How To Sync Up Value Of JSlider With JTabbedPane
Apr 11, 2014
I have a problem here ive been trying to figure out and im not sure what the problem is. I have a JTabbedPane with an amount of tabs that match the amount in a JSlider. The amount can change dynamically.
What i want to do is have it so that if someone clicks the second tab it goes to value 2 on the JSlider etc... Should it be simple as adding a changeListener to each and going
slider.setValue(tabs.getSelectedIndex());
tabs.setSelectedIndex(slider.getValue());
It doesn't seem to have any effect. Is it some kind of scope issue maybe or is this code wrong?

public class MyColorChooser extends JPanel implements ChangeListener{
private JSlider redSlider;
private JSlider greenSlider;
private JSlider blueSlider;
private JTextField txt1;
private JTextField txt2;
private JTextField txt3;
private final Color[] colorValues =
[code]....
Do i have to make a new no argument constructor for my sliders?

I have a program ive been working on and it works, but the flags in the runnables seem to shift the output down 1. for instance i commented playa3. start(); to see whats going on, if i just run playa1 i got no issues, as soon as i enable playa2, i get this output:
Game continues...
Dealer places King and Queen on the table.
Game continues...
Dealer places Queen and Ace on the table.
Player one with 'Ace' places his card on the table.
Player one with 'Ace' wins the current deal.
King Queen
Game continues...
Dealer places Queen and King on the table.
Player two with 'King' places his card on the table.
Player two with 'King' wins the current deal.
Queen Ace
the second time the dealer deals, player one places his cards on the table when he was supposed to do that for the first deal which he didnt. the last line there, (king queen) is just a print statement that is referring to the dealers hand that, that iteration is responding too. below is my code, i
import java.util.*;
import java.io.*;
import java.lang.*;
public class P5
{
public static int i, count, dealerFirstCard, dealerSecondCard, player1, player2, player3;
public static String cardSet [] = {"Ace","King", "Queen"};
public static volatile boolean dealerFinished= false;
public static volatile boolean playersFinished= false;
[code]....

Modify the program in Assign4 to synchronize access to the instance variable, balance. Save the program as SyncBank.java. Because balance is a double and not an object, it cannot be used as the monitor. Use synchronized methods or synchronized blocks of code as appropriate. Simultaneously test two threads as was done in Assign4. Because the threads can complete too quickly to determine if they are interfering with each other, delay the adding of a deposit by inserting the following code within the synchronized block or method:
try {
Thread.currentThread().sleep(10000); //sleep for milliseconds
}
catch(InterruptedException e) {
}
My code attempt so far:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import java.net.*;
import java.text.DecimalFormat;
public class SyncBank extends HttpServlet //throws ServletException, IOException
[Code] .....

basically I would like to know how to to the following Java. Example... Say I have one JComboBox, and it is populated with 10 items which reads from a text file ("apple","banana","kiwi","orange","grape fruit"), and the other JComboBox holds the price ($1,$2,$4, etc etc...you get the drift).
How do I make in such a way when I select for example banana from the JCombobox that it syncs the other JCombox to the correct price?
Basically syncing the two JCombobox so that you do not need to select the price yourself - it does it automatically for you.

I have been trying to learn how to use the TabbedPane GUI. I can get the tabs to show up, but the buttons I have placed in each tab do not show up. Why this is not working. I assume that, for some reason, the buttons are not linking with their respective panels, or the panels are not linking to the respective tabs.
import java.awt.BorderLayout;
import java.awt.GridLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTabbedPane;
[Code] ....

Is it possible to programmatically simulate a click event on a tab (JTabbedPane) to trigger its changeListener once a button is clicked ?

Consider this simplistic scenario,
tabbedPane.addChangeListener(new ChangeListener() {
@Override
public void stateChanged(ChangeEvent e) {
}
});
How do I trigger this listener, say when I return from a JDialog, I can't make this listener to swing into action even I tabbedPane.revalidate();

I think, is of concern to a large Swing-JTabbedPane users and which does not appear in the Sun-Oracle tutorial [URL]
How to add functionality to the hidden 'Action Listener' of JTabbedPane to obtain the two following functionalities, when passing from Tab_Panel_1 to Tab_Panel_2 ?
- To call a home made function as very last task when the 'tab selection change' is triggered and just before control and visibility are leaving Tab_Panel_1.
For example : Calculations and table fillings need to be operated. One assume that the fact of leaving Tab_Panel_1 (by clicking another 'tabPanel') means that the input data in Tab_Panel_1 are completely introduced and that calculations and/or table fillings may occur (to be used by other 'Tab_Panel's).
- At the moment of entering Tab_Panel_21 or Tab_Panel_22, the very first task is to use the previous calculation results and/or table fillings as input parameter of methods own to Tab_Panel_21 and Tab_Panel_22.
For example, these data are further processed and used to feed a graph, different for Tab_Panel_21 and Tab_Panel_22.
tabbedPane.addChangeListener(new ChangeListener()?
SwingWorker?
SelectionChanged?

No matter what I did, and searching for every piece of setBackground, The background color of the JTabbedPane is light blue.

WindowFocusListener,
WindowStateListener {
Container mainPanel;
JPanel bluePanel = new JPanel();
CloseButtonTabbedPane tabbedPane;
