Add button to QVideoWidget - c++

Question

everyone! I try to set a click property to a QMediaPlayer Element, but I can not find the mode to make it, and if I try to put a button in front to Video, the button puts behind to video, even with
button->raise();
videoWidget->lower();
And If I put a Button to fullscreen the screen turns in black and don't shows the video
this id the code of the video player
QMediaPlayer *player = new QMediaPlayer(this);
QVideoWidget *vw = new QVideoWidget(this);
QMediaPlaylist *PlayList = new QMediaPlaylist(this);
PlayList->addMedia(QUrl::fromLocalFile("/home/user/Videos/video.mp4"));
PlayList->setPlaybackMode(QMediaPlaylist::Loop);
QVBoxLayout *layout = new QVBoxLayout;
layout->addWidget(vw);
player->setVideoOutput(vw);
player->setPlaylist(PlayList);
vw->setGeometry(0,0,800,480);
vw->show();
player->play();

One possible solution is to create a widget where the QVideoWidget is placed through a layout, the button is also added and we change the position through the resizeEvent() event.
#include <QApplication>
#include <QMediaPlayer>
#include <QMediaPlaylist>
#include <QPushButton>
#include <QUrl>
#include <QVBoxLayout>
#include <QVideoWidget>
#include <QDebug>
class VideoWidgetButton: public QWidget{
QPushButton *btn;
QVideoWidget *vw;
QMediaPlayer *player;
public:
VideoWidgetButton(QWidget *parent=Q_NULLPTR):QWidget(parent){
setLayout(new QVBoxLayout);
layout()->setContentsMargins(0, 0, 0, 0);
vw = new QVideoWidget(this);
btn = new QPushButton(this);
btn->setIcon(QIcon(":/icons/tux.jpeg"));
btn->resize(QSize(128, 128));
btn->setIconSize(QSize(128, 128));
connect(btn, &QPushButton::clicked, [](){
qDebug()<<"clicked";
});
layout()->addWidget(vw);
player = new QMediaPlayer(this);
player->setVideoOutput(vw);
QMediaPlaylist *playList = new QMediaPlaylist(this);
playList->addMedia(QUrl("qrc:/video/SampleVideo_1280x720_1mb.mp4"));
playList->setPlaybackMode(QMediaPlaylist::Loop);
player->setPlaylist(playList);
player->play();
}
protected:
void resizeEvent(QResizeEvent *ev){
btn->move(rect().bottomRight()-btn->rect().bottomRight());
return QWidget::resizeEvent(ev);
}
};
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
VideoWidgetButton w;
w.resize(640, 480);
w.show();
return a.exec();
}
