Sorry if this comes off as a noob question. But I know that the Qt framework exposes a (cross platform) API for stuff like windowing, graphics (GPU), networking, threads, audio and the filesystem. That seems pretty much the whole gamut of the stuff that an OS's API provides. Does the Qt framework's API cover all the capabilities of it's target OS APIs? submitted by /u/Critical-Reason712 [visit reddit] [comments ..read more

I'm using PyQt6 if that matters. I'm very new to Qt and quite new to programming itself. I have multiple QGraphicsSvgItems (country borders) I wish to use as clickable objects. I have successfully defined the mousePressEvent so that clicking on the svg works as intended. However, the clickable area for each svg item seems to be their bounding box instead of the area inside the country border path. This leads to the clickable areas overlapping causing issues. Is it possible to have the clickable area for the svg items be only inside the path making up the country border? This is the map svg fi ..read more

The issue is that I am kind of having troubles learning Qt, there are lots of tutorials on the net, sure, but the ones I find are either too theoretical talking about in depth Qt technical aspects or either too practical using the Qt creator, that I don't think really adapted to my already existing repo. The way I want to design things looks a bit weird to do using Qt designer and I can't find a good tuto ..read more

Creating a GUI with banner buttons at the top and a collapsible widget on the left side that is populated by the buttons in the banner and popped out over the central widget.

Hi! I am wondering if anyone could help me here. I have an application making use of QOpenGLWidget. When I run the app, i get such error inside docker container. failed to create drawable failed to create drawable If application is executed directly on my machine everything works correctly.

To reproduce the problem I figured out very simple python code: import sys from PyQt6.QtWidgets import QApplication, QLabel, QWidget from PyQt6.QtOpenGLWi ..read more
