Description
The LISTBOX SET PROPERTY command sets the value for the property of the list box or list box column specified using 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.
Note: If the list box or list box column specified using the object and * parameters does not exist, the command does nothing and no error is triggered.
In the property and value parameters, you indicate, respectively, the property to set and its new value. You can use the following constants found in the “List Box” theme:
