MARK(flag)

MARK	Enables multiple items selection.
flag	The label of a QUEUE field.

The MARK attribute (PROP:MARK, Write Queue Field; Read returns True/False) enables multiple item selections from a LIST or COMBO control. When an item in the LIST is selected, the appropriate flag field is set to true (1). Each marked entry is automatically highlighted in the LIST or COMBO. Changing the value of the flag field also changes the screen display for the related LIST or COMBO entry.

If the MARK attribute is specified on the LIST or COMBO, the IMM attribute may not be.

MARK can be used with a VLB List if a FROM(Queue) and MARK(Q.MarkFlag) are specified. The List data comes from the VLB but the marking updates the Q.MarkFlag.

Example:

Que1    QUEUE
MarkFlag BYTE
F1       LONG
F2       STRING(8)
        END
WinOne WINDOW,AT(0,0,160,400),SYSTEM
          LIST,AT(120,0,20,20),USE(?L1),FROM(Que1.F1),MARK(Que1.MarkFlag)
          COMBO(@S8),AT(120,120,,),USE(?C1),FROM(Que1.F2),MARK(Que1.MarkFlag)
         END
 CODE
   DO LoadQue                   !Load Que1 with data
   OPEN(WinOne)
   ACCEPT
   CASE EVENT()
    OF EVENT:CloseWindow
     BREAK
    END
   END
   LOOP X# = 1 to RECORDS(Que1) !Loop through queue entries
    GET(Que1,X#)
    IF Que1.MarkFlag            !If the user marked the entry
     DO ProcessMarked           ! then process it
    END
   END
  !*******Use of PROP:MARK
  ?List{Prop:Mark} = ''         ! clears marking
  ?List{Prop:Mark} = SFQ:Mark   ! set the field
  IF ?List{Prop:Mark} = True THEN  ! Read PROP:Mark  
     Message('LIST has Marking')  
  END
