QML Animation

[narayanan.krish]

Hello all!
I am dynamically creating a page uisng createComponent. I like to implement any kind of animation while closing the page.
I am trying to implement the animation before destroying the page using PropertyAnimation on "opacity".
But it is now working.
Kindly help to fix it?

Thanks & Regards,
Narayanan

Hi,

You can start the animation when you want to destroy the page and then use "onStopped":http://qt-project.org/doc/qt-5.0/qtquick/qml-qtquick2-animation.html#onStopped-signal to actually destroy the page

Fo e.g,

@
import QtQuick 2.0

Rectangle {
id: root
width:1280
height:720
color: "grey"
PropertyAnimation { id: animation; target: root; property: "opacity";
duration: 1000; from: 1.0; to: 0.0;
easing.type: Easing.InOutQuad ;

    onStopped: Qt.quit()
}

MouseArea {
    anchors.fill: parent
    onClicked: {
         animation.start();
    }
}

}
@

Hope this helps...
