Helper class for managing choices of wxPropertyGrid properties.
Each entry can have label, value, bitmap, text colour, and background
colour.
+
+ wxPGChoices uses reference counting, similar to other wxWidgets classes.
+ This means that assignment operator and copy constructor only copy the
+ reference and not the actual data. Use Copy() member function to create a
+ real copy.
@remarks If you do not specify value for entry, index is used.
