For future reference, this approach only works if you know in advance all the roles you will use. You can use KSelectionProxyModel instead if you need a proper general implementation

Thank you @mrjj I will go ahead and mark this as solved then. I know my IP Editor isn't exactly elegant, but with the requirements I'm given and the restrictions, I've done the best I can.

You could use a QRubberBand to setup the line and once you release it add the QGraphicsLineItem to your scene.

Hi look at this sample http://www.java2s.com/Code/Cpp/Qt/Calculatorwithpushbuttons.htm Shows how to hook up buttons etc. (its numeric keypad) you can change it to use QApplication::focusWidget () const to input to whatever LineEdit that is selected.

@Jeroen3 Thanks for the reply. I tried using setCurrentIndex which helped me out . ui->tabWidget->setCurrentWidget(ui->tab);

@joeQ Thanks man.

AFAIK, you can't, however you can still re-use it by using something like: QString styleSheet("%1:checked {background-color: lightgreen; border: 1px solid;} " "%1 {background-color: red; border: 1px solid; padding: 6px}"); myWidget->setStyleSheet(styleSheet.arg(myWidget->metaObject()->className()));
