The LISTBOX Get headers height command returns the height of the header row in the list box designated by the object and * parameters.
If you pass the optional * parameter, this indicates that the object parameter is an object name (a string). If you do not pass this parameter, this indicates that the object is a variable. In this case, you pass a variable reference instead of a string. You can designate either the list box or any header of the list box.
By default, if you omit the unit parameter, the height of the row returned is expressed in pixels. To set a different unit, you can pass one of the following constants (found in the List Box theme), in the unit parameter:
| Constant | Type | Value | Comment |
| Listbox lines | Longint | 1 | Height designates a number of lines. 4D calculates the height of a line according to the font |
| Listbox pixels | Longint | 0 | Height is a number of pixels (default). |
Note: For more information about calculating the height of rows, refer to the Design Reference manual.
