Action Listeners in Card Layout.

[Nathaniel Waggoner]

Hi all.

Im working with a multi page GUI. Each page has numerous text entry fields (3-5) for specific pieces of data. Each page also has a number of buttons (confirm, reset, go back etc...).

The program is structured so that the button you click directs you to a specific and unique page. This goes for up to four pages before returning to the title page.

I am using the card layout currently, though I am not tied to it. My question is this:

What is the best way to detect actions within the currently viewed page so that i can direct people to the correct next page? I have the cardLayout aspect working just fine - ie all pages are in the card layout, and viewable if hardCoded to do so, but I'm not sure how to track events in this circumstance. I have seen this code on other forums (Credited to Fubarable on Java Forums):


Code:

  private void createGUI()
  {
    ActionListener firstPanelActionListener = new ActionListener()
    {
      public void actionPerformed(ActionEvent arg0)
      {
        JOptionPane.showMessageDialog(mainpanel, "Boo!", "Fubars Are Us", JOptionPane.ERROR_MESSAGE);
      }
    };
    mainLayout = new CardLayout();
    mainpanel = new JPanel();
    mainpanel.setLayout(mainLayout);
    mainpanel.add(new FirstPanel(firstPanelActionListener), "part1_layout"); 
}

The last line is the lline I am interested in, and I am going to play with that a bit and see if I cant apply it to what I am doing. My main problem is that it is "new FirsPanel(firstPanelActionListener)" - does this add both a new instance of FirstPanel and its assoiciate action listener? Curious if anyone else has suggestions?

Thanks,

Nathan.

Ok sorry for the double post: here is my cardLayout code;::

import java.awt.BorderLayout;
import java.awt.CardLayout;
import java.awt.Container;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.IOException;

import javax.swing.JFrame;
import javax.swing.JLabel;


public class DoseGardMasterGUI implements ActionListener {

		JFrame mainFrame = new JFrame();
		
		public DoseGardMasterGUI() throws IOException {
			page1 pageOne = new page1();
			// Pages Two:::
			page2 pageTwo = new page2();
			// Pages Three:::
			PageThreePtOneGUI pageThreePtOne = new PageThreePtOneGUI();
			PageThreePtTwoGUI pageThreePtTwo = new PageThreePtTwoGUI();
			PageThreePtThreeGUI pageThreePtThree = new PageThreePtThreeGUI();
			PageThreePtFourGUI pageThreePtFour = new PageThreePtFourGUI();
			PageThreePtFiveGUI pageThreePtFive = new PageThreePtFiveGUI();
			PageThreePtSixGUI pageThreePtSix = new PageThreePtSixGUI();
			PageThreePtSevenGUI pageThreePtSeven = new PageThreePtSevenGUI();
			// Pages Four:::
			PageFourPtOneGUI pageFourPtOne = new PageFourPtOneGUI();
			PageFourPtTwoGUI pageFourPtTwo = new PageFourPtTwoGUI();
			PageFourPtThreeGUI pageFourPtThree = new PageFourPtThreeGUI();
			PageFourPtFourGUI pageFourPtFour = new PageFourPtFourGUI();
			PageFourPtFiveGUI pageFourPtFive = new PageFourPtFiveGUI();
			
			
			
			
			CardLayout theLayout = new CardLayout();
			Container cardContainer = mainFrame.getContentPane();
			
			cardContainer.setLayout(theLayout);
			
			
			// addContents to Panels
			cardContainer.add(pageOne.getPanel(), BorderLayout.CENTER);
			
			cardContainer.add(pageTwo.getPanel(), BorderLayout.CENTER);
			
			// pageThree Pages
			cardContainer.add(pageThreePtOne.getPanel(), BorderLayout.CENTER);
			cardContainer.add(pageThreePtTwo.getPanel(), BorderLayout.CENTER);
			cardContainer.add(pageThreePtThree.getPanel(), BorderLayout.CENTER);
			cardContainer.add(pageThreePtFour.getPanel(), BorderLayout.CENTER);
			cardContainer.add(pageThreePtFive.getPanel(), BorderLayout.CENTER);
			cardContainer.add(pageThreePtSix.getPanel(), BorderLayout.CENTER);
			cardContainer.add(pageThreePtSeven.getPanel(), BorderLayout.CENTER);
			
			// page four Panes
			cardContainer.add(pageFourPtOne.getPanel(), BorderLayout.CENTER);
			cardContainer.add(pageFourPtTwo.getPanel(), BorderLayout.CENTER);
			cardContainer.add(pageFourPtThree.getPanel(), BorderLayout.CENTER);
			cardContainer.add(pageFourPtFour.getPanel(), BorderLayout.CENTER);
			cardContainer.add(pageFourPtFive.getPanel(), BorderLayout.CENTER);
			
		
			
			//cardContainer.add(new JLabel("Hello"), BorderLayout.CENTER);
			
			theLayout.first(cardContainer);
			mainFrame.setVisible(true);
			mainFrame.setSize(700,700);
			mainFrame.setResizable(false);
			
		}
		@Override
		public void actionPerformed(ActionEvent e) {
				}
		public static void main(String[] args) {
			try {
				new DoseGardMasterGUI();
			} catch (Exception e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
		
}

You may notice that two of the pages follow a different naming convention. I had partners in this project - basically they turned into flakes. In a mighty fit of lazieness im trying to not redo those two pages, because i dont wanna.

How best to handle this??

Thanks guys.

Welcome to the Ranch!

Can you please UseCodeTags? You can edit your post to add them.

I added the tags to the second post, and we can see how much better it looked, but I left the first post because it lacked indentation.

The first post seems to be indented now, so I added code tags.
