QVideoWidget::setFullScreen(true) is not working properly first time when added QVideoWidget in QStackedLayout

Hi,
Here is my code in which QVideoWidget::setFullScreen(true) is not showing videoWdiget in fullscreen when added in QStackedLayout:

QStackedLayout *stackedLayout = new QStackedLayout;
stackedLayout->addWidget(m_videoWidget);
stackedLayout->setCurrentIndex(0);

    QBoxLayout *mainLayout = new QVBoxLayout;
    mainLayout->addLayout(stackedLayout, 1);

    setLayout(mainLayout);

When video start playing, I am setting videoWdiget to fullscreen

void MediaPlayer::playbackStateChanged(QMediaPlayer::PlaybackState state)
{
//qDebug() << QString("MediaPlayer::playbackStateChanged state=%1").arg(state);
switch (state) {

case QMediaPlayer::PlayingState:
    m_videoWidget->setFullScreen(true);
    break;
}

}

although m_videoWidget->isFullScreen is true, but window is not fullscreen. When I clicked my 'FullScreen' button again, it will set to m_videoWidget->isFullScreen to false and when I press 'FullScreen' button again, then it will show videoWidget as fullScreen.

My observation is it required user interaction and then QVideoWidget::setFullScreen working fine. Any hint what is missing here?

================Previous code - which was working fine
Earlier I have this code in which videoWidget is displaying as fullScreen, but I have to use QStackedLayout so that I can switch between ImageViewer and QVideoWidget based on image/video media file type.

void MediaPlayer::setPlayerLayout_old()
{
try {
QBoxLayout *displayLayout = new QHBoxLayout;
displayLayout->addWidget(m_videoWidget, 1);

    QBoxLayout *mainLayout = new QVBoxLayout;
    mainLayout->addLayout(displayLayout, 1);

    setLayout(mainLayout);

    if (!isPlayerAvailable()) {
        QMessageBox::warning(this, tr("Service not available"),
                             tr("The QMediaPlayer object does not have a valid service.\n"\
                                "Please check the media service plugins are installed."));
    }
} catch (...) {
    qCritical() << "MediaPlayer::setPlayerLayout: Exception occured. ";
}

}

Thanks in advance for your help!

@SGaist Can you please add your comments regarding this issue?

Hi,

That's because it's in a layout inside another widget.

On a side note, please format your code properly using coding tags or the </> button in the editing toolbar.
