Implementations

impl ScreenResources

pub fn new(handle: &mut XHandle) -> Result<ScreenResources, XrandrError>

Create a handle to the XRRScreenResources object from libxrandr. This handle is used to query many parts of the current x11 config.

Errors

• XrandrError::GetResources - Getting the handle failed.

Examples

let xhandle = XHandle.open()?;
let res = ScreenResources::new(&mut xhandle)?;
let crtc_87 = res.crtc(&mut xhandle, 87);

pub fn outputs(&self, handle: &mut XHandle) -> Result<Vec<Output>, XrandrError>

Gets information on all outputs

Errors

• XrandrError::GetOutputInfo(xid) – Getting info failed for output xid

Examples

let res = ScreenResources::new(&mut xhandle)?;
let outputs = res.outputs(&mut xhandle);

pub fn output( &self, handle: &mut XHandle, xid: XId, ) -> Result<Output, XrandrError>

Gets information on output with given xid

Errors

• XrandrError::GetOutputInfo(xid) – Getting info failed for output with XID xid

Examples

let res = ScreenResources::new(&mut xhandle)?;
let output_89 = res.output(&mut xhandle, 89);

pub fn crtcs(&self, handle: &mut XHandle) -> Result<Vec<Crtc>, XrandrError>

Gets information on all crtcs

Errors

• XrandrError::GetCrtcInfo(xid) – Getting info failed for crtc with XID xid

Examples

let res = ScreenResources::new(&mut xhandle)?;
let crtcs = res.crtcs(&mut xhandle);

pub fn enabled_crtcs( &self, handle: &mut XHandle, ) -> Result<Vec<Crtc>, XrandrError>

Gets information of only the enabled crtcs See also: self.crtcs()

Errors

• XrandrError::GetCrtcInfo(xid) – Getting info failed for crtc with XID xid

pub fn crtc(&self, handle: &mut XHandle, xid: XId) -> Result<Crtc, XrandrError>

Gets information on crtc with given xid

Errors

• XrandrError::GetCrtcInfo(xid) – Getting info failed for crtc with XID xid

Examples

let res = ScreenResources::new(&mut xhandle)?;
let current_crtc = res.crtc(&mut xhandle, output.crtc);

pub fn modes(&self) -> Vec<Mode>

Gets information on all crtcs

Errors

• XrandrError::GetCrtcInfo(xid) – Getting info failed for crtc with XID xid

Examples

let res = ScreenResources::new(&mut xhandle)?;
let crtcs = res.crtcs(&mut xhandle);

pub fn mode(&self, xid: XId) -> Result<Mode, XrandrError>

Gets information on mode with given xid

Errors

• XrandrError::GetModeInfo(xid) – Getting info failed for mode with XID xid

Examples

let res = ScreenResources::new(&mut xhandle)?;
let current_mode = res.mode(&mut xhandle, output.mode);
