JDialog Class (JAVA)
OBJECTIVES:
Since this tutorial has been designed for novices to help them learn the fundamental
functioning of JAVA Swing , Jdialog Pane and their structure in Java, the primary goals of
this research effort are as follows:
Understand how to create a dialog box based on the JDialog class.
Understand the interface provided by the dialog class that allows the
class using the dialog to know what operations a user performed.
Understand how a data model is used to transfer information between
the dialog and the main program.
The program you will work with implements a simple inventory system for Bart's
Butterfinger bar collection. The user can add and remove bars from the collection.
For this exercise, you will complete the functionality of adding a new bar to the
collection by completing the implementation of a dialog box.
CLASS NAME:
The class name for this tutorials discussion is “JDialog.”
INTRODUCTION:
JDialog class works as a general-purpose dialog which is used as a base to have
multiple lightweight components. The superclass of JDialogs is java.awt.Dialog.
JRootPane is its container and so provides a default window “close” button without
re-sizable buttons. It uses a JRootPane as its container, and it provides default
window-closing behavior. Since JDialog extends java.awt.Dialog, it has a
heavyweight peer and is managed by the native windowing system . JDialog class
can be summarized as summation 3 containers:
Windows Constants + Root Pane Container +Dialog in
java.awt -> JDialog in Swings
