[Qt-qml] QML Action element

[warwick.allison at nokia.com]

Certainly a ui-style-specific module could make an "Action" element like this (just as qt-components has apparently), if it made sense for the types of interactions in that style. No extra functionality is needed in QML to enable such an element.

If we are to have truly revolutionary user experiences, we need to get out of the habit of first building a big dull traditional framework and then hoping that something pleasant can be shoehorned out of the constraints implied by that framework. This is the Big Lesson of QML over Qt.

Thanks Joona,
the initial push came from qt-components/Meego:
http://qt.gitorious.org/qt-components/qt-components/trees/master/src/MeeGo
which has own Action.qml implementation for the UI. Just wondering, does the Symbian side need one as well?

The action could live in the declaration pretty nicely:
Item {
    id: parent

    Action {
        id: actionOwnedByParent
        text: "jeah!"
        icon: "icon1.jpg"

        onTriggered: {
            ...
        }
    }

    Menu ...
    Button ...
    Toolbar...
}

Although, I don't know if we want to promote action based menus/toolbars anymore.

Hi,

QtDeclarative library registers QAction so that you can access QAction-based properties from QML. For example WebView element has back, forward, stop, reload actions for controlling the web page being shown. There is no Action element though for creating new actions from QML and I am not aware of any plans of chaning this, i.e. you cannot really write "property variant myAction: Action {}". What is the use case you want to solve with the Action element? QAction has roots in QWidget/QGraphicsWidget world, there may be another solution to your problem that fits better with the QML principles and declarative way of building user interfaces.

Hi,
I remember some rumors that QtQuick would implement QML Action element (equals QAction) as built in type. What is the current status?

Thanks,
