Capturing global mouse events ?

Is it possible to capture mouse event generated outside the application as well, as if the java app is running and the user opens a explorer and clicks at something, how can i capture that action ?

not with pure Java. JNI with native code

  • Capturing Blocked Mouse Events

    Does anyone know of a way for a displayObject to receive
    mouse events, as the target of that event (MOUSE_OVER, MOUSE_DOWN,
    etc) if it happens to be overlapped by another display object. I've
    tried setting the .mouseEnabled of the obscuring displayObject to
    false, as well as setting its .mouseChildren to false, but no joy
    there. Is there a way for the obscuring displayObject to pass the
    event along to display objects that happen to be beneath it?
    Is there a trick that I don't know of, or is this simply not
    possible?
    -thanks for taking the time to read this post.

  • Handling mouse events anywhere

    Hi,
    We have built an application with a Swing GUI and for automation and testing we would like to record all keyboard and mouse events to be able to play them afterwards.
    The keyboard events can be recorded easily with a KeyboardFocusManager but for the mouse events I still need a solution.
    The GUI consists of a JFrame containing several JPanels. When I add a MouseListener on the JFrame, its mousePressed and mouseReleased events are not called everytime I click somewhere on the frame. For example, when I click on a button inside one of the JPanels, the mouse event methods of the frame are not executed.
    Can somebody tell me how I can easily capture all mouse events in the GUI without adding MouseListeners in every JPanel??
    Thanks in advance...

    I know how to use the Robot class, that's not really the issue.
    What we are doing actually is writing keyboard and mouse events into a file.
    Afterwards we use the Robot class to playback the events in the file. This is no problem, I just don't know how I can easily intercept ALL mouse events in the GUI without adding mouseListeners in each component in the GUI.

  • HTML/JS: Capturing mouse events while Air is out of focus

    Hi,
    I've been trying to determine if it is possible to receive mouse events (like MOUSE_WHEEL) if the Air window does not currently have focus. I'd like my application to support the mouse wheel for scrolling while the cursor is over the application, without requiring the user to click the application and gain focus. My application uses JavaScript to scroll an unordered list within a DIV set to overflow:hidden (to prevent the native scrollbar from appearing).
    Thanks for your help!
    Andrew

    I doubt that AIR would pick up events fired while not having focus. Perhaps you could fake it by creating an AIR project that runs "fullscreen", but has a smaller active window. Anywhere your mouse went it would still capture the scrolling event, but you could conditionalize it so that it only worked in certain areas.

  • Capture All Mouse and Keyboard events even if java window NOT in FOCUS

    Hi All,
    Is this possible to capture all mouse and keyboard events even if java window is not in focus or is minimized. This java program should cature each and every event from the user once the program is started. Any help in this regard is appreciated!
    Thanks&Regards

    I don't think you can. (without JNI)

  • Capturing mouse events from a loaded module.

    I've defined a module and have it to were the mouse
    coordinates (through mouse events) are updating bindable, public
    variables in the module itself.
    In the app parent app (that's loaded the module), i want to
    display the coordinates from the loaded module as it moves around.
    Like I said, I'm close, to where I capture and handle the
    move event in the module itself, I just need to access that info
    from the parent app, etc...
    Any help is appreciated.

    Mouse Events may only be capture INSIDE the java application frame. SO, if your desktop is not a java component, you will not be able to capture the events.
    However, you could maybe use JNI to use native methods so as to get the location of the mouse...

  • Using activex component in openGL app:  mouse event issues.....

    i'm trying to get the Flash ActiveX control to work in an
    OpenGL app. so far i've managed to get the bitmap data and map it
    to a texture succesfully. but i'm having problems getting the mouse
    interaction to work.
    i get an hWnd from IShockWaveFlash's IOleWindow. when i send
    mouse messages to it, the mouse is interpreted correctly by
    actionscript (for example, i have a custom mouse cursor tracking
    _xmouse, _ymouse which works fine).
    however, buttons do not behave correctly. rollover is
    erratic, and only in rare circumstances can i get a button's
    onPress handler to fire.
    am i sending the mouse events in correctly? any ideas of any
    other way to send them in?

  • Mouse event not working on JTable in JAVA 1.4.2

    mouse event is not recognised on empty table when using with java 1.4.2. Please specify if there is any chnge done for mouse event capture for table from java 1.3.1 to java 1.4.2.
    since mouse events are working fine for JTableHeader.
    if anybody have an idea please let me know.

    Hi
    JTable is there on JPanel . same code is working in JAVA 1.3.1
    actually its a bug in java 1.4.2 ( ref. bug_id=4940522 )
    here is the code reference..
    public class TableEditor extends JPanel
    �implements ListSelectionListener, Selector, Editor
    private JTable�myTable;
    private JPopupMenu myPopup;
    private Vector�myActions;
    private Vector�myListeners;
    �
    public TableEditor(String anAssociation, Editor anEditor, int type)
    super(new GridLayout(1,1));
    �
    myListeners = new Vector();
    myActions�= new Vector();
    myPopup�= new JPopupMenu();
    myTable�= new JTable();
    ��
    myTable.getSelectionModel().addListSelectionListener(this);
    myTable.addMouseListener(new MouseAdapter() {
    �public void mouseClicked(MouseEvent me)
    �{
    � if ((me.getModifiers() & MouseEvent.BUTTON3_MASK) != 0)
    � {
    ��// Update actions in case ListSelectionModel are out of sync.
    ��for (int i = 0; i < myActions.size(); i++)
    ��{
    Object o = myActions.elementAt(i);
    if (o instanceof SelectorAction)
    ((SelectorAction)o).check();
    ���}
    myPopup.show(myTable, me.getX(), me.getY());
    �}
    // Added mouse listener to JTableHeader
    // This is a temporary solution to open popup menu on blank table,
    // as in Java 1.4.2 no mouse event captured on blank table.
    // So for now we will capture the event from the table header.
    JTableHeader myTableHeader = myTable.getTableHeader();
    myTableHeader.addMouseListener(new MouseAdapter() {
    public void mouseClicked(MouseEvent me)
    �{
    if ((me.getModifiers() & MouseEvent.BUTTON3_MASK) != 0)
    // Update actions in case ListSelectionModel are out of sync.
    for (int i = 0; i < myActions.size(); i++)
    ��{
    Object o = myActions.elementAt(i);
    if (o instanceof SelectorAction)
    ((SelectorAction)o).check();
    ���}
    myPopup.show(me.getComponent(), me.getX(), me.getY());
    � }
    �});
    The solution given is temporary ( adding JTableHeader component)..
    we want to retain the same functionality .. mouse event should get captured on empty table only..

  • Need More Mouse Events

    [http://forums.sun.com/thread.jspa?messageID=10811388|http://forums.sun.com/thread.jspa?messageID=10811388]
    During search over net I found the above thread and it seems to be describing the same problem which I am also facing. For my application also I need to capture all the mouse events while dragging. I tried the soluiotn mentioned at this thread to solve this problem by overrinding the below method in several ways:
    protected AWTEvent coalesceEvents(AWTEvent existingEvent,AWTEvent newEvent);
    Even after several attempts, I could not succeed. Can you please suggest how to do that. I was not able to reply to above thread so creating this new thread.
    Thanks

    I wanted to see if a timer based approach does indeed produce a smoother curve than just simply listening for mouse drag events. What I came up with below was the resulting test code. Lo and behold, using a timer does indeed produce a smoother curve. But it wasn't because it was capturing more mouse positions, it was because it was capturing less. Ain't that a kicker? Another interesting thing is that according to the source code, coalesceEvents is a no-op. The documentation, however, would have you believe that it coalesces mouse events as I thought it did.
