Custom Widget Problem

[Surya Kiran Gullapalli <skg fluent co in>]

Hi all,
I'm trying to write a custom widget, and i'm facing the following problem.

In the custom widget, on_expose_event virtual function, i'm drawing the widget.
Where i've to paint shadow.
So i've used this
=========
Gdk::Color c ;
c.set_rgb_p (1.0, 0.75, 0.75) ;
modify_bg (Gtk::STATE_NORMAL, c) ;

int x =  get_allocation().get_x() ;
int y =  get_allocation().get_y() ;
int w = get_allocation().get_width() ;
int h =  get_allocation().get_height() ;
get_style()->paint_shadow (m_refGdkWindow, get_state(), Gtk::SHADOW_IN, get_allocation(), *this, "temp", x, y, w, h) ; 
=========
Please see the attached image gtkmm1.png
I expect the colored portion will be filled up by the shadow. But not

then i changed the function call to some thing like this.
get_style()->paint_shadow(m_refGdkWindow, get_state(), Gtk::SHADOW_IN, get_allocation(), *this, "temp", 0, 0, w, h) ; 
Even then i did not get what i expected (gtkmm2.png).

what am i doing wrong here. 
Ideally i want the colored portion should be filled up by shadow. what is the best way to do.

Thx in advance,
Surya
