Hi,
I have the outlineview cell which is a subclass of NSActionCell.
I can set its target and action with setTarget: and setAction:.
But it invokes the method on single click.
Whereas I want the method to be called only on double click, I have
seen the docs and there is no method like setDoubleA
Here super-imposition means that text appears garbled and is put over
the previous text.
