How can I remove borders from a Windows QML application

Question

This is similar to question 4799748, but I'd like to remove Windows borders from a QML application, so it starts up without minimise/maximise/close etc.

I guess I need to set the Window flags to Qt.CustomizeWindowHint, but I'm new to QML and can't see how to do that. The editor auto-completes the Qt.CustomizeWindowHint text, but I can't see how to apply that to the top level window.

Answer 1

You need to set the Qt::FramelessWindowHint window flag. Since QDeclarativeView doesn't have a constructor accepting window flags you will have to set them after creating the view:

QDeclarativeView *viewer = new QDeclarativeView(0);
viewer->setWindowFlags(Qt::FramelessWindowHint);
viewer->setSource(QUrl::fromLocalFile("main.qml"));
viewer->show();

BTW, if you are using qmlviewer, you can pass -frameless to remove the border from its window.

Answer 2

Marko Frelih,

It's easy, just put flags: Qt.FramelessWindowHint inside your ApplicationWindow QML code

Answer 3

Use flags: Qt.WindowFullScreen it works .

Other options:

flags : Qt::WindowFlags
