use value from dynamically created widget in a slot

[giblit]

because you need to put void before MainWindow more than likely.
like this:

void MainWindow::somethingSlotIForgotName(){
//do something
}

void MainWindow::somethingSlotIForgotName(){
//do something
}

To copy to clipboard, switch view to plain text mode 

Edit:: if it is a private/slot you have to declare it as void/unsigned/int/ect
if it is the public function (the main one for the class) you do not have to declare it.
