I have been trying to get my radio buttons to display text when they are selected in a textbox but for some reason no matter what i try it wont display. Here is my code i have removed my attempt to get the action listener working.
package listVsSet.Desktop.copy; import java.awt.BorderLayout; public class ListVsSetGui extends JFrame { private JPanel contentPane; private JMenuBar menuBar; private JMenuItem mntnListVsSet;
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'm working on a GUI application, I'm building it based on an example of a image provided and I am having an issue with my radio boxes, well the easiest way to explain will be if you look at the too attached images , the example im working from has the radio-boxes transparent they are the same color as the background image, my radio boxes seem to sit ontop of the background image with their default grey border, How can i make my radioboxes blend into the background like in the given example?
Im using Netbeans GUI toolkip to build this app, for the background image in the jpanel i just created a label and set the icon to the image i wanted.
I have an assignment and one of the prompts is to do a binary search on an array if and only if the array of Strings is sorted. The binary search part I think I have completed, but it is the sorted array check that is throwing everything off. If the array is already sorted, return true; else, return false.
// Check if the array is sorted public static boolean isSorted(String[] arr) { //for (int i = 0; i < arr.length-1; i++) //{ //if (arr[i].compareTo(arr[i+1]) > 0) //return false; //} String[] arrSorted = arr; Arrays.sort(arrSorted);
I am writing code for a form in which i want to display data by selecting radiobutton.The code is working for single radiobutton but it not work when i select the other radiobutton.

the code is given below:]
private void jRadioButton1ActionPerformed(java.awt.event.Action Event evt) { // TODO add your handling code here: int LIMIT = Integer.parseInt(jTextField2.getText()); int ULIMIT = Integer.parseInt(jTextField3.getText()); { DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
I am using Java Swing to create a GUI. I have some radio buttons on a JFrame that gets opened when the user makes a certain selection. I want to read a config file to have the radio buttons selected or deselected when the form is opened to indicate the current state of the radio button based on the saved config file.
How do I go about setting the radio button as selected (visibly selected) when I open up the JFrame?
I was trying to use RadioButton.setSelected(True); but this doesn't actually visibly select the radio button.
I am making a quiz app and stuck with this problem. User is presented with question with options he select one radio button and move on to next question by clicking next button.
Now when user clicks on the previous button to change the previous selction , I want his previous selection to be shown selected. How can I do that.
How do you make it so that you can select 2 buttons in a radio button group? for example: If I have 7 radio buttons, and I want to be able to select 2 of the 7 instead of 1.
I'm trying to make it to where each button is supposed to display the country's flag and a description. As of right now, I've hit a roadblock and haven't been able to get past it. As of right now, without the errors in the setDisplay method where setTitle and the other two are undefined for that type, I get each country's name listed as a radio button.
However, I haven't been able to get anything else to display.
import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Flags extends JFrame{ private String[] flagTitles= {"Canada", "China", "Denmark", "France", "Germany", "India", "Norway", "United Kingdom", "United States of America"}; private ImageIcon[] flagImage= {
I'd like to disable/enable SelectManyCheckbox and the SelectOneMenu based on my selection. I have two radio buttons to be selected whether A or B. The SelectManyCheckbox and the SelectOneMenu should be disabled at the first run. When the user selects “A” the SelectManyCheckbox and the SelectOneMenu should be enabled and if the users selects “B”, the SelectManyCheckbox and the SelectOneMenu should be disabled and the items should be empty. I tried to use <f:ajax render="certificates"/>, but it doesn't work properly.
What would be the simplest way of creating a Dialog that can add TextField dynamically based on whether a radio button option from the dialog box is selected. I thought of JOptionPane.showMessageDialog and adding a JComponent though I would not be able to add a TextField on the fly and I would not be able to add ActionListeners. The dialog would initially contain some radio buttons, labels and textfields.
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've spend an hour or two, pasting fragments from tutorials and nothing changed.
Well - i have GUI, that have JComboBox with two elements: String[] fedoras = { "Fedora 19", "Fedora 20" }; JComboBox fedora_list = new JComboBox(fedoras); fedora_list.setSelectedIndex(0); fedora_list.setBounds(120,170, 170,25); fedora_list.addActionListener(this); this.add(fedora_list);
Below i have normal button (named Update) with "update" set as ActionCommand. This button after clicked should check which value from list is selected and perform different operations for that elements. But it's harder than i thought.
Code for update button:
public void actionPerformed(ActionEvent e){ String cmd = e.getActionCommand(); (...) else if ("update".equals(cmd)){ String selectedFedora = (String) fedora_list.getSelectedItem(); if (selectedFedora.equals("Fedora 19")) {
[code]....
- after user clicked Update button, button should check which value is selected in JComboBox (fedora_list). - if Fedora 19 is selected and button clicked, then action in Xterm - if Fedora 20 is selected, this same action in Xterm is performed, but for Fedora Linux 20
The problem is - i don't know hot to code Update button to check which value from fedora_list (JComboBox) is selected and perform other actions for every element on List.
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?
This is the first time we are using 2 different classes. This is the code I have so far. What I am having trouble is doing the calculations and storing the value into the planet the user selected and keeping it going. I will attach the instructions ....
public class FakeGravity{ // Instance variables private String planet; private int VelocityDecay; private double BouncinessFactor; // default constructor public FakeGravity(){
I just learned about 2D arrays and am still trying to get a grasp on the concepts. I'm a little confused by how you return all the values in a row to add up and display the sum if the row is entered by the user.
import java.util.*; public class RowSum { public static void main(String[] args) { Scanner s = new Scanner (System.in); int userpick = 0; int sum = 0;
I have an ArrayList of JTextFields in a CAMSetup1 class that contains a bunch of named JTextFields: Layer_textField_1, Layer_textField_2, Layer_textField_3, ... etc
I would like to check the .isEnabled status of a particular JTextField in that ArrayList from my main class by passing the name of the JTextField to a method in the CAMSetup1 class as a string
The peice of code calling the method from the main class is something like this:
if (CAMSetup1.getFieldEnabledStatus("Layer_textField_1") == true) { data.writeToFile(CAMSetup1.getFieldText("Layer_textField_2") + " LAYER 2 LIST FILE "); }
The method for checking the .isEnabled that I have so far is:
public boolean getFieldEnabledStatus(String textFieldname) { boolean status = false; //<need code here> return status; }
I'm trying to come up with a method that would validate each turn a player makes. For a turn to be valid, it has to only contain numbers from 0 to 3(inclusive) and at least one digit must not be 0. Here is what I`ve come up with so far. For example, with "303" as the number and "101" as the turn, the turn would be valid and my method should return true, but it does not.
public static boolean turnIsValid (String number, String turn ){ boolean rep=false; int pos1=0; char min='0'; char max='3'; while(number.length()==turn.length()&&pos1<turn.length()){
I tried to make a program that takes a string str, and char a and checks how many times the char is used in the string.
Example: the string Welcome and the letter e, is 2 times. so the program should print 2.
It compiles but when I run it and enter the information, i cannot get the printing line out.
Heres my code:
import java.util.Scanner; class program { public static void main(String[] args) { Scanner user_input=new Scanner(System.in); String str; String b; System.out.print("Please enter a word");
