My app has several different window types with different toolbars and
toolbar items. The problem is that you can drag the default set of
icons from window A's Customize Toolbar pane into window B's toolbar.
This results in window B having an empty toolbar. I tried this in
other cocoa apps (Mail, Xcode) and the same thing happened. I'm
guessing this is a known issue, is there a workaround for it?
I think you can resolve this issue by using the delegate to restrict
the items that the toolbar allows.
Something like the following should do the trick, I think. (I can't
say that I can speak from experience, but I think this would work. And
the usual email-written disclaimers apply.)
1. Create your toolbars using unique identifier for each window type:
e.g.,
NSToolbar * toolbar = [[[NSToolbar alloc]
initWithIdentifier:@"toolbarA"] autorelease];
// add stuff, configure etc...
// set the delegate
[windowOfTypeA setToolbar:toolbar];
toolbar = [[[NSToolbar alloc] initWithIdentifier:@"toolbarB"]
autorelease];
// add stuff, configure etc...
// set the delegate
[windowOfTypeB setToolbar:toolbar];
2. Either have two different delegates for the toolbars, or have one
delegate that differentiates the toolbars by the identifier. If you
have two different delegates, just return the appropriate array of
identifiers from the delegate. If you have one delegate for both
types, you can do something like the following:
- (NSArray *)toolbarAllowedItemIdentifiers:(NSToolbar*)toolbar;
{
NSString * identifier = [toolbar identifier];
NSArray * result = nil;
if ([identifier isEqualToString:@"toolbarA"])
result = [NSArray arrayWithObjects:@"itemA-1", @"itemA-2", nil];
else if ([identifier isEqualToString:@"toolbarB"])
result = [NSArray arrayWithObjects:@"itemB-1", @"itemB-2", nil];
return result;
}
