* § 2.In event handler method for event TOOLBAR: Append own functions
* by using event parameter E_OBJECT.
DATA: ls_toolbar TYPE stb_button.
*....................................................................
* E_OBJECT of event TOOLBAR is of type REF TO CL_ALV_EVENT_TOOLBAR_SET.
* This class has got one attribute, namly MT_TOOLBAR, which
* is a table of type TTB_BUTTON. One line of this table is
* defined by the Structure STB_BUTTON (see data deklaration above).
*
* A remark to the flag E_INTERACTIVE:
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 'e_interactive' is set, if this event is raised due to
* the call of 'set_toolbar_interactive' by the user.
* You can distinguish this way if the event was raised
* by yourself or by ALV
* (e.g. in method 'refresh_table_display').
* An application of this feature is still unknown... :-)
* append a separator to normal toolbar
