What I can't do is to tie any outlets to the toolbar items or set
any actions or targets for the items. IB's interface doesn't even
let me select the items individually, and I cannot assign my own
identifiers to them.
At runtime, when the nib is loaded, the pre-installed items are
there but they have been assigned identifiers which are UUID
strings. My delegate gets called and I can add additional custom
items just as I would if I were doing it all in code, but for the
nib-supplied items, I get nothing. Since the identifiers are
assigned UUIDs somewhere there's no way to know what identifier to
use to retrieve an item from the bar and fix up its target/action.
The whole ability to set up toolbars in IB appears to be useless to
me.
So before I ditch it all and go back to doing it the harder-but-
saner way, can anyone point me in the direction of something that
will help me make any sense of this?
The identifier thing is annoying. There isn't any way to set your
own. The best alternative seems to be to create an outlet for each
toolbar item you need to refer to in code, and hook them up in IB.
Then you can extract the identifier via the outlet if you need it.
You could implement NSToolbar's toolbarWillAddItem: delegate method,
for example, and build a collection of toolbar items.
The toolbar that IB shows you in its owner window is actually the
default set of items, and you can't select them individually there.
To get the full set of items, you click on the toolbar once to
select it, then again so that the "allowed items" sheet slides out,
and you can select individual items in that sheet. Click once to
select the toolbar item, click again to select the underlying control.
There were some bugs in IB's toolbar handling, where it wouldn't
save the toolbar after you changed it. I'm not sure if that bug is
still in the shipping 3.1 version. (The only workaround I found was
to put a separator item at the beginning and the end of the toolbar.
Then it seemed to save OK.)
HTH
The bug seems to be there still.
