I would like to create a popup menu which appears
when the user pushes the LEFT mouse button. This
code ...
dev = qread(&val);
if ((dev == LEFTMOUSE) &&
(val == 1) {
item = dopup(menu);
}
... brings the menu up just fine, but the system
waits for the release of the right button. How
can I tell the system to watch the left button?
Thanks. Please send mail, I will summarize.

I spent a little time researching this, and didn't come up with any good solutions. The problem is that the pop-up menu is based on the 4Sight (NeWS) menu class LitePullRightMenu, which is based on LiteMenu, etc. This menu substrate has low-level code that uses the binding of MenuButton for menu selection. By default, MenuButton is the right mouse button (look in /usr/NeWS/lib/NeWS/init.ps). So, as far as I can tell, you can probably rebind MenuButton to be the left button by changing this. However, looks like you'd impact all menus. Despite my best attempts (and limited time), I can't figure out if there is a Lite method that can be overriden to solve this. -- dan haug Merit Technology, Inc. ==================================================================== Phonenet: (512)338-2450 Internet: execu!sequoia!meritaus!dan@cs.utexas.edu UUCP: {uunet, cs.utexas.edu!execu, texbell}!sequoia!meritaus!dan
