I want to add a picture to my buttons. The end statement will be a path finding algorithm that will with show the picture on all the buttons on the shortest path. I am using a constructor at the moment passing a picture object to it. It is suppose to work but its not on line 30...
Java Code:
import java.awt.Color;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.*;
public class Screen implements ActionListener {
public JButton[][] b=new JButton[20][20];
Can I add actionListener to a button component without creating a reference to it? Look at my code below:
public void init() { setBackground(Color.red); //Create the layout setLayout(new BorderLayout(20, 5)); //Add buttons add("North", new Button("Red")); add("South", new Button("Yellow")); add("East", new Button("Cyan")); add("West", new Button("Magenta")); add("Center", new Button("White")); }
Or should I just do the usual instance.addActionListener(this) like myButton.addActionListener(this)?
import javax.swing.*; import java.awt.event.*; public class menu { public static void main (String[] args){ JFrame frame = new JFrame("Menu"); frame.setVisible (true);
I've got my clear button to work on most of the stuff I want, however I cant figure out how to fix the price to stop adding up. e.g. hit a button image with a price of 599.99, hit the clear button to empty, select price of 599.99 again then it display 1199.98.
I want to add a button who refresh the tree the problem that i have not "DefaultTreeModel" in my class to do this ((DefaultTreeModel) jTree1.getModel()).reload(); and i try this jtree.updateUI(); but not work ....
I'm making a Pacman look-a-like game, now I'm making the map out of an 2D array (as a grid). I already initialized the 2d array spots with "0" and "1". I managed to do this but now I'm stuck.
I want to use the "0" and "1" to print the map. For example the "0" are grass and the "1" are walls. The map should be printed within a JFrame. And I would like to make the width and height 32x32 pixels.
I searched on the internet and i found a couple of example codes but non of it seems to work properly. This is the code I'm using to make the 2D array and initialize the spots.:
public class Level1 extends javax.swing.JFrame{ final int ROWS = 17; final int COLS = 17; int[][] field = new int[ROWS][COLS]; public Level1() { initComponents(); setLocationRelativeTo(null);
I am in the process of creating a Tic Tac Toe game with a GUI using JButtons that will hold the X and O pictures. I have the picture appearing when i click it once but it jumbles up all the other buttons which is why i have to run the method resetAllButton() to set everything back. Once i click the x again it puts everything back how it is supposed to be and works normal. How can i get this to work in one click.
import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.ImageIcon; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; public class TicTacToeGui extends JFrame implements ActionListener {
I am trying to make a japplet that has open, zoom in and zoom out buttons for pictures. I am not sure how to go about an open button that will read the file. I have the picture url hard coded in the file to open but would like an open button with a file/folder dialogue.
The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.
I am using JS, how we can make focus to a button during onload, the button need to get focus which is in tabbedPane tab Name : (Search Critera1) using javascript.
I have a JButton with a .PNG icon on it. I want to get that button click in actionPerformed Method but Jbutton have no Label... How i will know that which button clicked?
I am creating a mad libs type program. This section of code is for the user to be able to make their own mad lib template (that people will be able to fill out later). The normal blanks in a mad lib are for verb, noun, adjective, adverb, etc. I cam up with 13 or so of these buttons, but it would be nice that if the user wants to add a button that they think we missed, such as 'Person in the Room' or 'Silly Location'...that the user would be able to do this. I sort of pictured there being a button that says 'add button' or something like that. Is there a ways to do this with the way I've set things up?
public class MadLibs { public static void main(String[] args) throws IOException { //////////////////// //TEXT PANE WINDOW// //////////////////// //Set up a JTextPane object : The JTextPane is a specialized form of the JEditorPane //designed especially for the editing (and display) of styled text. final JTextPane pane = new JTextPane();
I dont know why this does not work. A string called naam is empty in the beginning. Thats why its NULL on the button. But if I give it the value "karel", it still states null on the button, how can I update this?
Im trying to use num as the text on the button..... (Im trying to make it count when i press the button.)I need to make a listener for the button, and an event that adds 1. (num++)
import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.*; import javax.swing.*; public class ClickIt { public static void Practice()
public void actionPerformed(ActionEvent ae){ float A=0; int a = Integer.parseInt(tf1.getText()); if(ae.getSource()==b2) { A=(((30*a*14) / 100)+(30*a));
I have gotten the code up and running, now I am trying to add a previous button. The next button I have now works fine but I can't seem to get the previous button to work.
I am working on a text based adventure game. (This is NOT OOP at all) The problem comes in at my second if statement inside my loop, it is not adding 1 to my array locations[] it keep printing location[0] then a 1 at the end. Not really sure what is going on here. I would like it to when I type "Go north" it adds 1 to locations[]
E.G locations[0] Go north locations[1] go north locations[2] package com.PenguinGaming; import java.util.Scanner; public class Game{
I'm really struggling adding JLabels to my GUI. The code is giving no errors but the JLables aren't showing up as I think I've done something else wrong. Here's my method for adding the JLabels:
public void showGraphics(){ for(int i=0; i<message.length(); i++){ if(message.charAt(i) == '#'){ JLabel localLabel = new JLabel("test label"); getContentPane().add(localLabel); } } }
I think the problem might be to do with how the rest of the GUI is setup and the fact that I haven't specified where to add the JLabel just that I'm adding them.
The serializable class ImagePanel does not declare a static final serialVersionUID field of type long public class ImagePanel extends JPanel{ ^^^^^^^ ^ ^^2 problems (1 error, 1 warning) mh_sh_highlight_all('java');
im basically just trying to put the image inside the GUI and centre the text underneath it. Which is hard to believe since the text is above the image in the code .
import java.util.Scanner; class Sum { public static void main(String[] args) { int sum = 0; System.out.println("Please write a number, end with ESC button"); Scanner in = new Scanner(System.in);
