Methods
impl WlOutput
[src]
fn geometry(&self, x: i32, y: i32, physical_width: i32, physical_height: i32, subpixel: Subpixel, make: String, model: String, transform: Transform) -> EventResult<()>
properties of the output
The geometry event describes geometric properties of the output. The event is sent when binding to the output object and whenever any of the properties change.
fn mode(&self, flags: Mode, width: i32, height: i32, refresh: i32) -> EventResult<()>
advertise available modes for the output
The mode event describes an available mode for the output.
The event is sent when binding to the output object and there will always be one mode, the current mode. The event is sent again if an output changes mode, for the mode that is now current. In other words, the current mode is always the last mode that was received with the current flag set.
The size of a mode is given in physical hardware units of the output device. This is not necessarily the same as the output size in the global compositor space. For instance, the output may be scaled, as described in wl_output.scale, or transformed, as described in wl_output.transform.
fn done(&self) -> EventResult<()>
sent all information about output
This event is sent after all other properties have been sent after binding to the output object and after any other property changes done after that. This allows changes to the output properties to be seen as atomic, even if they happen via multiple events.
fn scale(&self, factor: i32) -> EventResult<()>
output scaling properties
This event contains scaling geometry information that is not in the geometry event. It may be sent after binding the output object or if the output scale changes later. If it is not sent, the client should assume a scale of 1.
A scale larger than 1 means that the compositor will automatically scale surface buffers by this amount when rendering. This is used for very high resolution displays where applications rendering at the native resolution would be too small to be legible.
It is intended that scaling aware clients track the current output of a surface, and if it is on a scaled output it should use wl_surface.set_buffer_scale with the scale of the output. That way the compositor can avoid scaling the surface, and the client can supply a higher detail image.
