Call a function by onClicked in qml

[A Former User]

I am trying to call a function clearcanvas by "onClicked" event of the button.
Can anybody help me out on this so that when I click on the button it should call the function and execute it.

1 : Declare the function clear outside of the Canvas component
2 : Declare the var ctx as a property of canvas
3: please post your codes by text rather than image next time, this would easier for us to help you

@
QtObject{
id: param

function clearCanvas(ctx){
ctx.clearRect(....)
}
}

Canvas{
id:canvas

property var ctx

}

//.....
Rectangle{
//.....
MouseArea:{
anchors.fill:parent

onClicked:{
clearCanvas(canvas.ctx)
}
}
}
