Hi,
is there any way to insert a margin above the first row of an NSOutlineView
in a way that when scrolling (in my case Y-axis only) it will scroll the content
"through" its margin but when at topmost position, will leave the margin,
effectively offsetting the content and scroller downwards by the margin.
I can almost achieve the desired effect by returning an increased row height in
-outlineView:heightOfRowByItem:
by the desired margin for only the first row. Problem is the scroller still
spans the entire height of the view.
The background of this is that a certain new OSX version has a nice feature that
allows your window's contentView to span the entire window, underneath the title
and toolbar area (you probably have seen it in the WWDC keynote or technical
videos). The effect I'm after actually is implemented by NSTable/OutlineView
when the window doesn't use the full-size contentView and the scrollView starts
right below the title bar. However, I do need a full-size contentView and in
that case, I don't know how to achieve it.
So it might be plain obvious how to do this kind of offsetting (even in 10.9)
but I failed to find out how.
Before anyone suggests asking in the devforums, I did. It appears that any
technical questions by developers are completely ignored there. I'm beginning to
think there is a secret place where Apple directs people they want to hear
feedback from.
Regards
Markus
