Al,
Thanks for your offer to look at my program! It's not at all sensitive,
it's just a "variation" on a portion of Judith's improvement of the IDE,
which allows the user to paste any Euphoria or Win32Lib routine directly
into the IDE Code Editor by just selecting it from a (categorized) list(s)
in two pairs of combo boxes (one pair for Euphoria categories & routines,
another pair for Win32Lib). I have that working, and then thought to make
"right click" on a routine's name in one of those combo box's list make a
jump to the html doc section describing that routine, & discovered that I
couldn't make right click *work* in the list of a combo box. It *does*
"work" in the *edit* portion of the combo box, though.
I've attached a short demo of the problem, it's just your original with a
few modifications. I tried it with Win32Lib .50, .53, and with .54 (with the
CB_ constants commented out for .54, 'cause they're in it).
In the demo, if you "open" (drop-down) the list by clicking on either the
edit box or the triangle, and then try to *right click* on an item in the
list, *nothing at all happens*. If you *left click* an item, the list
closes, and the item left-clicked on (which gets properly selected), is
placed into the "edit" box (really a static label in a simple combo), and
*this* is where right click *does* sort-of work: if you *right click* on
the "edit" box, ITEM NUMBER 1 gets put into the "edit" box (no matter what
had been selected by left click), & pulled out by your routine to be put
into a data label.
I didn't zip up everything you asked for because I think when you see how
the demo works, you really won't need anything else; if you still think you
need to see the whole thing after looking at the demo, let me know & I'll
put it all together for you.
