Question

I am using a QStackedWidget on my mainWindow. The firstPageWidget on stackedWidget contains 3 buttons. Now If I will press the first button on firstPage, I want the stackedWidget show the 2nd Page widget. Following are the details

I tried to connect like this in my mainwindow

connect(firstPageWidget->button1,SIGNAL(clicked()),stackWidget,SLOT(setCurrentIndex(int)));

Now I want to know how to pass the value of index number to stackWidget to set currentIndex?

If my question is not much clear please tell me I will explain more.

You probably need to use QSignalMapper class:

QSignalMapper mapper = new QSignalMapper(); // don't forget to set the proper parent
mapper->setMapping(firstPageWidget->button1, 2); // 2 can be replaced with any int value
connect(firstPageWidget->button1, SIGNAL(clicked()), mapper, SLOT(map()));
connect(mapper, SIGNAL(mapped(int)), stackWidget, SLOT(setCurrentIndex(int)));
