That's how I would have implemented in it fpGUI as well. The higher
level code uses x, y as normal. The drawing backend code does
conversions

If done right, the code doing coordinate conversion should be in library

A little bit late, as I have done most of the drawing conversion
already. But your post is still handy if I ever wanted to support OS/2
in fpGUI. A clever solution. I'll file your post for future reference

I suppose I can see the merits for using each of the co-ordinate sy

Hi,
I'm porting an OS/2 application to Linux & Windows. From what I can
see in the code, it looks like co-ordinates (0,0) is in the bottom
left corner of the screen. Whereas Windows and Linux, co-ordinates
(0,0) is in the Top Left of the screen.
Is my assumption correct? If so, DAMN! This is go
