I've created an IB 3 equivalent of an old IB 2.x palette for a simple
NSView subclass. The only difference in this class and NSView is that
it draws a gradient background in its drawRect: method. The goal is to
use it as a "prettier" container for additional subviews.
On the surface, the plug-in works great and the Cocoa bindings
integration is spectacular, but...
- Contrary to IB 2, the new version won't let me drag subviews inside
my custom view. Even if I double click the custom view to "focus" its
contents, every control I drag over it is added as a sibling rather
than child.
- If I open a nib file created with IB 2 which contains one of these
custom views, IB 3 will display any children (subviews) embedded in
it, but won't let me move them or drag them out.
Is there a specific flag/method that needs to be implemented to
restore the above functionality?
A slightly less annoying limitation is the following: IB 3 remembers
that this NIB file required a custom palette. Although palettes don't
exist anymore, and IB 3 works with instances of the same view via the
new IBplugin, it keeps throwing an error message saying that the old
palette is required. Any way to kill this warning? No amount of re-
saving the NIB did the trick...
Thanks,
Gabe
