tree expand

[srinivas <srinivas comodo com>]

thanks for reply;

          i saw the tutorial, i had one doubt, actually i want to
display like in the given fig. but using gtk tree view we have to add
pixmaps with text, is there any way by which we can get this image
format.i.e with when mouse pressed on '+' it has to expand and if
pressed on '-' it has to collapse.i want to display as tree
hierarchy.(sorry but iam new in this.)

thanks;
