Modify Width/Height in window component

Hello,
I heve the following window:

		view : "window",
		head : {
			view : "toolbar",
			type : "SubBar",
			elements : [{}, {
				view : 'label',
				label : "APP_NAME",
				align : "center"
			}, {
				view : "button",
				label : "Close",
				click : "close_modal",
				align : "right"
			}]
		},
		top : positionY,
		left : positionX,
		body : {
			view : "list",
			id : "ewmon_window_format_election",
			data : addresses,
			datatype : "json",
			template : "#name#", 
			select : true,
			type : {
				width : 300
			}
		},
		height : 300,
		width : 300,
		move : true,
		id : 'ewmon_window_show_election'
	}).show();

How can I modify the dimension. For the component window there is no setWidth/Height method?

Thanks for your help
Danilo

$$('ewmon_window_show_election').define("width", 1000); $$('ewmon_window_show_election').refresh();
