class _XTP_EXT_CLASS CXTPPropertyGridItemBool : public CXTPPropertyGridItem
{
public:

	//-----------------------------------------------------------------------
	// Summary:
	//     Constructs a CXTPPropertyGridItemBool object.
	// Parameters:
	//     strCaption - Caption of the item.
	//     nID        - Identifier of the item.
	//     bValue     - Initial value of item.
	//     pBindBool  - If not NULL, then the value of this item
	// Remarks:
	//     Class CXTPPropertyGridItemBool has no default constructor.
	//
	//     When using the second constructor, the Identifier (nID) of the
	//     second constructor can be linked with a STRINGTABLE resource
	//     with the same id in such form "Caption\\nDescription".
	//
	//     BINDING:
	//     Variables can be bound to an item in two ways, the first is
	//     to pass in a variable at the time of creation, the second allows
	//     variables to be bound to an item after creation with the
	//     BindToBool member.
	//
	//     Bound variables store the values of the property grid items
	//     and can be accessed without using the property grid methods
	//     and properties.  Bound variables allow the property grid to
	//     store data in variables.  When the value of a PropertyGridItem
	//     is changed, the value of the bound variable will be changed to
	//     the PropertyGridItem value.  The advantage of binding is that
	//     the variable can be used and manipulated without using
	//     PropertyGridItem methods and properties.
	//
	//     NOTE:  If the value of the variable is changed without using
	//     the PropertyGrid, the PropertyGridItem value will not be
	//     updated until you call CXTPPropertyGrid::Refresh.

//===========================================================================
// Summary:
//     CXTPPropertyGridItemEnum is a CXTPPropertyGridItem derived class.
//     It is used to create an Enum value item in a Property Grid control.
// Remarks:
//     A Enum item is used to display a list of constraints.  This is
//     very similar to a normal constraint list.  The difference is that
//     an Enum constraint list will return the Value of the constraint when
//     selected, where a normal constraint wold return the text of the
//     constraint.
//
// Example:
//     This code illustrates how to add an item of type Enum to your grid.
// <code>
// //Adds a category to the grid called "Software"
// CXTPPropertyGridItem* pStandard   = m_wndPropertyGrid.AddCategory(_T("Software"));
//
// //Adds a CXTPPropertyGridItemFlags item with a caption of "Current OS" and an initial value of 2
// //This will cause the constraint with a value of 2 to be selected
// CXTPPropertyGridItemEnum* pItem = (CXTPPropertyGridItemEnum*)(pStandard->AddChildItem(new CXTPPropertyGridItemEnum(_T("Current OS"), 2)));
//
// //Adds some constraints along with a value
// pItem->GetConstraints()->AddConstraint(_T("Windows 98"), 1);
// pItem->GetConstraints()->AddConstraint(_T("Windows 2000"), 2);
// pItem->GetConstraints()->AddConstraint(_T("Windows XP"), 3);
//
// //GetEnum will return the Data value of the constraint selected
// TRACE(_T("Enum Item Value= %d\n"), pItem->GetEnum());
//
// //GetValue will return the String of the constraint selected
// TRACE(_T("Enum Item String= %s\n"), pItem->GetValue());
// </code>

//===========================================================================
// Summary:
//     CXTPPropertyGridItemFlags is a CXTPPropertyGridItem derived class.
//     It is used to create a Flags value item in a Property Grid control.
// Remarks:
//     A flag item is used to combine multiple boolean values into a
//     single item.  When using a flag item, you must add constraints
//     to the flag item.  Each constraint will have a value of TRUE or
//     FALSE.  The flag item will have an expand button that when clicked
//     will display all boolean constraints for that item.  The value of
//     the flag item will be the sum of all the boolean constraints with
//     a value of TRUE.
//
//          NOTE: Constraint values must be in powers of 2 if you will have an
//                "All" constraint that indicates that the value of all boolean
//                 constraints is TRUE or FALSE.
//
//          In the example below, the flag item's initial value will be 9, this
//          value is stored in CXTPPropertyGridItemFlags::m_nValue and can be
//          set with SetFlags and retrieved with GetFlags.  The string value will
//          be "[Windows 98; Windows 95]" and this value is stored in
//          CXTPPropertyGridItem::m_strValue, which can be retrieved
//          with CXTPPropertyGridItem::GetValue.  You must use the SetFlags method
//          to change the flag items value by code.  The string value is what is
//          displayed to the user.
//
// Example:
// This sample illustrates how to add an item of type Flags to your grid.
// <code>
// //Adds a category to the grid called "Software"
// CXTPPropertyGridItem* pStandard   = m_wndPropertyGrid.AddCategory(_T("Software"));
//
// //Adds a CXTPPropertyGridItemFlags item with a caption of "Supported OS" and an initial value of 9
// CXTPPropertyGridItemFlags* pItem = (CXTPPropertyGridItemFlags*)(pStandard->AddChildItem(new CXTPPropertyGridItemFlags(_T("Supported OS"), 1 + 8)));
//
// //Adds a constraint that will set all items TRUE or FALSE, note the value of the constraint is the sum
// //of all the other constraints.  This item will also be updated when the values of the other constraints
// //have changed.
// pItem->GetConstraints()->AddConstraint(_T("All Windows"), 1 + 2 + 4 + 8 + 16 + 32);
//
// //Adds a constraint that can have a value of TRUE or FALSE
// pItem->GetConstraints()->AddConstraint(_T("Windows 98"), 1);
// pItem->GetConstraints()->AddConstraint(_T("Windows 2000"), 2);
// pItem->GetConstraints()->AddConstraint(_T("Windows XP"), 4);
// pItem->GetConstraints()->AddConstraint(_T("Windows 95"), 8);
// pItem->GetConstraints()->AddConstraint(_T("Windows NT"), 16);
// pItem->GetConstraints()->AddConstraint(_T("Windows 2003"), 32);
//
// //This changes the value of the flag item to 21 and the string
// //caption to [Windows 98; Windows XP; Windows NT]
// pItem->SetFlags(21);
//
// //GetFlags will return the sum of all true constraints
// TRACE(_T("Flags Item Value= %d\n"), pItem->GetFlags());
//
// //GetValue will return a string containing the text of all true constraints
// TRACE(_T("Flags Item String= %s\n"), pItem->GetValue());

	//          BINDING:
	//            Variables can be bound to an item in two ways, the first is
	//            to pass in a variable at the time of creation, the second allows
	//            variables to be bound to an item after creation with the
	//            BindToFlags member.
	//
	//            Bound variables store the values of the property grid items
	//            and can be accessed without using the property grid methods
	//            and properties.  Bound variables allow the property grid to
	//            store data in variables.  When the value of a PropertyGridItem
	//            is changed, the value of the bound variable will be changed to
	//            the PropertyGridItem value.  The advantage of binding is that
	//            the variable can be used and manipulated without using
	//            PropertyGridItem methods and properties.
	//
	//            NOTE:  If the value of the variable is changed without using
	//            the PropertyGrid, the PropertyGridItem value will not be
	//            updated until you call CXTPPropertyGrid::Refresh.
