It is very interesting what all we can do with PyQt4. This widget is to select multiple options from the QCombobox. I made this widget in middle of my last software, where i have to put lots of options in the layout, the number of options may change. putting these may options as checkbox look ugly. So I think of creating a Combo-Box that can contains all the options. Chose the options using checkbox.  Bug  In ubutntu its only working with “plastique” style.
