The program i am creating consists of two JPanels (currently) and one canvas. The canvas is in the center of the JFrame, while flanked by JPanels where both have 13 buttons each.
To paint a simple picture, my program will draw letters on the middle canvas when a button is clicked.
I created my own buttons that implement the ActionListener interface , so when a button is clicked it will display its character in the console. But my question is, How do you implement the listener to draw something on the Canvas when the button's are clicked?
I want to know how can I make a JPanel slide to to another JPanel (Slowly move to the next). I've made multiple JPanels so when I click on next it will take me to the next panel. Now I just need to add a nice transition to make my program look nicer. Is there an easy way to do it? or any way is fine I just want to add a transition ....
I am tasked with creating several JPanels each of which has a title centered at the top. As such I have created parent panel that each panel extends. However, I am uncertain as to whether drawing the string on the panel or using a JLabel is the best solution. The panels might allow dynamic resizing...
I am working on writing a desktop based email client using swing. First some specifics: I need to show emails in a (dynamically updatable) vertical list. Each item in this vertical list would represent an email showing: (a) the subject, (b) a photo of the sender that I have locally available & a couple of buttons. So, I plan to create a JPanel containing a JLabel to show the Subject, The photo inside a JLabel & JButtons. I have the layout of this panel done and is not a problem.
My problem is with stacking all these JPanels (each representing an email) and showing them on the UI as a list. I am not sure of any way to do this. Moreover, when a new email is received, it has to be displayed at the top of the list (not at the bottom).
Specifically, I need a good way of displaying a vertical list of JPanels & be able to add new JPanels at the top of the list.
i am to add jpanels to an arraylist such that it forms a grid like a 2d array. when i add the first colunm and have to iterate and store the next sequence of jpanels it still stores it in get(0), instead of get(1).
I have two classes involved in this portion. CheckIn_Search
(class #1) is my main UI and I am collecting search information from the user in a jPanel form. When they click "Search" it passes the search criteria to a method that contacts a web service and gets the results. These results are passed to coSearchResults
(class #2) that opens a jFrame and jTable (in modal format, over the main window created by CheckIn_Search.
The user selects a row in the table and that selection data is passed back to coSearchResults to populate a new jPanel form. When the data is passed from coSearchResults, I want to close its window, hide the first jPanel in CheckIn_Search and make the second jPanel visible. To accomplish this, I created a method in CheckIn_Search that simply hides/shows the panels (it will do more later).
I instantiate and call the method in CoSearchResults as part of the button click event. The problem is, it doesn't work. The panels are unaffected and there are no errors. I've put in break-points and it goes into the method.. Here is the coSearch_Results code.
Here is am retrieving the jtable row id and using the first value in the row to get the data from the table model as there is more data than what is displayed in the table. I'm sending that whole row of data to the method that changes visibility.
private void btnOKActionPerformed(java.awt.event.ActionEvent evt) {//GEN-FIRST:event_btnOKActionPerformed // TODO add your handling code here: int rowNum = jTable1.getSelectedRow(); String coNum = jTable1.getValueAt(rowNum,0).toString(); String[] text;
Is it possible to define the same message driven bean as a listener to different queues?
The goal being to define different redelivery configuration for different kind of messages, but handle them all through a single deployment MDB for unity/entity purposes.
The other option is to have many MDBs targeted to the same source code.
I have a problem:I have a simple SWING program with buttons and I can't call "frame2.setVisible(true)" from ActionListener registered on a button. I don't understand, why the listener can't see "frame2".
import javax.swing.*; import java.awt.BorderLayout; import java.awt.GridLayout; import java.awt.event.*; public class test {
I want to make a program that will move a square to the left if you press "a", and to the right if you press "d". (Once I know how to do this I can figure out W and S for up and down by myself). What code would I use for doing that? Here is the program I have now. I used the oracle tutorial but it just shows how to handle for if ANY key is pressed.
This is what I used How to Write a Key Listener (The Java Tutorials > Creating a GUI With JFC/Swing > Writing Event Listeners)
I have a Jbutton in my application named as SUBMIT,on clicking SUBMIT the text of jButton changes to ABORT. I wish to apply enter key listener on both the SUBMIT and ABORT button in my applcation, however I am not able to get the text of the button in key listener,so that i can apply my code based on the current text of Button.
I wanted to create a interface with buttons ofshapes and type of transformation where user first select a shape, the shape will appear and user will have to click on the buttons on resize, reflect, rotate or skew to transform to shape. How can i do the coding? such as adding listeners to the shapes?
I have panel = window(new frame) and its used to render a video image on, i need to pickup a touchscreen press change of event but not sure which event listener to use and on which component. Is it a panel, window or frame event? and which listener would detect a focus change or a mouse press
I know mouse listener and focus listener and window listeners are available but not sure they would be able to detect the screen press on the video rendered image...
Isn't changing my backgrounds in my MouseAdapter I keep getting these errors:
at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source)
I have been working on this mouse movement code that detects which direction the mouse moves in hope to use it in a game. The only problem is that I can not figure out how to make it move to the other side of the screen so I could continue turning to the right or left without having to stop. How would I actually get the x and y coordinants of the mouse to change?
PHP Code: if(x == xscreen){ //set x to 0 }else if(x == 0){ //set x to xscreen }else if(y == yscreen){ //set y to 0 }else if(y == 0){ //set y to yscreen } mh_sh_highlight_all('php');
am trying to create a mouseListener that when you click a tile and drag in any direction it has to collect all the letters in the tiles that were dragged over and save to a stringBuilder. I have everything working its just this last key issue related to mouseDragged that has me stumped. Iv searched countless websites but am still unable to find anything that is remotely close to what i need.
I'm using Eclipse with the Window Builder Pro plugin to create a Java program. I noticed that when I had Eclipse create an action listener for a combobox in a Swing GUI it created an AWT listener.
Did I choose the wrong type of listener? I want my code to use the Swing components because I understand that they are more portable.
1. I am trying to use the getSource method in my inner class, in order to set the JPasswordField within an Inner Listener Class. This is a 4 integer password, setup by my for statement in the loop. I know what I want the program to do, but I don't know the correct language to use. I want the user to press one of the keys (0-9), that value be stored in JPassword (at least I think that is how it works) and for it to display the "*" in the Field---I want this to loop 4x. How do I use the getSource() to do this.
Also, I believe I need to use the set and get methods for the password entered into the JPassField, is that correct? The inner class is not recognizing my the object password that represents the JPasswordField.
2. In my second Inner Listener Class, clearButton, I set the event.getSource method to reset the JPasswordField to " ", when the clear button is pressed. Again, the problem is that the inner class does not recognize password. Why is this the case, since it is still a part of the parent class Atm?
public class Atm extends JFrame { Atm(){ super("ATM"); int i = 0; //Create Panels For ATM JPanel buttonPanel1 = new JPanel(); //To Contain Digits 1-9 buttonPanel1.setLayout(new GridLayout(4, 3));
I have two different classes called Login (in the package View) and RegButtonListener (in the package Controller). I want to use the MVC pattern.
Login creates a GUI for login. I used NetBeans GUI Builder to create it.
In the class RegButtonListener there is the code for the click of the buttons, then various listeners of the GUI.
Now I want to close the login frame at the click of a button so I want to use the dispose() method.
If I had all the code (GUI code and code of the listener) in the same file, close the frame would be easy enough to do because this.dispose(). But in my case I have two different classes.
I also have a second problem.
In Login class (in the packege View) I have included the line :
However, Netbeans tells me an error "package regButton does not exist. <identifier> expected". Why does he consider regButton a package? How can I fix these two problems?
How do I do then?
Below is the code of the two classes.
Login class. public class Login extends javax.swing.JFrame { /** Creates new form Login */ public Login() { initComponents();
I'm running the code below which compiles ok using latest version of Java and on Sublime. The problem when it complies the output screen is blank and I can only see the text by adjusting the size of the box with my mouse - and then it colours in black. Code and screenshot below. Is there something wrong with the paint/graf part of the code?
import java.awt.*; import java.awt.event.*; import javax.swing.*; public class BackArray extends JFrame { int store[] = {2,6,4,8,34,67,19,99,10,12,89,68,45,37}; int xcoord = 100; boolean firsttime=true;
I'm doing a exercise for dragging mouse to draw a line. I found a code to do this, but I don't know something in the code. example array Shape in the code.
I am developing an application where blind person can interact with computer i have completed the part where computer responds as per command given by user.The part where i am stuck is i want to give voice feedback as user moves the curser for example if mouse is on d drive then user should get feedback that its d drive....i want to do it for whole windows ...
my application shows a profile. The profile has various interactors. I'm trying to follow the MVC model, so I neeed to tell my controller that something was selected. But the profile has many elements that can be selected(mostly labels, so not setActionCommand), how do I tell it WHICH one was it?
how do I separate those interactors? I created a HashMap that maps from JLabels to Strings. When a mouse event occurs I loop trough it to search for the event source. If I find it I fire my custom event.
