@joe,@Iwe: See \’ref\’ in the Extjs docs (e.g. on the Panel class). It (ref) will create a reference to the object when instantiated.

I was looking for what Joe was looking for, but I see he wasn\’t answered. Can anyone tell us how to refer to an object that was created with xtype? I don\’t want to use \

I am writing an application which stores the Ext objects in a database I am retrieving the configuration from the server and rendering the objects. I want to manupulate the object configuration prior to adding them to the container. Is there a way of adding xtypes for things like?:

store: {
autoDestroy: true,
url: \\\’plants.xml\\\’,
reader: {
record: \\\’plant\\\’,
fields: [
{name: \\\'common\\\', type: \\\'string\\\'},
]
}),

I\\\’m string to lazy render all of the components. I\\\’ve tried :

Ext.reg(\\\’xmlreader\\\’,Ext.data.XmlReader);

store: {
autoDestroy: true,
url: \\\’plants.xml\\\’,
reader: {
xtype: \\\’xmlreader\\\’,
record: \\\’plant\\\’,
fields: [
{name: \\\'common\\\', type: \\\'string\\\'},
]
},

but to no avial… any thoughts?

The example line got broken of, I was just referencing the line from your post. Here is the rest of my comment:
[example line from above(xtype...)], how can I call i.e. getSelectionModel() on mygrid?

Very clear description, thanks.

As by the above example ({xtype:\’mygrid\

ad 2. Yes I was mistaken, I read pre ext3 where you write pre ext2.

ad 3. Ghe don\’t get me wrong. I love extjs as well, and bought recently a license because I want to use this library. I only wonder how extjs1 worked then. Since the only way of greedy instantiation I can think of is something like the following

p = new SubPanel();
w = new Widget().registerAOnClickFunction(function (e) {p.show()}}

this is a waste indeed.
But why not simply

w = new Widget().registerAOnClickFunction(function (e) {new Panel.show()}}

There is no need to instantiate Panel beforehand, in global scope.

ad 4. It was just an example, definitely not Extjs. $ is (DOM) getElementById, the example I provide here is maybe clearer. Still not extjs, but it illustrates the concept.
