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