1. [Win32Lib] ComboBox drop-down doesn't move with window
Below is a demo of a problem I've encountered with combo-boxes:
if I make the list drop-down, & then move the window, the drop-down list
remains where it was instead of moving with the window, though it is still
functional. Both combos in the demo exhibit the problem, the first is
"auto" drop-downed, the second has the same problem if the user clicks on
the drop-down arrow & then moves the window.
Is this a bug? What's the best way to fix this?

I don't know if this helps at all, I just tried 4 or 5
other 'Windows' programs and everyone of them closed
the dropdown when I clicked to another part of the
window. I guess that way it could never be open
during a window move. btw one of my programs with
DropDownLists behaves like your demo. Chris

Bug?!?! No this is a feature 
Actually, what win32lib should be doing is when a combo loses focus, a
message should be sent to it to close-up the dropdown list. I'll add this
to the list of items to improve win32lib.

Feature indeed! :)
In the meantime, should I just use an "onLostFocus" event for the combo to
close the list?
Didn't you just come back from vacation?

5. Re: [Win32Lib] ComboBox drop-down doesn't move with window
Ok, "onLostFocus" doesn't work as a trap when moving a window, but onPaint
the window, with CB_SHOWDROPDOWN, False,0, will close the drop-down;
however, what if I have more than one combo, & would like them to just
remain as they happen to be, up if up, down if down, when moving the window?
In other words, how can I find out whether a combo has its list dropped down
or not?

7. Re: [Win32Lib] ComboBox drop-down doesn't move with window
But now I see another problem:
if a drop-down list has been scrolled downward, & the window it's in is
moved, it would be nice to have the list be shown after the move just as it
was before; so I tried to use "CB_GETTOPINDEX", which is supposed to get the
index of the topmost *showing* item on the list. But when I do so, I always
get a return of "0", instead of the zero based index of the topmost showing
item. Anyone have any idea what I'm doing wrong?
Dan Moyer
Here's the code I used in the onPaint event trap:
result = sendMessage ( Combo2, CB_GETDROPPEDSTATE , 0, 0 )
if result = 1 then
result= sendMessage ( Combo2, CB_GETTOPINDEX , 0, 0 )
puts(1, sprint(result))
if result > 0 then
dummy = sendMessage(Combo2, CB_SETTOPINDEX, result,0)
end if
dummy = sendMessage(Combo2, CB_SHOWDROPDOWN, False,0)
dummy = sendMessage(Combo2, CB_SHOWDROPDOWN, True,0)
end if

Dan, I am glad I was able to help you work through this!
I will continue to assist with the Top Index issue in the same zealous

Hi Dan,
See if this does what you want. I also changed w32HPaint to w32HEvent so the
colapse and reshow of the combos would not happen when resizing the main
window.

11. Re: [Win32Lib] ComboBox drop-down doesn't move with window
Judith,
Well, not exactly: your clever & simple method works only if the user
*selects* an item in the scrolled down list (& then re-opens the list), in
which case the selected item will be the topmost item on move the window,
even if it wasn't the topmost previously; but if you scroll the 2nd combo
list down, but do *not* select anything new in it, I think that on moving
the window I should be able to get the new *scrolled* position to re-show.
So what I don't get is why the "CB_GETTOPINDEX" doesn't work, because it's
supposed to get the index of the topmost *showing* item on the list.
Oh, and taking a hint from you, I did also move the test into w32HEvent,
using your code in IDE as an example :)
