}

Extends WidgetInfo state to provide information about rich text.

Required Methods

fn rich_text_root(&self) -> Option<WidgetInfo>

Gets the outer most ancestor that defines the rich text root.

fn rich_text_component(&self) -> Option<RichTextComponent>

Gets what kind of component of the rich text tree this widget is.

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

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

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

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

fn rich_text_selection( &self, a: WidgetId, b: WidgetId, ) -> impl ExactSizeIterator<Item = WidgetInfo> + 'static

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

The iterator is over a..=b or if a is after b the iterator is over b..=a.

fn rich_text_selection_rev( &self, a: WidgetId, b: WidgetId, ) -> impl ExactSizeIterator<Item = WidgetInfo> + 'static

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

The iterator is over b..=a or if a is after b the iterator is over a..=b.

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

Iterate over the prev text/leaf components before the current one.

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

Iterate over the text/leaf component and previous.

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

Iterate over the next text/leaf components after the current one.

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

Iterate over the text/leaf component and next.

fn rich_text_line_info(&self) -> RichLineInfo

Gets info about how this rich leaf affects the text lines.

fn rich_text_nearest_leaf(&self, window_point: PxPoint) -> Option<WidgetInfo>

Gets the leaf descendant that is nearest to the window_point.

fn rich_text_nearest_leaf_filtered( &self, window_point: PxPoint, filter: impl FnMut(&WidgetInfo, PxRect, usize, usize) -> bool, ) -> Option<WidgetInfo>

Gets the leaf descendant that is nearest to the window_point and is approved by the filter.

The filter parameters are the widget, the rect, the rect row index and the widget inline rows length. If the widget is not inlined both index and len are zero.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
