Hi all,
I have an application that can take over a minute drawing to the
display. I would like
to give the customer the ability to cancel drawing at any point by using
some control
character. I would would also like to interrupt a current paint if the
user clicks on a
button or control that would cause a later repaint.
Currently the paint code executes in the same thread as the GUI. The
user can move
the cursor around while painting. Mouse clicks, however, are not
processed until the
paint is complete. My question is how can I find out what mouse clicks
are pending
or control character are typed while painting (without adding too much
of a performance
penalty)?
