## Properties

      "cursor-type"              GdkCursorType         : Read / Write / Construct Only
      "display"                  GdkDisplay*           : Read / Write / Construct Only

## 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 struct passed to `gdk_window_new()`.

## Details

### GdkCursor

    typedef struct _GdkCursor GdkCursor;

The GdkCursor structure represents a cursor. Its contents are private.

### 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`.

`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.

`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.

`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);

Creates a new cursor from the set of builtin cursors. Some useful ones are:

- GDK_RIGHT_PTR (right-facing arrow)

- GDK_CROSSHAIR (crosshair)

- GDK_XTERM (I-beam)

- GDK_WATCH (busy)

- GDK_FLEUR (for moving objects)

- GDK_HAND1 (a right-pointing hand)

- GDK_HAND2 (a left-pointing hand)

- GDK_LEFT_SIDE (resize left side)

- GDK_RIGHT_SIDE (resize right side)

- GDK_TOP_LEFT_CORNER (resize northwest corner)

- GDK_TOP_RIGHT_CORNER (resize northeast corner)

- GDK_BOTTOM_LEFT_CORNER (resize southwest corner)

- GDK_BOTTOM_RIGHT_CORNER (resize southeast corner)

- GDK_TOP_SIDE (resize top side)

- GDK_BOTTOM_SIDE (resize bottom side)

- GDK_SB_H_DOUBLE_ARROW (move vertical splitter)

- GDK_SB_V_DOUBLE_ARROW (move horizontal splitter)

- GDK_BLANK_CURSOR (Blank cursor). Since 2.16

`display` : | the GdkDisplay for which the cursor will be created
`cursor_type` : | cursor to create
Returns : | a new GdkCursor

Since 2.2

### gdk_cursor_get_display ()

    GdkDisplay *        gdk_cursor_get_display              (GdkCursor *cursor);

Returns the display on which the GdkCursor is defined.

`cursor` : | a GdkCursor.
Returns : | the GdkDisplay associated to `cursor`. [transfer none]

Since 2.2

### gdk_cursor_get_image ()

    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`. [transfer full]

Since 2.8

### gdk_cursor_get_cursor_type ()

    GdkCursorType       gdk_cursor_get_cursor_type          (GdkCursor *cursor);

Returns the cursor type for this cursor.

`cursor` : | a GdkCursor
Returns : | a GdkCursorType

Since 2.22

### gdk_cursor_ref ()

    GdkCursor *         gdk_cursor_ref                      (GdkCursor *cursor);

### Warning

`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`.

`cursor` : | a GdkCursor
Returns : | Same `cursor` that was passed in. [transfer full]

### gdk_cursor_unref ()

    void                gdk_cursor_unref                    (GdkCursor *cursor);

### Warning

`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.

`cursor` : | a GdkCursor
