Setting the background color of a GtkFixed

[Tapan Satpathy Ansuman-A19108 <ansuman motorola com>]

Hi,

I want to create a Frame in which I can put many child widgets.

For that I create a Frame and put a GtkFixed inside this. I want to add some colours dynamically to the 
Parent Frame. But gtk_widget_modify_bg(...) doesn't seem to be working on GtkFixed.

Is there any method to do so? Or should I use some other widget instead of GtkFixed ?

Regards.
