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