Example 1: A Simple Button.

Lets say we want to modify the interface to have a button that when pressed will center the display. We could create a new type of object called a dockexample1 in the following way:

import java         # import what we need
import javax.swing
import com


class dockexample1(com.hp.hpl.guess.ui.DockableAdapter):


      def __init__(self):
            # create a new button called center
            testButton = JButton("center")

            # every time the button is pressed, center the display
            testButton.actionPerformed = lambda event: center()

            # add the button to the toolbar
            self.add(testButton)

            # add the toolbar to the main UI window
            ui.dock(self)

      def getTitle(self):
            # define the title in the window
            return("dockexample1")

If we save this script to a file called example.py we can make use of it in GUESS by executing the file:

execfile(“example.py”)

and then creating a new dockexample1 object:

dockexample1()
