Learning Ext JS to customise dialogs
Having run through the various development articles on customising dialogs and working with XTypes the examples always include sample js file that handles the dialog, and extends functionality when creating a custom XType.
However, I find I get lost in points of the JS code as it is using Ext JS .
Now to fully use Ext JS one needs purchase https://www.sencha.com/products/extjs/newpkg/.
However all I want to do is understand how the examples work in the AEM documentation and be able to create simple extensions to XTypes for my custom components.
If I look for ExtJS tutorials they all lead to http://docs.sencha.com/extjs/6.0/ or a similar page on http://docs.sencha.com
This requires
I can get Ext JS 6.0.2 on a 30 day trial.
Is it necessary to purchase Ext JS 6.0.2 for AEM dialog development?
Am I in the right place to learn how to use Ext JS 6.0.2?
