fullscreen button for particular widget

[abhay]

Hello!! I am trying to create a media player using Qt.I want to place a button for fullscreen mode.When I use the below code fullscreen works perfectly.

QWidget::showMaximized();

But I want to show only video widget like in the case of Vlc player.When I change my code to

ui->video->showMaximized();

the above code no error occurs but its not working at all(assuming I have a widget named 'video').So,how can I create a pushbutton for maximizing a particular widget only.(In my case video widget)?Thanks!

Hi,

Any chance that ui-video is inside a layout ?

You can only make windows fullscreen, so you need to first make your widget a window:

ui->video->setWindowFlags(Qt::Window);
ui->video->showMaximized();

and to go back make it a widget again:

ui->video->setWindowFlags(Qt::Widget);
ui->video->show();

@SGaist yeah it's inside a horizontal layout.
