P2: Important Description
I can no longer set the orientation property of QSplitter through QMetaObject using an enum value. This is easier to show than explain:
import sys from PySide6.QtCore import Qt from PySide6.QtWidgets import QApplication, QMainWindow, QSplitter app = QApplication(sys.argv) window = QMainWindow() splitter = QSplitter(window) print("Starting") def set_property(name, value): meta_obj = splitter.metaObject() i = meta_obj.indexOfProperty(name) was_success = meta_obj.property.write(splitter, value) print("Success:", was_success) set_property("orientation", Qt.Vertical) # Set enum value with property - FAILS set_property("orientation", 2) # Set numerical value with property - works splitter.setOrientation(Qt.Vertical) # Set directly - works set_property("toolTip", "foo") # Set other property - works
I tried in 6.2.4 and this fails (the return value from property.write() is false, and you can see that the write has failed if you display the component). In 6.2.3 it works (I also tried 6.2.2, 6.2.0 and 6.1.3) so this is a regression. I suspect it could be related to this entry in the changelog:
