OK, lets solve the problems one at a time.

Problem #1.
I'm creating a panel similar to font selection dialog box.
In the constructor of this panel I call pango_font_description_new().
Then I read the data about the font from configuration file and
should change the attributes of the empty font to reflect them.
And the update the text in the preview.

Now here are 2 questions:
1.Am I right in the assumption that I need to use pango_attr_strikethrough_new()?
2.If the answer to  #1 - yes, then is there an example of how to call it?

Thank you.
