JTable: how to prevent events?

Hello friends...
Does somebody know how to prevent a JTable to fire events at certain times when selections are made?
In this case, the selection can be made externally to the table, by a lot of objects at the same time. The goal is to fire an event ONLY when I really need it...
ThanX in advance for any help...

Hello again...
ThanX for your answers, I used a mix of both.
I used the method .setValueIsAdjusting() in ListSelectionModel that considers all coming events as one and I used a flag to enable changes.
The problem now is, I get a big array of values the table has to handle. Since it handles it as one unique event, it should be OK. But I fear that if the array is really monstruous, the method .setValueIsAdjusting() enters in "wait" mode (multi threads and all the stuff) and the flag is set to true (changes possible) without changes being made to table... Perhaps, there would be no problem at all...
Is it possible to force .setValueIsAdjusting() to do his job immediately?
ThanX a lot for your time...

How to prevent AT SELECTION-SCREEN event on second Selection Screen

Hi All
I have a program in which I am entering some parameters in a selection screen and also validating them in AT SELECTION-SCREEN events. After validating them the program shows another selection screen in which I have some push-buttons. I have some events on those push-buttons also.
However I am facing a different problem now. When I execute the second selection screen I get the report, and when I click on back button then it again triggers the AT SELECTION SCREEN event of the first selection screen and displays the related messages.
How to prevent this ? Is there any way where I can restrict the execution of selection screen events for a particular selection screen?
Amol

Hi,
    try this logic when Ist selection screen validation
     is done set a flag = 'X' .
      at selection-screen.
      if glag is initial
       *screen validation
           flag = 'X..
      endif.
regards

How to prevent JFileChooser automatically changing to parent directory?

When you show only directories, and click on the dir icons to navigate, and then dont select anything and click OK, it automatically 'cd's to the parent folder.
My application is using the JFileChooser to let the user navigate through folders and certain details of 'foo' files in that folder are displayed in another panel.
So we dont want the chooser automatically changing dir to parent when OK is clicked. How to prevent this behavior?
I considered extending the chooser and looked at the Swing source code but it is hard to tell where the change dir is happening.
thanks,
Anil
To demonstrate this, I took the standard JFileChooserDemo from the Sun tutorial and modified it adding these lines
          // NEW line 45 in constructor
          fc.addPropertyChangeListener((PropertyChangeListener) this);
          fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
      * NEW -
      * @see java.awt.event.ActionListener#actionPerformed(java.awt.event.ActionEvent)
     public void propertyChange(PropertyChangeEvent e) {
          String prop = e.getPropertyName();
          if (JFileChooser.DIRECTORY_CHANGED_PROPERTY.equals(prop)) {
               System.out.println("DIRECTORY_CHANGED_PROPERTY");
               File file = (File) e.getNewValue();

How to prevent re-login when switching in the application between different module in 6.1.1.1.11?

How to prevent re-login when switching in the application between different module in 6.1.1.1.11?
Please help me to figure out this or resolve this issue?

Be sure to check that your Remoting Container service is running. If it is not, restart the service, and if it goes down again, check the event logs.
Make sure that the AuthenticationBridgeService is enabled in your EnvironmentSettings.config, and the remoting container user is configured using the SetupAssistant.
<RemotingContainer>
         <ConfigInfo configChildKey="key">
               <add key="UserID" value="@@VAR:Prodika.RemotingContainer.SysUser@@" />
         </ConfigInfo>
        
         <RemoteServices configChildKey="name">
             <Service
                 name="AuthenticationBridgeService"
                 port="@@VAR:Prodika.AuthenticationBridge.Port@@"
                 isActive="true" />
If the Remoting Container Service fails, please contact Support with details from the event logs.

[2008R2] Prevent event : The shadow copies of volume D: were deleted because the shadow copy storage could not grow in time

During the restore of data using VSS Snapshots it deleted all the snapshots, this event was written in the system log :
The shadow copies of volume D: were deleted because the shadow copy storage could not grow in time. Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied.
It only restored 20 GB of data and there should be plenty of space in the Shadow copy storage
Used Shadow Copy Storage space: 2.692 GB (0%)
Allocated Shadow Copy Storage space: 5.397 GB (0%)
Maximum Shadow Copy Storage space: 694.752 GB (18%)
When there isn't enough space it should start to delete the oldest snapshots to free up additional space, but it deleted
all the snapshots. The problem is the IO but how to prevent this from happening again?

Hi,
Since the shadow copy storage space doesn’t run out, the issue could be due to the Volsnap.sys driver has encountered excessive I/O activity.
You could refet to the article below to resolve the issue. This article is for Windows 2003 but it will also help on Windows 2008 R2 system.

Programmatically change GUI controls/ prevent event firing

Hi,
I often construct GUIs where user input in one control automatically changes other controls.
A (simple) example:
A GUI contains controls A and B. When the user changes control A the value of control B has to be adjusted, and the other way round. So the event handler of A tells B to change its value. An event is fired, and the event handler of B tells A to change its value. An event is fired... and you have an endless event handling loop.
Please believe me, though the example is simple: this happens frequently in real life, too. Since setting Swing controls programmatically most often triggers events, I need a mechanism to prevent event handling loops. What I do so far is
o set a "deaf" flag
o change the control
o the listener gets informed about the change, but since the "deaf" flag is set it does nothing
o reset the "deaf" flag
Another, equally awkward way, is removing event listeners before the change and reattaching them afterwards.
Is there any elegant way to handle this? How do you handle this kind of problem, which can't be too rare in the GUI world (although a rather extensive search with Google did not find much)?
Chris

Personally, I usually choose the same approach as you did, implementing a flag which I'll check when events are fired. If you do this, however, be sure to make the flag volatile, otherwise it might (very rarely) happen that a thread caches the value (even though this points to faulty code on your side, it is well near impossible to debug). I would strongly recomment not to remove and readd the listeners since it will create a lot of overhead and is rather hard to maintain.

Jtable on cell changed event

How can i treat an Jtable on cell changed event, not on value changed

Do you mean cell selection changed? One way is to add a ListSelectionListener to both the table's and the table's ColumnModel's ListSelectionModels. Something likeListSelectionListener lsl = new ListSelectionListener() {
   public void valueChanged(ListSelectionEvent e) {
      System.out.println(e.getSource());
      ListSelectionModel lsm = (ListSelectionModel) e.getSource();
      if (!lsm.getValueIsAdjusting()) {
         System.out.println("Selection changed");
table.getSelectionModel().addListSelectionListener(lsl);
table.getColumnModel().getSelectionModel().addListSelectionListener(lsl);Note that simultaneous change of both row and column will generate two valueChanged events.
If that's not what you wanted to know, ask a better question.

How to prevent window iconified

Hi!
I am wandering how to prevent window
iconified (this - button on the right-top-
corner on the window).
DO_NOTHING_ON_CLOSE works for X button,
any method to stop iconify!
null

You can use the JFrame method "public void processWindowEvent(WindowEvent e)" and when the WindowEvent ID is WINDOW_ICONIFIED, WINDOW_CLOSING or WINDOW_DEACTIVATING or some other event type that you're interested in, you can set the window visible again. Be careful though, if you don't program a way out of this the window will always be on top and you won't be able to perform any other window functions.
Hope this helps.

Hi,
You need to change the default close operation of JDialog or JFrame:

How to prevent B1 from populating the grid with components?

Hello group,
We have customized a form that pops up when user enters a parent item (of a template-type BOM) in the quotation grid. The form displays the component items and lets the user mark which items to "paste" onto the quotation. However, B1 automatically populates the grid with the component items once focus moves away from the item code column.
<b>How to prevent B1 from populating the grid with components <i>while</i> retaining the parent item in the item code column?</b> I've tried trapping the Validate event, etc. with no success.

Instead of setting the parent item up as a template type BOM, you could set up the list of parent/child items on a user table and use this user table to display the items in your pop-up screen. As the parent item would no longer be a template BOM, Business One would no longer automatically popuplate the grid, and you could write your own code to add only the items selected in your pop-up screen into the grid.

How to prevent PO changes in ME22N after Order acknowledgement?

Hi everyone,
        Can anyone tell me how to prevent PO changes (ANY) in ME22N after Order acknowledgement?
        I would like to make it possible without release strategy process or authorizations.
        Do you know some User Exit or Customazing way?
Regards.
Jaime S.

Dear Jaime S,
You can do this by restricting in authorization SHDO and also by marking "changes not possible after release" in Release strategy procedure.
And also you can navigate the menu to, SPRO------>IMG------>Material Management--->Purchasing(OLME)------->Purchase Order---->Define screen Layouts at Document Level---->And go to ME22n And Select the right parameter and in this you can make it display, optional or required entry for the fields.

How to prevent error message for material description in MDG material detail screen, when user click on check action.
Thanks
Sukumar

Hello Sukumar
In IMG activity "Configure Properties of Change Request Step", you can completely deactivate the reuse area checks (but will then loose all other checks of the backend business logic as well).
You can also set the error severity of the checks from Error to Warning (per CR type, not per check).
Or you provide a default value for the material description, e.g. by implementing the BAdI USMD_RULE_SERVICE.
