Event top_of_page im OO-ALV

[Anakin3132]

Hallo,
hat jemand schon mal den event top_of_page im OO-ALV ausprobiert?
Ich kriege den Event trotz Set Handler ... nicht geraist.
Der Aufruf über Create Object der Klasse CL_DD_DOCUMENT und Methoden ADD_TEXT bzw. DISPLAY_DOCUMENT funktioniert, aber nicht der SET HANDLER.

Hallo Michael,
beim OO-Alv kann man eine Überschriftszeile über dem Grid anzeigen lassen durch Übergabe einer Layout-Struktur (TYPE lvc_s_layo). In dieser Struktur gibt es das Feld GRID_TITLE, in das man die Überschrift eintragen kann.

DATA: gs_layout TYPE lvc_s_layo. " Layoutstruktur für ALV
...
gs_layout-grid_title = 'Überschift'.
...
CALL METHOD my_alv_grid->set_table_for_first_display
EXPORTING
is_layout = gs_layout
...
Gruß

Hallo Wolfgang,
das ist mir bekannt, aber da kann ich nur eine Überschriftszeile eingeben. Ich will aber mehrere Zeilen darstellen können - so wie beim i_callback_html_top_of_page des FuBa REUSE_ALV....

Hallo Michael,

Hallo Wolfgang,
danke für den interessanten Link. Nur diese Funktionalität habe ich auch schon über die Klasse CL_DD_DOCUMENT.
Ich wollte eigentlich den EVENT top_of_page ausprobieren. Aber dies funktioniert auch nicht im SAP-Testprogramm BCALV_TEST_GRID_EVENTS.

Moin,
diese Events werden im Zusammenhang mit Drucken benutzt

About Printing
There are some events that you can utilize about printing.
You simply write what is to be output in methods handling these events.

Here is the list of events in this context.
print_end_of_list Define output text to be printed at the end of the entire list
print_top_of_list Define output text to be printed at the beginning of the entire list
print_end_of_page Define output text to be printed at the end of each page
print_top_of_page Define output text to be printed at the beginning of each page

das top_of_page event wird verwendet um z. B ein "Dokument" in den oberen Teil eines Splitter Containers zu bringen.

Beispiel:

Code: [Select all] [Expand/Collapse] [Download] (Untitled.txt)
