tab to spaces conversion

[nimishm]

Are you working with plain text display OR with one of the 'word' type editors using true type fonts?

i am using Qt - a GUI language to output the display. this is just read the file line by line & displaying on a screen like object ( Listbox) Eg: like this one we are using here.

I still dunno how to get the no of spaces for a tab in the current program..
