Re: [MacRuby-devel] HotCocoa table_view and the doubleAction

Hi Dave,

thanks for your answer.

I haven't had any problems using delegate methods. For example I do:

        @tableView.delegate = self

and define a delegate method:

        def tableView (table, shouldEditTableColumn: c, row: r)
                false
        end

Thats the first thing I tried - but for the tableView(table,  
setObjectValue .. method which was not delegated to.

Unfortunately as it was the first one i tried (because i wanted to  
edit table fields) -  that sent me on a wild goose chase trying to  
figure out why the delegate was not working as it was in all of my non- 
hotcocoa code.

So thanks for pointing out that some of them are actually delegated to.

For me:


  #works
  def controlTextDidChange(notification)
      NSLog("controlTextDidChange #{notification.object}")
      NSLog(@mv_table_view.selectedRow.to_s)
  end

  #works
  def tableView(tv, willDisplayCell:cell, forTableColumn:col,  
row:the_row)
   NSLog("willDisplayCell")
  end

  #works
  def tableViewSelectionDidChange(notification)
    NSLog("tableViewSelectionDidChange")
  end

#is not delegated to
  def tableView(tv, setObjectValue:anObject, forTableColumn:col,  
row:row)
    NSLog("tableView setObject")
    #edit data here
  end

#is not delegated to
  def numberOfRowsInTableView(tv)
    NSLog("numberOfRowsInTableView")
    0 #test 0
  end

#is not delegated to
  def tableView(tv, objectValueForTableColumn:col, row:row)
    NSLog("objectValueForTableColumn")
    val = "richard"
  end


I could probably do a work around with controlTextDidChange - but it  
seems a bit dodgy.
Or another option would be to edit not within the table, but in  
another form.

I suppose there is some simple explanation - but I am missing it for  
the moment.

Cheers,
J
