Struct SelectionRegion 

pub struct SelectionRegion {
    pub id: Option<WidgetId>,
    pub child: Widget,
    pub separator: String,
    pub controls: SelectionRegionControls,
    pub excluded: bool,
}

Coordinates read-only selection across all selectable text descendants.

A Text or RichText with selectable(true) remains independently selectable when no explicit region surrounds it. Wrap several such widgets in a SelectionRegion to make dragging, copying, and select-all operate on their retained document order as one selection.

Fields

id: Option<WidgetId>

child: Widget

separator: String

Text inserted between descendants when copying the coordinated value.

controls: SelectionRegionControls

excluded: bool

An excluded region blocks selection inherited from an ancestor region.

Implementations

impl SelectionRegion

pub fn new(child: impl Into<Widget>) -> Self

pub fn exclude(child: impl Into<Widget>) -> Self

Excludes an otherwise selectable subtree from its nearest ancestor region.

pub fn controller(self, controller: SelectionRegionController) -> Self

pub fn separator(self, separator: impl Into<String>) -> Self

pub fn controls(self, controls: SelectionRegionControls) -> Self
