Struct zng_wgt_text :: FontMix Copy item path

impl FontMix<()>

pub fn context_vars_set(set: &mut ContextValueSet)

Insert context variables used by properties in this mix-in.

impl<P: WidgetImpl> FontMix

pub fn font_family(&self, names: impl IntoVar<FontNames>)

P Font family name or list of names for texts in this widget or descendants.

All fonts in the list are resolved according to the font_style, font_weight and font_stretch config. During text shaping the first font on the list is preferred, but if the font does not cover a character or word, that character or word to the second font in the list and so on.

Sets the FONT_FAMILY_VAR.

impl<P: WidgetImpl> FontMix

pub fn font_size(&self, size: impl IntoVar<FontSize>)

P Sets the font size for the widget and descendants.

This property affects all texts inside the widget and the Length::Em unit.

Sets the FONT_SIZE_VAR context var and the LayoutMetrics::font_size.

impl<P: WidgetImpl> FontMix

pub fn font_weight(&self, weight: impl IntoVar<FontWeight>)

P Defines the thickness or boldness the preferred font should have.

This value influences font resolution, the variant within the font family that is closest to this config will be selected.

Sets the FONT_WEIGHT_VAR.

impl<P: WidgetImpl> FontMix

pub fn font_style(&self, style: impl IntoVar<FontStyle>)

P Defines the skew style of the font glyphs.

This value influences font resolution, the variant within the font family that is closest to this config will be selected.

Sets the FONT_STYLE_VAR.

impl<P: WidgetImpl> FontMix

pub fn font_stretch(&self, stretch: impl IntoVar<FontStretch>)

P Defines how condensed or expanded the preferred font should be.

This value influences font resolution, the variant within the font family that is closest to this config will be selected.

Sets the FONT_STRETCH_VAR.

impl<P: WidgetImpl> FontMix

pub fn font_synthesis(&self, enabled: impl IntoVar<FontSynthesis>)

P Configure if a synthetic font is generated for fonts that do not implement bold or oblique variants.

Not all fonts implement the requested font_weight and font_style, this config allows the renderer to try and generate the style and weight anyway, using transforms and the glyph outlines.

Sets the FONT_SYNTHESIS_VAR.

impl<P: WidgetImpl> FontMix

pub fn font_aa(&self, aa: impl IntoVar<FontAntiAliasing>)

P Configure the anti-aliasing used to render text glyphs inside the widget.

Uses the operating system configuration by default.

Sets the FONT_AA_VAR.
