I read the oracle doc example, i understand the concept but still nothing is happening on show,first ,next method of CardLayout in ActionPerformed. Code is highlighted where I am facing problem.
I am writing a ComputerBaseTest application with Netbeans. I have each question on a panel and I want the questions(panels) to be switched, viewing the previous and the next question on a single frame, but I do not know how.
I only understand frame switching if each questn is to be on a frame but each score on each question (frame) do not sum up to give the overall score at the end of the test. Using multi-frame shows a sign of bad programming.
I'm making a game of checkers for my A2 Computing coursework which is due in within a week. I have completely finished the game, and only thing I have left to do is connect the two JPanels together via a CardLayout that I have made. However I am unsure how to do so
I have kept the code I am displaying to a minimal, hence I have removed all the action listeners for my buttons, anyway the problem I have is that, I would like it so that when the user clicks on the 'Multiplayer' button which is the array button ourButtons[1], it will then transition into my main game screen so that the user can then play a game of checkers.
Here is the main important GUI from my CheckerBoard class:
import java.awt.*; import java.awt.event.*; import javax.swing.*; public class CheckerBoard extends JPanel implements ActionListener, MouseListener { // Main routine that opens an Applet that shows a CheckerBoard public static void main(String[] args) { new CLayout();
I have buttons created on a frame and then I register the listener from a controller in a controller-view relationship.
When I click the button on the face, the action never executes for some reason. I thought maybe there was a problem registering the listener but I can call the buttons doclick() method and it executes as it should. Perhaps I'm overlooking something really obvious here but I can't see it.
again, when i click the button nothing happens. but if i add the following code
btnEight.doclick()
the actionPerformed invokes in theController as I intended.
You can see the entire project on GitHub so you can see the full context. The controller class contains the listener and the view class contains the buttons.
I've recently decided to learn Java on my own using internet material such as forums, blogs and you tube. Ive never programed before but through some research I concluded that Java is going to be on the mid spectrum of difficulty as far as verbiage goes. I ma in no way implying that Java is easy but instead closer to spoken English that c++ if my research is correct. So here is my attempt at a basic program where I click a button and it will make an image appear. Not sure where Im falling short
package clicktoimage; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Clicktoimage extends JFrame { private JLabel label; private ImageIcon image;
Projectsrccom.mypackageMyClass.java resourcesicon.pngmyexe.exe Right now I have to run the exe like this : - It has hardcoded the path of the exe :command = "cmd /c start /b cmd.exe /K "cd " + outputFolderPath + " && C:myfoldermyexe.exe " + "param1=value1 param2=value2 " ;
Process p = Runtime.getRuntime().exec(command); This works fine. But, When I package it as a jar I want to give a relative path to my resources folder. How can I make this happen?
I tried:File f = new File("resources/myexe.exe"); String path = f.getAbsolutePath(); but this "path" did not work.
Another way would be to extract the exe to a local path on the server, but there is a possibility that I could face permission issues.
I want to switch panel on click of a button and code for switching panels is written in update method (Which gets called from notify observer of another class as part of Observer pattern.
playGame in Panel 1 of class 1 calls another class (class 2)and data comes in update method of class 1(Observer interface).
Now for switching panels code is in gameControllerDataProcessing . I am not able to switch the panels when this functionality runs.
However if i dont call the unoGameController.playGame(playerFirst.getText(), playerSecond.getText() and directly call the update method or directly write the switching panel code . then it works fine.
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.
When i click on the button from bottom panel, top panel need to be redrawn. But redrawing is not happening. It happens only when resizing the applet.
public class Graphics_Chart(){ public init(){ JScrollPane topPane = new JScrollPane(new ImagePanel2()); topPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER); topPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_NEVER);
I am developing a game where a player has to find a path in a maze. Right now the player can only click the buttons on the maze. I need an option to use the arrow keys.
I have picked up pieces from my code to illustrate my problem. Below is the code. If I call "AnyClass" in the "AppletClass" it works but when I call "MiddleClass" in the "AppletClass" and MiddleClass" calls "AnyClass" it does not work. In my project at www.hiredforoneday.com I call 4 panels in CardLayout before I call "AnyClass" which is the "Maze"
I have a stage,it has two layers scene, if user click the button,then change to another layer, and also can change back. It just like swing cardlayout. How can i implement cardlayout in JAVAFX?
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;
I wrote the following code to get a frame,button in south and a red color circle,which i got.In the "actionPerformed" method i wrote "setContentPane(mp2)" thinking it would put another panel on the frame with a blue circle but when i pushed the button,the button got stuck and the circled did not change.
import java.io.*; import javax.swing.*; import java.awt.*; import java.awt.event.*; class Fra implements ActionListener { MyPanel2 mp2; JFrame frame; JButton button; public static void main(String[] args)
The question is when I hit the maximize button on the JFrame my panel instantly goes to the top left corner of the JFrame. Is it possible to center the panel inside the JFrame, when the maximize button is pushed? I am familiar with push and grow that MigLayout uses but this isn't exactly what I need. I don't want several textFields to span the screen. Instead I would rather have the panel centered.
This is just a sample project to test out the MigLayout API
Is it good practice to create a inner class for layered panels with lots of components? In my opinion this makes the code easier to read and a lot less clustered.
one of the java swing challenge I am facing. Problem statement: there are two JPanels panel 1 and panel 2 placed on a JFrame one below the other as panel 2 below panel 1. Now, I need to put a JButton in any one of the panels such that this JButton displays half in panel 1 and half in panel 2.
I'm having trouble with this program. In my textbook it says "Write an application that displays a frame containing two panels. Each panel should contain two images (use four unique images - your choice). Fix the size of the first panel so that both of its images remain side by side. Allow the other panel to change size as needed. Experiment with the size of the window to see the images change orientation. Make sure you understand why the application behaves as it does". I successfully imported the images, but I can't find out anywhere how to allow the second panel to change size with the window.
import java.awt.*; import javax.swing.*; public class TwoPanels { public static void main(String[] args) { JFrame frame = new JFrame ("Embedded Images"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); ImageIcon iconOne = new ImageIcon ("glove.jpg"); ImageIcon iconTwo = new ImageIcon ("cleats.jpg"); ImageIcon iconThr = new ImageIcon ("bat.jpg"); ImageIcon iconFou = new ImageIcon ("baseball.jpg");
i have two classes, one is a GUI program and the other is an index writer program. the GUI program uses a j file chooser to select directories and display them in the text fields.the index writer is supposed to take the directories in the text fields and read from one(document location) and write into the other(index location) i want to run the index writer program by the click of a button(indexfbuton) in the gui programi have been able to get the directories to display in the text field but when i click the button to run the index writer class, nothing happens..here is the GUI class
I have been trying to develop a small desktop application. I have JFrame and a button. When I click the button, the app is supposed to save record to database. But it is impossible to click the botton twice. To explain in detail: when a user fill in the form and click the button, the app will warn the user if he/she haven't fill in the appropriate JTextFields. After warning it is impossible to click the button again. I mean after first click, the button is busy and impossible to click.
I am working on web project in java. i have taken buttons in column..and projects is my column..when i click on a button in first row ,i want fetch all information about selected project....so how can i do that?
I have a textbox called "answer" and 10 different buttons on a form. Now what i would like to do is click the button and have the Button Text in the textbox with the already present text.
So if i click the button 1 it should automatically recognize the clicked button and have its text copied to textbox.
I know the '.get' method but lets say i have 100 buttons so i cant repeat it for every single one of them.
I'm using java FX-8 and JDK 1.8,Netbeans 8.0.2.I want to open pdf on button click in my JavaFXML Application.I have triued pdf viewer plugins and iText but it doesn;t work.I have to pass variable value in pdf too.
