Re: [QGIS-Developer] Qt WebEngine in QGIS 3.36

[Enrico Ferreguti via QGIS-Developer]

Update on this: The flatpak QGIS 3.36.3 with Qt 5.15.10 has no issues. I'll
go with this.
Thank you very much for the support.

[QGIS-Developer] Qt WebEngine in QGIS 3.36

[Enrico Ferreguti via QGIS-Developer]

Dear QGIS developers, I would need your support to update my plugins.

I read that Qt WebEngine, from QGIS

3.36.3-Maidenhead, QT 5.15.3, is available for plugins:
https://changelog.qgis.org/en/entry/2607

But on Ubuntu Jammy LTS 22.04 and a fresh QGIS 3.36.3-Maidenhead with QT
5.15.3, when I try to import from QT5:
from PyQt5.QtWebEngineWidgets import QWebEngineView, QWebEnginePage,

I get an exception:
ImportError: QtWebEngineWidgets must be imported before a QCoreApplication
instance is created

and when I do the same from python3 in bash I get no exceptions

Where Am I wrong? Is there something different to do for importing
QtWebEngineWidgets ?
Can you point me to a running example?

Thank you very much.

I agree with Vincent and Matteo and even if I understand the need of fund
bugfixing and qt6 migration I would strongly recommend to improve grants
budget as a consistent way to interact with community, furthermore I would
enlarge core developers audience in any way with targeted training and
social involvement and lowering the needed technical contribution skills. I
thank you all for sharing this interesting discussion.

What about accepting requests with same CRS of feature source? Could be
this a reasonable feature request?
Anyway on REST Interface you did a great job. Thanks.

[QGIS-Developer] WFS3 API POST PUT Methods

[Enrico Ferreguti]

Hi QGIS devs,
I'm testing the API REST interface for updating a WFS3 and I verified that
the new/modified feature had to be expressed in geojson format in EPSG:4326
coordinates regardless of the SRID of the served layer. I verified the
behaviour with QGIS server 3.16 LTR and latest 3.22

Is this an issue or a feature due to compliance to OGC or RFC7946 standards?

Anyway I found this behaviour very uncomfortable because it obliges to
perform preliminarly unaccurate reprojections from javascript/python
clients.

Best regards.
Enrico Ferreguti.

Re: [QGIS-Developer] Can't get values from QgsMeshLayer

[Enrico Ferreguti]

Thanks for the quick reply Vincent, it was really the crs mismatch. I
didn't aware that for extracting values the underlying triangular mesh has
to be updated.
anyway there is a little issue in the script you provide, even the sample
point has to be transformed to MapCanvas crs
p1 = transform.trasform(QgsPointXY(1.60301, 38.38453))
In effect putting the project to the same crs of the mesh layer (4326) the
script outputs the correct values
so the above script should be the following

##
mesh=QgsMeshLayer('/your/path//20210202_211414_ICON_EU_P06_.grb2','mesh','mdal')
print("mesh is valid:",mesh.isValid())

# First, we need to build the triangular mesh used to render and access the
mesh from the layer
# QgsCoordinatesTransform is needed, here we build one with destination to
the map but could be other one
# If the layer is already render in the map, no need to do that if we want
it in the same coordinates than the map

destinationCrs=iface.mapCanvas().mapSettings().destinationCrs()
transform=QgsCoordinateTransform(mesh.crs(),destinationCrs,QgsProject.instance().transformContext())
mesh.updateTriangularMesh(transform)

p1 = transform.trasform(QgsPointXY(1.60301, 38.38453))

ds_group_index = 1

for g in mesh.datasetGroupsIndexes():
print ("MESH GROUP:", g,
mesh.datasetGroupMetadata(QgsMeshDatasetIndex(g,0)).name())

for i in range(mesh.datasetCount(QgsMeshDatasetIndex(ds_group_index,0))):
dataset = QgsMeshDatasetIndex(ds_group_index, i)
meta = mesh.datasetMetadata(dataset)
t = meta.time()
value = mesh.datasetValue(dataset, p1)
print ("VALUES P1",t,value.scalar(),value.x(),value.y())
##

[QGIS-Developer] Can't get values from QgsMeshLayer

[Enrico Ferreguti]

I'm trying to write a simple function for retrieving wind speed and
direction at a specified moment from a given grib file readable as mesh
layer the prototype script is the following:

mesh = QgsMeshLayer("[path to the attached
grib]/20210202_211414_ICON_EU_P06_.grb2","test","mdal")
#mesh = iface.activeLayer()
p1 = QgsPointXY(1.60301, 38.38453)

ds_group_index = 1

for g in mesh.datasetGroupsIndexes():
print ("MESH GROUP:", g,
mesh.datasetGroupMetadata(mesh.datasetIndexAtRelativeTime(h0,g)).name())

for i in range(mesh.dataProvider().datasetCount(ds_group_index)):
meta =
mesh.dataProvider().datasetMetadata(QgsMeshDatasetIndex(ds_group_index, i))
t = meta.time()
dataset = QgsMeshDatasetIndex(ds_group_index, i)
value = mesh.datasetValue(dataset, p1)
print ("VALUES P1",t,value.scalar(),value.x(),value.y())

When I run the script I can get dataset names from metadata but I'getting
Nan as values
I verified that the grib is loadable in mapcanvas and the sample point is
within grib extent.
I read the note in api (
https://qgis.org/api/classQgsMeshLayer.html#a76a7ec072b4acaf45c1a10f5872c4948)
"It uses previously cached and indexed triangular mesh and so if the layer
has not been rendered previously (e.g. when used in a script) it returns
NaN value" so I tried to process an already loaded mesh (decomment line 2)
without luck.

Is there anybody who can help me finding what I'm doing wrong? Thanks.

[QGIS-Developer] How to open a QGIS prococessing algorithm dialog in python?

[Enrico Ferreguti]

Hi QGIS developers,

I would like to programmatically show a processing algoritm dialog from
python. I gived a look to processing toolbox and I found that this is
possible importing and instantiating the class AlgorithmDialog
[gui/processingToolbox.py][1]

from processing.gui.AlgorithmDialog import AlgorithmDialog
from qgis.core import QgsApplication

alg =
QgsApplication.processingRegistry().algorithmById('qgis:extractbyattribute')
dlg = AlgorithmDialog(alg, False, iface.mainWindow())
dlg.show()
dlg.exec_()

This opens algorithm dialog and let me perform processing computations but
once closed the dialog window QGIS become instable and crash without any
message interacting with the user interface.

What am I doing wrong? Is there a method to do this in other way?

I just posted the question on StackExchange:
https://gis.stackexchange.com/questions/348542/open-qgis-prococessing-algorithm-dialog-with-python

Thanks in advance.
Enrico Ferreguti.

[QGIS-Developer] QWebView issues

[Enrico Ferreguti]

Hi Dev List,
I'm facing to QWebView issues after upgrading to QGIS 3.10 under Windows
(Linux seems not affected) that prevent some plugins from regular execution
(go2streetview, go2mapillary, Qgis2Threejs). I already submitted to issue
track: https://github.com/qgis/QGIS/issues/32507 , have issue reports from
other users and personally checked on my machine but  @minorua does not
confirm: https://github.com/minorua/Qgis2threejs/issues/191
so I ask if anyone could verify or suggest a fix
Thanks.
Enrico.

Re: [QGIS-Developer] Explode HStore algorithm

[Enrico Ferreguti]

You can handle hstore using dedicated maps functions in expressions:

Re: [QGIS-Developer] Boundless Web App Builder and qgis2web - QGIS grant proposal possible

[Enrico Ferreguti]

I would be interested in helping you.
I'm porting to QGIS3 a plugin (https://github.com/enricofer/gdrive_provider)
for using google spreadsheets as QGIS dataprovider and I did some test for
using WAB portions to export these layers to web:
https://github.com/enricofer/GooGIS2CSV
for example:
https://enricofer.github.io/GooGIS2CSV/converter.html?spreadsheet_id=15zmg1f36uEdHZNDOnSXrDtXPFtAYq8Ax7rw82WnB3Bo,1yPAqNQLAGBmATT8j3VQV64Xw0lEkjtirD5qsh687YgM,1WscQj2qN3vCXWhKGIQ16F4BpWgMFfaxyOcHmrWrUkAY,1Av8PtNKTyYAQ1wnkfUht1LsVOf-k6zU30HnXqsoffLs
reproject and display on Openlayers map google_drive layers edited and
styles in QGIS.
It would be great see this on Qgis2Web.

Regards. Enrico.

Thanks Denis. Very clear python docs!
Just out of curiosity, I read somewhere why QgisInterface has 'Qgis' prefix
and all other classes have 'Qgs' but I totally forget the reason There
was something about Gary Sherman

[QGIS-Developer] API freeze

[Enrico Ferreguti]

Hi all, In github wiki I read that: " QGIS 3 has entered feature freeze.
It's, therefore, time to port your plugin. But be aware that the *API is
not freezed yet*. "

Me and many other plugin developers are partecipating to QGIS3 migration
effort.
I'm handling issues notifications related to API break, (
https://github.com/enricofer/go2streetview/issues/35,
https://github.com/enricofer/go2mapillary/issues/9) and I would know when
API will be stable? Should we expect breaks till the final release?

I understand that core devs are working hard to make next release more
stable, I would only know how to schedule my time contribution.

Many Thanks.

Re: [QGIS-Developer] QgsLayout.itemById returns wrong object

[Enrico Ferreguti]

I'm testing the code under QGIS3, but I fear that
isinstance(item, item_class), in my case: isinstance(item,
QgsLayoutItemPicture)
returns always false because item is of QgsLayoutItem generic class

Nyall's workaround works for me without exceptions:

from qgis.core import QgsProject, QgsLayoutItemPicture
import sip
myLayout = QgsProject.instance().layoutManager().layoutByName('test')
myLayoutPicture =
sip.cast(myLayout.itemById("picture"),QgsLayoutItemPicture)
myLayoutPicture.setPicturePath("path to an image")

[QGIS-Developer] QgsLayout.itemById returns wrong object

[Enrico Ferreguti]

I'm trying to programmatically set a QgsLayoutPicture content in QGIS3.0:

1) I create a new print composition and I name it 'test'
2) I create a picture frame in the composition and I call it 'picture'
3) I run the following code:

from qgis.core import QgsProject
myLayout = QgsProject.instance().layoutManager().layoutByName('test')
myLayoutPicture = myLayout.itemById("picture")
myLayoutPicture.setPicturePath("path to an image")

and I get the following Exception:
AttributeError: 'QgsLayoutItem' object has no attribute 'setPicturePath'

If I inspect myLayoutPicture object I found it is a
qgis._core.QgsLayoutItem not a QgsLayoutPicture

Is this a correct behaviour or is it an issue? How can I get the right
Layout object?

Regards.

Re: [QGIS-Developer] Plugin for both QGIS2 and QGIS3

[Enrico Ferreguti]

I both migrate plugin keeping qgis2 compatibility (
https://github.com/enricofer/attributepainter) or branching to qgis3 only (
https://github.com/enricofer/go2streetview)
Having to carry out 3 migrations in one: python2 to python3, QT4 to QT5,
PyQt2 to PyQt3,  in my experience I strongly suggest you to branch to Qgis3
only, leaving the qgis2 compatibility to simpler plugins.
You will get a more readable and efficient code, and you'll get the
opportunity to understand and exploit the api breaks benefits.

Re: [QGIS-Developer] Convert from mapunits to pixels

[Enrico Ferreguti]

It's a QGIS3 plugin, I have not yet understood how to exclude QGIS2 from
plugin search.

Hi Tom, I'm not sure to understand your problem, I point you to the
function that downloads vector tiles from mapillary doing that conversion:

Re: [QGIS-Developer] can't load plugins with QGIS custom widgets in windows

[Enrico Ferreguti]

Hi Loïc,
I have no luck with your fix. I'm getting the same exception.
The uic module doesn't recognize the property
QgsMapLayerProxyModel::RasterLayer
of the custom widget as valid. I tried to remove the entire property
section from .ui file and set it programmatically during the dialog
__init__ with
self.RasterLayer.setFilters(QgsMapLayerProxyModel.RasterLayer)
after setupUi but the widget does not load available layers...

Thanks anyway.

[QGIS-Developer] can't load plugins with QGIS custom widgets in windows

[Enrico Ferreguti]

I'm getting the following exception:

AttributeError: unknown enum QgsMapLayerProxyModel::RasterLayer
>

loading a plugin with QGIS custom QT designer widget in windows standalone
QGIS 2.14 ltr and 2.18.

The exception doesn't affect linux and osgeo4win installations.

I found that this was a 2015 reported issue:
https://issues.qgis.org/issues/13428
and I solve it as suggested in
https://lists.osgeo.org/pipermail/qgis-developer/2015-September/039196.html
simply copying a file in the right place.

The fix is apparently easy and considering that Qt custom widgets are
widely used I can't figure why this old issue isn't yet solved.

Is it a qgis or an osgeo4win issue? Should I reopen a ticket?

Thanks. Enrico Ferreguti.

So I should release the plugin with GPLv3 that I understand is compatible
with with plugin licencing policy ("GPLv2 or greater")
<http://blog.qgis.org/2016/05/29/licensing-requirements-for-qgis-plugins/>

The plugin is provided with a checkbox that makes aware the user about the

Do You think that GPLv3 licensing and Google Drive Terms of Service

Re: [Qgis-developer] QGIS remote control API

I never tested, but I see there is https://github.com/3liz/qgis-wps4server
a server-plugin to perform remote geoprocessing jobs.
Anyway I think this could be very handy for remote qgis-server

[Qgis-developer] QT5 signals/slots in QGIS3

[Enrico Ferreguti]

I am migrating a plugin to QGIS3 and under Windows with the latest qgis-dev
release(build 1182816) I get an error connecting to well know
QgsVectorLayer signals:

vectorlayer.committedAttributesAdded.connect(self.attributes_added)
or
vectorlayer.committedFeaturesAdded.connect(self.attributes_added)

give:

TypeError: C++ type 'QList' is not supported as a signal argument type

I give a look to PyQT5 signal/slot model and I haven't found something
different from PyQT4 so don't understand if this is a bug or a new QGIS3
signal behaviour...

Is there somewhere a raw class/methods changes list from QGIS2 to QGIS3?

Re: [Qgis-developer] Plugin [1102] AequilibraE approval notification.

[Enrico Ferreguti]

I wasn't aware to have an executable between my plugin sources.
In my case I have just removed it from the pyxform library as QgisODK
plugin does not require XForm validation and resubmit it to the repository.
But I think that if a library has an open source origin, a corresponding
licence, and is shared with a community should be normally accepted in a
qgis plugin bundle even if containing compiled binaries. We have to think
that gis is computationally intensive and a software like QGis is suited to
integrate different tools.
So I think that is not so useful for QGis users to strictly fulfil the "no
executable" policy. Protecting in this way QGis global stability we could
lose many opportunities, leaving them to proprietary systems much more
uninhibited.

Best Regards
Enrico Ferreguti

[Qgis-developer] GeoJSON issue

[Enrico Ferreguti]

I'm having a weird issue loading geojson on Qgis 2.12.3 under Ubuntu 14.04
LTS
Features are loaded with coordinates truncated as if they were integer
number. It's a big problem with WGS84 projection because a point like
E11.3455668 N45.4566996 is inserted as E11 N45
The issue appears even loading geojson from URL so it can be easily
reproduced:
For example inserting GeoJSON from with:
http://api.mapillary.com/v1/im/search?min-lat=45.4236627857&max-lat=45.4276518411&min-lon=11.8448906543&max-lon=11.8637224647&max-results=200&geojson=true
all features collapsed to E11 N45
The problem does not reside on source because coordinates in the provided
GeJSON are right.
The strange is that other testing systems do not appear affected ( qgis
2.12.2 under windows 32bit and qgis 2.10 under LUbuntu 14.04 LTS).

Is there Anyone who confims the issue? Should I open a ticket?

Regards.

[Qgis-developer] Fwd: QgsExpression class can't evaluate not registered Layers

[Enrico Ferreguti]

Hi Nathan,

you can have a look to a the new version of changeDataSource plugin I was
releasing: https://github.com/enricofer/changeDataSource
Once installed, clicking on toolbutton [image: Immagine incorporata 3] is
possible to change the datasources of loaded layers
Expressions are used to massively replace datasources strings using a dummy
memory layer build up on the fly (called layerTable) that contains loaded
layers parameters.
This layer appears in legend when dialog is shown to allow expression
performing, because if layerTable layer is not charged in Registry its
fields are not listed in Expression Dialog under "Fields and Values"

[image: Immagine incorporata 4]

Expression is evaluated at row 541 in changeDataSource.py

Thanks.

[Qgis-developer] QgsExpression class can't evaluate not registered Layers

[Enrico Ferreguti]

Hi, I noticed that QgsExpression class can't evaluate layers that are not
loaded in QgsMapLayerRegistry.
This is a bit annoying because expressions could be evaluated against a
temporary datasource or external data without necessary show it to the
user. (an alternative question could be: Is it possible to hide a legend
item?)
Should I submit a feature request for this?

Enrico Ferreguti.

[Qgis-developer] R: QgsBrowserDockWidget

[Enrico Ferreguti]

I didn't think it was so simple.
You take a QTreeView For example from QDesigner then you assign QgsTreeModel as 
view model, you add some trivial interaction logic and you get Your personal 
qgis browser.
That's all. Great Qgis!

Regards.
Enrico Ferreguti.

Hi Enrico,

I found other base classes in app that can be simply ported to library
without or with not so much code rewrite (e.g the identify widget).
I don't know about this class (seems there is only a qgisapp reference
using it's singleton), but usually is due the fact that it is a work
and developer would have time to do this.

in my opinion, feel free to do pull request... and hopefully adding test ;)

Hi Luigi, 
Contributing to core development is for now far from my skills. I was looking 
for a convenient way to browse available datasouces without to deal with qt gui 
engineering that is sometimes makes feel like reinventing the wheel. Thanks 
anyway.

Hi all.

I notice that QgsBrowserDockWidget class is not included in python bindings.
It would be great to have access to browser panel items from plugins.
Is it intentional or an issue?

[Qgis-developer] row conditional formatting does not update

[Enrico Ferreguti]

Thanks for conditional formatting! It's a really great new feature!
But I noticed that with row formatting enable, cell aspect does not update
as the value changes. You have to re-apply rules to update the table.
Is it the normal behaviour or an Issue?

Re: [Qgis-developer] OpenlayersPlugin QGIS

[Enrico Ferreguti]

starting by saying that I never experienced problems with Openlayers plugin
behind proxy, anyway I resolved all my proxy issues (user, passwords,
subnet exclusions ...) using Qgis own network manager instead of creating a
new one so you can try to remove the lines from 48 to 51 of
openlayers_layer.py file and replace the row 52:
self.setNetworkAccessManager(self.__manager)
with the following:
self.setNetworkAccessManager(QgsNetworkAccessManager.instance())
I just try and it goes but I don't know if it resolvs your issue.

Enrico Ferreguti

[Qgis-developer] R: [Qgis-user] Re : view only current feature inatlas maps

[Enrico Ferreguti]

I agree with Michaël. I do not mean to modify styles from composer. Checking 
the option in composer should not influence map styles. It should only control 
feature visibility on atlas map item.

Another proposal : in the gui for rule base rendering, we could add a new 
column in the rules tables, name "Activate only for atlas", which will allow 
the user to toggle each rule. If the checkbox is checked, the rule is used only 
in atlas.
This way the user can tune more easily, in the context of QGIS vector layer 
properties. 
I do not like having checkbox in the composer, since the composer is not always 
opened and visible.

Hi,
i don't know if there is a work around but a big +1 for your UI proposal.

Objet : [Qgis-developer] view only current feature in atlas maps
Date : ven., sept. 11, 2015 10:49

Hi list,
when I need to isolate the current atlas feature in map views I currently 
enable the rule based feature style and I set the rule to "$atlasfeatureid = 
$id" following this tutorial: 
http://nathanw.net/2013/12/02/waiting-for-qgis-2-2-highlighting-current-atlas-feature/
I'm wondering if there is an easier method, accessible for the common gis user, 
to do this avoiding expressions and complex styling methods, and if it's 
possible to control this behaviour directly from "controlled by altas" slot in 
map item properties tab as from the attached sample image.

Re: [Qgis-developer] Change the query of a query layer (postgis)

[Enrico Ferreguti]

Hi Olivier,
datasource changing is a feature that I really miss and wait from longtime.
Every Qgis new release I checked without success if the properties
datasource string is editable. I recently found the hack you report (
https://geogear.wordpress.som/2015/05/15/changing-qgis-layer-datasource-with-python/)
that I verify to be working up to Wien 2.8.2. Till 2.9 the code crash qgis.
Reading your post I realized that a new QgsVectorLayer method has appeared:
setDatasource. Wow! Perhaps the waiting is going to be over

Regards,

Enrico Ferreguti.
