Re: [Vala] [GTK+3] Setting colour for insensitive text

[tarnyko tarnyko net]

OK, I've got it, thanks to Valadoc.org. 

"Gtk.Widget.modify_text ()" is deprecated under GTK+3. One should use 
"Gtk.Widget.override_color ()" instead.
The trap is that no warning messages are displayed when using it. 

Here is the corrected sample part : 

var red = Gdk.RGBA ();
red.parse ("#ff0000");
[...]
entry.set_sensitive (false);
entry.override_color (StateFlags.INSENSITIVE, red); 

So simple...
