Struct DragDropConfig 

pub struct DragDropConfig {
    pub drag_delay: Duration,
    pub scroll_tolerance: Option<f32>,
    pub click_tolerance: f32,
    pub click_tolerance_timeout: Duration,
}

Configuration for drag detection.

Fields

drag_delay: Duration

How long does the user have to keep pressing until a drag may begin? This is useful when dragging and dropping on a touch screen in a scrollable area.

scroll_tolerance: Option<f32>

How far can the pointer move during the DragDropConfig::drag_delay before the drag is cancelled?

click_tolerance: f32

How far does the pointer have to move before a drag starts? This is useful when the handle is also a button. If the pointer is released before this threshold, the drag never starts and the button / handle can be clicked. If you want to detect clicks on the handle itself, Handle::sense to add a click sense to the handle.

click_tolerance_timeout: Duration

If we have been holding longer than this duration, a drag will be started even if the pointer has not moved above DragDropConfig::click_tolerance.

Optimized for mouse usage

pub fn touch() -> Self

Optimized for touch usage in a fixed size area (no scrolling) Has a higher click tolerance than DragDropConfig::mouse

pub fn touch_scroll() -> Self

Optimized for touch usage in a scrollable area
