I'm using ExtJS 5.1. I have a panel with a definition of button in the items-section with a listerner for event 'click'. The 'this'-keyword refers here to the button itself. But I want a new ponent to my panel, so I need reference to this panel in the listener-function. 'this.getParent().add(...)' doesn't function, no function error, this.container.getParent().add(...) results in the same error. What is the correct way?

Using .up('panel') in the first argument of the click function, which is the button itself.

Or in ExtJS 5 define a reference property in your panel, and use

this.lookupReference('your_reference_in_panel');
