Disable datagrid keyboard events

Is it possible to disable keyboard events or prevent the datagrid from switching selected rows? In my app, I allow the user to select a datagrid row, but when they do I make a request to get data. While I am waiting for the data to return I want to prevent the user from using the keyboard arrow keys to select another row.
I have tried setting selectable to false and setting focusEnabled to false, but neither one works. Anyone know of another alternative?
TIA

Block the keyDown event or override moveSelectionVertically

In Flashplayer, I can crossover mouse and keyboard events. In IrfanView I cannot. Can this be fixed?

My client uses IrfanView to play SWF files. Unfortunately, he does not use Flashplayer. In Flashplayer, I can crossover mouse and keyboard events with no problem. In IrfanView, the second I click a button, the keyboard events are disabled. Is there a fix?

Hi Ned. I may have posted this issue a bit early, but this problem is also happening in Flashplayer 10. It's not exclusive to IrfanView.
Here is something that I encountered during my testing, when I jump to scene 6 using the menu button, I have a play button to jump from one frame to the next frame that stops -- the keyboard events start working. But if all I am doing is jumping scene to scene with the mouse button, the keyboard events are disabled.
I feel as if the keyboard events only work if I am playing frames in the scene. And if all I am doing is jumping scene to scene using the buttons, the keys will disable.
I set up the mouse buttons inside a movieclip that all the scenes share. The mouse actionscript is in the movieclip. On the main timeline of each scene is an actionscript for the keyboard events, even though I had to change each function name.
I feel the actionscript is setup pretty simple. I just wish clicking the buttons would not disable the keyboard events. This may sound redundant, but the keyboard events do the same thing if you use the mouse buttons. It's just preference for the client even though he will need to understand that using the mouse buttons override the keyboard events. He doesn't really lose functionality.
Keyboard actionscripting below:
import flash.events.KeyboardEvent;
stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyEvent);
function onKeyEvent(e:KeyboardEvent):void {
var character:String=String.fromCharCode(e.charCode);
if (e.keyCode==72) {
gotoAndStop(1,"master");
if (e.charCode==49) {
gotoAndPlay(1,"Distributor");
if (e.charCode==50) {
gotoAndPlay(1,"Mirka");
if (e.charCode==51) {
gotoAndPlay(1,"Farm");
if (e.charCode==52) {
gotoAndPlay(1,"Check2");
if (e.charCode==53) {
gotoAndPlay(1,"Check3");
if (e.charCode==54) {
gotoAndPlay(1,"Scene2");
if (e.charCode==55) {
gotoAndPlay(1,"Scene1");

Disablying keyboard events in a JFrame.

Hello,
How is it possible to disable keyboard events for a specific JFrame and then (after a while) enable events again ?
thank you,
Rami

Look at this program, events are send but you can't see the data in the fields.
import java.awt.*;
import java.awt.event.*;
public class Nok extends Frame
public Nok()
     super();
     setBounds(6,6,400,300);
     addWindowListener(new WindowAdapter()
    {     public void windowClosing(WindowEvent ev)
               dispose();
               System.exit(0);
     setLayout(new GridLayout(4,0));
     add(new TextField("this is a text field"));
     add(new TextArea("this is a text area"));
     add(new Button("this is a button"));
     setVisible(true);

               ((KeyEvent)e).consume();
     }   ,AWTEvent.KEY_EVENT_MASK);

Disable a keyboard key control in listview

how to disable a keyboard key control in listview ?
example
page down
Thank's

Register an event filter and consume the event before it gets processed by the list view. Specifically for page down it can look like this:
listView.addEventFilter(KeyEvent.ANY, new EventHandler<KeyEvent>() {
 @Override public void handle(KeyEvent event) {
 if (event.getCode() == KeyCode.PAGE_DOWN) {
 event.consume();

Keyboard events going to InDesign and not on textbox

Hi,
I have ported a project from InDesign CS2 to InDesgn CS3 on Mac. I have dialogs in rsrc file (not converted to nib file) which I am also using on XCode.
Now the problem which I am facing is that when typing in a textbox then keyboard events are going to InDesign and only those events which are not handled by InDesign is received by my textbox.
Has anyone experienced the same problem before?
Any help will be appreciated.
Regards,
Rahul Rastogi

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). 
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]] 
 
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. 
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions. 
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

How do you disable all-day event notifications?

I've already read the various threads about the issues with all-day events disappearing from the Today view and only appearing in the Notifications. However, I am having an issue when trying to disable all-day event notifications. I currently use my all day events from my work calendar (Lotus Notes 8.5) that is synched to my phone. I have disabled the "Notify Me" option within Lotus Notes and changed the default all day event notification on my phone to "None". The problem is that this has not disabled any all day event notification and I still get notified every night at midnight for the event. This didn't happen on iOS 6 or any of the iOS 7 beta versions. Is this something that can be fixed? Thanks!

the Automation quick access should be off by default. I don't think this is what will do it for you, but here is a description of it, Page 320 of the manual
Automation Quick Access
This feature makes Track Automation extremely fast and simple if you only have one hardware MIDI controller available (one fader on your MIDI keyboard, or maybe just the Modulation wheel). You can use this single hardware controller to access (and automate) the currently visible Automation parameter of the selected Track in the Arrange window.
since it is midi messages that you do not want to send from your controller, I think you need to go to song settings an filter out incomming midi messages. File>song settings>midi>imput filter
but really any messages being sent should only effect the channel you are playing. I am assuming you are playing one of logics instruments for live performance.

Mouse & Keyboard events

Hi all,
I�m creating an applet and this applet needs to use both keyboard and mouse events�. My problem is that when I try to enable mouse events, such as mouse click, using either this.enableEvents(AWTEvent.MOUSE_EVENT_MASK) in init() method, or using mouse listener:
public class ThreeDSimApplet extends Applet implements Runnable, MouseListener
and defining the required methods:
public void mouseClicked(MouseEvent event) {
if (event.getButton()==MouseEvent.BUTTON1) {
mouseX=event.getX();
mouseY=event.getY();
System.out.println(mouseX+" ," + mouseY);
public void mousePressed(MouseEvent event) {
public void mouseReleased(MouseEvent event) {
public void mouseEntered(MouseEvent event) {
public void mouseExited(MouseEvent event) {
the keyboard events become disabled and my keyboard doesn�t works anymore�. Exist a way to use both events in my applet?
Bye and thanks

Hi
This doesn't answer your question exactly, but I suggest implementing
a MouseAdapter instead of a MouseListener.
That way you won't have to implement all the unused methods
(eg mouseEntered, mouseExited etc.); just the one(s) you need
See http://java.sun.com/docs/books/tutorial/uiswing/events/generalrules.html#eventAdapters
Good luck for getting an answer to you question!

Flex 4 does not dispatch keyboard events for ENTER key.

Hello everyone. I think I have a strange problem with Flex 4 Beta (4.0.0.8909). My application has had event listener for keyUp event for a month now and suddenly (two days ago) I've noticed that keyUp event is not dispatched for ENTER (ALT also) key. Anyone know why? By the way, I've tried this with keyDown event, also 4.0.0.8847 version of SDK - still the same: no keyboard events for ENTER (and ALT) key.
Here is the sample application that has got this issue:
<s:Application
 xmlns:fx="http://ns.adobe.com/mxml/2009"
 xmlns:s="library://ns.adobe.com/flex/spark"
 xmlns:mx="library://ns.adobe.com/flex/halo"
 minWidth="640" minHeight="480"
 keyUp="application1_keyUpHandler (event)">
 <fx:Script>
 <![CDATA[
 import mx.controls.Alert;
 protected function application1_keyUpHandler (event: KeyboardEvent):void
 Alert.show ("Key up: " + event.keyCode);
 ]]>
 </fx:Script>
 <s:layout>
 <s:BasicLayout/>
 </s:layout>
 <s:TextArea verticalCenter="0" horizontalCenter="0" width="200"/>
</s:Application>
If you run this application and try typing anything in a TextArea you will get alerts with key codes. However, if you press ENTER (or ALT), you will get no alert.
I'm pretty sure the code above is right so that means there is a bug in latest nightly builds of SDK (i would swhitch to an older build if i knew which one does not have this bug).
Any ideas?

Flex harUI wrote:
That's true, but in this case, I think the text editing code is eating ENTER key in order to prevent parents from seeing it and acting on it (like a submit button). We'll see if we can find a way around that.
You can get the ENTER key now by listening in capture phase.

The enter key isn't being disposed of by textedit, the attached example code works without error if you a- remove the alert box and b-set the focus to your text area on initialisation. I agree that pressing the enter key then calling a dialog box will result in the enter key being "gobbled up" as the enter key is overridden by the dialog box code.
I think the first suggestion should be to anyone don't use dialogboxes for testing code. If for some reason debugging isn't desirable instead of a trace statement a simple label can be used as a 'fake' trace.

Message was edited by: David_F57: I worded this wrong, imho there is no need for a work around, the textarea component works as it should. When intercepting 'system' keycodes there is a need to consider the effect of the intercept and code appropriately to that end.

Keyboard Event Listener doesn't work in Browser

Is there a reason why a keyboard event listener would not work if the flash is embedded in an HTML? The rest of my game is running fine in the background, but I can't launch the movieClip "nextCar." My code is below, if that makes any difference...
function goNow (event:KeyboardEvent): void {
    thisOtherKey = event.keyCode;
    if (thisOtherKey == 32) {
        nextCar.gotoAndPlay(2);
        parkingQue.play();
        tries++;
stage.addEventListener(KeyboardEvent.KEY_DOWN, goNow);

This may be a silly question, but have you tryed clicking on your swf after it opens up in the browser, and then trying the keyboard controls?
I don't know of any issues that cause event listeners to workwhen debugging, but not in a browser. So, I'm thinking maybe your just not focused on the swf.

Can we catch keyboard event triggered by an inputfiled?

Hi all,
I have a question here:
When we are doing the web dynpro abap development, if I want to catch the keyboard triggered by an
input help and handle it, how can I achieve this?
e.g. I have an inputfield on the UI, if user click "F10" on the keyboard, can I catch this kind of event?
Thanks and Regards,
Aaron

Hi Thomas,
Yes, I'm trying to acomplish an input help for an inputfield.But, the free programmed value or OVS or dictionary search help can fullfill my needs.Here is the situation:
I have a inputfield on the UI, and next to that , I have another textview, which should be changed according inputfield. e.g. the inputfield is a user name, and next to that , is the user id. but we only want the input help for user name. so when user select one row iof the search result table, I want that two fields both filled.
1. the OVS can't meet my need because I can't change the layout of the search result table, I need a table with a tree in it.
2. free programmed value help can only send back the value of the inputfield. although maybe I can get the user_id's context attribute name and by hardcoding and send back also the user id. but I don't like hardcoding.
So, I'm wondering whether I could catch the keyboard event. and handle the F4 help all by myself.
Do you have some suggestion on this?
Thanks and Regards,
Aaron

Getting keyboard events on ALV grid

Hi,
I have an ALV Grid where it is possible to edit data. If user selects a row and presses delete/cut button with mouse event is triggered and I can access those events in code. Although if user selects a row and presses "Del" or "Ctrl + X" then I can't access those events in code. Is there a way to access keyboard events inside my code?

Have a look at BCALV_GRID_EDIT -> if you select the first checkbox (p_cell = Update on cell change) then you will find that "data_changed" event can catch the line deletion via the keystrokes described.. in the event in this program, you could get the rows deleted from "rr_data_changed->mt_deleted_rows".
if p_cell = 'X'.
call method grid1->register_edit_event
exporting
i_event_id = cl_gui_alv_grid=>mc_evt_modified.
else.

[solved] send keyboard event / key to specific background window?

Hi!
So... is this possible / how? I'd like to send keyboard events to a window in the background - maybe even in regular intervals. While I'm dong something else, in another window (or nothing).
Thx!

Actually I'm thinking, maybe there is a totally another (better?) way to do what you want. I usually find that automatizing tasks in linux differs very much from the windows experinece, most of the times scripting is the most powerful and easy way of doing things. So if you describe to us what you want to accomplish, maybe some experienced linux gurus would give you some advices that sets you off course from sending keys and mouse events. I used to do that in windows with autohotkey, but now in linux there was no need for that so far ever, except for using system wide abbreviations with autokey.

Disable Sharepoint 2010 Event Handler

I have two different event handler solutions in a list. One event handler runs on multiple lists if an Item is being Updated. Lets call that event handler (A). I have another event handler that runs on only one list. Lets call that event handler (B). Both
the event handlers (A) and (B) runs on the list that I am talking about. When an item is being updated, I have some scenarios when I want to disable event handler (B) but not (A). Event Handler (A) should run as usual. How do I disable just one event Handler?
I am using the code below to disable and enable the event handlers. This is disabling both the event handlers.
EventFiring eventFiring = new EventFiring();
eventFiring.DisableHandleEventFiring();
....some code
eventFiring.EnableHandleEventFiring();

Hi,
According to your description, you may want to manage the execution of the two Event Receivers for a specific list.
As a common practice, it is not recommended to control an Event Receiver from another Event Receiver, I would suggest you use the Event Receiver (A) only to capture the ItemUpdated event.
Since you might have different logic in the two Event Receivers, a possible workaround I can provide is that you can execute the two different logic accordingly by checking the name of the list which the item event occurs in, usually, an if…else… block would
do the trick.

Handling keyboard events in applets?! Possible?!

Hello,
I wrote a little game that uses keyboard handling events. It is an applet that can also standalone as an application. When i run the program as a standalone application, it handles keyboard inputs fine. ie...i can press the left and right arrow keys and something happens.
But when i run my program as an applet in a web browser, the applet starts up correctly but does not handle any keyboard events. It only handles mouse events. For instance, if i press the up and down arrow keys, the browser window scrolls up and down!!! And the up and down arrow keys have a specific purpose in my applet.
QUESTION: how do i get my applet to accept keyboard inputs such as UP,DOWN, LEFT, RIGHT?

Hmm something went wrong w/ my post so i hope this doesnt show up twice.
Hey thanks a lot for helping me out. The applet/application is large so here is the main() method and the keyboard event handling class code. My question is how come the keyboard events get properly handled when i run it as a standalone application, but keyboard events go to the browser when i run it as an applet? I would post my entire code but it's over 1000 lines and spread out over 8 files. hehehe.
Here is main():
public static void main(String[] args)
      MyProgram applet = new MyProgram();
      applet.isStandalone = true;
      JFrame frame = new JFrame();
      frame.setTitle("Physics: Kinematics");
      frame.getContentPane().add(applet, BorderLayout.CENTER);
      applet.init();                        // initialize the applet inside frame
      applet.addKeyListener(kbHandler);     // kbHandler is a keyboard handling object
      applet.start();
      frame.setSize(APPLETWIDTH,APPLETHEIGHT);
      Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
      frame.setLocation((d.width - frame.getSize().width) / 2, (d.height - frame.getSize().height) / 2);
      frame.setVisible(true);
      // private inner class to terminate the Application when frame closes
      frame.addWindowListener(
        new WindowAdapter()
            public void windowClosing(WindowEvent e)
                System.exit(0);
      frame.show();
   }"kbHandler" is the keyboard event handling object. It gets initialized in the applet.init() method.
kbHandler = new BMkeyboardHandler();And here is the keyboard event handling code:
// ===== keyboard event handler ===========
   private class BMkeyboardHandler implements KeyListener
        public void keyPressed(KeyEvent e)
            pushedKey = e.getKeyCode();
            // General administrative key actions
            if(pushedKey == KE.VK_H)
                actionArea.toggleHelpMenu();
                actionArea.repaint();
            else if(pushedKey == KE.VK_C)
                actionArea.toggleCtrlMenu();
                actionArea.repaint();
     }So there it is. Again, the program handles events fine as a standalone application. But running it as an applet in a browser (and even the appletviewer) doesnt let me handle keystrokes.
