Class AutoCompletionBinding<T>

  • Type Parameters:
    T - Model-Type of the suggestions
    All Implemented Interfaces:
    javafx.event.EventTarget
    public abstract class AutoCompletionBinding<T>
extends Object
implements javafx.event.EventTarget
    The AutoCompletionBinding is the abstract base class of all auto-completion bindings. This class is the core logic for the auto-completion feature but highly customizable.

    To use the autocompletion functionality, refer to the TextFields class. The popup size can be modified through its setVisibleRowCount(int) for the height and all the usual methods for the width.
