Struct PrintOperationPreview

pub struct PrintOperationPreview { /* private fields */ }

PrintOperationPreview is the interface that is used to implement print preview.

A PrintOperationPreview object is passed to the preview signal by PrintOperation.

Signals

got-page-size

Emitted once for each page that gets rendered to the preview.

A handler for this signal should update the @context according to @page_setup and set up a suitable cairo context, using PrintContext::set_cairo_context().

ready

The ::ready signal gets emitted once per preview operation, before the first page is rendered.

A handler for this signal can be used for setup tasks.

Implements

PrintOperationPreviewExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl PrintOperationPreview

pub const NONE: Option<&'static PrintOperationPreview> = None

Trait Implementations

impl Clone for PrintOperationPreview

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for PrintOperationPreview

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

Formats the value using the given formatter.

impl HasParamSpec for PrintOperationPreview

type ParamSpec = ParamSpecObject

type SetValue = PrintOperationPreview

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, PrintOperationPreview>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for PrintOperationPreview

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: PrintOperationPreviewImpl> IsImplementable<T> for PrintOperationPreview

fn interface_init(iface: &mut Interface<Self>)

Override the virtual methods of this interface for the given subclass and do other interface initialization.

fn instance_init(_instance: &mut InitializingObject<T>)

Instance specific initialization.

impl Ord for PrintOperationPreview

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<OT: ObjectType> PartialEq<OT> for PrintOperationPreview

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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

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

impl<OT: ObjectType> PartialOrd<OT> for PrintOperationPreview

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for PrintOperationPreview

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for PrintOperationPreview
