Enum Event

pub enum Event {
    Scale {
        flags: Enum<ScaleProperty>,
        scale: Enum<ScaleFactor>,
    },
    Connection {
        connection: Enum<ConnectionType>,
    },
    DeviceScaleFactor {
        scale: Enum<ScaleFactor>,
    },
}

Variants

Scale

advertise available scales for the output

The scale event describes an available scale for the output.

The event is sent when binding to the output object and there will always be one scale, the current scale. The event is sent again if an output changes scale, for the scale that is now current. In other words, the current scale is always the last scale that was received with the current flag set.

Fields

flags: Enum<ScaleProperty>

bitfield of scale flags

scale: Enum<ScaleFactor>

output scale

Connection

advertise connection for the output

The connection event describes how the output is connected.

The event is sent when binding to the output object.

Fields

connection: Enum<ConnectionType>

output connection

DeviceScaleFactor

advertise device scale factor for the output

This event describes the device specific scale factor for the output.

The device specific scale factor is not expected the change during the lifetime of the output. And it is not limited to an integer value like the scale factor provided by wl_output interface. The exact contents scale used by the compositor can be determined by combining this device scale factor with the current output scale.

The event is sent when binding to the output object.

Fields

scale: Enum<ScaleFactor>

output device scale factor
