EVENT USER_COMMAND for CL_GUI_ALV_GRID

Hello All,
We have a program that uses the CL_GUI_ALV_GRID and the events user_command and context_menu_request. The program functions by selecting an option for the context menu on an ALV grid which will then take you to another screen with another ALV grid.
The issue is on the second screen where the user clicks the back button to return to the first ALV Grid. For some reason, the functionality of Method user_command is triggered twice preventing the user from returning to the initial screen. Once when the menu option is selected and again when the Back button on the second screen is selected. If the user clicks the Back button again it will return to the initial ALV grid. We need to have the program go to the initial ALV grid after the Back button is clicked the first time not the second.
Does anyone have any suggestions on how to correct this? Thanks in advance for your help.

Hi John,
maybe this will help you. I had a similar situation.
1.) When you initialize the grid-controls try to set a
unique identifier within the display-variant.
lf_variant TYPE disvariant.
lf_variant-report = ls_report (NOT SY_REPID!)
lf_variant-handle = 'HUGO'....
2.) After leaving the 2. screen clear all handles using
the method hndle->free, free, clear ...
In PAI you can easaly check <if hndle is initial>
or <if not ( hndle is initial )> ....
Hope this will help you

How can I trigger a USER_COMMAND for alv grid "toolbar" ???

Hi,
i have the standard ALV Grid "toolbar" and if i click to the Button "&LOCAL&COPY_ROW" than i want try to make a Refresh to my ALV Table in the Event "afteruser_command"_!!!!
Here is the implementation of my Event *"afteruser_command":*_
METHOD on_after_user_command.
........DATA: ls_stable TYPE lvc_s_stbl.
.....CASE e_ucomm.
.....WHEN '&LOCAL&COPY_ROW'.
........MESSAGE 'LOCAL_COPY_ROW' TYPE 'S' DISPLAY LIKE 'E'.
........ls_stable-row = 'X'.
........ls_stable-col = 'X'.
........CALL METHOD gr_grid_d0100->refresh_table_display
..............EXPORTING
.......................is_stable      = ls_stable
..............EXCEPTIONS
.......................finished       = 1
.......................OTHERS         = 2.
......ENDCASE.
ENDMETHOD.
But it doesnt work.
Is there another function code for the Copy Button????
Thanks
Ersin

Hello Ersin,
the events "after_user_command", "before_user_command" and "user_command" will not be fired when selecting this command!
In my opinion, there is no solution, to fire these events, using this alv-function!
But there is a trick:
1. Register on the event "toolbar" with an own method:
      toolbar_own          for event toolbar of cl_gui_alv_grid
                                   importing e_object
                                          e_interactive,
In this method change the function code of "&LOCAL&COPY_ROW", but don´t change the row of the entry, because the button should appear on the same place in the toolbar:
    field-symbols: <ls_toolbar> type stb_button.
    read table e_object->mt_toolbar with key function = '&LOCAL&COPY_ROW'
                                    assigning <ls_toolbar>.
    if sy-subrc = 0.
      <ls_toolbar>-function = 'COPYROW_OWN'.
    endif.
2. Register on the event "user_command" ( I think, that´s clear ):
      user_cmd_own           for event user_command
                                          of cl_gui_alv_grid
                                          importing e_ucomm,
( don´t forget the set handler-commands for both events:
set handler po_alv_own->user_cmd_own              for po_alv_own.
set handler po_alv_own->toolbar_own               for po_alv_own.     )
3. Now you can react in the method "user_command" on your own function code:
    case e_ucomm.
      when 'COPYROW_OWN'.
        perform copy_row using    me
                         changing gt_bis_cf_out.
Sample code for copying the current line:
FORM COPY_ROW using    po_alv_own          type ref to gcl_alv_own
               changing pt_table_alv      type gt_table_alv_t.
data: l_index         type i,
        ls_table_alv   type gs_table_alvt_t.
call method po_alv_own->get_current_cell
     importing
       e_row     = l_index.
*      e_value   =
*      e_col     =
*      es_row_id =
*      es_col_id =
*      es_row_no =
"read the current line:
read table pt_table_alv index l_index
                           into ls_table_alv_out.
"some changes for the new row:
clear: ls_table_alv-style,
         ls_table_alv-tabix.
"insert the new line:
add 1 to l_index.
insert ls_table_alv into pt_table_alv index l_index.
po_alv_own->refresh( ).
ENDFORM.                    " COPY_ROW
In this manner the events "after_user_command", "before_user_command" are fired, too!
For information: My problem was, that the ALV-function copied the style-information too, so in the new line, some fields are not editable. At least his field must be cleared!

USER_COMMAND in CL_GUI_ALV_GRID

Hi
Can anyone tell me when the USER_COMMAND event in the ALV Grid (OO) gets triggered? I tried creating handlers for both double_click and user_command events. My double_click seems to fire the way i wanted, but at no case the user_command event is getting fired.
I feel i am making a minor mistake somewhere, which i am not able to figure out.
Any help is greatly appreciated.

Get table for cl_gui_alv_grid

Dear all
I have several cl_gui_alv_grid controls and I like to add 1 double-click handler to all those Grids.
Now when doubleclicking, I need to now which table (they have all the same type) is displayed by this grid.
How can I get this information?
thank you
Herbert

I guess, everyone has missed the fact that we can get the access of the Event Sender as the parameter SENDER. So, you can achieve it by doing like this:
* definition
    methods: handle_double_click
             for event double_click of cl_gui_alv_grid
             importing e_row
                       e_column
                       es_row_no
                       sender.
Set event handler for all the objects
    SET HANDLER g_event_receiver->handle_double_click
                                  FOR all instances.
For the method implementation
method handle_double_click.
   case sender.
      when o_Grid1.
*        grid1 processing
       when o_grid2.
   endcase.
endmethod.

Unable to get automatic event handling for OK button.

Hello,
I have created a form using creatobject. This form contains an edit control and Search, Cancel buttons. I have set the Search buttons UID to "1" so it can handle the Enter key hit event. Instead its caption changes to Update when i start typing in the edit control and it does not respond to the Enter key hit. Cancel happens when Esc is hit.
My code looks like this -
Dim oCreationParams As SAPbouiCOM.FormCreationParams
        oCreationParams = SBO_Application.CreateObject(SAPbouiCOM.BoCreatableObjectType.cot_FormCreationParams)
        oCreationParams.UniqueID = "MySearchForm"
        oCreationParams.BorderStyle = SAPbouiCOM.BoFormBorderStyle.fbs_Sizable
                Dim oForm As SAPbouiCOM.Form = SBO_Application.Forms.AddEx(oCreationParams)
oForm.Visible = True
'// set the form properties
        oForm.Title = "Search Form"
        oForm.Left = 300
        oForm.ClientWidth = 500
        oForm.Top = 100
        oForm.ClientHeight = 240
        '// Adding Items to the form
        '// and setting their properties
        '// Adding an Ok button
        '// We get automatic event handling for
        '// the Ok and Cancel Buttons by setting
        '// their UIDs to 1 and 2 respectively
        oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 5
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
        oButton = oItem.Specific
        oButton.Caption = "Search"
        '// Adding a Cancel button
        oItem = oForm.Items.Add("2", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 75
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
        oButton = oItem.Specific
        oButton.Caption = "Cancel"
oItem = oForm.Items.Add("NUM", SAPbouiCOM.BoFormItemTypes.it_EDIT)
        oItem.Left = 105
        oItem.Width = 140
        oItem.Top = 20
        oItem.Height = 16
        Dim oEditText As SAPbouiCOM.EditText = oItem.Specific
What changes do i have to make to get the enter key to work?
Thanks for your help.
Regards,
Sheetal

Hello Felipe,
Thanks for pointing me to the correct direction.
So on refering to the documentation i tried out a few things. But I am still missing something here.
I made the following changes to my code -
oForm.AutoManaged = True
oForm.SupportedModes = 1 ' afm_Ok
oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 5
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
oItem.SetAutoManagedAttribute(SAPbouiCOM.BoAutoManagedAttr.ama_Visible, 1, SAPbouiCOM.BoModeVisualBehavior.mvb_Default)
        oButton = oItem.Specific
        oButton.Caption = "OK"
AND
oForm.Mode = SAPbouiCOM.BoFormMode.fm_OK_MODE
oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 5
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
oItem.AffectsFormMode = False
I get the same behaviour OK button changes to update and enter key does not work.
Could you please tell me find what is it that i am doing wrong?

How can I create events dynamic for a Group/List?

Hey,
atm I'm programming a little application where i want to add elements to my center-pane.
Simpyfied I got:
- Center Pane : here shall the elements appear on right click in bottom-pane. This pane shall be used as anything like a playground where you can drag/drop and connect items from the bottom-pane
- Bottom Pane: here I got about 180 elements which are quite equal. This is sth like a menu of items which you can use. I realised them in java classes extended from a parent class with differend calulations.
What I want:
I want to create an event handler for EACH of the "menu" elements dynamically. Just sth like:
    for (int i = 0; i < basic_menu_list.size(); i++)
      final Element el = hbox_bottom.getChildren().get(i);
      hbox_bottom.getChildren().get(i).setOnMouseClicked(new EventHandler<MouseEvent>()
        public void handle(MouseEvent event)
          if (event.isSecondaryButtonDown())
            playground.add(el);
            redrawPlayground();
    }But as i expected this doesnt work...
Now my question:
How can I solve this problem? Is there any option to listen to all elements of a group without hard-coding every single listener?
Thanks for your help,
Martin

How can I use the same event case for different controls dynamically

OS: Linux 2.6.24-1-686 #1 SMP Sat Apr 19 00:37:55 UTC 2008 i686 GNU/Linux
LabVIEW: Version 8.2
I have a lot of (about 50) controls (numeric, boolean) on my front panel. If a "Value Change" event will be fired by any of them the same event case shall be executed. As I do not want to add all 50 controls to the same event case manually I am looking for a way to do it at run time. Additionally the VI is still under contruction, i.e. controls will be added and removed.
Thanks for any help here.
Regards,
Johannes
Solved!
Go to Solution.

Hi Johannes,
collect all your control references (you can use the FP property for it) and create a user event. Connect this user event to your event structure. Now you have one event case for all your controls. See the attached picture.

How do I create a new event entry for a specific calendar?

In my iMac Calendar app, I have created a few calendars for different functions. But every time I try to create a new event entry for a specific calendar, the app seems to prefer a different calendar instead by default. I cannot enter events in other calendars. Is there a way to do this? In previous versions, I would highlight the particular calendar I wanted to work with and the entry would go into that calendar. Thanks!

You don't. Moments in Photos are the new Events, i.e. groupings of photos sorted by date taken.
When the iPhoto Library was first migrated to Photos there was a folder created in the sidebar titled iPhoto Events and all migrated iPhoto Events (which are now Moments) are represented by an album in that folder. To open the sidebar if it's not already open use the Option+Command+S key combination.
There's a way to simulate events in Photos.
When new photos are imported into the Photos library go to the Last Import smart album, select all the photos and use the File ➙ New Album menu option or use the key combination Command+N. Name it as desired. It will appear just above the iPhoto Events folder where you can drag it into the iPhoto Events folder
When you click on the iPhoto Events folder you'll get a simulated iPhoto Events window.
The downside to the simulation is that the Albums/Events can only be sorted automatically by Title. But they can also be sorted manually, either in the sidebar or in the folder's window at the right.
Ask Apple for more sorting options in Photos via https://www.apple.com/feedback/photos.html.

Hi Scott,
I need a transaction from the MDB since I am not using an EJb to pursue the action.
Hence I need to retain the <trans-attribute>Required</trans-attribute> at the
MDB.
Have any answers?

It's resolved.
The MDB automatically created by JMS Event Generator defaults to be deployed
with
“transacted”. That requires the foreign JMS provider to be “XA”.
The deployment descriptor is created as <domain-directory>/WLIJmsEG_<event_gen_name>.jar
e.g. C:\bea812\user_projects\domains\jmsInterop\WLIJmsEG_mqQueueEventGen.jar
Since MQ in the localhost and remote SLUDV18 are not XA-enabled, we had
to manually
change the <container-transaction> section in ejb-jar.xml:
From :
<trans-attribute>Required</trans-attribute>
To:
<trans-attribute>NotSupported</trans-attribute>

were tested fine with JMS java code using local JNDI names of foreign
JMS objects.
So we know that foreign Queue is active and accessiable from webLogic.
Anyone run into this? Solution?

EmailRecieved Event handler for incoming email in Sharepoint 2013

Hi,
I am developing custom event handler to enable incoming email for custom document library. i have couple of questions.
1. Once i attached the event handler, i could see incoming email settings for the custom document library, but it displays only 2 options as below :
              1. Allow this document library to recieve email
                             Yes       No
                2. E-mail address
All other properties are not displaying. Is this normal behaviour on custom event handler for custom document library or any issue anywhere?
2. So i have given other properties using powershell as below:
$list = $web.lists["invoice Documents"]
$list.EmailAlias ="TestDocument"
$list.EnableAssignToEmail = $true
$list.rootFolder.Properties["vti_emailusesecurity"] = 1
$list.rootFolder.Properties["vti_emailsaveattachments"] = 1
$list.rootFolder.Properties["vti_emailattachmentfolders"] = "root"
$list.rootFolder.Properties["vti_emailoverwrite"] = 0
$list.rootFolder.Properties["vti_emailsavemeetings"] = 0
$list.rootFolder.Properties["vti_emailsaveoriginal"] = 0
$List.RootFolder.Update();
$list.Update();
here i have given vti_emailusesecurity as 1, so it should allow incoming email for the user who has permission for the list.
But any user from the domain is sending mail to this list, the Emailrecieved event handler is triggered. I am expecting that this event handler should not be triggered and expecting access denied error in the ULS Log. But that is not happening, and emailrecived
is triggered and email is delivering to this address successfully.
Can you please anyone help if experience on this?
Thanks
Sathya

Global event handler for preinitialize

Is there anyway to add a global event handler on the
components preinitialize event?
What I need to do is to be able to enable / disable, and show
/ hide component dynamically based on a access list. My plan was to
have a global event handler that listens to the preinitialize
event, at that time, checks if the user has access to the component
or not. If not, I'll disable / hide the component.
What I did so far is:
in my main app.mxml file, I have:
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
preinitialize="preinit(event)"
so the preinit() function is invoked on the app's
preinitialize event.
Then I have the preinit() function (see attached code below).
However, it does work as there is no trace message printed.
I changed to use KeyBoardEvent.KEY_DOWN and that seems
working when I press any key.
I also tried to use the app.stage.addEventListener() but the
stage object is null in the preinitialize event.
Thanks in advance for your help.

Thank you for follow up on my question.
I do know these two properties. But that does not solve the
problem. Let me explain it with an example.
That's say, when the user logs in, I loads the access list.
Then the app displays a panel with some form entries. If I am able
to register a global event listener for the component
initialization events, I can check the permission and optionally
hide some components. Otherwise, I would need to programmatically
travels my component tree to evaluate each component individually
to set there visible/includeInLayout properties, which is error
prone.
The problem is that the component is visible to one user but
would be hidden to another, so it can not be set at the design
time.
The approach I am using right now is to extend the default
components to add an event listener. But I'd like to know if it is
possible to register a global event listener to be notified when
any component is created. As my first post says, I tried to use the
systemManager and listen to the PREINITIALIZE event, but that
didn't get always get invoked.

Event handler for selecting 3d views

Hi,
Is there any event handlers for when a user selects a view?
I would like to be able to base actions after a view is selected but can't figure away to do it other then creating my own list of views.
Thanks!

...Yes indeed! :-) It's called the CameraEventHandler. It gets triggered whenever a user changes a view. You can use the returned "event" object to get info about the camera (or modify it), to just use the eventHandler to trigger other activity as you mentioned.
Here's a simple example which outputs all the camera properties to the console window at view change.
//===============================================
myCEH = new CameraEventHandler();
myCEH.onEvent = function(CameraEvent)
console.println("CameraEvent.binding = " + CameraEvent.binding );
console.println("CameraEvent.far = " + CameraEvent.far );
console.println("CameraEvent.fov = " + CameraEvent.fov );
console.println("CameraEvent.currentTool = " + CameraEvent.currentTool );
console.println("CameraEvent.canvas = " + CameraEvent.canvas );
console.println("CameraEvent.isNewCanvas = " + CameraEvent.isNewCanvas );
console.println("CameraEvent.near = " + CameraEvent.near );
console.println("CameraEvent.projectionType = " + CameraEvent.projectionType);
console.println("CameraEvent.targetDistance = " + CameraEvent.targetDistance);
console.println("CameraEvent.transform = " + CameraEvent.transform );
console.println("CameraEvent.viewPlaneSize = " + CameraEvent.viewPlaneSize );
runtime.addEventHandler(myCEH);
//===============================================

Event Receiver for all Page Libraries in a Site Collection

We have a single site collection with many different page libraries. I'd like to create a single event receiver for ALL page libraries in the site collection (850- Page Library). Can you do this?
The event receiver will essentially remove/expire something we have stored in the System.Web.HttpRuntime.Cache. We are caching the content in the Page Library and would only like to expire the cache when a new page or change is performed on some
content in the page library.

Hi,
We can create a new feature and add an event receiver to the feature for all Page Libraries.
For more information, you can see the link below:

How to add event handling for a menu?

hi,
I have created a menu and few mneu items.
for eachmenu itme , i did event handling and it is workign fine.
it was like this
menuItem = new JMenuItem("Exit",KeyEvent.VK_X);
menuItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_X, ActionEvent.ALT_MASK));
menuItem.addActionListener(this);
menu.add(menuItem);
     public void actionPerformed(ActionEvent e)
JMenuItem source = (JMenuItem)(e.getSource());
String s = "Action event detected. Event source: " + source.getText();
System.out.println(s);
public void itemStateChanged(ItemEvent e)
JMenuItem source = (JMenuItem)(e.getSource());
String s = "Item event detected. Event source: " + source.getText();
System.out.println(s);
now int he second menu i don't have any menu item and i want to do the event handling for the menu itself. any ideas how to do it. following is the code for the menu
//Build the second menu.
menu2 = new JMenu("Options");
menu2.setMnemonic(KeyEvent.VK_O);
menuBar.add(menu2);
menu2.addActionListener(this);     //this does nto work

You were on the right track. However, selecting a menu is different from selecting a menu item. MenuItem chucks an ActionEvent and Menu will send an ItemEvent.
If you pile all action output to one actionPerformed method then be careful of your assumptions on what the source type will be. If by any chance the Menu has sent an ActinoEvent then your code will have caused a ClassCastException.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MenuTest implements ActionListener, ItemListener {
    JMenuItem menuItem;
    JMenu menu1, menu2;
    JMenuBar menubar;
    JFrame frame;
    public MenuTest() {
        frame = new JFrame("MenuTest");
        frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE);
        menubar = new JMenuBar();
        frame.setJMenuBar(menubar);
        menu1 = new JMenu("File");
        menu1.setMnemonic(KeyEvent.VK_F);
        menuItem = new JMenuItem("Exit",KeyEvent.VK_X);
        menuItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_X, ActionEvent.ALT_MASK));
        menuItem.addActionListener(this);
        menu1.addItemListener(this);
        menu1.add(menuItem);
        menubar.add(menu1);
        //Build the second menu.
        menu2 = new JMenu("Options");
        menu2.setMnemonic(KeyEvent.VK_O);
        menu2.addActionListener(this); //this does not work
        menu2.addItemListener(this); // use this instead
        menubar.add(menu2);
        JPanel panel = new JPanel();
        panel.setPreferredSize(new Dimension(100,100));
        frame.getContentPane().add(panel);
        frame.pack();
        frame.show();
    public void actionPerformed(ActionEvent e)
        String s = "Action event detected. Event source: " + e.getSource();
        System.out.println(s);
    public void itemStateChanged(ItemEvent e)
        String s = "Item event detected. Event source: " + e.getSource();
        System.out.println(s);
    public static void main(String[] args) {
        new MenuTest();
}

Event handler for STDIN input?

Hi,
This question will probably require a bit of context - I'm attempting to re-implement in java an application that's currently written in perl. The application is a server helper app that rewriters urls; it receives a request ID and a URL on stdin, does the necessary munging (which can require an external SOAP query), then returns the resulting rewritten URL.
Since the results can be asynchronous due to the need for external queries to build the result, this is currently a multithreaded perl app implemented using perl's POE framework to register an event handler for stdin. That handler fires each time a line of input is received, then feeds the query to a thread pool manager (POE::Component::Pool::Thread, which is conceptually similar to the Executor frameworks). The thread returns the result as a callback registered to another function in the main thread, which then populates the query/result to a cache then outputs the result (with the original query ID) on stdout. Since stdin input and the result callbacks are event-driven, there's no while(true) main loop or other blocking mechanism in the main thread. Unfortunately, it's perl-ness is causing problems due to perl's threading implementation (three words: "copy on init"), so we need to reimplement in a language with a more robust threading implementation (preferably one with copy-on-write for shared objects). So, Java it is.
So far everything's been good - Executor, Callables, and Futures work as I hoped they would for proper thread management, and the internal worker thread logic (XML processing, SOAP, regular expressions, etc) is proving rather simple to adapt. However, the main roadblock I'm hitting is that so far, I have not found a way to register any sort of event handler for STDIN input (or more specifically, InputStreamReader/BufferedStreamReader events). This could be due to search engine pollution - everything I see when I search for documentation on event listeners appears to be GUI-specific (buttons, menus, text areas/forms, etc). I'm just looking for a way to handle a line of STDIN, not a text area on a form.
Any pointers in the right direction will be much appreciated!

Maybe I need to rethink the design here...
The main reason I used a callback in the original perl is that there's a large cache structure that gets checked before the thread dispatch, and only cache misses get pushed to a thread for processing. Callbacks from the threads will then add its results to the cache. Thanks to perl's thread model, when I attempted to make the cache a shared structure - in perl, you have to explicitly mark as "shared" variables that you want visible to all threads - the structure wound up getting copied to every thread, and this gave the app an unacceptable memory footprint. So the solution was to use a callback in the main thread to update the cache.
I'm now thinking that if Java's thread model is a bit saner (i.e. a shared object doesn't get copied into every thread), then I could just have each thread update the cache, print its output to STDOUT directly, and avoid the need for the callback. I can then make my input loop simply a while() loop, waiting for the next input to dispatch. Sound sane?Yes I think so.
There is some of this I still don't entirely understand. Your loop sounds better now but it sounds to me like the process is this.
1) read from in
2) call some stuff on the basis of what came in
3) do work
4) workers produce things
5) things written back out
6) read back in??
If you're just going in/out then great. If you are going in/out/in then maybe some sort of PipedInput/Output Streams? It may well be that I got lost in your explanation in which case never mind.
