Can you explain your question a bit more? I'm guessing your looking for something like this:

var tg = new Ext.ux.TreeGrid({
          //set config properties....
});

tg.on('columnresize', function(colIndex, newSize){
     //doSomething.....
}, this);

As of EXTJS 4, the columnresize event has different callbacks FYI:
