Resulting in a name of "myMainWindowWidgetWindow" ? :) Yves: you're confusing QWindows and QWidgets. For historical reasons, QMainWindow is a widget, not a window. It's a very old class, dating back to the very early 1990s, when Qt didn't have a distinction between widgets and windows. Until 5.0, the a (top-level) window simply was any widget that had no parent widget. That's why some API in QtWidgets has "Window" in the name, such as QMainWindow and QApplication::activeWindow(). When Qt 5.0 split the widget content from QtGui into QtWidgets, it added QWindow, which is always a windowing system window, but carries no widget baggage. All QWidgets that have no parent (and some that do) are also associated with a QWindow. That's where the "Window" suffix gets added. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel DPG Cloud Engineering _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
