Exit video full-screen

[HW-Developer]

@mrjj this is how it shows :

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

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();
  player->play();

@mrjj It's not working, when i make the changes, i run the app and click fullscreen button, it crash, and it blocks the app

[HW-Developer]

@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

@HW-Developer

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