ALV Tree - register event problem

Hi,
I'm trying to register standard events for ALV Tree. when perform register_events it raises exception 'illegal event combination'. does anybody know what is wrong it this code ?

I've finally fixed the problem:
there was:

and should be:

ALV Tree and set_table_for_first_display problem

I am trying to create an alv tree. I have some sample code that uses the sflight table and this works fine however when i replace sflight with my internal structure and table it crashes at set_table_for_first_display with a "Field symbol has not been assigned" error.
This is part of the original code that works. *This isn't all the code just the relevant parts.

When it runs like this it crashes at set_table_for_first_display

The code I am using as an example is BCALV_TREE_SIMPLE_DEMO. If I have no data in my table it doesn't error when I call set_table_for_first_display.
But it looks like I might have to use that one instead because from what I understand you can use cl_gui_alv_tree_simple when the input table has all the required columns such as sflight but you use cl_gui_alv_tree when you need an internal table.

Displaying ALV tree in expanded form in first ouput

Hi all,
 I have a problem with alv tree. My requirement is, on the first output itself the alv tree should appear expanded depending on one of the filter criteria in the tool bar. How can i trigger the toolbar event in PBO itself? Can it be done? if yes please provide sample code. Points assured for helpfull answers.
Thanks,

Hello Mohit
Here is a sample routine (taken from BCALV_TREE_02) which you have to add and adapt for your report. It does two things:
1. Register events that should be handled (required but not sufficient for event handling)
2. Set event handler for registered events
The first step is different from ALV grid controls because here all events are already registered with the control (not the control framework).
Set the event handler (statement SET HANDLER) registers the event handling with the control framework.

ALV Tree event registration doesn't work

Hello Experts,
the following is the registration-form which shall register a item-double-click event to my alv-tree-object. when doing the double-click it doesn't open my own methods in the event-handler class but the standard ones and nothing happens further.
Any ideas?
Many thanks in advance!

It doesn't matter where I place my double-click. The standard event handling "handle_event" is called.
Instead of this I would like to have my coding.....
Changing the cl_gui_alv_tree to cl_gui_column_tree doesn't work since my tree isn't a reference of column_tree but of alv_tree. So I would have to rebuild nearly the entire tree. This cannot be a solution since I guess the double-click item should work anyway.

Interactive ALV tree problem

Hi all,
Please help,
I have created ALV tree, with the help of standard program bcalv_tree_01. now i want to create it interative like DOUBLE CLICK on any ITEM or NODE. so i have define class and implement it with two method for event NODE_DOUBLE_CLICK and ITEM_DOUBLE_CLICK. and i have register it. when i display the tree it doesn't expand, but i comments the CALL METHOD gd_tree->set_registered_events it works fine. should i have to implement the event EXPAND_NO_CHILDREN also?
and what should be the code, becoz i am new in alv tree and oops. for sytex please refer BCALV_TREE_01.
please help as soon as possible.
Thanks in advance.

Hi!
Ya you have to code for the method EXPAND_NO_CHILDREN
Where you will be defining the childs to the particular node.
the better example for it you can refer to SAPSIMPLE_TREE_CONTROL_DEMO
where
HANDLE_EXPAND_NO_CHILDREN method implemented shows the childs added and METHOD HANDLE_NODE_DOUBLE_CLICK
implemented to handle the doulbe click.
Regards.

ALV Tree Problem

Hi ;
i am trying to expand the tree according to tree level.
loop at itab where level = lvl.
 clear snode.

when lvl = 1 everything is ok it expands level 1 nodes
but if lvl greater than 1 (2,3,4 ...) it gives error

Problem in ALV Tree

Hello Friends,
I am using ALV Tree to display a report.
In this report for a particular input.2 nodes are cerated.
On clicking on the 2nd node the details for the same are shown .
However on clicking the 1st node , the system automatically logs off closing all the SAP sessions and even the SAP Logon pad.
Suppose i am on executing the program on development server,even the sessions of test server are closed.
Can anyone please help me in this.....
its a bit urgent.
i am attaching my code for reference.

Problem with register event callback in use of instrument control

now, i use the register event callback to register a value change of a boolean control on the front panel, and wire the cluster's ref of the instrument control parameters to the user parameter input, then create the callback vi. In the callback vi, i select the pump-control subvi, and pass the user parameter to the subvi. The problem is that, when i press the boolean control, the instrument (here is pump) can act, but immediately, the code crashes.
I use labview 8.6
Attachments:
callback vi.png ‏8 KB
register event callback.png ‏8 KB

You would wire the event registration wire that comes out of the Register for Events node into an event structure. You will need to right click on the event structure and check off "Show Dynamic Event Terminals" and it into that. Then you can create a new Event Case that uses the dynamic event. You can place your subVI in that event in whatever way you want. (Just drop the subVI in or do a Call by Reference there, or whatever.) Look in the Example Finder for "Dynamically Register for Events.vi".

ALV Tree Problem with Checkboxes

Hello,
i've got a problem.
I have an ALV-Tree and die ALV-Detaillist of the tree are type checkbox.
That's working correct.
But i want to fill initial data in the checkboxes but the checkbox isnt set.
i've done as followed:
CALL METHOD go_alv_tree->set_table_for_first_display
 EXPORTING
 I_STRUCTURE_NAME =

 I_LOGO =
 I_BACKGROUND_ID =
 IT_TOOLBAR_EXCLUDING =
 CHANGING
 it_outtab = <go_data_tab>
 IT_FILTER =
 it_fieldcatalog = lt_fcat.
fieldcat are several fields all as checkbox.
Then i get a component of the output structure and set a X.
ASSIGN COMPONENT lv_help_arbpl OF STRUCTURE <go_data_struc>
 TO <fs_arbl>.
 IF <fs_arbl> IS ASSIGNED.
 <fs_arbl> = lc_xfeld.
 ENDIF.

 i_node_text = lv_node_text
 IMPORTING
 e_new_node_key = lv_period
 EXCEPTIONS
 relat_node_not_found = 1
 node_not_found = 2
 OTHERS = 3.
in <go_data_struc> the fields which should be set, are set with X.
But after i add all of my nodes and do CALL METHOD p_go_alv_tree->frontend_update, the checkbox is empty but there is an X in the field beside the checkbox.
Thanks in advance.
best regards,
Dennis

Ok i solved the problem.
best regards,
Dennis

ALV Tree - Event Handler

Hi All,
I amd currently developing an ALV tree program to capture the hierarchy of functional location. I managed to display the hierarchy in ALV Tree using cl_gui_column_tree.
Now, i am working on double clicking the functional location and it will bring me to tcode IL03. But, it seems like i cannot capture of the field value clicked. Below are my source code. Can anyone pls help me on this? Thank you very much

Hello Goh
Based on your coding you are using CL_GUI_ALV_TREE instead of CL_GUI_COLUMN_TREE.
Calling method get_selected_item within your event handler method is unnecessary because these data are already provided by the event interface.

lt_fieldname TYPE lvc_fname.

ALV Grid Event Problem

Hi,
I have a dialog that contains an ALV grid and three buttons. When the ALV grid is created, it's parent is specified as a custom container.
Container
data : g_custom_container type ref to cl_gui_custom_container.
ALV Grid
data : g_grid             type ref to cl_gui_alv_grid.
    create object g_custom_container
           exporting container_name = p_cont_name.
    create object g_grid
           exporting i_parent = g_custom_container
           I_APPL_EVENTS = 'X'.
I would like the user to be able to just hit enter to accept the values displayed in the ALV. My problem is that when the dialog is created, the ALV has focus so the event isn't getting to the PAI of the dialog. If I click the mouse outside of the ALV to take focus away from the ALV, hitting the enter key does trigger the correct event in the dialog PAI. How can I either set the focus outside of the ALV when the dialog loads, or make the ALV forward the event to the dialog.
Thank you very much for any isight you can lend!

Hi John, are you working with an editable ALV grid? If so, the code below will allow an event to be fired when the user hits enter after the data has been changed.
           call method alv_grid->register_edit_event
                        exporting
                           i_event_id = cl_gui_alv_grid=>mc_evt_enter.
You then need to create an event handler to handle the event being fired when the data is changed.
*   create Event Receiver
          create object event_receiver.
*   handler for ALV grid
          set handler event_receiver->handle_data_changed for alv_grid.
