The command PV SET DOCUMENT PROPERTY allows developers to restrict access to 4D View documents. The command takes three parameters, a 4D View area, an option, as well as a value. There are four available options, all relating to access of a 4D View document:

• pv column count (0) - Set the number of visible columns


• pv row count (1) - Set the number of visible rows


• pv no external call (3) - Set whether calls to 4D variables, methods and commands are forbidden in the formula area or not


• pv document modified (4) - Sets whether the 4D View document can be modified

Below is an example of what a 4D View document may look like:

Now, here is an example of the same document that restricts the visible area to show the first 2 columns and only the first 3 rows:

PV SET DOCUMENT PROPERTY (Plugin Area;pv column count;2) PV SET DOCUMENT PROPERTY (Plugin Area;pv row count;3)
