Hi,
I have two NSTableView in my app (tableView1 and tableView2).
If I select a row in tableView1 and then if I select a row in
tableView2, I want the row in tableView1 to be deselected.
For this I'm using [tableView1 deselectAll: nil], but it leads to
calling the delegate method again and leads to deselection of the
selected row in tableView2 also.
So this way both table view's stands deselected.
Is there a noble way to do it?
I'm not sure it's noble since my blood is red but:
Listing:
- (void)tableViewSelectionDidChange:(NSNotification *)notification
{
if ([[notification object] isEqual: tableView1] == YES)
{
if ([tableView1 numberOfSelectedRows]>0)
{
[tableView2 deselectAll:nil];
This will probably have the same problem; it will just stop after
doing the callback twice.
Let me clarify what is happening. Public "user" action entry points,
such as deselectAll: and selectAll:, need to inform the delegate that
the selection changed. If you use -[table selectRowIndexes:[NSIndexSet
indexSet] byExtendingSelection:NO] then you will avoid the
notification/delegate being notified, since it is assumed you *know*
what you are doing as the programmer.
