How to add sparkline to ListGrid

[abthere]

I'm trying to add jquery sparkline to a listgrid. The challenge is that sparkline function must be called when new data is rendered. There's seem to be an elegant solution in smartclient world as outlined here http://forums.smartclient.com/showthread.php?p=17032 but how can I observe grid.body redraw event in SmartGWT world? Overriding ListGrid.redraw() doesn't work.

it works!

Turns out that solution can be the same. Just add a native function to your grid class:

public native void addSparklines()/*-{
	    var self = this.@com.smartgwt.client.widgets.BaseWidget::getOrCreateJsObj()();
	    var body = self.body;
	    if (body == null) return;
	    self.observe(body, "redraw", "jQuery('.sparklines').sparkline('html',{ type:'bar', barColor:'green' });");
	    body.redraw();
	}-*/;

and call it onDraw:

grid.addDrawHandler(new DrawHandler() {
			@Override
			public void onDraw(DrawEvent event) {
				grid.addSparklines();
			}
		});
