// DoSetSizeIntr and DoMoveWindowIntr

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