Function sendTouchEvent

Dispatch a touch event to the currently selected tool. Intended for unit tests.

See

sendPenEvent

Example

Simulating a horizontal swipe gesture:

sendTouchEvent(editor, InputEvtType.PointerDownEvt, Vec2.of(0, 0));
for (let i = 1; i <= 10; i++) {
  jest.advanceTimersByTime(10);
  sendTouchEvent(editor, InputEvtType.PointerMoveEvt, Vec2.of(i * 10, 0));
}

Example

Simulating a pinch gesture. This example assumes that you're using Jest with timer mocks enabled.

let firstPointer = sendTouchEvent(editor, InputEvtType.PointerDownEvt, Vec2.of(0, 0));
let secondPointer = sendTouchEvent(editor, InputEvtType.PointerDownEvt, Vec2.of(100, 0), [ firstPointer ]);

// Simulate a pinch
const maxIterations = 10;
for (let i = 0; i < maxIterations; i++) {
  // Use the unit testing framework's tool for increasing the current time
  // returned by (new Date()).getTime(), etc.
  jest.advanceTimersByTime(100);

  const point1 = Vec2.of(-i * 5, 0);
  const point2 = Vec2.of(i * 5 + 100, 0);

  firstPointer = sendTouchEvent(editor, InputEvtType.PointerMoveEvt, point1, [ secondPointer ]);
  secondPointer = sendTouchEvent(editor, InputEvtType.PointerMoveEvt, point2, [ firstPointer ]);
}
