Guys,
As part of QDT's drag and drop, I am trying to set the mode into xor
to allow me to temporarily put an outline onto a part of the window
and then restore it.
I am doing this with C68 (basically calls the machine code wrapper),
using the iow_sova call. When I set the mode to DM_OVER, it draws my
outline OK. However, when I set it to DM_XOR, it does draw
anything. I also found this to be true if I set it to DM_OR.
Is there a limitation with high color modes and drawing in OR or XOR
mode?
In SuperBasic it works fine in the original QL color mode.
Does anyone have an alternate suggestion to drawing a temporary
outline and then being able to restore it on different parts of the
screen?
Thanks for the help,
jim
