Re: [QGIS-Developer] GSoC 2024 proposal : QGIS improve the graphical modeler UI and UX

2024-02-22 Thread Raymond Nijssen via QGIS-Developer

Wow Valentin, that plan looks awesome! I'm using both QGIS and Blender 
and often wondered if the QGIS modeler could be improved.


Good luck with work and kind regards,
Raymond

Hi qgis developers

My name is Valentin Buira, I'm a french student in urban planning and 
I'm interested in participating in this year Google Summer of Code to 
improve the graphical modeler.


In particular I am interested in improving the user interface(UI) and 
user experience (UX) of the graphical modeler based on my previous 
experience with other node-based applications. If you are familiar with 
Blender the inspiration will be obvious to you but I tried to adapt to 
the identity and features of Qgis like the expression engine.


You can find the proposal at the url : 
https://docs.google.com/document/d/1iXHMTylTHLljfHBITfuIfJzi4_4hpQifEvj5GkM8OCc/edit?usp=sharing 


So far I am happy with my proposal but I'm looking for feedback and 
suggestions, and also tips on the technical feasibility and the schedule 
of the proposal.


On a side note, I will be attending the local code sprint in Grenoble 
the 26 mars. Where I will also discuss this proposal in person.


Best regards,
Valentin Buira

This is the plugin that should get updated:

In any case, I think it would be worth opening an issue with your

[QGIS-Developer] My own LayoutItem not getting rendered unless ...

2023-09-11 Thread Raymond Nijssen via QGIS-Developer


Hi,

For a plugin I made my own type of layoutItem which renders some kind of 
special graph. However, when the code adds the item to a layout, the 
rectangle is there but the content does not get rendered.


Now when I run this line in the console:

layout_manager = QgsProject.instance().layoutManager()

the layout item does get rendered, and also every next layout works 
properly. I put the line of code just above my layout item's class 
definition and it solves the problem. But I'd like to know if this is 
the right approach and why this line of code is needed. (Or if this is a 
bug?)


Thanks!

Raymond

Re: [QGIS-Developer] Loading layer from specific table/view after running algorithm

Found the answer to my own question in old posts here. (Thank you Matteo!)

I have added this code to the processAlgorithm() function:

```
context.addLayerToLoadOnCompletion(
f'{gpkg_fn}|layername=my_view',
context.LayerDetails(
name='my_view',
project=context.project()
)

Seems to work at least.

[QGIS-Developer] FOSS4G Community Sprint

2023-06-15 Thread Raymond Nijssen via QGIS-Developer


To everyone attending FOSS4G 2023 in Prizren,

There won't be a QGIS Contributor Meeting connected to the FOSS4G 
conference this year. But there will be an OSGeo Community Sprint during 
the weekend after the main conference (July 1+2). This is a "contributor 
meeting" for all OSgeo projects, so QGIS should be represented as it is 
the best, coolest, fasted, most widely used and most beautiful project 
in OSGeo, made by the smartest, nicest, funniest and most modest people!


Hope to see you there!

Hi developers,

While writing a python script in the QGIS python console editor I needed
to write a new class and for convenience I put that in its own python file.

Both files are in the same directory, but I cannot import my class in
the other script.

Here's an example:


# script_1.py

from .script_2 import TestClass
obj1 = TestClass('Ray')
print(obj1)




# script_2.py:

class TestClass():

  def __init__(self, name):
  self.name = name

  def __str__(self):
  return f'TestClass[{self.name}]'



It all works properly if I put my class definition in script_1 but as
the code is growing (and a customer of mine needs to understand this
too) it would really be nice to split the code over multiple files.
Is there a way? Or another approach?

Kind regards,
Raymond

Re: [QGIS-Developer] Multiple python scripts in python console?

2023-05-04 Thread Raymond Nijssen via QGIS-Developer


Hi Etienne,

Already tried what you are describing. Indeed it's inconvenient, and 
sometimes the changes in the class code did not end up in the class 
definition. For example, a newly defined function on the class was 
unknown in script_1. Might be a bug, but I'm not even sure.


So the best way should be to tell QGIS to run another python script in 
the console. Or go the plugin way.


Thanks and kind regards,

Raymond


On 04-05-2023 11:29, Etienne Trimaille wrote:
If you are talking about the simple Python console panel, and loading 
Python files from there, then you can skip the " from .script_2 import 
TestClass".


If you notice, when you launch the script_2.py, you have a generated 
line similar to :

exec(Path('/tmp/tmp5g244g4w.py').read_text())

So it's reading and executing all the content of file 2 in the console 
context already.
So then, when file 1 will be executed, there will already be the class 
TestClass in the console context.


But, then to manage multiple files, it's not convenient. You should 
think about the smallest plugin, for instance 
https://github.com/wonder-sk/qgis-minimal-plugin 
<https://github.com/wonder-sk/qgis-minimal-plugin> Otherwise, it's 
difficult to manage IMHO.

and run e.g. an overlap analysis, This algorithm adds a field 
'Buffered_pc'.


When I use the processing inside the QGIS desktop, the overlap 
algorithm names

the added field 'Gepuffert_pc', because I am using the German locale.

But I need for the further processing the German version of the field 
name.


Apparently qgis_process creates a file in ~/.config/Unknown Organization/
qgis_process.bin.conf with the content 
'localized_data_paths=@Invalid()'. It

seems to be that qgis_process expects somewhere the path for the German
localization.

How do I tell qgis_process to use the German locale?

Thank you for any hints.

Michael

Hi Raymond,
AFAIK you need to use setDataSource [1] directly on the layer an not 
setDataSourceUri on the data provider.

[QGIS-Developer] setDataSourceUri() not working

2022-12-08 Thread Raymond Nijssen via QGIS-Developer


Hi Devs,

I'm trying to change the dataSourceUri of an existing layer, but can't 
get it working. The reason is that my layer should be connected to 
another view in the same database, because the db should do some 
calculations for my plugin.


I created a test script for a simple polygon layer in a gpkg, which I 
attached to this email. The layer "polygons" and both views are all 
working correctly if you just drag and drop the gpkg in QGIS.


Open the polygons layer and select it. Then run:


layer = iface.activeLayer()
provider = layer.dataProvider()

ds = provider.dataSourceUri()
print(ds)

fn = ds.split('|layername=')[0]
new_ds = fn + '|layername=highest_3_view'
print(new_ds)

provider.setDataSourceUri(new_ds)




The first run displays 2 different dataSourceUris:
path/to/test_views.gpkg|layername=polygons
path/to/test_views.gpkg|layername=highest_3_view

The second run displays 2x the same dataSourceUris:
path/to/test_views.gpkg|layername=polygons
path/to/test_views.gpkg|layername=highest_3_view

So the string has been changed. But my layer properties still point to 
path/to/test_views.gpkg|layername=polygons


and the features displayed are all 5 from the polygons layer. (The views 
have only 3 features)




Should i do something after setting the new provider? I've been trying 
many things, including:

* provider.reloadData()
* layer.setDataProvider(dataprovider)
* refreshing/redrawing the layer


Hope anyone can help!
Raymond

Ok, I think I found the crux!

With your code QGIS 3.26 will CREATE a new geopackage... (if it is not there

After which QGIS master is fine

BUT QGIS master apparently does NOT create a new geopackage with your code...
So IF there is an excisting test.gpkg, all is fine
IF there is not one, it depends on you QGIS version if it creates a fresh one 
or not?

Maybe some core dev can say something about this?


I'd say the old behaviour was an unintentional bug, and that
createConnection should only be used with a path that already exists.

For 3.28 and later you can create empty databases using
QgsProviderMetadata.createDatabase(uri), eg:

QgsProviderRegistry.instance().providerMetadata('ogr').createDatabase('/path/to/data.gpkg')

After that you can create a connection to the db using createConnection safely.

Hi Raymond,

I've updated your test script a little:

gpkg_fn = '/tmp/test.gpkg'
try:
  print(QgsProviderRegistry.instance().providerList())
  md = QgsProviderRegistry.instance().providerMetadata('ogr')
  print(f'md = {md}')
  conn = md.createConnection(gpkg_fn, {})
  print(f'conn = {conn}')
  fields = QgsFields()
  fields.append(QgsField('key', QVariant.String))
  fields.append(QgsField('value', QVariant.String))
  conn.createVectorTable('', 'test', fields, QgsWkbTypes.NoGeometry, 
QgsCoordinateReferenceSystem(), True, {})
except Exception as e:
  print(f'ERROR: {e}')

As said: in my freshly compiled master, this fails to run with 'Could not 
retrieve driver for connection'
It also fails on my 3.28.0 version I have in a Windows VM.

It DOES print the 'ogr' driver in the providerList() though.

Strange behaviour: after starting (the older compiled) Qgis 3.26 on the same 
Linux system (in 3.26 the script always seems to work...) QGIS master ALSO 
works!!!

So I thought it had something todo with loading different provider registries 
or so?
Maybe master not having something but after starting 3.26 it was there?
Or is it loading (different) gdal/ogr libs order?
Did something change there?

Looking that the createConnection docs:
https://qgis.org/pyqgis/master/core/QgsConnectionRegistry.html#qgis.core.QgsConnectionRegistry.createConnection
I thought to see that your 'id' was only the filename, but adding ogr:// in 
front of it does not even work...
So not sure if that createConnection doc is old, or if I'm looking in the wrong 
createConnection...

Anybody can

Thank you Even. And that will always be available in QGIS? Without any

Let's say, I'm buying a brand new Windows laptop and install QGIS with

Hi Raymond

The general idea is that for every PyQGIS module (e.g. "core") there is 
a compiled python module (e.g. _core.so) and a directory acting as a 
module ("core") which imports the compiled module and adds some extra 
functionality (docstrings and more). So normally one wants to use import 
qgis.core instead of qgis._core.


Now with the 3d module things are not so great, because "3d" is not a 
valid module name because of the leading digit, so import qgis.3d simply 
won't work. There are some ways to work it around [1], but I wouldn't 
recommend using them. But as stated earlier, importing qgis._3d should 
generally do the job.


It is probably worth creating a ticket to address this, but I am not 
sure how to best fix it - probably the whole module should be renamed so 
avoid the leading digit - e.g. "threed"

Hi Andrea,

I know, but my script is not running in the console. It is part of a 
plugin, so I need to do the import. Would be handy if the documentation 
tells me how to do it.


Kind regards,

Re: [QGIS-Developer] Re-add Georeferencer action to raster menu?

2022-09-27 Thread Raymond Nijssen via QGIS-Developer


Hi Nyall,

I remember getting confused too. When searching for it, the things I 
tried were typing "georef" in the locator bar, in the processing toolbox 
(filter) and in the plugin manager. Not finding anything anywhere there. 
Maybe it would be possible to make that work?


For example all the menu items showing up in the locator?

Kind regards,
Raymond


On 27-09-2022 08:40, Nyall Dawson via QGIS-Developer wrote:

Hi devs!

I'm after some wider feedback -- in 3.26 I moved the "Georeferencer"
action from the Raster menu to the "Layers" menu, as the georeferencer
was expanded to support more than just raster layers and it no longer
seemed a logical place to put this action.

But we've seen a lot of confusion and bug reports about the missing
action since this move.

I'm pondering whether we should add a second shortcut to the
georeferncer back into the Raster menu, so that this tool will be
available through either location.

Is this a good idea and helps avoid user confusion? Or a bad one which
causes more UI bloat?

Re: [QGIS-Developer] Add algorithm to an existing provider?

2022-05-13 Thread Raymond Nijssen via QGIS-Developer


Hi Benjamin, thanks for your reply.

I'm not sure how the provider should "save a reference on my algorithm". 
What do you mean?


Some things I tried:


self.provider = TestProvider()
QgsApplication.processingRegistry().addProvider(self.provider)

alg2 = TestAlgorithm2()
alg2.setProvider(self.provider) # Maybe this is "setting a reference??

self.provider.addAlgorithm(alg2)

# Now the provider shows the extra algorithms (but not in the GUI)
print(self.provider.algorithms())

# Attempts to get it in the GUI:
self.provider.refreshAlgorithms()
self.provider.loadAlgorithms()
self.provider.load()


Still no luck!

Regards,
Raymond

Hi Raymond,

you need to ensure that your provider saves a python reference on your 
TestAlgorithm2() (which you probably already do).
After its set of algorithms has changed (i.e. refresh, addAlgorithm(s) 
etc.) it needs to emit the algorithmsLoaded signal.

I have 2 plugins and don't know if they are both installed (or which

Documentation is a bit brief on this:

QgsApplication.processingRegistry().addProvider(provider)

adds the group (=provider?) and the algorithms are in it.



What I want to do is finding the provider if it exists already:

self.provider = QgsApplication.processingRegistry().providerById('test')

This doesn't work, neither when doing:

I'm currently trial-and-errorring my way through this, but I hope

Re: [QGIS-Developer] Unexpected results from GPKG table query using executeSql()

2022-04-06 Thread Raymond Nijssen via QGIS-Developer


Hi Alessandro,

Thanks for looking into this!
My QGIS-master + GDAL 3.0.4 returns the same result for that query.


But in QGIS-master, when I try:

q = 'SELECT *, edit_id FROM soilexc_edits ORDER BY edit_id'

I get:
[0, 1, PyQt5.QtCore.QDateTime(2022, 3, 1, 0, 0), 'test1', True]
[1, 2, PyQt5.QtCore.QDateTime(2022, 3, 2, 0, 0), 'test2', True]
[2, 3, PyQt5.QtCore.QDateTime(2022, 3, 3, 0, 0), 'test3', True]

I would expect:
[0, PyQt5.QtCore.QDateTime(2022, 3, 1, 0, 0), 'test1', True, 0]



The point is I'm building a plugin that should work in multiple QGIS 
versions (from 3.10), so I'm trying to write queries that will work for 
any version and that seems very hard.


For now the edit_id+0 workaround does the trick.

BTW, Another thing I bumped into is the QDateTime in the result always 
having the time 00:00. Is that some known limitation?


Kind regards,
Raymond

Re: [QGIS-Developer] Possible Contributor Meeting in April 2022

2022-03-30 Thread Raymond Nijssen via QGIS-Developer

Dear community,

Seems too short time for most people to attend a contributor meeting
this April. We counted about 10 people only, mostly from The
Netherlands. Therefore we decided to postpone again with one year, until
spring 2023.

Meanwhile we will host a "hackday" on Friday April 29, 2022. We have
capacity for 20 people so, if you are willing to gather and contribute
to the project.. run and save your spot by registering your name on the
wiki page:

Hope to see you soon!

Raymond
