Q:
How to display rich text in a gtk.MenuItem label?
I would like to display rich text in a gtk.MenuItem(), e.g. displaying bold text. So far I have only found that one could pass in a string.
Is it possible to display rich text in such a label? If so, how?
If not, how appalling that would be! :)
Thanks.
