Struct RichText 

#[non_exhaustive]
pub struct RichText {
    pub root_id: WidgetId,
    pub caret: RichCaretInfo,
    /* private fields */
}

Represents the rich text context.

Use TEXT to get.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

root_id: WidgetId

Widget that defines the rich text context.

caret: RichCaretInfo

Widgets that define the caret and selection indexes.

Implementations

impl RichText

pub fn root_info(&self) -> Option<WidgetInfo>

Get root widget info.

pub fn leaves(&self) -> impl Iterator<Item = WidgetInfo> + 'static

Iterate over the text/leaf component descendants that can be interacted with.

pub fn leaves_rev(&self) -> impl Iterator<Item = WidgetInfo> + 'static

Iterate over the text/leaf component descendants that can be interacted with in reverse.

pub fn selection(&self) -> impl ExactSizeIterator<Item = WidgetInfo> + 'static

Iterate over all text/leaf components that are part of the selection.

The return iterator is empty if there is no selection.

pub fn selection_rev( &self, ) -> impl ExactSizeIterator<Item = WidgetInfo> + 'static

Iterate over all text/leaf components that are part of the selection in reverse.

The return iterator is empty if there is no selection.

pub fn caret_index_info(&self) -> Option<WidgetInfo>

Gets the caret.index widget info if it is set and is a valid leaf.

pub fn caret_selection_index_info(&self) -> Option<WidgetInfo>

Gets the caret.selection_index widget info if it is set and is a valid leaf.

pub fn leaf_info(&self, id: WidgetId) -> Option<WidgetInfo>

Gets the id widget info if it is a valid leaf in the rich text context.
