The widget query setup enables two things: 1. You can then easily retrieve a widget that lives in the browser in the command line, like I do all the time with firebug. Then you get a kind of a REPL work flow. 2. It enables an abstraction of the observer pattern. At the moment there is still a direct relation between the event publisher and the event handler. I can say many bad things of ExtjJs, but there event handling is very powerful. They have a so called event bus. The event bus handles all event publishers and handlers. So, in a controller, I can say, listen to any combox dropdown event and act upon it, without having any direct reference to all the comboxes. See this reference <http://docs.sencha.com/extjs/5.1/5.1.0-apidocs/#!/api/Ext.app.EventDomain> . Building on that last bit, I could even take this further and I have a central event declaration file in which I can declare exactly which classes/widgets listen to what classes/widgets. And thats quite powerful. -- View this message in context: http://qooxdoo.678.n2.nabble.com/Quickly-reference-widgets-in-browser-and-code-tp7586543p7586557.html Sent from the qooxdoo mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Dive into the World of Parallel Programming!
