Call widgets show slot.
mainwindow->show();

I believe the default atribute of QMainWindow is set with Qt::WA_DeleteOnClose that means when you close your mainwindow it also gets deleted and theres no way to just show it again. WidgetAttributes

In your case, the easiest way is to simply call QWidget::hide() and QWidget::show()

Try with simple example like this.

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();

QPushButton b1("Close");
QPushButton b2("Show");

QObject::connect(&b1,SIGNAL(clicked()),&w,SLOT(close()));
QObject::connect(&b2,SIGNAL(clicked()),&w,SLOT(show()));


b1.show();
b2.show();
return a.exec();

}
