| Summary | 0038592: LCLQT5 doesn't call ThemeServices.OnThemeChange | ||||
| Description | LCLQT5 doesn't call ThemeServices.OnThemeChange when the style is changed via QApplication_setStyle or externally if you're using qt5ct and change the system style while it's running. TQtWidgetSet.EventFilter does have a case for QEventStyleChange that gets hit a bunch, but it never matches the "Sender = QCoreApplication_instance" check. It seems like OnThemeChange should also be called when the application palette changes (related issue, 0038589) | ||||
| Steps To Reproduce | The attached app has a listbox on the left that lists all of the styles available, and clicking on an item calls QApplication_setStyle. The SetPalette button just sets the application palette to random colors. The listbox below the button should add a message any time OnThemeChange or WMThemeChanged are encountered, but neither of them ever are. To test, run it and click on the various styles, or install qt5ct, use the "qt5ct-style" style, then run qt5ct while the test app is still open and change the active style or palette. Adding a WriteLn in TQtWidgetSet.EventFilter's QEventStyleChange, outside the if block, does get hit. | ||||
