strange behaviour in hight DPI resolution

Fakhreddine

Hello, I use PySide2 version 5.15.2.1
When I ran the app on hight dpi resolution the app open but I can't do anything. I have a strange cursor that not click.

PS : I have added lignes for scale :

if hasattr(QtCore.Qt, 'AA_EnableHighDpiScaling'):
QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling, True)

if hasattr(QtCore.Qt, 'AA_UseHighDpiPixmaps'):
QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_UseHighDpiPixmaps, True)

Thank you in advence !

Hi and welcome to devnet,

What kind of device is that ?
Which OS are you running ?

Fakhreddine

Hi @SGaist , Thank you :)

The os is windows (tested on10 and 11). and I tried on multiples devices with hight DPI (when scale is more than 125%).

For example a dell XPS 13" 3840x2160 (250% Scale).

Do you have the same issue with PySide6 ?

Fakhreddine

I didn't try with pyside6. The project is heavy this will teak time to port it.

SGaist

Before doing such a port, you could try with a dummy application that exhibits this behaviour.

Note that the port should mostly be straightforward. It was one of the goal of Qt 6: to be a "boring" upgrade.

Yes you are right @SGaist I will do. Thanks a lot !

Hello,

I found the problem. It's because I use qtwinextra to custumize the window control bar.

The problem is solved.

SGaist

Glad you found out !

What did you do to fix it ?

Fakhreddine

@SGaist Nothing sepacial, back to normal windows control bar.

Now I have to find away to control the bar color.
Any idea please ? I read that this can be done using win32api but I don't find yet how to implement this using python/pyside.

Thank you

SGaist

I haven't used it but maybe the pywin32 module might allow to do that.

@SGaist ok merci :)
