RE: separator and disable item in GtkTreeView

I think the properties is for all cells in the one column, not a cell in one row. So set property will apply 
to all cells, not just the disabled one.

The quick & dirty way to handle insensitive items currently is to have the custom cell renderer (or cell-data 
func) check whatever needs to be checked (a boolean "sensitive" column in the model, for example), and then 
set the "forground" & "background" properties of the text render to the insensitive/normal colors.

The "right" way is to subclass the renderers to implement a "sensitive" property, which overrides the drawing 
methods when the "sensitive" property is unset and draws the renderer properly.

The "best" way is to add the "sensitive" property to the current renders in GTK+.
