You should understand about Object Events before reading this posting.
There are a lot of events fired in the object oriented ALV based on class CL_GUI_ALV_GRID. You can receive them and use for your actions.
This template program can be helpful to follow the calls of events. It registers handler for all of them. The handler calls a method when the event is triggered.
This program also registers handlers for protected, inherited events of class CL_GUI_ALV_GRID_BASE. To do this, the class of event receiver have to be child of the class CL_GUI_ALV_GRID_BASE. Some of this events seems to be very promising, for example TOOLBAR_BUTTON_CLICK.
If you want to start the program in your system, besides copying the source code, you have to create screen, GUI status, etc. See the comment at the beginning of the program for the detailed instruction.
PROGRAM zkmalvev.
* 1. SE38: create executable program (type 1), use PROGRAM
* instead of REPORT because it will have screen and modules
*
* 2. SE80: create screen 0100
*
* 3. Screen Painter: on the screen 0100 create 'Custom control'
* CONT1_0100
*
* 4. SE80: for screen 0100 set the variable OK_CODE for the element OK
*
* 5. SE80: create calls to PBO and PAI in the flow logic of screen 0100:
*
* PROCESS BEFORE OUTPUT.
* MODULE pbo_0100.
* PROCESS AFTER INPUT.
* MODULE pai_0100.
*
* 6. SE80: create GUI Status STAT_0100, assign functions EXIT and SAVE
* to standard icons, eventually create your own toolbar button
