Register Enter KeyboardAction to a TextField

hi,
I am registering enter keyboard action to a textfield as following which is not working
Action done = new KeysAction("done",this);
amountTextField.addActionListener(this);
amountTextField.registerKeyboardAction(done,KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0),JComponent.WHEN_IN_FOCUSED_WINDOW);
class KeysAction extends AbstractAction
String ac;
public KeysAction(String name,Component comp)
ac=name;
target = comp;
public void actionPerformed(ActionEvent evt)
if (ac.compareToIgnoreCase("done")==0)
System.out.println("Enter Key Pressed in Amount Field ");
private Component target;
please help

This thread uses InputMap/ActionMap classes to add an Action to a KeyStroke:

Using Enter key on the TextField

How to complete filling of the text to a TextField after pressing key "Enter"?

pressing enter causes any ActionListener objects to be notified. checkout the java tutorial to see how to do this:
http://java.sun.com/docs/books/tutorial/uiswing/components/textfield.html
(note this actually uses a JTextField but it's pretty much the same with TextField)

Enter key in jato:textField crashes ViewBean

I have a jato:textField in a very simple JSP/ViewBean which was migrated
from NetDynamics with the iMT tool and then hand-modified to work under the
JATO framework.
If I click Enter in the textField, the page crashes with ServletException
"The request was not handled by the specified handler". It doesn't give a
line number. Using an IDE debugger (JBuilder) I see that a forwardTo()
method has been invoked.
Other pages don't react to the enter key like this. They beep the
client. Exactly what I want. Where do I look for trouble?

Prevent User From Entering Characters In A TextField

Does anyone know how to prevent certain kinds of letters or symbols from being entered into a textfield? Something that prevents the user from typing a minus sign or the letter Q.

You can also use KeyListener. You can also search the forum as this question has been asked numerous times.

Re-register / Enter Unlock Code Every Time PS Album is Launched

Hi there,
I have a client with Adobe Photoshop Album Starter Edition 3.2 bringing up the registration screen each time it's launched. The registration has been completed several times, and each time he did receive his unlock code. If you put the unlock code in, it is accepted no problem. However, next time Album is launched, it comes back up with the registration screen. Thanks in advance for any suggestions!

Andrea:
I had the same problem, registering again every time I opened the program, even though the unlock code had been accepted before.
I was going to uninstall it.
I went to "Add or Remove Programs", clicked "Adobe Photoshop Album Starter Edition 3.2"(the first of two entries), clicked "Change/Remove", and in the box that appeared was a choice to remove or repair. OK, what have I got to lose, so I chose repair. I then started the program, installed my unlock code one more time, and have been free of the problem since.
Hope this will work for you.

To fix the length of a textfield for user to enter date

hi,
i need to display a textfield for user to enter the date in the format MM/DD/YY.With the slash in between present and fixed and the possibility of entering only 2 digit figures for the month,day n' year.I am using JTextField .how can i acheive that pls help.

You must design you own document where you will manage the text that will be entered/displayed in your textfield
here's a sample of the code I use to do this:
import javax.swing.JTextField;
import java.io.*;
import javax.swing.*;
import javax.swing.text.*;
import java.awt.*;
import java.awt.event.*;
public class MaskedTextField extends JTextField
private String initStr;
public MaskedTextField (String mask, String initStr)
super();
setDocument(new MaskedDocument(initStr, mask, this));
setText(initStr);
this.initStr = initStr;
this.addMouseListener(new java.awt.event.MouseAdapter()
public void mouseClicked(MouseEvent m)
this_mouseClicked(m);
private void this_mouseClicked(MouseEvent m)
if (getText().equals(initStr)) setCaretPosition(0);
class MaskedDocument extends PlainDocument
String mask;
String initStr;
JTextField tf;
public MaskedDocument(String initStr, String mask,
MaskedTextField container)
this.mask = mask;
this.initStr = initStr;
tf = container;
void replace(int offset, char ch, AttributeSet a)
throws BadLocationException
super.remove(offset,1);
if (capitalised) super.insertString(offset,
String.valueOf(ch).toUpperCase(),a);
else super.insertString(offset, "" + ch, a);
public void remove(int offs, int len) throws BadLocationException
if (len==0)
return;
// Remove current contents
super.remove(offs, len);
// Replace the removed part by init string
super.insertString(offs,initStr.substring(offs,offs+len),
getAttributeContext().getEmptySet());
tf.setCaretPosition(offs);
public void insertString(int offset, String str, AttributeSet a)
throws BadLocationException
if ((offset==0) && str.equals(initStr))
// Initialisation of text field
super.insertString(offset,str,a);
return;
if (str.length()==0)
super.insertString(offset,str,a);
return;
for (int i=0;i<str.length();i++)
while ((offset+i) < mask.length())
if (mask.charAt(offset+i)=='-')
// Skip fixed parts
offset++;
else
// Check if character is allowed according to mask
if (str.charAt(i) != this.initStr.charAt(i))
switch (mask.charAt(offset+i))
case 'D': // Only digitis allowed
if (!Character.isDigit(str.charAt(i)))
return;
break;
case 'C': // Only alphabetic characters allowed
if (!Character.isLetter(str.charAt(i)))
return;
break;
case 'A': // Only letters or digits characters allowed
if (!Character.isLetterOrDigit(str.charAt(i)))
return;
break;
replace(offset+i, str.charAt(i),a);
break;
else
i++;
offset--;
// Skip over "fixed" characters
offset += str.length();
while ((offset<mask.length()) && (mask.charAt(offset)=='-'))
offset++;
if (offset<mask.length())
tf.setCaretPosition(offset);
if (offset == mask.length()) tf.setCaretPosition(offset);

Checking If TextField Has Been Entered

Basic, I know. Sorry, but I can't work it out.
I need to check if a user has entered text in a textfield, if the user has entered text then I'll use it. If they haven't, I'll ignore it.
I've been looking through the API for an isNull or isEmpty method, but can't seem to find anything.
Can anyone help

How abouttextArea.getText();If you want to check text on the text area gaining/losing focus, try:textArea.addFocusListener(new FocusListener(){
     public void focusGained(FocusEvent event){
          System.out.println("Gained focus: text on entry is " + ((JTextArea)event.getComponent()).getText());
     public void focusLost(FocusEvent event){
          System.out.println("Lost focus: text on leaving is " + ((JTextArea)event.getComponent()).getText());
textArea.addKeyListener(new KeyListener(){
     public void keyTyped(KeyEvent event){
          System.out.println("Typed: " + event.getKeyChar());
});Hope this helps.

Entering numbers into textfield

Hi,
is there any way of entering numbers into a textfield whereby the user doesn't have to toggel the device inorder to produce said numbers- a bit like a calculator application; any suggestions welcome
James

Sure, it is very easy.
Read about TextField Input Constraints.
They are
ANY
EMAILADDR
NUMERIC
PHONENUMBER
URL
DECIMALYou need NUMERIC or DECIMAL.
You can set them in two way
1. public void setConstraints(int constraints)2. Pass to TextField constructor:
TextField(String label, String text, int maxSize, int constraints)e.g.
TextField myTextField = new TextField("myLabel", "myText", 32, TextField.NUMERIC)Read also about Input Modes. It can be also useful.

Enter/Return in Textfield or other widgets

I have the problem that my Plugin crashes if i enter something in a textfield (TextEditBoxWidget) or Dropdownlist (DropDownListWidget) and press Enter to submit the form instead of using the Button. How can i avoid this? The Update Method of DialogObserver is not entered.

Sorry i posted this in wrong category. Could you put it into

Why am I having to re-enter my registration information each time I open the application?

Hi All,
I purchased Apeture with my Macbook three years ago and have just recently decided to utilize it. EVERY time I open the program I'm prompted to enter my registration information. I'm entering the info each time, but would love not to! (I registered the product in an attempt to make the dialog box go away to no avail.) Any ideas?

First of all, are you using an administrator account, when you are entering the serial number? Aperture needs to write the information to the system library, not the user library. Try to log in from an admin account while entering the serial number. If that does not help, you may have a corrupted "ProAppSystemID" file or Aperture cannot write to the System Library.
First check, if you still have an old file "ProAppSystemID" in your System Library.
Quit Aperture.
Go to your MacintoshHD and open the folder "Library", then "Application Support", then "ProApps".
Remove the File "ProAppsSystemID" to the Desktop, if it exist and restart Aperture.
Reenter your serial number, hopefully for the last time.
Sometimes Aperture writes this file to a temporary directory, when it cannot write to the Library. If the above does not work, look at the temporary directory /tmp
Use the Finder's "Go" menu
Go > Got to folder and enter /tmp into the textfield. If you see the file there, move it to its proper location.
Check the permission on the folder "Library", then "Application Support", then "ProApps". You (as admin) need to have read/write access to all flders along the path.

Unable to get the value from the textfield in valueChangeEvent

Hi,
I have created one custom textField by extending the CoreInputText. Now i have attched default ValueChangeListener to it. I am using this textField in my application.
Now i type some thing and do a focus lost, the value change listener get called. i want to validate the value entered. In that listener method if i take the getSource() from ValueChnageEvent object and do a getValue() I am getting the entered value.
My problem is that if i do a getValue() of the textField i am not gettting the value entered.
How can i get the entered value from the textfield.? Is there any method to notify to do this?
Thanks in advance.

Hi,
I tried to the value from coreInputText also. If i check the getValue method of the component, i am getting the last updated value. I have debug the FlowPhaseListsner also. And i found that this listener is calling before the updateModel phase. Due to that i am not getting the value from the Field.

Problem reading data from textField?

I have a problem in my program I'm currently doing.
I have a textArea and a textField in a container.
Inside the textArea will be displayed some questions which require user to give answers to in the textField.
When user types something in the textField and presses enter, an actionListener will trigger and take in String.
My problem is how do you wait for the user to type something in the textField?
thanks

HT3805 Aperture keeps asking me to register. I register and it runs fine. But then when I rerun Aperture, it asks for me to register again.

This is a replacement serial number that I am typing in. I got it from a technician and was told to use it rather than my old serial number. I would appreciate some help on this.

First of all, are you entering your serial number from an administrator account, or from a plain user account? If you enter the serial number as a regular user, Aperture cannot write the registration to the system library, and you will have to enter it again, when you log in again.
Also, you may have a corrupted "ProAppSystemID" file or Aperture cannot write to the System Library.
To stop Aperture asking for the serial number, first check, if you still have an old file "ProAppSystemID" in your System Library.
Quit Aperture.
Go to your MacintoshHD and open the folder "Library", then "Application Support", then "ProApps".
Remove the File "ProAppsSystemID" to the Desktop, if it exist and restart Aperture.
Reenter your serial number, hopefully for the last time.
Sometimes Aperture writes this file to a temporary directory, when it cannot write to the Library. If the above does not work, look at the temporary directory /tmp
