Member variable XbpBrowse():posBlock

Code block returning the logical position of the record pointer.

Attribute: EXPORTED

Data type: Code block

A code block must be assigned to the instance variable :posBlock. It returns a numeric value that indicates the logical position of the record pointer. The return value is used to position the scroll box of the vertical scroll bar. Refer to :goPosBlock for an example.

The vertical scroll bar is displayed by an XbpScrollBar object. The range of values that can be processed, or scrolled, is limited by the operating system. If the number of records in a database exceeds the upper limit of an XbpScrollBar object, the record pointer position must be scaled to match the maximum value recognized by an XbpScrollBar object.
