Mac OS X
active QStatusBar vetoes resize commands coming from accessibility
Steps to reproduce / test case
Its possible to use the Accessibility API to move windows around and to resize them. E.g. unix/X11 includes this feature as a way of moving windows around without having to use the 'official' method of dragging, e.g. find the title bar, click down and begin moving.
If the QStatusBar has its setSizeGripEnabled set to true - then accessibility events to resize the window are
ignored. Likely because QStatusBar is not passing them onwards or ignoring them?
I've included a demo program that was used for another bug report (QTBUG-4964) - but its also useful for this one. Play with the setSizeGripEnabled feature and use Zooom/2 to resize the window - you'll notice that as soon as you turn off the size grip, that Zooom/2 is able to resize the window.
