Thanks for help...
I already implemented the ContextMenuEvent.
1. But the Combo Box should appear only on selecting some particular item
in the PopUp Menu.
2.How to close the combo box after selecting an item?
Cheers

It's already answered in my other post, I think :)...

When an item has been selected, that's easy, because you could use the emitted
activated() signal and close() the combo-box in a connected slot.

The question is when to close the combo-box if NO item is selected. I'd use
the focusOutEvent().
