Within the checkbox listener you can put code to find the children and check them also: The tree has to bexpanded before adding the other checkmarks because the children nodes are not created till the parent is expanded the first time.

    dojo.connect(cb, "onChange", function() {
    var treeNode = dijit.getEnclosingWidget(this.domNode.parentNode);
    //treeNode.expand();
    treeNode.tree._expandNode(treeNode);
    dojo.publish("/checkbox/clicked", [{
      "checkbox": this,
      "item": treeNode
    }]);

    var parentcb = this;
    console.log(parentcb.checked)
      treeNode.getChildren().forEach(function(item) {
      var checkbox =  dijit.getEnclosingWidget(item.labelNode.children[0]);
     checkbox.set('checked', parentcb.checked)
  });
  });
