[Qgis-user] MapInfo tab files?

[Andreas Neumann]

 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.
