Don't know how to do that using the GUI, but for the opacity you can use
these 2 lines of python in the QGIS python console. It will set all your
selected layers to 50% opacity.
for layer in iface.layerTreeView().selectedLayers():
layer.setOpacity(.5)
I think the stroke style is harder t
Hi Gert-Jan,
Not sure how exactly you are filtering your data, but to create views
you can run these queries on your PostgreSQL database using the tool you
like (for example DB-manager in QGIS, or DBeaver or PGAdmin).
In case this is an SQL query filter:

Hi Roland,
You could either go making SQL queries (using st_startpoint() and
st_endpoint() et cetera) or have a look at the "Networks" plugin which
has a lot of this kind of functionality.

And there are several other network and topology related plu

In an expression you can use the coalesce() function:

Some things to check:
* Is your data local?
* Is it in a fast file format? (for example .gpkg or .shp and not .csv
or .geojson)
* Does the data have a spatial index?
* Is the geometry very complicated, like a huge multi polygon with
thousands of vertices and islands? In that case, split it up

Yes, all free! Use as much QGIS as you like!
However, if you are happy QGIS users and your organization is relying on
the software, consider becoming a sustaining member. That way you can
support the project, software development, bug fixing, upgrades and so on.

Hi Adam,
Normally it should work as you wish for.
Once I had a customer with this problem. They were using Citrix and the
user home directory (where plugins are stored) was either cleared at
every startup, or the server where QGIS was running was a different
every time. Could that be the prob
Haven't tried, but maybe 1:1 joining a second table to your layer and
editing that table might work?

Just guessing.. You're trying to export your layer and when you chose a
file name you just typed it into the edit widget and did not choose the
[...] button next to it to open file browser. Now QGIS will attempt to
save your gpkg file in the installation folder or some other directory
where you

Didn't do any inverstigation, but I'm pretty sure that only the layer

Hi Mike,
I'm afraid you cannot add submenus to the plugin menu.
The addPluginToMenu function only takes actions as an argument:
action_1 = QAction('Action 1')
iface.addPluginToMenu('Plugin 1', action_1)
menu_1 = QMenu('Menu 1')
iface.addPluginToMenu('Plugin 1', menu_1)

Wow, this is so much more logical!
If this works, then why do we (still) have the addPluginToMenu() available?
