[Qgis-user] Field Calculator: dynamic calculations

[Peter Schürch]

Hi all,
How would I implement a dynamic calculation with the field calculator? With dynamic I mean that the result would change as values change in the input fields. With a Shape file, the result field obviously only contains the numerical result of any calculation and when the input changes I have to retype and re-execute the calculation in the field  calculator.
In other GIS-Systems I have used this would be called a query.

Thanks for any input on this.
Peter
