Member Function Documentation

◆ create() [1/5]

static Glib::RefPtr<Cursor> Gdk::Cursor::create ( CursorType cursor_type )

static

Creates a new cursor from the set of builtin cursors for the default display.

See new_for_display().

To make the cursor invisible, use Gdk::BLANK_CURSOR.

Deprecated: 3.16: Use new_for_display() instead.

Deprecated:: Use the constructor that takes a Display instead.

Parameters

cursor_type Cursor to create.

Returns: A new Gdk::Cursor.

◆ create() [2/5]

static Glib::RefPtr<Cursor> Gdk::Cursor::create	(	const Glib::RefPtr< Display >&	display,
		CursorType	cursor_type
	)

static

Creates a new cursor from the set of builtin cursors.

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.

◆ create() [3/5]

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: 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.

◆ create() [4/5]

static Glib::RefPtr<Cursor> Gdk::Cursor::create	(	const Glib::RefPtr< Display >&	display,
		const ::Cairo::RefPtr< ::Cairo::Surface > &	surface,
		double	x,
		double	y
	)

static

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.

Since gtkmm 3.10:

Parameters

display	The Gdk::Display 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 Gdk::Cursor.

◆ create() [5/5]

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.

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

"none"
"default"
"help"
"pointer"
"context-menu"
"progress"
"wait"
"cell"
"crosshair"
"text"
"vertical-text"
"alias"
"copy"
"no-drop"
"move"
"not-allowed"
"grab"
"grabbing"
"all-scroll"
"col-resize"
"row-resize"
"n-resize"
"e-resize"
"s-resize"
"w-resize"
"ne-resize"
"nw-resize"
"sw-resize"
"se-resize"
"ew-resize"
"ns-resize"
"nesw-resize"
"nwse-resize"
"zoom-in"
"zoom-out"

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 nullptr if there is no cursor with the given name.

◆ get_cursor_type()

CursorType Gdk::Cursor::get_cursor_type ( ) const

Returns the cursor type for this cursor.

Since gtkmm 2.22:

Returns: A Gdk::CursorType.

◆ get_display() [1/2]

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.

◆ get_display() [2/2]

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

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

Returns: The Gdk::Display associated to cursor.

◆ get_image() [1/2]

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, nullptr is returned.

Since gtkmm 2.8:

Returns: A Gdk::Pixbuf representing cursor, or nullptr.

◆ get_image() [2/2]

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, nullptr is returned.

Since gtkmm 2.8:

Returns: A Gdk::Pixbuf representing cursor, or nullptr.

◆ get_surface() [1/2]

::Cairo::RefPtr< ::Cairo::Surface> Gdk::Cursor::get_surface	(	double &	x_hot,
		double &	y_hot
	)

Returns a cairo image surface 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, nullptr is returned.

Since gtkmm 3.10:

Parameters

x_hot	Location to store the hotspot x position, or `nullptr`.
y_hot	Location to store the hotspot y position, or `nullptr`.

Returns: A #cairo_surface_t representing cursor, or nullptr.

◆ get_surface() [2/2]

::Cairo::RefPtr<const ::Cairo::Surface> Gdk::Cursor::get_surface	(	double &	x_hot,
		double &	y_hot
	)		const

Returns a cairo image surface 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, nullptr is returned.

Since gtkmm 3.10:

Parameters

x_hot	Location to store the hotspot x position, or `nullptr`.
y_hot	Location to store the hotspot y position, or `nullptr`.

Returns: A #cairo_surface_t representing cursor, or nullptr.

◆ get_type()

static GType Gdk::Cursor::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.
