pub struct Cursor { /* private fields */ }
Expand description

A Cursor represents a cursor. Its contents are private.

This is an Abstract Base Class, you cannot instantiate it.

Implementations

Creates a new cursor from the set of builtin cursors.

display

the Display for which the cursor will be created

cursor_type

cursor to create

Returns

a new Cursor, or None on failure

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”
display

the Display for which the cursor will be created

name

the name of the cursor

Returns

a new Cursor, or None if there is no cursor with the given name

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 Display::supports_cursor_alpha() and Display::supports_cursor_color() can be used to determine whether RGBA cursors are supported; Display::default_cursor_size() and Display::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 Display for which the cursor will be created

pixbuf

the gdk_pixbuf::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 Cursor.

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 Display::supports_cursor_alpha() and Display::supports_cursor_color() can be used to determine whether RGBA cursors are supported; Display::default_cursor_size() and Display::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.

display

the 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 Cursor.

Returns the cursor type for this cursor.

Returns

a CursorType

Returns the display on which the Cursor is defined.

Returns

the Display associated to self

Returns a gdk_pixbuf::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, None is returned.

Returns

a gdk_pixbuf::Pixbuf representing self, or None

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, None is returned.

Returns

a cairo::Surface representing self, or None

x_hot

Location to store the hotspot x position, or None

y_hot

Location to store the hotspot y position, or None
