Expand description

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.

Fields§

§selection: Option<CurrentSelection>

The current selection, if any.

§selection_bbox_last_frame: Rect§selection_bbox_this_frame: Rect§any_hovered: bool

Any label hovered this frame?

§is_dragging: bool

Are we in drag-to-select state?

§has_reached_primary: bool

Have we reached the widget containing the primary selection?

§has_reached_secondary: bool

Have we reached the widget containing the secondary selection?

§text_to_copy: String

Accumulated text to copy.

§last_copied_galley_rect: Option<Rect>§painted_shape_idx: Vec<ShapeIdx>

Painted selections this frame.

source

fn copy_text( &mut self, galley_pos: Pos2, galley: &Galley, cursor_range: &CursorRange, )

source

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.

source

fn cursor_for( &mut self, ui: &Ui, response: &Response, galley_pos: Pos2, galley: &Galley, ) -> TextCursorState

source

fn on_label( &mut self, ui: &Ui, response: &Response, galley_pos: Pos2, galley: &Galley, )
