In MacOS 10.8 I have a window that contains two NSTableViews
clipListTable and
tablesTable
In the data model. tablesTable has a to-many relationship with the selection of
clipListTable
In the window controller awakeFromNib I set the window controller to be the
delegate of the two tables
- (void) awakeFromNib
{
[super awakeFromNib];
[[self tablesTable] setDelegate:self];
[[self clipListTable] setDelegate:self];
}
The window controller has a delegate procedure tableViewSelectionDidChange:
#pragma mark - NSTableViewDelegate methods
- (void)tableViewSelectionDidChange:(NSNotification *)aNotification
{
id tableCandidate;
tableCandidate = [aNotification object];
DLog(@" tableCandidate %@", tableCandidate);
DLog(@" clipListTable %@", [self clipListTable]);
DLog(@" tablesTable %@", [self tablesTable]);
if (tableCandidate == [self clipListTable]) { //Change in
clipListTable
NSArray *selectedObjects = [[self videoClipArrayController]
selectedObjects];
if ([selectedObjects count] == 1) {
VideoClip *clip = [selectedObjects lastObject]; // There should
only be one...always.
}
}
else if (tableCandidate == [self tablesTable]) { //Change in
tablesTable
NSArray *selectedObjects = [[self tableArrayController]
selectedObjects];
if ([selectedObjects count] == 1) {
Table *tab = [selectedObjects lastObject]; // There should only be
one...always.
}
}
}
If i select a row in the clipListTable, the log reads:
2012-11-17 10:29:38.760 Roboplasm[82172:303] -[MediaWindowController
tableViewSelectionDidChange:] tableCandidate <NSTableView: 0x1006f20b0>
2012-11-17 10:29:39.727 Roboplasm[82172:303] -[MediaWindowController
tableViewSelectionDidChange:] clipListTable <NSTableView: 0x105407260>
2012-11-17 10:29:48.089 Roboplasm[82172:303] -[MediaWindowController
tableViewSelectionDidChange:] tablesTable <NSTableView: 0x1006f20b0>
and the Change in tablesTable branch gets executed
If I select a row in the tablesTable, the log reads
2012-11-17 10:32:29.463 Roboplasm[82172:303] -[MediaWindowController
tableViewSelectionDidChange:] tableCandidate <NSTableView: 0x1006f20b0>
2012-11-17 10:32:30.131 Roboplasm[82172:303] -[MediaWindowController
tableViewSelectionDidChange:] clipListTable <NSTableView: 0x105407260>
2012-11-17 10:32:30.807 Roboplasm[82172:303] -[MediaWindowController
tableViewSelectionDidChange:] tablesTable <NSTableView: 0x1006f20b0>
and the Change in tablesTable branch also gets gets executed. In other words
aNotification always reports the tablesTable as the tableCandidate no matter
what table i click on in the window.
How can I respond to a selection in the clipList Table?
