I finally had a breakthrough! I'm not sure it's the "best" solution but it
works and hopefully will be instructive for others trying to do the same thing
connection views. There's a lot of steps (which is why I think it may not be
the "best") so I'll try to be as clear as possible.
1) when a user clicks their mouse in my subclasses NSTextField I send this
action:
BOOL theResult = [NSApp sendAction:@selector(notifyViewOfMouseDown) to:nil
from:nil];
2) my subclassed view has a method that executes when this action is sent:
- (void)notifyViewOfMouseDown {
NSDictionary *d = [NSDictionary dictionaryWithObject:self
forKey:@"view"];
NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
[nc postNotificationName:SRVIsSelectedChanged object:self userInfo:d];
}
This allows me to package up the view and send it along in a notification.
Packaging the view is **key** here because this is the view that needs to be
selected. My subclassed NSCollectionView is registered as an observer of this
notification. When it receives this notification I execute this code to update
the array controller with a new selectedObject
- (void)handleViewSelections:(NSNotification *)note {
View *v = [[note userInfo] objectForKey:@"view"];
int limit = [[self content] count];
for (int i = 0; i < limit; i++) {
NSCollectionViewItem *item = [self itemAtIndex:i];
View *thisView = [item view];
if ([thisView isEqual:v]) {
[item setSelected:YES]; //my subclassed
NSCollectionViewItem knows how to set itself as selected and update the array
controller
}
}
}
Boy, I'm glad I figured that out! I'm sure there are a lot more experienced
programmers than me out there so if anyone can think of a way I can do this
without so many steps I'd be glad to learn from them.
Jonathan, thanks for your suggestion. My subclassed NSTextField didn't respond
to superview. I wish it did, it would have saved me a step. To adapt your
solution I'd need to register each newly created view in my NSCollectionView
link that back to the NSCollectionViewItem that has the code to set itself as
selected and to update the array controller. I had to delete your reply from
this message to make it thru the listserve size
limit._______________________________________________
