NSTableView responding to first click in a panel

Question

I have noticed in the Interface Builder if I want to click on or drag from the Library panel, I only have to click on it once, even if the Library panel does not have the current focus.

I am trying to build a panel that behaves similarly.

Is there any simple way to let the NSTableView accept the click, even if the window does not have the focus?

Thanks.

Answer 1

Your view should override -acceptsFirstMouse: to return YES (or evaluate the event passed to you to determine what to return). You'll have to subclass NSTableView to do that of course.

Answer 2

Ok, I found the answer. Inside from awakeFromNib I call this: [self setBecomesKeyOnlyIfNeeded:YES];

It seems to do the trick. It's a little bit different from Interface Builder where the Panel actually gets the focus simultaneously with a single click, but doing it this way is just what I was looking for.
