Capturing Enter key event from text box

In my application, there are a number of text boxes. I want to create a feature where an enter key even is seen and specific function executed depending on which text box was in focus when the enter key was pressed. Currently I am able to capture an enter key event on the whole page. How do I do that specifically for a text box?
This application is done in HTML, javascript and Adobe AIR.
Thanks

Hi
That's true that Flex4.5 SDK under Flash builder Burito doesn't listen Enter key in Text Area for KeyUp or KeyDown event.
Here I found a work around you can use.
Add an eventlistener to the component in actionscript and set the useCapture=true next to eventlistener function. Now you can listen enter key for KeyUp or KeyDown Event
Hope this helps

Flex4.5 SDK under Flash builder Burito doesnt dispatch Enter key event in Text Area anymore

Flex 4.5 under Flash builder Burito doesnt dispatch 'Enter' key event in Text Area anymore, in prev version 4.1 it was working properly, this stopped working after migration to Burito + Flex SDK 4.5?
What that suppose to be?

Capture 'Enter' key event

Hi,
Is there any way we can capture the event when a user presses the enter key inside a text field?

Hi andrewquay
you can capture the enter key by adding the following code in the textfield's change event.
if(xfa.event.change == "\u000a")
xfa.host.messageBox("enter key is pressed");

Remove the Enter key binding from a JPopupMenu

Hi,
Does anyone know how to remove the Enter key binding from a JPopupMenu?
So when the popupmenu is showing and you type Enter, nothing should happen and the menu should stay where it is.
I have tried:
popup.getActionMap().put("enter", null);
popup.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0), "enter");but the popup always disappears.
Any ideas?
Cheers,
patumaire

First of all, that is not the proper way to "remove" a key binding. Read the Swing tutorial on [How to Use Key Bindings|http://java.sun.com/docs/books/tutorial/uiswing/misc/keybinding.html#howto] for more information.
However, we still have a couple of problems:
a) the input map is dynamically built as the popup menu is displayed
b) the input map is built for the root pane, not the popup menu
The following seems to work:
popup.show(...);
InputMap map = getRootPane().getInputMap(JTable.WHEN_IN_FOCUSED_WINDOW);
map.put(KeyStroke.getKeyStroke("ENTER"), "none");
KeyStroke[] keys = map.allKeys();
for (int i = 0; i < keys.length; i++)
     KeyStroke key = keys;
     Object action = map.get( key );
     System.out.println(key + " : " + action);

KeyListener does not capture Arrow key Events in textField

Love................
I added a key listener to TextField it does not detect
Arrow Keys events in keyTyped, KeyPressed,KeyReleased methods
why?????
I want to shift focus from a textfield to other component
on capturing Arrow key Pressed How

Here is a Java demo where it works since it is not a printable character you must get the keyCode:
http://java.sun.com/docs/books/tutorial/uiswing/events/example-swing/index.html#KeyEventDemo
public class KeyEventDemo ... implements KeyListener ... {
...//where initialization occurs:
     typingArea = new JTextField(20);
     typingArea.addKeyListener(this);
/** Handle the key typed event from the text field. */
public void keyTyped(KeyEvent e) {
     displayInfo(e, "KEY TYPED: ");
/** Handle the key pressed event from the text field. */
public void keyPressed(KeyEvent e) {
     displayInfo(e, "KEY PRESSED: ");
/** Handle the key released event from the text field. */
public void keyReleased(KeyEvent e) {
     displayInfo(e, "KEY RELEASED: ");
protected void displayInfo(KeyEvent e, String s){
     char c = e.getKeyChar();
     int keyCode = e.getKeyCode();
     int modifiers = e.getModifiers();
     tmpString = KeyEvent.getKeyModifiersText(modifiers);
     ...//display information about the KeyEvent...
}

Paste does not work in Safari browser to enter copied content into text box

For example when I go to copy a URL Sosa to paste it into a text box on a local newspaper comment section, it won't paste in. Same goes for any pasting into the text box. I highlight what I want to copy (or cut) and the go to paste it into the text box, and nothing happens. Also there is this problem of the cursor not wanting to go where you direct it with your finger on the touch screen, where you have to get out of the data entry mode altogether then get back in to be able to continue typing to enter text, an d to add to the frustration, the cursor won't go where you want it to, but seems to arbitrarily choose an other place in the middle of the word next to where you want it to! Anyone experience this? I can't believe I'm the only one.

Please don't take offense, you can't believe what some people post and then realize later that they have had a "duh" moment.
I don't know what to suggest other the basic fixes, rebooting (holding the sleep and home buttons down until the Apple logo appears) and see if that helps - maybe clear the cookies and data in Safari even though that should not have any bearing at all on this issue or so I would think.
I can relate to the cursor jumping on the screen issue as I do experience that from time to time. Not quite as bad as you seem to experience it, but it does happen to me as well. I have found that I get the best results using a light touch. And of course I will also enlarge the screen as well if I get too frustrated with the insertion point.
Can we assume that you can copy and paste with the success in email, notes, etc?

Enter Key Event in Editable ALV Grid

Hi all,
I am trying to create and editable ALV grid using the REUSE ALV FM.
On the grid after changing a value, if I press enter key the pai is not triggered. I have tried the various example programs (BCALV*) but could not find anything relevant.
Basically I need similar functionality to normal module pool programming as in validations on screen done when enter key is pressed after screen entry.
Is it possible to capture the Enter keypress on the ALV grid?

Hello Preet
I can only tell you how I would solve this using the ALV grid control (CL_GUI_ALV_GRID) because I have abandoned using ALV function modules.
The problem with running through PAI is whether the focus (i.e. the cursor) is still on the control or already on the (surrounding) main program. If the control has the focus, you do not run through PAI.
I would add a "Refresh" button to the toolbar of the ALV list. Normally, this button is already there or you only have to make it visible.
When the user pushes this button you catch the corresponding user-command and call the CHECK_DATA_CHANGED method to see if values have been changed on the editable grid. If so, the previous method will fire event DATA_CHANGED.
Now, in the event handler method (e.g. HANDLE_DATA_CHANGED) you receive as input a data change object (CL_ALV_CHANGED_DATA_PROTOCOL). This object contains all changed values. These values you will need to make your checks.
I assume that the logic will be similar using ALV function modules.

Uwe

Capturing Enter Key Press

Hi
Is there a way where we can capture the Enter Key press of the Keyboard and call an event on the Enter Key Press??
For fields such as input field there is onEnter field where an event can be called, but we have a requirement where in we need to call an event on click of enter key, irrespective of where the focus on the page is on.
Any inpus on this will be helpful.

Capture desktop key event to control my screen capture app

I want to write a screen capture program to capture screen when I am playing fullscreen game or other desktop window application. But the java screen capture program can only receive key or mouse event when it is focused. So how do I capture key event when I am focusing other app or fullscreen app?
Do I have to use JNI and call some OS specific API. My target OS is WinXP. Help or suggestions are appreciated!!

Hi All,
I was wondering if there is a way to capture the top-most
window or dialog box. This is something that will
generally be running outside of the JVM....We,
as programmers, need a Rectangle instance that describes the area
of interest to be captured (i.e., location and size).
Thus, a routine that interfaces to the Native windowing system (Toolkit?)
might look something like:
Rectangle rect = tk.getRectangleForTopMostComponent();
Does anything like this exist?
Thanks!

Capture enter key press in h:inputtext

hi,
i have a h:inputText component in my jsf page. i need to capture the enter key pressed for this component. how can this be done.
thanks in advance.

You can use Javascript for this. In the onkeypress event, check if the keycode is 13 (the enter key) and handle accordingly.
onkeypress="if (event.keyCode == 13) alert('Enter pressed!');"

Capturing ENTER key in WD4A

Hi all,
I m getting an input from the user in an Inputfield. I also have a table with two columns.
The textfield is used to perform wildcard search (filter) for the table. That is, if i give a character like 'A', then the records which start with the character 'A' must be shown in the table when i press teh ENTER key..
I have got this outptu when i click a button. But i want to get the same output, when i give 'A' and press ENTER key..
How to acheive the same in WD4A?
Regards,
Shanthi

in the Onactionact,method in the Methods tab , write the same piece of code , which u r writting in the Button
u wud be able to do it nw

Handling Enter key event in JTable

Hi...
This is particularly for the user "VIRAVAN"...
I have followed your method ,and got results too.. but the
processKeyBinding(.. method is called 4 times,same problem addressed by you before, but I didn't understood it...
Please help me...
Here is my code...
protected boolean processKeyBinding(KeyStroke ks, KeyEvent e,int condition, boolean pressed)
System.out.println("Wait");
if (ks == KeyStroke.getKeyStroke(KeyEvent.VK_ENTER,0))
int selRow = getSelectedRow();
int rowCount = getRowCount();
int selCol = getSelectedColumn();
String val =(String)getValueAt(selRow,selCol);
boolean b= getCellEditor(selRow,selCol).stopCellEditing();
System.out.println(b);
System.out.println(rowCount-1 + " "+ selRow + " " + getSelectedColumn());
if((!val.equals("")) && selRow==rowCount-1)
System.out.println(rowCount-1 + " "+ getSelectedRow()+ " " + getSelectedColumn());
blank1 = new String[columns];
for(int p=0;p<columns;p++)
blank1[p]="";
Diary.this.datarows.addElement(blank1);
// dataModel.fireTableStructureChanged();
//dataModel.fireTableDataChanged();
Diary.this.dataModel.fireTableChanged(null);
else if(ks ==KeyStroke.getKeyStroke(KeyEvent.VK_1,0))
System.out.println("One One One One ");
return super.processKeyBinding(ks,e,condition,pressed);

It's been a while since I looked at the code, but essentially there are three key event types:
1) key pressed,
2) key typed,
3) key released.
So I would expect the processKeyBind to see all three of them. However, ks==KeyStroke.getKeyStroke(KeyEvent.VK_ENTER,0) is true only when a key typed event is detected (the other types can be ignored by passing it up the food chain where they will eventually be consumed). Now...., if I understand you correctly, you want to terminate edit on the present of Enter key, right? Here is how I'd suggest you do:
   protected boolean processKeyBinding(KeyStroke ks, KeyEvent e, int condition, boolean pressed) {
      if (isEditing()) {
         Component editorComponent=getEditorComponent();
         editorComponent.stopCellEditing();
         return true;
      return super.processKeyBinding(ks,e,condition,pressed);
   }Ok.... now, it appears that you want to do something else also... i.e., add a new row to the table if the editing row is the last row and the editing column is the last column of the last row. You can't do that in the same thread (i.e., you must wait until the update in the current thread is completed). So, what you must do is use the SwingUtilities.InvokeLater, like this:
   protected boolean processKeyBinding(KeyStroke ks, KeyEvent e, int condition, boolean pressed) {
      if (isEditing()) {
         Component editorComponent=getEditorComponent();
         editorComponent.stopCellEditing();
         if (getEditingRow()+1==getRowCount() && getEditingColumn()+1==getColumnCount()) {
            SwingUtilities.invokeLater(new Runnable() {
               public void run() {
// put the code for adding new row here
         return true;
      return super.processKeyBinding(ks,e,condition,pressed);
   }OK?
;o)
V.V.
PS: posted code is untest but should work!
