distance in pixels between 2 GtkTextIters

["Nick Gravgaard" <me nickgravgaard com>]

Hi,

I'm trying to figure out how to get the distance in pixels between 2
GtkTextIters. At the moment I'm using gtk_text_iter_get_slice() to get
a char pointer, and then using gtk_widget_create_pango_layout() and
getting the width from that using pango_layout_get_pixel_size(). The
problem with this approach is that it doesn't take into account any
bold and/or italic text that might occur between the 2 GtkTextIters.

What's the solution to this problem?

Thanks,
Nick
