Re: Editable GtkCellRendererText, troubles with the GtkEntry...

[Axel FILMORE <axel filmore gmail com>]

Probably I'll have to implement my own text renderer and probably a 
GtkTextView is a better choice :

http://s16.postimage.org/8zivb78ph/icon_edit.png

Using a GtkFixed and then a GtkTextView with word wrap :

                Gtk.Fixed fixed = new Gtk.Fixed ();
                this.add (fixed);
                fixed.show_all ();

                Gtk.TextView icon_edit = new Gtk.TextView ();
                icon_edit.set_size_request (72, 16);
                icon_edit.wrap_mode = Gtk.WrapMode.WORD_CHAR;
                icon_edit.show_all ();

                fixed.put (icon_edit, 95, 200);

Not too bad :-P

Probably I'll have to use gtk_text_view_im_context_filter_keypress () to 
filter particular keys and it should work.
