Struct egui::text_selection::LabelSelectionState

pub struct LabelSelectionState { /* private fields */ }

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

One state for all labels, because we only support text selection in one label at a time.

Implementations

impl LabelSelectionState

pub fn load(ctx: &Context) -> Self

pub fn store(self, ctx: &Context)

pub fn has_selection(&self) -> bool

pub fn clear_selection(&mut self)

pub fn label_text_selection( ui: &Ui, response: &Response, galley_pos: Pos2, galley: &Galley )

Handle text selection state for a label or similar widget.

Make sure the widget senses clicks and drags.

This should be called after painting the text, because this will also paint the text cursor/selection on top.
