I would like to track the selection of a NSTextView continuously, but I only succeed to get the change when the selection finishes changing using:
- (void)textViewDidChangeSelection:(NSNotification *)notification {
}
Is there a way to track selection changes continuously? Any help is greatly appreciated. Thanks
I succeeded to solve the issue by subclassing NSTextView and overriding the following method:
-(void)setSelectedRanges:(NSArray<NSValue *> *)selectedRanges affinity:(NSSelectionAffinity)affinity stillSelecting:(BOOL)stillSelecting {
[super setSelectedRanges:selectedRanges affinity:affinity stillSelecting:stillSelecting];
if (stillSelecting && [self delegate] && [[self delegate] respondsToSelector:@selector(textViewDidChangeSelection:)]) {
NSNotification *note = [[NSNotification alloc] initWithName:@"TextViewSelectionIsChangingNotification" object:self userInfo:nil];
[[self delegate] textViewDidChangeSelection:note];
}
}
This seems to me a good solution, it works well. Thanks.
