Hi Zoltan and others,
QGIS has a second method to assign styles: using data-defined columns.
This is where OGR feature styling could be used. You assign certain data
columns to styling (e.g. font styles, positioning, dashing,
stroke-width). Label styling in QGIS is a good example where
data-defined columns work well.
Not everything is available yet for data-defined styling but
improvements are made.
BTW: reading of DXF would also benefit a lot from the support of OGR
feature styling.
It is really just the matter of funding or voluntary work to support
OGR feature styling. Not a major technical problem in my opinion. If
someone really cares about interoperability he should take the money or
time to invest in support of OGR feature-styling in QGIS. And if the OGR
feature styling is not good enough - also invest in OGR feature styling
improvements.

Dear Mats,
it is not only a driver support question. In MapInfo tab file the
style is stored for each map element in the tab file. QGIS follows
the
Shape file logic where no style information is stored besides the
geometry and atrributes. The only chance to have different styles for
the elements in QGIS is to create a thematic map.
AFAIK it is not possible to fill the gap between these two different
schema upgrading a driver, the QGIS should be redesigned.

Zoltan

Hi!
On the MapInfo list, someone wanted to know why map styles in a
MapInfo tab
file does not show in Qgis.
The answer was that the Qgis reader does not support it.
This is a pity since one of the tab file advantages is the ability
to store
map styles.
I would like to know if this is a deliberate decision by the Qgis
developer, or if the libraries that Qgis uses are the problem.
