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);
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?
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
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 a Jframe and i want to add inside 4 different jpanel.This is easy.
what is difficult is how can i change them dynamically with 4 other new jpanels and 4 other new jpanels?
I have try with BorderLayout but not working.
It's a wizard like but not the same.
I have a jpanel with jbuttons jpanel with a jtable jpanel with textarea and jpanel with jlabels. All this have to change with other 4 jpanels, where to look?
package GUI; import javax.swing.JFrame; import javax.swing.JPanel; import java.awt.Graphics; import java.awt.Color; public class gui5 { int x=0; int y=0; public static void main(String... x) {
[code]...
but just a Jframe is appearing no Jpanel no green color circle?What is wrong with code
I am try to do an application based in multiples JFrames, each one with its particular responsibilities, and use one JPanel as a menu with buttons that connect one JFrame to another, But this menu is instantiated at run in view (layout made by netbeans) the Main Jframe appears with its internal JPanel, but the instantiated JPanel does not appear or does not show it's buttons. (notice only run method in the second class):
JPanel Menu that will be used in all alone JFrames of application:
public class MenuSuperior extends javax.swing.JPanel { public MenuSuperior() { initComponents(); } private void initComponents() {
I am trying to develop a GUI through hard coding. I encountered a challenge:
I created a Jframe and onto this I added a JPanel. I assigned thge flow layout manager of the frame to null(because i want to do the positioning of my components manually)
The program is running perfect except when i click the maximise button of the frame, the JPanel does not change its size.
With Netbeans IDE - i found that the propert is Horizontal Resizable propert. I have tried to look for the method but in vain.
I am trying to develop identical things from hard coding and in drag and drop environment. so with drag and drop its easy but in hard coding how do I work it out?
Here is the code :
public class JPanelDemo { JFrame frame; JPanel panel; JPanelDemo(){ createFrame();
I am trying to put a button (in a container) on a jpanel in a jframe with a background but the container is covering up the background with white color.Below I have an excellent SCCE:
I trying to replace original (and empty) JPanel in JFrame with my own made one, components does no appear right, when I pass the mouse first button appears:
I am making a game in java and i want to make a title screen. What I am trying to do is make a jpanel and load another jpanel when a button is pressed in one of the japenls. Here is the code for the runner
import java.awt.BorderLayout; import javax.swing.JFrame; public class Runner extends JFrame { // Have these set up so they can be seen everywhere public static final int GAMEWIDTH = 540; public static final int GAMEHEIGHT = 710; static boolean loading = false;
[Code] ....
here is the code for the jpanel that loads the other jpanel
I have a Main() class that extends JPanel and I'm trying to add Card() that also extends JPanel.When I add a Card() or Main() object to the JFrame directly, it works fine. The problem arises when I try to add a Card() object to the Main() object.
I edited the code a little bit to make it easier to read so hopefully it's fine.
Main() code: public class Main extends JPanel implements Runnable { // HARDCODED OPTIONS public static final int WIN_WIDTH = 1200; public static final int WIN_HEIGHT = 800;
public static final int GRID_X = 9; public static final int GRID_Y = 5;
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(); } }
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:

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 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?
