77ffb593 39// wxWidgets uses the Microsoft convention that the origin is the UPPER left.
5fd2b2c6 40// Native OS/2 however in the GPI and PM define the origin as the LOWER left.
77ffb593 41// In order to map OS/2 GPI/PM y coordinates to wxWidgets coordinates we must
5fd2b2c6
DW		 42// perform the following transformation:
43//
44// Parent object height: POBJHEIGHT
45// Desried origin: WXORIGINY
46// Object to place's height: OBJHEIGHT
47//
77ffb593 48// To get the OS2 position from the wxWidgets one:
5fd2b2c6
DW		 49//
50// OS2Y = POBJHEIGHT - (WXORIGINY + OBJHEIGHT)
51//
52// For OS/2 wxDC's we will always determine m_vRclPaint as the size of the
53// OS/2 Presentation Space associated with the device context. y is the
77ffb593 54// desired application's y coordinate of the origin in wxWidgets space.
5fd2b2c6
