[Qgis-user] Click to open layer

[Richard McDonnell]

Hi Grant,
Do you mean insert a GeoTIFF in?
If that's the case, then you want the following Action..

Type: Python
Description: Add Raster to Canvas or whatever you want
Action Text: qgis.utils.iface.addRasterLayer('[%filepath%][%filename%]','[%filename%]')

For the above to work, you will need two attributes in your Polygon, a "filepath" and a "filename" attribute. In the fileparh is the Path to the folder containing the GeoTiff and the filename is the name of the file you are looking to load... so something like this...

This should then load any GeoTIFF into your Canvas.
Kind Regards,

Richard

I am sure there is a simple way to do this but I would like to click on a polygon and get it to open a tiff file into my map canvas. Do I use an Action and an "open" command?
