Use QML ToolTip with Label

问题:

I'm using a ToolTip with a TextField. This works properly.

RowLayout {
    property string toolTipText

    TextField {
        hoverEnabled: true
        ToolTip.visible: tooltipText ? hovered : false
        ToolTip.text: tooltipText 
    }
}

But with a Label it wont work properly. hoverEnabled is not available in the Label Component. So i've tried it with a MouseArea

RowLayout {
    property string toolTipText

    Label {
        MouseArea { 
            anchors.fill: parent
            hoverEnabled: true
            ToolTip.visible: tooltipText ? hovered : false
            ToolTip.text: tooltipText 
        }
    }
}

The ToolTip will be shown, but not when mouseover the Label. It actually shows when entering the Window.

Is there any solution for this?

MouseArea does not have the ToolTip but the Label, so that you must move it and activate it using the containsMouse property of MouseArea:

RowLayout {

    Label {
        text: "label"
        property string toolTipText: "message"
        ToolTip.text: toolTipText
        ToolTip.visible: toolTipText ? ma.containsMouse : false
        MouseArea {
            id: ma
            anchors.fill: parent
            hoverEnabled: true
        }
    }
}
