/////////////////////////////////////////////////////////////////////////////
// The CCellEdit class.
//
// This class implements the core of the grid cell editor.  The grid cell editor
// is made up of three parts, a CEdit, a CButton, and a CListBox.  The CButton
// and CListBox are used to implement the combo-drop button and enumeration list
// respectively.
//
// A standard combo-box was not used as the base class because there was no
// way to turn off the border drawing and, thus, there was no way to get the
// desired look and feel.  Also, a custom implementation gives us more flexibility.
