[QGIS-Developer] lack of conflation tools

[PIERRE Sylvain via QGIS-Developer]

Hi devs and  qgis power users,

After investigating I can arg that there's a lack of conflation tools in QGIS 
like such existing for Esri  :

https://proceedings.esri.com/library/userconf/proc17/tech-workshops/tw_513-105.pdf


Is there some plan or something I miss for doing such task in QGIS ?

Thanks

[QGIS-Developer] wrong VRT layer extent

[PIERRE Sylvain via QGIS-Developer]

Hi,

Trying to simply export VRT layer , getting a wrong extent and exporting only 
extent of first raster part of VRT with this code :

  list_dalles = []

features = layer.selectedFeatures()
for f in features:
file_name = f['NOM_DALLE']+'.tif'
dir_name = f['repertoire']
full_file_name = os.path.join( dir_name, file_name)

if os.path.isfile(full_file_name):
list_dalles.append(full_file_name)

parameters = { 'ADD_ALPHA' : False,
'ASSIGN_CRS' : None,
'EXTRA' : '',
'INPUT' : list_dalles,
'OUTPUT' : outVRTfile,
'PROJ_DIFFERENCE' : False,
'RESAMPLING' : 0,
'RESOLUTION' : 0,
'SEPARATE' : False,
'SRC_NODATA' : '' }

#processing.runAndLoadResults("gdal:buildvirtualraster", parameters)
processing.run("gdal:buildvirtualraster", parameters)

vrtLayer = QgsRasterLayer(full_file_name, "bidon")

QgsProject.instance().addMapLayer(vrtLayer, True)

file_writer = QgsRasterFileWriter(outfile)
provider = vrtLayer.dataProvider()
pipe = QgsRasterPipe()

if not pipe.set(provider.clone()):
print ("Cannot set pipe provider")

print(str(provider.extent()))
file_writer.writeRaster(
pipe,
provider.xSize(),
provider.ySize(),
provider.extent(),
provider.crs())

I don't find anything about that, any idea ?

Thanks

Bonjour Sylvain,

J'espère que vous allez bien.


If you want to append features from a source layer to another layer that 
already exists in a GPKG file, you can do this:

-
options = QgsVectorFileWriter.SaveVectorOptions()
options.driverName = "GPKG"
options.layerName = "my_existing_layer_name"  # Write here the existing layer 
name in the GPKG
options.actionOnExistingFile = QgsVectorFileWriter.AppendToLayerNoNewFields
options.onlySelectedFeatures = True

path = "/tmp/existing_gpkg_file_path.gpkg"
layer = QgsVectorLayer("/tmp/my_source_layer.shp", "my source layer name", 
"ogr")

result = QgsVectorFileWriter.writeAsVectorFormatV3(
layer,
path,  # Existing GPKG file path
layer.transformContext(),
options)
-


If on the contrary, you want to append a whole layer (with its own field 
structure, crs, etc.) to an existing GPKG database, you can follow this 
solution:

https://gis.stackexchange.com/a/417950


As you can see, the key is to define the options.actionOnExistingFile property, 
whose possible values are well documented here:

https://api.qgis.org/api/3.28/classQgsVectorFileWriter.html#afda86eff21ac1da7dc42cbdde424acb1


Note: SInce we're using writeAsVectorFormatV3(), you need at least QGIS v3.20 
for this solution to work.


Regards,

Germán

Here is my full python init form dialog function:

Can you provide a little more code?

And more info where exactly it is called (in the startup.py or in some form 
init code?

Is 'dialog' available in the code part in which you try to close it?

Richard Duivenvoorde

[QGIS-Developer] PyQgis Standalone app from 3.4 to 3.16

[PIERRE Sylvain via QGIS-Developer]

Hi devs,

I'm porting a PyQgis standalone app from 3.4 to 3.16 api.
I get an error with the new 3.16 app
QSqlDatabase: QPSQL driver not loaded
QSqlDatabase: available drivers: 

The most visible change I noticed is python 3.7 to 3.9. Is there any impact on 
PyQt5 bindings ?  With python 3.7 there was a C:\Program Files\QGIS 
3.4\apps\Python37\sip directory which is missing with python 3.9.

Here is my app env variables
os.environ['QT_QPA_PLATFORM_PLUGIN_PATH'] = r'C:\Program Files\QGIS 
3.16.16\apps\Qt5\plugins'
os.environ['PATH'] += r';C:\Program Files\QGIS 3.16.16\apps\qgis-ltr;C:\Program

Did I miss something ?

Hi Pierre,

Not sure if you are aware that recent QGIS releases also have very good 
"default" value support without having to use Python. You can simply set 
default values with QGIS expressions. No need for Python code (unless you do 
something really special).

You can even set date values dependent on other widgets without having to use 
Python scripting - and do updates whenever something changes on the record, 
without having to fall back to Python scripting.

Just wanted to make sure you are aware of this alternative mechanism. There 
might still be good reasons for using Python scripting though - but theses 
cases are now rarer.

Greetings,

Andreas

It's probably that you have to find a QDateTimeEdit rather than the Qt native

Not 100% sure this is the issue though, but it won't hurt.

Hi,

Which module is 'date.today()' from, not Qt is it?

You probably have to use the QDatetime: 
https://doc.qt.io/qt-5/qdatetime.html#currentDateTime

>>> QDateTime.currentDateTime()
PyQt5.QtCore.QDateTime(2022, 3, 25, 8, 44, 19, 963)

And set THAT with the widget?

See: https://doc.qt.io/qt-5/qdatetimeedit.html#dateTime-prop

(it always a little hassle to juggle with date/time etc in Python/Qt)

Regards,

Richard Duivenvoorde

Re: [QGIS-Developer] Drag and drop form function QdateEdit Widget init

Thanks for tip Richard, but I've tried with 
today = QtCore.QDateTime.currentDateTime()
But it's not working

[QGIS-Developer] Drag and drop form function QdateEdit Widget init

[PIERRE Sylvain via QGIS-Developer]

Hi,
I build a form for a layer with drag and drop mode, and I use an init function 
to init some value for some widdget. I have no problem to do that with 
Qcombobox an QLineEdit widget :


linedit_imat = dialog.findChild(QLineEdit,"code_eqpt")
linedit_imat.setText(imatEqpt)

linedit_com = dialog.findChild(QLineEdit,"fk_commune")
linedit_com.setText(find_comtxt)

But this is not working with QDateEdit widget :
today = date.today()
control = dialog.findChild(QDateEdit,"date_insert")
control.setDateTime(today)

What is the right syntax to init the date widget ? It's impossible to debug 
init script (or may be I'm missing something...)

Thanks

[QGIS-Developer] donuts charts

[PIERRE Sylvain via QGIS-Developer]

Hi all,

Is there something already exists or planed to make a map with donuts charts 
instead of pie charts ?
I do not find anything yet.
Il I look at plotly, it seems realy simple : 
https://support.sisense.com/kb/en/article/donut-charts-%E2%80%94-plotly
Do you think it should be difficult to manage a new « hole » parameter in Qgis 
charts ?

Thanks
