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
