Struct gsk4::BorderNode
source · pub struct BorderNode { /* private fields */ }
Expand description
A render node for a border.
GLib type: Shared boxed type with reference counted clone semantics.
Implementations§
source§impl BorderNode
impl BorderNode
sourcepub fn as_ptr(&self) -> *mut GskBorderNode
pub fn as_ptr(&self) -> *mut GskBorderNode
Return the inner pointer to the underlying C value.
sourcepub unsafe fn from_glib_ptr_borrow(ptr: &*mut GskBorderNode) -> &Self
pub unsafe fn from_glib_ptr_borrow(ptr: &*mut GskBorderNode) -> &Self
Borrows the underlying C value.

sourcepub fn outline(&self) -> RoundedRect
pub fn outline(&self) -> RoundedRect
source§impl BorderNode
impl BorderNode
sourcepub fn new(
outline: &RoundedRect,
border_width: &[f32; 4],
border_color: &[RGBA; 4],
) -> Self
pub fn new( outline: &RoundedRect, border_width: &[f32; 4], border_color: &[RGBA; 4], ) -> Self
Creates a RenderNode
that will stroke a border rectangle inside the
given @outline.
The 4 sides of the border can have different widths and colors.
§outline
a RoundedRect
describing the outline of the border
§border_width
the stroke width of the border on the top, right, bottom and left side respectively.
§border_color
the color used on the top, right, bottom and left side.
§Returns
A new RenderNode
Methods from Deref<Target = RenderNode>§
sourcepub fn as_ptr(&self) -> *mut GskRenderNode
pub fn as_ptr(&self) -> *mut GskRenderNode
Return the inner pointer to the underlying C value.
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 opaque_rect(&self) -> Option<Rect>
Available on crate feature v4_16
only.
pub fn opaque_rect(&self) -> Option<Rect>
v4_16
only.Gets an opaque rectangle inside the node that GTK can determine to be fully opaque.
There is no guarantee that this is indeed the largest opaque rectangle or that regions outside the rectangle are not opaque. This function is a best effort with that goal.
The rectangle will be fully contained in the bounds of the node.
§Returns
true
if part or all of the rendernode is opaque, false
if no
opaque region could be found.
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
