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