Class Overview

Constructor and Destructor

BCursor()

BCursor(const void* cursorData); BCursor(BMessage* archive);

Initializes the new cursor object. If you specify a non-NULL value for cursorData, the cursor is initialized with the specified cursor data.

If you specify a NULL value for cursorData, the cursor is useless; since this class doesn't currently provide a means of setting the cursor data once the object is instantiated, you're out of luck, so why bother?

BCursor doesn't currently implement archiving, so you shouldn't use the second form.

~BCursor()

virtual ~BCursor();

Releases any resources used by the cursor.

Static Functions

Instantiate()

static BArchivable* Instantiate(BMessage* archive);

Not currently implemented; always returns NULL.

Constants

Declared in: app/AppDefs.h

const unsigned char B_HAND_CURSOR[]
const unsigned char B_I_BEAM_CURSOR[]

These constants contain all the data needed to set the cursor to the default hand image or to the standard I-beam image for text selection.

const BCursor* B_CURSOR_SYSTEM_DEFAULT
const BCursor* B_CURSOR_I_BEAM

The second two constants are BCursor objects and produce the same cursors the first two constants.
