ClickableLabel | ClickableLabel - A github repo linked to the Medium post

I am beating my head against a wall trying to figure out how to resize and rearrange the camera app I am building on Raspberry Pi. I want to be able to resize the window by tapping on the video, from a full-screen app to a smaller version that will display in the corner of my touch screen.

I'm using OpenCV to run the camera itself. While the point of the app is to run 4 cameras and switch between them, that all happens in external hardware, so just think of it as displaying one USB webcam. I'm not completely set on using OpenCV for this, but it's worked so far.

I also seem to get segmentation faults on my RPi 4 when I try to adjust the size, minimize, or maximize the window. Not sure if that's related, but I've tried it using two brand new SD cards hoping to rule out a hardware problem.

What I've tried:

• Programatically rearranging the window. Won't display video and also gives me a segmentation fault.

• Subclassing MyWindowClass into BigWindowClass and SmallWindowClass, then sending the separate .ui files to their respective classes, then using the .show() and .hide() methods to determine which one I want displayed. This will show the video in the big window, but not the small one.

I left out a few of my functions for clarity's sake, but the full source code is in the github link above.

I need to ask you guys for advice, as I'm running out of ideas. I'm working onclickable label. I have already done some "clickable label" class and handled mouseover event - which changes the label border and returns to the normal state when the mouse leaves.

Now I want it to have a custom glow effect on the label, but I want it to return to normal state after, let's say 0.5 s from a click.

I want my label with an image to imitate button. time.sleep does not work nice, especially with spamming clicks it freezes application main thread.

Hope I am not reinventing the wheel but as far as I know that's the way to go.

Heres the sample code, any answer is appreciated.

My actual application is much more complicated than this, but the example below sums up the majority of my problem. I have multiple QLabels that I've subclassed to make them clickable. The labels display 16x16 images which requires a process of loading the images via Pillow, converting them to ImageQt objects, and then setting the pixmap of the label. In the example, I have 3 clickable QLabels that run the print_something function each time I click on them. My goal is to be able to hold the mouse down, and for each label I hover over, the function gets called. Any pointers would be great.

I want to have a QLabel in Qt which reacts to the mouse click event. I have found various similar solutions that don't seem to work in my current version 5.8.x

This seems to be the consensus on how to accomplish what I want: https://wiki.qt.io/Clickable_QLabel

If I take that, the program fails to compile with the error:

So I am making an GUI in Qt, my problem is that Qt seems to ignore border image of Qlabel. Here is my cards.qrc:

I am trying to make labels overlap each other in QVBoxLayout like this:

Lets assume we have grid layout like this:

Lets have ClickableLabel like this:
