Methods

impl CGDisplay

fn new(id: CGDirectDisplayID) -> CGDisplay

fn main() -> CGDisplay

Returns the the main display.

fn bounds(&self) -> CGRect

Returns the bounds of a display in the global display coordinate space.

fn display_mode(&self) -> Option<CGDisplayMode>

Returns information about a display's current configuration.

fn image(&self) -> Option<CGImage>

Returns an image containing the contents of the specified display.

fn screenshot(
    bounds: CGRect,
    list_option: CGWindowListOption,
    window_id: CGWindowID,
    image_option: CGWindowImageOption
) -> Option<CGImage>

Returns a composite image based on a dynamically generated list of windows.

fn screenshot_from_windows(

    windows: CFArray,
    image_option: CGWindowImageOption
) -> Option<CGImage>

Returns a composite image of the specified windows.

fn window_list_info(
    option: CGWindowListOption,
    relative_to_window: Option<CGWindowID>
) -> Option<CFArray>

Generates and returns information about the selected windows in the current user session.

fn is_active(&self) -> bool

Returns a Boolean value indicating whether a display is active.

fn is_always_in_mirror_set(&self) -> bool

Returns a boolean indicating whether a display is always in a mirroring set.

fn is_asleep(&self) -> bool

Returns a boolean indicating whether a display is sleeping (and is therefore not drawable.)

fn is_builtin(&self) -> bool

Returns a boolean indicating whether a display is built-in, such as the internal display in portable systems.

fn is_in_hw_mirror_set(&self) -> bool

Returns a boolean indicating whether a display is in a hardware mirroring set.

fn is_in_mirror_set(&self) -> bool

Returns a boolean indicating whether a display is in a mirroring set.

fn is_main(&self) -> bool

Returns a boolean indicating whether a display is the main display.

fn is_online(&self) -> bool

Returns a boolean indicating whether a display is connected or online.

fn uses_open_gl_acceleration(&self) -> bool

Returns a boolean indicating whether Quartz is using OpenGL-based window acceleration (Quartz Extreme) to render in a display.

fn is_stereo(&self) -> bool

Returns a boolean indicating whether a display is running in a stereo graphics mode.

fn mirrors_display(&self) -> CGDirectDisplayID

For a secondary display in a mirroring set, returns the primary display.

fn primary_display(&self) -> CGDirectDisplayID

Returns the primary display in a hardware mirroring set.

fn rotation(&self) -> f64

Returns the rotation angle of a display in degrees.

fn screen_size(&self) -> CGSize

Returns the width and height of a display in millimeters.

fn serial_number(&self) -> u32

Returns the serial number of a display monitor.

fn unit_number(&self) -> u32

Returns the logical unit number of a display.

fn vendor_number(&self) -> u32

Returns the vendor number of the specified display's monitor.

fn model_number(&self) -> u32

Returns the model number of a display monitor.

fn pixels_high(&self) -> u64

Returns the display height in pixel units.

fn pixels_wide(&self) -> u64

Returns the display width in pixel units.

fn active_displays() -> Result<Vec<CGDirectDisplayID>, CGError>

Provides a list of displays that are active (or drawable).

fn active_display_count() -> Result<u32, CGError>

Provides count of displays that are active (or drawable).

fn hide_cursor(&self) -> Result<(), CGError>

Hides the mouse cursor, and increments the hide cursor count.

fn show_cursor(&self) -> Result<(), CGError>

Decrements the hide cursor count, and shows the mouse cursor if the count is 0.

fn move_cursor_to_point(&self, point: CGPoint) -> Result<(), CGError>

Moves the mouse cursor to a specified point relative to the display origin (the upper-left corner of the display).

fn warp_mouse_cursor_position(point: CGPoint) -> Result<(), CGError>

Moves the mouse cursor without generating events.

fn associate_mouse_and_mouse_cursor_position(
    connected: bool
) -> Result<(), CGError>

Connects or disconnects the mouse and cursor while an application is in the foreground.
