Cursor becomes invisible in JTextField after using default button

In my application there is an update screen (JPanel). I am using default button in that panel. The input field is a normal JTextField. When the update is over the cursor goes back to the input JTextField.
     Now my problem is that when I carry out update with mouse, the cursor is correctly placed into the input JTextField and is visible after the update is over. On the other hand, if I carry out the same update operation using default button (using keyboard), the cursor gets placed correctly in the input JTextfield column, but becomes invisible. If I minimize and then again maximize the window, the cursor appears back. What am I missing ? Note that I am using component.requestFocusInWindow() to get focus back to the input JTextField.

Trying to re-add UPDATE and DELETE default buttons to a form

I created a maintenance form by copying a form I use for inserting rows into a table. I deleted most of the form's default buttons.
Now I'm trying to add the UPDATE and DELETE buttons to the cloned maintenance form, with no luck. When I look at the source
for another maintenance form, the update button shows the following code:
<INPUT TYPE="BUTTON" NAME="FORM_TEST1_MAINTENANCE.DEFAULT.UPDATE_TOP.01" VALUE="Update" onClick="if (validateWWVM281(this.form)) do_event(this.form,this.name,1,'ON_CLICK','');">
The newly inserted UPDATE button's code is:
<INPUT TYPE="BUTTON" NAME="FORM_TEST2_MAINTENANCE.DEFAULT.UPDATE_TOP.01" VALUE="Update" onClick=" do_event(this.form,this.name,1,'ON_CLICK','');">
So...... I added the code "if (validateWWVM281(this.form))" (no quotes) to the button's ONCLICK area. The source code for the form now looks like this:
<INPUT TYPE="BUTTON" NAME="FORM_TEST2_MAINTENANCE.DEFAULT.UPDATE_TOP.01" VALUE="Update" onClick="if (validateWWVM281(this.form)); do_event(this.form,this.name,1,'ON_CLICK','');">
Note the semicolon after the IF statement.
Bottom line.... if I wish to add a button to a form to replicate teh functions of a default button, how do I do this?

In the PL/SQL Button Event Handler for UPDATE button select 'Update' and write the following code:
doupdate;
and for DELETE button select 'Delete' and write
dodelete;
You don't need any code in the OnClick for these buttons.
Hope this helps.

A default button question

mavens,
I'm trying to implement the following:
when the script first runs, a certain dialog box does not have a default button but upon subsequent runs the selected button comes up as default.
It is easy to implement except the initial setting. "default button 0" or "default button no" brings up "no such button" error messages upon compliation.
of course I could have a dialog step with no default buttons defined that is accessed only on first run and an identical step with a "default button (myvariable)" on any subsequent runs but I'm trying to make it neat.
can it be done or not?
TIA

Hello
Here's another techinque.
This may help when you have several display dialog calls to control but will be least effective when you have only one.
Cheers,
H
-- SCRIPT
main()
on main()
(* Invoking original osax.*)
display dialog "original" buttons {"Cancel", "OK"} default button 2 with icon 1 giving up after 2
(* Invoking customized osax (defined in a script object to restrict its scope)
Note that 'giving up after' parameter is ignored, for it's not implemented in the overriding handler. *)
tell my ddhook1 to ¬
display dialog "customized" buttons {"Cancel", "OK"} default button 0 with icon 1 giving up after 2
end main

Default button being clicked multiple times when enter key is pressed

Hello,
There seems to be a strange difference in how the default button behaves in JRE 1.4.X versus 1.3.X.
In 1.3.X, when the enter key was pressed, the default button would be "pressed down" when the key was pressed, but wouldn't be fully clicked until the enter key was released. This means that only one event would be fired, even if the enter key was held down for a long time.
In 1.4.X however, if the enter key is pressed and held for more than a second, then the default button is clicked multiple times until the enter key is released.
Consider the following code (which is just a dialog with a button on it):
public class SimpleDialog extends JDialog implements java.awt.event.ActionListener
private JButton jButton1 = new JButton("button");
public SimpleDialog()
this.getContentPane().add(jButton1);
this.getRootPane().setDefaultButton(jButton1);
jButton1.addActionListener(this);
this.pack();
public void actionPerformed(ActionEvent e)
if (e.getSource() == jButton1)
System.out.println("button pressed");
public static void main(String[] args)
new SimpleDialog().show();
When you compile and run this code under 1.3.1, and hold the enter key down for 10 seconds, you will only see one print line statement.
However, if you compile and run this code under 1.4.1, and then hold the enter key down for 10 seconds, you will see about 100 print line statements.
Is this a bug in 1.4.X or was this desired functionality (e.g. was it fixing some other bug)?
Does anyone know how I can make it behave the "old way" (when the default button was only clicked once)?
Thanks in advance if you have any advice.
Dave

Hello all,
I think I have found a solution. The behaviour of the how the default button is triggered is contained withing the RootPaneUI. So, if I override the default RootPaneUI used by the UIDefaults with my own RootPaneUI, I can define that behaviour for myself.
Here is my simple dialog with a button and a textfield (when the focus is NOT on the button, and the enter key is pressed, I don't want the actionPerformed method to be called until the enter key is released):
package focustests;
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.util.*;
public class SimpleDialog extends JDialog implements java.awt.event.ActionListener
private JButton jButton1 = new JButton("button");
public SimpleDialog()
this.getContentPane().add(new JTextField("a text field"), BorderLayout.NORTH);
this.getContentPane().add(jButton1, BorderLayout.SOUTH);
this.getRootPane().setDefaultButton(jButton1);
jButton1.addActionListener(this);
this.pack();
public void actionPerformed(ActionEvent e)
if (e.getSource() == jButton1)
System.out.println("button pressed");
public static void main(String[] args)
javax.swing.UIManager.getDefaults().put("RootPaneUI", "focustests.MyRootPaneUI");
new SimpleDialog().show();
and the MyRootPaneUI class controls the behaviour for how the default button is handled:
package focustests;
import javax.swing.*;
* Since we are using the Windows look and feel in our product, we should extend from the
* Windows laf RootPaneUI
public class MyRootPaneUI extends com.sun.java.swing.plaf.windows.WindowsRootPaneUI
private final static MyRootPaneUI myRootPaneUI = new MyRootPaneUI();
public static javax.swing.plaf.ComponentUI createUI(JComponent c) {
return myRootPaneUI;
protected void installKeyboardActions(JRootPane root) {
super.installKeyboardActions(root);
InputMap km = SwingUtilities.getUIInputMap(root,
JComponent.WHEN_IN_FOCUSED_WINDOW);
if (km == null) {
km = new javax.swing.plaf.InputMapUIResource();
SwingUtilities.replaceUIInputMap(root,
JComponent.WHEN_IN_FOCUSED_WINDOW, km);
//when the Enter key is pressed (with no modifiers), trigger a "pressed" event
km.put(KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_ENTER,
0, false), "pressed");
//when the Enter key is released (with no modifiers), trigger a "release" event
km.put(KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_ENTER,
0, true), "released");
ActionMap am = SwingUtilities.getUIActionMap(root);
if (am == null) {
am = new javax.swing.plaf.ActionMapUIResource();
SwingUtilities.replaceUIActionMap(root, am);
am.put("press", new HoldDefaultButtonAction(root, true));
am.put("release", new HoldDefaultButtonAction(root, false));
* This is a copy of the static nested class DefaultAction which was
* contained in the JRootPane class in Java 1.3.1. Since we are
* using Java 1.4.1, and we don't like the way the new JRE handles
* the default button, we will replace it with the old (1.3.1) way of
* doing things.
static class HoldDefaultButtonAction extends AbstractAction {
JRootPane root;
boolean press;
HoldDefaultButtonAction(JRootPane root, boolean press) {
this.root = root;
this.press = press;
public void actionPerformed(java.awt.event.ActionEvent e) {
JButton owner = root.getDefaultButton();
if (owner != null && SwingUtilities.getRootPane(owner) == root) {
ButtonModel model = owner.getModel();
if (press) {
model.setArmed(true);
model.setPressed(true);
} else {
model.setPressed(false);
public boolean isEnabled() {
JButton owner = root.getDefaultButton();
return (owner != null && owner.getModel().isEnabled());
This seems to work. Does anyone have any comments on this solution?
Tjacobs, I still don't see how adding a key listeners or overriding the processKeyEvent method on my button would help. The button won't receive the key event unless the focus is on the button. There is no method "enableEvents(...)" in the AWTEventMulticaster. Perhaps you have some code examples? Thanks anyway for your help.
Dave

Default Button: switched to last focussed, but want Windows behavior, how?

In a JDialog, if I add components and set one to be the default button, plus
use the Windows L&F, I expect the Windows L&F behavior, that is, as long
as I tab along buttons, an Enter will activate a button if it has focus, but if I
tab to another component, the desired default button should be visually marked (darker edge)
and an Enter should activate it.
In Plugin's JRE 1.3.1, this is not the case. The default button is reset to the last button that had
the keyboard focus.
In a JVM 1.2.2, the same code produced the expected result!
The bug db listed a few solutions, one of them was to use a Focus Manager to
track focus and then "manually" reset the default button each time the focus is not on a button.
Anyone out there with a more details on this solution?
Or perhaps, there is a better solution than tracking focus events manually?
Sylvia

Found a solution myself, which at least works for windows l&f:
make all buttons non-default capable (setDefaultCapable(false)), except for the one button, that is to be the default button. This has the unfortunate effect, that a non-default button, which has input focus, does not react to to ENTER, but the ENTER is sent to the default button instead.
So must add a keyboard action to handle the ENTER:
KeyStroke keyStroke = KeyStroke.getKeyStroke ("ENTER");
ActionListener action = new ActionListener(){
public void actionPerformed() {getMyButton().doClick();}};
getMyButton().registerKeyboardAction (action, keyStroke, WHEN_FOCUSED);
That did it for my case.

RE: [iPlanet-JATO] image button handling

Hi Todd,
from what I have seen so far on the Project they are just buttons on
the page.
In the interim, I modified RequestHandlingViewBase.acceptsRequest() to
handle the matching of parameter and command child names.
from
if (request.getParameter(commands)!=null)
return getCommandChildNames()[i];
to
if (request.getParameter(commands[i])!=null ||
(request.getParameter(commands[i]+ ".x")!=null ))
return getCommandChildNames()[i];
This fixed the problem with the image buttons in our cases.

Hi Kostas--
I wanted to get some feedback on the known issue of the
handleXXXXRequest method not being fired for buttons which have
images, due to the the browser submitting
the pixel coordinates back to the server like this:
Page1.ImageButton1.x=...
Page1.ImageButton1.y=...
As the ND conversion project we are currently working on heavily uses
image buttons we would like to get and indication if and when a patch
is planned for this.
Our current work around is to remove the src attribute from the JATO
tags in the JSPs.We are currently working on getting this fixed. One question--what is
the
relative type of usage of image buttons in your project? Are they just
buttons on the page (view bean), or do they appear in tiled views as
well?

OK, here's what I'm trying to do: We have, like you said, a menu
page. The pages that it goes to and the number of links are all
variable and read from the database. In NetD we were able to create
URLs in the form
pgXYZ?SPIDERSESSION=abcd
so this is what I'm trying to replicate here. So the URL that works
is
pgContactUs?GXHC_GX_jst=fc7b7e61662d6164&GXHC_gx_session_id_=cc9c6dfa5
601afa7
which I interpreted to be the equivalent of the old Netd way. Our
javascript also loads other frames of the page in the same manner.
And I believe the URL-rewritten frame sources of a frameset look like
this too.
This all worked except for the timeout problem. In theory we could
rewrite all URLs to go to a handler, but that would be...
inconvenient.

Default buttons not defaulting

Hello. I am on the tail end of a DVD project and just begain encountering some unusual behavior with certain menus. This is a multiple-menu, multiple-video clips promotional DVD.
Up to last week, the DVD has been working as expected in the simulator, in DVD Player (from the Video_TS folder and from a formatted disc), and in several set top players. Yesterday, though, in DVD Player from a formatted disc, the menus appear with no buttons visibly defaulted. The menu still behaves, though, as if the default button was selected (ie., if pressing "enter" activates the default button, and pressing an arrow button sends the selected state in the designated direction.) Each video asset returns to its menu with another default button, and these behave in the same way.
I have already double-checked the connections between the buttons, menus, and videos, and they are set the way they have always been.
- Can the preferences in DVDSP get corrupted (like they can in FCP)?
- Can the DVDSP porject file become "bloated" or corrupted from going through too many revisions? If so, is there an easy way to put the current project into a new file?
I expect that some people that view this disc will do so on a Mac, and I would like to clear this up if it is possible. Any ideas?
Thank you!
Listening,

Aaron:
I would try deleting all PAR and MPEG folders that DVDSP created during your authoring (inside the folders where your source files live) and make a clean build without reusing any of the previous VIDEO_TS folders. Probably some file is corrupted. If you want a FCP analogy, is like deleting your render files!
Trashing preferences is a common preocedure . . . but like in FCP, ussually don't resolve problems. But it's like an aspirin, it will don't hurt your system. You can keep a copy of the pref file to restore in case you need.
You could repair permissions and restart . . . just to be sure everything is cleaned in your system.
I would try deleting all PAR and MPEG folders that DVDSP created during your authoring (inside the folders where your source files live) and make a clean build without reusing any of the previous VIDEO_TS folders.
Probably with the specific experience in your problem psot something in the meantime!

Snap mouse pointer to default button doesn't work

Dear Community,
I own a W520 with W7professional. My mouse is the ThinkPad bluetooth Laser Mouse.
In the mouse properties window, I've activated the "Automatically move pointer to the default button in a dialog box" option but unfortunately it seems not working.
Any idea?
Best Regards,

hey calza_mc,
try uninstalling the mouse drivers and reinstall it.
also, do an update on your bluetooth drivers while you're at it

Pointer does not move to the default button in the dialog box

example: when cleaning out trash the pointer does not go to the default button in the dialog box, you have to manually go there.
This happens all the time.

Set default Button and provide a KeyEvent to a component with focus !!!

What is to do ???
I have following program:
public class DefaultButton extends Frame implements ActionListener
     private Button close;
     public DefaultButton()
          super("Default-Button");
          setLayout(null);
          setSize(400, 200);
          setLocation(150, 100);
          setBackground(Color.lightGray);
          addWindowListener(new WindowAdapter()
               public void windowClosing(WindowEvent e)
                    setVisible(false);
                    dispose();
                    System.exit(0);
          // CloseButton
          close = new Button("Close");
          close.addActionListener(this);
          close.setVisible(true);
          close.setSize(100, 30);
          close.setLocation(290, 160);
          add(close);
          setVisible(true);
     public void actionPerformed(ActionEvent e)
          String cmd = e.getActionCommand();
          if (cmd.equals("Close"))
               setVisible(false);
               dispose();
               System.exit(0);
     public static void main(String [] args)
          DefaultButton wnd = new DefaultButton();
}If I click on "Close"-button, the window will be closed. But, if the button "Close" has focus, it schold be possibile to close the window with a press on the Enter-Key? How to do it? How can I provide an KeyEvent to button "Close"?
Tanks for any help.

Hi pitalica!
It is possible using KeyListener:
public class DefaultButton extends Frame implements ActionListener, KeyListener {
close.addKeyListener(this);
public void keyPressed(KeyEvent e) {
if ((e.getSource() instanceof Button)
&& (((Button) e.getSource()).getActionCommand == "Close")) {
int kc = e.getKeyCode();
if (kc == KeyEvent.VK_ENTER) {
performs any action
public void keyTyped(KeyEvent e) {}
public void keyReleased(KeyEvent e) {}
I hope it helps.

Default button in BOV should always be #1

I have a number of Tracks with button overlay in a subtitle stream and Button Highlight activated (cyan/yellow marker).
The buttons are used to change audio stream during playback.
From a menu with 6 buttons I select a Track:
Button 1 = Track 1
Button 2 = Track 2
and so on.
What happens when I play the Track(s) is this:
Track 1 > Button 1 selected
Track 2 > Button 2 selected
Track 3 > Button 3 selected
etc.
Is it possible to always select button #1 when starting to play a Track, no matter which menu button was used?
As it is now, the user gets confused, since the Track is setup to play audio stream 1 in a pre-script (and this works fine).
TIA
Message was edited by: Niklas Wikman

Problem solved. Double-click on the subtitle in the Track and set the Default button in the Button tab in the PI.

Dear partha,
1) You can be able to trace out the location of the button
2) You can be able to move the cursor to that location
3) You can be able to automatically generate a click on that button
Use user32.dll to achieve all this. when u use it in CLN(Call Library Node), u can c functions 4 that.

How to hide default buttons on WD selection screen

Hi Experts,
Is there a way to hide default buttons ( Cancel, Check, Reset, Copy ) on web dynpro selection screen ??
Please let me know how can I achieve this..
Thanks in advance !
Anand

By selection screen do you mean the select-options reusable component? If so, then there is an API of the component that you can call to disable these fields. Use the SET_GLOBAL_OPTIONS method of the select-options API to acomplish this:
data: l_ref_cmp_usage type ref to if_wd_component_usage.
l_ref_cmp_usage =   wd_this->wd_cpuse_select_options( ).
if l_ref_cmp_usage->has_active_component( ) is initial.
    l_ref_cmp_usage->create_component( ).
endif.
wd_this->lv_wd_select_options =
       wd_this->wd_cpifc_select_options( ).
* init the select screen
wd_this->lv_sel_handler =
       wd_this->lv_wd_select_options->init_selection_screen( ).
wd_this->lv_sel_handler->set_global_options(
    EXPORTING
*      i_display_btn_cancel = ABAP_TRUE    " Displays "Cancel" Button
*      i_display_btn_check   = ABAP_TRUE    " Displays "Check" Button
