does anybody know, how to fire a resize event on a html div?
i tried:

Ext.get("IdOfMyDiv").on("resize", function(){...})
... but it's not working...

The reason, why i need this is because my homepage is based on standard html with ExtJs support for several things. In this case the content of a div is changing dynamically when resizing the browserwindow, or when pressing a button, or when hiding some information, ....)

I know the event for browser-resizing but not the event for a div-container resizing....

thank you for your help and best regards!!
