Just to be clear: The trouble is that your human-readable ComboBox values (displayField values) are simply unavailable until you load the store. When a record is loaded you obtain the...

Most components have methods like "setValue" or "setWidth" that allow you to change their behavior or appearance after they are instantiated. You should consult the documentation to see if the...

This may or not be what bruno~ is looking for, but this question, to me, is always about what seems to be an egregious oversight in the design of DateField: the need to specify which "page" (month)...

So that non-premium Ext users can get help with this topic, here's an example of adding a checkbox toggle to the 'itemclick' event of the TreePanel. That is, when the item text is clicked, the...

There used to be a legend, as I recall.

I believe the pink boxes with stars refer to singletons, the blue boxes to classes, the brown boxes to namespaces, and the gears to 'components.'

As an example, this brief extension should get you a right-aligned button:

When using Ext.define() to define an override, I get the expected result in at least one browser but a fatal error in others. Errors are read from either Firebug or the Chrome Developer console.

Thanks for the tip. Is it safe to say I should only be using Ext.override() or calling the override method on a class when I've defined that class myself (i.e. not on ExtJS built-ins)?

Just a couple suggestions until someone more knowledgeable shows up:

- Try wrapping your code in CODE and /CODE tags with [BRACES]; it will be easier to read and preserve whitespace
- Have you...

I don't have experience doing this inside a QuickTip pop-up, but I believe you can achieve the desired result wherever HTML is allowed by simply writing event handling into an anchor.

Example columns definition where a renderer is used to display a pretty date/time format (array of Column instances for a ColumnModel):

If you're using the data in a ColumnModel (for a Grid), then it is very easy to do this with a renderer function, which is a config property of Column instances (and your ColumnModel accepts an array...

If I understand correctly, I think you are interested in populating a DateField (Calendar picker) with only a few available dates. This is the problem of needing an "inverse" of the disabledDates...

You can't add listeners to the initComponent() method of an extension, because by the time the initComponent() method is called, event-handling behavior has already been determined. To add listeners...
