public class Zarbiff
extends Frame

Main program which is executed to run ZARBIFF.
The static Main method is where control actually begins. This method creates an actual Zarbiff object. This object is the control panel. It contains the menus and buttons. All events eventually reach the control panel and are handled here unless they are caught by one of the children.

Zarbiff()

activateWindow(GraphWindow): null for none active
clipboard(): Get the graph which is stored in the clipboard.
getfilter(String): Get a filter from a file.
getpict(String): Load an image from a file.
handleEvent(Event): Main event-handling method.
initToolbar(): initToolbar must be called to set up the toolbar at some point after the main window is set up so image loading works.
keyDown(Event, int): Handle a key down event.
main(String[]): Kind of like C.
newWindow(): Create a new document window.
newWindow(GraphInterface, String): Create a new document window to view the already existing graph g.
restoreWindow(GraphWindow)
setLocalDir(String): Set the directory where the user's local .zarbiff file and custom filters reside.
setclipboard(GraphInterface): Set the graph which is stored in the clipboard.

  public void restoreWindow(GraphWindow _gw)

activateWindow

  public void activateWindow(GraphWindow _gw)

null for none active

newWindow

  public GraphWindow newWindow()

Create a new document window.

newWindow

  public GraphWindow newWindow(GraphInterface g,
                               String title)

Create a new document window to view the already existing graph g.

getpict

  public Image getpict(String filename)

setLocalDir

  public void setLocalDir(String dir)

Set the directory where the user's local .zarbiff file and custom filters reside.

main

  public static void main(String args[])

Kind of like C. This is the method that executes when the user types `java Zarbiff someargument'. If they include an argument this is given to this method in the args[] array.
