Hello...
window). This works great _except_ that when I resize the scrollable
area, IB insists on placing the scroll bar at the bottom of the
document area, rather than the top. I've looked all over the place,
but can't seem to find a command to tell the stupid scroll bar to go
to the top of the document. Hopefully there's something simple to do
in IB to force this--if not, I guess I'll have to find out where the
hidden code is that IB generates to make these interfaces.
What is happening is that the scroll view will always choose to go
toward the orgin of the content view in this situation. The normal
coordinate system of NSView places the origin in the lower left
corner of the view, thus NSScrollView tends to go to the "bottom" of
the content view.
The most simple solution is to make the content view of the
scrollview a flipped view, assuming you are using a custom NSView
subclass inside the NSScrollView and it won't cause other problems
with the rest of the code in your custom NSView class.
Otherwise you can just send a scrollRectToVisible: message to the
content view and provide the rect of your top left cell.
Oh, and as long as I'm asking, I'd also love it if, when I tab into
a field that's not visible in the clip area, the view would update
itself to place that cell into view. I'm sure there's a way to do
this too, since I've seen it done, but I can't figure out how.
You can probably override editWithFrame:inView:editor:delegate:event:
in an NSCell subclass to do something like this (untested, typed in
mail, etc...)
- (void)editWithFrame:(NSRect)aRect inView:(NSView *)controlView
editor:(NSText *)textObj delegate:(id)anObject event:(NSEvent
*)theEvent
{
[controlView scrollRectToVisible:aRect];
[super editWithFrame:aRect inView:controlView editor:textObj
delegate:anObject event:theEvent];
}
Hope that helps,
Louis
