JMenu ACCELERATOR_KEY "control I"

I'm adding some accelerators to my application and I've spent ages trying to make it work
only to find that the problem seems to be my choice of accelerator !
"control O" works.
"control I" shows up in the menu but doesn't actually do anything.
It's not related to the strings I used because
KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_I, java.awt.event.InputEvent.CTRL_MASK );fails too !
Can anyone shed some light on this ?

Believe it or not I did try searching on various different flavours of keywords but I didn't find
the article that you did !
Thanks for your help - perhaps if you can give me the exact string you searched for it might
help me in the future !?!?

JCheckBox to JMenu (no ACCELERATOR_KEY shown)

Hi,
i have a ActionClass created with this value:
putValue(ACCELERATOR_KEY, KeyStroke.getKeyStroke('S', Event.CTRL_MASK, false));If i add this action to JMenu, the accelerator info is shown in the menu and can be used:
boardMenu.add(showSolutionAction);But if create a JCheckbox with my ActionClass, the accelerator isn't shown and isn't working.
JCheckBox solutionCheckbox = new JCheckBox(showSolutionAction);
boardMenu.add(solutionCheckbox);I'm working with Java6b2, but i think it's the same with Java5.
I think it's an unwanted behavior. What do you think?
Does someone knows a workaround?
Cheers,
Ingo

I think it's an unwanted behavior. What do you think? I think its desireable behaviour.
When using a JCheckBox the user already has a visible clue on how to invoke the button if you use a mnemonic. There is no visual clue if you set an accelerator, so how does the user know what the accelerator is.
Does someone knows a workaround?Two solutions:
a) JMenuItem overrides the configurePropertiesFromAction() method to specifically set the accelerator. So you can extend JCheckBox to add the same logic:
    protected void configurePropertiesFromAction(Action a) {
        super.configurePropertiesFromAction(a);
        KeyStroke ks = (a==null) ? null :
            (KeyStroke)a.getValue(Action.ACCELERATOR_KEY);
        setAccelerator(ks==null ? null : ks);
    }b) Set the accelerator yourself when you create the check box:
JCheckBox checkbox = new JCheckBox(action);
checkbox.setAccelerator( (KeyStroke)action.getValue(Action.ACCELERATOR_KEY) );

How to set JMenu/JMenuItem.accelerator property in Inspector

How do you set an accelerator key through the accelerator
property in the inspector for a JMenu or JMenuItem object? The
list box contains one item, "<none>". Does one have to create
some special keyboard shotcut objects that then will be added to
the list?
Where can one find documentation for the Swing classes, as far
as I can see it's not included?
Thanks.

I know how to do it in the code but it must be possible to do it
from the Inspector since the property is listed there?
Thanks.

Did you convert your html code to call the sun VM instead of the default browser VM ?
Use the HtmlConverter.exe to do this passing the html file in argument.

How do I force JMenu not to open but to forward the click

Hi!
I'm working on a swing application. To control it I use a JMenuBar as a container which contains several JMenu items. I do not use JMenuItems at all!
When I click on such a JMenu the click is forwarded using a MenuListener - that all works without any problem.
When I click on one of those items it is activated just like I would use a submenu with it. Just like clicking on "File" at regular applications and moving the mouse in a horizontal way I can just by moving the mouse using the other JMenu's. I don't want that, I just want to click them without them to become marked or activated in a way!
How can I change that?
Thank you in advance!

Just like
clicking on "File" at regular applications and moving
the mouse in a horizontal way I can just by moving
the mouse using the other JMenu's. I'm not sure I understand just exactly what you mean by this. Do you mean that when you click on the File menu,
and by moving the mouse across the menu bar, the other menus are activated (focus given to the menu over
which the mouse hovers)?
Is this what you are referring to?

Adding ActionListener to JMenu

Is it possible to add actionListener to Jmenu object
for example File, Format, Exit these are Menus added in the menuBar not menu items
on clicking the Exit the frame shuld get closed.
For detecting the action clicked on the Menu shall i use actionListener?
I have tried using MenuListener its getting invoked on selection
I dont want it on selection , I want the frame to be displayed only on clicking that menu.

Alas, whilst a JMenu is-a JMenuItem (the Composite Pattern at work), it doesn't function entriely like on,
and registering ActionListeners with a JMenu doesn't work. Try MenuListener:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class ActionExample {
    public static void main(String[] args) {
        Action sample = new SampleAction();
        JMenu menu = new JMenu("Menu");
        menu.setMnemonic(KeyEvent.VK_M);
        menu.add(sample);
        menu.addMenuListener(new SampleMenuListener());
        JToolBar tb = new JToolBar();
        tb.add(sample);
        JTextField field = new JTextField(10);
        field.setAction(sample);
        JFrame f = new JFrame("ActionExample");
        JMenuBar mb = new JMenuBar();
        mb.add(menu);
        f.setJMenuBar(mb);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(tb, BorderLayout.NORTH);
        f.getContentPane().add(field, BorderLayout.SOUTH);
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
class SampleMenuListener implements MenuListener {
    public void menuSelected(MenuEvent e) {
        System.out.println("menuSelected");
    public void menuDeselected(MenuEvent e) {
        System.out.println("menuDeelected");
    public void menuCanceled(MenuEvent e) {
        System.out.println("menuCanceled");
class SampleAction extends AbstractAction {
    public SampleAction() {
        super("Sample");
        putValue(ACCELERATOR_KEY, KeyStroke.getKeyStroke("alt S"));
        putValue(MNEMONIC_KEY, new Integer(KeyEvent.VK_S));
        putValue(SHORT_DESCRIPTION, "Just a sample action");
    public void actionPerformed(ActionEvent evt) {
        System.out.println("sample...");
}

JMenu, passing mnemonic/ keyevent

Hi
Im building a JMenu but as it has many items im using a function to make each JMenuItem. The function calls the JMenu constructor with the text and the image to be used. I want to pass the mnemonic but can't work out how to do it.
//example of function call
menu1.add(add("myText","myPic.gif"));
//what i need to send to function
menuItem.setMnemonic(KeyEvent.VK_T);also is it possible to do the same with accelerators, ie pass this info to the function
menuItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_T, ActionEvent.ALT_MASK));thanks

Okay, it's still not clear to me what you're trying it write, but is it a method like the following?
import java.awt.event.*;
import java.net.*;
import javax.swing.*;
public class Blank implements ActionListener {
    static JMenuItem add(JMenu menu, ActionListener al, String text, int mnemonic, String keyStoke, String iconURL) {
        JMenuItem item = new JMenuItem(text);
        if (al != null)
            item.addActionListener(al);
        if (mnemonic != 0)
            item.setMnemonic(mnemonic);
        if (keyStoke != null)
            item.setAccelerator(KeyStroke.getKeyStroke(keyStoke));
        try {
            if (iconURL != null)
                item.setIcon(new ImageIcon(new URL(iconURL)));
        } catch (MalformedURLException e) {
            e.printStackTrace();
        return menu.add(item);
    public void actionPerformed(ActionEvent evt) {
        System.out.println("your code here");
    public static void main(String[] args) {
        JMenuBar mb = new JMenuBar();
        JMenu menu = new JMenu("menu");
        add(menu, new Blank(), "blank", KeyEvent.VK_K, "control B", "http://forum.java.sun.com/im/ic_eye.gif");
        add(menu, null, "zip", 0, null, null);
        mb.add(menu);
        final JFrame f = new JFrame("Blank");
        f.setJMenuBar(mb);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.pack();
        SwingUtilities.invokeLater(new Runnable(){
            public void run() {
                f.setLocationRelativeTo(null);
                f.setVisible(true);
}

JMenu.setDelay()

Has anyone used JMenu.setDelay() ?
The documentation says: "Sets the suggested delay before the menu's PopupMenu is popped up or down." and then goes on to talk about different UI implementations. We are using a derivitive of the metal look & feel on Windows 2000 and XP.
I was hoping that this control would also slow down the opening and closing of submenus. I do seem to get an open delay when I move the mouse down the parent menu (although I don't appear to be able to set the duration of that delay), but the submenu closes immediately my mouse passes beyond the current parent item.

I was hoping that this control would also slow down the opening and closing of submenus.When the documentation says "pop up or down" it means that when the menu is displayed it will normally "pop down", but if there is not enough room at the bottom of the frame then it will "pop up". It is not referring to the closing of the menu. Therefore the behaviour is working according to the documentation when I tested it.
I do seem to get an open delay when I move the mouse down the
parent menu (although I don't appear to be able to set the duration of that delay), The delay worked fine for me.
I tested using JDK1.4.2 on XP.

JMenu Disappearing into Background

Hi there,
I just have a problem with my JMenu Disappearing into the background after I load an image using JAI. The Menu is there to begin with, but after I open a picture it disappears behind the picture and I cannot seem to find a way to get it to be at the front for further usage.

Enable/Disable JMenu in JFrame on click of button in JInternalFrame

Hello there. Could anybody help me out of the situation?
I am trying to enable/disable JMenu of JFrame on click of a button which is in JInternalFrame.
I want to set JMenu(this is in JFrame).setEnable(true) in ActionPerformed() of JInternalFrame, but JFrame and JInternalFrame are the different classes and I do not know how I can access JMenu in main frame.
How should I write something like mainframe.menu.setEnabled(true) from internal frame?
For JInternalFrame window action, there is JInternalFrameListener, but this is not relevant for my situation because I am trying to control on click of a button.
Can anybody suggest a solution?

// Main Frame
public class MainFrame extends JFrame
     public MainFrame()
          InternalFrame l_int = new InternalFrame(this);
                //try to initiate internal frame like this
     public void activateMenu()
          menuBar.setEnabled(true);
     public static void main(String args[])
          MainFrame mainframe = new MainFrame();
// Internal Frame
public class InternalFrame extends JInternalFrame
     private MainFrame m_mainFrm = null;
     public InternalFrame(MainFrame a_objMainFrame)
          //your own code
          m_mainFrm = a_objMainFrame;
     public void actionPerformed(ActionEvent a_objevent)
if(m_mainFrm != null)
          m_mainFrm.activateMenu();
}try this.. hope this will help you

JMenu inner: how I can?

Hello!
I have a little trouble with inner JMenu.
I must to do a JMenu that contains a few of JMenu that haves a lot of JMenuItem; all components are created at run-time.
For example, the first JMenu (called "FIRST") contains the JMenu 1,2,3,4..
All 1,2,3 use their name as paramether for have a ResultSet that is used for building JMenuItem associated to JMenu 1,2,3...
in picture
FIRST------->1--->JMenuItem 0
|
|--->2--->JMenuItem 1
| |
| -->JMenuItem 1
|
--->3--->etc...
There's the code:
/*connection to db*/
JMenu first=new JMenu();
JMenu second=new JMenu();
ResultSet rs_class=st.executeQuery(...);
/*i have the voices for the first jmenu*/
while(rs_class.next()){
name_class=rs.class.getString(1);
}/*end while for class*/
/*i create the JMenu first using the arraylist classi for remember the element's name*/
for(int i=0;i<classi.size();i++){
name_class=classi.get(i);
first=new JMenu(name_class);
ResultSet rs_metodo=st.executeQuery(...);
while(rs_metodo.next()){
name_method=rs_metodo.getString(1);
metodo.add(name_metodo);
}/*end while JMenu second*/
for(int j=0;j<metodo.size();j++){
nome_metodo=metodo.get(j);
second=new JMenu(name_method);
ResultSet rs_param=st.executeQuery(...);
/*i create the jmenuitem for jmenu second*/
while(rs_param.next()){
String p1=rs_param.getString(1);
JMenuItem mi= new JMenuItem(p1);
second.add(mi);
}/*end while param*/
first.add(second);
}/*end method*/
this.add(first);
}/*end for of class*/
}/*end method for JMenu-Jmenu-JMenuItem*/My problem is that second is not reset on the change of step but in all step him add the new JMenuItem() and him memorize all old JMenuItem.
I want that, in all step, second take only JMenuItem generated in the step and only in this step.
How must I code for have the reset of second JMenu?
Thanks for every feed-back

When a 430EX II is used wirelessly via E-TTL, it can only work in the "slave" mode (it can be an off-camera remote flash, but if it is used on-camera, it cannot work as a "master" to control the "slaves".) Alsok the 430EX II has no radio, so it can only work in "optical" mode.
The 600EX-RT is the flagship flash... it can be "master" or a "slave". It can also work via "radio" or "optical".
So while the 600EX II is versatile, the 430EX II is more restrictive. That means you have to use 430 off-camera and the 600 on-camera as the master.
The ST-E3-RT is _only_ a radio trigger... it cannot trigger a flash optically. The ST-E2 can trigger optically (but not radio).
The 5D III has no built-in trigger. That means if you want to control both the 430 and 600 off-camera, you'd need an ST-E2 to do it.
When I bought my 5D III, I had a 430EX II and a 580EX II. I've since bought a pair of 600EX-RT units and then finally added the ST-E3-RT controller. I no longer use my 430EX II or 580EX II (those are "on loan" to friends. I say "on loan" because I realize I don't need them anymore and so there's really no reason for them to ever return them. At this point, I might as well just call them "gifts".)

Issue in creation of control cycle

Dear Gurus,
During creation of control cycle (LPK1), the fields for source information is not appearing in my system.
I compared control cycle in a different ECC system where source information is appearing.
How can make the screen appear in my ECC system.
Please find the screenshots.
Any pointers will be highly appreciated.
This thread is further to the threads in Production Planning and LE/WM Forum. I could not resolve the issue with the threads.
Hope that I will get any pointer in EWM forum.

Hello Malay,
Can first contact your ABAPer and ensure the bottom screen is not an Screen Enhancement?
If it is a some custom development, your ABAPer can help you on the logic behind it.
Else, Let us know.

IF-statement in Personas that is checking if control is inactive?

Hi,
I have this simple script in screen personas that is clicking the option: "Attachment list". Everything is working great if there is attachments.
If there are no attachments the option is "inactive" or "greyed out". This will result in a script error.
I thought this was going to be an easy fix by adding IF statement to the the script. But howerver I specify the critera for the IF statement the script will always try to click the Attachment list. The condition will simply always be TRUE.
Am I missing something here or is it not possible at this time to script an IF statement that is checking if the control is inactive or similar?
Best Regards,
Oskar Söderlund

There is another way, but it will get a little tricky.
Outside of the transaction IE03 you can check for the existence of attachments for a piece of equipment by looking in table SRGBTBREL. Field TYPEID_A will be "EQUI" and field INSTID_A will be the equipment number, zero-padded on the left to 18 characters long. Use SE16 to look in the table and you'll get the idea.
You could wrap this test in an RFC-enabled ABAP function and call that from your Personas script button. Use the return value from that RFC to decide if attachments exist or not and how the script should respond. Details for how to write such an RFC and call it from a Personas script are in this blog: Calling RFCs from a Personas script.
Like I said, this isn't straightforward and perhaps Personas scripting should include an active/inactive test in addition to the exists/doesn't exist test. Until then, however, there is a way if you don't mind a bit of ABAP programming.

ANY SY-INDEX REFLECT CHANGES WHEN CONTROL BREAK STATEMENT PROCESS

Dear Guru's,
                 I have a requirement where i have to move the values to variable when control break (AT END OF) process. So i want to move the values according to the end of Vendor so for that i want to know is there any sy-index available which reflects changes when Control break (AT end of) process.
LIKE Sy-subrc = 0 when select statement fetches record or sy-tabix is like counter for loop.
Hope to get reply soon.
Regards,
Himanshu Rangappa

Hi,
There is no system Fields for it.
But your requirement can be done with 'AT NEW' and 'AT END' statement.
Refer this sample example,
loop at otab.
    at new module.
      move otab-module to otab2-module.
    ENDAT.
      at END OF effort.
      sum.               "Do your calculations here
      move otab-count to otab2-count.
      append otab2.
    endat.
endloop.
