## Detailed Description

Cursor defines the appearance of a system cursor.

Warning
  Features related to Cursor are not supported on iOS and Android.

This class abstracts the operating system resources associated with either a native system cursor or a custom cursor.

After loading the cursor the graphical appearance with either loadFromPixels() or loadFromSystem(), the cursor can be changed with sf::Window::setMouseCursor().

The behaviour is undefined if the cursor is destroyed while in use by the window.

Usage example:

sf::Window window;
// ... create window as usual ...
sf::Cursor cursor;
if (cursor.loadFromSystem(sf::Cursor::Hand))
window.setMouseCursor(cursor);

## Member Enumeration Documentation

## ◆ Type

enum sf::Cursor::Type

Enumeration of the native system cursor types.

Refer to the following table to determine which cursor is available on which platform.

Type | Linux | Mac OS X | Windows
--- | --- | --- | ---
sf::Cursor::Arrow | yes | yes | yes
sf::Cursor::ArrowWait | no | no | yes
sf::Cursor::Wait | yes | no | yes
sf::Cursor::Text | yes | yes | yes
sf::Cursor::Hand | yes | yes | yes
sf::Cursor::SizeHorizontal | yes | yes | yes
sf::Cursor::SizeVertical | yes | yes | yes
sf::Cursor::SizeTopLeftBottomRight | no | yes* | yes

sf::Cursor::SizeAll | yes | no | yes
sf::Cursor::Cross | yes | yes | yes
sf::Cursor::Help | yes | yes* | yes
sf::Cursor::NotAllowed | yes | yes | yes

- These cursor types are undocumented so may not be available on all versions, but have been tested on 10.13

## Constructor & Destructor Documentation

## ◆ Cursor()

sf::Cursor::Cursor | ( |  | ) |

Default constructor.

This constructor doesn't actually create the cursor; initially the new instance is invalid and must not be used until either loadFromPixels() or loadFromSystem() is called and successfully created a cursor.

## ◆ ~Cursor()

sf::Cursor::~Cursor | ( |  | ) |

Destructor.

This destructor releases the system resources associated with this cursor, if any.

## Member Function Documentation

## ◆ loadFromPixels()

bool sf::Cursor::loadFromPixels | ( | const Uint8 * | pixels,
|  | Vector2u | size,
|  | Vector2u | hotspot )

Create a cursor with the provided image.

pixels must be an array of width by height pixels in 32-bit RGBA format. If not, this will cause undefined behavior.

If pixels is null or either width or height are 0, the current cursor is left unchanged and the function will return false.

In addition to specifying the pixel data, you can also specify the location of the hotspot of the cursor. The hotspot is the pixel coordinate within the cursor image which will be located exactly where the mouse pointer position is. Any mouse actions that are performed will return the window/screen location of the hotspot.

Warning
  On Unix, the pixels are mapped into a monochrome bitmap: pixels with an alpha channel to 0 are transparent, black if the RGB channel are close to zero, and white otherwise.

Parameters

  pixels | Array of pixels of the image
  size | Width and height of the image
  hotspot | (x,y) location of the hotspot

Returns
  true if the cursor was successfully loaded; false otherwise

## ◆ loadFromSystem()

bool sf::Cursor::loadFromSystem | ( | Type | type | ) |

Create a native system cursor.

Refer to the list of cursor available on each system (see sf::Cursor::Type) to know whether a given cursor is expected to load successfully or is not supported by the operating system.

Parameters

  type | Native system cursor type

Returns
  true if and only if the corresponding cursor is natively supported by the operating system; false otherwise
