Methods

 o addNotify

Creates the frame's peer. The peer allows us to change the appearance of the frame without changing its functionality.

Overrides:
addNotify in class Window
 o isModal
  public boolean isModal()
Returns true if the Dialog is modal. A modal Dialog grabs all the input from the user.

 o setModal

Specifies whether this Dialog is modal. A modal Dialog grabs all the input from the user.

 o getTitle
  public String getTitle()
Gets the title of the Dialog.

See Also:
setTitle
 o setTitle
  public synchronized void setTitle(String title)
Sets the title of the Dialog.

Parameters:
title - the new title being given to the Dialog
See Also:
getTitle
 o show
  public void show()
Shows the dialog. This will bring the dialog to the front if the dialog is already visible. If the dialog is modal, this call will block until the dialog is taken down by calling hide or dispose. It is permissible to show modal dialogs from the event dispatching thread because the toolkit will ensure that another dispatching thread will run while the one which invoked show is blocked.

Overrides:
show in class Window
See Also:
hide
 o isResizable
  public boolean isResizable()
Returns true if the user can resize the dialog.

 o setResizable
  public synchronized void setResizable(boolean resizable)
Sets the resizable flag.

Parameters:
resizable - true if resizable; false otherwise
 o addWindowListener
  public synchronized void addWindowListener(WindowListener l)
Adds the specified window listener to receive window events from this dialog.

Parameters:
l - the window listener
 o removeWindowListener
  public synchronized void removeWindowListener(WindowListener l)
Removes the specified window listener so that it no longer receives window events from this dialog.

Parameters:
l - the window listener
 o processEvent
  protected void processEvent(AWTEvent e)
Processes events on this dialog. If the event is an WindowEvent, it invokes the processWindowEvent method, else it invokes its superclass's processEvent.

Parameters:
e - the event
Overrides:
processEvent in class Container
 o processWindowEvent
  protected void processWindowEvent(WindowEvent e)
Processes window events occurring on this dialog by dispatching them to any registered WindowListener objects. NOTE: This method will not be called unless window events are enabled for this component; this happens when one of the following occurs: a) A WindowListener object is registered via addWindowListener() b) Window events are enabled via enableEvents()

Parameters:
e - the window event
See Also:
enableEvents
 o paramString
  protected String paramString()
Returns the parameter String of this Dialog.
