KeyboardEvent Enter Key

On stage i have a button, TextInput and a TextArea component. I want the user to add some content in the TextInput field and when Enter is clicked on the Keyboard the content will be transferred and displayed in the TextArea. How do i do this? I know the keyCode == Keyboard.ENTER is to recognize when enter is pressed but to do this is more complicated.
Thank You

Assign a listener for a KeyboardEvent and if the event indicates the Enter key was used, write the text to the textarea.
stage.addEventListener(KeyboardEvent.KEY_UP, writeText);
function writeText(event:KeyboardEvent):void {
if(event.keyCode == Keyboard.ENTER){
// write the text to the textarea

Fastest way to create a KeyboardEvent.ENTER submit function.

Hello, a submit button is on the stage next to a text input field. It must be possible to use both mouse and the enter key to press the button.
What's the fastest and easiest way to add an eventListener to the ENTER key, on the button?

So it would have to be something like this? But now the MouseEvent won't work? Do I really have to create a duplicate of the function for both to work? Seems like a hassle..
submitBtn.addEventListener(MouseEvent.CLICK,handler);
stage.addEventListener(KeyboardEvent.KEY_DOWN,handler);
function handler(Event){
if(event.charCode == 13)

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?

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.

Enable enter key

How to enable enter key in adobe flex builder 2

An easy way to enable the enter key for all buttons (when
they have the focus)
is to
- on each button add a click event handler that does what
the button needs to do
- Just add a keyDown Handler to the component that contains
the buttons
- In the key down handler check for the enter key, and if the
target is a button.
If so then dispatch a button click event.
In the code below if the user tabs to a button and presses
enter
the button will be clicked.
See below
private function handleKeyDown(event:KeyboardEvent):void
var char:uint = event.keyCode;
var enterChar:uint = 13;
var tabChar:uint = 9;
var pgUp:uint = 33;
var pgDown:uint = 34;
if(char == enterChar)
if(event.target is Button)
var bt:Button = event.target as Button;
if(bt.enabled == false || bt.visible == false)
return;
var c:MouseEvent = new MouseEvent(MouseEvent.CLICK,true);
bt.dispatchEvent(c);
return;

How to activate a button with Enter key?

Hi
I was certain that in AC3 this is done by default, when the button is in focus and the ENTER key is press, it dispatches a Click event.. but it doesn´t work, am I missing something?? Thanks for your help.
myButon.addEventListener("click", funClick);
function funClick(evtObj:Event):void {
trace("yes");

if you have btnNum buttons with names btn1, btn2,... and they each have a listener function f1(), f2(), ... you can use the following to code for them all and the enter key:
var btnNum:uint=2;
for(var i:uint=1;i<=btnNum;i++){
    this["btn"+i].addEventListener("click", this["f"+i]);
    this["btn"+i].addEventListener(MouseEvent.MOUSE_OVER,overF);
    this["btn"+i].addEventListener(MouseEvent.MOUSE_OUT,outF);
stage.addEventListener(KeyboardEvent.KEY_DOWN,f);
function overF(e:MouseEvent){
    stage.focus = InteractiveObject(e.currentTarget);
function outF(e:MouseEvent){
    stage.focus = null;
function f(evtObj:KeyboardEvent):void {
    if(KeyboardEvent(evtObj).keyCode==13 && stage.focus != null){
        stage.focus.dispatchEvent(new Event("click"));
// define your f1(), f2() etc functions

Get Buttons to respond to ENTER key

What's the best way to get a button to respond to the ENTER
key (when the given button has focus)?
As of now I'm checking the ID of object that has focus (in
the main application), and it seems to work fine, as below:
private function goKey(event:KeyboardEvent):void {
. if (event.keyCode == Keyboard.ENTER) {
. . var iF:Object = getFocus();
. . if (iF.id == "myButton") {
. . . // execute code here
... but I'm wondering if there's a more elegant way to do it,
which will open up my understanding of Flex.
thanks.

There are probably lots of ways to handle this. I typically
add my keydown
handler on the container that holds the buttons
then in the event handler look at the event.target. It its a
button then
dispatch a mouse click event. Then the click event handler
for the button
will be called as if the user clicked it with a mouse.
just do this:
private function handleKeyDown(event:KeyboardEvent):void
var char:uint = event.keyCode;
var enterChar:uint = 13;
var tabChar:uint = 9;
var pgUp:uint = 33;
var pgDown:uint = 34;
if(char == enterChar)
if(event.target is Button)
var bt:Button = event.target as Button;
if(bt.enabled == false)
return;
var c:MouseEvent = new MouseEvent(MouseEvent.CLICK,true);
bt.dispatchEvent(c);
return;
}

How to refresh changed data in a plannable template with the Enter Key

Hi,
The situation I face is as follows.
Integrated Planning is being implemented as a tool for budgeting. The user changes a value in a plannable cell on the portal and wishes to see the new updated data by pressing ENTER. Currently we have provided a REFRESH button so that the user gets the desired result.
Is it possible to see the updated value by pressing ' ENTER' and if so , whats the way around to do it.
thanks in advance.
Jaya

Hey guys,
I'm interested too in this solution. In BPS there is an additional function described in the HowTo Paper HowTo run planning functions on save and other events
Now I'm looking for this possibility in IP as well in excel-based IP and web-based IP. For example a copy function should be executed automatically when pushing the enter key.
Thanks a lot!

Table Control[Accept Input Only] - "ENTER" Key

Hi Folks,
I'm reviving this unanswered thread in relation to table control: when the user press enter, all the values entered disappear.
[url]Re: Table control (Enter key)[url]
I have a table control that accepts "ONLY" input, meaning to say, there will be no pre-loading of data in the PBO, so it will loop through the table control itself instead of looping from an internal table.
Issue: Whenever I press "ENTER" in any column/row of my table control, ALL the values I entered disappear.
PBO:
PROCESS BEFORE OUTPUT.
MODULE CLEAR_OKCODE.
MODULE LOAD_TABLECTRL.
LOOP WITH CONTROL TC_DATA.
    MODULE READ_DATA.
ENDLOOP.
module READ_DATA output.
READ TABLE T_DATA INTO WA_DATA INDEX TC_DATA-current_line.
data : line_count type i.
"to increase the number of lines in table control dynamically
describe TABLE t_data lines line_count.
TC_DATA-lines = line_count + 10.
endmodule.
PAI:
PROCESS AFTER INPUT.
LOOP WITH CONTROL TC_DATA.
    MODULE MODIFY_DATA.
ENDLOOP.
module MODIFY_DATA input.
WHEN 'CREATE'.
"subroutines are here, etc.
WHEN 'DELETE'.
WHEN 'BACK'.
LEAVE TO SCREEN 0.
endmodule.
In my ABAP Debug, the value of SY-UCOMM is BLANK whenever I press Enter.
Thanks.

Hi
Your code seems to be rght only the MODIFY statament is useless:
module READ_DATA output.
READ TABLE T_ID_CHECK INTO WA_ID_CHECK INDEX TC_ID-current_line.
IF SY-SUBRC EQ 0.
    ZQID_CHECK-WERKS = WA_ID_CHECK-WERKS.
    ZQID_CHECK-MATNR = WA_ID_CHECK-MATNR.
    ZQID_CHECK-LICHA = WA_ID_CHECK-LICHA.
    ZQID_CHECK-LIFNR = WA_ID_CHECK-LIFNR.
ELSE.
    CLEAR ZQID_CHECK.
ENDIF.
endmodule.
Now before LOOP of PBO try to set the lines of table control to be display, I've created this report on my system and it works fine:
.CONTROLS T_CTRL TYPE TABLEVIEW USING SCREEN 100.
DATA: BEGIN OF ITAB OCCURS 0,
          WERKS LIKE MARC-WERKS,

    ITAB-WERKS = '5010'.
    ITAB-MATNR = '1234567890'.
    ITAB-LIFNR = '0000000001'.
    APPEND ITAB.
ENDDO.
CALL SCREEN 100.

Buttons and enter key problem

hello,
there are a few projects of enterprise quality which I am developing in java swing. I found out through research that many or rather most people involved with java believe that swing is ready for enterprise class robust desktop applications.
so I as the team leador am starting my new projects in java swing.
I personally find that the amount of java libraries present provide a rich set of functionality and it gives big mussle power to the developers.
I am only concerned about one problem which many of you might have solved.
I find that I have to hit the space bar instead of enter key to fire an action. in languages like vb I can press enter key to fire the click events. specially in menu items I certainly don't expect my clients to press the spacebar. besides there are many people who are so used to the keyboard and enter key in particular that it will be hard or rather next to impossible to change their habbits.
how can I make the menu items work with the enter key. I mean do I need to create the code for keypress events every time I also create an action performed method? or is there a way where I can do it without extra coding.
it is just that I don't want to right extra code for enter key along with click events.
one more important note.
I am a blind person and I use the access bridge technology of java.
so when I am involved in coding, I use the same.
so may be my problem isn't a problem in the first place.
kindly provide me some help
thanks
Krishnakant.

The enter-key works on menu-items in all my applications. It did so since I started with java few years ago.
Maybe some other problem (OS-specific) ?

Enter Key is not being accepted properly in the Applet

We have developed a Telnet application which is in form of an Applet. We are facing some problems with respect to that.
We are using Java 1.2.
When login sessions are launched, the login prompt is displayed.
After we enter the user id and press the "Enter" Key, the UI remains at the "user id" prompt and is not accepting the "Enter" Key.
As a result, we are not getting the password prompt and hence NE UI is not deing displayed.
This was verified with logs and found that the "Enter" key was interpreted as "char 7" instead of Ascii char 10(Enter Key).
This problem was observed in both IE and Netscape.
But this same code works fine when it is run as a Java application. Also the same applet works fine when viewed from the Applet Viewer.
Iam of the view that the issue may be due to the restrictions imposed by the browsers on the Java Applet.
Please give me suggestions to circumvent this problem ,if u have faced the same.
Thanks in advance,
Darshan

The reason why ENTER doesn't work is because it's reserved for the default button. The SPACEBAR does what you want.

LM13: Verification field not cleared after [Enter] key

Hi Experts,
I'm facing the issue as stated in the OSS note 916654 - LM13: Verification field not cleared after [Enter] key. My current system is ECC, that is why the OSS is already applied to the ECC version. But the problem is, i still faced the problem stated in the OSS.
Symptom
In customizing:
- You have defined [ENTER] in destination screen 302 to SAVE items.
- You want to verify the destination bin information.
You use 'Confirm Transfer Order Clustered' RF transaction LM13.
You scan several SUs and press enter.
You press [F4-Next pushbutton] to confirm the associated TO(s).
In the destination screen 302, you scan the verification value for the first item and press [ENTER] key.
==> The item is confirmed correctly but when the system proposes the next item, the verification value of the first item is displayed.
Anyone know how to fix this issue? Pls help.
thanks

Action for ENTER KEY is not working in alv grid output (Classical)

Hi Experts,
I have searched SDN around 8 hours and could not get any help on my below issue.
I am developing ALV report using function module (Classical ALV). ALV output has 4 input enable fields, if user enters data in any of those fields and clicks on enter button from key pad..the remaining fields needs to be filled automatically.
I am facing the issue with enter key, even if i press enter key in the output there is no action and hence no user command triggered. May be i am using wrong funcion code in wrong way.
Could any one tell me what function code can we assign for ENTER action in PF-STATUS?

Submitting a form with enter key causing strange problems

I am having a very strange problem with a webapp I am currently developing. I am using JSF 1.2 along with Facelets and RichFaces. I have coded a workflow/wizard 4-step process, and on some pages I have 4 submit buttons that all call different actions on the page. The users thought it would be useful to have the enter key submit the form, so I followed some online resources to trap a keypress using javascript, looking for the enter keycode and calling document.getElementById("elementName").click(). This works fine most of the time. Sometimes, though, it seems as if an entire new session is being created, and odd behavior starts happening. For example, my page will only include 2 of the 4 facelets on the screen -or- I will get NullPointerExceptions for objects that I know have been created in the session bean I am currently using -or- I will get a duplicate form Id after trying to re-submit the page. Could the javascript click simulation not be submitting all of the form elements or is the enter key also acting like its default action (the form submission) in addition to the "click"? I'm really at my wit's end here (plus it's nearly 3 AM, that never helps things). All of the buttons being clicked are standard h:commandButtons. There is some setTimeout logic included to disable the buttons on the page to prevent double clicks (I cannot disable them onsubmit because disabled buttons don't pass the right values, perhaps that's causing it, but if so, clicking the buttons with the mouse would cause that issue too, right?)
I am not posting the code (yet), but if anyone wants to take a look see and see if I am doing something really abhorrently wrong, I'm more than willing to, I'm just curious if anyone has had problems regarding javascript submission of forms via the click() method. Clicking the button does not exhibit this type of behavior. Just as a side note: I am doing different things with the enter key depending if a modal window is open (the enter key closes the modal if it's up, and if not, it submits the form via a button click).
Any help is much appreciated, if anyone has any inkling about where I should start looking for answers it would be really helpful.
Thank you.

You need to suppress the event handling after programmatically clicking the button.

Since upgrading to Firefox 10.0.2 my AVG extension has had to be disabled, as after typing in any web address in the address bar, the enter key had no effect and I could not go to the site without pressing the Reload arrow on right.

I have recently upgraded Firefox to the latest version 10.0.2. After that I could not enter any website address and press the enter key and get to the website, nor could I select a website from the dropdown list of previously visited websites. The only way I could get there was by pressing the arrow on the right side of the address box (Reload current page). Once I disabled the AVG extension, everything worked normally. As soon as I enabled the AVG extension, it stopped working again.

Follow these steps for the controls to work:
# Start > Programs > Mozilla Firefox > Mozilla Firefox
# Find the “Tools” menu at the top of the browser window and select “Add-ons”.
# Click on the “Extensions” icon to make sure you’re in the correct option menu.
# Locate “AVG Safe Search” and click on the containing line to highlight and select the add-on.
# Click the “Disable” button and close the Add-ons window.
# Close down any Firefox windows you may have open.
# That’s It – You’re Done!
