I have a .nib in which I define a window, Foo, and an unconnected view,

Bar has widgets in it, including a button that opens and closes a tray
off of Foo and some random text objects.
What I want to do is instantiate multiple copies of Bar, with different
text in the text objects, and pop them all into Foo so that
all of them appear in a list.
The easiest way to do this is to put your view (Bar) in its own nib.
Then your controller code can:
So the basic question is this: how do I
- load a view from the nib so that I get the formatting information,
- programmatically make lots of copies of it
Load the nib with the view multiple times.
- programmatically change the text, and
Have outlets from your controller to the text objects in Bar, and
set the text on them as you load them. (The outlets will be reset to the
new copies of the views when you load the nib again the next time.)
Since your Bar is now in a different view than your Foo, you
probably have to programmatically set the target and action of the Bar
button which opens/closes the tray now.
- programmatically put them all into the window?
Have a scroll view in the window (Foo) with a simple NSView inside.
Have an outlet to that inside view. As you load your Bars, add them as
subviews to that view, positioning them as you desire (presumably in a
column?), setting the view's bounds to fit its subviews as you do this.
The scroll view will automatically handle putting the scroller in
and sizing it appropriately to how much of the inside view is visible,
et cetera.
Can I?
Yep. Feel free to ask for more details if this isn't enough to get
you started.
Hope this helps,
