[Qgis-user] Polygon colours in existing shape files.

[Andreas Neumann]

Hi Ramon,

What you describe is data-defined styling - taking the symbology options
from a db field.

In QGIS you can use this for label settings, like font-family, font-color,
position, styles, etc. - unfortunately this is not available for the
simpler task of styling polygons or lines.

It would be very useful to have this data-defined styling also for general
symbology options. Also the stroke-width would be a natural candidate for
data-defined styling.

Sorry for not being of better help.
