Unhide mouse cursor

Hi!
I know how to hide the mouse cursor in Swing with the createCustomCursor() method. But, how can I unhide it after ?
Thanks in advance

setCursor(new Cursor(Cursor.DEFAULT_CURSOR));?

How to change the cursor type when a TableView class was added to a Swing application?

We can resize column width by dragging the column divider in the table header. This is a built-in feature of the TableView class.
Normally, the cursor will become to east-resize (or west-resize) type with positioning the cursor just to the right of a column header.
However, I found that the cursor is remaining the default type at the same position if I integrate JavaFX into Swing Application. That is adding the TableView to a Scene, and then adding this Scene to a JFXPanel, finally, adding this JFXPanel to the JFrame.
The sample codes are listing below:
public class Run extends JFrame {
    Run() {
        setSize(600, 450);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        initComponents();
    private void initComponents() {
        final JFXPanel fxPanel = new JFXPanel();
        this.getContentPane().add(fxPanel);
        Platform.runLater(new Runnable() {
            @Override
            public void run() {
                initFX(fxPanel);
    private void initFX(JFXPanel fxPanel) {
        Scene scene = null;
        try {
            scene = FXMLLoader.load(
                new File("res/fxml_example.fxml").toURI().toURL()
        } catch (Exception ex) {
            ex.printStackTrace();
        fxPanel.setScene(scene);
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                new Run().setVisible(true);
fxml_example.fxml:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.Scene?>
<?import javafx.scene.control.TableView?>
<?import javafx.scene.control.TableColumn?>
<Scene xmlns:fx="http://javafx.com/fxml">
    <TableView fx:id="tableView"
               editable="true">
        <columns>
            <TableColumn text="COL1">
            </TableColumn>
            <TableColumn text="COL2">
            </TableColumn>
            <TableColumn text="COL3">
            </TableColumn>
            <TableColumn text="COL4">
            </TableColumn>
            <TableColumn text="COL5">
            </TableColumn>
        </columns>
    </TableView>
</Scene>
So, are there anyone can advise how to fix these codes; make the cursor can change to east-resize (or west-resize) type when this TableView class was added to a Swing application?

Thanks for the report. I've just filed a JIRA issue: https://javafx-jira.kenai.com/browse/RT-34009

How to set cursor in the beginning of a test in a JTextField in Java Swings

hi
I am new to Swing.I have to display a large text in a text field.Whenever I am displaying it is showing the tale of the text.To see the beginning of the text I have to move the cursor using keys.How can I set the cursor in the beginning of the text or how can I display the text with its beginning characters.

You're practically there...
You usually put all the jars in the same directory and then specify the class-path attribute in your manifest:
Class-Path: other.jarYou can of course specify a relative path to another jar:
Class-Path: lib/other.jarBut that's up to you how you want to package these things.
I don't think that jars in jars are permitted.
Hope this helps.

How to set cursor to text field from message box in swing

I am working Text Field validations in a swing application. when incorrect information is entred in text field a Message is displayed. When I click on OK button on message box I want to set the cursor position to that particular text field for which thet message is displayed.

theOffendingTextfield.requestFocusInWindow();may need to be wrapped in a Swingutilities.invokeLater,
and if you want the text highlighted (so you can just type in new text)
theOffendingTextfield.requestFocusInWindow();
theOffendingTextfield.selectAll();

Problem with JFrame and busy/wait Cursor

Hi -- I'm trying to set a JFrame's cursor to be the busy cursor,
for the duration of some operation (usually just a few seconds).
I can get it to work in some situations, but not others.
Timing does seem to be an issue.
There are thousands of posts on the BugParade, but
in general Sun indicates this is not a bug. I just need
a work-around.
I've written a test program below to demonstrate the problem.
I have the problem on Solaris, running with both J2SE 1.3 and 1.4.
I have not tested on Windows yet.
When you run the following code, three JFrames will be opened,
each with the same 5 buttons. The first "F1" listens to its own
buttons, and works fine. The other two (F2 and F3) listen
to each other's buttons.
The "BUSY" button simply sets the cursor on its listener
to the busy cursor. The "DONE" button sets it to the
default cursor. These work fine.
The "SLEEP" button sets the cursor, sleeps for 3 seconds,
and sets it back. This does not work.
The "INVOKE LATER" button does the same thing,
except is uses invokeLater to sleep and set the
cursor back. This also does not work.
The "DELAY" button sleeps for 3 seconds (giving you
time to move the mouse into the other (listerner's)
window, and then it behaves just like the "SLEEP"
button. This works.
Any ideas would be appreciated, thanks.

I've had the same problems with cursors and repaints in a swing application, and I was thinking of if I could use invokeLater, but I never got that far with it.
I still believe you would need a thread for the time consuming task, and that invokeLater is something you only need to use in a thread different from the event thread.

Problem On Windows-XP of Swing App

The problem of the Heavy-weight Swing appication in the following Operating environment -
Operating System : Microsoft Windows XP [Version 5.1.2600]
Processor : Intel Pentium-4 2.20 GHz
RAM : 256 MB
Graphics Adapter : RADEON IGP 340M / Intel 82845
Java Runtime Environment -( java.exe )
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)
Problem -
It takes more than 25 minutes to load. After loading it shows the white screen.
As we move the cursor over the screen the GUI components under the cursor are displayed.
When the user interacts with the application e.g. by clicking the button.
again more than 1 minute is spent the OS in the response
At the startup , program constructs 13 objects. Each object is one JPanel.
Each JPanel again contain one JTabbadPane containing 5 tabs.
Each tab contain 2-3 Jpanels.
In these JPanels there are lots of Swing GUI components.
For each constructor of the object 1-2 minutes are required.
Overall time to load the complete program is 25 minutes.
During these 25 minutes CPU usage is 100 %
All other activities are stopped
The Solutions we have tried.
1. downloaded the latest JRE 1.4
2. used various JVM options ( command line arguments to java.exe )
-Xmx -Xms
-XX:+AggressiveHeap
-Dsun.java2d.3d=false
-Dsun.java2d.ddoffscreen=false
-Dsun.java2d.noddraw=true
2. created the executable jar file
3. analyzed and compared the System properties, Graphics Environment properties
for Windows 98 and Windows -XP
4. downloaded the latest update for windows-xp's driver and
MS JVM( java virtual machine)
5. tried the jre.exe 's options
6. sets various options of UIManager
On Windows 98 SE it takes less than 9 seconds to load that program.

Hi,
On the Windows XP machine, are you running a virus checker,
(like Sophos?), that tries to verify the runtime jar files and
each class file as it's loaded?

Setting Cursor - For a window and application wide

Hi,
Can somebody please help with a cursor problem ? I am not able to set the busy cursor for a frame when the application is doing some work. I have tried many methods of doing this (some of them from these forums...) but still I am not able to make this work.
1) setting the cursor before doing the work and resetting after the
work doesnt work.
2) setting the cursor for the window by calling
Window window = SwingUtilities.windowForComponent(getRootPane().getGlassPane());
window.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
This works but the events are not blocked by the frame i.e if i
click on any part of the window like a button or something, that
event is fired after the work is done. So this is not good.
3) created a glass pane for the window and blocked all the events. Then
set the cursor for the the glass pane. This does not work either
since the event thread is doing the work. So had to create another
thread to do the work. This works but when the cursor is reset back,
it doesnt reset. I have to move the mouse a bit to reset it. So this
is not good either.
4) created a work around for the cursor by creating a modal dialog box
saying "Processing..." in the event thread and doing the work in the
worker thread. The worker thread posts an event to dispose the
dialog box after the work is done. This works perfectly though it is
still not good because the cursor is not showing busy. Because of
the modal dialog box, the user cant do anything in the application
which is exactly what i want. Is this ok ? Can somebody provide any
other work around for this ?
5) Also I have another question for you guys. In the worker thread if i
do something like updating the gui etc., it takes a lot of time
almost 10 times more than when the work is done in a single threaded
environment. Is this because of the communication between the worker
thread and the event thread ? If I do only data related work not gui
work in the worker thread, this is fine.
I am new to Swing, so somebody please explain to me if they can.
My environment is JDK 1.1.7, Swing 1.1 on Sun Solaris 2.5.1. Is this because I am using old versions. Is this resolved in the newer versions like 1.3 etc ?

That is all true. The problem is the need to give a user the ability to run a program that has secrets that should only be visible by root. If you give the user ownership, they cab see the keys to the kingdom.
For example, you may want to allow a user to connect to an arbitrary wireless access point. Generally, this is a privileged operation -- you want to give them permission to do it, but don't want to give them ownership. You may also not want them to be able to see or modify the pass phrases.

Using the swing clipboard and DefaultEditorKit.copytAction

Hi all
Ive heard that i can use the swing DefaultEditorKit to basically copy and paste text throughout my application (like using Ctrl+C ctrl+V)
basically i have a number of elements such as textpanes and edit boxes and i want to be able to copy and paste text between them with the least amount of effort, most examples i have seen about implementing copy and paste require you to specify the elements that you need to copy and paste from
i dont want to have to specify every element, i just want a simple action that says copy the selected text, and paste the selected text (dont have to worry about cut really)
Ctrl+C and Ctrl+V both do this natrually, but how do i call a simple method that does the same thing that the keystrokes do.
I just want two menu items that when i invoke their click listeenrs to say something like
copylistener{
copy();
Ive seen a few examples of the swing methods but these also seem to need to invoke actions on the elements that you want to copy and paste between, but the keystroke dont need any of this

Sorry, I see your confusion now.
Yes, you need a few helper methods to get the actual Action, but you don't need to do this for every text component because the Action is shared by all text components.
Text components use an EditorKit. The editor kit provides support for basic functionality of each text component. (ie. cursor movement, text selection, cut, copy, paste...). The EditorKit uses Actions to implement the basic support. Each Action extends TextAction which contains a method "getFocusedComponent" which returns the last text component that currently has focus. (clicking on a menu item is only a temporary loss of focus).
So the code in the TextComponentDemo is being very efficient and is reusing the static Action that was created by the DefaultEditorKit. So even though your form may have multiple text components, you only need to create your menu item once using any text component.
If you don't want your code to reuse the existing Actions, you can create your own Action directly from the EditorKit. Then this Action can be used to create a JMenuItem or JButton. Here is a simple example of using this approach:

How to set the cursor to one point (x0, y0)

Hello
I work with swing and I have done a GUI.
In the GUI, I have some points. When I approach one point (x0, y0), I would like to set the cursor of the mouse to the exact position (x0, y0). But I can't find the class that can set the position of the cursor.
Could anyone help me, thanks.

Have a look at Robot-class, there's a method mouseMove.
Hope that helps.

Keynote 5.0 presentation dual display mode: no cursor on audience display

In KN 5.0 presentation dual mode, the cursor only shows on the presenter's screen, not the audience screen in auditorium. I've tried all the combinations in Keynote Preferences, and hitting the C key doesn't help. No clues in the KN 5.0 manual. I'm using DVI to VGA dongle -- could it be a VGA limitation? Or perhaps a secret switch or keystroke combo?

are you swinging the cursor over onto the projector screen, or assuming it works like PPT where you move your mouse on the proxy image on the presenter screen and it shows up on the projector?
