Struct DragSelect
pub struct DragSelect { /* private fields */ }Expand description
Tracks a text-selection drag gesture across press → move → release, including multi-click (word/line) and shift-extend.
Implementations§
§impl DragSelect
impl DragSelect
pub fn new() -> DragSelect
pub fn press(&mut self, pos: Point, shift: bool) -> PressIntent
pub fn press(&mut self, pos: Point, shift: bool) -> PressIntent
Begin a gesture at pos. Returns whether to extend the existing selection
(shift held) and the granularity from the click count. A shift-press is
never a multi-click — it always extends at char granularity.
pub fn drag(&self) -> Option<Granularity>
pub fn drag(&self) -> Option<Granularity>
While dragging, the granularity to extend the selection to the current
pointer with (the app keeps the anchor and moves the caret). None when
no drag is in progress.
pub fn is_dragging(&self) -> bool
