MouseArea for QDeclarativeItem subclass

[tuxier]

Hi,
i have a custom type, QDeclarativeItem subclass called polygon.
I override shape, boundingRect and paint functions in it.
I can see the polygons that i describe in the below QML code:

import MyTypes 1.0
import QtQuick 1.0
import Qt 4.7

Item {
    id: container
    width: 350; height: 250

     Polygon {
         id: aPolygon
         x:0;y:0
         width: 20; height: 20
         name: "A simple polygon"
         color: "blue"
         vertices:[

         Point{x:20.0; y:40.0},
         Point{x:40.0; y:40.0},
         Point{x:40.0; y:20.0},
         Point{x:20.0; y:20.0}
         ]

         MouseArea{
             anchors.fill: parent
             drag.target: aPolygon
             drag.axis: Drag.XandYAxis
             drag.minimumX: 0
             drag.maximumX: container.width - parent.width
             drag.minimumY: 0
             drag.maximumY: container.height - parent.width
             onPressed:console.log("==============   ==onPressed")

         }


     }

     Polygon {
         id: bPolygon
         x:60;y:60
         width: 20; height: 20
         name: "A simple polygon"
         color: "blue"
         vertices:[

         Point{x:60.0; y:80.0},
         Point{x:80.0; y:80.0},
         Point{x:80.0; y:60.0},
         Point{x:60.0; y:60.0}
         ]

         MouseArea{
             //hoverEnabled: false
             enabled: visible
             hoverEnabled: visible
             anchors.fill: parent
             acceptedButtons: Qt.LeftButton | Qt.RightButton
             onEntered: {
                 console.log("==============   ==onEntered")

             }
         }


     }
}

The problem is that MouseArea cares the x, y, width and height properties of my polygon items, not the shape of my polygons.

For example for first polygon onPressed work for the rectangle x:0;y:0;width:20;height:20

How can i make MouseArea work for the polygon that vertices define.

I have overrided shape function, what should i do else?

Thanks

Hi,
I think you can give some "borders" to your "squared" MouseArea in this way:
Since poligon area is smaller than the MouseArea area, you can use in OnPressed slot you use Item::mapToItem to check if the click happened on the poligon or not,
So, if you click outside the poligon, mouseArea::mapToItem(pos, poligonObj) will return an invalid position value.
This trick could permit you can to discard these events and process only the valid ones.
