, 9:34 AM

#

you can intercept keyboard/mouse events and interact with the items on the scene however you want

molten swan Oct 19, 2019, 9:35 AM

#

sounds great!

#

I'll look into it

#

thx

proper glade Oct 19, 2019, 9:36 AM

#

check out this for how to implement drag n dropping https://doc.qt.io/qt-5/dnd.html

#

the examples are in c++ but should be fairly straightforward to translate to pyqt

#

and if you have any questions feel free to ask of course

#

another API you could use is Kivy, but im not as experienced with that so couldnt give you a worthwhile opinion on how well suited it is for this application. paging @alpine blaze

alpine blaze Oct 19, 2019, 9:43 AM

#

yeah, kivy seems appropriate to this, it's pretty much done to draw collections of arbitrary things, and to manage them by drag and drop.

#

you can check this very simple wysiwyg editor i hacked together sometime ago as an example https://gist.github.com/tshirtman/d1750e17c7cf268ff58536f3f7afbf2c

molten swan Oct 19, 2019, 9:51 AM

#

thanks! I'll try it with pyqt first because I already know it's basics, but it's a nice backup if I don't like the way it's done or get stuck in pyqt

alpine blaze Oct 19, 2019, 10:06 AM

#

ok, good luck either way 🙂

molten swan Oct 19, 2019, 3:11 PM

#

@proper glade I'm a bit stuck. I need QGraphicsObjects for my QGraphicsScene because of their signals but QGraphicsScene only takes QGraphicsRectItems. I also can't instantiate any QGraphicsObjects because they are abstract. I could be wrong about what I just said but this is what I understood from it

#

I'm just testing things right now but in the actual project I will need to make my own classes and somehow add them to the QGraphicsScene

proper glade Oct 19, 2019, 3:13 PM

#

https://doc.qt.io/qt-5/qgraphicsscene.html#addItem

#

you can use addItem to add any QGraphicsItem to a scene

#

(and therefore QGraphicsObject since it inherits from QGraphicsItem)

molten swan Oct 19, 2019, 3:16 PM

#

ahh

proper glade Oct 19, 2019, 3:18 PM

#

i believe to instantiate a QGraphicsObject you can easily make your own concrete subtype, or inherit from one of the currently available graphics item types and also add your own signals to it

molten swan Oct 19, 2019, 3:19 PM

#

could I also inherit from QGraphicsItem itself?

#

I'm trying but getting some errors

class ShortNote(QGraphicsItem):
    def __init__(self):
        super(QGraphicsItem, self).__init__()
    
    def dropEvent(event):
        print(event)

proper glade Oct 19, 2019, 3:21 PM

#

so either:

class LineItemWithSignals(qt.QGraphicsLineItem, qt.QObject):
    some_signal = pyqtSignal()

or something like ```python
class LineItemWithSignals(qt.QGraphicsLineItem):
class Signals(qt.QObject):
some_signal = pyqtSignal()

def __init__(*args, **kwargs):
    super().__init__(*args, **kwargs)
    
    self.signals = type(self).Signals()

#

yeah and you can inherit from QGraphicsObject to make it concrete

#

sorry, excuse the qt. prefix that's a force of habit

#

what errors are you getting?

molten swan Oct 19, 2019, 3:24 PM

#

one for super but that was fixed with *args, **kwargs

Hi, i am using tkinter and have my gui code in interface(). I have spinboxes which call ReadData() when they change. I need to get the values of the spinboxes in this function. I tried making them global and using .get but i am just getting this <bound method Spinbox.get of <tkinter.Spinbox object .!spinbox>>.

#

Anyone know anything else i can try?

karmic shoal Oct 20, 2019, 3:43 AM

#

do you have parenthesis after get? you should be calling the function like so: get(), since just having get results in the function itself being assigned to the variable rather than the return value of that function

@proper glade My items somehow move the view in the scene or something when I drag them on startup. But after doing it for a while it stops

📎 hmmmm.gif

proper glade Oct 20, 2019, 1:16 PM

#

@molten swan https://stackoverflow.com/a/47342558/10444096 this looks like it might solve your problem

#

note that setSceneRect is being called on the scene itself, with the rect of the view passed as argument

#

though it feels a bit backwards to me, like something that should be a function of the view rather than the scene

#

https://doc.qt.io/qt-5/qgraphicsview.html#sceneRect-prop

#

there we go, qgraphicsview has its own setSceneRect

@proper glade I'm sorry to bother you again. Just tell me if you are not interested in helping me every now and then throughout my project. That being said, I'm trying to make a list of all my custom GraphicsItem types which I could then drag into the GraphicsScene

📎 hmmmm.gif

proper glade Oct 20, 2019, 6:27 PM

#

it's all good

molten swan Oct 20, 2019, 6:27 PM

#

but QListWidgets only accept QListWidgetItems and they don't seem to to be able to hold classes as data

#

thanks a lot

#

I tried giving my GraphicsItem classes QListWidgetItems

#

but when I .setText() it gives errors

#

and without it won't display in the list (don't know if it's not added or just invisible because it has no name)

#

giving a normal QListWidgetItems text and adding it works fine

#

just to be clear, the goal is to instantiate a new class I dragged in and add it to the scene

proper glade Oct 20, 2019, 6:33 PM

#

it's been a while since ive worked with a situation like this but iirc there are a couple drag/drop events you gotta override and also probably call something on the view to enable drops in the first place. gimme a couple minutes to play around with it and ill get back to you. as for QListWidgetItems holding classes as data, you can create your own subtypes that can hold a reference to anything like any other python object.

something like this?

proper glade Oct 20, 2019, 6:40 PM

#

exactly

#

though self.customClass would just be object rather than object()

#

you want a reference to the class itself, rather than an instance of it

xD

proper glade Oct 20, 2019, 6:56 PM

#

and theres another file called qt.py which is just

from PyQt5.Qt import *
from PyQt5.Qt import Qt as constants

#

which i use in all my pyqt projects

#

anyway, the gist of it is that you gotta override a couple of drag*Event methods on the GraphicsView to accept the event

#

and also the thing with subclassing QListWidgetItem to store a reference to the class like before

scene.addWidget returns the item while scene.addItem does not

#

right, doesn't make much sense when you already have the item there to pass as argument 😛

#

scene.addWidget takes a widget and returns an item so it cuts out the work of converting the widget into a QGraphicsWidgetItem first

#

there's no such extra work to be done with addItem

molten swan Oct 20, 2019, 8:50 PM

ahh

was kind of confusing because while debugging everything seemed to work and didn't think of something like that

but makes sense

proper glade Oct 20, 2019, 8:52 PM

#

https://doc.qt.io/qt-5/qgraphicsscene.html#public-functions check out all the return types of the add* methods here

#

everything's gotta be in QGraphicsItem form first to be added to the scene so they gotta be converted first

#

the add* methods just make that more convenient for you

molten swan Oct 20, 2019, 8:56 PM

#

does that mean that the items inside the scene lose all their custom code?

proper glade Oct 20, 2019, 8:58 PM

#

i think custom widget behaviour is carried over

#

as for custom code for things like lines and polygons, i doubt it

#

theyre meant to be used more as values than anything else

#

if you have your own custom subtype of QGraphicsItem and define custom behaviour for it then thatll be carried over to

molten swan Oct 20, 2019, 8:59 PM

#

but mine are kept since they already inherit from QGraphicsItem right?

proper glade Oct 20, 2019, 8:59 PM

#

yes, youre adding those items directly to the scene

#

rather than converting some other object into a qgraphicsitem first

Any PyGTK Veterans here? I'm having some trouble with TextView resizing with large amounts (correction: no, 5 paragraphs is NOT large) of text. It's fine reizing larger, but resizing smaller is excruciatingly slow UI wise.

Agreed. It’s on a relatively fast machine using the proprietary Nvidia driver, but I had the same problem in a vm on a Mac host at work too.
I don’t see the grid getting incredibly huge, so I might continue down the tkinter path if I can get good inline spell checking working.

@alpine blaze can i somehow tell a kivy texture to clear itself? or do i just have to set it to 0 ever time?

alpine blaze Oct 21, 2019, 4:11 PM

#

i don't think we have a specific api for that, setting it to 0 should be fine

final flicker Oct 21, 2019, 4:11 PM

#

ok thx

#

i dont really get this:

When using a bytes representation of the data, for every change you have to regenerate the bytes instance, from perhaps a list, which is very inefficient. When using a buffer object, you can simply edit parts of the original data. Similarly, unless starting with a bytes object, converting to bytes requires a full copy, however, when using a buffer instance, no memory is copied, except to upload it to the GPU.```

#

from: https://kivy.org/doc/stable/api-kivy.graphics.texture.html

#

right now i have a 3d array (size[0], size[1], 3) and i just flatten it to blit it:
self.texture.blit_buffer(data.flatten(), colorfmt='rgb', bufferfmt='ubyte')

alpine blaze Oct 21, 2019, 4:44 PM

#

flatten certainly produce a copy that slow down things, and the explanation is that if you use a buffer object, it can update it in place, instead of creating a modified copy

I don't know if you can see it but it stutters and teleports the item

make sure you call super().mouseReleaseEvent(event) when overriding

#

and also event.ignore() just to make sure it's not consumed

#

oh hmm, not sure about ignore() actually

#

but anyway my best guess would be that you need to call the super method to let all the normal mouse processing stuff happen

molten swan Oct 23, 2019, 12:46 PM

it worked

it was the super

@elder valve according to the docs the 3rd and 4th args to addWidget in QGridLayout are span length not coords
https://doc.qt.io/qt-5/qgridlayout.html#addWidget-2

#

additionally you might need to do something with the alignments

#

@molten swan no worries

#

@elder valve also, i think the spacedoutness is just a byproduct of how QLineEdit is rendered

#

it's always meant to be a single line, so youll get the empty space around it

which is better for ui? tkinter or QT ?

proper glade Oct 23, 2019, 9:44 PM

#

tkinter is to qt what a tricycle is to a spaceship

#

but in seriousness, it depends on what kind of ui you're making

#

you can use both to great effect

#

but qt is a lot more advanced and performant

rocky dragon Oct 23, 2019, 9:54 PM

#

the disadvantage is that you need to get familiar with the framework and it's larger

#

but if those don't matter to you, it can be a lot better

ok thanks guys

If using tkinter. How do I connect items in a nav menu to change to a different window

autumn badge Oct 24, 2019, 2:39 AM

#

So people, what is your fav UI framework? Any opinions between PyQt and PySide2?

sudden coral Oct 24, 2019, 3:28 AM

#

PySide2 has substantially better docs it seems and is supported (more?) directly by Qt. But the docs don't matter too much since both libraries are pretty faithful to the original Qt library and thus not only do PySide2 docs generally apply to PyQt5, so do the C++ docs. PySide2 also uses a less-strict license compare to PyQt5.

#

However, PyQT5 does have support for some additional things from Qt that PySide2 currently does not https://wiki.qt.io/Qt_for_Python_Missing_Bindings.

#

I use PySide2 but at the end of the day there hasn't been a huge difference for me.

terse delta Oct 24, 2019, 3:36 AM

#

I use Wx with WxFormBuilder. Never needed anything better. Works great for what I do.

autumn badge Oct 24, 2019, 3:59 AM

#

Thanks both of you.
I was using PyQt for a while but wanted to use a UI framework that would allow me to create software that was closed source if i ever got the opportunity to sell some of my apps. Even if I were to sell apps, I know I could never ROI the license cost.
I tried some other UIs like Remi, Kivy, tkinter (again) as well as some of the other tkinter like bindings like PySimpleGUI and others. Some of those bindings are very easy to use and allow you to reduce the amount of code you have to write, but I have been finding the limits of those pretty quickly with a simple app.

I liked PyQt. I might have to give PySide2 a shot. Looking through the list of missing bindings in PySide2, I am not too worried. The apps I have planned currently would not need those

sudden coral Oct 24, 2019, 4:18 AM

#

I believe LGPL would let you make it closed source

#

which is what PySide2 has

autumn badge Oct 24, 2019, 4:18 AM

#

one thing i do not like is that VSCode tends to not like PySide2. Keeps saying that it cannot find the widgets, but the app still runs. I am still trying to whitelist QT5 in VSCode

sudden coral Oct 24, 2019, 4:18 AM

#

But don't take my word for it

autumn badge Oct 24, 2019, 4:19 AM

#

yea. those licenses confuse me

#

I dont "plan" on writing closed source, but i really want to keep that option open to me

sudden coral Oct 24, 2019, 4:19 AM

#

I think the other really mature one would be PyGTK, at least that is my assumption since it's based on GTK, which is mature

autumn badge Oct 24, 2019, 4:19 AM

#

yea

sudden coral Oct 24, 2019, 4:19 AM

I thought kivy was also pretty up there

autumn badge Oct 24, 2019, 4:22 AM

but it is not mature enough yet

sudden coral Oct 24, 2019, 4:22 AM

#

I wouldn't know I've not used it

autumn badge Oct 24, 2019, 4:23 AM

#

an app i wrote in PyQt, i rewrote in kivy

#

the UI looked a LOT better. More like a phone app than a desktop app. But, at the time, the functionality wasn't all there. I don't know about it now. I have not been following it

#

hmmmm. I will have to look into PyGTK a bit more. It seems about the same in the coding sense and there is even a builder (Glade) that I could use for some simple apps most likely

#

thanks again. you gave me a lot to think about

#

bed time for me

shoot. PyGTK is out. The target I am writing apps for are windows users. Dang it, that looked good too

alpine blaze Oct 24, 2019, 5:28 PM

i mean, there are always things we can improve, but you can still do a lot of apps

#

i've done a lot of them, at least, and i'm far from alone

elder valve Oct 24, 2019, 5:45 PM

#

@alpine blaze i believe a lot of people (including myself) just dont like the structure of Kivy.

alpine blaze Oct 24, 2019, 5:46 PM

#

😦

elder valve Oct 24, 2019, 5:46 PM

#

The default look of kivy, however is something i like a hell of a lot

#

I just prefer to force PyQt5 to look pretty cause i like having access to the entirity of Qt5

alpine blaze Oct 24, 2019, 5:48 PM

#

weird, i though our default look was actually quite a disadvantage, people tend to judge that and think all apps will look like that, and that it's ugly

#

i guess the truth of the second assertion is debatable, but the first one is essentially wrong, as you can change everything and draw anything

#

but do you don't like in the structure? how widgets are built? the package tree? the dispatch system? the graphical instructions?

elder valve Oct 24, 2019, 6:29 PM

#

The package tree mostly, though i did find a nice little solution to that

alpine blaze Oct 24, 2019, 7:06 PM

#

Interesting, how would you see it instead?

reef hound Oct 25, 2019, 6:51 AM

I am using PySimpleGUI, I want to use a similar function like FileBrowse(), but for the menu option.

[ 'Help', ['About::about_key'] ]
]

How do I have the same functionality for an import that brings up file explorer so I can import a file with N file type?

#

I have question about Pyqt5. How can I set number as a label <

#

*?

elder valve Oct 25, 2019, 8:26 PM

#

@alpine blaze would be good to have a gui package, where i can import all of the gui elements like is possible with PyQt5.

#

@versed trout what do you mean Sasi? Like the label 341?? If so just do label = QLabel(text="341")

#

I think you actually helped me with the programatic import in the kivy server tshirtman, it was something along the lines of this ```python
imports = {
'uix' : ['Label', 'Button'],
}

for k, v in imports.items():
for I in v:
i = I.lower()
globals().update({I:getattr(import_module(f'kivy.{k}.{i}'), I)})

#

I did refine it later on i think, but i dont have that snippet handy right now

alpine blaze Oct 25, 2019, 8:32 PM

#

hm, so like uix, but with all widgets from the submodules directly imported into it?

elder valve Oct 25, 2019, 8:32 PM

#

Yeah, basically.

versed trout Oct 25, 2019, 8:32 PM

@elder valve I figured it out the problem was I was calling the error so it did not worked

#

elder valve Oct 25, 2019, 8:33 PM

#

@versed trout okay, that doesnt sound like a thing that is possible but I'll take your word for it... feel free to explain yourself though

alpine blaze Oct 25, 2019, 8:35 PM

#

@elder valve i think we would need a way to do that that wouldn't impact the performances, because i think right now it would slow down app startup and certainly increase memory consumption overall

elder valve Oct 25, 2019, 8:35 PM

#

Yeah, the way that it's done is understandable, its just not fun to work with 😂 😂

alpine blaze Oct 25, 2019, 8:36 PM

#

there is an easy alternative though

#

from kivy.factory import Factory as F

F.Button()
F.Label()
… etc

elder valve Oct 25, 2019, 8:38 PM

#

That is something i had no idea existed. Wow, ive legitimately never seen that

#

what would one even search to find that given they don't know of its existence

alpine blaze Oct 25, 2019, 8:38 PM

#

(it works because all widgets in uix are registered in the factory in factory_registers.py, and you can have your own such module in your app to allow the same access to your widget without needing to preload them)

elder valve Oct 25, 2019, 8:39 PM

#

Thats p cool though, thanks!

alpine blaze Oct 25, 2019, 8:39 PM

#

Factory is used by kvlang to find the classes to use when you instanciate widgets in the string

elder valve Oct 25, 2019, 8:39 PM

#

Ah, that makes sense

alpine blaze Oct 25, 2019, 8:40 PM

#

yeah, it's the kind of things you kind of stumble upon :/

#

i should probably use it more in my examples to make people more aware of it

elder valve Oct 25, 2019, 8:40 PM

#

Yeah, lmao.

#

It would be good

#

Im probably going to use kivy more now that i know that.

alpine blaze Oct 25, 2019, 8:41 PM

#

but then i would need to explain why that works for kivy widgets, and not automatically for the widget classes defined by users, unless they have been imported before, or they use a similar factory_registers thing

#

hm, i'll try though 🙂

elder valve Oct 25, 2019, 8:42 PM

#

Perhaps Factory could be renamed to builtins? Idk how many files you'd have to refactor, but it would make it a lot more self explanatory @alpine blaze

#

I also don't know whether that would mask its other functions, but one would assume if someone knows the other uses of Factory, a name change wouldn't confuse them too much. I doubt many people will use it at the moment. Of course you could just make a package whose sole purpose is an alias for Factory, and leave Factory in tact

alpine blaze Oct 25, 2019, 8:45 PM

#

i do think Factory is a proper name, and builtins would be a misrepresentation, i guess the solution is just more/better documentation

elder valve Oct 25, 2019, 8:46 PM

#

Yeah, unfortunate solution, but a solution nonetheless

@molten swan did you figure out your double clicking issue

molten swan Oct 26, 2019, 8:05 AM

#

Not yet. I put it to the side and did some things I do know how to do

#

But the internet says I only need to give the items an 'editable' flag (doesn't work tho)

#

Also, I gave my QGraphicsItems a dragenter, dragmove and drop event and setAcceptDrops(True) but they don't recieve it when they're in the scene

#

could it be that either the view or the scene receives it instead?

Hello is there any way in PyQt5 to make the same window with different functions automaticly and don't copy paste the same code of the window all the time ? If yes then how can I ?

rocky dragon Oct 26, 2019, 1:01 PM

#

create a base class?

proper glade Oct 26, 2019, 1:27 PM

#

@molten swan not sure regarding event processing order but should be trivial to figure out with some debug output. in case either the scene or the view is consuming the event, you can use their itemAt methods to find whatever widget is under the mouse. additionally dont forget to event.accept() for the drag events.

#

as for making list widget items editable:

        self.setFlags(
            self.flags() | qt.constants.ItemIsEditable,
        )

on the item seems to be enough to make it editable

#

after i do this i can double click and edit the text inside with no extra effort

tribal path Oct 28, 2019, 7:29 PM

!or-gotcha

proven basinBOT Oct 28, 2019, 7:29 PM

#

When checking if something is equal to one thing or another, you might think that this is possible:

if favorite_fruit == 'grapefruit' or 'lemon':
    print("That's a weird favorite fruit to have.")

After all, that's how you would normally phrase it in plain English. In Python, however, you have to have complete instructions on both sides of the logical operator.

So, if you want to check if something is equal to one thing or another, there are two common ways:

# Like this...
if favorite_fruit == 'grapefruit' or favorite_fruit == 'lemon':
    print("That's a weird favorite fruit to have.")

# ...or like this.
if favorite_fruit in ('grapefruit', 'lemon'):
    print("That's a weird favorite fruit to have.")

tribal path Oct 28, 2019, 7:30 PM

I think applies, and not sure you can just in a file object

#

Well I've changed but still it is not showing the password username or email in the file

tribal path Oct 28, 2019, 7:44 PM

#

still using f? reopening a file before closing it could be an issue there too

open stump Oct 28, 2019, 7:46 PM

#

I belive you should do not in f.readlines() instead of not in f

versed trout Oct 28, 2019, 7:49 PM

#

if username1 and pass1 and email1 != username1 and pass1 and email1 in f:

open stump Oct 28, 2019, 7:50 PM

#

in f.readlines()

#

like so you gonna get a list of all rows in your file

email1 can't be in the file if the file is empty

#

as you said before you want to check if there is password or username and email in file and if they arent you want to write the email in the file ?

Yes this is what the function needs to do

Well I think I will rewrite the code

Now I've rewrited that function and now it is writing memory id into the txt file so now it is working

Hi guys!

#

I'm having some problems with tkinter

#

I'm new

#

from tkinter import *
from tkinter import scrolledtext
from tkinter import messagebox
from tkinter.ttk import Progressbar
from tkinter import filedialog
from tkinter import Menu


window = Tk()
window.title("My first TK!")
window.geometry("500x500")

text = Label(window, text="Hello there!", font=("Nunito", 30))
text.pack()

window.mainloop()

#

Why is the text cut off?

I haven't work with tkinter. but I had a similar problem with some fonts in kivy and pygame. I did not find a simple solution since I had a little time, so I just used different fonts.

Can anyone point me in the right direction for making a desktop app with Flask? @here

alpine blaze Oct 29, 2019, 11:44 PM

#

@digital rose certainly, but which one certainly depends on what your priorities are, i'm personally a fan (and contributor) of kivy, but a lot of people advocate pyqt/pyside for desktop apps, both have pros and cons.

digital rose Oct 29, 2019, 11:45 PM

#

yeah i am mostly interested in desktop apps

alpine blaze Oct 29, 2019, 11:46 PM

#

@lofty elbow flask is a backend, you need a way to display things, usually to build desktop apps with a web framework, you use electron or some other web view and front end technologies, html/css/js with react or vue or whatever to help build a modern front end.

Hi I'm making a TUI application.
(new to python so keep it simple please)
Pretty simple just imagine the main part of the window being output, ie print()
As well as a small box right at the bottom where you can input text. I have looked into curses for this and I roughly know how to do it. An issue I ran into is with the text box you can only type, backspace and return. No left/right or whatever.

I'm open to and libraries anyone suggests. Just want to get this done

hollow mist Oct 30, 2019, 5:35 PM

#

@lofty elbow It is not impossible, but I wouldn't do it: https://www.techiediaries.com/flask-electron-tutorial/

#

Electron is what runs discord on desktop

#

@brisk thicket PyQT and your woes are gone. pyWxWidgets if you need commercial usage without paying

#

Kivy if you want more eye candy

brisk thicket Oct 30, 2019, 9:12 PM

#

thx

alpine blaze Oct 31, 2019, 12:08 PM

#

i though the question was TUI, not GUI

#

there are usually two kinds of TUI, the graphical-like ones, with boxes and things, like curses allows, and the more shell/terminal oriented ones, where you type commands with sometime very neat autocompletion and feedback.

brisk thicket Oct 31, 2019, 2:31 PM

#

Haven’t looked into the 2 thing suggested. Basically a curses wrapper would suit I think

#

Curses has very poor support for text input without a lot of work I don’t know how to do

Try out whiptail, I cant remember whether it was Unix only, but I should be able to give you some python bindings

Do we have drag buttons in tkinter?

#

I mean like the circles we drag for example in color chooser and then colors change

spare verge Oct 31, 2019, 8:10 PM

#

I'm trying to use Kivy for the first time and just trying to get a scrollable list of buttons ```py
class MyApp(App):
def build(self):
layout = BoxLayout(orientation='vertical', size_hint_y=None)

    for i in range(50):
        layout.add_widget(Button(text=f'Button {i}', size_hint_y=0.1))

    root = ScrollView(size=(Window.width, Window.height))
    root.add_widget(layout)
    return root```

This is what I have right now but it's very broken and I don't know what direction I should go

#

oh hmm, if I do layout.height = 12345 it kind kinda works

#

not what I want but closer to it

spare verge Nov 1, 2019, 7:02 AM

I see

digital rose Nov 1, 2019, 7:03 AM

I used to do this using kv and GridLayout, something like this

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.gridlayout import GridLayout
from kivy.uix.button import Button


KV = """
ScrollView:
    size: self.size

    MyGridLayout
        cols: 1
        size_hint_y: None
        row_default_height: '50sp'
        height: self.minimum_height
"""

class MyGridLayout(GridLayout):
    def __init__(self, **kw):
        super().__init__(**kw)

        for i in range(50):
            self.add_widget(Button(text= str(i)))

class MyApp(App):
    def build(self):
        return Builder.load_string(KV)

MyApp().run()

#

also RecycleView is good if I have many items
https://kivy.org/doc/stable/api-kivy.uix.recycleview.html

#

Yea, it's not quite intuitive and a little cumbersome, but I suppose it's necessary to keep ScrollView "universal"

btw I think it’s easy (at least definitely possible) to implement a widget that behaves like a simple BoxLayout but has ScrollView behavior

Will check out Spinner, thanks

#

So the dropdown is meant to be an all-time-active widget?

alpine blaze Nov 3, 2019, 9:15 PM

#

it's meant to be dynamically added/removed from the widget tree, using its methods

#

this is what Spinner does

#

i know it's a bit confusing, but DropDown is a low level widget in kivy, kind of an implementation detail of Spinner, which is what people usually want

@stoic lynx i use and love kivy (and i'm/have been quite involved in the dev) it's easy to get started with and has a few nice things, like being a python first lib (not a wrapper of a C++ one) which makes it more natural to use in python, it's multiplatform (including android and ios), and it gives the same result on all of them, (though some people would prefer a native-like look on all plateform, i'm not one of them).

The simplest option for what you could do is use the "app" in the kv file as follows:

your main file (where your application runs from)

from kivy.app import App

    image_source = '1.jpg'


TestApp().run()

although it’s not always convenient

alpine blaze Nov 7, 2019, 10:28 PM

#

@green badger the other way is to give an id to your layout and to refer to that id in the python code, if the id is in the root rule, you should be able to use app.root.ids.the_id and use add_widget on it, to create a new image widget with the source inside, if it's not in the root rule, then you do need to get a reference to the widget for that rule, usually giving it an id in the rule that contains it, up until you are back at the root rule, so you can use app.root.ids.some_id.ids.some_other_id.ids.the_id or something like this.

rocky dragon Nov 7, 2019, 10:38 PM

a recent convo reminded me about a problem I wanted to get to a few months ago, can I tell Qt to only keep a single instance of a window or delete it after it's closed?
say I create it like this

    def end_route_pop(self):
        w = popups.RouteFinishedPop(self.main_window)
        w.show()
        w.close_signal.connect(self.main_window.disconnect_signals)
        w.new_route_signal.connect(self.new_route)

that runs fine but when the window is closed it stays in memory, while not much of a problem because tens of thousands of them would need to be opened to have a noticeable inpact, it's still I'd like to avoid

hallos, I'm looking for ideas for doing this better!
I'm just printing the status of some workers in a loop.
I'm interested in whether there's a better version of doing the screen update

⠼ 2
✓ 3
✓ 4
⠼ 5
⠼ 6
⠼ 7
✓ 8
✗ 9: Error: ...
⠼ 10

from blessings import Terminal
...
term = Terminal()
while True:
    ....

    for work, position in active_workers:
        with term.location(x=0), term.hidden_cursor():
            print(term.move_up * position, end="")
            print(f"{work.status} {work.name}", end="")

    ....
    sys.stdout.flush()
    sleep(...)

kind kraken Nov 8, 2019, 5:13 PM

#

you could use curses but that might be overkill

#

I'd probably clear the screen and include y=0 in term.location

#

instead of the move_up * position

#

that or get it all on one line (maybe skip printing the error information, i don't see how you're doing that) and just use '\r' instead of any library at all

#

oh, you can probably switch the term controls and the for loop

#

and just print them in order

#

hmm or something like py print('\n'*len(active_workers)+term.move_up*len(active_workers)) # clear space while True: with term.location(), term.hidden_cursor(): for work, position in active_workers: print(f"{work.status} {work.name}") # just print them on each line normally, the end of term.location() will move back to the top for the next time sleep...

#

@lyric cave

lyric cave Nov 8, 2019, 5:25 PM

#

Well, the organization of the information is preferential. The error information presented magically through str, I just elided that.
I mostly care about alternative versions of terminal positioning.

What would curses look like for updating a line at worker_position? And would it work on Windows too?

kind kraken Nov 8, 2019, 5:25 PM

#

i have no idea how or if blessings works on windows

lyric cave Nov 8, 2019, 5:25 PM

#

It do! :D

#

But, is curses maybe a better way to do this than blessings?

kind kraken Nov 8, 2019, 5:26 PM

#

like i said, curses might be overkill, it's a full screen management library rather than just moving the cursor

#

which lets you avoid garbage on the screen in edge cases like "what if an error message makes one of them take up more than one line"

#

just clearing the screen, and drawing the statuses from the top of the screen instead of near the bottom, might help with that too though

#

anyway
