Reopen the MainWindow

[thibs]

Hi guys! I was trying to show mainwindow after to hide that, but I couldn`t do that.

First I hide the mainwindow in the pushbutton action and open a dialog window:

void MainWindow::on_NewTest_clicked()
{
    this->hide();
    NewTest newtest;
    newtest.setModal(true);
    newtest.exec();
 
}

void MainWindow::on_NewTest_clicked()
{
    this->hide();
    NewTest newtest;
    newtest.setModal(true);
    newtest.exec();

}

To copy to clipboard, switch view to plain text mode 

Then in this dialog window I would like to add a button to return to the mainwindow, but I searched and I didn`t found anything about it. Thanks guys!

To show a window simply call show() on it.

I tried that but it didn`t work. Just show a window for half of a second and then close it. I tried to call MainWindow using this code:

void NewTest::on_Home_clicked()
{
    MainWindow w;
    w.show();
 
}

void NewTest::on_Home_clicked()
{
    MainWindow w;
    w.show();
  
}

The object goes out of scope when the function ends.

So, how do I do that? I know how to open and close QDialog, but in the QDialog I would like to have a button that close the QDialog and reopen the QMainWindow

Do you understand what is the meaning of the above sentence ?

reopen the QMainWindow

Your code doesn't re-open anything. It creates a new window and shows it. And then it gets deleted.

I understand, I just wanted to show what I was trying to do. Do you guys know how do I show the MainWindow inside a pushbutton event in another class after it be hidden

Do you want to show the window again without closing the dialog?
