Hi,
I need to draw the background of a single row in a tableview. This
row is not the selected row, and it changes often. I have more or less
got it working but it seems like a bit of a hack so I'm wondering if
there is a better way. I've also checked various examples but most
want to draw the selected rows differently, not an arbitrary row.
At the moment I subclass the cell for each of the columns of the view
( same subclass). In my delegates objectValueForTableColumn I set a
variable 'shouldDrawRow' to true if that is the 'special' row I want
to draw myself.
In the cell subclass I override drawInteriorWithFrame and check to see
if this value is set in my delegate and if so call a delegate method
to draw the background first.
This seems like a real hack as it assumes that drawInteriorWithFrame
will be called straight after objectValueForTableColumn. This is sort
of reasonable because the cell is reused all the time so it 'works'.
The other problem though is I want to draw the ends of the rows
differently to the middle ( thin rounded rectangle ) and
drawInteriorWithFrame only gives me the rectangle to draw in. I've got
no way of finding out which column it is. Again it will work because
the columns won't change so I can hard code some values.
However I'm thinking there must be a better way. What I really need is
some way of finding out the column and row of the cell about to be
drawn, but I can't see it. Am I missing something?
thanks!
Peter
