Required Associated Constants§
sourceconst CHECKMARK_ICON: char
const CHECKMARK_ICON: char

Required Methods§
sourcefn default_size(&self) -> f32
fn default_size(&self) -> f32
Returns the default size of Text
.
sourcefn measure(
&self,
content: &str,
size: f32,
font: Self::Font,
bounds: Size
) -> (f32, f32)
fn measure( &self, content: &str, size: f32, font: Self::Font, bounds: Size ) -> (f32, f32)
Measures the text in the given bounds and returns the minimum boundaries that can fit the contents.
sourcefn hit_test(
&self,
contents: &str,
size: f32,
font: Self::Font,
bounds: Size,
point: Point,
nearest_only: bool
) -> Option<Hit>
fn hit_test( &self, contents: &str, size: f32, font: Self::Font, bounds: Size, point: Point, nearest_only: bool ) -> Option<Hit>
Tests whether the provided point is within the boundaries of text laid out with the given parameters, returning information about the nearest character.
If nearest_only
is true, the hit test does not consider whether the
the point is interior to any glyph bounds, returning only the character
with the nearest centeroid.
