Right, I've implemented the flag over in https://github.com/qgis/QGIS/pull/4734

This opens the possibility of using a COPY statement in the postgres
provider when FastInsert flag is set. I haven't done that, so
presuming the PR is acceptable it'd be a good time for someone else to
jump in and make this improvement. All required changes would be self
contained in QgsPostgresProvider::addFeatures.

This would be great to have for 3.0 - we've already made huge
improvements in the speed of various related operations, and
implementing COPY for FastInsert would then also have massive flow on
benefits to processing algs which are saving their results direct to a
postgres database.

Re: [QGIS-Developer] Qt & Python version for QGIS 3

[Tom Elwertowski]

For QtWebKit, I created and used a build subdirectory inside the source 
directory:


export QT5DIR=/Applications/Qt/5.9/clang_64
alias qmake=$QT5DIR/bin/qmake
qmake ../WebKit.pro

For PyQt, in the source directory:

python3 configure.py --qmake=/Applications/Qt/5.9/clang_64/bin/qmake

Both followed by 'make' and 'sudo make install'

Re: [QGIS-Developer] Qt & Python version for QGIS 3

How did you build QtWebkit 5.9, or PyQt?  I have the Qt 5.9 binaries, built 
QtWebkit 5.9 from the Qt project version of the source, but qmake doesn't see 
it when building PyQt 5.9 (dev).  qmake says:

Project ERROR: Unknown module(s) in QT: webkit

Note that at least since proj 4.9.0, Charles Karney has ported its geodesic 
code from 
geographiclib in C (since proj.4 is C only) and the header is normally 
installed with proj-dev 
package (I've just checked on my Ubuntu 16.04 with proj 4.9.2. I see it is also 
available in 
OSGeo4W):

This looks relevant:

There's a lot of unrelated changes in there, but it also shows the
basics for using geographiclib within the QGIS c++ code.

[QGIS-Developer] Bug with Statist plugin

[Patrice]

There is a bug with the Statist plugin.

-

The plugin is broken. Python said:
cannot import name NavigationToolbar2QTAgg

-

As suggested by user'spaceof7'  on github, changing line 49

from matplotlib.backends.backend_qt4agg import NavigationToolbar2QTAgg 
as NavigationToolbar

to:
from matplotlib.backends.backend_qt4agg import NavigationToolbar2QT as 
NavigationToolbar



fixes the problem.


The git repository doesn't seem up to date (last update is from 2013.) 
and code has obviouslychanged since (when comparing sources).

[QGIS-Developer] Building QGIS on Windows 7

[C Hamilton]

I am attempting to build QGIS on Windows 7 and am getting errors in the
cmake-gui. I followed the general instructions found here:

https://github.com/qgis/QGIS/blob/master/INSTALL

When I run "Configure" in cmake-gui it cannot find:
Qt5Core_DIR
Qt5Gui_DIR
SPATIALINDEX_LIBRARY

This is the message:

CMake Error at CMakeLists.txt:249 (FIND_PACKAGE):
By not providing "FindQt5Gui.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Qt5Gui", but
CMake did not find one.

Could not find a package configuration file provided by "Qt5Gui" with any
of the following names:

Qt5GuiConfig.cmake
qt5gui-config.cmake

Add the installation prefix of "Qt5Gui" to CMAKE_PREFIX_PATH or set
"Qt5Gui_DIR" to a directory containing one of the above files. If "Qt5Gui"
provides a separate development package or SDK, be sure it has been

Re: [QGIS-Developer] multipartToSingleParts via code

[Stefano Masera]

Hi Ben and Nyall, 
thanks for your answers. 
I resolve the question with the Nyall's processing link and using a part of the 
code in that link. 
It's a little bit difficult for me explain better what's happened because my 
plugin it's articulated (for my experience), and the multiparttosinglepart is a 
little part of the code. 
You can see the actual version installing it from the official repository, the 
name is "opeNoise", but in the actual there isn't this problem because I didn't 
need to use multiparttosinglepart. 
Now I'm workinkg to a develop of the plugin. 
In any case now it's all ok, even if I didn't use processing algorithm in the 
code. 

Thank you very much! 

Bye 
Stefano

Oggetto: Re: [QGIS-Developer] multipartToSingleParts via code 

Hi Stefano. 

Correct me if I'm wrong but my understanding is that you want to be able to 
call "multiparttosingleparts" in his code the same way you call dissolve. 

Something like: 

from qgis.xxx import * 
xxx = YYY 
xxx.multiparttosingleparts(input, output) 

Have you tried looking at the API? 

I haven't used the qgis processing algorithims in my Python code that way since 
they already work fine the way they do now. May I know why you'd like such a 
use case?

Ben Hur

Re: [QGIS-Developer] [Qgis-developer] Processing UI looks strange

[Frank Sokolic]

Hi Etienne,

Are you referring to this issue: https://issues.qgis.org/issues/16428

I have still got this problem and as a result can't use or test 
processing on Master.

Re: [QGIS-Developer] [Qgis-developer] Processing UI looks strange

[matteo]

HI Etienne,

well I get some installation and reinstallation and messing things up in
my computer so I don't have this problem anymore. Here what I did.

I get some "issues" when designing UI plugins interface with Qt and
using the Qgs Widgets: every time I save the UI in QT Designer, all he
QgsWidget are saved for example as something like qgscollapsible.h and
QGIS is not able to load them.
So I have to manually enter the UI file and replace all the qgs.h
with qgis.gui

This started to happens when I removed the qgis_customwidgets.py file
from the plugins directory Qt
(/usr/lib/python2.7/dist-packages/PyQt4/uic/widget-plugins/).
Removing this file from there seems to let Processing UI looks fine
while you get this small problem with the qgs widget in QtDesigner

Hope this helps
Cheers

Matteo

here you go:

https://web.archive.org/web/20160623213331/https://hub.qgis.org/wiki/quantum-gis/Python_plugin_API_changes_from_18_to_20

This could be migrated to the api docs (in the qgis source code) where
we the changes from QGIS 2 to QGIS 3 are maintained as well.

Re: [QGIS-Developer] multipartToSingleParts via code

[Ben Hur Pintor]

What do you mean by *"The plugin runs correctly only the FIRST time.*
*Then, when it finishes, if I run again the plugin choosing an input2
vectorlayer, the processing algorithm doesn't see the input2 and my ouput
remains output1."? *

Are you calling the algorithm inside a loop? May I have a look at your
code? Maybe the issue is in the Python code and not necessarily on QGIS.

I usually use *processing.runandload()* because it automatically adds the
resulting layer.

Regards,

Ben Hur

Hi Chris,

Yep, they are archived. We moved and upgraded Redmine from hub.qgis.org
to issues.qgis.org and retired the wiki and older projects.

If you really need it I can dig it up from the database dump we created
for the move.

Just let me know.

Regards,

Richard Duivenvoorde
