    well for ESC, you would override KeyPressEvent for mVideoWidget
    and respond to it. same with click.
    What type is mVideoWidget ?
    Its it your own child class or just plain Qt one?

      Hi
      You could subclass the QVideoWidget and use your own class instead
      where you react to key and mouse.
      Alternatively there is also event filters
      http://doc.qt.io/qt-5/eventsandfilters.html
      that allow you to do this without subclassing.

      Sample of subclassing and reacting to key / mouse

      #include <QKeyEvent>
      #include <QVideoWidget>
      
      class MyVideoWidget : public QVideoWidget {
       public:
        MyVideoWidget(QWidget* parent = nullptr) : QVideoWidget(parent) { }
       protected:
        virtual void mouseDoubleClickEvent(QMouseEvent* event) override {
          showNormal();
        }
        virtual void keyPressEvent(QKeyEvent* event) override {
          if ( event->key() == Qt::Key_Escape) {
            showNormal();
          }
        }
      };

        @mrjj Thank you so much it works, the only problem left is that the video detach from the MainWindow.
        Do you know why?

          Hi
          On some platforms ( Windows) the video is actual an overlay and not really inside the window.
          Im not sure if that is what you are seeing ?
          When you say detach from mainwindow, does it show as its own window or how does it look?
          Im asking as if you dont give a QWidget ( including QVideoWidget) a parent, it will become a window on its own.
          (if you show the code where u create the QVideoWidget, its easy to spot if that is the issue)
          Basically the difference is like
          QVideoWidget *vid= new QVideoWidget;
          versus
          QVideoWidget *vid= new QVideoWidget(this); <<< "this" is the parent

              Super, i really think its just because your are not assigning a parent when you create it.
              it then becomes a window.
              So instead of replacing the other QVideoWidget you have, it just opens a (new) window.
              Thats easy fixed by assigning a parent.
              Did you based this off some sample i can look at ?

                @mrjj I make you a simple example, it shows the same issue:

                #include "MyPlayer.h"
                
                MyPlayer::MyPlayer(QWidget *parent)
                	: QMainWindow(parent)
                {
                	ui.setupUi(this);
                	QWidget *zoneCentrale = new QWidget;
                	setCentralWidget(zoneCentrale);
                	player = new QMediaPlayer(this);
                	videoWidget = new MyVideoWidget(this);
                	videoWidget->setGeometry(100, 100, 500, 400);
                	fullScreen = new QPushButton("full-screen", this);
                	layout = new QVBoxLayout();
                	
                	
                	player->setMedia(QUrl::fromLocalFile("C:/Users/ouafa/Downloads/nature.mp4"));
                	player->setVideoOutput(videoWidget);
                	layout->addWidget(videoWidget);
                	layout->addWidget(fullScreen);
                	
                	zoneCentrale->setLayout(layout);
                	player->setVolume(100);
                	setCentralWidget(zoneCentrale);
                	
                	QObject::connect(fullScreen, SIGNAL(clicked()), this, SLOT(on_bt_agrandi_clicked()));
                
                	videoWidget->show();
                	player->play();
                	qDebug()<< player->isVideoAvailable();
                	qDebug() << player->availableMetaData() << player->currentMedia().canonicalUrl();
                }
                void MyPlayer::on_bt_agrandi_clicked() {
                	if (!videoWidget->isFullScreen()) {
                		videoWidget->setFullScreen(true);
                	}
                	
                	qDebug() << "hi there!";
                }

                  Hi
                  I could not reproduce
                  alt text

                  However, using you code 100% as is - made app crash. Not sure why.
                  (just tried again to be sure)

                  This is the code i used. i rearranged it a bit and gave zoneCentrale directly to the layout.
                  else its pretty much the same. Can you try this ? ( change the mp4 file ofc)

                   QWidget* zoneCentrale = new QWidget;
                    setCentralWidget(zoneCentrale);
                    auto player = new QMediaPlayer(this);
                    auto videoWidget = new QVideoWidget(this);
                    player->setVideoOutput(videoWidget);
                  
                    auto fullScreen = new QPushButton("full-screen", this);
                    auto layout = new QVBoxLayout(zoneCentrale);
                  
                    player->setMedia(QUrl::fromLocalFile("F:/Dropbox/_qtprojects/wontdelete/test2.mp4"));
                  
                    layout->addWidget(videoWidget);
                    layout->addWidget(fullScreen);
                  
                    player->setVolume(100);
                  
                    QObject::connect(fullScreen, SIGNAL(clicked()), this, SLOT(on_bt_agrandi_clicked()));
                  
                    videoWidget->show();

                      @mrjj It's working after i verify everything, it is the escape key event, it should be setFullScreen(False) instead of showNormal();

                      I really thank you for your help. It was really nice
                      Good luck and have a good days

                                Hi
                                Welcome back.
                                So what happens when you call showNormal(); ?
