Message handling in ALV events

I have a screen with ALV Grid control. This grid has columns (attributes of more than one material). Now when I select more than one column and click on a button added on the ALV grid toolbarit triggers a button click event and in the implementation I have written a code to check whether the selected columns (ie attributes) are from same material or not.if not from same material it throws an error message (Message type E). Once the error message is displayed doing any operation exits from the program.as the Message type E exits from the program.
The requirement is to remain on the same screen and not exit. Error will disappear only on selecting columns from the same material and press the button.
Note : There are no input fields here. So the concept of Chain-EndChain doesnt hold good.

i am working in CL_GUI_COLUMN_TREE class.Also using Check box. Now i want to handle events for check box . I am new to ABAP Objects.
Pls expaline in detail or send code
thanks in advance,
senthil kumar.r

Hello Senthil
Have a look at the sample report
SAPCOLUMN_TREE_CONTROL_DEMO
. The crucial points are:
(1) Register the required events at the control
* define the events which will be passed to the backend
" checkbox change
event-eventid = CL_GUI_COLUMN_TREE=>EVENTID_checkbox_change.
event-appl_event = 'X'.
append event to events.
CALL METHOD G_TREE->SET_REGISTERED_EVENTS
 EXPORTING
 EVENTS = EVENTS
 EXCEPTIONS
 CNTL_ERROR = 1
 CNTL_SYSTEM_ERROR = 2
 ILLEGAL_EVENT_COMBINATION = 3.
IF SY-SUBRC <> 0.
 MESSAGE A000.
ENDIF.
(2) Set the event handler
assign event handlers in the application class to each desired event
SET HANDLER G_APPLICATION->HANDLE_CHECKBOX_CHANGE FOR g_tree.
(3) Define and implement event handler method
METHOD HANDLE_CHECKBOX_CHANGE.
 " this method handles the checkbox_change event of the tree
 " control instance
 " show the key of the node and the name of the item
 " of the clicked checkbox in a dynpro field
 G_EVENT = 'CHECKBOX_CHANGE'.
 G_NODE_KEY = NODE_KEY.
 G_ITEM_NAME = ITEM_NAME.
 CLEAR G_HEADER_NAME.

Handle single click event in ALV OOPS

Hi,
I have to display 2 ALV grid...one above the other.
Top ALV will contain Header info and bottom ALV witll display line item.
I am use ALV OOPS.
Now when user will click on the top ALV ...bottom ALV should show corresponding data.
I don't have to use HOTSPOT or Double click event.
How can I handle single click event.
Please guide me..thanks in advance
Regards,
Prasoon

hi,
 for this in ALV OOPS take 2 custom containers( cl_gui_custom_container)in the same screen and on the 1st container display the header data(use set_tale_for_first_display method of class cl_gui_alv_grid).
 On the 2nd screen item data for this use EVENT handling(you want single click). use hotspot_click or button_click events.
for this you have to register the events. the code for that.
CLASS lcl_event_handler DEFINITION .
PUBLIC SECTION .
METHODS:
*--Hotspot click control
handle_hotspot_click
FOR EVENT hotspot_click OF cl_gui_alv_grid
IMPORTING e_row_id e_column_id es_row_no ,

*--Registering handler methods to handle ALV Grid events
SET HANDLER gr_event_handler->handle_hotspot_click FOR gr_alvgrid .
SET HANDLER gr_event_handler->handle_button_click FOR gr_alvgrid .
do n't forget to use refresh_table_display
 other wise only the record which you first you clicked will display in the 2nd container.

ABAP WebDynpro: Handling the ON_ENTER Event in editable ALVs

Sub: ABAP WebDynpro : Handling the ON_ENTER Event in editable ALVs
Hi,
I would like to know if there exists an event to handle TABout (i.e, when user navigates out of the cell with a TAB key-press) for a cell of an editable ALV.
Alternatively, any help on how to handle ON_ENTER event and how it is triggered when data is entered by user into a cell of an editable ALV, would be really appreciated.
Thanks,
Adithya

Hi
I had one similar problem where user enter something into the editable cell and press enter. to handle this scenario i used WDDOBEFOREACTION method of my view to call alv interface method check_data.
if there is any change in the any table cell, it will fire an event on_data_check..which has paramater column name, row index and new and old value of the cell.
you can handle this event and write your business logic in event handler method.
hope it will help

No handler for system event CustomHourlyEvent has been registered

I have written a scheduled event to trigger on daily basis using CustomDaily event mentioned in the ScheduledEvent component. I have referred HowToComponents in order to write this filter. But I am getting following error in my logs and my scheduled event is not getting executed.

<tr><td>Error</td><td>8/23/12 12:01 PM</td><td>No handler for system event CustomHourlyEvent has been registered. stack trace [ <a href="javascript:if(typeof show!='undefined')show('0.31115227955456604')">Details</a> ]

Please let me know if anybody has countered the same problem while writing ScheduledEvent filter.

I was able to solve this issue by updating the state of the event. HowToComponents - ScheduledEvent has the following method:
* Update the state of the event. Must be done at least once to tell the content server
* when the scehduled event is finished.
protected void update(String action, String msg, Workspace workspace) throws ServiceException, DataException
 long curTime = System.currentTimeMillis();
 ScheduledSystemEvents sse = IdcSystemLoader.getOrCreateScheduledSystemEvents(workspace);
 sse.updateEventState(action, msg, curTime);
Making a call to update() when my scheduled event ran solved the issue for me.

How to handle double click event in a text control

Hi,
 Will u please send me information on handling double click events inside text control and also about locking and unlocking of DB tables for updation.
Regards,
Praba.

Hi Prabhavathi,
Here is how you handle double click events in Textedit control.
1)Create a custom control in screen (say TEXT_CONTROL)
2)In main program,
a) Declarations:
data: obj type ref to cl_gui_custiom_control.
 text type ref to cl_gui_textedit.
b) Create the instance of custom container
c) Create the instance of textedit control.
3)Now to handle double click events , create a local class as follows.
class shail_event definition.
public section.
methods:
handle_doubleclick for event dblclick of cl_gui_textedit .
endclass.
class shail_event implementation.
method handle_doubleclick .
here do the coding for handling the double click.
endmethod.
endclass.
4) Create an instance of the handler class(ie.ZSHAIL_EVENT).Let it be named hand.
5) Define varibles for event.
DATA: i_events TYPE cntl_simple_events,
 wa_events TYPE cntl_simple_event.
SET HANDLER hand->handle_doubleclick for text.
wa_events-eventid = cl_gui_textedit=>event_double_click.
wa_events-appl_event = 'X'. "This is an application event
APPEND wa_events TO i_events.
6)
 CALL METHOD texte->set_registered_events

ALV Event is malfunctioning

Hello gurus,
I created a workbench with an edittable ALV for its data. This ALV has several tabs, lets say 5 tabs with individual event handler declaration. Tabs 1, 2 & 3 shares the same event/class and method declaration. 4&5 shares also the same but different to 1,2, & 3.
I have events handle data change and button click (for a column of buttons that pops up a screen when pressed), which are both standard toolbar. Then I also have event toolbar for my custom icon and event user command to handle these icons.
I run my ALV, tabs 1,2 & 3 have their data first. Then I just copy these data going to tab4.
On tab 4, whenever I click on the standard toolbar 'add row' (+ icon), it adds new row and triggers event handle data change.
Now my problem is, whenever I click on any other icon that triggers alv event, instead of going to their respective event, it always go to the handle data change event. (i.e. when I click on my custom toolbar icon, instead of going to event user command, it triggers the handle data change. Same with when I click on any buttons under the button columns, it triggers handle data change.)
Tab 1,2 & 3 works fine. But 4 & 5 are not. They have the same process and coded with the same logic. The only difference I see is that 4 & 5 has handle data change event while 1,2 & 3 have not.
Please help me analysing what's really causing the issue and what solution to apply to handle this.
Thanks,
Sheera

you need to set the subtotal option only to the dummy field. see the below code related.
"no need of subtot option here..
ls_sort-spos = 1.
ls_sort-fieldname = 'EBELN'.
ls_sort-tabname = 'ITAB'.
ls_sort-up = 'X'.
ls_sort-group = 'UL'.
APPEND ls_sort TO it_sort.
CLEAR ls_sort.
ls_sort-spos = 2.
ls_sort-fieldname = 'D'.
ls_sort-tabname = 'ITAB'.
ls_sort-up = 'X'.
ls_sort-group = 'UL'.
ls_sort-subtot = 'X'. "Only specify here
APPEND ls_sort TO it_sort.

HOWTO: Handle a click event on a DAC TreeControl

HOWTO: Handle a click event on a DAC TreeControl
Goal: Handle the event that occurs when a user clicks on a new node of a DAC TreeControl. In this example the handler is simple - it just prints out the current node. You can try this example on the DACTree.jpr project in the 3.2 tutorial, described in the online help under
Tutorials and Sample Applications
-> Tutorials
-> Building Enterprise Applications with Business Components for Java
-> Enhancing the Online Orders Application
-> Creating a DAC Client
The problem: The usual procedure for adding an event to a DAC component does not work: if you select your TreeControl in the designer, then select the Events tab of the property inspector, none of the events listed does what we want.
Solution: Get the underlying JTree and add your listener to it. Although the TreeControl is not a subclass of javax.swing.JTree, it does have an underlying JTree which you can get by calling TreeControl.getTree().
Add the following code to your frame's .java file (Hint: Add any event, from the Events tab of the property inspector, then use the generated code as your template, changing it to match this example):
1. Declare a JTree:
JTree tree = new JTree();2. In jbInit(), add the event listener after the code that sets up your TreeControl:
tree = treeControl1.getTree();
tree.addTreeSelectionListener(new javax.swing.event.TreeSelectionListener() {
public void valueChanged(javax.swing.event.TreeSelectionEvent e) {
tree_valueChanged(e);
});3. Add the event handler method:
void tree_valueChanged(javax.swing.event.TreeSelectionEvent e) {
System.out.println("Current node: " + tree.getLastSelectedPathComponent());
}

could you add a mouselistener to the pane or whatever container the pie chart is drawn on? Then override the mouseClicked method to do whatever you want?

I need tips about queued message handler

Hello, I have to use, for the first time a queued message handler. I'd like to know what is the best way to share data between cases in a loop and from a loop to another, I think with local variables isn't the best way...
However all the tips on the queued message handler are welcome!!!
Thanks

Shift registers. Doesn't matter if QMH, State Machine, Producer-Consumer, etc.

Well, now that completely depends on what you are passing around. Streaming data? Use a Queue or User Event. Last known value (ie Tag)? Global Variables, Action Engine.

How best to decouple the UI in the LV 2012 Queued Message Handler Template?

If you create a new "Queued Message Handler" from the new LV 2012 Template, you'll see a blue box in the "Update Display" case which says the following:
Code Recommended - If you wish to decouple the Message Handling Loop from your user interface, consider creating User Events (like the "Stop" event in this VI) to message the Event Handling Loop whenever the user interface needs updating.
I'd like to give this suggestion a shot but I'm struggling to find the best way to do this and still keep the code modular. The template creates a "User Event - Stop.lvlib" with Create/Destroy/Fire SubVI's. I would like to create a similar "User Event - Update UI.lvlib" library with similar Create/Destroy/Fire SubVI's to keep this new user event separate and modular. The problem I'm hitting is that there can only be one Dynamic Event Terminal in the Event Structure so how do I modularlize creating user events into separate SubVIs and still maintain this one Dynamic Event Terminal?
As a follow on question, would it be best to have one user event library per indicator that needs updating or just one single UI update user event and then pass a cluster as the message which contains the name of the control to update (to be used with a case structure) and then the data to go along with it?
Thanks!
Solved!

Instead of having the Register Events in the "Create Methods" you could do that part outside your "create" SubVIs and then simply bundle them. Then you create your individual User Event handling. See snippet where i created a "Create User Event - Update" vi in front of the Stop.

How to handle tab leave event

Hi.
I'd like to handle tab leave event before user selected tab shown.
because I'm making Settings dialog.
So I want to validate tab contents when user leaving the tab.
And stay the tab if invalid user input.
Thanks.

With apologies for the slow reply, I'm currently travelling.
Two things to note:
1) The af:document uncommittedDataWarning flag was designed to stop users navigating away from half entered records. More about this flag can be found here:
http://docs.oracle.com/cd/E23943_01/web.1111/b31973/af_orgpage.htm#CACDDDFH (see point 4)
http://www.oracle.com/technetwork/developer-tools/adf/unsaveddatawarning-096556.html
....please note our documentation from time to time spells this flag wrong with only one "t" in the word committed, so if you're attempting a bulk search check for this (and I'll raise document bugs to get this fixed in the future).
2) On addressing the ADF UI Shell, if you're switching between "pages" in the UI Shell, as separate to switching between dynamic tabs within a single page using the UI Shell, the UI Shell will actually restart the currently running task flow in the page you're returning too. You can verify this by implementing an initializer on your task flow with a log message, and watching when the initializer is called.
In addressing your last question, at this stage I think you need to assess my first answer then come back if you think you sill need to execute the code on the tab click. I also need to know are you talking about the primary level of tabs that represent each page in the UI Shell, or are you referring to the dynamic tabs within a single UI Shell page that hold your task flows?

How to handle form close event or escape key press event for user defined f

Experts,
Please let me know how to handle form close event or escape key press event for user defined form...
Thanks & Regards,
Pravin.

Hi
You can catch the form close event like this
If ((pVal.FormType = 139 And (pVal.EventType = SAPbouiCOM.BoEventTypes.et_FORM_CLOSE)) And (pVal.Before_Action = True)) Then
      Try
               SBO_Application.SetStatusBarMessage(pVal.EventType.ToString())
      Catch ex As Exception
                SBO_Application.SetStatusBarMessage(ex.Message)
        End Try
      End If
Hope this helps

OO ALV Event

hi , all
How can i get the handle for "Enter" event?
Thank you!

Well, do you mean to trigger some checking values in an Editable ALV? If so, you need to tell the ALV specifically that ENTER is an event which triggers the checking of changed data.
You can do this code after the SET_TABLE_FOR_FIRST_DISPLAY.
* Register "ENTER" as an edit event
    call method alv_grid->register_edit_event
                      exporting
                         i_event_id = cl_gui_alv_grid=>mc_evt_enter.
*   handler for ALV grid
    set handler lcl_event_receiver=>on_data_changed for all instances.

RIch Heilman
