Hello, I was looking at the GtkTextView widget and noticed that the widget has a concept of 'buffer coordinates' and 'window corrdinates'. I looked around but really couldn't find any documentation which explained them. Can someone point me to something that would explain these concepts. What I am ultimately trying to figure out is the following: If I have a Gtk- TextView and someone clicks on the text view with the mouse, how do I transform the mouse pointer coordinates into a location within the Gtk- TextBuffer so that I might perform a GtkText(Tag/Mark/Iter) operation.
