can we override the drawing method of Gtk::Style

["Yogesh Arora" <yogesh ar gmail com>]

I do not want the widgets to be drawn in default way... so i want to have my own function which handle the drawing of widgets

This can be done in gtk+ by overriding method of GtkStyle

 

I tried doing the same with Gtk::Style class, so i make a class derive it from Gtk::Style & override one of the methods.

Then i set the style of one button with object of my class.

 

But my function is never overridden

 

Can we redefine the widget drawing function as in gtk+, or is there something wrong in the way i m trying to do it

 

i have atatched the source code files

Thanks
