| 56 | // under Motif composite controls (such as wxCalendarCtrl or generic wxSpinCtrl |
| 57 | // did nott work and/or segfaulted because |
| 58 | // 1) wxWindow::Create calls SetSize, |
| 59 | // which results in a call to DoSetSize much earlier than in the other ports |
| 60 | // 2) if wxWindow::Create is called (wxControl::Create calls it) |
| 61 | // then DoSetSize is never called, causing layout problems in composite |
| 62 | // controls |
| 63 | // |
| 64 | // SOLUTION: |
| 65 | // 1) don't call SetSize, DoSetSize, DoMoveWindow, DoGetPosition, |
| 66 | // DoSetPosition directly or indirectly from wxWindow::Create |
| 67 | // 2) call DoMoveWindow from DoSetSize, allowing controls to override it |
