Syntax
Moving to a specific position Hide the details
<Result> = <List Box control>.MoveLine(<Index of row to move> , <Destination row index> [, <Operation to perform>])
<Result>: Integer New index of the row that was moved. <List Box control>: Control name Name of the List Box or Combo Box control to be used. <Index of row to move>: Integer Position of the row to move. This position must be included between 1 and the number of rows found in the List Box or Combo Box control (returned by <List Box>.Count or Occurrence for example).To move the row that is currently selected, use the rowSelected constant. <Destination row index>: Integer New row position. This position must be between 1 and the number of rows in the List Box or Combo Box control (returned by <List Box>.Count or Occurrence, for example). A fatal error occurs if this parameter is not valid.To handle the row that is currently selected, use the rowSelected constant. <Operation to perform>: Optional Integer constant (or combination of constants) Change row position: | | | amDisplayDestination | The modified row is displayed in the List Box control (or Combo Box). If necessary, the lines are dequeued automatically to display the modified line. The selected row (selection bar) does not change.
This constant can be combined with the amMove and amSwap constants.
| amMove
(default value) | Moves the row to the index of the destination row. | | amSwap | The source and destination rows are swapped. |
Moving relatively to the current position Hide the details
<Result> = <List Box control>.MoveLine(<Index of row to move> , <Relative move> [, <Operation to perform>])
<Result>: Integer - New index of the row that was moved,
- 0 if an error occurs.
<List Box control>: Control name Name of List Box control to use. <Index of row to move>: Integer Position of the row to move. This position must be included between 1 and the number of rows in the List Box control (returned by <List Box>.Count or Occurrence for example).To handle the row that is currently selected, use the rowSelected constant. <Relative move>: Integer constant Used to move or a swap to a position relative to the index of the row to move. | | | amFirst | Moves the row to the first position. | | amLast | Moves the row to the last position. | | amNext | Moves the row one position downwards. | | amNextPage | Moves the row one page to the bottom (a page corresponds to the number of rows that can be simultaneously displayed in the List Box control).
| | amPrevious | Moves the row one position upwards. | | amPreviousPage | Moves the row one page to the top (a page corresponds to the number of rows that can be simultaneously displayed in the List Box control).
|
If this parameter is invalid (amPrevious used on the first row of List Box control for example), the row is moved "to the nearest" position. <Operation to perform>: Optional Integer constant (or combination of constants) Change row position: | | | amDisplayDestination | The modified row is displayed in the List Box control. If necessary, the lines are dequeued automatically to display the modified line. The selected row (selection bar) does not change.
This constant can be combined with the amMove and amSwap constants.
| amMove
(default value) | Moves the row to the index of the destination row. | | amSwap | The source and destination rows are swapped. |
Remarks Operating mode on a Combo Box control When <List Box>.MoveLine is used on a Combo Box control, the selected element remains the same. The index of the element selected in the drop-down list (i.e. the value returned by the Combo Box control) is modified. Multi-selection List Box control If <List Box>.MoveLine is used on a multi-selection List Box control: - when moving lines (constant tdDéplace): all selected lines will be moved.
- when exchanging lines (constant tdEchange): only the first line will be exchanged.
- the rowSelected constant cannot be used. Otherwise, a fatal error occurs and no row is moved.
Error management Caution: <List Box>.MoveLine returns no error code. To determine if this function has generated an error, use ErrorInfo with the errMessage constant.
