ALV drop-down box
As shown in the drop-down box made ALV drop-down box to select 1 to 5, with the view of how the embodiments below
1. Add to a field GT_DATA using the drop-down box:
| TYPES:BEGIN OF ty_data,
checkbox TYPE c,
matnr TYPE mara-matnr,
mtart TYPE mara-mtart,
matkl TYPE mara-matkl,
maktx TYPE makt-maktx,
context TYPE char10,"用于下拉框
END OF ty_data.
DATA gt_data TYPE TABLE OF ty_data WITH EMPTY KEY. |
2. Set fieldcat property:
Set field to enter context provided fieldcat-drdn_hndl = '1'.
(The following is a drop down box corresponding to the group, may be 23,456 to mark ????? group drop-down box, in order to achieve a plurality of drop-down box)
| FORM frm_set_fieldcat.
DATA lv_pos TYPE i.
DATA ls_fieldcat LIKE LINE OF gt_fieldcat.
DEFINE %%append_fieldcat.
lv_pos = lv_pos + 1.
ls_fieldcat-col_pos = lv_pos.
ls_fieldcat-fieldname = &1."字段名
ls_fieldcat-coltext = &2."文本
* ls_fieldcat-no_zero = &3."去掉前导零
ls_fieldcat-ref_table = &3.
ls_fieldcat-ref_field = &4.
APPEND ls_fieldcat TO gt_fieldcat.
CLEAR ls_fieldcat.
END-OF-DEFINITION.
%%append_fieldcat:
'CHECKBOX' '选择' '' '',
'MATNR' '' 'MARA' 'MATNR',
'MTART' '' 'MARA' 'MTART', ' MAKTX '' power '' MAKTX '
'MATKL' 'Mara' MATKL ',
'CONTEXT' 'drop-down input. 1' '' ''.
The READ TABLE gt_fieldcat Assigning the FIELD-SYMBOL (<FS1>) = the WITH KEY fieldName 'the CONTEXT'.
The IF SY-SUBRC the EQ of 0. The

ENDIF. |
3. Set the drop-down box contents
Below, set_drop_down_table () method is called before the required set_table_for_first_display () method, or drop-down box does not pull down values.
Handle = 1 is the packet to the drop-down box

lt_drop_down TYPE lvc_t_drop.
"句柄HANDLE 为I类型，相同数字为同一组下拉框

CLEAR ls_drop_down.
ls_drop_down-handle = '1'.“对应分组标识
ls_drop_down-value = sy-index.
APPEND ls_drop_down TO lt_drop_down.

4.有多个下拉框分组的时候效果：
这样应该理解了handle = 1 / 2 时分组的概念了。
