Underline in Gtk Actions

[Jonathan Lane]

I have a few GtkActions tied to toolbar buttons and menu items.  In  
the menu items, how do I get underlined characters in the label?

For instance, if the Label of the GtkAction is "_Log Output", it  
simply displays the underscore before the 'L'.  If in the menu item I  
uncheck "Use action appearance" and specify the label there (and check  
"Use Underline"), it will show correctly in the glade project, but not  
in the program.

What is the correct procedure to achieve this?

Thats a good question - I have to check - its also possible that its
a bug or unimplemented in GTK+ (I think that there is already a bug with
menu items not rendering the accelerator indicator for accelerators specified
via actions).

Out of curiosity, the "use-underline" property is disabled in Glade with
"use-action-appearance" ?

Maybe "use-underline" needs just to be explicitly set - and will use
the "label" or "short-label" property of the action and render the
mnemonic underline (if its impossible with Glade, try it once by
hand in the xml with GtkBuilder, if it works then its an easy to
fix bug in Glade).

Cheers,

Yes, the property is disabled if you select Use Action Appearance.  I  
was saying that I tried unchecking "Use Action Appearance" and  
manually setting the label in the menu item and it still didn't draw  
the underline.

Ah, that does work.  Yay for easy bugs :)
