Can I ask why you are reinventing the wheel and no just using the QGIS libs as a base.<div><br></div><div>- Nathan<br><br><div class="gmail_quote">On Wed, May 9, 2012 at 11:29 PM, akshay gupta <span dir="ltr"><<a href="mailto:akshaygupta202@gmail.com" target="_blank">akshaygupta202@gmail.com</a>></span> wrote:<br>

I am new to dealing with vector files, I am not able to decide how to render them on GUI. Few approaches that come to my mind are: <br>
- To convert vector files to raster and display them as raster..<br>- To draw each shape in vector file one by one (i dont know how to do this, I dont even know whether it would be even possible this using GDAL/OGR, or how complex this would be because in my case vector files can be very complex)<br>
<br> The decision how to render vector files is very important for me, because after displaying vector files i need to support some advanced features like projection change, interactive selection, Geo-referencing etc.<br>
<br>Can any one who has worked on vector/gis stuff, tell me how this is usually done and what Qt widget is used for displaying such data.<br><br>Thanks,<br>Akshay gupta<br><br>
