I'm trying to right a GUI in swing, and as part of my program, I want to open a secondary window out of the main window when a mouse clicks on the main window. Then, once I click a button on the secondary window, I want that window to close and submit data to the main window (like an info form). I have almost figured out how to do this, except for one problem. By putting a variable inside my form window called "ready," and then in my main window running a loop that constantly checks if ready is true and doesn't proceed until its true, I can create the form window, modify the values in it (currently just one value called "difficulty" that's modified by a jSlider), and then when i click the "begin" button, ready is changed to true, the form window closes, and the main window can proceed. However, when I try to put the while loop checking the ready variable inside a mouseClicked method in the main window, the form window freezes when it opens, and you can't see any of its content or modify it in any way (you can't even close it).
Here is my code:
//form window class import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.event.*; public class formWindow extends JFrame { private JTextField instructions1;
I have a JTable that is within a JScrollPane. If I try to write add a MouseListener to the JTable it never fires. However, a mouse event does fire for the JScrollPane which it is added to. Is there a way to prevent the JScrollPane from capturing the event or passing it along to the JTable?
Just run the following code and move the mouse next to the text of the button and you will see exactly what I am talking about. Any way to prevent this continuous flash?
import java.awt.Dimension; import javax.swing.JButton; public class GUI { public static void main (String[] args) { javax.swing.JFrame frame = new javax.swing.JFrame(); javax.swing.JPanel panel = new javax.swing.JPanel();
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;
treeView.setOnMouseClicked(new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent mouseEvent) { if (mouseEvent.getClickCount() == 2 && mouseEvent.getButton() == MouseButton.PRIMARY) { // Some action } } });
For some reason when I click on a tab body I can also perform the listener action. How I can add additional statement to perform the action only if I select node?
In my code where the Button Action Performed is created, I have done the following to ensure that the visibility of the JTable and JScrollPane have been set to true. But it does not work?
I develop a desktop soft use javafx8, and remove default border (e.g. title and close/min/max button), now use mouse left key click the taskbar icon is nothing,i want click the taskbar icon,if stage it's show then hidden, if stage it's hidden then show it,the problem is I can't capture any mouse click event,so i can't show or hidden my stage.
i want to make adding into mysql database and then when i click adds, jtable show those data automatically. but it seem to get error at display part, it shows " Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: Uncompilable source code - illegal start of expression" and jtable do not show the added data but in mysql, data is properly kept.
private void jtPropertyChange(java.beans.PropertyChangeEvent evt) { DefaultTableModel model = (DefaultTableModel) jt.getModel(); try { Class.forName("com.mysql.jdbc.Driver"); con = DriverManager.getConnection(url, user, password); String sql = "SELECT * FROM `companya`";
I have a JFrame with a button called "Start". The code behind the "Start" button triggers a function (startwork() ) that traverses through log files and then inserts rows into my JTable. If I call the startwork() function from the Start button action performed event, then when it inserts the rows to the JTable it is not immediately shown...
The code has to finish before the JTable is refreshed. However, if I run the startwork() function as soon as the JFrame is displayed (from the main() function) then I can see the Jtable being populated dynamically as it is inserting the rows.
How to allow the user to click on the START button and yet behave correctly to where the JTable is updated properly so that I can see the rows being inserted as it progresses.
I want to use this class and method with all of my buttons and text fields. My program contains 1 push button that adds questions and answers to a test, 2nd button that starts a test, a 3rd button that scores the test, and a text field that enters the user information. How would this work? I know how to create questions and answers, start a test, and score a test it's just a matter of how to implement the button and text fields. I'll post the code that I have done so far.
See:
private class ButtonListener implements ActionListener{ public void actionPerformed (ActionEvent event)
with all of my buttons and text fields.
import javax.swing.JFrame; public class TestingDriver { //----------------------------------------------------------------- // Creates and displays the main program frame. //----------------------------------------------------------------- public static void main (String[] args) { JFrame frame = new JFrame ("Testing Program"); frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
My programms is working perfectly except for one little detail that annoys me. I have a JTable with a button on the first column that allows to delete this row from the table. Its working well except when I try to delete the last row of the table, the button stay there and then the table freeze and i can't delete any rows because i receive a "Out of bound Exception" . But, when I use the command table.getRowCount());
Before and after the removal of the line, the table "knows" that a line was removed but as i said, the button stay there. The screenshots in thumbnails show the situation before and after clicking the button next to the "Year" cell.
It's good to add that i'm adding rows in the table from a button outside the table.
Heres my code:
Main.java
static String [] title = {"X","Nom","SRM","Rend.","%","Kg",}; static Object[][] contenu; static DefaultTableModel model1 = new DefaultTableModel(contenu, title); static JTable tableauGrains = new JTable(model1); tableauGrains.getColumn("X").setCellRenderer(new ButtonRenderer()); tableauGrains.getColumn("X").setCellEditor(new ButtonEditor(new JCheckBox())); ButtonRenderer.java
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 have my paint application, i use the following mouse event to draw my shapes (mousePressed, mouseReleased, mouseDragged). Now after the user paint a circle for example, he must be able to drag the shape; to be able to do this. i think i must again implement the different mouse Events. I have done it and the drag is not working. How can i achieve this. can we implement multiple (mousePressed, mouseReleased, mouseDragged) in the same java class??
I've got the game working just fine, but I don't like the way it starts playing the second you hit the "Run Last Class" button in Eclipse, and would really like to have the game start, then wait for the user to click a button before running the core WHILE loop. Everything is implemented in a single class, and here is the playGame method that starts the ball moving:
private void playGame(){ while (!gameover){ moveBall(); checkForCollisions(); }
All I want to do is pause before the WHILE loop until the users clicks the mouse button, nothing fancier than that! I've done quite a bit of reading, and it looks like ActionEvent may be the way to go, but I'm not clear on how to use it correctly in this scenario.
java.awt.Component is an abstract class, and it's direct Sub-classes are Button, Canvas, Checkbox, Choice, Container, Label, List, Scrollbar, Text Component
So, when I use addXListener(mylistenerclass m);//which is a method of Component class which object is holding the list of all listeners, for a particular Event Source?
I am under the assumption that - there is an Event Source Object(possibly static) for every Event Source type(mouse, keyboard etc) that holds a list of destinations(classes that implements their listener interface) - added to the the object via addXListener method. When an event happens(mouse click, drag etc) the Event Source Object creates an Event Object and send it to all the destinations. Is my assumption correct? I can't seem to find the location or declaration of Event Source Object and the list where it stores it's registered destinations.
I think will be easy for me start with a GUI and then make things happens when the user clic on Buttons.Is there a good book about Event driven development on Java?
So for a test i have a small array set as a jlist which is the contents of my jscrollpane, and it appears as if nothing is there until i adjust the window size by dragging it out or in... whats going on?
In the method mouseClicked(MouseEvent me) the co-ords of the click are obtained.
* if they are within the confines of the rectangle rect, console output System.out.println("inside box") is displayed * in either case the click co-ords are displayed in the console
I'm getting the co-ords of the mouse clicks but no message when the click is inside the box
import java.awt.*; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; /* Experiment 04 was successful. So now (Experiment 05) I must try and see if I can identify mouse clicks that occur within the rectangle. */
public class AFrame extends Frame implements MouseListener { ARectangle rect; public AFrame(ARectangle rect) {
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();
