Global Event Handling

I am writing a program that needs to detect keystrokes and mouseclicks globally. Right now I am using KeyListener and MouseListener to keep track of all keystrokes and mouseclicks, but that only handles keystrokes and mouseclicks in the window of my application. How can I detect global keystrokes and mouseclicks? I want to be able to open another Windows application (say Notepad) and have my application detect all the keystrokes occuring within that application.
Thanks

You will need to research native methods in order to do this. Essentially you will have to have the OS inform your application of these events.

Global event handler for preinitialize

Is there anyway to add a global event handler on the
components preinitialize event?
What I need to do is to be able to enable / disable, and show
/ hide component dynamically based on a access list. My plan was to
have a global event handler that listens to the preinitialize
event, at that time, checks if the user has access to the component
or not. If not, I'll disable / hide the component.
What I did so far is:
in my main app.mxml file, I have:
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
preinitialize="preinit(event)"
so the preinit() function is invoked on the app's
preinitialize event.
Then I have the preinit() function (see attached code below).
However, it does work as there is no trace message printed.
I changed to use KeyBoardEvent.KEY_DOWN and that seems
working when I press any key.
I also tried to use the app.stage.addEventListener() but the
stage object is null in the preinitialize event.
Thanks in advance for your help.

Thank you for follow up on my question.
I do know these two properties. But that does not solve the
problem. Let me explain it with an example.
That's say, when the user logs in, I loads the access list.
Then the app displays a panel with some form entries. If I am able
to register a global event listener for the component
initialization events, I can check the permission and optionally
hide some components. Otherwise, I would need to programmatically
travels my component tree to evaluate each component individually
to set there visible/includeInLayout properties, which is error
prone.
The problem is that the component is visible to one user but
would be hidden to another, so it can not be set at the design
time.
The approach I am using right now is to extend the default
components to add an event listener. But I'd like to know if it is
possible to register a global event listener to be notified when
any component is created. As my first post says, I tried to use the
systemManager and listen to the PREINITIALIZE event, but that
didn't get always get invoked.

Hello Reema
The following sample report shows how to handle event in principle (see the § marks)..
The following sample report show customer data ("Header"; KNB1) in the first ALV list and sales areas ("Detail"; KNVV) for the selected customer (event double-click) in the second ALV list.

WPF UI running in seperate runspace - able to set/get controls via synchronized hash table, but referencing the control via the hash table from within an event handler causes both runspaces to hang.

I am trying to build a proof of concept where a WPF form is hosted in a seperate runspace and updates are handled from the primary shell/runspace. I have had some success thanks to a great article by Boe Prox, but I am having an issue I wanted to open up
to see if anyone had a suggestion.
My goals are as follows:
1.) Set control properties from the primary runspace (Completed)
2.) Get control properties from the primary runspace (Completed)
3.) Respond to WPF form events in the UI runspace from the primary runspace (Kind of broken).
I have the ability to read/write values to the form, but I am having difficulty with events. Specifically, I can fire and handle events, but the minute I try to reference the $SyncHash from within the event it appears to cause a blocking condition hanging both
runspaces. As a result, I am unable to update the form based on an event being fired by a control.
In the example below, the form is loaded and the following steps occur:
1.) Update-Combobox is called and it populates the combobox with a list of service names and selects the first item.
2.) update-textbox is called and sets the Text property of the textbox.
3.) The Text value of the textbox is read by the function read-textbox and output using write-host.
4.) An event handle is registered for the SelectionChanged event for the combobox to call the update-textbox function used earlier.
5.) If you change the selection on the combobox, the shell and UI hangs as soon as $SyncHash is referenced. I suspect this is causing some sort of blocking condition from multiple threads trying to access the synchronized nature of the hash table, but I am
unsure as to why / how to work around it. If you comment out the line "$SyncHash.TXT_Output.Dispatcher.Invoke("Send",[action]{$SyncHash.TXT_Output.Text = $Value})" within update-textbox the event handler will execute/complete.

Thanks again for the responses. This may not be possible, but I thought I would throw it out there. I appreciate your help in looking into this.
To clarify the "Respond to control events in the main runspace"... I'm would like to have an event generated by a form object in the UI runspace (ex: combo box selectionchanged event) trigger a delegate within the main runspace and have that delegate in
the main runspace update the form in the UI runspace.
ex:
1.) User changes selection on combo box generating form event
2.) Event calls delegate (which I have gotten to work)
3.) Delegate does some basic processing (works)
4.) Delegate attempts to update form in UI runspace (hangs)
As to the delegates / which runspace they are running in. I see the $synchash variable if I run get-var within a delegate, but I do not see the $Form variable so I am assuming that they are in the main runspace. Do you agree with that assumption?

Uncaught error handler (global error handling) not working in Chrome FP 10.1.103.22

A few days ago I very happily discovered the new global error handling available in flash-player (FP) 10.1
Now while all works well in Firefox (using Adobe's FP 10.1.102.64), nothing happens in Chrome (using Google's FP 10.1.103.22).
I can disable Google's FP using the "about:plugins" page in Chrome, restart the browser, and then everything works since the browser falls back to the other flash plugin installed, which is again Adobe's FP 10.1.102.64.
Is this a known bug?

Don't tell me the uncaught error handler only works for a debugger version....??
The documentation, which I read quite carefully, doesn't have a word on this. It suggests rather the opposite:
"When content is running in a debugger version of the runtime, such as the debugger version of Flash Player or the AIR Debug Launcher (ADL), an uncaught error dialog appears when an uncaught error happens. For those runtime versions, the error dialog appears even when a listener is registered for the uncaughtError event. To prevent the dialog from appearing in that situation, call the UncaughtErrorEvent object's preventDefault() method."

Global Error Handling - Possible?

Hi there!
Does anyone know if it's possible to catch unhandled errors
that occur in a flex application globally?
The Application.error event allows you to capture Error
Events that arise when communication with the outside world fails
for one reason or another, but as much as I've googled I haven't
been able to find anything for capturing coding errors such as
nullpointers etc. at runtime without wrapping every single line of
code with a try-catch.
In an ideal world I would like to catch these errors and
report them for logging on the server. Has anyone managed to
achieve this without resorting to try-catch-spamming?
The Flex-application in question is a central part of an
e-commerse system so it's rather silly that live errors remain
largely untracked...
Your thoughts would be highly appreciated!

Hi,
Try referring the below links...
http://www.summa-tech.com/blog/2010/01/04/global-error-handling-in-flex/
http://livedocs.adobe.com/flex/3/html/help.html?content=11_Handling_errors_06.html
You have one sample demo with source in first link.
Hope this will be helpful.
If this post answers your question or helps, please kindly mark it as such.

Javascript error in event handler! Event Type = element [edge.2.0.0.min.js:162]

I'm doing a little edge project (now in beta version) for my girlfriend (she hates the code), with examples of the animate() method and other functions like setInteval(), but when I run I get the following error in Chrome console:
Javascript error in event handler! Event Type = element [edge.2.0.0.min.js:162]
But this library is global for all projects, how is possible that trigger an error?
Example here:
https://app.box.com/s/m7nof4al6597gfn47jlu
Thanks.

you dont need to import java ease !!
it's already included in edge animate, remove that yepnope completely your problem will gone

Swing locks up during event handling of a simple button... bug or feature?

I have the following code:
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JToolBar;
import javax.swing.SwingUtilities;
public class Test extends JFrame {
     private static final long serialVersionUID = 1L;
     private JButton button;
     public static void main(String[] args)
          SwingUtilities.invokeLater(new Runnable(){public void run(){new Test();}});
     public Test()
          setSize(200,00);
          setLayout(new BorderLayout());
          JToolBar toolbar = new JToolBar();
          button = new JButton("button");
          button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { button.setEnabled(false);}});
          toolbar.add(button);
          getContentPane().add(toolbar, BorderLayout.SOUTH);
          JPanel panel = new JPanel();
          panel.setPreferredSize(new Dimension(200,10000));
          for(int i=0;i<10000; i++) { panel.add(new JLabel(""+(Math.random()*1000))); }
          JScrollPane scrollpane = new JScrollPane();
          scrollpane.getViewport().add(panel);
          scrollpane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
          scrollpane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
          scrollpane.setPreferredSize(getSize());
          scrollpane.setSize(getSize());
          getContentPane().add(scrollpane, BorderLayout.CENTER);
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          setLocationRelativeTo(null);
          setVisible(true);
          pack();
}This code is lethal to swing: when pressing the button, for no identifiable reason the entire UI will lock up, even though all the event handler is doing is setting the button's "enabled" property to false. The more content is located in the panel, the longer this locking takes (set -Xmx1024M and the label loop to 1000000 items, then enjoy timing how long it takes swing to realise that all it has to do is disable the button...)
Does anyone here know of how to bypass this behaviour (and if so, how?), or is it something disastrous that cannot be coded around because it's inherent Swing behaviour?
I tried putting the setEnabled(false) call in a WorkerThread... that does nothing. It feels very much like somehow all components are locked, while the entire UI is revalidated, but timing revalidation shows that the panel revalidates in less than 50ms, after which Swing's stalled for no reason that I can identify.
Bug? Feature?
how do I make it stop doing this =(
- Mike

However, if you replace "setEnabled(false)" with "setForeground(Color.red)") the change is instant,I added a second button to the toolbar and invoked setEnabled(true) on the first button and the change is instant as well. I was just looking at the Component code to see the difference between the two. There are a couple of differences:
    public void setEnabled(boolean b) {
        enable(b);
     * @deprecated As of JDK version 1.1,
     * replaced by <code>setEnabled(boolean)</code>.
    @Deprecated
    public void enable() {
        if (!enabled) {
            synchronized (getTreeLock()) {
                enabled = true;
                ComponentPeer peer = this.peer;
                if (peer != null) {
                    peer.enable();
                    if (visible) {
                        updateCursorImmediately();
            if (accessibleContext != null) {
                accessibleContext.firePropertyChange(
                    AccessibleContext.ACCESSIBLE_STATE_PROPERTY,
                    null, AccessibleState.ENABLED);
     * @deprecated As of JDK version 1.1,
     * replaced by <code>setEnabled(boolean)</code>.
    @Deprecated
    public void enable(boolean b) {
        if (b) {
            enable();
        } else {
            disable();
     * @deprecated As of JDK version 1.1,
     * replaced by <code>setEnabled(boolean)</code>.
    @Deprecated
    public void disable() {
        if (enabled) {
            KeyboardFocusManager.clearMostRecentFocusOwner(this);
            synchronized (getTreeLock()) {
                enabled = false;
                if (isFocusOwner()) {
                    // Don't clear the global focus owner. If transferFocus
                    // fails, we want the focus to stay on the disabled
                    // Component so that keyboard traversal, et. al. still
                    // makes sense to the user.
                    autoTransferFocus(false);
                ComponentPeer peer = this.peer;
                if (peer != null) {
                    peer.disable();
                    if (visible) {
                        updateCursorImmediately();
            if (accessibleContext != null) {
                accessibleContext.firePropertyChange(
                    AccessibleContext.ACCESSIBLE_STATE_PROPERTY,
                    null, AccessibleState.ENABLED);
    }The main difference appears to be with the KeyboardFocusManager. So instead of using a toolbar, I changed it to a JPanel (so the buttons are focusable). I then notice the same lag when I try to tab between the two buttons. So the problem is with the focus manager, not the setEnabled() method.

SRM event handler creation

Hi experts,
we are trying to configure a questionnaire on the SRM.
We would like to know if it is possible to put control on fields (example: field has to be numeric and of 5 digits. If the vendor writes only 4 digit the quastionnaire should not be sent). Is it possible to create a control by using event handler? How and where do I have to write the function?
Thanks in advance,
Regards,
Riccardo

Hi Chandra,
when I have to deal with dependent values I normally do the following:
Raise a Server Side Event in GET_P method as you did
In the GET_V method I build up the value help and store it in a global variable on the context node. In the GET_V you have got access to the current entity with collection_wrapper->get_current() --> meaning you can always have the correct value of all the fields and read dependent on them.
In the implementation class create an event handler that clears the global variable for the dependent value help whenever a new value is selected in the leading field.
I suppose you have got a similar setup.
One possibility to circumvent your problem is to skip the step with the global variable. Just shoot the server side event. This leads to a server roundtrip and the valuehelp for the dependent field is calculated again, based on the updated value of the leading field.
However, this method is not very good for performance! Thus I would normally keep away from it.
Concerning your problem with the wizard. It is correct that you have to have the view created with the wizard to be able to use it later on. On copied views the wizard does some redefinitions of common methods and it does complain if they are not exactly as it expects them.
For event handlers I believe this should only be the DO_HANDLE_EVENT in the parent class of your IMPL. Meaning if you inherit from a SAP view inheritance is as follows: SAP class --> SAP class _IMPL --> Your class --> Your class _IMPL
The DO_HANDLE_EVENT would have to be in the Your class.
An easy way would be recreating the view using the wizard (be sure to restart the component workbench after this).
Another is create the event handler manually. Copy an existing EH_ONXXX method, and add a CASE statement into the DO_HANDLE_EVENT that calls this copied method.
cheers Carsten

Project Server Event Handler Installer

Hi!
I created my first Event Handler to the Project Server and my question is how can I create installer to this solution?
I'm looking for the best way to install solution to other farm, but I'm new in Project Server.
Please help!
Thanks,
Mykie

Hi Mykie,
To deploy a Server Side Event Handler, you have to do 2 things:
Install the Assembly in the Global Assembly Cache (GAC)
Link your assembly to the Event in Project Server
For the first operation, I would recommand to create a SharePoint WSP solution. It's the simplest way to deploy assemblys in a farm. Another possibility is to use GACUTIL to register the assembly, but it's not always possible in a production environment.
For the second operation, you have to associate your assembly to the Server Side Event:
(detailed procedure here:
http://technet.microsoft.com/en-us/library/gg982976(v=office.15).aspx )
On the SharePoint Central Admin / Application Management / Manage Service Application / PWA / Manage / Operational Policies/ Server Settings/ Server Side Event Handler
Select the correct Event Handler
Copy and paste the assembly info: fully qualified name, order...
After that, the Handler is operationnal.
Hope it helps,
Sylvain

About CL_GUI_ALV_GRID's event-handling & PAI/PBO

Hi, all,
I met a problem when using CL_GUI_ALV_GRID's event-handling.
I created a simple event-handling-class with an event-handling-method for DOUBLE-CLICK event of CL_GUI_ALV_GRID. And the event-handling-method, only makes some changes to the contents of itab to be shown in ALV_GRID.
The problem is: In my idea, after event-dispatch and event-handling in PAI, subsequent PBO will be called. Since SET_TABLE_FOR_FIRST_DISPLAY is called in PBO, I would saw the changed itab shown. BUT, I saw the contents of the itab remaining unchanged.
* PAI module, DISPATCH the event
CASE OK_CODE.
    WHEN OTHERS.
      CALL METHOD cl_gui_cfw=>dispatch.
ENDCASE.
I debugged, and found that, after event-handling-method, PBO module doesn't execute.
That's my wondering, after the preceding PAI, shouldn't the subsequent PBO appear? OR is event-handling different from other user actions?
Many thanks.

Event handler Creation in CRM Webclient UI

Hi,
In CRM Webclient UI, we are using service application.
We have enhanced some fileds through eewb.
Few of them are dependent dropdowns. on change of one dropdown other dropdown values needs to be loaded.
To load the values dynamically, In the get_P_XYZ method of the field XYZ , i have raised an event DDLB_ONSELECT.
I am new to bsp applications. I want to generate event handler for this. I tried to create the event handler using the wizard. But i am getting the error - View not copied with wizard; processing not possible.
Please guide me how to create an event handler for the corresponding event or solve the error.
-Chandra Sekhar.

Hi Chandra,
when I have to deal with dependent values I normally do the following:
Raise a Server Side Event in GET_P method as you did
In the GET_V method I build up the value help and store it in a global variable on the context node. In the GET_V you have got access to the current entity with collection_wrapper->get_current() --> meaning you can always have the correct value of all the fields and read dependent on them.
In the implementation class create an event handler that clears the global variable for the dependent value help whenever a new value is selected in the leading field.
I suppose you have got a similar setup.
One possibility to circumvent your problem is to skip the step with the global variable. Just shoot the server side event. This leads to a server roundtrip and the valuehelp for the dependent field is calculated again, based on the updated value of the leading field.
However, this method is not very good for performance! Thus I would normally keep away from it.
Concerning your problem with the wizard. It is correct that you have to have the view created with the wizard to be able to use it later on. On copied views the wizard does some redefinitions of common methods and it does complain if they are not exactly as it expects them.
For event handlers I believe this should only be the DO_HANDLE_EVENT in the parent class of your IMPL. Meaning if you inherit from a SAP view inheritance is as follows: SAP class --> SAP class _IMPL --> Your class --> Your class _IMPL
The DO_HANDLE_EVENT would have to be in the Your class.
An easy way would be recreating the view using the wizard (be sure to restart the component workbench after this).
Another is create the event handler manually. Copy an existing EH_ONXXX method, and add a CASE statement into the DO_HANDLE_EVENT that calls this copied method.
cheers Carsten

How can I execute an external program from within a button's event handler?

I am using Tomcat ApacheTomcat 6.0.16 with Netbeans 6.1 (with the latest JDK/J2EE)
I need to execute external programs from an event handler for a button on a JSF page (the program is compiled, and extremely fast compared both to plain java and especially stored procedures written in SQL).
I tried what I'd do in a standalone program (as shown in the appended code), but it didn't work. Instead I received text saying the program couldn't be found. This error message comes even if I try the Windows command "dir". I thought with 'dir' I'd at least get the contents of the current working directory. :-(
I can probably get by with cgi on Apache's httpd server (or, I understand tomcat supports cgi, but I have yet to get that to work either), but whatever I do I need to be able to do it from within the button's event handler. And if I resort to cgi, I must be able to maintain session jumping from one server to the other and back.
So, then, how can I do this?
Thanks
Ted
NB: The programs that I need to run do NOT take input from the user. Rather, my code in the web application processes user selections from selection controls, and a couple field controls, sanitizes the inoputs and places clean, safe data in a MySQL database, and then the external program I need to run gets safe data from the database, does some heavy duty number crunching, and puts the output data into the database. They are well insulated from mischeif.
NB: In the following array_function_test.pl was placed in the same folder as the web application's jsp pages, (and I'd tried WEB-INF - with the same result), and I DID see the file in the application's war file.
        try {
            java.lang.ProcessBuilder pn = new java.lang.ProcessBuilder("array_function_test.pl");
            //pn.directory(new java.io.File("K:\\work"));
            java.lang.Process pr = pn.start();
            java.io.BufferedInputStream bis = (java.io.BufferedInputStream)pr.getInputStream();
            String tmp = new String("");
            byte b[] = new byte[1000];
            int i = 0;
            while (i != -1) {
                bis.read(b);
                tmp += new String(b);
            getSelectionsDisplayTextArea().setText(getSelectionsDisplayTextArea().getText() + "\n\n" + tmp);
        } catch (java.io.IOException ex) {
            getSelectionsDisplayTextArea().setText(getSelectionsDisplayTextArea().getText() + "\n\n" + ex.getMessage());
        }

Hi Fonsi!
One way to execute an external program is to use the System Exec.vi. You find it in the functions pallet under Communication.

Copying text to the clipboard in AVDocDidOpen event handler causes Acrobat 9 to crash

I'm trying to copy the filename of a document to the clipboard in a plugin with my AVDocDidOpen event handler. It works for the first file opened; however when a second file is opened, Acrobat crashes. The description in the application event log is: "Faulting application acrobat.exe, version 9.1.0.163, faulting module gdi32.dll, version 5.1.2600.5698, fault address 0x000074cc."
I've confirmed that the specific WIN32 function that causes this to happen is SetClipboardData(CF_TEXT, hText); When that line is commented out and remaining code is left unchanged, Adobe doesn't crash.
Is there an SDK function that I should be using instead of WIN32's SetClipboardData()? Alternately, are there other SDK functions that I need to call be before or after I call SetClipboardData()
Bill Erickson

Leonard,
I tried it with both "DURING, HANDLER, END_HANDLER" and "try catch," as shown below. However, it doesn't crash in the event handler; it crashes later, so the HANDLER/catch block is never hit.
The string that's passed to SetClipboardData() is good, because I'm able to paste it into the filename text box of the print dialog when I try to create the "connector line" PDF. I also got rid of all the string manipulation and tried to pass a zero-length string to the clipboard but it still crashes.
Here's the code:
ACCB1 void ACCB2 CFkDisposition::myAVDocDidOpenCallback(AVDoc doc, Int32 error, void *clientData)
    PDDoc pdDoc = AVDocGetPDDoc(doc);
    char* pURL = ASFileGetURL(PDDocGetFile(annotDataRec->thePDDoc));
    if (pURL)    {
        if (strstr(pURL, "file://") && strstr(pURL, "Reviewed.pdf")) {
            // Opened from file system so copy filename to clipboard for connector line report
            char myURL[1000];
            strcpy(myURL, pURL);
            ASfree(pURL);    // Do this before we allocate a Windows handle just in case Windows messes with this pointer
            pURL = NULL;
            HGLOBAL hText = GlobalAlloc(GMEM_MOVEABLE, 1000);
            if (hText)    {
                try
                    // Skip path info and go right to filename
                    char *pText = (char *)GlobalLock(hText);
                    char *pWork = strrchr(myURL,'/');
                    if (pWork)    {
                        strcpy(pText, pWork+1);
                    } else {
                        strcpy(pText, myURL);
                    char *pEnd = pText + strlen(pText);    // Get null terminator address
                    // Replace "%20" in filename with " "
                    pWork = strstr(pText, "%20");
                    while (pWork)    {
                        *pWork = ' ';
                        memmove(pWork+1, pWork+3, (pEnd - (pWork+2)));
                        pWork = strstr(pText, "%20");
                    // Append a new file extension
                    pWork = strstr(pText, ".pdf");
                    *pWork = 0;    // truncate the string before ".pdf"
                    strcat(pWork,".Connectors.pdf");
                    GlobalUnlock(hText);     // Must do this BEFORE SetClipboardData()
                    // Write it to the clipboard
                    OpenClipboard(NULL);
                    EmptyClipboard();
                    SetClipboardData(CF_TEXT, hText);     // Here's the culprit
                    CloseClipboard();
                    GlobalFree(hText);
                } catch (char * str) {
                    AVAlertNote(str);
        if (pURL)
            ASfree(pURL);
