Re: [WIN]Win32Lib: v50 : trap click in SIMPLE combo?
Derek,
That's ok; besides, it was a *good* example, just not quite what I needed!
:)
But I think your last suggestion only works with v 54.5?? See, I'm trying
to get this to work with v50, 'cause it relates to my modification of
Judith's IDE & that's not yet built to run under 54.5. I'm beginning to
think that maybe I *can't* do this under v50 (& even if I could, by making
changes to v50, that wouldn't really help, 'cause I wouldn't want to have to
distribute the changed Win32Lib in order to get my mod to the IDE to work).
Wolfgang has sent me a list of Combo Box Notifications, not sure if they
will help, but I'll give them a look.
Maybe if I tell you exactly what I'm trying to do, that might help:
In my mod of Judith's IDE I have pairs of combo boxes, one above the other
in each pair; each of mine have a list of *categories* in the top box, and a
(variable) list of routines in the bottom of the pair; when a category is
selected from the top of a pair, it causes the bottom combo to become
populated with the appropriate list of routines for that category, opens the
bottom list, and either closes automatically or is closed by command (I
forget which); this much works, you can see it in the latest version at user
contributions at RDS.
What is supposed to happen next is that if the user clicks on the
*categories* list while the lower *routines* list is down, it is *supposed*
to close the lower list so it doesn't show "under" the other list if the
lower list is too long. This also does work.
The problem is that all of that works when the combo box is a *regular*
combo box, with an *editable* control at the top, and if that is
accidentally changed by a user, it crashes the IDE; so I thought to make it
*uneditable* to fix that "crash potential", but when I do that, I loose the
"close the bottom list when the top list opens" capability, because I was
using "onGotFocus" to let me know when the user had clicked on the top
combo, and when I use "SimpleCombo" it doesn't/can't get focus because it
has a static text item, which can't get focus.
If that's not clear in relation to my Mod, I'll try to send you a demo, but
I'm having trouble with my phone lines & can't be sure when I'll be able to
send/receive email.
Dan
