Trait containing all Monitor methods.

Implementors

Monitor

Required Methods§

source

fn connector(&self) -> Option<GString>

Gets the name of the monitor’s connector, if available.

These are strings such as “eDP-1”, or “HDMI-2”. They depend on software and hardware configuration, and should not be relied on as stable identifiers of a specific monitor.

Returns

the name of the connector

source

fn description(&self) -> Option<GString>

Available on crate feature v4_10 only.

Gets a string describing the monitor, if available.

This can be used to identify a monitor in the UI.

Returns

the monitor description

source

fn display(&self) -> Display

Gets the display that this monitor belongs to.

Returns

the display

source

fn geometry(&self) -> Rectangle

Retrieves the size and position of the monitor within the display coordinate space.

The returned geometry is in ”application pixels”, not in ”device pixels” (see scale_factor()).

Returns
geometry

a Rectangle to be filled with the monitor geometry

source

fn height_mm(&self) -> i32

Gets the height in millimeters of the monitor.

Returns

the physical height of the monitor

source

fn manufacturer(&self) -> Option<GString>

Gets the name or PNP ID of the monitor’s manufacturer.

Note that this value might also vary depending on actual display backend.

The PNP ID registry is located at https://uefi.org/pnp_id_list.

Returns

the name of the manufacturer

source

fn model(&self) -> Option<GString>

Gets the string identifying the monitor model, if available.

Returns

the monitor model

source

fn refresh_rate(&self) -> i32

Gets the refresh rate of the monitor, if available.

The value is in milli-Hertz, so a refresh rate of 60Hz is returned as 60000.

Returns

the refresh rate in milli-Hertz, or 0

source

fn scale_factor(&self) -> i32

Gets the internal scale factor that maps from monitor coordinates to device pixels.

On traditional systems this is 1, but on very high density outputs it can be a higher value (often 2).

This can be used if you want to create pixel based data for a particular monitor, but most of the time you’re drawing to a surface where it is better to use SurfaceExt::scale_factor() instead.

Returns

the scale factor

source

fn subpixel_layout(&self) -> SubpixelLayout

Gets information about the layout of red, green and blue primaries for pixels.

Returns

the subpixel layout

source

fn width_mm(&self) -> i32

Gets the width in millimeters of the monitor.

Returns

the physical width of the monitor

source

fn is_valid(&self) -> bool

Returns true if the @self object corresponds to a physical monitor.

The @self becomes invalid when the physical monitor is unplugged or removed.

Returns

true if the object corresponds to a physical monitor

source

fn connect_invalidate<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

Emitted when the output represented by @monitor gets disconnected.

source

fn connect_connector_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

source

fn connect_description_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

Available on crate feature v4_10 only.
source

fn connect_geometry_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

source

fn connect_height_mm_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

source

fn connect_manufacturer_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

source

fn connect_model_notify<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

source

fn connect_refresh_rate_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

source

fn connect_scale_factor_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

source

fn connect_subpixel_layout_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

source

fn connect_valid_notify<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

source

fn connect_width_mm_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId
