Fullscreen widget

Question

How can I make my widget fullscreen? I\'ve tried something like this:

void MainWindow::SetFullScreen()
{
    // Make our window without panels
    this->s         


        

Answer 1

This code will allow you to set a full screen by double clicking and to return back to the normal view by double clicking again.

void myWidget::mouseDoubleClickEvent(QMouseEvent *e) {
  QWidget::mouseDoubleClickEvent(e);
  if(isFullScreen()) {
     this->setWindowState(Qt::WindowMaximized);
  } else {
     this->setWindowState(Qt::WindowFullScreen);
  }
}
