Hello,
1. What is the difference between IJFaceNodeAdapter.getElements and
IJFaceNodeAdapter.getChildren()? I'm not clear on this.
2. If I have XML like so:
<foo>
<bar val=1/>
<bar val=2/>
<quux val=3/>
<quux val=4/>
</foo>
And I want the outline to look like this:
Foo
+-bars
+-bar val=1
-bar val=2
+-quuxes
+-quux val=3
-quux val=4
I imagine I can play with getChildren and getElements to create a fake
sub-heirarchy. I can imagine that there may be some problems with this,
such as with the double-click listener and so on. Am I looking to do
something abominable, or is this somewhat standard? Thanks!
Thanks, Robert

1. The differences are documented in the method documentation in the
IStructuredContentProvider and ITreeContentProvider interfaces.
2. I wouldn't expect any problems with double-click as its only
implemented for known object types. If you do run across any
problems, just open a bug report. As for faking the tree hierarchy,
the DTD outline already does something similar for its "Group items
logically" mode, so it's not "abominable" at all.

Sorry, I didn't look that far down the interface chain. Thanks.

Awesome, thanks. Nitin comes to the rescue, again.
