Hello ,
I have still problems to receive notifications. This is my controller
methode
- (void)awakeFromNib
{
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(selectionChanged:)
name:NSTableViewSelectionDidChangeNotification object:nil];
}
And this is my selector in the same class
- (void) selectionChanged: (NSNotification *) notification
{
int row;
row = [projectFoldersTableView selectedRow];
if (row == -1) {
printf("Ok changed\n");
} else {
printf("No row\n");
}
} // tableViewSelectionDidChange
I should receive the notification for all tableviews but I'm
receiving nothing.
Do you have any idea?
Thanks,
Ferhat

Hi,
It sounds like you probably need to review:
Using a table view and delegate:
http://developer.apple.com/documentation/Cocoa/Conceptual/TableView/
TableView.html#//apple_ref/doc/uid/10000026
http://developer.apple.com/documentation/Cocoa/Conceptual/TableView/
Tasks/UsingTableDelegate.html
Using the notification mechanism:
http://developer.apple.com/documentation/Cocoa/Conceptual/
Notifications/Introduction/introNotifications.html#//apple_ref/doc/
uid/10000043
Additionally you might want to take a close look at all of the
table view delegate methods as tableViewSelectionDidChange is not
the only option and may no be the best depending on what you are
trying to achieve...
Hope this helps,
Wain

Hello,
I have another newbie question. Sorry but I didn't found a
document describing this problem:
To receive selection notification from a TableView you have to
implement this method:
- (void) tableViewSelectionDidChange: (NSNotification *) notification
{
}
But in which class should I implement this and how can I register
it to receive the selection event?
I have a controller (derived from NSObject) with an outlet
"tableView". I have connected it with my NSTableView.
Thanks,
Ferhat
