Expand description

Trait containing all Monitor methods.

Implementors

Monitor

Required methods

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

Returns

the name of the connector

Gets the display that this monitor belongs to.

Returns

the display

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

Gets the height in millimeters of the monitor.

Returns

the physical height of the monitor

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

Gets the string identifying the monitor model, if available.

Returns

the monitor model

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

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

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

Returns

the subpixel layout

Gets the width in millimeters of the monitor.

Returns

the physical width of the monitor

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

Emitted when the output represented by monitor gets disconnected.
