How to wire one pane to another

How to wire one pane to another - java

How do I wire output to paneWithList?
PaneWithList has a listener on its JList so that the selected row is output to the console. How can I direct that output to the JTextPane on output?
Could PaneWithList fire an event which Main picks up? Would PropertyChangeSupport suffice?
Main.java:
package dur.bounceme.net;
import javax.swing.JTabbedPane;
public class Main {
private static JTabbedPane tabs;
private static PaneWithList paneWithList;
private static PaneWithTable paneWithTable;
private static Output output;
public static void main(String[] args) {
tabs = new javax.swing.JTabbedPane();
paneWithList = new PaneWithList();
paneWithTable = new PaneWithTable();
tabs.addTab("list", paneWithList);
tabs.addTab("table", paneWithTable);
tabs.addTab("output", output);
}
}

Here's an example using the observer pattern, also seen here, here and here. Note that it would also be possible to listen to the combo's model.
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.beans.PropertyChangeEvent;
import java.beans.PropertyChangeListener;
import javax.swing.*;
/**
* #see http://en.wikipedia.org/wiki/Observer_pattern
* #see https://stackoverflow.com/a/10523401/230513
*/
public class PropertyChangeDemo {
public PropertyChangeDemo() {
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setResizable(false);
f.add(new ObserverPanel());
f.pack();
f.setLocationByPlatform(true);
f.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
PropertyChangeDemo example = new PropertyChangeDemo();
}
});
}
}
class ObserverPanel extends JPanel {
private JLabel title = new JLabel("Value received: ");
private JLabel label = new JLabel("null", JLabel.CENTER);
public ObserverPanel() {
this.setBorder(BorderFactory.createTitledBorder("ObserverPanel"));
JPanel panel = new JPanel(new GridLayout(0, 1));
panel.add(title);
panel.add(label);
this.add(panel);
ObservedPanel observed = new ObservedPanel();
observed.addPropertyChangeListener(new PropertyChangeListener() {
#Override
public void propertyChange(PropertyChangeEvent e) {
if (e.getPropertyName().equals(ObservedPanel.PHYSICIST)) {
String value = e.getNewValue().toString();
label.setText(value);
}
}
});
this.add(observed);
}
}
class ObservedPanel extends JPanel {
public static final String PHYSICIST = "Physicist";
private static final String[] items = new String[]{
"Alpher", "Bethe", "Gamow", "Dirac", "Einstein"
};
private JComboBox combo = new JComboBox(items);
private String oldValue;
public ObservedPanel() {
this.setBorder(BorderFactory.createTitledBorder("ObservedPanel"));
combo.addActionListener(new ComboBoxListener());
this.add(combo);
}
private class ComboBoxListener implements ActionListener {
#Override
public void actionPerformed(ActionEvent ae) {
String newValue = (String) combo.getSelectedItem();
firePropertyChange(PHYSICIST, oldValue, newValue);
oldValue = newValue;
}
}
}

I'd be use JMenu with JMenuItems with contents layed by using CardLayout rather than very complicated JTabbedPane(s)

For my own reference, and for anyone using the Netbeans GUI builder, this works so far as it goes:

The key being that panelWithList1PropertyChange is the listener on 'panelWithList' itself.
Because PanelWithList.firePropertyChange("list", -1, 1); cannot send Object nor String that I see, I'm not exactly sure how to get the value selected all the way from the JList up to the JFrame.
Hmm, well the API says yes it can send Objects. Have to check that out.
I think it's necessary to get some info about the model which the JList is using up to the JFrame. However, doesn't that break MVC? Or maybe that's the wrong approach.

Can't update the old JPane to Panel

The main purpose of my small app is to update the Panel, which is in the only one Frame, by pressing 'Enter' button pressed on keyboard.
Here are the classes:
Main - starts the app;
MainFrame - is the Frame with methods to update it;
PanelWithNoThreads - is the class of Panel, which is created while init of the Frame take place;
PanelWithNoFramesContr - is controlling everything what happens with PanelWithNoThreads.
PanelWithThread and PanelWithThreadContr - is the screen and it's controller, quite the same things as the previous pare is.
I'll put the code in the end of this post.
SO, THE PROBlEM IS...
When we start the app, everything works, and PanelWithNoThreads appears.
I press ENTER and after that my Frame shows me white screen...
So, how to solve this problem.

You need to call super () in the constructors of each of your custom JPanels.

Hit the add button twice you'll get 2 TABS not when I maximize it "Add TAB" moved to Middle and Textareas are in top.
I want jTextAtrea1 to expand till the bottom of the page during maximize and restore to actual size during toggle.

I want jTextAtrea1 to expand till the bottom of the page during maximize
Sounds like you should be using a BorderLayout for the panel you add to the tab. Then you add the text area to the BorderLayout.CENTER and the other components to the BorderLayout.NORTH.
It looks like your layout code is generated by an IDE. Don't use the IDE to generate layout code. Do the layout yourself and you will be in full control.

Automatically traverse a dynamically created jPanels for component values

I have a program that creates a dynamic amount of jpanels and components based on selection at the start of the program that is user-defined. having said that each jpanel and component is created with a loop making them all the same, and they are then put into a list (the JPanel's are put into a list).
Having said that I have been able to get the jpanel out and then grab the componenets and display them using System.out. but they are in a component object. How can I get the values of the components? Or am I doing this wrong?
Basically I am trying to have the tabs/jpanels based on user-definition automatically generate, which works. Then the user fills out some information and hits "Generate" which is where I then need to iterate through the tabs/jpanels/componenents and put them into the correct object.
Below is a working example of my program in a simplified for, with less tyteps of tabs (I only let the AP tab be created) and less options for the object classes:
There are two object classes APObject is extending Generic Object. MVCE is the start of the main program where it asks you a few user-defined questions which generate the Tabs/Panels. It then goes from InfoGathering.java to DataGathering where it creates the tabs and panels. The GenerateActionPerformed(ActionEvent evt) method is where I am trying to grab the information from the panel components and put them into the APObject or whichever object they need to go into.
MVCE:

int numGenerate[];

So with all the code out the way, as I have just revised all of this I will mention what the issue is again.
When I go to ConfigWindow from MainWindow to select Options, after selecting options, a method in ConfigWindow gets the value of the selected button, and then a method in MainWindow gets this value, and sets it to a variable within MainWindow. Then on clicking Apply in ConfigWindow, the method from MainWindow should be run, setting the MainWindow variable with the option selected, however it doesnt!
I have trimmed trimmed trimmed my project to its most basic form, and now it throws an error in netbeans on clicking apply, whereas before it just didnt do anything at all, no error in netbeans.
I hope I've managed to fulfil SSCEE here ... I'm trying!!!

Here is the source, progressed over what you posted, compacted into a single source file. There are still problems to be fixed, but I put debug statements (printing out values) that should help to point out why it is still not working. See further notes at bottom of post.

A single source file is needed for an SSCCE, but at 253 lines, it is not really 'short'. If you removed those (quite superfluous and irritating) auto-generated Netbeans comments and deleted the unnecessary code block to set a PLAF (which has nothing to do with this problem) it would probably be less than 150 lines of code, which is probably short enough to call 'an SSCCE'.
Use a consistent and logical indent for code blocks. The indentation of the code is intended to help people understand the program flow. In Netbeans, this is as easy as pressing the key combination Alt+Shift+F
That code seen above is how my current version of Netbeans formats the code, though I suspect that newer versions will leave out the first indent in order to have method signatures start at char 0 on a line (giving more width to display them).
I strongly suggest you put Netbeans aside for the moment. Until you are familiar with basic Java, it will just get in the way.
This source uses 3 frames. An application would (should) typically only have a single frame for the main application window. The other two might be put into a JDialog or a JOptionPane. See The Use of Multiple JFrames, Good/Bad Practice? for more details.

Got this sorted in the end, I was completely over thinking the issue.
