Detailed Description

Application Framework document project class.

Library: ilvappframe

IlvDvProjectDocument is a subclass of IlvDvDocument The document data is a hierarchical tree of items whose class must inherit from IlvDvProjectItem class.

Project items
By default, two types of items are provided. Some items store a group of other items (IlvDvFolderItem class) represented in the project view as a folder. The other items reference a file (IlvDvFileItem class) represented in the project view as a file tree item that opens the corresponding document when it is activated.

IlvDvFileInfo objects
References to a file are objects of the class IlvDvFileInfo that contain information on the file, such as its full path. IlvDvFileInfo objects are stored by the IlvDvProjectDocument document and must be locked and unlocked when they are used or stored outside the project document, the same way project file items do. Two project file items that reference the same file point to the same IlvDvFileInfo object.

Member Function Documentation

virtual IlBoolean IlvDvProjectDocument::activateItem ( IlvDvProjectItem * item )

virtual

Activates the project item item.

By default, if the item is a file item, a document corresponding to the file path is created, or activated if it was already open.
This method can be overridden to activate its own project item types.

Returns: IlFalse if a project item could not be activated.

IlBoolean IlvDvProjectDocument::activateItems	(	IlvDvProjectItem const	items,
		IlUInt	count
	)

Activates the project items items by calling the activateItem method for each item. This method can be called by a project view if the multiple selection of tree gadget items has been activated.

Returns: IlFalse if a project item could not be activated.

virtual IlvDvDocumentProjectItem* IlvDvProjectDocument::createDocumentProjectItem ( )

protectedvirtual

Creates a document project item.

Creates a project item of a subclass of IlvDvDocumentProjectItem. This project item will be the root of the project items.
By default, it creates an IlvDvDocumentProjectItem object.

Returns: The new document project item.

virtual IlvDvProjectItem* IlvDvProjectDocument::createProjectFileItem ( IlvDvFileInfo * fileInfo )

protectedvirtual

Creates a project file item that corresponds to the parameter fileInfo. By default, it creates an IlvDvFileItem object.

virtual IlvDvProjectItem* IlvDvProjectDocument::createProjectFolderItem	(	const char *	name,
		const char *	extensions = `0`
	)

protectedvirtual

Creates a project folder item using the parameters name and extensions. By default, it creates an IlvDvFolderItem object.

Returns: The new project folder item.

IlvDvFileInfo* IlvDvProjectDocument::getFileInfo ( IlUInt index ) const

Returns the file information object located at index index.

These files are referenced by an IlvDvFileInfo object that is used by at least one project file item.

Returns: The file information located object at index index.

IlUInt IlvDvProjectDocument::getFileInfosCount ( ) const

Returns the number of files that are owned by the project document.

These files are referenced by an IlvDvFileInfo object that is used by at least one project file item.

Returns: The number of files that are owned by the project document.

IlUInt IlvDvProjectDocument::getIndexOfFileInfo ( const IlvDvFileInfo * fInfo ) const

Returns the index of the file information object fInfo from the list of file information stored by the document.

Returns: The index of the file information object.

IlvDvDocumentProjectItem* IlvDvProjectDocument::getProjectRootItem ( ) const

Returns the project root item of the document.

Returns: The project root item of the document.

virtual IlBoolean IlvDvProjectDocument::initializeDocument ( IlAny data = 0 )

virtual

Initializes a new project document.

This method creates a root project item by calling the method createDocumentProjectItem. The item represents the project document itself.

Returns: IlTrue if initialization of document succeeded.

Reimplemented from IlvDvDocument.

IlBoolean IlvDvProjectDocument::insertFile	(	IlvDvProjectItem *	parent,
		const IlPathName &	filename
	)

Inserts a file in the project.

Inserts a project file item as a child of the project item parent. The project file item is built by calling the method createProjectFileItem, which can be redefined.
Associated document views are notified when they receive the message "AddProjectItem" with the new project item as the parameter.
By default, the project views add a tree gadget item corresponding to the new project item.

Parameters

parent	Project item that will be the parent of the new project file item.
filename	Full path of the added file item.

Returns: IlTrue if the project file item is created and inserted.

IlBoolean IlvDvProjectDocument::insertFolder	(	IlvDvProjectItem *	parent,
		const char *	name,
		const char *	extensions = `0`
	)

Inserts a project folder item with the name name as a child of the project item parent.

The project folder item is built by calling method createProjectFolderItem, which can be redefined.
Associated document views are notified when they receive the message "AddProjectItem" with the new project item as the parameter.
By default, the project views add a tree gadget item corresponding to the added project item.

Parameters

parent	Project item that will be the parent of the project folder item.
name	Name of the folder.
extensions	Specifies the file extensions that filter which file items can be added to the folder items. This parameter is null by default. If it is null, all file items can be added to the folder items.

Returns: IlTrue if the project folder item is inserted.

IlBoolean IlvDvProjectDocument::insertItem	(	IlvDvProjectItem *	item,
		IlvDvProjectItem *	parent = `0`,
		IlUShort	index = `(IlUShort)-1`
	)

Inserts a project item as a child of the project item parent.

Associated document views are notified when they receive the message "AddProjectItem" with the project item item given as the parameter.
By default, the project views add a tree gadget item corresponding to the added project item.

Parameters

item	Project item that must be added to the document.
parent	Project item that will be the parent of the project file item item.
index	The position where the project item item will be inserted among the children of the project item parent.

Returns: IlTrue if the project file item is inserted.

virtual void IlvDvProjectDocument::removeTreeItemData ( IlvDvProjectItem * item )

protectedvirtual

It removes the data associated with the project item item.

Called before a project item is deleted.

void IlvDvProjectDocument::removeTreeItems	(	IlvDvProjectItem const	items,
		IlUInt	count
	)

Removes a list of project items.

The items items are destroyed. For each project item destroyed, associated document views are notified. They receive messages of the name "RemoveProjectItem" with the corresponding deleted project item as the parameter. By default, the project views (IlvDvProjectView class) remove the corresponding tree item from the tree.

Parameters

items	Array of project items to be deleted.
count	Number of project items to be deleted.

virtual void IlvDvProjectDocument::serialize ( IlvDvStream & stream )

virtual

Serializes the document.

All project items are serialized, as well as the file information data used by the project file items.

Parameters

stream Stream used to serialize the document.

Reimplemented from IlvDvDocument.

virtual void IlvDvProjectDocument::setTitle	(	const char *	title,
		IlBoolean	update = `IlTrue`
	)

virtual

Sets the title title for the document.

If the label of the project root item has not been explicitly changed, the label is set to the title.
