Hi
I have a custom view inside a scroll view and all works nicely
except when the custom view's contents exceeds the depth of the
scroll view. The scroll bars don't appear. I created the scroll view
in IB from a standard widget and did nothing more than set the class
of default content view to my custom class.
I read the NSScrollView docs and the companion "Scroll View
Programming Guide for Cocoa" and notice that neither the contentView
nor the documentView are available from inside IB. I looked at the
different IB data views with scroll bars, checking what their
outlets are and tried setting mine up the same, but they must be
doing something behind the scenes.
What do I need to do to get the scroll view to notice when my custom
view exceeds it's depth?
Hi Ken,
I may be wrong, but I came across similar scrollview behaviour in
Tiger. IIRC, I asked about it here on cocoa-dev and got back that it
was a known bug. As I say, not sure if this is still the case.
My workaround was to uncheck the 'has scroll bar' in IB, then, in my
case:
id scrollview = [[tableView superview] superview];
[scrollview setHasVerticalScroller:YES];
[scrollview display];
The behaviour I was getting in my table view was that if you/the user
selected a visible row, then arrow keyed down, it would continue past
the bottom of the window but no (vertical) scroll bar would show and
you couldn't see what was actually selected.
HTH,
Ron
