<div class="info">
|
|
The <i>TouchCompass</i> interaction is intended to be use on touch devices.
|
|
<br />
|
|
It lets you handle movement by dragging a touch compass.
|
|
<br/>
|
|
This example shows how to move a point on the map by dragging the compass thus the finger don't mask the point it is moving.
