GtkSpinButton in GtkTreeViewColumn?

[maurits rijk philips com]

Hi,

I was just wondering if it would be possible to have a GtkSpinButton inside a GtkTreeViewColumn. As far as I can see from the documentation and the source code it's possible to render a column with GtkCellRendererText and make it editable, but that will always create a GtkEntry widget in the cell you want to edit. I would like to have a GtkSpinButton for numerical cells. For example, I have a GtkTreeView that contains (x, y) coordinates I'd like to edit.
