I have a cell which contains two other cells: a check box
(NSButtonCell) and a text field (NSTextFieldCell.)
I'm using this custom cell to draw rows in an NSOutlineView.
The problem I have is that double-clicking anywhere in my cell opens a
field editor to edit the text. It would make a lot more sense if the
double-clicking only worked when you double-click on the text field
within my cell. (Accidentally double-clicking on the check box and
having a field editor open over to the right of the mouse feels really
odd!)
The difficulty is that the double-click is handled by the
NSOutlineView, not the by the cell itself. The NSOutlineView simply
calls selectWithFrame:inView:editor:delegate:start:length: on the
cell, so the cell has no way of preventing the editing if the
double-click is in the wrong place.
Short of doing some very serious subclassing of NSOutlineView, does
anyone have any ideas on how to work around this?
Override -selectWithFrame:inView:editor:delegate:start:length: in your
custom 'PYCheckBoxAndTextFieldCell' class. Ignore the double-click if
it's not in the NSTextFieldCell's frame rect, otherwise allow the edit
(by forwarding the message to the NSTextFieldCell). It sounds like
you're not subclassing NSActionCell, but rather the NSTextFieldCell,
correct? Then just call -super instead.
