## Description

These functions are used to create and destroy cursors. There is a number of standard cursors, but it is also possible to construct new cursors from pixbufs. There may be limitations as to what kinds of cursors can be constructed on a given display, see `gdk_display_supports_cursor_alpha()`, `gdk_display_supports_cursor_color()`, `gdk_display_get_default_cursor_size()` and `gdk_display_get_maximal_cursor_size()`.

Cursors by themselves are not very interesting, they must be be bound to a window for users to see them. This is done with `gdk_window_set_cursor()` or by setting the cursor member of the GdkWindowAttr passed to `gdk_window_new()`.

## Functions

### gdk_cursor_new ()

    GdkCursor *
    gdk_cursor_new (GdkCursorType cursor_type);

`gdk_cursor_new` has been deprecated since version 3.16 and should not be used in newly-written code.

Use `gdk_cursor_new_for_display()` instead.

Creates a new cursor from the set of builtin cursors for the default display. See `gdk_cursor_new_for_display()`.

To make the cursor invisible, use `GDK_BLANK_CURSOR`.

#### Parameters

cursor_type | cursor to create |

#### Returns

a new GdkCursor

### gdk_cursor_new_from_pixbuf ()

    GdkCursor *
    gdk_cursor_new_from_pixbuf (GdkDisplay *display,
                                GdkPixbuf *pixbuf,
                                gint x,
                                gint y);

Creates a new cursor from a pixbuf.

Not all GDK backends support RGBA cursors. If they are not supported, a monochrome approximation will be displayed. The functions `gdk_display_supports_cursor_alpha()` and `gdk_display_supports_cursor_color()` can be used to determine whether RGBA cursors are supported; `gdk_display_get_default_cursor_size()` and `gdk_display_get_maximal_cursor_size()` give information about cursor sizes.

If `x` or `y` are `-1`, the pixbuf must have options named “x_hot” and “y_hot”, resp., containing integer values between `0` and the width resp. height of the pixbuf. (Since: 3.0)

On the X backend, support for RGBA cursors requires a sufficently new version of the X Render extension.

#### Parameters

display | the GdkDisplay for which the cursor will be created |
pixbuf | the GdkPixbuf containing the cursor image |
x | the horizontal offset of the “hotspot” of the cursor. |
y | the vertical offset of the “hotspot” of the cursor. |

#### Returns

a new GdkCursor.

Since: 2.4

### gdk_cursor_new_from_surface ()

    GdkCursor *
    gdk_cursor_new_from_surface (GdkDisplay *display,
                                 cairo_surface_t *surface,
                                 gdouble x,
                                 gdouble y);

Creates a new cursor from a cairo image surface.

Not all GDK backends support RGBA cursors. If they are not supported, a monochrome approximation will be displayed. The functions `gdk_display_supports_cursor_alpha()` and `gdk_display_supports_cursor_color()` can be used to determine whether RGBA cursors are supported; `gdk_display_get_default_cursor_size()` and `gdk_display_get_maximal_cursor_size()` give information about cursor sizes.

On the X backend, support for RGBA cursors requires a sufficently new version of the X Render extension.

#### Parameters

display | the GdkDisplay for which the cursor will be created |
surface | the cairo image surface containing the cursor pixel data |
x | the horizontal offset of the “hotspot” of the cursor |
y | the vertical offset of the “hotspot” of the cursor |

#### Returns

a new GdkCursor.

Since: 3.10

### gdk_cursor_new_from_name ()

    GdkCursor *
    gdk_cursor_new_from_name (GdkDisplay *display,
                              const gchar *name);

Creates a new cursor by looking up `name` in the current cursor theme.

A recommended set of cursor names that will work across different platforms can be found in the CSS specification:

- "none"

- "help"

- "pointer"

- "context-menu"

- "progress"

- "wait"

- "n-resize"

- "e-resize"

- "s-resize"

- "w-resize"

- "ne-resize"

- "nw-resize"

- "sw-resize"

                                GdkCursorType cursor_type);

Creates a new cursor from the set of builtin cursors.

### gdk_cursor_ref ()

    GdkCursor *
    gdk_cursor_ref (GdkCursor *cursor);

`gdk_cursor_ref` has been deprecated since version 3.0 and should not be used in newly-written code.

Use `g_object_ref()` instead

Adds a reference to `cursor` .

#### Parameters

cursor | a GdkCursor |

#### Returns

Same `cursor` that was passed in.

[transfer full]

### gdk_cursor_unref ()

    void
    gdk_cursor_unref (GdkCursor *cursor);

`gdk_cursor_unref` has been deprecated since version 3.0 and should not be used in newly-written code.

Use `g_object_unref()` instead

Removes a reference from `cursor` , deallocating the cursor if no references remain.

#### Parameters

cursor | a GdkCursor |

## Types and Values

### GdkCursor

    typedef struct _GdkCursor GdkCursor;

A GdkCursor represents a cursor. Its contents are private.

### enum GdkCursorType

Predefined cursors.

Note that these IDs are directly taken from the X cursor font, and many of these cursors are either not useful, or are not available on other platforms.

The recommended way to create cursors is to use `gdk_cursor_new_from_name()`.
