Is this also expected?
As a further isolation of this problem... I'm finding that adding a QGLWidget (not even customized) into my view hierarchy (QMainWindow -> QWidget/QVBoxLayout -> QStackedWidget -> QWidget/QVBoxLayout -> QGLWidget) makes bad things happen to layouts, displays and mouse handling. Anyone have success with QGLWidget in a complex hierarchy on Qt 5.0 / Mac OS 10.8.1? Any known issues? This issue looks similar, but I'm seeing it on the Mac: https://bugreports.qt-project.org/browse/QTBUG-26826 _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
