Member Function Documentation

virtual void IliTreeClassesGadget::build

(

)

[virtual]

Builds the tree, then displays it.

If your list of classes or the data of a class changes, you must call this function to rebuild the tree. This function calls the function getClassesList to build the list of classes.

void IliTreeClassesGadget::enableExpand

(

IlBoolean

enable

)

Enables or disables the display of data for the classes.

Parameters:

enable

The display is enabled if the value is IlTrue.

virtual char** IliTreeClassesGadget::getClassesList

(

IlInt &

count

)

[virtual]

Returns the class names list.

By default, this function calls the defined callback if there is one.

Parameters:

count

Contains the number of classes.

Returns:

The list of class names.

IliGetClassesListCallback IliTreeClassesGadget::getClassesListCallback

(

)

const

Returns the callback used to get the list of classes.

Returns:

The callback.

IlAny IliTreeClassesGadget::getClassesListCallbackData

(

)

const

Returns the user data used to get the list of classes.

Returns:

The user data.

virtual char** IliTreeClassesGadget::getDataList	(	const char *	cl,
		IlInt &	count
	)			[virtual]

Returns the list of data for a class.

By default, this function calls the defined callback if there is one. This function is called when you expand a class for the first time.

Parameters:

	cl	The class name
	count	Contains the number of data.

Returns:

The list of data.

IliGetDataListCallback IliTreeClassesGadget::getDataListCallback

(

)

const

Returns the callback used to get the list of data for a class.

Returns:

The callback.

IlAny IliTreeClassesGadget::getDataListCallbackData

(

)

const

Returns the user data used to get the list of data for a class.

Returns:

The user data.

IliTreeEventCallback IliTreeClassesGadget::getDragDropCallback

(

)

Returns the callback used to handle the drag-and-drop event.

Returns:

The callback.

IlAny IliTreeClassesGadget::getDragDropCallbackData

(

)

Returns the user data used to handle the drag-and-drop event.

Returns:

The user data.

IlBoolean IliTreeClassesGadget::isExpandEnabled

(

)

const

Returns the display status of data for the classes.

The default value is IlTrue.

Returns:

The display status.

void IliTreeClassesGadget::setClassesListCallback	(	IliGetClassesListCallback	cb,
		IlAny	any = 0
	)

void IliTreeClassesGadget::setDataListCallback	(	IliGetDataListCallback	cb,
		IlAny	any = 0
	)

Sets the callback used to get the list of data for a class.

Parameters:

	cb	The callback.
	any	The user data.

void IliTreeClassesGadget::setDragDropCallback	(	IliTreeEventCallback	cb,
