[−][src]Struct druid::widget::List
A list widget for a variable-size collection of items.
Implementations
impl<T: Data> List<T>
[src]
pub fn new<W: Widget<T> + 'static>(closure: impl Fn() -> W + 'static) -> Self
[src]
Create a new list widget. Closure will be called every time when a new child needs to be constructed.
pub fn horizontal(self) -> Self
[src]
Sets the widget to display the list horizontally, not vertically.
pub fn with_spacing(self, spacing: impl Into<KeyOrValue<f64>>) -> Self
[src]
Set the spacing between elements.
pub fn set_spacing(&mut self, spacing: impl Into<KeyOrValue<f64>>) -> &mut Self
[src]
Set the spacing between elements.
