I have an application which has to perform a HTTP request (which will handle some map transformations) before fetching WMS tiles from server.

Is there a way to pause TileWMS auto-refreshing after dragging the map?

Setting invisible or removing and adding the layer will work, but I don't want the layer to disappear while performing the HTTP request. I also tried setUrl('') but the layer will also disappear.

I also tried to read OpenLayers source code to define a property to be checked before performing the requests but I couldn't find in code where the requests are made.

  • Which version of Openlayers are you use? – winsent Dec 12 '15 at 21:44
  • Not bound to any specific version, it is a new app. If you know the answer for any specific version I'll be glad to see your solution. Even if it is in OpenLayers 2. – caiohamamura Dec 13 '15 at 14:58
  • you could try just telling the user there is a process going on. start a "processing graphic" or something and when the map bits load, hide the graphic when it finishes. A quick search found this: gis.stackexchange.com/questions/123497/… – user1269942 Jan 24 '17 at 19:03
  • This will go against my requirements of giving a sense of fluidity in the application, I don't want anything to appear or disappear, just the tiles being replaced smoothly with the new ones and not for every drag of the map appear a message of "loading..." or displaying a blank map while new tiles load. – caiohamamura Jan 24 '17 at 19:18

I found some documents that may be able to assist you.

In the source code, Line 167 there is the refresh line.

I found documentation for OL2 that goes into more detail. You may be able to use this as a reference for your application.

The latest API Docs for OpenLayers will be your best bet. You will need to change the option from the default of silent.
