<Result> = <Looper control>.AddLine()
<Result>: Integer
Number of the added row.
<Looper control>: Control name
Name of the Looper control to be used.
Remarks

Use conditions

<Looper>.AddLine can be used on:
  • a Looper control based on a data file,
  • a Looper control populated programmatically.

Adding an empty row

After adding an empty row, each attribute or control must be initialized individually.
For example:

Characteristics of the row

  • If a value corresponds to the result of a calculation, the numeric expression must be enclosed in brackets.
    For example:
    LOOP_CalculationZone.AddLine((53+29), (83-21))
  • Formatting attributes (e. g. color) that are not specified in the row display code are automatically reset.

Position of the new row

By default, the row is added at the end of the Looper control.
If the Looper control is sorted (<Looper>.Sort), the added row is positioned in the Looper control according to the current sort.
