[MacRuby-devel] get and set a checkbox in tableview

[James Chen]

In tableView:objectValueForColumn:row:, return ruby true or false should be
enough to make the checkbox checked or unchecked. Be sure to check the
tableColumn.identifier so that you're actually dealing with the checkbox
column.

Normally you don't have to do anything
in tableView:setObjectValueForColumn:row to check/uncheck the checkbox. When
the user clicks the checkbox, this method is called and you could persistant
the object value. Do check the tableView:setObjectValueForColumn:row too.

Here's some real snippet: http://bit.ly/m98G2P

Hope this helps.
