| 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 |
