I've got an NSTextField that the user can type a path name into.
When the user hits enter, I set $curr_path and call
$self->{'Window'}->display();
One of the items that regenerates itself at this point is an
NSTableView. It calls my numberOfRowsInTableView function,
which notices a change and recalculates the data for the table.
Then, my tableView_objectValueForTableColumn_row hands back the
values for the new version of the table.
All of this is working. What is not working is that I can't
figure out how to deSelect any row in the TableView that is
selected at the time of the regeneration. After all, the new
table may have totally different data; why should the same row
stay selected?
My latest attempt looked like:
# numberOfRowsInTableView - return number of rows
#
sub numberOfRowsInTableView {
my ($self, $tableview) = @_;
...
$curr_path = $default unless (defined($curr_path));
if (! defined($last_path{'Access'}) or
$curr_path ne $last_path{'Access'}) {
...
$tableview->deSelectAll();
...
When I run this, I get the message
Instances of class NSTableView do not respond to selector deSelectAll
Looking in the CocoaBrowser, I see:
deselectAll:
- (void)deselectAll:(id)sender
Deselects all selected rows or columns if empty selection is allowed,
otherwise does nothing. Posts NSTableViewSelectionDidChangeNotification
to the default notification center if the selection does in fact change.
As a target-action method, deselectAll: checks with the delegate before
changing the selection, using selectionShouldChangeInTableView:.
It seems like there should be a "serder" argument, but I dunno what to
use for it. Help?
