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...

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'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 have a textField in which I have text in. The text is enter customer name. I would like for this text to disappear whenever the user clicks on the textField to enter a customer name. I am using the automated swing gui builder in NetBeans. Is their some sort of feature for this under properties of the text field? If not then what are my other options?

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;

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 don't get what I missed in the code. I used the example of changing the text of a button by clicking on it, but instead I also added a JLabel and tried to make the button change its text instead, but it didn't work. What did I do wrong?
import java.awt.event.*;
import java.awt.*;
import javax.swing.*;
class Buttone implements ActionListener{
JLabel label;
JButton button;

I'm using NetBeans.
I have a JFrame with four JPanels, SensorLL, SensorLC, SensorCR and SensorRR. They are instances of the class SensorUI. Each has a JLabel called Sensor.
The class SensorUI has a method writeSensor that writes to the JLabel "Sensor". I will have four temperature sensors. I have not started the code to read the temperature sensors yet. I will have a timer that will run once a second. When it fires I will read the sensors and display the result in the
JLabel "Sensor" in each jPanel.
I use MyMain to call FrameDemo and create the JFrame and a method
in FrameDemo to add the JPanels using addObject.
I can use SensorLL.writeSensor will write text to JLabel Sensor while in Mymain.
Then I start the timer ReadSensor.
When it times out it calls SampleSensors
For an experiment, while in SampleSensors I try to write to the JLabel in the instance SensorLL with
SensorLL.writeSensor("xx_");
I can't because it says it can't find the symbol variable SensorLL in SampleSensors class.
How can I "get to" that JLabel text when ever I need to?
Java Code:
public class MyMain {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
//SensorUI SensorLL = null;
System.out.println("Start of main");
//Schedule a job for the event-dispatching thread:
//creating and showing this application's GUI.
FrameDemo.createAndShowGUI();

The code was,
messageLabel = new JLabel("Top buttons change the panel color and bottom radio buttons change the text color.");
messageLabel.setHorizontalTextPosition(SwingConstants.CENTER);
messageLabel.setVerticalAlignment(SwingConstants.CENTER);
The text always displays in top-center part of the center panel. i want to align it as center-center horizontally and vertically. The problem could be, bcoz the jlabel text is inside a constructor but im not sure. The whole code is
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class ColorSample extends JFrame {
private JPanel TopPanel;

I have four buttons with different names and depending on which button is pressed I want to change the label to be displayed. Center is the name of the label the other directions are buttons. The label should change if a different button is pressed. The error I get is that it cannot be converted to String.
public void actionPerformed(ActionEvent event){
Object source = event.getSource();
if (source == east){
center.setText(east);
}
if (source == west){
center.setText(west);

I'm currently learning Java and have been set an assignment that requires me to do the following:
Write an application that reads in a line length followed by individual lines containing text. No input line will be longer than the read in line length. In the text lines each word will be separated by a single space. The lines of text to be reformatted and then output so that the output lines of text have straight left and right margins. The last printing character in each line will be at character position (line length). In the text output the character '.' is to be used to represent the space character.

I'm trying to take this task on, but I'm unsure as to what exactly I'm supposed to do with part of it. For one of the methods I need to "work out how many extra spaces will need to be added to make the line width characters long.", how would I go about doing this?

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;

I have some project, and I wanted to show some long text stored in MySql database, on a java control such as JTextArea.Here is part of my code
infoPanel.add(new JLabel("Description"));
JTextArea desc = new JTextArea(7, 8);
desc.setText(c.getDescription());
desc.getFont().deriveFont(Font.BOLD);
desc.setForeground(Color.BLUE);
infoPanel.add(new JScrollPane(desc));
c.getDescription retrieves a long text from database. When it is displayed, it will be very wide, how can I make it more visible or break the text.

What I am creating is a clock. That goes round n round using "getcalendar". It's realtime, but the clock has a constant resolution of 800x800. I have carefully placed numbers from 1-12 on the clock using that resolution placing them pixel by pixel. Now if I resize the window, the clock resizes but the text, it fades away out of the screen because the resolution is too small.
This is how I draw them.
g2.drawString(six, 380, 750);
g2.drawString(twelve, 375, 70);
g2.drawString(nine, 30, 415);
g2.drawString(three, 725, 415);
g2.drawString(one, 570, 120);
g2.drawString(two, 690, 250);
g2.drawString(four, 685, 575);
g2.drawString(five, 570, 700);
g2.drawString(seven, 200, 710);
g2.drawString(eight, 80, 585);
g2.drawString(ten, 80, 235);
g2.drawString(eleven, 205, 115);
I understand why this is happening, obviously because the strings are in a certain place just can't understand how do I make them scaleable? Is there an universal formula? Or do I have to draw every string relevant to some mathematical equation regarding to the screen size.
For example : g2.drawString(twelve, diameter / 2, screenheight / 3);

I'm trying to run a downloaded exe program which uses the jre7 which I had to download beforehand. the font size stays at 6 or 8 even if I try to change it in windows settings. it's a high res monitor on a lenovo yoga laptop. is there a way for me to edit the java code and manually change the font size?
