digitalmars.D.learn - GtkD: How to respond to cell edit's?

Trying to setup a callback that will propagate changes from a 
cell(and editable GtkCellRendererText) to my model.

Can't seem to find any way to get the actual GtkCellRendererText

CellRendererText has an addOnEdited but I can't find a way to get 
the CellRendererTExt for a TreeViewColumn ;/

All the examples I've seen create the renderer programmatically, 
while I'm using glade.

https://github.com/gtkd-developers/GtkD/blob/master/demos/gtkD/DemoMultiCellRenderer/DemoMultiCellRenderer.d

While I could ID the cell renderer in glade, I'd like to get it 
programmatically.

Any ideas?

I should also mention that when I use an ID to do what I 
want(again, something I don't want to do), I also need to get the 
column that was edited. This is because I'm using one delegate 
for all the edits.


auto cb = delegate(string index, string text, CellRendererText r)
{
     // How to get the column of that we are editing? An index 
would be fine.
     writeln(index, " - ", text);
};

RT1.addOnEdited(cb);
RT2.addOnEdited(cb);
RT2.addOnEdited(cb);

Looks like I might have to use separate edit handlers ;/

I wonder if I can somehow template it so I can do something like


RT1.addOnEdited(cb!1);
RT2.addOnEdited(cb!2);
RT2.addOnEdited(cb!3);

without having to write a bunch of code to make it happen. Maybe 
there is a library function that can help?

Obvious it is easy when you have ID's, but this is meant for the 
original case where I'm not using ID's.

A far as i can tell using id's is the only option.

You can use a templated function as a delegate:

```
void cb(int column)(string index, string text, CellRendererText r)
{
	writeln(column, " - ", index, " - ", text);
}

RT1.addOnEdited(&cb!1);
RT2.addOnEdited(&cb!2);
RT2.addOnEdited(&cb!3);
```

Thanks! Hopefully that will help ease the pain and help avoid the 
large switch statement ;) It's strange one can't get the 
cellrenderers's from a column ;/
