is there a zoom-independent setting for QAbstractGraphicsShapeItem as well?

QAbstractGraphicsShapeItem has a setPen method, so you can give it a cosmetic pen.

@JonB said in hello，I have a problem:

Well, because showing/maximizing after minimizing causes a showEvent().
Press Win + D for the first time and all windows will be minimized. Press Win + D again and all windows will be restored. However, when I use EventFilter and rewrite the show event, after I press Win + D for the first time, the widget is minimized, which is normal. However, I do not press the win + D key combination for the second time, but randomly click any other icon on the desktop, which will trigger the show event of the widget of this QT program. Note that even if I do not click the icon of this program, it will trigger

You can check out this code. This is a preliminary code of designing flying 2D wings,. Or we call it an Airfoil. You can give any range of camber and thick ness and their position the corresponding airfoil will be generated. The control points or anchors will be shown in red color.

Hey!
Thanks for your reply!
Yes, I downloaded the source code for Qt6.4.0 beta. Compiled it with support for "text to speech". In the new version there are more "engines" for "text to speech". And a few more features. But the speech did not get better. I suspect that the operating system's underlying capacity for speech synthesis does not work as well on Linux as on Windows.

It's just my speculations. But Qt version 5.15.5 (the latest version available as open source) gave better sound than version 5.15.2. A better and more natural pronunciation. I thought.

I need to learn more about how operating systems handle speech synthesis.

Infos updated!!
