Re: can't set background color for Gtk::Entry

[Bob Caryl <bob fis-cal com>]

Your code doesn't work because you are not modifying the object that actually renders the editable cell within the entry.  You need to retrieve the Pango layout for the entry and modify the background color attribute of the layout.  The following URL is a good place to start delving into this:

http://www.gtkmm.org/gtkmm2/docs/reference/html/classPango_1_1Layout.html

Hope this helps a little.
