Declaration of the IlvGadgetItem and related classes

Macro Definition Documentation

#define DeclareGadgetItemInfo

(

)

Use this macro to declare the input/output routines of your gadget item subclass readItem, write, and copy.

See also

DeclareGadgetItemInfoRO(), DeclareGadgetItemIOConstructors().

#define DeclareGadgetItemInfoRO

(

)

Use this macro to declare the input/output routines of your gadget item subclass when you do not need to add the write member function (that is, your gadget item subtype do not add any new data that needs to be saved, and the implementation of the write member function in the parent class already does the job).

DeclareGadgetItemInfo(), DeclareGadgetItemIOConstructors().

#define DeclareGadgetItemIOConstructors

(

classname

)

Use this macro to declare the input/output constructors of your gadget item subclass.

Parameters

classname

The class name.

#define IlvPredefinedGadgetItemIOMembers

(

classname

)

Use this macro to provide a default implementation for the IlvGadgetItem::copy() and IlvGadgetItem::readItem member functions of the IlvGadgetItem subclass.

Parameters

classname

The name of the class.

DeclareGadgetItemIOConstructors(), DeclareGadgetItemInfo().

#define IlvRegisterGadgetItemClass	(		classname,
			superclass
	)

Use this macro to register your subclass of IlvGadgetItem.

Parameters

classname	The name of the class being registered.
superclass	The superclass of classname.

Typedef Documentation

IlvApplyGadgetItem

Defines the type of the function used by the IlvGadgetItemHolder::applyToItems() method.

Parameters

item	The item on which the function is invoked.
arg	The argument passed to the function.

Returns

The function should return IlFalse to stop the apply mechanism, or IlTrue to continue.

See also

IlvGadgetItemHolder::applyToItems().

IlvListCompareFunction

Defines the type of the function used by the sorting algorithm of the IlvListGadgetItemHolder to compare two items.

Parameters

string1	The label of the first item.
string2	The label of the second item.
value1	The client data of the first item.
value2	The client data of the second item.
