Swing/AWT/SWT :: Add Progressbar To Project For Listening Swing Worker Updates?
Feb 16, 2014I have a problem with progress bar implementation to my project. Let me explain it;
I have Jframe named GUI. Filled with 2 datechooser combo box and 1 Buton.
And i have a Swingworker class named "MySwingWorker" for my long running task just like this;
package exampleproject;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.Level;
import java.util.logging.Logger;
[code]....
Just i want add a progress bar for listening MySwingWorker's setProgress updates. When buton clicked swingworker should executed and progress bar should come to screen. I read many articles about that but not understand correctly. Because i am beginner in JAVA.
Question1: Should i (create new class) or (implement to current gui or swingworker class) for progressbar?
Question2: Should i fired progress bar first and execute swingworker from progressbar class? or should i execute swingworker first and fired progress bar later and how?
Swing/AWT/SWT :: Factory Design Pattern With Swing JDialog
Jul 26, 2014Is it a good idea to use the factory design pattern for say if I needed to create four different JDialogs for the same parent frame?
factory design interface
package client;
public interface Dialog {
void getInstanceOf ();
void initComponents ();
}
One of the four JDialog class would look something like this without the comments.
package client;
import javax.swing.JDialog;
@SuppressWarnings("serial")
public class AddCustomerDialog extends JDialog implements Dialog{
public AddCustomerDialog () {
//Some stuff goes here to set the settings for JDialog instance
[code]....
Of course you would have your factory class

View Replies View RelatedSwing GUI Programming
Jan 6, 2014I find myself asking these two questions because I see them as relating. First question is; I always write
Java Code: f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); mh_sh_highlight_all('java');
(where f is a JFrame object)
to set the close for the JFrame. What I don't get about this is what is going on in the parenthesis. I looked in the Java Documentation, and it says an int goes inside. In that case, I don't really get what the word JFrame is doing there. Overall, please explain what is inside the parenthesis of that line and why it has to be there.The second question is a generic question. I notice a lot of times an object will be created, and as its parameter, you will have to instantiate an object. an example would be
Java Code: Class f = new Class(new Object) mh_sh_highlight_all('java');
What does it mean when an object gets created inside of a new object? Why is putting Java Code: new Object mh_sh_highlight_all('java');
ever necessary when concerning the two parenthesis?

Why Should Swing GUI Code Be Placed On EDT
Oct 3, 2014According to what I read, "when programming in Swing, your GUI creation code should be placed on the Event Dispatch Thread (EDT). This will prevent potential race conditions that could lead to deadlock." (See below for code.)
Why is this? How could making a GUI lead to deadlock?
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}
});

Swing/AWT/SWT :: While Loop Does Not Run
Mar 11, 2014 I'm developing a Swing Project and I have a textarea in which the item names will be entered separating with commas.

Here is the code
String str = accessories.getText();
accessories.setText(str.toUpperCase());
String[] str_arr = accessories.getText().split(",");
float t1 = 0;
float t2 = 0;

Swing/AWT/SWT :: New Set Of Buttons
May 22, 2014So I have a Jframe that has a set of functions that act on a node. What I want to do is allow the user to expand the gui by creating new sets (copies) of these functions when they have more nodes.I thought of hiding extra sets and making it appear they are adding them by making them visible.
View Replies View RelatedSwing/AWT/SWT :: Need To Add ActionListener
Mar 25, 2015I am trying to implement user input in my dice rolling program but I do not understand where I need to add the actionListener. What I want the program to do is allow the user to click on each roll button and have the output be between 1 and 6. I figured I can put it in the "main" class due to the size of the program but I would like to know the best way to go about adding the actionListener into a sub-class for practice purposes.Here is my code thus far:
package com.jprogs;
import java.awt.*;
import javax.swing.*;
public class DiceGenerator extends JFrame {
DiceRollEvent dice = new DiceRollEvent();
// create the roll buttons
JButton roll_1 = new JButton("Roll #1");
JButton roll_2 = new JButton("Roll #2");
JButton roll_3 = new JButton("Roll #3");
JButton roll_4 = new JButton("Roll #4");
JButton roll_5 = new JButton("Roll #5");
// create output field for each roll

Aug 21, 2014I 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.

Creating A Excel From Swing?

View Replies View RelatedSwing/AWT/SWT :: Progress Bar Not Working?
Feb 14, 2014I'm trying to get a progress bar to work on my GUI.
This is what I have so far, the parameters are taken from another class that takes in an image in packets from a Raspberry Pi and stores them to a file on PC.
public void ImageInfoReceivedHandler(int sizeOfFile) {
progressBar.setMinimum(0);
progressBar.setMaximum(sizeOfFile);
progressBar.setIndeterminate(false);
[Code] .....
The println are printing out the correct values and they are being implemented in the methods, but nothing is happening in the GUI.
I have a thread setup in the GUI when a button is pressed
getImageButton.setText("Timer Started");
transmit = new transferImage(port);
lblImgProcess.setText("Getting Image, Please Wait");
transferThread = new Thread(transmit);
transferThread.start();
So the thread starts and image is then transmitted, does the progress bar need to be in that event handler?
Swing/AWT/SWT :: JTable With Fixed Row
Nov 9, 2008My JTable has a row, row number 0, which I always want to be at the top.I tried the following two approaches, both without success:
1- Use a custom table cell renderer for the header, and create a header of two rows. the second row is my JTextField.
Problem: I cannot get the JTextField to function properly. (I've seen examples with a checkbox in the header, but that one just reacts to a click somewhere on the header, my textfield must be editable).
2- Use the first row of the table. This works quite nice. However, I must prevent row 0 to be re-ordered when sorting the table.
I was thinking to add a prefix (either something like "___" or "zzz" depending on current sorting mode), but I do not know which methods to adjust for this exaclty.
Another approach would be to have N textfields above the JTable in some layout (or two JTable's on top of each other).
However, Then I would need to react to the re-ordering and re-sizing of all columns as well, which does not seem easy to me.

Swing/AWT/SWT :: Why Does ItemStateChanged Only Change Just Once
Mar 5, 2015I have a strange problems. Perhaps some of you already have had this problem before.
I have method which is suppose to check if the itemstate has changed. It ONLY works ONCE?
Thereafter, it does not matter how many times I changed the selection of the ComboBox.
Basically I have two Comboboxes.
1. If Combobox 1 is selected (e.g. Dogs, Cats)
2. Then get information from what ever the item from ComboBox 1 is selected, and display on ComboBox 2. (Dog Name, Cat Name etc)
E.g.
So If I selected Dogs on Combobox 1
Then display the Dog Names on Combobox 2.
If I then change and select Cats on Combobox 1,
then display Cat Names on ComboBox 2.

Swing/AWT/SWT :: Get Values In JDateChooser
Jan 15, 2007 I'm using Java Swings and MySQL database for my project. When I searched in the net for a datepicker in Java Swings I got one from a site which is Open Source. I've added that in my application. It is working fine. I can select the date from the date pickers and can view the values. I've the following problems in that.
1) I want to put the textfield to be read-only or the users cannot edit that part
2) I want to validate the fields before searching, for that i want to get the values in the jDateChooser.
