I have an NSOutlineView and I want it to act very similar to how
ProjectBuilder's "Files" view acts. You can control-click an item in
the view and enter "Rename" mode. This causes the outline view to
enter edit mode for that table column. You type the new name in and
hit the return key. The item's new name is set and the item remains
selected but no longer in edit mode.
The default behavior of NSOutlineView when a user hits the return key
while in edit mode is to advance to the next item in the list and
initiate editing of that item. How can I make NSOutlineView behave
like ProjectBuilder's outline view instead?
Thanks in advance for your advice!
from the OmniAppKit source code:
- (void)textDidEndEditing:(NSNotification *)notification;
{
if (flags.shouldEditNextItemWhenEditingEnds == NO &&
[[[notification userInfo] objectForKey:@"NSTextMovement"] intValue] ==
NSReturnTextMovement) {
// This is ugly, but just about the only way to do it.
NSTableView is determined to select and edit something else, even the
text field that it just finished editing, unless we mislead it about
what key was pressed to end editing.
NSMutableDictionary *newUserInfo;
NSNotification *newNotification;
newUserInfo = [NSMutableDictionary
dictionaryWithDictionary:[notification userInfo]];
[newUserInfo setObject:[NSNumber
numberWithInt:NSIllegalTextMovement] forKey:@"NSTextMovement"];
newNotification = [NSNotification
notificationWithName:[notification name] object:[notification object]
userInfo:newUserInfo];
[super textDidEndEditing:newNotification];
// For some reason we lose firstResponder status when when we
do the above.
[[self window] makeFirstResponder:self];
} else {
[super textDidEndEditing:notification];
}
}
