Thanks Havoc,
I am new to gtk+ so also to pango and I read Pango is the thing
to use for application using fonts etc . I am designing a UI for
a application (a user interface for a mediaplayer) on Linux. I have
so many text strings to display ,with various font and color, so that it 
looks attractive :).

I calculate the max ascent/descent returned for each string so that
I can allocate the space for each string propely in a table kind of thing. 
The reason of using the PangoMetrics is only the name suggests
I can get all the above parameters from it only .

Thanks again . I think I need to study more on Pango.
