Re: [QGIS-Developer] Programmatically iterate over features with Processing in QGIS 3

[DelazJ]

Hi,

Thanks Nyall. If it uses the same getFeatures method (already shown
multiple times) then I'll remove that example.

Regards,
Harrissou

[QGIS-Developer] Issues with QGIS 3 rotate tool

[C Hamilton]

If I try to rotate an EPSG:4326 vector object, I get the nice outline while
rotating, but when I click to complete it, the shape is badly misshapen


If am guessing it is because of being in 4326, but the problem is what you
see while rotating is not what you get as the final result. If I do the
same with something like a UTM projection then it works correctly.

What is the intended operation of the tool? It shouldn't show one thing
while rotating and then deliver a different result. I am guessing that the
move tool may also be distorting shapes, but I have not really looked at it.

Do I need to write a geodesic move and rotate tool as part of the Shape
Tools plugin?

Thanks,

Calvin

[Peter Petrik]

Hi,

look at this thread

I suggest to use https://github.com/OSGeo/homebrew-osgeo4mac

Kind regards,

Re: [QGIS-Developer] Use QGIS API in Qt5

[David Marteau]

Hi,

Qgis 3 use Qt5  and Python 3.5+ , if you use Qgis 2 api then you have to use 
Qt4.

You have the Qgis API  documentation here: https://qgis.org/api/

How do you install qgis ? homebrew, macport, custom build or from 
https://www.qgis.org/fr/site/forusers/download.html ? the exact version of Qt 
Qgis depends on may vary with the distribution.

[QGIS-Developer] Use QGIS API in Qt5

[Dave Barter]

I want to build a very basic desktop map application using the QGIS API. 

My development environment is currently Mac OSX High Sierra and Qt5. 

I’m struggling to find any developer documentation to get me started and the 
GitHub repo suggests OSX builds of QGIS need Qt4.

Can my objective be achieved? If so can anyone point me to some docs to get me 
started

Hi Debian fans,

Fyi: libqt5network5_5.11.1+dfsg-8_amd64.deb is in testing and working!!

Enjoy QGIS and Debian :-)
