Re: [Qgis-user] Very slow performance with large SHP files, with over 200k objects

Shouldn't the rendering speed of complex projects be improved with the upcoming threading improvements of Martin? At least in the case where are multiple layers in one redraw? Andreas On Wed, 09 Mar 2011 08:24:42 +0100, Paolo Cavallini wrote: Il giorno mar, 08/03/2011 alle 19.16 +0100, Agusti

Re: [Qgis-user] applying symbology to multiple layers in a "group"

Alexander,   Okay, now I see it and it is working.  I was trying to place the line *on* the group icon and not below it, so the layer would jump above the group.  The images were very helpful.    Thank you very much.

Porting fTools to C++ is already under way, but it is extremely slow at the moment (due to my PhD!). If there are any C++ devs out there with an interest in speeding these operations up, please don't hesitate to contact me! My other comment, which is frequently given on the R mailing lists, is thi

Jim, I take two screenshots of the adding layer to group. Here is first http://img810.imageshack.us/img810/4568/belowgroup.png Blue line below group and touched both sides of the layer list widget. When you move layer a bit upper this should be looked as http://img13.imageshack.us/img13/8319/ingr

Re: [Qgis-user] Very slow performance with large SHP files, with over 200k objects

At least regarding the vector operations (ftools), it seems that the slowness is because of python code. During FOSS4G in Barcelona we raised the question of rewriting all that part in c++ Agus 2011/3/7 Giovanni Manghi : > >> Agreed, this is a serious problem, and should be dealt with. There is a

Okay, thanks.  I see the blue line but it always appears above or below the group.  It will not let me drag it to the group itself.   I'll keep experimenting. Thanks for the help. On 03/08/2011 10:37 AM, Alexander Bruy wrote:

[Qgis-user] applying symbology to multiple layers in a "group"
