Hi Alessandro

I just downloaded the latest nightly build and will make some tests in the
coming days. What would be the most efficient / useful way to give you
feedback and comments? On this thread?

Thanks and cheers

Stéphane

 Hi,

 a quick update:

 I've prepared a PR with a working prototype in
 https://github.com/qgis/QGIS/pull/4629, I need some feed-back and some
 help, expecially UX/UI about if we want it as a dockable dialog too (and
 how to make it user-configurable).

 Feed-back welcome (but please keep it limited in scope to phase 1).

 Cheers

Re: [QGIS-Developer] PyQGIS: Check if layer is already loaded?

2017-06-04 Thread Siki Zoltan 

Dear Magnus.

you can iterate through the layers:

for lay in QgsMapLayerRegistry.instance().mapLayers().values():
if lay.name() == your_layer_name:
your layer is loaded

Zoltan

Is this even possible?

[QGIS-Developer] PyQGIS: Check if layer is already loaded?

2017-06-04 Thread Magnus Homann 

I'm writing a plugin that adds feature to a SHP-layer, specified as a filename.
If the layer already is loaded in Qgis, I want to check for and use the loaded
layer instead of creating a new from the same SHP-file.

Is this even possible?
