add DropDownButton.setDropDown() method

[guest]

Tested in version 1.0.1. This bug is reproducable.

Given:

var toolbar   = new dijit.Toolbar();
var button    = new dijit.form.DropDownButton({ label: 'Button Label' });
var menu      = new dijit.Menu();
var menuitem  = new dijit.MenuItem({ label: 'Menu Item' });

It should be possible to create an desktop-application-like menubar like so:

toolbar.addChild( button );
button.addChild( menu );
menu.addChild( menuitem );

But this does not work.

Instead of calling button.addChild(), you must directly set button's .dropDown property like so:

button.dropDown = menu;

This appears to be a defect.

If DropDownButton.addChild() is inappropriate for this action, perhaps DropDownButton.addDropDown() would be correct.

No, it's working as designed. addChild() is more for the case where you can have any number of children (including zero)... not this case where there is a one-to-one mapping.

bill:

even if addChild is designed to do something different, there should be an addPopup or setDropDown() method on the dropDownButton.

OK, not sure what the advantage of a method would be beyond setting that property directly. Perhaps there's some additional book keeping it needs to do.
