handled

: boolean
Gets or sets a value indicating whether this QueryContinueDragEventArgs is handled.
Note that this property needs to be set before the function synchronously returns. This means that setting the value in an async function after the first await or in an asynchronous callback, it cannot not be seen by the emitter of the event and the sender will consider the event as not being handled.
// wrong:
dragSource.addEventListener('query-continue-drag', async (evt) => {
  await something()
  evt.handled = true // will be set *after* all other event listeners have been invoked, only
})

// correct:
dragSource.addEventListener('query-continue-drag', async (evt) => {
  evt.handled = true // will be set immediately and 'mode' will see the change
  await something()
})
final

Property Value

true if handled; otherwise, false.
