After reading a recent response from Corbin regarding table views
with non-selectable rows (feb 20), where he suggests returning nil
for the highlight color, I tried setting the background color of a
tableview to nil. I wanted to try and draw the tableview over
something irregular.
When I set the background color to nil the row highlight behavior
gets wonky, yes official term: wonky. Try it, you'll see what I
mean. :) Basically once a row is highlighted it remains highlight
regardless of change in selection. At first it look like the
tableview was allowing multiple selections (which is not turned on in
IB) but it appears to just be more of an display update problem.
How do I fix this? I do still want a highlight on the rows but when
the selection changes I want previous highlights to disappear.
On a related note, if I set the tableviews background color to
something with alpha < 1, the region under the table does not display
what should be under the table in the parent view (i.e. the window
background) instead it clips the region under the table showing
whatever is below the containing window. (does that make sense?)
Trying to restate more clearly, set the tableview background to a
color with an alpha of 0 and you see right thru the table view and
thru the window that contains it. It's an interesting effect but not
desired. I would expect that you would see through the tableview and
just see the background of the containing view or window.
bugs or are my expectations incorrect?
tia,
jeff
