Is it possible for a rectangle with dotted side be shown when dragging the mouse on a component?Just something like the one in the attachments, usually occurs in some graphics/pictures software.
This is right from a book I'm reading but it doesn't work. The problem is to write an application that lets you determine the integer value returned by the InputEvent method getModifiers() when you click your left, right, or middle mouse button on a JFrame.
This is the code copied directly from the book. What is missing:
import java.awt.event.InputEvent; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; import javax.swing.JFrame; public class JLeftOrRight {
i have problem with the following two java classes, driver class Reservations and Room class. When i run, it just show blank frame, tell me where i gone wrong.
import javax.swing.JOptionPane; import java.awt.*; import java.awt.event.*; public class Reservations extends Frame implements ActionListener { Color lightRed=new Color(255,90,90); Color lightGreen=new Color(140,215,40); Rooms room=new Rooms(5,3);
My panel named panelIncomeInfo are not showing the components that I have added.
public class PayrollGUI { private JPanel panelIncomeInfo = new JPanel (); private JPanel panel = new JPanel (); private JPanel panelPayCheckInfo = new JPanel (); private JButton close = new JButton ("Close");
I have been writing the below Dinner Menu Applet; however some text is not showing on the applet and it is not adding the 'desserts" section correctly especially the one that says "rice Pudding". I've tried it in so many different ways and it's sill not working correctly.
import java.applet.*; import java.awt.*; import java.awt.event.*; public class DinnerMenuApplet extends Applet implements ItemListener { Label dinnerMenu = new Label("Dinner Menu");
When i run the program it doesn't show all the text fields and labels and stuff but when i click btnTest_1 and go back to btnTest everything appears...
Java Code:
import javax.swing.*; public class Frame extends JFrame{ private JTextField textField; private JTextField textField_1; public Frame(){ setTitle("Multifunctual Calculator");
I'm displaying a table with several read-only pieces of data, and a checkbox field that toggles the row color. The background color for the checkbox is not toggling correctly. I put together a SSCCE:
If I comment out the Nimbus look and feel, it works as expected. I googled this problem and found one possible solution on Stack Overflow. Their suggestion is:It's a bug in the synth-installed renderer, quick hack is to force the rendering checkbox opacity to true: ((JComponent) table. get Default Renderer(Boolean.class)).setOpaque(true);
I tried using this line and setting the opacity to true, but it renders the background white. I'm using Java 1.7.0_25.
I have small problem in GUI. I have a text area which has to display my test orders now what is happening instead of the text showing up in the JtextArea its still printing to the console so this order code (yes i did not use proper code standers) runs though my order class fine but its not loading the text in the JtextArea
Order code
public static String testCase1(){ orders ords = new orders(); System.out.println("Test Case 1: " + " " + ords.getOrderDetails()); return " ";
Budget program. Here is my situation, I have 2 tabs in a GUI, one tab adds a transactions when the add button is clicked, and in the other tab displays a table showing all the transactions. In my code, I want it so that when the user chooses a deposit(combo box variable name = cbType, indexnumber for deposit is 0) it will add to the total and when the user chooses withdraw(index number is 1) then it will subtract it from the total. Here is the code.... (note as well, the code also adds a new row to the table)
So when I tested the program with 2 transactions, the first transaction was a deposit and the 2nd transaction was a withdraw. The end product was that both amounts were subtracted from the total. When I did a withdraw first and a deposit second, the amounts were both added together.
the below program is to read the time intervals (HH:MM) and to compare system time if the system time between your time intervals print correct time and exit else try again to repeat the same thing. By using StringToknizer class. and i have written like this
import java.io.*; import java.util.*; public class Main { static int k1,k2,v1,v2; public static void main(String args[]) throws IOException { DataInputStream o=new DataInputStream(System.in);
[Code] ....
but is showing correct for some inputs and wrong for some inputs ....
I cannot get my panels to appear in my GUI when I run my program. There is probably a really simple fix for this but it is taking me hours. This program is a working progress and I have just included two classes out of five. That should be adequate to diag my problem.
import javax.swing.*; import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; public class OrderCalc extends JFrame { private final int WINDOW_WIDTH = 200; private final int WINDOW_HEIGHT = 200;
import java.awt.*; import java.awt.event.*; import javax.swing.*; public class C1 extends JFrame { public C1() { JMenuBar b = new JMenuBar(); b.setBackground(Color.green); setJMenuBar(b); setVisible(true); } public static void main(String[] args) { C1 c = new C1(); } }
In my if statement on line 46 & 47 im trying to add the buttons to the screen if the player has lost and the "game over" screen have popped up. But the buttons aren't showing... what am i doing wrong?
I'm trying to show mysql data in JSF using this example [URL] .... . I figured out what <h:dataTable value="#{userBean.getUserList()}" var="u" border="1"> must be <h:dataTable value="#{userBean.userList}" var="u" border="1"> but getting error:

MyGraphics worked before I added a background but, even now when I take the background away it isn't showing up.
package com.snow.game; import javax.swing.*; import java.awt.*; class MyGraphics extends JComponent { //creating a class for graphics public void draw(Graphics g){ //calling Graphics making a new graphics (g) now you can use it to make objects g.drawRect(10, 10, 50, 50); //Draws a rectangle
I have one code [taking from on line SCJP exam preparation site]. I have 2 question in my mind:
1) addValue() is non static method then why it is running without object inside constructor. By this rule it should show compilation error. 2) With ref variable of parent always non overridden methods of parent run then it must value of 10 [If i forgot 1st point ]
But it is giving 40. Code is as below:
class Base{ int value = 0; Base(){ addValue(); } void addValue(){ value += 10;
How do I write a program that shows the max and the min value of a float integer? like for example in order to get the max value of a long integer we type System.out.println(Integer.MAX_VALUE); How would I do that for a float integer?
I'm attempting to add a Jpanel in a JFrame but it isn't working out.
import javax.swing.JFrame; import javax.swing.JPanel; public class stepone { public static void main (String[]args){ JFrame frame = new JFrame("CSC LAB 12"); JPanel colorJPanel = new JPanel(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
I have three classes.. 1. panel class 2. frame class and 3. tester class...I am creating the objects like so but when I add button to panel then panel to frame I am not seeing the button. here is my code
import javax.swing.JButton; import javax.swing.JPanel; public class Panel extends JPanel{ private JPanel p; private JButton b;
But apparently i was wrong and all i get is an empty JFrame and no Dialog. I even added my own subclass of SwingWorker in case a SwingWorker had to be created in order for a progress monitor to exist. How can I make it show?
