Im writing a program that records the score in a dart game. One component of the program is a stage where players enter their name.This information needs to be displayed in another part of the program. These two components are in two different classes. My problem is I dont know how to get that information from one class to another.
Im using Jtextfield in Jframe to record the information.
I want the text that the user inputs into the JTextField in the user input panel to be what shows up in the JTextField in the totals panel.
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Scanner;
import javax.swing.*;
import javax.swing.border.TitledBorder;
[Code] ......
I know that I will need to take advantage of the get and set methods, could I get an example of this? How to write the code.
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?
View Replies View RelatedI 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");

How can I stop the JTextFields changing size when I change the JLabel label1's text length...
how to put the output the the text area this is the code .

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.
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)?

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 {

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 ....
I recently began writing a much larger program than I will show. I have boiled the problem down to this SSCCE.
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.JTextField;
import javax.swing.SwingUtilities;
class TextButton extends JRadioButton
[Code] ....
What i wanted was a JRadioButton with no label carrying around a JTextField. When I added a restore configuration feature in the real program, i found that the text destined for the JTextField was being echoed into the JRadioButton.
Perhaps it is obvious but i sure don't see what I am doing wrong. I am using Java 1.7.0 for development if that makes a difference.
I want to have JTextField automatically highlighting the current values for overwriting when the box is selected. Is there a way to do this? It seems like something that might occur in an action listener.
View Replies View RelatedI need to take the value of what's typed in my JTextField, and once the submit button is clicked, I want to add that string to my JComboBox list items.
Depending which RadioButton they selected, I need to put the team in HOME or AWAY teams, and so on and so on, until they continue clicking submit.
I am designing a advanced search option in a java project with sqlite in NetBeans. there are 5 different JTextfields and 5 columns, I want to populate JTable with corresponding matching criteria. If a JTextfield is empty then it should select all items of that column.
query i was using is:
String val1=txt_billing2.getText(); //five input fields
String val2=txt_station2.getText();
String val3=txt_invoice2.getText();
String val4=txt_amonth2.getText();
String val5=txt_umonth2.getText();

but when i leave a JTextfield empty it shows no data in JTable. only method i know is to use if else conditions but that generates 5!= 120 conditions!!!
Using the code from the Java Docs (listed below) I am getting behavior that was a bit unexpected. The only changes were to add JTextField and additional output within the ComponentEvent handlers. Run the code and when the frame appears, think of each side as North, South, East (right side) and West (left side) as you are looking at it. This was run using JDK 1.7.0_25.
Run the code.
1 - Click the East edge (right) of the frame and drag to be wider or more narrow. Only the "Resized" is executed for all components which makes sense.
2 - Click the West edge (left) of the frame and drag to be wider or more narrow. This time "Resized" is executed for all components EXCEPT it is "Moved" for JFrame. Why is it "Moved" here for JFrame but not in Step 1?
3 - Click the South edge (bottom) of the frame and drag to be taller or shorter. This time only 2 components are affected. JPanel is "Moved" while JFrame is "Resized".Why isn't both JFrame and JPanel just "Resized"?
4 - Click the North edge (top) of the frame and drag to be taller or shorter. This time only 2 components are affected again but the output is slightly different. JPanel is "Moved" while JFrame is BOTH "Resized" and "Moved".
There just doesn't seem to be consistency here. What are the guidelines or criteria for when these Events are to be executed?

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));

I have a swing jFrame set up with a control group which contains 3 radio buttons.
When one is clicked it sends its label to a jtextfield in a different class i have code parsing text by a term

Scanner s = null;
try {
s = new Scanner(new BufferedReader(new FileReader("/Stage_One.txt")));
s.useDelimiter("*");
String total = (s.next());
Pattern p = Pattern.compile("[]+");

I just need to know how to access the jframe variables (textfields, panels and such) so i can use their inputs in code to filter a text file.

View Replies View RelatedI'm working on a simple text editor, and I'm currently saving the contents of my JTextPane in a file using an HTMLEditorKit (text is a JTextPane):
private void save() throws IOException {

if (returnVal == JFileChooser.APPROVE_OPTION) {
StyledDocument doc = (StyledDocument)text.getDocument();

The problem I'm having is that after opening a file that I saved, it does not display (if I disable text/html, it displays the entire html code, but when I re-enable it, nothing displays at all.) Am I loading it wrong, or am I setting the JTextPane's text incorrectly? Or is it, perhaps, another error that I didn't catch?
I am building a chat server/client and would like to have it so when a user sends a message, the message pops up in the main chat area beside their name, which I would like to be in bold font. Something like "Alan: Hello, how are you?". I can't find a way to do this with a text area or on a string. Do any swing components suitable for use as text areas support bolding of certain sections of the string that you will set to it?
View Replies View RelatedI'm trying to create a Java swing chess application, but would like to divide the GUI part of it into at least two different classes (possibly more later, but I'm not sure yet). Currently I have a mainGUI class and a ChessBoard class, both of which extend JFrame. I want the main GUI class to contain a JPanel which will house several components, including a JPanel originating from the chessboard class that contains the actual board.
Is there any way to do this? I tried just creating a ChessBoard object in my main GUI class and then adding it to the component, but I got an illegal argument exception, because apparently you can't add one JFrame to another. How to do what I'm trying to do, or just how to split GUIs into multiple classes in general?
In the book we made a GUI which has 2 buttons, a label and a panel (the panel is a subclass of JPanel). What the program does is the following: When I press one of the two buttons, in the panel there is a rectangle that changes its color. When I press the other button it has to change the text on the label. Now the problem is that when I start the program, the FIRST time I press the button on which the label must change, this also changes the color in the rectangle, which it should not (I also noticed that when i FIRST click the rectangle shifts a little bit to the left). After that the program works fine.
Here is my code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class TwoButtons{
JFrame fr;
JButton labelButton;
JButton colorButton;
JLabel label;

1. Tried to use setLayout() but it wouldn't let me. Have imported libs
import javax.swing.*;
import java.awt.*;
but it doesn't work. It only worked when I extended a class with JFrame. Why do I have to do it? I already have a JFrame instance:
public test(){
JFrame frame = new JFrame();
frame.setTitle("Workshop");
frame.setBounds(500,300,400,300);
frame.setVisible(true);
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
....
}
This code runs smooth, so it's confusing for me that it lets me create a JFrame object, and put buttons onto it, but it wants me to extend the class onto JFrame class in order to use a method.
2. I've read somewhere that AWT is old and should not be used anymore. Is there a diagram or a list with objects and properties that are manipulated only by Swing so that I could concentrate only on those? For example (made up list):
JPaper -
- width, setWidth(x)
- height, setHeight(x)
- position, setPosition(x,y)
- color, setBackground(RGBa)
- acquire, add(subordinate component)
- deprive, remove( subordinate comopnent)
- etc...
JSticker -
- width ...
- height ...
- write, setText(String)
- etc...
I am new a creating GUIs and am not quite sure how to correctly make one. I have done the inheritance parts, and created two extra appliances: a washer and dryer. Now Creating the GUI ....
Here are the instructions to my project.
Introduction to GUIs (+ some inheritance)
For this assignment, you are going to create a user interface that interacts with the setters and getters of some classes that you will create.
First, create an abstract class called Appliance. This abstract class should have two attributes (dealing with household appliances) and two abstract methods called turnOn() and turnOff(). These methods should return void.
Then, create two subclasses of Appliance that represent household appliances (like a Refrigerator or Stove ((don't use those!))). These subclasses should have two attributes that are specific to the various appliance. Each subclass should implement the turnOn() and turnOff() methods. These methods should print to the command line some information about the appliance as it turns on and off.
Now, the fun part! Create a GUI interface!
Your window should have two panels: one for each appliance subclass. Each panel should have 4 textboxes (with appropriate labels) to receive/display information that correspond to the 4 attributes (2 from Appliance and 2 from the subclass) for each subclass.You also need 2 buttons on each panel: A Get button and a Set button.
When the Get button is pressed, the text boxes should be filled with the information from the instantiated object of the appropriate subclass. When the Set button is pressed, the object should then contain the information contained that the user has altered.
In your main method, you should create an object of each subclass, and prefill it with information (either using the constructor or the setters), then display your GUI. You should now be able to get and set the information for your objects from the GUI.
At least one of your attributes for each subclass should be numeric
Note that you will need to handle incorrectly formatted input (You can use exception handling to do this if you want to. Wrapper classes also will work)
If there is text in the boxes when the "Get" button is pressed, it should be overwritten by what is in the object. Remember that these two panels should both be on screen at the same time.
You don't need 2 different windows, one window: 2 panels.
