how to make the tab key stop tabbing (ie. putting spaces) inside of a JTextPane. I do have it tabbing to the other componenets by setting up a Focus Policy class and FocusPolicy Keys but it still adds the space in the JTextPane even though it tabs out.

Here is a SSCCEE for pagination of jtextpane. it uses a stylededitorkit
My problem is if i change the content type to text/rtf or text/html it does not work.
Both rtfeditorkit adn htmleditorkit inherit from stylededitorkit so the result should be the same but it is not

I'm building a text editor. At this point, the editor should be able to read and write text and rich text. I create an instance of a RichTextEditor class that I created that extends a superclass I created (that extends JTextPane). Both my rich text and plain text classes extends the superclass I created. I use the this.read() to input my plain text from buffered reader. I think I need to use the read(fileinput stream, rtf document) method from type RTFEditorKit, but I cannot use that because it does not extend RTFEditorKit. I don't want to create a new class that extends RTFEditorKit because I need stuff from the JTextPane.
here are the classes on git... the super: TextEditorPane.java
The plaintext: TextEditorWrap.java
and the rich: RichTextEditor.java
I have fiddled with the read() method in different ways. In all cases, nothing loads. If I use the BufferedReader method, it doesn't give me an RTF, just the code for the RTF file.
How should I proceed? Do I create some sort of RTF interface and implement it?
I have a jTextPane set up and a panel with radioButtons. My jTextPane displays the contents of a text file I have chosen. The 3rd line, 4th index, displayed in my jTextPane specifies a value of type int. When I click my radioButton, I would like that value to increase by 1. So far, I have the following code. I tried to pane.setText(value + 1), but that doesn't seem to work. How do I update the value and display the updated value in jTextPane?
My code :
private final ActionListener actionListen = new ActionListener() {
for(String line: pane.getText().split("")){ String lineThree = line[3];
int value = lineThree.charAt(4); if(radioButton.isSelected()){
pane.setText(value+1); } }};
As I couldn't find a way to do the printing of multiple items on one page, I decided to test out my idea. I found that I could have a table in a JTextPane.
However, whenever I got to print, my table will vanish. It doesn't even need to go to the printer. Just bringing up the print dialog will make it vanish like tax money in D.C.
(Also, I'm not really that familiar with JTextPane and it seems harder than JTextArea. Which part is controlling the font of my regular text by the way? I think it might be tableParagraph but it could also be the base font. I can try and fiddle with both and waste paper but where the font is being set.
Setting the font with setFont() will vanish my table. )
Somehow, I'm thinking that the solution might be JTextPane.setContentType() or setEditorKit() or both. (I"m not that familiar with either, but I fear that it's only being set to handle text, hence any graphics are being lost.)
Here is my code:
import java.awt.*;
import javax.swing.*;
import javax.swing.table.*;

JTextPane textPane;

I 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?
Is 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
I would like to be able to change the locale in my Swing application at runtime and have all the text elements on the GUI update themselves with localized text from a ResourceBundle of the new locale.If there a simple way of achieving this without having to create an event model for all GUI pages?

View Replies View RelatedI 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?

According 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?

SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}
});

I'm developing a Swing Project and I have a textarea in which the item names will be entered separating with commas. The code has to check every element and fetch the price of it and calculate the total amount and display it in the text field. But Somehow it does not enter the while Loop? Why?
Here is the code

So 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.

I 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.
