Changing output of ListView, when the list is empty?

[Jerouris]

Hello Wickets,

Does anyone know can I change the output of a listView when the included
list is empty?
It would be nice for example, when the list is empty, to show a message type
Sorry, no results.

Best,
Jerry

You can have:

add(listview = listview(...) { // Show list only if it has stuff
  isvisible() {
 return !getList().isEmpty();
  }
}
add(label(..., Sorry, no results) { // Show label only if list is empty
  isvisible() {
 return listview.getList().isEmpty();
  }
}

Thanks Martin,

It's a nice idea to create a panel with these to components.
