Struct druid::widget::RawLabel

pub struct RawLabel<T> { /* fields omitted */ }

A widget that displays text data.

This requires the Data to be ArcStr; to handle static, dynamic, or localized text, use Label.

Implementations

impl<T: TextStorage> RawLabel<T>

pub fn new() -> Self

Create a new RawLabel.

pub fn with_text_color(self, color: impl Into<KeyOrValue<Color>>) -> Self

Builder-style method for setting the text color.

The argument can be either a Color or a Key<Color>.

pub fn with_text_size(self, size: impl Into<KeyOrValue<f64>>) -> Self

Builder-style method for setting the text size.

The argument can be either an f64 or a Key<f64>.

pub fn with_font(self, font: impl Into<KeyOrValue<FontDescriptor>>) -> Self

Builder-style method for setting the font.

The argument can be a FontDescriptor or a Key<FontDescriptor> that refers to a font defined in the Env.

pub fn with_line_break_mode(self, mode: LineBreaking) -> Self

Builder-style method to set the LineBreaking behaviour.

pub fn with_text_alignment(self, alignment: TextAlignment) -> Self

Builder-style method to set the TextAlignment.

pub fn set_text_color(&mut self, color: impl Into<KeyOrValue<Color>>)

Set the text color.

The argument can be either a Color or a Key<Color>.

If you change this property, you are responsible for calling request_layout to ensure the label is updated.

pub fn set_text_size(&mut self, size: impl Into<KeyOrValue<f64>>)

Set the text size.

The argument can be either an f64 or a Key<f64>.

If you change this property, you are responsible for calling request_layout to ensure the label is updated.

pub fn set_font(&mut self, font: impl Into<KeyOrValue<FontDescriptor>>)

Set the font.

The argument can be a FontDescriptor or a Key<FontDescriptor> that refers to a font defined in the Env.

If you change this property, you are responsible for calling request_layout to ensure the label is updated.

pub fn set_line_break_mode(&mut self, mode: LineBreaking)

Set the LineBreaking behaviour.

If you change this property, you are responsible for calling request_layout to ensure the label is updated.

pub fn set_text_alignment(&mut self, alignment: TextAlignment)

Set the TextAlignment for this layout.

pub fn draw_at(&self, ctx: &mut PaintCtx<'_, '_, '_>, origin: impl Into<Point>)

Draw this label's text at the provided Point, without internal padding.

This is a convenience for widgets that want to use Label as a way of managing a dynamic or localized string, but want finer control over where the text is drawn.

pub fn baseline_offset(&self) -> f64

Return the offset of the first baseline relative to the bottom of the widget.

Trait Implementations

impl<T: TextStorage> Default for RawLabel<T>

pub fn default() -> Self

Returns the "default value" for a type.

impl<T: TextStorage> Widget<T> for RawLabel<T>

    &mut self,
    _ctx: &mut EventCtx<'_, '_>,
    _event: &Event,
    _data: &mut T,

)

pub fn lifecycle(
    &mut self,
    _ctx: &mut LifeCycleCtx<'_, '_>,
    event: &LifeCycle,
    data: &T,
    _env: &Env
)

Handle a life cycle notification.

pub fn update(
    &mut self,
    ctx: &mut UpdateCtx<'_, '_>,
    old_data: &T,
    data: &T,
    _env: &Env
)

Update the widget's appearance in response to a change in the app's Data or Env.

    env: &Env
) -> Size

Compute layout.

pub fn paint(&mut self, ctx: &mut PaintCtx<'_, '_, '_>, _data: &T, _env: &Env)

Paint the widget appearance.
