in short, only those options ExtEvents, UniEvents and that is the secret of the unigui, because there lives all the power of javascript
the vast majority of demos are limited to showing the other properties of the components, and for those who already come from delphi there is no complication in that,
the problem is the js codes
I also agree if there was a megademo with examples of each property of the options of the
ExtEvents, UniEvents
would be great
