LISTBOX GET HIERARCHY ( {* ;} object ; hierarchical {; hierarchy} )
| Parameter | Type | Description | |
|---|---|---|---|
| * | Operator | → | If specified, object is an object name (string) If omitted, object is a variable |
| object | any | → | Object name (if * is specified) or Variable (if * is omitted) |

Description
The LISTBOX GET HIERARCHY command lets you find out the hierarchical properties of the list box object designated by the object and * parameters.
If you pass the optional * parameter, you indicate that the object parameter is an object name (string). If you do not pass this parameter, you indicate that the object parameter is a variable. In this case, you pass a variable reference instead of a string.
The Boolean hierarchical parameter indicates whether or not the list box is in hierarchical mode:
- if the parameter returns True, the list box is in hierarchical mode,
- if the parameter returns False, the list box is displayed in non-hierarchical mode (standard array mode).
If the list box is in hierarchical mode, the command fills the hierarchy array with pointers to the arrays of the list box used to set the hierarchy.
Note: If the list box is in non-hierarchical mode, the command returns, in the first element of the hierarchy array, a pointer to the array of the first column of the list box.
