Hi,
Thats correct.
But in My application i have a table view in which i need to take
some actions.
In short i can say that My application should behave like iTunes
where in it just slightly changes the color of selected playlist in
oulineview but still allows doubl-click and slection highlighting on
the table view.
I think what you'll have to do is use a custom cell for the table view.
any idea?

That is happening because the outline view is loosing it's it's
first responder status.
You can refuse to resign the first responder status by overriding -
(BOOL)resignFirstResponder
and returning NO
Except that is likely to cause the rest of your user interface to
stop working in a useful way (i.e. text fields etc can't become key).

Hi All,
I am writing a coca application in which i use NSOutline view for
Navigating
between different view like iTunes.
So when i am clicking on the ouline view contents, the contents are
highlighted in the blue.
If i click on any other view other than the ouline view, ouline view
content
which i had chosen is becoming light gray colour.
Is there any way in which i can still retain blue colour in the
selected
otline view content?
I handle this by subclassing the outline view and implementing:
- (void) highlightSelectionInClipRect:(NSRect) clipRect
{
[super highlightSelectionInClipRect:clipRect];
NSRange rows = [self rowsInRect:clipRect];
if( NSLocationInRange([self selectedRow], rows))
{
NSRect sr = [self rectOfRow:[self selectedRow]];
[[NSColor selectedTextBackgroundColor] set];
[NSBezierPath fillRect:sr];
}
}
Here I'm just using the selected text colour the user has set in the
system prefs, but you can use whatever you want.
Also, in 10.5 there were some new methods added that allow you to
set a highlighting style which might make this approach unnecessary,
but off the top of my head I don't know exactly the details as I'm
not at my main computer.
hth,
Graham
