The top level widget uses a QWindow in Qt 5. Because of the platform abstraction layer (QWindow and QPlatformWindow), the platform dependent widget attributes often doesn't have an effect in Qt 5.
I have had a couple of stabs on solving this, but it has led to a big fat nothing so far. However, your mail just show yet another example for the need for a "pattern" to solve this. The other day Laszlo got a patch integrated which adds a new module called QtPlatformHeaders which (as the name implies) should only contain headers and no library. So I desided to use the new module and have another stab at adding an api for setting platform specific properties in change: https://codereview.qt-project.org/#change,84484 Jørgen _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
