Struct ShapeBorderClipper 

pub struct ShapeBorderClipper {
    pub shape: Box<dyn ShapeBorder>,
    pub text_direction: Option<TextDirection>,
}

A CustomClipper that clips to the outer path of a ShapeBorder.

Fields

shape: Box<dyn ShapeBorder>

The shape border whose outer path defines the clip.

text_direction: Option<TextDirection>

The text direction to use for getting the outer path for shape.

ShapeBorders can depend on the text direction (e.g having a “dent” on the left hand side in LTR and on the right hand side in RTL).

Implementations

impl ShapeBorderClipper

pub fn new( shape: Box<dyn ShapeBorder>, text_direction: Option<TextDirection>, ) -> Self

Creates a ShapeBorder clipper.

The text_direction argument must be provided non-None if shape has a text direction dependency (for example if it is expressed in terms of “start” and “end” instead of “left” and “right”). It may be None if the border will not need the text direction to paint itself.

Trait Implementations

impl CustomClipper<Arc<Path>> for ShapeBorderClipper

fn get_clip(&self, size: Size) -> Arc<Path>

Returns a description of the clip given that the render object being clipped is of the given size.

fn should_reclip(&self, old_clipper: &dyn CustomClipper<Arc<Path>>) -> bool

Called whenever a new instance of the custom clipper delegate class is provided to the clip object, or any time that a new clip object is created with a new instance of the custom clipper delegate class (which amounts to the same thing, because the latter is implemented in terms of the former).

fn as_any(&self) -> &dyn Any

Downcast support for Dart’s runtimeType comparison and covariant parameter.

fn reclip(&self) -> Option<&Rc<dyn Listenable>>

The Listenable that notifies when it is time to reclip.
