[Xpert]Hot corners

[Mike Schiraldi]

Some screensavers in the Win / Mac world let you set hot corners and cold
corners, which respectively immediately activate the screen saver and
inhibit it.

I'm working on a program that lets you do this with X11. It almost
works. The problem is that it only notices if the corner belongs to the root
window -- if another window is covering the root, my program doesn't get
notified of the PointerMotion event. 

Since it's so tiny, i've attached it. I was wondering if anyone could take a
quick look. I imagine it would be a simple fix; but i've never programmed in
X before, and i'm sort of figuring it out as i go along by ripping apart
other programs.

Thanks

[Xpert]Binding mouse buttons to keys?

[Mike Schiraldi]

I've got some extra buttons on my mouse, and if possible, i'd like to bind
one of them to the Alt key and another to Ctrl. For example, in my window
manager, i can currently use Alt-Mouse1 to drag a window around. I'd like to
be able to do this by holding Mouse6 and then pressing Mouse1.

Note that it's not good enough to just bind mouse presses to keypresses -- i
need to grab both the button down event and the button up event. 

Thanks
