Displaying 1 widget at time

[afflictedd2]

Hi everyone,

I'm building a gui that creates a mainwindow in which there are two toolbar icons, when you click on any of them a certain dialog should appear. I have done this but it is crashing because it's not closing one widget when the other one opens. I was wondering if there is a command that will clear the CentralWidget, so that the new dialog may open without crashing. Here's my code:

void MainWindow::dialog1()
{
    if (!dialog) {
        dialog = new Dialog1;
    }
    this->setCentralWidget( dialog );
    dialog->show();
}
 
 
void MainWindow::dialog2()
{    
    if (!dialog2) {
        dialog2 = new Dialog2;
    }
    this->setCentralWidget( dialog2 );
    dialog2->show();
}

void MainWindow::dialog1()
{
    if (!dialog) {
        dialog = new Dialog1;
    }
    this->setCentralWidget( dialog );
    dialog->show();
}


void MainWindow::dialog2()
{    
    if (!dialog2) {
        dialog2 = new Dialog2;
    }
    this->setCentralWidget( dialog2 );
    dialog2->show();
}

To copy to clipboard, switch view to plain text mode

try using a QStackedWidget for that.

I don't like the arrows in QStackedWidgets though, are these removable?

They are only visible in Designer so that you can switch pages easily when designing them. When you build your application, they will go away.
