Swing/AWT/SWT :: Reading From HTMLEditorKit Doesn't Display Text While In Text / HTML Content Type?
Apr 24, 2015
I'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 {
int returnVal = fc.showSaveDialog(window);
if (returnVal == JFileChooser.APPROVE_OPTION) {
StyledDocument doc = (StyledDocument)text.getDocument();
HTMLEditorKit kit = new HTMLEditorKit();
BufferedOutputStream out;
[Code] ....
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 have my below Swing GUI code in which I want to read and display some contents present in text file say (test.txt) which is located in my local disk (C: est.txt). My pane tab 2 is divided into two halves horizontally. How can I read and write the test.txt file contents under the tab tab2 in the first half of the pane(where currently it is 2 written)?
Sample test.txt present in my local hard disk location username:test1 Password:test1 DataBasename: testDB
CODE FOR TABBED PANE
import javax.swing.*; import java.awt.*; public class SplitPaneExp { public static void main(String[] args){ Runnable r = new Runnable() { public void run() { JFrame frame = new JFrame("WELCOME");
This is sort of like the last problem I had but it's all about the formatting at the end. I have a file that reads something like:
Name a bunch of text here and perhaps a second or even a third line
I need to output this as:
Name; "a bunch of text here and perhaps a second or even a third line"
Right now I find 'Name' and it outputs:
Namea bunch of text here and perhaps a second or even a third line
How would I add ";" and quotes in the middle? I can imagine that I may need to find name, then skip to the next line and just add name manually as the variable output of the search string.
This is where I am now
public static void main(String[] args) { boolean output=false; String name=""; String junk="CHAMBERS"; TextIO.putln("Search for a name"); name = TextIO.getln(); TextIO.readFile("doc.txt");

So I'm almost there, but those dange double Names are killing me. I tried to add a bit of code where:
So currently I am trying to use a JTextarea to display text and I then prompt users to type in certain words. I have a few problems that I have encountered. Firstly when I use setText and then if I say setText again after that it erases the previous text that was set. Ideally I want to set text once per line in my whenever a certain task is fulfilled. For example if the text says enter y/n, I want the program to go to the next line once I say y or n. Another problem of course is when I setEditable to true I can edit the whole textArea. I just want to be able to edit the line which I am currently at. Is there anything that I can use that mimics the ACM console program, or even the console down below in most IDE's where everything appears to be done line by line?
Also here is an example of what I am trying to do, along with comments:
Java Code:
console.setText("Math is good!"); console.setText("What is 2+2?: "); //using getText gets the whole line, I want //everything checked after the colon. That is where the input will be if(line==4){ console.setText("That is correct"); } else { console.setText("That is incorrect"); } //previous text lines are overriden with new ones. I don't want that, nor do I want to be able to edit the //whole JtextArea mh_sh_highlight_all('java');
JFrame parentFrame = new JFrame(); File f12=new File("E: ewfile.txt"); JFileChooser fileChooser = new JFileChooser(); fileChooser.setSelectedFile(f12); fileChooser.setDialogTitle("Specify a file to save"); int userSelection = fileChooser.showSaveDialog(parentFrame);

I want to save selected text file as html file in target directory....
I am using a JFrame with JPanel (with radiobuttons and jtextfields) and am wanting to get data from a text file (around 100 words) and input 4 words at a time into my gui. I have been trying to do this by filling an string array with the data, (no problems here) then using jTextField to read the array. (having a few problems in this area though) Am about 80% there...but just wondering is there a better way to approach this problem, that is, inputing words into gui, refreshing, input 4 new words, refreshing, etc.
Is there a way of detecting the file's type (whether it is a pdf, jpg, png,or anything else) by reading the content of the file. We could read the extension of file to determine it's type, but then extensions can be forged too. So I would like to know if the content inside a file is of a particular type or not. I'm not sure about this, but I have heard somewhere about each having having a specific kind of header which determines its type. So is it possible to read that header and determine it using a program?
I'm supposed to write a GUI application letting the user enter a file on the text field and display its hex representation in a text area and vice versa.
Here's my code:
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ package hexconvertor; import java.util.*; import java.io.*; public class HexConvertor extends javax.swing.JFrame {
I'm working on Java-GUI implementation in Ubuntu. Used font-type in the application throughout is "Arial". At earlier stage of application it was the same font-type("Arial"). As the implementation grew the font-type has been changed automatically to another font type. It seems Serif-font type.
Now I could not able to figure out the problem; why it is so.
Note- I used HTML code also for setting font style of Dialog box messages and buttons. This is the only point which I figured out. Can it is ?
I am in the middle of creating a chess application, and am currently working on laying out a list of moves on the right of the actual board. Specifically, I want to have a JLabel that says "moves" on top of a JList that contains the moves, on top of two buttons, labeled "<" and ">" respectively, to which I will eventually add functionality to take back and un-take back moves. Currently I have the first two parts down, but when I add my buttons,the other components are getting messed up.
I have all of these things in a vertical BoxLayout inside of a JPanel with a fixed width of 70, and a height that varies according to the size of the window (I overrode the getPreferredSize method of the JPanel). The two buttons are within their own JPanel with a grid layout with one row and two columns. Then I basically just add the moves list label, the movesList, and the panel housing the buttons to the larger panel, in that order.
However, I am encountering two problems. One, the buttons display the text "... " instead of "<" and ">" as if there is not enough room, although I'm pretty sure three periods take up more space than one less than or more than sign. The next is that, without the buttons at the bottom, the label reading "moves" is appropriately centered (or left aligned, I can't tell which) over the movesList, and you can read its whole text. However, when I add in the buttons at the bottom, the label of the top shifts over to the right and then reads "mov..." because it has run out of room.
Here is my code:
//move list movesListLabel = new JLabel("Moves"); //the components for the actual movesList come from another class with an object called pen, but I don't think this is the problem listModel = pen.getListModel(); JList movesList = pen.getMovesList(); JScrollPane listScroller = pen.getMovesListScrollPane();
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 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?
This is the code that I wrote but I have two problem with two buttons one of them ... I want to delete the selected text inside the text Area which represented as b[8] and the other button that I want to select parts of the texts which represented as b[0]....
<%@ page import="javax.print.*"%> <%@ page import="javax.print.attribute.*"%> <%@ page import="java.io.*"%> <%out.println("Printing..."); String filename = "c:/20140505_3_40.txt";//this is the text file i want to send to printer // am using tomcat 8 PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
I would like to create a program that takes some files and modifies them in this way: The files should contain text formatted in this way:
############## #various comments# ############## something{ identifier=1234 anotherIdentifier=1235 anotherOne=12345 //and so on... }//I need only this
#Comments are sometimes made this way
somethingAgain{ #comments that explains what's below them I:dentifier:something, I, do, not, need #see ^that A:notherIdentifier:boolean //and so on.. }
And I have to make so that the numbers contained in something{} in all the files don't match. I could ask to make so that the input file is only one, and it is formatted this way:
identifier=1234 anotherIdentifier=1235 anotherOne=12345 //and so on...
but I don't know how to do the rest of the program... That's what I've done (the names of the classes, package etc. are in Italian and there's some useless code that NetBeans prevents me from deleting):
package confronto; import java.awt.Color; import java.io.*; import javax.swing.*; public class confrontoTesti extends javax.swing.JFrame {
I have a main class that hold the frame and paints, a class for drawing my game, and an image that is drawn too. I want to count the amount of times I click on this "android" (right now it counts if i click the screen) but the text from the class Game doesn't update.
androidX = Main.width - android.getWidth();
doesn't work. In my head the image should be inside the borders but it isn't. Have I calculated the pixels wrong or am I missing something?
public class Main extends JPanel{ public static final int width = 600; public static final int height = 600; Game game = new Game(); Android android = new Android(); public void paint(Graphics g) { super.paint(g); game.render(g); android.render(g);
But the naamSpeler.laatKaartenZien(), which returns a string, doesn't show on the label. Is there a way to call a method and use a html text on a label?
The name of the thread should be "call method in html text on label"
I wish to display a progress bar during a lengthy file translation process. When I created a ProgressBar class to do this and tested it with a short test program, it seemed to work fine. But when I add my ProgressBar class to a package containing various other classes, put that package in a jar file, and then execute the class using the progress bar from a menu in my main program, the frame of the progress bar shows up with the appropriate caption but the JLabel, JProgressBar, and JButton are not displayed. I have gone over my code numerous times and checked that the ProgressBar class constructor is getting the proper arguments.
// package gov.nasa.jpl.ephemeris; import java.awt.*; import java.awt.event.*; import javax.swing.*; /** * Progress bar with message text above the bar and a Cancel button below it */ public class ProgressBar extends JFrame { private boolean _cancelled = false; private JProgressBar _progressBar = null;
[Code] ....
I have also been wondering whether I need a separate instance of the border for each panel, or whether I can just create one instance and use it for all three panels.
01. pickup the selected text file and read the line by line and output the text in to visual text pane.
what i did:.
01. I wrote code that read the text file and output in to jave console/ also some of the interface.
the code read txt file:
Java Code:
String fileName = "C:/Users/lakshan/Desktop/lawyer.txt"; File textFile = new File(fileName); Scanner in = new Scanner (textFile); while(in.hasNextLine()){
[code]....
so it will read any text file dynamically and output to the text pane in interface. I think scanner code must be execute after the select the file from the browser and set the scanned result in to variable. then later out put the var as string in some jswing component?
my code is below and i want to read only integers.BUT the text file is starting with text and it stops executing without reading the numbers.Also i want to add the 3 parameters of each line.
try{ File fl = new File("C:/Users/Mario/Desktop/testing.txt"); //BufferedReader rd = new BufferedReader(new FileReader(fl)); Scanner sc = new Scanner(fl).useDelimiter("s+"); LinkedList<Integer> temps = new LinkedList<>(); sc.useDelimiter(System.getProperty("line.separator")); while(sc.hasNext()){
