Wrong properties display for GRASS Raster

[jrm]

Properties of a GRASS raster are limited by defaut to Transparency/General/Metadata as the user can't modify things like color table without using grass' r.color.* tools but after loading non-grass raster, QGIS then display all the properties.

This behavior leads user to think that QGIS or their grass raster is broken, for example the grass raster display list with no item selected.

Steps to reproduce :

1. create a new project and open a grass dataset
2. load a grass raster, open its properties, then close it
3. load a non-grass raster, open its properties, then close it
4. reopen the grass' properties, it is now displaying the same ui than the non-grass raster

Replying to jrm:

Properties of a GRASS raster are limited by defaut to Transparency/General/Metadata as the user can't modify things like color table without using grass' r.color.* tools

this is because the GRASS rasters are no longer handled via GDAL. So you really need to have to use GRASS tools to configure/style them.

but after loading non-grass raster, QGIS then display all the properties.

This behavior leads user to think that QGIS or their grass raster is broken, for example the grass raster display list with no item selected.

Steps to reproduce :

1. create a new project and open a grass dataset

3. load a non-grass raster, open its properties, then close it
4. reopen the grass' properties, it is now displaying the same ui than the non-grass raster

confirmed. It is just enough to open the GRASS raster properties in QGIS, close the dialog and then reopen again.
