Re: [minos] mouse events

[Sergey Plis]

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.
