pub struct DragController {
    pub drag: bool,
    pub pos: [f64; 2],
}

Controls dragging.

Fields

drag: bool

Whether to drag or not.

pos: [f64; 2]

The current positon of dragging.

Methods

impl DragController[src]

pub fn new() -> DragController[src]

Creates a new drag controller.

pub fn event<E: GenericEvent, F>(&mut self, e: &E, f: F) where
    F: FnMut(Drag) -> bool, [src]

Handles event.

Calls closure when events for dragging happen. If the drag event callback returns false, it will cancel dragging.
