- Gdk::BLANK_CURSOR (Blank cursor). Since 2.16

Since gtkmm 2.2:

Parameters:

  display | The Gdk::Display for which the cursor will be created.
  cursor_type | Cursor to create.

Returns:
  A new Gdk::Cursor.

static Glib::RefPtr<Cursor> Gdk::Cursor::create | ( | const Glib::RefPtr< Display >& | display,
|  | const Glib::RefPtr< Pixbuf >& | pixbuf,
|  | int | x,
|  | int | y
| ) |  | `[static]`

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 gtkmm 3.0:
  )

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

Since gtkmm 2.4:

Parameters:

  display | The Gdk::Display for which the cursor will be created.
  pixbuf | The Gdk::Pixbuf 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 Gdk::Cursor.

static Glib::RefPtr<Cursor> Gdk::Cursor::create | ( | const Glib::RefPtr< Display >& | display,
|  | const Glib::ustring & | name
| ) |  | `[static]`

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

Since gtkmm 2.8:

Parameters:

  display | The Gdk::Display for which the cursor will be created.
  name | The name of the cursor.

Returns:
  A new Gdk::Cursor, or `0` if there is no cursor with the given name.

CursorType Gdk::Cursor::get_cursor_type | ( |  | ) | const

Returns the cursor type for this cursor.

Since gtkmm 2.22:

Returns:
  A Gdk::CursorType.

Glib::RefPtr<Display> Gdk::Cursor::get_display | ( |  | ) |

Returns the display on which the Gdk::Cursor is defined.

Since gtkmm 2.2:

Returns:
  The Gdk::Display associated to cursor.

Glib::RefPtr<const Display> Gdk::Cursor::get_display | ( |  | ) | const

Returns the display on which the Gdk::Cursor is defined.

Since gtkmm 2.2:

Returns:
  The Gdk::Display associated to cursor.

Glib::RefPtr<Gdk::Pixbuf> Gdk::Cursor::get_image | ( |  | ) |

Returns a Gdk::Pixbuf 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, `0` is returned.

Since gtkmm 2.8:

Returns:
  A Gdk::Pixbuf representing cursor, or `0`.

Glib::RefPtr<const Gdk::Pixbuf> Gdk::Cursor::get_image | ( |  | ) | const

Returns a Gdk::Pixbuf 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, `0` is returned.

Since gtkmm 2.8:

Returns:
  A Gdk::Pixbuf representing cursor, or `0`.

GdkCursor* Gdk::Cursor::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::ObjectBase.

const GdkCursor* Gdk::Cursor::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::ObjectBase.

GdkCursor* Gdk::Cursor::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

## Friends And Related Function Documentation

Glib::RefPtr< Gdk::Cursor > wrap | ( | GdkCursor * | object,
|  | bool | take_copy = `false`
| ) |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
