[Qgis-user] Refresh Layer at Interval not working

[Raymond Nijssen]

Hi Ayyala,

Since the option is in the tab called "Render" I think it will only 
re-render the layer and not reload the data.

I tried this:
- create 3 points in a geojson layer
- set a 2 sec refresh interval on it
- open the geojson file in a text editor and add an extra point
- save geojson
The extra point should show up within 2 seconds in qgis but it does not.

Even after panning or zooming it does not show up. I think it would if I 
used a postgis layer or a shp-file? Could this be dependent on the data 
format?


If you need an example of a refreshed layer, you can type "hackfests" in 
the Coordinate input at the bottom. It will show you the hackfest 
locations with "moving" markers.


@other users: Does QGIS have an option to reload data for a layer? In 
the GUI, similar to the "Update Extents" button?

Kind regards,
Raymond
