[Solved] How to scroll flickable smooth from code

[Per-Erik Kristensson]

I working in QtQuick 1.1 and I have a textbox with a lot of text inside a flickable. I also have a button. When I press the button I want to scroll the content. I have solved that by changing contentY position in the flickable. That works but is a bit "chunky". Is there some easy way to do this smoother?

My experimental code:

@
import QtQuick 1.1

Rectangle {
id: rectangle2
width: 360
height: 160

MouseArea {
    x: 102
    width: 60
    height: 50
    anchors.left: parent.left
    anchors.leftMargin: 236
    anchors.top: parent.top
    anchors.topMargin: 44
    onClicked:
    {
        flickable1.contentY += flickable1.height * 0.8;

        if(flickable1.contentY > flickable1.contentHeight - flickable1.height )
            flickable1.contentY = flickable1.contentHeight - flickable1.height;
    }

    Rectangle {
        id: rectangle1
        color: "#d30303"
        anchors.fill: parent

        Text {
            id: text1
            color: "#ffffff"
            text: qsTr("Scroll")
            anchors.horizontalCenter: parent.horizontalCenter
            anchors.verticalCenter: parent.verticalCenter
            verticalAlignment: Text.AlignVCenter
            horizontalAlignment: Text.AlignHCenter
            font.pixelSize: 12
        }
    }
}

Flickable {
    id: flickable1
    x: 0
    y: 0
    width: 123
    height: 136
    flickableDirection: Flickable.VerticalFlick
    clip: true
    contentWidth: text2.width
    contentHeight: text2.height


    Text {
        id: text2
        text: qsTr("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla eu mauris a quam rhoncus tincidunt sed sed massa. Fusce tristique gravida justo mattis accumsan. Mauris ultrices ante ante. Sed venenatis feugiat velit ut commodo. Duis iaculis aliquam nibh vitae mollis. Donec tempus odio quis orci pulvinar accumsan.

Duis elit ante, imperdiet lobortis vulputate nec, iaculis vel nunc. Suspendisse potenti. Sed pharetra odio ut mauris iaculis eleifend")
        anchors.fill: parent
        width: 123
        height: 500

        wrapMode: Text.WordWrap
        font.pixelSize: 12
    }
}

}

Hello

if you say smoother you mean with a transition? So simply use a transition to change the y position of the content.

You are right. I solved it by using a PropertyAnimation. A bit clumsy, but it works and is good enough for me :-)
