Struct LabelSelectionState 

pub struct LabelSelectionState { /* private fields */ }

Handles text selection in labels (NOT in crate::TextEdit)s.

Each viewport has its own state, because viewports are rendered in separate passes.

Implementations

impl LabelSelectionState

pub fn has_selection(&self) -> bool

Is there a label text selection in any viewport?

pub fn clear_selection(&mut self)

Clear all label text selections in all viewports.

pub fn label_text_selection( ui: &Ui, response: &Response, galley_pos: Pos2, galley: Arc<Galley>, fallback_color: Color32, underline: Stroke, )

Handle text selection state for a label or similar widget. This also takes care of painting the galley.
