MVI_PROP (tag)

Parameters

tag
The property tag to be modified.

Remarks

The MVI_FLAG combines the setting of MV_FLAG, identifying a property as multivalued, and MV_INSTANCE, requesting that a multivalued property be displayed in a table in multiple rows. The property type of the affected property is modified, but the identifier remains unchanged.

For example, when the MVI_PROP macro is applied to a property of type PT_FLOAT, its type is changed to PT_MV_FLOAT. When included in a table, multiple rows are used to represent the property with one row for each value. The properties for the other columns are repeated.
