Expand description

A render node for an inset shadow.

Implementations§

source§

impl InsetShadowNode

source

pub fn as_ptr(&self) -> *mut GskInsetShadowNode

Return the inner pointer to the underlying C value.

source

pub unsafe fn from_glib_ptr_borrow<'a>( ptr: *const *const GskInsetShadowNode ) -> &'a Self

Borrows the underlying C value.

source§

impl InsetShadowNode

source

pub fn new( outline: &RoundedRect, color: &RGBA, dx: f32, dy: f32, spread: f32, blur_radius: f32 ) -> InsetShadowNode

Creates a RenderNode that will render an inset shadow into the box given by @outline.

§outline

outline of the region containing the shadow

§color

color of the shadow

§dx

horizontal offset of shadow

§dy

vertical offset of shadow

§spread

how far the shadow spreads towards the inside

§blur_radius

how much blur to apply to the shadow

§Returns

A new RenderNode

source

pub fn blur_radius(&self) -> f32

Retrieves the blur radius to apply to the shadow.

§Returns

the blur radius, in pixels

source

pub fn color(&self) -> RGBA

Retrieves the color of the inset shadow.

§Returns

the color of the shadow

source

pub fn dx(&self) -> f32

Retrieves the horizontal offset of the inset shadow.

§Returns

an offset, in pixels

source

pub fn dy(&self) -> f32

Retrieves the vertical offset of the inset shadow.

§Returns

an offset, in pixels

source

pub fn outline(&self) -> RoundedRect

Retrieves the outline rectangle of the inset shadow.

§Returns

a rounded rectangle

source

pub fn spread(&self) -> f32

Retrieves how much the shadow spreads inwards.

§Returns

the size of the shadow, in pixels

Methods from Deref<Target = RenderNode>§

source

pub fn as_ptr(&self) -> *mut GskRenderNode

Return the inner pointer to the underlying C value.

source

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

source

pub fn draw(&self, cr: &Context)

Draw the contents of @self to the given cairo context.

Typically, you’ll use this function to implement fallback rendering of RenderNodes on an intermediate Cairo context, instead of using the drawing context associated to a gdk::Surface’s rendering buffer.

For advanced nodes that cannot be supported using Cairo, in particular for nodes doing 3D operations, this function may fail.

§cr

cairo context to draw to

source

pub fn bounds(&self) -> Rect

Retrieves the boundaries of the @self.

The node will not draw outside of its boundaries.

§Returns
§bounds

return location for the boundaries

source

pub fn node_type(&self) -> RenderNodeType

Returns the type of the @self.

§Returns

the type of the RenderNode

source

pub fn serialize(&self) -> Bytes

Serializes the @self for later deserialization via gsk_render_node_deserialize(). No guarantees are made about the format used other than that the same version of GTK will be able to deserialize the result of a call to gsk_render_node_serialize() and gsk_render_node_deserialize() will correctly reject files it cannot open that were created with previous versions of GTK.

The intended use of this functions is testing, benchmarking and debugging. The format is not meant as a permanent storage format.

§Returns

a GBytes representing the node.

source

pub fn write_to_file(&self, filename: impl AsRef<Path>) -> Result<(), Error>

This function is equivalent to calling serialize() followed by file_set_contents().

See those two functions for details on the arguments.

It is mostly intended for use inside a debugger to quickly dump a render node to a file for later inspection.

§filename

the file to save it to.

§Returns

true if saving was successful

source

pub fn is<T: IsRenderNode>(&self) -> bool

source

pub fn type_(&self) -> Type

source

pub fn downcast_ref<T: IsRenderNode>(&self) -> Option<&T>
