Callin class from J button Click

Posted 28 February 2013 - 06:06 AM

See code below for JBUTTON addpatient. The code below the button code is for a class i created to display the addpatient GUI. WHat code do I need to add to addnew button to get the addpatient form to fire up.
//Add New Patient Button
                JButton addNew = new JButton("Add Patient");
                editandSearchOptionsPanel.add( addNew );
                addNew.addActionListener( new ActionListener()
                {
                	public void actionPerformed(ActionEvent add) 
                    {
                      // JOptionPane.showMessageDialog(null, "Adding New Patient") ;
                        frame.validate();
                       // addPatientgui addPatient = new addPatientgui();
                 }

------------------------------------------------------
 public static void main(String[] args) {
        //Schedule a job for the event-dispatching thread:
        //creating and showing this application's GUI.
    	
    	
    	//Set look and feel to NImbus.
    	
		try {
		    for (LookAndFeelInfo info : UIManager.getInstalledLookAndFeels()) {
		        if ("Nimbus".equals(info.getName())) {
		            UIManager.setLookAndFeel(info.getClassName());
		            break;
		        }
		    }
		} catch (Exception  UnsupportedLookAndFeelException) {
		    // If Nimbus is not available
			UIManager.getSystemLookAndFeelClassName();
		}
        javax.swing.SwingUtilities.invokeLater(new Runnable()
        {
            public void run() {
                createAndShowGUI();
            }
        });
    }
}

Just looking at methods and not code you just have to make a static call to createAndShowGUI.

orrect terminolgy
you can't call a class you call a method which resides in a class if it is static or belongs to an instance of a class (object)

And I don't see why AddPatientGUI should have static methods
If you want you can create an instance of that class, make the GUI setVisible(false) and toggle its visibility when required.
The class that has the actionPerformed() can receive that object as parameter to its constructor so the actionPerformed() can access it

It works by placing the following line of code in the addpatient button.
addPatientgui.createAndShowGUI();
Is this the correct way to have these talking to each other PBL or is the logic incorrect?

This is not the way I would do it at all

I would have

class AddPatientGui extends JFrame {

    AddPatientGui() {   // constructor
      .. create all the elements
      .. add all the component
      setDeFualtCloseOperation(...
      setSize(....
      ....  but NOT setVisible(true);
    }
}


Then in the class method that creates the class ABC that has the actionPerformed()

      AddPatientGui apg = new AddPatientGui();
      ABC abc = new ABC(apg);




class ABC {
   
      JFrame addPatientGui;
      
      // constructor
      ABC(JFrame addPatientGui) {
         this.addPatientGui = addPatientGui;
         ...
      }

      void actionPerformed(ActionEvent e) {
         ...
         addPatientGui.setVisible(true);


You don't need static method in AddPatientGui

I still cant get it to work that way. The code below resides in DocAppMainGUI for the addbutton.
addNew.addActionListener( new ActionListener()
                {
                	public void actionPerformed(ActionEvent add) 
                    {
                       JOptionPane.showMessageDialog(null, "Adding New Patient") ;
                        frame.validate();
                        addPatientgui.createAndShowaddPatientGUI();
                        
                        addPatientgui apg = new addPatientgui();
                      
                        addPatientgui.setVisible(true);
                     }
                } );


This is the code for addPatientgui

public class addPatientgui 
{
    public static void addComponentsToPane( Container pane) 
    {
        pane.setLayout(null);
        
        
        
        try
		{
		    for (LookAndFeelInfo info : UIManager.getInstalledLookAndFeels())
		    {
		        if ("Nimbus".equals(info.getName())) 
		        {
		            UIManager.setLookAndFeel(info.getClassName());
		            
		            break;
		        }
		    }
		}
