DraggableState
Known direct subclasses
PaneExpansionState

This class manages the pane expansion state for pane scaffolds.
SliderState

Class that holds information about Slider's active range.

State of draggable. Allows for a granular control of how deltas are consumed by the user as well as to write custom drag methods using drag suspend function.

Summary

Public functions
Unit

Dispatch drag delta in pixels avoiding all drag related priority mechanisms.
Cmn
suspend Unit
drag(dragPriority: MutatePriority, block: suspend DragScope.() -> Unit)

Call this function to take control of drag logic.
Cmn

Public functions

dispatchRawDelta

Cmn
Added in 1.0.0
fun dispatchRawDelta(delta: Float): Unit

Dispatch drag delta in pixels avoiding all drag related priority mechanisms.

NOTE: unlike drag, dispatching any delta with this method will bypass scrolling of any priority. This method will also ignore reverseDirection and other parameters set in draggable.

This method is used internally for low level operations, allowing implementers of DraggableState influence the consumption as suits them, e.g. introduce nested scrolling. Manually dispatching delta via this method will likely result in a bad user experience, you must prefer drag method over this one.

Parameters
delta: Float

amount of scroll dispatched in the nested drag process

drag

Cmn
Added in 1.0.0
suspend fun drag(
    dragPriority: MutatePriority = MutatePriority.Default,
    block: suspend DragScope.() -> Unit
): Unit

Call this function to take control of drag logic.

All actions that change the logical drag position must be performed within a drag block (even if they don't call any other methods on this object) in order to guarantee that mutual exclusion is enforced.

If drag is called from elsewhere with the dragPriority higher or equal to ongoing drag, ongoing drag will be canceled.

Parameters
dragPriority: MutatePriority = MutatePriority.Default

of the drag operation
block: suspend DragScope.() -> Unit

to perform drag in
