public class JTerminalScreen
extends javax.swing.JPanel
implements net.sf.freehost3270.client.RWTnAction, java.awt.event.KeyListener, java.awt.print.Printable

A SWING component that interactively renders terminal screen contents and handles user to terminal interaction.

The terminal is first rendered to a buffered image and then, whan a component repaint is requested this buffered image is painted on the given component's graphics context. In case if a default font size is changed, the JTerminalScreen adjusts it size in order to feed the grown terminal screen size.

Since:

0.1 RHPanel
