Thank you!
Here is the problem I have. My code
\ here I have x y mouse positions which I got with the CODE: field of
glcanvas in theseus
DOPRESS
\ some variables initialization
0 framew ! 0 frameh !
\ record new mouse position since I use it to paint
2dup
yclicked ! xclicked !
\ throw away everything except the last x y coordinates
2swap 2drop 2swap 2drop
\ repaint glcanvas
gear-task @ IF make-gear-task THEN
When I click on the glcanvas the procedure starts (I look what's on
the stack before DOPRESS gets called) and does nothing. Even my mouse
is up already when I move it away from glcanvas to a button DOPRESS
starts working (again I see what's on the stack). Except the latest x
y coordinates are on the button, not where I raised the mouse on the
stack.
What I do wrong?
Thanks in advance.
