public SimpleViewer(java.awt.Container rootContainer,
                    java.lang.String preferencesPath)

setup and run client passing in parameter that points to the preferences file we should use.

Method Detail

setupViewer

public void setupViewer(java.lang.String defaultFile)

setup and run client, loading defaultFile on startup

getSwingGUI

public SwingGUI getSwingGUI()

open the file passed in by user on startup (do not call directly)

setRootContainer

public void setRootContainer(java.awt.Container rootContainer)

setupViewer

public void setupViewer()

initialise and run client (default as Application in own Frame)

main

public static void main(java.lang.String[] args)

main method to run the software as standalone application

executeCommand

public void executeCommand(int commandID,
                           java.lang.Object[] args)

Execute Jpedal functionality from outside of the library using this method. EXAMPLES commandID = Commands.OPENFILE, args = {"/PDFData/Hand_Test/crbtrader.pdf}" commandID = Commands.OPENFILE, args = {byte[] = {0,1,1,0,1,1,1,0,0,1}, "/PDFData/Hand_Test/crbtrader.pdf}" commandID = Commands.ROTATION, args = {"90"} commandID = Commands.OPENURL, args = {"http://www.cs.bham.ac.uk/~axj/pub/papers/handy1.pdf"}

Parameters:

commandID - :: static int value from Commands to spedify which command is wanted

args - :: arguements for the desired command

isProcessing

public boolean isProcessing()

addExternalHandler

public void addExternalHandler(java.lang.Object newHandler,
                               int type)

Allows external helper classes to be added to JPedal to alter default functionality.

If Options.FormsActionHandler is the type then the newHandler should be of the form org.jpedal.objects.acroforms.ActionHandler

If Options.JPedalActionHandler is the type then the newHandler should be of the form Map which contains Command Integers, mapped onto their respective org.jpedal.examples.simpleviewer.gui.swing.JPedalActionHandler implementations. For example, to create a custom help action, you would add to your map, Integer(Commands.HELP) -> JPedalActionHandler.

Parameters:

newHandler -
