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));

Swing/AWT/SWT :: JTextField Size Changes With JLabel Text Length

Nov 11, 2014

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...

Change Text In JLabel When Button Pressed

Dec 4, 2014

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;

Change File Extension On Path Name In JTextField

Nov 3, 2014

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", "")

Swing/AWT/SWT :: Getting Jlabel Icons To Change Size With Window Resize?

Feb 20, 2014

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?

Swing/AWT/SWT :: How To Make JTextField Editable

Jul 10, 2014

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 ....

How To Make JTextField To Scroll Down Each Time New Message Received

Mar 31, 2015

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...

Set Icon Of File Depending On What Is In It - Like PNG

Feb 15, 2014

So I'm in the middle of creating a model program with voxels. I want to be able to see how the model looks like when I'm in for example my documents (not inside the real program). I want it to show an image of the model, just like a png file shows its image. I've tried looking around, but I've only found threads about changing exe files icon.

Image example:

So, is this possible in Java or do I need to use c/c++ (with JNA) to make this possible?

Or is it not possible at all?

Naming Objects Depending Of Times A Loop Have Gone

Oct 4, 2014

I know the normal way of naming objects is

Pipe pipe1 = new Pipe

but I want the objects to be made inside a loop and named after how many times the loop have been gone through so I tried

Pipe pipe(numberOfTimes) = new Pipe

where numberOfTimes was a variable counting the loops. This is not working.I need the naming to be pipe1, pipe2, pipe3 etc depending on how many times the loop have been pased

Scanner keyboard = new Scanner (System.in);
String morePipes = ("yes");
int dimRor;
int numberOfPipes = -1;

JComboBox - Different Choices Depending On Selection Made

Oct 5, 2010

I am stuck trying to build a relatively "simple" GUI. The GUI should have one JComboBox that allows the user to pick from one of three locations. Then based on their choice, another JComboBox should be generated with another set of choices. The key is that the second ComboBox should have different choices depending on the selection made in the first one. So, in theory, the logic should be something like:

//create new JComboBox array of strings "locations"
//create new JComboBox array of strings "costToTravelThere"
//if user picks location 1 from the first ComboBox
then add the second ComboBox with options specific to that first location
else if user picks location 2 from first ComboBox
then add the second ComboBox with options specific to that second locatoin

I understand how to do the basic stuff, like create the JFrame and the actual panels and ComboBoxes, etc. What I don't understand is how to implement the second ComboBox dependent on the first one. I'm not very experience with Listeners and such, and I'm sure that's a big part of this.

Swing/AWT/SWT :: Resize Application Depending On Screen Resolution

Sep 26, 2014

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.

Open A Form Depending On Username And Password Entered

Mar 14, 2015

I am creating a login form for my project and it works great,the issue is that i want to open up different forms dependent on the username and password that i enter.for example if i enter a password 'manager' then it should open the manager page,or 'employee' should open the employee page.

I'm thinking that it is just a case of creating another sql query but i have tried and i cannot see the solution,i can open the employee page by default but that is not what i am trying to achieve. I am using an sqlite database which holds the username and password.

Here is my code
 
private void btn_LoginActionPerformed(java.awt.event.ActionEvent evt) {
// code to login to the back office system
String sql =" select username,password from Employee where username =? AND password =?";//sql query
try{
pst =conn.prepareStatement(sql);
