Rectangle radius property not working with RadialGradient

[AliReza Beytari]

Hey guys!
This is my code:

import QtQuick 2.4
import QtQuick.Controls 1.2
import QtGraphicalEffects 1.0

ApplicationWindow {
    title: "Upload Form"
    width: 800
    height: 650

    RadialGradient {
        anchors.fill: parent
        gradient: Gradient {
            GradientStop { position: 0.0; color: "#ebebec" }
            GradientStop { position: 0.5; color: "#b4b4b4" }
        }
        opacity: 0.5
    }

    Rectangle {
        id: uploadForm
        width: 310
        height: 280
        anchors.centerIn: parent
        antialiasing: true
		
		radius: 10 // not working !!

        RadialGradient {
            anchors.fill: parent
            gradient: Gradient {
                GradientStop { position: 0.0; color: "#373a3d" }
                GradientStop { position: 0.5; color: "#313437" }
            }
            verticalOffset: -155
            angle: 90
        }
    }
}

But radius property of Rectangle not working when I use RadialGradient!!
How to fix this bug?!

Hi!
The following works:

import QtQuick 2.4
import QtQuick.Controls 1.2
import QtGraphicalEffects 1.0

ApplicationWindow {
    title: "Upload Form"
    width: 800
    height: 650
    visible: true


    Item {
        id: myFunkyRectangle

        width: 300
        height: 300

        RadialGradient {
            id: gradient
            anchors.fill: parent
            gradient: Gradient {
                GradientStop { position: 0.0; color: "white" }
                GradientStop { position: 0.5; color: "black" }
            }
            visible: false
        }

        Rectangle {
            id: mask
            anchors { fill: parent; margins: 18 }
            color: "black"
            radius: 30
            clip: true
            visible: false
        }

        OpacityMask {
            anchors.fill: mask
            source: gradient
            maskSource: mask
        }
    }
}
