Hi, all. I wonder whether I've found a possible bug with the Cocoa
GUI system. I have an NSTableView that I subclassed for delete-key
and escape-key support, amongst other things. For some reason after
I put the table view inside of a tab view (as the only child view of
the first tab view item, I might add) the default (untouched!) arrow-
key support stops working.
My key-handling code is as follows:
- (void)keyDown:(NSEvent *)event {
consumedKeyDown = NO;
[self interpretKeyEvents:[NSArray arrayWithObject:event]];
if (!consumedKeyDown) [super keyDown:event];
}
- (void)doCommandBySelector:(SEL)selector {
consumedKeyDown = [self tryToPerform:selector with:nil];
}
(Where consumedKeyDown is a BOOL instance variable set to NO in -
awakeFromNib.)
Switching the table's class back to a regular table view solves the
problem, as does commenting out the one line in -doCommandBySelector:
I haven't been able to find anything in the docs or in the archives
to explain the lack of arrow key functionality that I'm
experiencing. Does anyone have any pointers? Is the tab view
interfering with the arrow keys somehow?
The keyboard nav for tableviews is handled in [super keyDown:].
Chances are, you aren't calling it. You may want to special case those
keys to let them through.
