[Qt-qml] QML Questions

[kai.koehne at nokia.com]

Hi Jason,

the docs I get when downloading the latest snapshot are correct :) I'm suspecting that the qml help you have is from an outdated version of creator / qt. This can happen because all help files from unreleased versions of Qt share the same 'namespace', and therefore QtCreator has a hard time to decide when it needs to update the help collection and when not ...

What you could try is explicitly re-registering the new one:

 * in QtCreator, go to Tools, Options ..., Help, Documentation
 * Remove 'com.trolltech.qml.460'
 * Add qml.qch from $CREATORDIR\share\doc\qtcreator

Hope this helps,

Kai

Thanks, I got something better, but still does not work.
ListView{
        width: 1000
        height: 700
        anchors.fill: parent
        model: visualModel
        highlightFollowsCurrentItem: true
        spacing: 10
            NumberAnimation    on visibleArea.yPosition {
                from:0.0
                to: 1.0
                easing: Easing.Linear
                duration: 10000
            }
    }

The message I get is yPosition is readOnly. But it is not marked as such in the

docs, and I think it would be super cool to have it as read-write so you can
auto scroll this stuff.

Is there a way to make my original list (with your corrections) just scroll like
credits at the end of a movie?

Oh, and I just installed http://get.qt.nokia.com/qtcreator/snapshots/latest/
(July 9 Windows) and it still has the "wrap: bool" documentation.

Thanks again!

It sounds like you've got out-of-date docs. Are you building yourself, or using
the beta2 release? As far as I can tell the docs are correct at HEAD.

You probably want to use the "on" syntax -- see
http://doc.qt.nokia.com/4.7-snapshot/qdeclarativeanimation.html#basic-property-animation.

If you truly do want a standalone animation object, you will need to also
specify a "target"
(http://doc.qt.nokia.com/4.7-snapshot/qml-propertyanimation.html#target-prop)

Michael
