[Qt-interest] Adding menu for tabwidget

[rajasekharan]

Yuvraj,

Why do you want to implement the menu using a tab in a tabwidget?  I'm 
asking because users are not used to having menus pop up out of tabs 
generally, there may be a better, easier solution. Many users may not 
even know that the menu exists inspite of the downward arrow.

Kind Regards,
Raj Sekharan
