getCurrentItem()
getCurrentItem() is used to retrieve the name of the currently active form item:
LET dial = ui.Dialog.GetCurrent()
Parameters
takes no parameters
Possible values
depend on the location of the focus
- the name of the action - if the program focus is on a button or another item having the ACTION attribute;
- the name of the current field given as [tab_name.]field_name - the tab_name prefix is added to the retrieved value if a FROM clause contains an explicit list of fields. If the dialog uses FROM screen_record.* or BY NAME structures, the prefix is omitted;
- the name of the screen array - if the program focus is in an active DISPLAY ARRAY list;
- the identifier of the screen record given as screen_array.screen_record - if the program focus is in the INPUT ARRAY list. In some cases, the field name is left unidentified (e.g., in the BEFORE INPUT block of an INPUT ARRAY statement)
