77ffb593 38// wxWidgets uses the Microsoft convention that the origin is the UPPER left.
5fd2b2c6 39// Native OS/2 however in the GPI and PM define the origin as the LOWER left.
77ffb593 40// In order to map OS/2 GPI/PM y coordinates to wxWidgets coordinates we must
5fd2b2c6
DW		 41// perform the following transformation:
42//
43// Parent object height: POBJHEIGHT
44// Desried origin: WXORIGINY
45// Object to place's height: OBJHEIGHT
46//
77ffb593 47// To get the OS2 position from the wxWidgets one:
5fd2b2c6
DW		 48//
49// OS2Y = POBJHEIGHT - (WXORIGINY + OBJHEIGHT)
50//
51// For OS/2 wxDC's we will always determine m_vRclPaint as the size of the
52// OS/2 Presentation Space associated with the device context. y is the
77ffb593 53// desired application's y coordinate of the origin in wxWidgets space.
5fd2b2c6
DW		 54// objy is the height of the object we are going to draw.
