Laurent,
I haven't seen a response from one of the more knowledgeable members of
the list yet, so...

Hi all!
I have a problem which had me pulling my hairs for the last couple of
days.
I finally decided to ask here for help before I no longer have hairs
to pull
out!
Basically, I took the "ImagePopUpButton" class from
<http://iratescotsman.com/products/source/> to use it in a toolbar.
This is
a subclass of NSPopUpButton that reproduces the behavior of popup
toolbar
items in Xcode, for example.
After making some additions to the code (NSCoding protocol since
NSToolbar
seems to encode some items at some point), the popup button works fine.
However, when I choose to customize the toolbar, the icon doesn't show
up in
the customization palette. Only the title. If I remove the current
item from
the toolbar, then drag the one from the palette, it will appear
immediately.
I've checked everything I could think of, be it the min size of the
toolbar
item and its max size, the cellframe where the custom cell is
displaying
those icons, I can't for the life of me finding what is missing.
Anybody has any idea or ran into a similar issue? Code is available
upon
request to <mailto:email@hidden>.
How are you returning the toolbar item in
toolbar:itemForItemIdentifier:willBeInsertedIntoToolbar:? There was
some discussion a month or so back (see the thread "Subclassing
NSToolbar is *almost* really good") in which the same kind of issue was
happening. The fix there was to be sure to return a copy (i.e.,
[toolbarItem copy]) of the toolbar item in this method. Even creating
a new toolbar item and setting the view to be identical to the source
doesn't entirely work -- it has similar odd results (in the test code
I'm looking at, it usually disappears from the toolbar when the
customization palette is displayed). My guess is that creating a copy
of the view would work, but I'm not really in a position to test that
out right now.
Hope this helps.
chris
