[Qgis-user] Readonly geometries

[Ludwig Kniprath]

Oh my, QGis without GIS functionalities...


Not with on-board resources, I'm afraid, but some thoughts:


In QGis/PyQGis (script/plugin):

- connect the QgsVectorLayer::editingStarted-signal to 
disable/remove/hide the vertex-tool-icon and the "Advanced Digitizing 
Toolbar"

- connect the QgsVectorLayer::geometryChanged-signal emitted on 
geometry-change to restore the original geometry or make a rollback


In case of a server-client geo-database (f.e. PostGres/PostGis):

- implement a fine grained access control with dedicated 
users/permissions and revoke the update-privilege from geometry-column 
for some users

- implement a database-trigger, which prevents altering geometries


Just some ideas, there are certainly many more ...

Ludwig
