Good Afternoon,
I'm trying to perform a relatively simple thing and having a terribly
complicated time with it. Some of you might recognize this issue from
the PB list, and I apologize for cross-posting, I didn't realize there
was a list for cocoa specifically until later in the day.
The behavior I am attempting to produce:
When the user types in a cell within an NSTableView, I want to know
what is being typed.
The process I have followed thus far:
I have created a window that contains an NSTableView.
I create a datasource object and make this DS my dataSource for the
NSTableView,
as well as the delegate for the TableView.
I can receive event information for the NSTableView pertaining to
keyDown,
but once I enter the cell itself, I lose the ability to know what has
been typed.
The problem that I think would solve the issue:
There is the method: - (void)textDidEndEditing:(NSNotification
*)aNotification; which I have implemented in MyDataSource, which should
be NSLog[ing] "End Edit" when the user hits return in the cell, but for
some reason this event is not exposed to MyDataSource for delegation (
or rather it's not being called when I stop editing the cell).
I know that NSCell ( or more specifically NSTextFieldCell ) can tell
me that editing has ceased, but I don't know how to insert a subclass
of that particular item into my table. I think that this might be the
wrong approach regardless, as it seems like the NSTableView should know
when a cell edit has stopped, or when a key has been pressed in one of
it's columns->cells->text fields.
Someone [Thanks Jonathan] also suggested that an NSFormatter might
work, although I don't really care about the contents of the cell, just
whether or not the return key was pressed, ( or perhaps cmd+delete in
the future.. )
Thanks for any help,
-Thomas
