Class: Gesture

Defined in: packages/blockly/core/gesture.ts:56

Class for one gesture.

Properties index​

PropertyDescription
startWorkspace_The workspace that the gesture started on. There may be multiple workspaces on a page; this is more accurate than using Blockly.common.getMainWorkspace().
isEnding_Boolean used internally to break a cycle in disposal.
currentDropdownOwnerThe owner of the dropdownDiv when this gesture first starts. Needed because we'll close the dropdown before fields get to act on their events, and some fields care about who owns the dropdown.

inProgressIs a drag or other gesture currently in progress on any workspace?
