Spoke too soon, *sigh*

I've rewritten my project without using Mac::Dialogs. Now its just a window
with embedded controls (and I handle highlighting the default button, etc.)
With the popup menu example Alan kindly supplied I've got a working window
(buttons and all) so long as the window contains only controls (popups,
buttons and checkboxes). I have a single 'hit' hook to toggle the
checkboxes, and a 'hit' routine for OK and Cancel. I leave all the other
control hooks alone (they seem to work fine with the default behavior).

I added a list to the window recently, and it too works so long as I don't
give it a hook for 'click'. Since the default behavior is fine for the list,
that's OK by me, although I was surprised that setting the hook seemed to
result in the list 'click' hook being called for any click in the window
that was not within another control (i.e. all clicks on blank window content
went to the list 'click' hook.

Now I've added back the text fields I had in the original dialog version
(using $win->new_textedit) and suddenly I'm broken. Here's the behavior:

- If I do not override any hooks for the textedit object then text entry,
tabbing between fields, etc. all work OK. However, all controls start having
odd behavior. For example, when clicking buttons the button does not
highlight, but on mouseup the action for the button occurs. When clicking a
popup the menu does not popup immediately. Instead the menu pops up after
the mouseup and selects the menu item that would be positioned under the
location of the mouseup.

- If I override the click hook on the textedit items then I see why the
above happens. That hook gets called first for _every_ click in the window,
regardless of location. With my hook all controls stop working (never see
any clicks). 

I'm hoping I didn't read things closely enough, because that seems like its
wrong. Surely the TextEdit should only gets its own clicks?

For what its worth, I have a couple of window level hooks. A cursor hook
which does mouseover help text, a key hook to handle default buttons (Esc,
Return, etc.), and an idle hook which watches for changes and populates the
list on the basis of other selections in the dialog. I understand that the
'key' hook will eventually need to pass keys to the textedit fields (since
it with it active the textedit fields won't take keystrokes). However, I
disabled all these hooks and get the same behavior.


All suggestions appreciated,

Thanks,

Alex
