[MacRuby-devel] HotCocoa table_view and the doubleAction

[John Shea]

Hi Dave,

I am actually wrestling with a similar problem.

  I believe I have solved your problem, maybe you can solve mine ;-) ??

in the start method I placed:
       @my_table_view.setTarget(self)
       @my_table_view.setDoubleAction(:double)


and then later on a method:

   def double
     NSLog ("double")
   end


My issue is also delegating table updates to certain methods.

I noticed that tableview.setDelegate(self) did not do anything - and  
then I assumed that the TableDataSource is actually handling the  
delegate  - confirmed when I changed the numberOfRowsInTableView  
method to return the value 1.

But then I assume that I am not supposed to add my own tableView(tv,  
setObjectValue:anObject, forTableColumn:col, row:row) method to the  
HotCocoa TableDataSource file?

What happens if I have two tables in the one application with  
different delegated behaviour?

Am I supposed to get funky and add the different versions of the  
tableView methods to the data instance itself?
Is there a way to override the delegate dispatch to actually go a  
local class?

or do I setActions like in the double clicked example above?

Cheers and thanks,
J
