Re: Font selection panel

Hi,
I looked more closely at the code you provided and here are some observations.

Yes in your code I need to set button2 as disabled initially - call
gtk_widget_set_sensitive( button2, false ); when the program starts.
Then when the user changes the font in any way (i.e. (s)he presses
arrow key anywhere),
the button becomes enabled.

IIUC, in GTK3 it may be possible with
https://developer.gnome.org/gtk3/stable/GtkFontChooser.html#GtkFontChooser-font-activated
signal, but if I read the docs correctly there is no equivalent for GTK+2.

Yes, this part I understand.

That's weird - I definitely see the deprecation warning in the GTK+2 docs -
see https://developer.gnome.org/gtk2/stable/GtkFontSelection.html#gtk-font-selection-set-font-name
for the reference.

Thank you for the code and Happy New Year!!
