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