Text Widget

[Or Goshen <oberon netvision net il>]

Hello

Is there a way to make a tag in GtkTextView unselectable ?
So the user wont be able to select it while dragging the mouse , only the text surrounding it ?
I wonna create a new widget and GtkTextView will be it's parent , the unselectable text is a feature i need to implement .
The widget should look like this : 
2 lines of editable and selectable text , and then 2 lines of unselectable and uneditable text.
makeing a text uneditable is easy ( there is a property for that ) , but how do you make it unselectable ?
