<p>The Scatter in Tüsch specifies some classes to make them more suitable for Map applications.</p>
|
|
|
|
|
|
|
|
|
|
<h2>CoverScatter</h2>
|
|
|
|
|
<p>Usually maps should cover the whole app, or a window inside the app. Therefore they support a cover option. This option
|
|
|
|
|
allows prevents the scatter to move inside the window.
