Capturing Scroll Event

abhishek_katti — Mon, 01 Sep 2008 11:33:50 GMT

Hi Expert,

I have a vertical scroller in my table control and I have also declared the Functions as PageUP, PageDown, FirstPage & Last Page in PF-status.

When I use to scroll through mouse or with Page up/Page down keys, my module pool program doesnt capture any event(OK_CODE) as functions I have declared. The OK_CODE is blank for such functions/events.

Please help me what I'm missing

Thanks.

check this code

MODULE scroll INPUT.

XCODE = OK_CODE.
CASE xcode.

WHEN 'PGDO'. "one page down
offset = tabcontrl-lines - step_lines.
IF tabcontrl-top_line LT offset.
tabcontrl-top_line = tabcontrl-top_line + step_lines.
ENDIF.

WHEN 'PGUP'. "one page up
offset = step_lines.
IF tabcontrl-top_line GT offset.
tabcontrl-top_line = tabcontrl-top_line - step_lines.
ELSE.
tabcontrl-top_line = 1.
ENDIF.

WHEN 'PGLA'. " last page
tabcontrl-top_line = tabcontrl-lines - step_lines + 1.

WHEN 'PGFI'. " first page
tabcontrl-top_line = 1.

ENDCASE.

ENDMODULE. " SCROLL INPUT
