Good question -- if you want the double action to be called, you have
to set the app controller to be the table view's target, not just its
delegate. You can, of course, make the connection in IB; you don't
have to use setTarget:.

Perhaps you have a good reason, but from your description, and being
used to using Mail, I'd expect the lower part to display the content
with a single click.
Have you used setTarget: and setAction: to coordinate this double
click event?

Hello all,
I'm trying to construct a Cocoa app that mimicks the Mail
application,
with the difference
that it's not especially intended for mails : one the upper part a
list of
titles, and on the lower
part exactly one title&text is shown. Double-clicking on a title in
the
upper part makes the corresponding text displayed in the lower part.
I implement the upper part as a NSTableView subclass (which I call
UneditableTableView), with one column and all rows uneditable (by
setting
the tableView:shouldEditTableColumn:row:
method to always return NO in the delegate). That main app controller
a signature of signature -
(void)updateLowerPartAfterSelectionInUpperPart
that makes the lower part display
the text associated to the title just selected. Finally, in some
place in
my code
I have the line
[uneditableTableView
setDoubleAction
:@selector(updateLowerPartAfterSelectionInUpperPart:)];
Unfortunately, this doesn't work : although the rows are indeed
uneditable and I can select
any one of them, the "updateLowerPartAfterSelectionInUpperPart"
method is
never called
when I double-click on a title. Does anyone have any idea of what I
should
do to fix this?
TIA
,
Ewan
