[Qgis-developer] Installation problems in QGIS 2.8.3 on Windows 7 - 64 bit
Hi, I'm encountering installation problems with the LTR version of QGIS. While QGIS 2.8.2 installed fine, the QGIS 2.8.3 has these problems: - the start menu folder QGIS Wien is empty (no icons) - the BAT files are not generated after installation: in the C:\Program Files\qgis\bin there are many templates like: qgis-ltr.bat.tmpl Could you check this? ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

Re: [Qgis-developer] memory layer performance while adding many features?
Hi Denis, Adding all features at once, or 1000 by 1000, speeds up enormously. It only takes a few minutes, at a steady speed of 480 fpm. Where adding the same dataset 1 by 1 took about 5 hours. Thanks for pointing this out!

[Qgis-developer] Compiling ui files with custom widgets creates wrong imports
Hi, There seems to be an issue with custom widgets in Python. For example this plugin bug: ImportError: No module named qgsfieldcombobox ( https://github.com/informeren/qgis-cartogram/issues/2) Compiling with pyuic4 -o cartogram_dialog_base.py cartogram_dialog_base.ui results in from qgsfieldcombobox import QgsFieldComboBox while it should be from qgis.gui import QgsFieldComboBox Is there some way to fix this on our side?

Re: [Qgis-developer] memory layer performance while adding many features?
Hi all, in general I think we should advice to use the layer.addFeature() method with a layer.commitChanges() in the end. It has the advantage that it does batch updates on the provider automatically and proper signals are sent so the UI (canvas, attribute table...) can reflect changes immediately. The layer.dataProvider().addFeatures() method delegates all this to the developer.

Re: [Qgis-developer] QGIS 2.10.1 Pisa - Read CSV file problem
Hi, In my opinion it is quite special to name columns with integer numbers. Not what the average GIS user would do. In my own 2-decade GIS career I never had such an issue. I am not against fixing this issue, but I don't think it is a serious issue. We have many more important issues in QGIS.
