Want I want is a way to implement this in the Qgis map canvas similar to what you can do in GRASS. Is there a way to connect the display monitor to Qgis's map canvas that I am not aware of? That would be useful if grass commands from the GRASS shell would display on the map canvas, but I am not able to run 'd.vect map=xxx rgb_column=yyy' and get output to Qgis from the GRASS Shell in the GRASS Tools plugin. Instead I get the error: No graphics monitor has been selected for output. Please run "d.mon" to selected a graphics monitor. No graphics device is selected.

[Qgis-user] Vector RGB color assignment
Hello All, I was wondering if there was a method for assigning vector polygon fill colors with an RGB column or columns? This would be similar to GRASS's assignment using the grassrgb column as R:G:B (e.g., 10:120:255). My searches have not found anything, but perhaps someone has created a plugin to accomplish this. If not, perhaps I will try my hand at learning some plugin development. Thanks, John ___ Qgis-user mailing list Qgis-user@lists.qgis.org http://lists.qgis.org/cgi-bin/mailman/listinfo/qgis-user

Hi, that's true, however access to this database is not encapsulated by QGIS API so far, thus it would be a bit rough to use...

In fact you can use QGIS project files to save plugin-specific data for a plugin - see QgsProject class. In case you'd like to be able to use one set of annotation for different project it would be wiser to save them separately - in a file or a database. Using files for saving annotations (e.g. with python serialization) should be easier to use for user as they won't need to set up a database/table for them etc. And actually user would expect that annotation plugin should work also without postgres database.
