Swing/AWT/SWT :: How To Make JLabel Hyperlink Change Depending On JTextField
Jul 30, 2014
This is a part of my program. When the user enters "Exam Schedule" in the JtextField and clicks the add button I want the link to change to a link that opens a local pdf file. And if the user enters "Academic Calendar" the Jlabel will be set to another link. So far this works fine but the problem is that if you erase the textfield and enter another value the link of the previous value will still be there.
public void actionPerformed (ActionEvent e){
if (e.getSource ==add) {
if (text.getText().equalsIgnoreCase("Exam Schedule")){
link1.setText(text.getText());
link1.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
[Code] .....

I want to create 3 JTextFields in a row with all being of equal size.But my first Text field gets so wide than the other two.After adding each component at a time and seeing what causes the problem I realized that if I type a long text for the JLabel that's when this problem occurs.If I reduce the length of the text in the JLabel JTextFields get into the sizes I want. Here's my code
import java.awt.*;
import java.awt.event.*;
import java.lang.Math;
public class Calculator1 extends JFrame {
JTextField value1=new JTextField("0");
JTextField value2=new JTextField("0");
[Code] ....
How can I stop the JTextFields changing size when I change the JLabel label1's text length...

I am trying to write an application where if you click and hold down on 1 button and move the mouse to another button and release the text on the 2 buttons should be switched around.I have a print line so I can se the text are supposed to get switched around but it is just not happening in the GUI.
I attached all my code in case the flaw was to find somewhere else in the code, but the functionality I am working on is the lines 76 to 121.
import javax.swing.BoxLayout;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JOptionPane;
import javax.swing.JPanel;

I'm trying to create a chess program in java swing, and for the board I'm using an 8 by 8 array of jlabels stuck inside a jpanel with a grid layout. I would like the board to change size when the window changes size, and the grid layout accomplishes this succesfully, until I add the actual icons to the jlabels. Then the board just stays a fixed size. Someone suggested I use their "Stretch Icon" class, found here:[URL] ...., so I tried initializing the icons using one of the constructors in the class (the one that takes an image name and a boolean value for whether or not you want the resisizing to be proportionate (to maintain the aspect ratio)). However, the same thing happened. The board appears, but it does not resisize. To attempt to fix this problem, I tried simplifying my code, reducing the program to two jlabels within the jpanel, for which I then tried to set the image in the same way. Here is my simplified code:
import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.ImageIcon;
[Code] ....
I'm misusing the stretch icon class, or just generally what's going wrong/how to fix it?

I'm having a hard time finding out the way to make JTextField editable. In what circumstances it can be disabled to write? [even the text in the field can't be selected, not to mention being uneditable. I did the followings to make it editable.
1. In its Properties panel(frame or whatever), checked the "editable" item.
2. In the code I made it run the code below :
void makeFieldsEditable(Boolean flag) {
Left_Name_field.setEditable(flag);
Left_Name_field.setEnabled(flag);
...
}
Is it related with the properties of the control(JTextField)'s surrounding panel, or even the largest containing frame? Using Netbeans ....

Ok, so I am trying to learn about JFrames and JPanels. I have figured out buttons, layouts, etc. What im having trouble with is accessing the label object from the ButtonHandler class since it is static and I need my JLabel to be non-static so that it can change. Basically, I want JLabel to change to a pre-determined text string once a button is pressed. Here's what I have so far
package makewindow;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
[code]....

I have a GUI that has three jTextFiled's. The first on gets filled in with a file that I choose and shows the path to that file with the file name
i.e. - c:
s34bil.exe
un estrun.i
I want to change the file extension from .i to .r in one jTextField and then .i to .o in another jTextField.
I am slowly learning Java. I have this coded in VB, but not sure how to do it in java.
Here is the VB script :
Dim thefile As String = txtInput.Text
Dim fn1 As String = My.Computer.FileSystem.GetName(thefile)
Dim fn2 As String = fn1.Replace(".i", "")

I have a jtextfield that I want to make invisible on start. I do not see an option for that in the design side under properties. I am a VB programmer and in VB there is an option under properties to make it visible or invisible.

I already done a lot of work(user lists, server logging, private messages), but im there is few thing i still dont know how to really implement and, of course my current program is far from beign decent, so i decided to start asking questions(so far i was just experimenting just using knowledge from book and some info found on Java API).
1. How can i make JTextField to scroll down each time new message received and log is already full? i mean visible part of it, so you don't need to scroll it yourself...
2. Why sequencer doesn't play MIDI if it is launched not by main thread?
3. What is good way to do user list with avatars? atm, i'm using regular JList and listening to selected values to open dialogs.
4. What is a good ways to implement sounds in application, other than MIDI? i know that i should just google it, but anyway.
You can check my source code for it by link. Chat client:URL...

I developed a swing application using group layout. It resizes when I resize the frame but when I change the screen resolution or when I run the application in a laptop which has small sized screen, the components over lap each other. I need my application to fit according to the screen resolution
The code is as follows
private void initComponents() {
jComboBox1 = new javax.swing.JComboBox();
jButton1 = new javax.swing.JButton();
jButton2 = new javax.swing.JButton();
jLabel1 = new javax.swing.JLabel();
jLabel2 = new javax.swing.JLabel();
jLabel3 = new javax.swing.JLabel();
[Code]...
According to the list item selected, an internal frame will appear in the desktop pane. I use group layout for that internal frame too.

So obviously I'm new to java and i need to write a program that gives exact change in quarters, dimes, nickels, and pennies. For some reason it seems to work correctly but the nickels never is correct and I'm not sure why, seeing as though everything else is.
Java Code:
public class Coins{
private int c;
public Coins(int coins){
c = coins;
}
public void calculate(){
int quarters = c / 25;

I'm having problems getting my program to display a JLabel. The program draws shapes of random size and color across a panel. I have this part working.

I have been reading several suggested solutions for implementing autocomplete for a JTextField. However, the documentation is a bit confusing to me. It seems like they mostly require switching to a JComboBox. Can I or can I not continue to use a JTextField and implement an autocomplete feature? I also saw what I thought was a built-in autocomplete "decorator" for swing objects (although it was not clear if it can be used for JTextField) but most of the implementations seem to start from scratch. Any simplest way to implement this (assuming those 2 conditions are not mutually exclusive)?

Create a dnd (dungeons and dragons) character creator and back ground generator, have it display and run on a gui, to start with i decided to creator the gui as i go so i can see the progress, first i tried eclipse and windows builder, well after 1 day of reinstalling windows builder in about 5 different ways from multiple guides and sometimes getting it to partly work ...
After doing some more research I have figured out how to get the main program to display the gui . Heres what i have:
package com.mrgreaper;
import javax.swing.*;
public class MainWindow {
private JPanel mainWindow;
private JLabel playerlbl;
private JLabel playerNamelbl;
[Code] .....
Now this works fine and the gui displays when the program is run but I can't change the text of any of the jlabels or textfield. If I try to do it in the main class i need to change them from private to public static but then in the form builder it says "cannot bind to static field *name of field*" but if i take static off then i cant change its value!
From what i understand this is because the window is an instance, so how to i change the value in that instance? I could put all my code in the one class, the one that creates the gui, but i really want it seperate, i would like the gui to update as the code runs... So how do i do it, how do i change the contents of jlabels on the fly, read the contents of text boxes on the fly etc....
I tried adding a getter setter
public void setCharFirst(JLabel charFirst) {
this.charFirst = charFirst;
}
in the MainWindow.class
Then i tried to set it from my main function
MainWindow.setCharFirst("test");
but it cant access it as my main function is static and it is not now can i make it static...

why JLabel setText method is not setting up the text dynamically even though i am calling repaint() once i set the text? Code snippet is below
Locale currentLocale = new Locale(panel.getCountryLocal(), panel.getCountry());
ResourceBundle messages = ResourceBundle.getBundle(Constants.messageBundle, currentLocale);
messages = Panel.getMessages();
String displayString = messages.getString("101022");

I am trying to get the data entered in a JTextField into a JTable but not clear on how. The LeftPanel is where the button is located and the RightPanel is where the JTable is. I want the actionPerformed to update the row of the JTable but I can't figure out how. There is another class that controls the GUI but did not think it was necessary to include. Also, I am aware that I am getting an error at the addRow line, can't seem to alleviate it.
public class LeftPanel extends JPanel {
private static final long serialVersionUID = -2311952438693382407L;
private RightPanel rPanel;
public LeftPanel(){
Dimension size = getPreferredSize();
size.width = 250;
setPreferredSize(size);
