51 | // DoSetSizeIntr and DoMoveWindowIntr | |
52 | // PROBLEM: | |
53 | // under Motif composite controls (such as wxCalendarCtrl or generic wxSpinCtrl | |
54 | // did nott work and/or segfaulted because | |
55 | // 1) wxWindow::Create calls SetSize, | |
56 | // which results in a call to DoSetSize much earlier than in the other ports | |
57 | // 2) if wxWindow::Create is called (wxControl::Create calls it) | |
58 | // then DoSetSize is never called, causing layout problems in composite | |
59 | // controls | |
60 | // | |
61 | // SOLUTION: | |
62 | // 1) don't call SetSize, DoSetSize, DoMoveWindow, DoGetPosition, | |
63 | // DoSetPosition directly or indirectly from wxWindow::Create | |
64 | // 2) call DoMoveWindow from DoSetSize, allowing controls to override it | |
