Syntax

Displaying a Looper control from a specific row Hide the details

LooperPosition(<Looper control> , <Subscript>)

<Looper control>: Control name

Name of Looper control to use.
If this parameter corresponds to an empty string (""), the Looper control used is the Looper control to which the current event belongs.
Caution: No linear Looper control can be used.

<Subscript>: Integer

Subscript of row that will be displayed at the top of Looper control.
The last row is selected by default if this parameter is greater than the number of rows found in the Looper control (returned by LooperCount).

Finding out the subscript of first row displayed in a Looper control Hide the details

<Result> = LooperPosition(<Looper control>)

<Result>: Integer

Subscript of first row displayed in the specified Looper control.

<Looper control>: Control name

Name of Looper control to use.
If this parameter corresponds to an empty string (""), the Looper control used is the Looper control to which the current event belongs.
Caution: No linear Looper control can be used.

Remarks

Selection bar and LooperPosition function

LooperPosition does not change the current row (i.e. the row selected with the selection bar).

Therefore, if the Looper control has focus when LooperPosition is run, the current row and the specified row must be visible at the same time. If the current row and the specified row cannot be displayed at the same time, the Looper control will be displayed from the current row (and not from the row specified by <Subscript>).

Displaying a row at the top of the Looper control (syntax 1)

The row displayed at the top of the looper may differ from the requested one. Indeed, LooperPosition tries to display as many rows as possible in the Looper control.

LooperPosition will display the specified row only if this row is followed by a sufficient number of non-empty rows.

Use conditions

LooperPosition can only be used in a standard Looper control without scrollbar.
