Hello,
Is the functionality to filter a layer via query builder an option for ArcGIS
based service layers, within the layer's properties, Query Builder is disabled?
Looks like not according to this (link below), but just wondered if any updates
on that being resolved. Or are there

Have you tried the plugin ‘Go2NextFeature3’. It is very useful, allows you to

Hello,
I am struggling to get something to work, which would seem to be an easy thing
to do, but cannot quite make my understanding of the python docs work in
practice.
What I would like to do, is run some python to add some folders to the
favorites area in the browser within QGIS. This is to
:
is_selected( $currentfeature )
which then makes your selected features draw last (on top).
You could at least try that.
I'm wondering if that would/could not be default painting behaviour?

Is there a set of steps I can follow in QGIS and PostGIS in order to have QGIS

example I have some stops (bus) and associated timetable
That will vary on what level of licensing you have for ArcGIS. If you are on a
Basic license then you will probably find QGIS will fill in quite a lot of gaps
in your functionality. Off the top of my head these would include Erase /
Difference geoprocessing and some proximity analysis.

Is there a setting that controls whether features when selected by expression

selected/highlighted features will always be at the top of the list. The
attribute table has buttons at the top to zoom & pan to selected features...

I would like to use QGIS as a visual / interactive front to some PostGIS data
and am not sure what the best route to doing so is. Happy to explore further
myself, but wanted to get some input on what needs to be joined up to get
started on building a little process.
Basically, if I wanted to
and a
single feature in another, which overlaps two of the 3, results in 6 features
when unioning which makes some sense.

I was doing some analysis on UNION against the same feature (on itself) to get

Which version of QGIS are you using? The later ones (certainly 2.12) allows use
of a Virtual Attribute. In field calculator – check the box for ‘create virtual

itself accordingly.
