text selection

Hello,
I am new to the pango api. I want to use pango to draw
text(-boxes) with 
cairo (GUI for gaming). The textboxes are displayed to the
screen and 
the user should be able to select text from the text box
with the mouse 
and put the text curser to any location of the text.
The mouse coordinates are available as pixels. Does the
pango library 
provide an interface to do text selections for me? (i.e. a
function with 
the mouse coordinates as arguments which returns something
like: "Mouse 
is at text position X", and then I can access my text
string/char array 
at position X (text[X]) to get the char)

Kind regards
Ulrich

Pango does that.  See pango_layout_xy_to_index() and
friends:
