[Qgis-developer] Feature-request/idea: timely data-source updates

[Richard Duivenvoorde]

Hi,

I got a question from somebody to write a python plugin which retrieves
features via a (simple) WFS-request.
BUT, data being moving items, IF it was possible to update that layer
once every x minutes.

Off course this is in this case pretty easy (I think) doable via a
python plugin...

BUT I was wondering if there would be interest into making this maybe an
integral part for every dataprovider or maplayer?

For example for every layer  in QGIS there is an option in the
properties (and an api-call via layer.setUpdateTime(onlyVisiblePart) or
layer.setValidity(onlyVisiblePart) or so) to let the layer update it's
data every x minutes..... (if possible via some fancy graphic
visualisation like fade in the new one / fade out the old one ;-) )

This would voor example make it possible that a QGIS window stays open and:
- a database is updated
- a raster file/source is updated everytime
- a vector file is updated
etc etc

Anybody thinks there is an interest in this (or do I just miss something
and is this already available???)?

Regards,

Richard Duivenvoorde
