Selection in Textbox widget

Hello All,

I implemented selection mechanism, cut, copy, paste
and drag and drop of text from one text box to another
textbox or within the same textbox.

But there is a small problem. I didn't implement
selecting of text in good manner. So I want to know
how to change the background of text. There is one
attribute in paragraph structure called struct divnode
*background. Is it useful? 

In which fn I have to make changes to display
background for text.

Thank you.
