Functions for accessing properties

The following property functions are useful for accessing SmartObject properties from application code:

The assignLinkProperty function sets a property value in one or more objects at the other end of the specified link. It is defined as follows:

assignLinkProperty RETURNS LOGICAL (pcLink AS CHARACTER, pcPropName AS CHARACTER, pcPropValue AS CHARACTER):

For example, the following code in a SmartDataObject uses assignLinkProperty to set the DataModified property to yes in all its Data-Targets:

DYNAMIC-FUNCTION(‘assignLinkProperty’:U, INPUT "DATA-TARGET":U, INPUT "DataModified":U, INPUT "yes":U).

The linkProperty function returns the value of the specified property in the single object at the other end of the specified link. It is defined as follows:

linkProperty RETURNS CHARACTER (pcLink AS CHARACTER, pcPropName AS CHARACTER):

For example, the following code in a visual object (a SmartDataViewer or a SmartDataBrowser) uses linkProperty to get the current page of the object’s container:

iCurrentPage = DYNAMIC-FUNCTION(‘linkProperty’:U, INPUT "CONTAINER-SOURCE":U, INPUT "CurrentPage":U).

The propertyType function returns the data type of the specified property. It is defined as follows:

propertyType RETURNS CHARACTER (pcPropName AS CHARACTER):

For example, the following code in a SmartDataObject gets the data type of its DataQueryBrowsed property:

cDataType = DYNAMIC-FUNCTION(‘propertyType’:U IN h_dcustomer, INPUT "DataQueryBrowsed":U).

This function returns data types only for properties for which a setpropname function is defined.
