Hi,

I’m in need of a Gtk::TreeView in an application. I create the treeview  
and add it to my window (and the blank widget is indeed there) but I  
can’t seem to add anything to the treeview. I create a treestore, get  
the iterator and use that to add data, but it doesn’t seem to work, and  
the tree isn’t updated. Where am I going wrong?

Thanks

Hi,

there could different faults.

First you have to attache renderers to the view-colums. Than you have to  
take care, that the renderer get notified when the model get changed.

Take a look at the treeview-example at

[http://ruby-gnome2.sourceforge.jp/hiki.cgi?tut-treeview](http://ruby-gnome2.sourceforge.jp/hiki.cgi?tut-treeview)

If you have further questions, please send the relevant parts of your  
code.

Cheers
