Creating Simple Text Editor - Delete Selected Text Inside Text Area
May 13, 2015
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]....
I am working on a personal project and want to create a text editor to write my code. I am wondering how could I read the last input from the user and if say it was an open curly brace {, then like netbean's my editor will supply the closing curly brace. My java experience is limited but I have tried to read key board input and a few other options that did not work.
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?
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 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?
I'm having a problem with a small text editor I'm trying to create. I have implemented a panel of labels, containing line numbers, on the left of a scrollable text area. The panel is designed to size such that it fits the larger numbers whenever they appear. It does that very well, actually, until either one of the scrollbars appear. As soon as one does appear, it immediately shrinks in width. The horizontal scrollbar even blocks the view a little, making it impossible to see what you are writing on the very last line.
import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Main implements KeyListener { public static JPanel tab = new JPanel(false); public static JTextArea text = new JTextArea(); public static JScrollPane scroll, reflex; public static JPanel lines;
[code]...
Explanation of the code: There is a main panel which embodies a text area and another container filled with labels of line numbers.Both the text area and line number panel have scroll panels attached. They are synchronized, in order to scroll at the same time.
The main class contains a static function "position" which generates a GridBagConstraints, created for the convenience of single-line creation of constraints.It also implements the KeyListener interface, and waits for change in the amount of lines inside the text area. Afterwards, it changes the panel of labels accordingly.
The program below compiles and functions correctly for the most part. It is supposed to be a simple GUI Text Editor with Edit and Format functions. The content pane is supposed to be a scroll pane, however no matter how much I type into the editor, the scroll bar does not appear. Also, the none of the functions under the "Edit" menu work.
This shows a nice text area and an input field underneath it.The getGameHistory() method just returns a long string detailing the current game.Is there a way of just showing the text area without the input field underneath?Can the text area also be used for input instead?
how to put the output the the text area this is the 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 interns; /** * * @author JosephP */ import javax.swing.*; import java.awt.event.*; import java.awt.*;
This is the code that i have used to delete particular String from text file. It works absolutely fine on eclipse and netbeans.. But on deployment(in tomcat) it fails to delete message/rename or delete original file even though all permissions for modifying the files in the folder has been given to all users.
I have a requirement where in the content of the text area is dynamically populated from the database. I am able to successfully retrieve and display the data on the text area.
However when the content is too large, I am not able to dynamically set the height of the text area. When I try to display the same as a label, the display is flawless, dynamically sets the height as per the content. So, I tried to create a label, with same content and dynamically bind the height to the preferred height as below, but it doesn't work.
// Generate User Note Description TextArea textArea = new TextArea(); Label text = new Label();
// SETTING THE TEXT TO A LABEL TO RETRIEVE THE HEIGHT text.setText(usrNotes.getNote().trim());
How can I read a text file present in my local directory say (C://test.txt) , iterate and populate the values of test.txt into a text area of the JSP page?
Contents in the test.txt file: username:test password:test123 domain:test321 DBname:testDB
I have problem with my simple program. I tried put some text in my text area using button1 but textListener in RighButtons is always null and it's give me NullPointerException.
WriteToArea - interface public interface WriteToArea { public void add_a(String text); } BaseFrame public class BaseFrame extends JFrame{
In my application, some text should be added to a text area in response to a click on a button. So as an action listener to this class, I made another class which implements the ActionListener.
Inside this class, I have obtained the text which I want to be added to the text area. But the text area is in another class and for the action listener I wrote another class.
Now the problem is that when I try to add the text to the text area by the following line of code, it says that textArea_1 can not be resolved or is not a field.
Java Code:
ParentPanel.textArea_1.setText("Name:"+ncrarray[0]+" Code:"+ncrarray[1]+" Rank:"+ncrarray[2]); mh_sh_highlight_all('java'); What should I do about it?
Even if I try to write a method like the following in the class in which the text area is created, it gives the same error.
Java Code:
public void printTextArea(String text) { textArea_1.setText(text); } mh_sh_highlight_all('java');
The text area is present inside a constructor of the class. I am writing the method outside the constructor (ofcourse).
I have to write a gui program where I can enter a file name and then it gets displayed in a text area when I click Open. Conceptually, I do not get this. I was thinking of appending the text file into a string or something, but I guess I'm confused on how it all works and how I can open the text file. Not asking for the code, but just a compass or something.
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?
Write a program that reads in a line of text and then outputs that line of text first in all uppercase letters and then in all lowercase letters.
INPUT and PROMPTS. The program prompts for a line of text as follows: "Enter the text: " and then reads in an entire line of text as a String .
OUTPUT . There are four lines of output . The first line is "The text in all upper case is: ". The second line is the line that was read in, displayed in all uppercase. The third line is "The text in all lower case is: " and the fourth line is the original line that was read in, displayed in all lowercase.
CLASS NAMES. Your program class should be called ShoutAndWhisper.
This is what I have so far:
import java.util.Scanner; public class ShoutAndWhisper { public static void main(String[] args) { Scanner scannerObject = new Scanner (System.in); System.out.println("Enter the text: "); scannerObject.next(); System.out.println("The text in all upper case is: ");
I'm using JBoss 7.1.1.Final. I'm writing a Spring 3.1.1.RELEASE web application and have a massive amount (~5MB) of text output to send to the browser. I would like the browser to display the output as it is generated, but right now, the browser only displays everything after the servlet's doGet method completes. Here's my method …
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 am trying to read a text file into Java and split the text into tokens. Eventually I want to be able to count the number of instances of a specific word. However, at this point, when I run the file, all I get is the location of the file rather than the text in the file.
import java.util.*; import java.io.*; public class textTest3 { /** * Prints the number of words in a given file * * @param args * @throws IOException */
I try to bind the text-property of a selected cell of a TreeView to a label. So if the user click on a cell in the treeview the label should show the cell text. Now I am quite confused about the options I got to do so. Should I use label.textProperty().bind( ... ??? ... ) The treeview.onMouseClicked()property? or something different?
why this code doesnt work? Its suppose to be a simple frame with a button that puts text to the frame when u click it. The problem is actionPerformed method, when it tries to call the stuff inside the constructor it all goes wrong. I switched the method body with a system.out.println() and it all works fine.
import java.java.awt.Label; import java.awt.Button import java.awt.BorderLayout; import java.event.*; public class TheClass implements ActionListener { public TheConstructor() {
