eventHandling : mouse Coods

Hey,

In javascript I used to do :

myCanvas.addEventListener('mousemove', mouseCheck, false);

function mouseCheck(e){
    var x, y;
    x = e.pageX;
    y = e.pageY;
    //something...
}
and this way I had the coods of the mouse in my function.

How can I do this in Amber ?

I may use TagBrush>>onMouseMove: but how can I get the mouse coods ?

Thanks,

I don't know if it is not safer (from cross-browser PoV), since jQuery is included with amber, to rather reuse jQuery bind to hook an event.

TagBrush should have asJQuery which could be used for this, if I am not mistaken.

    Hi!

    You can do: (I didn't test it)

    myCanvas addEventListener: 'mousemove' do: [:e |
    | x y |
    x = e pageX.
    y = e pageY.
    "Something"
    ]

    If you want to extract the callback, then I would do something like:

    myCanvas addEventListener: 'mousemove' do: [ :e | self mouseCheck: e ]

    mouseMove: anEvent
    | x y |
    x = anEvent pageX.
    y = anEvent pageY.
    "Something"
