[Qt-qml] why does signal clicked (MouseEvent mouse) not parse

[Bartosh Wroblevksy]

Thanks, but I was hoping I can do something like this:
//Example Button ComponentItem {id: rootElementsignal clicked(MouseEvent mouse)...MouseArea {anchors.fill: parentonClicked: {rootElement.clicked( mouse );}}}
Thanks,Bartosh

> Hi Bartosh,
> Mouse events in QML should be handled using a MouseArea component, and then the signal should be passed to the parent component when necessary. I am assuming you are creating a custom UI component that needs to have a clicked signal, so here would be a typical example:

> //Example Button Component
> Item {
>     id: rootElement
>     signal clicked
>     
>     ...
>     
>     MouseArea {
>         anchors.fill: parent
>         onClicked: {
>        	    rootElement.clicked();
>         }
>     }
> }

> Define the signal on the root element of the component and create a MouseArea where you want the clickable area, in this example I have ensured that it fills the boundaries of the control with anchors.fill. When the clicked event is detected on this MouseArea, it calls the clicked signal on the root element, and this can be handled in your application view in exactly the same way as shown in the MouseArea here.
