53// DoSetSizeIntr and CanvasSetSizeIntr
54// PROBLEM:
55// under Motif composite controls (such as wxCalendarCtrl or generic wxSpinCtrl
56// don't work and/or segfault because
57// 1) wxWindow::Create calls SetSize,
58// which results in a call to DoSetSize much earlier than in the other ports
59// 2) if wxWindow::Create is called (wxControl::Create calls it)
60// then DoSetSize is never called, causing layout problems in composite
61// controls
62//
63// SOLUTION:
64// 1) don't call SetSize, DoSetSize, DoMoveWindow, DoGetPosition,
65// DoSetPosition directly or indirectly from wxWindow::Create
66// 2) call DoMoveWindow from DoSetSize, allowing controls to override it,
67// but make wxWindow::DoMoveWindow a no-op if it is called from
68// an overridden DoMoveWindow (i.e. wxFoo::DoMoveWindow calls
69// wxWindow::DoMoveWindow; this is to preserve the behaviour
70// before this change
