Re: Font selection panel as part of notebook



Eric,
Why am I breaking the design?
Is it illegal to do?

Thank you.

Igor,

It sounds like you are determined to hack at this. I would recommend the newer GtkFontChooserWidget but OK. The PangoFcFamily* isn't much help. You need to get your widget pointers and setup up callbacks on your treeviews. Maybe all you need is to connect a "row-activated" to know if the user clicked on a row. To do this you need to find your pointers. If you use gtk_container_forall() you can find them. When doing this you are breaking the design of the font selection widget. It is poor practice. It might be just what you need though.
