public class ScreenDesigner extends Object implements IScreenDesigner, org.eclipse.swt.events.FocusListener, org.eclipse.swt.events.KeyListener, org.eclipse.swt.events.MouseListener, org.eclipse.swt.events.MouseMoveListener
Screen designer interfaces to the TerminalWindow to perform drawing of rectangles and to interface with the mouse and keyboard. Note that the display cannot be drawn correctly if the font size is smaller that 4 pixels vertically or horizontally.

- Returns:
- the phase of the line style.

x
- X position, pixel.y
- Y position, pixel.returnValue
- Returned screen rectangle in [0].- Returns:
- -1 for none, otherwise the handle.
