View Full Version : Ext.tree.TreePanel

17 Feb 2011, 4:47 AM
Hi all,

I'm currently evaluating upgrading our Ext3 app to Ext4.. creating simple versions of each component just to check them out.

I must be missing something here, but Ext.tree.TreePanel seems to be undefined? It's in the APIs but I can't seem to instantiate it...

Is it contained within another lib now?

Cheers for any help,

Seems that it's not included in ext-all-debug.js, but I guess you can just use Ext.Loader to get it:

Ext.onReady(function() {
// Your code here

As we have mentioned in our blog post:

Today’s preview release (and examples) contains almost all of the components that will ship in the final version. We’ve kept a couple back to give them some extra polish, notably Tree and Accordion.

Hi Tommy,

:"> My apologies, should have read the blog post! In my haste to try out the new version I skim read it (though I have read the overview in full). We've been eagerly awaiting Ext4 for ages, mainly for the full ARIA support :).

Many thanks,

Will the TreePanel support infinite scrolling as the Grid does?

I am also interested in knowing whether the TreePanel will support infinite scrolling.
