I recently wrote an application for which I used WinTrackRect
which was a big help, but I found that I could not
get the tracking box to reflect through the origin. In my
application, the user could only move the tracking box along
the x-axis. I want the user to be able to push button 1 and
drag the box either right or left. I tried the _LEFT and _RIGHT
(I don't exactly remember the names of the constants) specifiers,
and both, and the behavior I was able to get was the box expanding
to the right, or to the left of the origin, but not being able
to cross the origin. I think this is because I specified a
minimum x-axis size of 1, but when I tried zero, the function
behaved oddly.
Has anyone else run across this problem? Does anyone have a
solution short of writing my own rubberbanding/mouse-tracking
routine?
Thanks,
Pete.
