77ffb593 40// wxWidgets uses the Microsoft convention that the origin is the UPPER left.
5fd2b2c6 41// Native OS/2 however in the GPI and PM define the origin as the LOWER left.
77ffb593 42// In order to map OS/2 GPI/PM y coordinates to wxWidgets coordinates we must
5fd2b2c6
DW		 43// perform the following transformation:
44//
45// Parent object height: POBJHEIGHT
46// Desried origin: WXORIGINY
47// Object to place's height: OBJHEIGHT
48//
77ffb593 49// To get the OS2 position from the wxWidgets one:
5fd2b2c6
DW		 50//
51// OS2Y = POBJHEIGHT - (WXORIGINY + OBJHEIGHT)
52//
53// For OS/2 wxDC's we will always determine m_vRclPaint as the size of the
54// OS/2 Presentation Space associated with the device context. y is the
77ffb593 55// desired application's y coordinate of the origin in wxWidgets space.
5fd2b2c6
DW		 56// objy is the height of the object we are going to draw.
57//
58#define OS2Y(y, objy) ((m_vRclPaint.yTop - m_vRclPaint.yBottom) - (y + objy))
