Overview

 Provides column objects for TBrowse objects

Description

     A TBColumn object is a simple object containing the information needed
     to fully define one data column of a TBrowse object (see the TBrowse
     reference in this chapter).  TBColumn objects have no methods, only
     exported instance variables.

Examples

     .  This example is a code fragment that creates a TBrowse object
        and adds some TBColumn objects to it:

        USE Customer NEW
        //

        // Create a new TBrowse object
        objBrowse := TBrowseDB(1, 1, 23, 79)
        //

        // Create some new TBColumn objects and
        // add them to the TBrowse object
        objBrowse:addColumn(TBColumnNew( "Customer", ;
              {|| Customer->Name} ))
        objBrowse:addColumn(TBColumnNew( "Address", ;
              {|| Customer->Address} ))
        objBrowse:addColumn(TBColumnNew( "City", ;
              {|| Customer->City} ))
        .
        . <statements to actually browse the data>
        .
        CLOSE Customer

        For more information on TBrowse, refer to the Introduction to TBrowse
        chapter in the Programming and Utilitites guide.  For a fully
        operational example of a TBrowse object, see also TbDemo.prg located
        in \CLIPPER5\SOURCE\SAMPLE.

Class Function
     TBColumnNew()   Create a new TBColumn object

     TBColumnNew(<cHeading>, <bBlock>) --> objTBColumn

        Returns a new TBColumn object with the specified heading and data
        retrieval block.  Other elements of the TBColumn object can be
        assigned directly using the syntax for assigning exported instance
        variables.
