Is it possible to determine, from one widget, whether another widget is active?
For example, in my new widget's startup function, can I tell whether the Scalebar widget is active?
Inactive:
Active:
Stephen,
You check for the "visible": false (inactive) property when looping through the appConfig.

Robert I am trying to use this script to check if a widget is open and it is then to close it. But I run into problems. The error is:
Uncaught TypeError: Cannot read property 'style' of null
I don't know why I get this since I trying to close the widget only if it is open. AM I missing something?
Also, the script check if it is visible. Is that means just visible on the screen or open?
Thank you.

Lefteris,
The issue I see in your code is this:
WidgetManager<SPAN class="punctuation token">.</SPAN><SPAN class="token function">getInstance</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">.</SPAN><SPAN class="token function">closeWidget</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">[</SPAN><SPAN class="number token">0</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="line-numbers-rows"><SPAN></SPAN></SPAN>
It should be:
WidgetManager<SPAN class="punctuation token">.</SPAN><SPAN class="token function">getInstance</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">.</SPAN><SPAN class="token function">closeWidget</SPAN><SPAN class="punctuation token">(</SPAN>wc<SPAN class="punctuation token">.</SPAN>id<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN></SPAN></SPAN>
Thank you. Sometimes the answer is staring at you...
I got a bizarre behavior. Instead of closing the widget, it empties the content of all UI components!! ???
