Proper method to close a JFrame

Question

What is the most apropriate way to perform an action to close a JFrame when a button is click, and return the resource to the system?
Thanks.

Answer 1

U can first display the Welcomeframe whatever method u want to use
i assume u have a Button in WelcomeFrame which will invoke the DataFrame
If you have the following button write it as follows
JButton myButton = new JButton("Show Data Frame");
MyActionEvent lMyActionEvent = new MyActionEvent();
myButton.addActionListener(lMyActionEvent);In the action event class write down the following
class MyActionEvent implements ActionListener{
     public void actionPerformed(ActionEvent e){
          JDataFrame fJDataFrame = new JDataFrame();
          //Show or display JDataFrame here u can also do that from within the JDataframe class
          //Here get any values from fJDataFrame.
          //Because they will be lost once the frame is disposed
     //Line No 1:
          fJDataFrame.dispose();
}In the JDataFrame class set the following property
mJFrame.setDefaultCloseOperation(WindowConstants.HIDE_ON_CLOSE);Let me tell u what will happen.
When the JDataFrame is invoked from the action listener MyActionEvent the execution will stop at the Line now 1:. Until the fJDataFrame closes. Once the control comes back dispose the frame. Meanwhile do what u want in the JDataFrame until it is visible. U can later close your WelcomeFrame
Hope this helps
