Don't know why you're having trouble with #0...
For #1, this is fairly easy. Set an NSPopUpButtonCell as the dataCell
of the NSTableColumn you want the popup in. For your dataSource, the
objectValue for that column should be an NSNumber that is the selected
item index for the popup.
For #2, you can create controls programmatically. The typical
constructor for a control takes a frame rectangle as its argument. You
then need to add the control into a view hierarchy using addSubview().

Since my previous question was so quickly answered, let me ask for
some help
in approaching my next project. I really have three questions
concerning
Cocoa Java.
0. I have an NSTabView. I call tabview.selectNextTabViewItem() or
something
like that and nothing happens. Am I missing something? I expect the
next
tab to appear. This is with 10.1, by the way, as I have not yet been
able to
upgrade.
1. Is there a way to create a table with different types of cells,
such as
PopUpButtons?
2. I want to have an window to allow me to edit some of my data files
but the
exact fields in the file are not known until runtime. Basically, it's
like
a database where the user can select the type of fields etc. How does
one
go about dynamically generating widgets in a window? The only thing I
know
how to do dynamically is a datasource for a table, and I think I saw
methods
for changing the number of rows etc.
To tie 1 and 2 together: one interface I was thinking for adding
entries to the
database is to have a large table, but I'd like some of the columns to
be
popupbuttons to allow selection from only a limited set of options.
thanks,
niko
