Field Detail

colsSmaller

protected int colsSmaller

The number of columns in the TextArea objects if the window is made narrower.

colsCurrent

protected int colsCurrent

The number of columns in the TextArea objects currently.

colsLarger

protected int colsLarger

The number of columns in the TextArea objects if the window is made wider.

widthSmaller

protected int widthSmaller

The width of the TextArea objects in pixels when they are colsSmaller columns wide.

widthCurrent

protected int widthCurrent

The width of the TextArea objects in pixels when they are colsCurrent columns wide.

widthLarger

protected int widthLarger

The width of the TextArea objects in pixels when they are colsLarger columns wide.

rowsSmaller

protected int rowsSmaller

Used to determine the number of rows that should be in the TextArea objects when the height of TextArea objects is made slightly smaller.

The TextArea.getMinimumSize method is applied to an object eight rows taller than the topWindow object. This allows room for bottomWindow and the buttons.

rowsCurrent

protected int rowsCurrent

rowsLarger

protected int rowsLarger

heightSmaller

protected int heightSmaller

This is the height in pixels returned by the TextArea.getMinimumSize method for a TextArea block rowsSmaller rows in height.

heightCurrent

protected int heightCurrent

This is the height in pixels returned by the TextArea.getMinimumSize method for a TextArea block rowsCurrent rows in height.

heightLarger

protected int heightLarger

This is the height in pixels returned by the TextArea.getMinimumSize method for a TextArea block rowsLarger rows in height.

initialized

protected boolean initialized

Set to true when the objects in the window have been initialized.

Some events related to window movement and resizing may be generated before the objects fully initialized. These should not be responded to as the sizes and locations have not yet been set.

communicationsWindow

public communicationsWindow(String name)

Method Detail

windowResizer

protected void windowResizer()

This method is called when the window is resized.

It examines the width and height of the windows to determine whether the TextArea objects should have their height and width changed.

addMessage

protected void addMessage(String display)

This method generates a message and adds it to the log and the Sys.output character stream.

Parameters:

display - name to be used on window

processKey

protected void processKey(KeyEvent e)

If the Delete or Backspace key is depressed, the last character in the bottomWindow textArea is removed.

If the Return key is depressed, the contents of bottomWindow are sent to the remote system and contents of bottomWindow are erased.

Parameters:

e - event to be processed

sendMessage

protected void sendMessage()

This method is called when the Send button is depressed on the form or the user depresses the Return key on the keyboard.

setDebugLevel

public void setDebugLevel(int level)

This method is used to control the amount of diagnostic messages generated.

A value of 0 means no messages are to be printed. Higher values generate larger amounts of messages.

Parameters:

level - value to be used for debugLevel.

getDebugLevel

public int getDebugLevel()

start

public void start(Socket inputSock)

This is the main method for creating the communications window and setting up the communications stream.

Parameters:

inputSock - socket to be used for communications
