Struct zng_ext_window::HeadlessMonitor

pub struct HeadlessMonitor {
    pub scale_factor: Option<Factor>,
    pub size: DipSize,
    pub ppi: Ppi,
}

“Monitor” configuration used by windows in headless mode.

Fields

scale_factor: Option<Factor>

The scale factor used for the headless layout and rendering.

If set to None, falls back to the parent scale-factor, or 1.0 if the headless window has not parent.

None by default.

size: DipSize

Size of the imaginary monitor screen that contains the headless window.

This is used to calculate relative lengths in the window size definition and is defined in layout pixels instead of device like in a real monitor info.

(11608, 8708) by default.

ppi: Ppi

Pixel-per-inches used for the headless layout and rendering.

Implementations

impl HeadlessMonitor

pub fn new(size: DipSize) -> Self

New with custom size at None scale.

pub fn new_scaled(size: DipSize, scale_factor: Factor) -> Self

New with custom size and scale.

pub fn new_scale(scale_factor: Factor) -> Self

New with default size (11608, 8708) and custom scale.

Trait Implementations

impl Clone for HeadlessMonitor

fn clone(&self) -> HeadlessMonitor

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HeadlessMonitor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for HeadlessMonitor

fn default() -> Self

New (11608, 8708) at None scale.

impl<W: Into<Dip>, H: Into<Dip>> From<(W, H)> for HeadlessMonitor

fn from((width, height): (W, H)) -> Self

Converts to this type from the input type.

impl<W: Into<Dip>, H: Into<Dip>, F: Into<Factor>> From<(W, H, F)> for HeadlessMonitor

fn from((width, height, scale): (W, H, F)) -> Self

Converts to this type from the input type.

impl<W: Into<Dip>, H: Into<Dip>> IntoVar<HeadlessMonitor> for (W, H)

type Var = LocalVar<HeadlessMonitor>

Variable type that will wrap the T value.

fn into_var(self) -> Self::Var

Converts the source value into a var.

fn into_boxed_var(self) -> Box<dyn VarBoxed<T>>

where Self: Sized,

Converts into BoxedVar<T>.

impl<W: Into<Dip>, H: Into<Dip>, F: Into<Factor>> IntoVar<HeadlessMonitor> for (W, H, F)

type Var = LocalVar<HeadlessMonitor>

Variable type that will wrap the T value.

fn into_var(self) -> Self::Var

Converts the source value into a var.

fn into_boxed_var(self) -> Box<dyn VarBoxed<T>>

where Self: Sized,

Converts into BoxedVar<T>.

impl PartialEq for HeadlessMonitor

fn eq(&self, other: &HeadlessMonitor) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for HeadlessMonitor

impl<W: Into<Dip>, H: Into<Dip>> IntoValue<HeadlessMonitor> for (W, H)

impl<W: Into<Dip>, H: Into<Dip>, F: Into<Factor>> IntoValue<HeadlessMonitor> for (W, H, F)
