Anyone know how best to use multiple NSTextCell subclasses, in a table/
outline column?
When I use the dataCell... methods in NSTableColumn, NSTableView, or
NSOutlineView, it works great until I try to edit the cell, at which
point the cells never receive the edit/select actions. I've tried lots
of things but can't figure out what's happening, nor a better why to
do this overall.
In other words:
When I use the dataCellForTableColumn method, my table does display
the different textcell subclasses returned. But when I send the table/
outline [self editColumn:1 row:[self selectedRow] withEvent:theEvent
select:YES] message it seems to get lost -- my specified cells don't
receive an editWithFrame/selectWithFrame action. If I remove this
method and only use one cell class in the column, it works as expected.
- (NSCell *)outlineView:(NSOutlineView *)outlineView
dataCellForTableColumn:(NSTableColumn *)tableColumn item:(id)item {
if ([item isKindOfClass:[Project class]]) return projectTextCell;
if ([item isKindOfClass:[Action class]]) return actionTextCell;
if ([item isKindOfClass:[Item class]]) return itemTextCell;
if ([item isKindOfClass:[Note class]]) return noteTextCell;
return nil;
}
The point of this is to breakout my cell designs for efficiency and
comprehension. But so far it's just making me nuts. ;-).
Any suggestions??
