Expand description
A render node for an inset shadow.
Implementations§
source§impl InsetShadowNode
impl InsetShadowNode
sourcepub fn new(
outline: &RoundedRect,
color: &RGBA,
dx: f32,
dy: f32,
spread: f32,
blur_radius: f32
) -> InsetShadowNode
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
sourcepub fn blur_radius(&self) -> f32
pub fn blur_radius(&self) -> f32

pub fn outline(&self) -> RoundedRect
Methods from Deref<Target = RenderNode>§
pub const NONE: Option<&'static RenderNode> = None
sourcepub fn draw(&self, cr: &Context)
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 RenderNode
s 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
sourcepub fn node_type(&self) -> RenderNodeType
pub fn node_type(&self) -> RenderNodeType
sourcepub fn serialize(&self) -> Bytes
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.
sourcepub fn write_to_file(&self, filename: impl AsRef<Path>) -> Result<(), Error>
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
