| 43 | // Native OS/2 however in the GPI and PM define the origin as the LOWER left. |
| 44 | // In order to map OS/2 GPI/PM y coordinates to wxWidgets coordinates we must |
| 45 | // perform the following transformation: |
| 46 | // |
| 47 | // Parent object height: POBJHEIGHT |
| 48 | // Desried origin: WXORIGINY |
| 49 | // Object to place's height: OBJHEIGHT |
| 50 | // |
| 51 | // To get the OS2 position from the wxWidgets one: |
| 52 | // |
| 53 | // OS2Y = POBJHEIGHT - (WXORIGINY + OBJHEIGHT) |
| 54 | // |
| 55 | // For OS/2 wxDC's we will always determine m_vRclPaint as the size of the |
| 56 | // OS/2 Presentation Space associated with the device context. y is the |
| 57 | // desired application's y coordinate of the origin in wxWidgets space. |
