|
Methods in this class are used to handle basic operations on vector layers.
|
|
With an implementation of this class, parts of the application can ask for
|
|
an operation to be done and the implementation will then take care of it.
|
|
|
|
Reimplement this class, if you need to have custom checks or GUI elements
|
|
in your application.

This method should/will be called, whenever a new feature will be added to the layer
|

\param defaultGeometry A default geometry to add to the feature
|

\param feature Updated feature after adding will be written back to this

This will be called, whenever a vector layer should be switched to edit mode. Check the providers

capability to edit in here.

If successful layer->startEditing() will be called and true returned.

Will be called, when an editing session is ended and the features should be committed.
|

Appropriate dialogs should be shown like

Copy and move features with defined translation.

\param errorMsg If given, it will contain the error message
