Struct druid::widget::Align

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

A widget that aligns its child.

Implementations

impl<T> Align<T>

pub fn new(align: UnitPoint, child: impl Widget<T> + 'static) -> Align<T>

Create widget with alignment.

Note that the align parameter is specified as a UnitPoint in terms of left and right. This is inadequate for bidi-aware layout and thus the API will change when druid gains bidi capability.

pub fn centered(child: impl Widget<T> + 'static) -> Align<T>

Create centered widget.

pub fn right(child: impl Widget<T> + 'static) -> Align<T>

Create right-aligned widget.

pub fn left(child: impl Widget<T> + 'static) -> Align<T>

Create left-aligned widget.

pub fn horizontal(align: UnitPoint, child: impl Widget<T> + 'static) -> Align<T>

Align only in the horizontal axis, keeping the child's size in the vertical.

pub fn vertical(align: UnitPoint, child: impl Widget<T> + 'static) -> Align<T>

Align only in the vertical axis, keeping the child's size in the horizontal.
