I added a menu to an NSTextField and it works when first clicked,
but when the field is the first responder, the Field Editor takes
over with its own menu (as I should have guessed). My plan was
1. Insert custom field editor
2. Overide menuForEvent, capture the default menu, append my commands
It was looking promising, but two problems arose:
1. My NSTextView subclass only overrides menuForEvent, but other
crucial field editor tasks are lost. For example, the tab key inserts
a tab key rather then tabbing to the next field. Apple has help on
"subclassing NSTextView", but I could not find anything on the tasks
one needs to support manually to duplicate the default field editor.
2. I first created the field editor using code from Apple documentation:
- (id)windowWillReturnFieldEditor:(NSWindow *)sender toObject:(id)
anObject
{
if([anObject isKindOfClass:[NSTextField class]])
{ NSLog(@"getting field editor");
return [[BrowserFieldEditor alloc] init];
}
}
return nil;
}
I inserted a NSLog() line to watch this event and was surprised it
was called over and over again even when I was not initiating
editing. To avoid passing on multiple editors, I added one editor to
my window controlled and revised it to be
- (id)windowWillReturnFieldEditor:(NSWindow *)sender toObject:(id)
anObject
{
if([anObject isKindOfClass:[NSTextField class]])
{ if(!customEditor)
{ NSLog(@"getting field editor");
customEditor=[[BrowserFieldEditor alloc] init];
}
return customEditor;
}
return nil;
}
This worked OK, but my controller crashed when, as recommended, I
deallocated this custom editor when the window controller got
deallocated. Thus, I was confused on how to handle a custom field
editor.
