Is it the designed behavior that the disclosure triangle is not
vertically centered for a row specified as a group item?
I have a standard NSTextFieldCell (regular font size) for the
column that displays the disclosure triangle, the height of the
row has been tested with 13, 15 and 20. And in every case, the
disclosure triangle is not vertically centered.
Are you trying to create a Source List? When I create one, I set
the control size of the text cell used as the outline column's data
cell to the small control size. Doing so causes that cell's font
to be the correct size, which in turn causes the rows to be the
correct size, which in turn gets me rendering just like Mail.app.
Switching to a smallFontSize value leads to a better alignement but
why would the disclosure not be vertically centered in all cases?
I guess the answer is: file an enhancement request.
Thank you; I'll look into it (I already got your bug report).
