Bug report #10130

updating display when file based layer change (external to qgis).

Added by John Floyd - almost 10 years ago. Updated almost 5 years ago.

Affected QGIS version:2.2.0 Regression?:No
Operating System:linux (fedora) Easy fix?:No

Crashes QGIS or corrupts data:No Copied to github as #:18589


Not sure whether this should be viewed as a bug or a feature request.

I have a number of file based layers that are updated by external programs, whilst still running qgis. I have found that qgis does not update the canvas when changes are made to the files (which I understand). I find that I either need to reload the project or remove that layer and re-establish it - this is messy. I have experienced this for both shapefiles and raster files - I think that postgis layers do not have this trouble.

Delimited text files have a watchfile option. This would also be useful for other layer types.

Or an option (possibly) in the layer properties menu to reread/refresh that layer. This keeps all the display attributes. This is similar to the re-calc layer extents button in the properties - general tab.

If these already exist - great but where are they.

Great Work.
