Unsolved unable to maximize QfileDialog in stackwidget

[guru007]

I try to open a video file with QfileDialog but that dialog pop out with small dimensions in centre of its parent widget.How I can open file dialog maximized as default.
Here is some code:
player::player(QWidget parent) :
QWidget(parent),
ui(new Ui::player)
{
QFont player_font;
ui->setupUi(this);
QDesktopWidget screen;
video_dialog = new QFileDialog(this);
video_dialog->setModal(true);
}
void player::on_toolButton_6_clicked()
{
video_dialog->setSizePolicy(QSizePolicy::MinimumExpanding,QSizePolicy::MinimumExpanding);
QString video_location;
video_location = video_dialog->getOpenFileName(this,tr("Open File"),"/home/apaul/Videos", tr("Video-Files ()"),0);
player1->setMedia(QUrl::fromLocalFile(video_location));
player1->play();
}
if I use :
video_dialog->showMaximized();
then it popped up as maximized but how can I get selected filename from that.

Hi,
May be getOpenFileName help you?

@guru007
Hello,
QWidget::setWindowState and QDialog::setModal might be of use.

Hi and welcome to devnet,

getOpenFileNames is a static method that uses the native file dialog. So the parameters you are modifying have not incident when allying getOpenFileNames.

selectedFiles will return what you have selected.

Hope it helps

Set the Qt::FramelessWindowHint on your dialog
