## Description

## Functions

### gdk_cursor_new ()

    GdkCursor *
    gdk_cursor_new (GdkCursorType cursor_type);

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_pixmap ()

    GdkCursor *
    gdk_cursor_new_from_pixmap (GdkPixmap *source,
                                GdkPixmap *mask,
                                const GdkColor *fg,
                                const GdkColor *bg,
                                gint x,
                                gint y);

Creates a new cursor from a given pixmap and mask. Both the pixmap and mask must have a depth of 1 (i.e. each pixel has only 2 values - on or off). The standard cursor size is 16 by 16 pixels. You can create a bitmap from inline data as in the below example.

     source = gdk_bitmap_create_from_data (NULL, cursor1_bits,

     cursor = gdk_cursor_new_from_pixmap (source, mask, &fg, &bg, 8, 8);
     g_object_unref (source);
     g_object_unref (mask);

     gdk_window_set_cursor (widget->window, cursor);

#### Parameters

source | the pixmap specifying the cursor. |
mask | the pixmap specifying the mask, which must be the same size as `source` . |
fg | the foreground color, used for the bits in the source which are 1. The color does not have to be allocated first. |
bg | the background color, used for the bits in the source which are 0. The color does not have to be allocated first. |
x | the horizontal offset of the 'hotspot' of the cursor. |
y | the vertical offset of the 'hotspot' of the cursor. |

#### 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_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.

#### Parameters

display | the GdkDisplay for which the cursor will be created |
name | the name of the cursor |

#### Returns

a new GdkCursor, or `NULL` if there is no cursor with the given name

Since: 2.8

### gdk_cursor_new_for_display ()

    GdkCursor *
    gdk_cursor_new_for_display (GdkDisplay *display,
                                GdkCursorType cursor_type);

    gdk_cursor_get_display (GdkCursor *cursor);

Returns the display on which the GdkCursor is defined.

#### Parameters

    GdkPixbuf *
    gdk_cursor_get_image (GdkCursor *cursor);

Returns a GdkPixbuf with the image used to display the cursor.

Note that depending on the capabilities of the windowing system and on the cursor, GDK may not be able to obtain the image data. In this case, `NULL` is returned.

cursor | a GdkCursor |

#### Returns

a GdkPixbuf representing `cursor` , or `NULL`

Since: 2.8

### gdk_cursor_get_cursor_type ()

### gdk_cursor_ref ()

    GdkCursor *
    gdk_cursor_ref (GdkCursor *cursor);

Adds a reference to `cursor` .

cursor | a GdkCursor |

Same `cursor` that was passed in.

[transfer full]

### gdk_cursor_unref ()

    void
