All Implemented Interfaces:

Focusable, GConstants, processing.core.PConstants

public class GTextField
extends GEditableTextControl

The text field component.
This control allows the user to enter and edit a single line of text. The control also allows default text and a horizontal scrollbar. can be created to manage either a single line of text or multiple lines of text.
Enables user text input at runtime. Text can be selected using the mouse or keyboard shortcuts and then copied or cut to the clipboard. Text can also be pasted in.
Fires SELECTION_CHANGED, CHANGED, ENTERED, LOST_FOCUS, GETS_FOCUS events.
The focus events are only fired if the control is added to a GTabManager object.
