Try debugging it to make sure that listBox is not null when you try to add items to it.

[java]ListBox listBox = nifty.getCurrentScreen().findNiftyControl(“myListBox”, ListBox.class);





listBox.addItem(“b”);

listBox.addItem(“c”);

System.out.println(listBox);[/java]



I’ve



[java]de.lessvoid.nifty.controls.listbox.ListBoxControl@1ee9cbee[/java]



:confused:

iif I get the items I have “b, c” … it’s strange

When do you do that code? In the bind event?

an element of nifty call a function. But even if I put it in another class it does not work

Here is the URL to the default control - ChatControl. It should provide a decent example of how it can be done.

This is the Java code.
