SVG paths

[drnextgis]

It seems like looking up of SVG icons in custom paths doesn't work in nextgisqgis. I've discovered it while working with nextgisweb. Here we add paths to list of paths where QGIS should be able to search SVGs https://github.com/nextgis/nextgisweb_qgis/blob/ffce27d0055f5344907f29681021597f313e1405/nextgisweb_qgis/__init__.py#L81-L89. It works in official QGIS but not in nextgisqgis. The one way I was able to overcome this issue is to create /ngw/management/env/share/ngqgis/svg/ directory and put icons there.

On MacOS not reproduced.

>>> from qgis.core import QgsApplication
>>> qgis = QgsApplication([], False)
>>> qgis.svgPaths()
[u'/System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Applications/qgis-ng.app/Contents/Resources/svg/', u'/Users/Bishop/.qgis2//svg/']
>>> qgis.setDefaultSvgPaths(qgis.svgPaths() + ['/svgpaths'])
>>> qgis.svgPaths()
[u'/System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Applications/qgis-ng.app/Contents/Resources/svg/', u'/Users/Bishop/.qgis2//svg/', u'/svgpaths']
>>> from qgis.PyQt.QtCore import QSettings
>>> QSettings().value( 'svg/searchPathsForSVG' )
>>> QSettings().setValue( 'svg/searchPathsForSVG', '/svgpaths2' )
>>> qgis.svgPaths()
[u'/svgpaths2', u'/System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Applications/qgis-ng.app/Contents/Resources/svg/', u'/Users/Bishop/.qgis2//svg/', u'/svgpaths']

Let me test on ubuntu.

On ubuntu:

>>> from qgis.core import QgsApplication
>>> qgis = QgsApplication([], False)
>>> qgis.svgPaths()
[u'/usr/share/ngqgis/svg/', u'/opt/ngw/.qgis2//svg/']
>>> qgis.setDefaultSvgPaths(qgis.svgPaths() + ['/svgpaths'])
>>> qgis.svgPaths()
[u'/usr/share/ngqgis/svg/', u'/opt/ngw/.qgis2//svg/', u'/svgpaths']
>>> from qgis.PyQt.QtCore import QSettings
>>> QSettings().value( 'svg/searchPathsForSVG' )
>>> QSettings().setValue( 'svg/searchPathsForSVG', '/svgpaths2' )
>>> qgis.svgPaths()
[u'/svgpaths2', u'/usr/share/ngqgis/svg/', u'/opt/ngw/.qgis2//svg/', u'/svgpaths']
>>>

I can confirm, that this list populates as expected but QGIS doesn't take into account some of these paths. @BishopGIS try to render an image programmatically using custom SVGs.

Can you check the second case to set custom svg path:

>>> QSettings().setValue( 'svg/searchPathsForSVG', '/svgpaths2' )
>>> qgis.svgPaths()
[u'/svgpaths2', u'/usr/share/ngqgis/svg/', u'/opt/ngw/.qgis2//svg/', u'/svgpaths']

It this not working too?

For first case I think I found out the root of problem.

Default svg icons path /usr/share/ngqgis/svg/ also works.
