Open new fullscreen qml window and close/hide current fullscreen window

RiteshPanchal

I am using qt 5.2.1 on nvidia TX1 running Ubuntu 14.04.
I want open new fullscreen Windows without boarders from currently running fullscreen qml.

I have 2 qml files

startup.qml
Preview.qml

On startup, startup.qml is loaded
main.cpp

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    engine.load(QUrl(QStringLiteral("qrc:///qml/qml/startup.qml")));

    return app.exec();
}

startup.qml

import QtQuick 2.2
import QtQuick.Window 2.0
import QtQuick.Controls 1.1

ApplicationWindow {
    id: rootWindow
    width: Screen.width
    height: Screen.height
    visible: true
    visibility: Window.FullScreen

    Item {
        focus: true

        Timer {
            interval: 2500
            running: true;
            onTriggered: {
                var component = Qt.createComponent("qrc:///qml/qml/Preview.qml")
                var window    = component.createObject(rootWindow)
                rootWindow.visible = false
                window.show()
            }
        }
    }
}

Preview.qml

import QtQuick 2.0
import QtQuick.Window 2.0
import QtQuick.Controls 1.1

ApplicationWindow {
    id: rootWindow
    width: Screen.width
    height: Screen.height
    visible: true
    visibility: Window.FullScreen

}

After timer delay startup.qml is getting closed and new Preview.qml window appears. But the problem is that it appears in window with boarder and ubuntu unity side pane.

So how can i open second windows also in fullscreen mode?

Hello, you need to set window flag to avoid drawing borders.

flags: Qt.Window | Qt.FramelessWindowHint

Thanks for the Reply.
I will try your solution also.
But i found one solution.

I just replaced

window.show()

in startup.qml to

window.showFullScreen()

And this fulfills my requirements.
