Method Index

o button(Event)
Handles the actions associated with the various buttons.
o getAppletInfo()

Constructors

o SecantGrapher 
  public SecantGrapher()

Methods

o getAppletInfo 
  public String getAppletInfo()
Overrides:
getAppletInfo in class ZoomGrapher
o makeGraphWindow 
  protected GraphWindow makeGraphWindow()
Returns an instance of SecantWindow, cast to a GraphWindow.

Overrides:
makeGraphWindow in class ZoomGrapher
o makeControlPanel 
  protected Component makeControlPanel()
Lays out the buttons that we use in this applet

Overrides:
makeControlPanel in class ZoomGrapher
o button 
  public boolean button(Event e)
Handles the actions associated with the various buttons. All the buttons used in Grapher appear here too, and are handled by the superclass. The graphing panel is our inherited copy of Grapher.gw, which is a GraphWindow, so this method needs to cast Grapher.gw to an SecantWindow to use the features of that class.

Overrides:
button in class ZoomGrapher
o handleEvent 
  public boolean handleEvent(Event e)
Handles the checkbox to toggle the display

Overrides:
handleEvent in class Component
