Struct i_slint_core::graphics::FontRequest

pub struct FontRequest {
    pub family: Option<SharedString>,
    pub weight: Option<i32>,
    pub pixel_size: Option<LogicalLength>,
    pub letter_spacing: Option<LogicalLength>,
}

FontRequest collects all the developer-configurable properties for fonts, such as family, weight, etc. It is submitted as a request to the platform font system (i.e. CoreText on macOS) and in exchange the backend returns a Box<dyn Font>.

Fields

family: Option<SharedString>

The name of the font family to be used, such as “Helvetica”. An empty family name means the system default font family should be used.

weight: Option<i32>

If the weight is None, the system default font weight should be used.

pixel_size: Option<LogicalLength>

If the pixel size is None, the system default font size should be used.

letter_spacing: Option<LogicalLength>

The additional spacing (or shrinking if negative) between glyphs. This is usually not submitted to the font-subsystem but collected here for API convenience

Trait Implementations

impl Clone for FontRequest

fn clone(&self) -> FontRequest

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FontRequest

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FontRequest

fn default() -> FontRequest

Returns the “default value” for a type.

impl PartialEq<FontRequest> for FontRequest

fn eq(&self, other: &FontRequest) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
