I only have a single column in my NSOutlineView.

I need the height of a row an of an item displayed when the
disclosure triangle is clicked to be based on the width of the cell.
I can get the indentation level by doing:
NSInteger level = [outlineView levelForItem:item];
and the amount that is indented per level by doing:
CGFloat indentation = [outlineView indentationPerLevel];
Asking for the width of the column does not return the same width
of the bounds parameter when drawInteriorWithFrame is called for
my cell.
What looks like could work is to get the frame of the
NSOutlineView and then subtract the width of the frame by:
indentation * (level + 1)
but this doesn't seem like it should be the right answer.
There doesn't seem to be a method I can call to obtain the bounds
that will be passed into drawInteriorWithFrame for my cell. Have I
missed something?
-frameOfCellAtColumn:row: is exactly what will be passed to your
cell.
Unfortunately, this does not work as calling this function causes
heightOfRowByItem to be called. So, an endless loop is entered.
Yes, of course...since it needs to know the height, but it does answer
your question of how to obtain the bounds that are passed to
drawInteriorWithFrame:.
I just need to know the width so I base the height on the width.
For that, you want to use -cellSizeForBounds: -- pass in a large
height, but a constrained width. Use a width that is equal to the
[tableColumn width] minus indentation * (level + 1) ---- although, the
actual value that outlineview uses for indentation is dependent on
some internal logic (ie: if you are using "group rows", or the "source
list highlighting style"). But, this should give you a value that is
fairly close to what you want.
