Assunto: [QGIS-Developer] QField 2.0 is here

 

Dear QGIS community,

it feels like yesterday when in 2011 my inbox received the following text:
"Congratulations! Your proposal “QGIS Mobile” as submitted to “OSGeo – Open 
Source Geospatial Foundation” has been accepted for Google Summer of Code 
2011." [0]

Back then my idea was already pretty clear, create a standard version of QGIS 
that would run on android devices and later on replace the UI with something 
more mobile friendly. 
QGIS mobile was quickly born and thanks to the help of many of you by the end 
of the GSoC I had it running. 
Years and commits went by, and out of the experiment QGIS mobile a new star was 
born in 2015: QField [1]

 

What followed was pure pleasure, a fantastic community response and a huge 
uptaking of the handy fieldwork app that now counts almost half a million 
downloads and is active on roughly 150K devices monthly.

 

That is why, it is with a heartfelt thankyou that I'd like to announce the 
official availability of QField 2.0

 

If you are interested in more details on the release, here you'll find all 
information on our latest blogpost [2]

Cheers Marco

Hi,

 

The triangular mesh of mesh layer is not accessible from the python API, only 
from the C++ API.

 

So for now, not possible to access directly to the triangular mesh from Python. 
It is possible to acces ro the native from  the provider, but it will not be in 
the map coordinates if different from the data :

Hi devs,

 

I still can not get the triangular mesh from a Mesh Layer using Qgis version 
3.14.0-Pi.

The triangularMesh() attribute is present in the API documentation

https://qgis.org/api/classQgsMeshLayer.html#ae5d4ae367cfbd2abf6920d26701f0143. 

But I get an Error:

AttributeError: 'QgsMeshLayer' object has no attribute 'triangularMesh'

 

 

Is it possible to return the triangular mesh? I would like to use the 
triangular mesh for make an exact profile/cross section from the mesh using a 
polyline. The others plugins, like Crayfish and Profile tools does this profile 
using a defined interval offset, so it's accuracy depends on this interval.

 

My code below returns

AttributeError: 'QgsMeshLayer' object has no attribute 'triangularMesh'

:

proj = QgsProject.instance()

mdtLyr = proj.mapLayersByName("RA04_Surface")[0]

mdtLyr.updateTriangularMesh()

[QGIS-Developer] RES: QGIS / FreeCAD interoperability...

[Jorge Almerio]

Excited Waiting!

Hi Joel, 

 

Just a note on the QGIS-CAD-BIM "converging" roadmap everyone dreams about. 

What we see here is that many organisation up to now where using CAD software 
to manage city maps and assets management, where GIS - as a true database 
system - is far more accurate. 

We even see public entity allowing public grant only if data are transmitted in 
GIS exchange format in the end. So we see many CAD users switching to GIS - 
wether they like it or not. 

 

As a consequence, and thanks to funders who understand that free software 
allows to be active contributors, QGIS as a project is influenced a lot by CAD 
needs, at least for 2D editing.

We have some construction tools allowing to play with angles, parallels, build 
some inference temporary lines, and a lot of new shape editing tools. 

We still miss a lot of what user require, such as interactive snapping for 
instance or advanced 3D computation libraries. We also reach a point where 
geospatial standards draw a line with CAD world, for instance handling spline 
curves is at the limits. 

 

Concerning 3D and BIM buzz, we have a lot of questions from users, and 
sometimes even from national mapping agencies. And up to now, 3D plans for QGIS 
are focused on viewing datasets mainly.

We miss a lot 3D editing capabilities and FreeCAD is in my opinion the best 
candidate to provide an open source solution for this. 

 

The first bridge would be to ensure that FreeCAD deals with the main 
interchange standards to be able to edit BIM data. That would probably be 
cityGML and all the standards supported by the OGC, plus the main de facto 
standards like STL. I think we already have a challenge here to deals with 
those large datasets in reading and editing.  

 

FreeCad being able to edit those, we could already answer to the 100% open 
source BIM use case. Then an interoperability at API level between FreeCad and 
QGIS to easily open a dataset or a specific feature in QGIS<>Freecad would rock!

I would love as a user be able to view my city in 2D or 3D with QGIS, click on 
a building, open it in FreeCAD, update it, go back to QGIS, refresh, done.

 

Hope it helps

 

Best regards

Hi Joel

 

Since years ago a lot of new features can support a better integration. I did a 
rough investigation about integration and stopped due to the fact that data 
model were (or is) too different to imagine an integration.
BTW probably now is more simple (at least from the qgis point of view) thanks 
to the possibility to bridge different data models using a python data provider 
[1] [2].

I would give a try/look.

 

cheers

Hi,

 

With QGIS master you can use  
<https://qgis.org/pyqgis/master/core/QgsMeshLayer.html#qgis.core.QgsMeshLayer.updateTriangularMesh>
 updateTriangularMesh.

Before, there is a workaround that consists to just call  
<https://qgis.org/pyqgis/3.12/core/QgsMeshLayer.html#qgis.core.QgsMeshLayer.createMapRenderer>
 createMapRenderer without using the renderer.

Assunto: [QGIS-Developer] Survey on If you use QGIS what do you like the most 
about it?

 

I thought I would share with you some results of a survey I conducted earlier 
this year. There were 86 responses. Most users were using 2.x versions of the 
software, but some were using 3.x. Each person that responded may of had one or 
more items. I consolidated the similar responses so the number in front is the 
number of people that had the same basic answer.

17 - Easy to use and conduct analysis when compared with ESRI products.

1 - Editing is easier than with ArcGIS

2.- Supports excellent customization.

1 - Easier work flow for editing and creating figures.

13 - Much faster than ESRI products.

3 - Crashes less often than ArcGIS.

4 - More stable than ESRI software.

6 - Performs better than ESRI Desktop.

1 - Causes less headaches than ESRI software.

1 - Has better functionality and more useful tools than ArcGIS.

1 - More responsive than ESRI products to mouse and keyboard commands.

4 - Can do anything ArcMap can.

1 - Handles displaying big data points better than ArcGIS.

11 - Software is free.

1 - Saves the office $$$.

4 - Freedom from license restrictions.

2 - Free to download and use at home.

5 - Open source

4 - Being open source makes it easy to work with others.

2 - Conforms to OGC standards.

10 - Can easily be extended with plugins.

2 - Extensive 3rd party integration such as GRASS, TauDEM, SAGA, LASTools, and R

1 - Interesting addons not found in ArcGIS.

1 - Has great toolboxes.

10 - Works with hundreds of data formats.

2 - Produces a standards based GeoJSON file unlike ArcGIS that produces a 
modified format.

5 - Provides the very best interaction and support for PostgreSQL/PostGIS 
databases. ArcGIS does not work will with PostGIS.

2 - Better database integration.

1 - Can make PostGIS layers based on queries in QGIS.

4 - Full featured GIS application.

1 - 64 bit architecture.

2- Fast integrated GDAL/OGR library operations.

3 - Nice to have an integrated Python console.

1 - Easier to create a filter in QGIS than in ArcMap.

2 - Some QGIS tools work better than what ArcMap provides.

3 - Visualization tools are superior to ArcGIS including better rendering / 
blending capabilities.

1 - Has unique geoprocessing capabilities.

1 - Easy to write script to automate tasks.

1 - Like the persistent layer properties window, which makes infinitely more 
sense than endless pop-up clicking in Arc.

1 - Like how QGIS handles imagery stretching look-up tables.

1- Like draw pausing and cannot understand why ESRI can't get this right.

2 - Strong user community support.

1 - Can plot csv files onto a map and connect related tables of information.

I think in this case, as you do not want to close your gui, you should put the

you have a code sample in Qgis cookbook 

 , may it can help you:

QDialog.__init__(self)

self.bar = QgsMessageBar()

self.bar.setSizePolicy( QSizePolicy.Minimum, QSizePolicy.Fixed )

self.setLayout(QGridLayout())

self.layout().setContentsMargins(0, 0, 0, 0)

self.buttonbox = QDialogButtonBox(QDialogButtonBox.Ok)

self.buttonbox.accepted.connect(self.run)

[QGIS-Developer] Plugins translation

[Jorge Almerio]

Hi devs,

 

For do the plugin translations I use

 

1) Linguist from QT5

2) The command line: 

Pylupdate4 -noobsolete PluginName.pro (Is there a new version 5??)

3) and the classical code:

 

# initialize locale
locale = QSettings().value('locale/userLocale')[0:2]
locale_path = os.path.join(
self.plugin_dir,
'i18n',
'PluginName_{}.qm'.format(locale))

if os.path.exists(locale_path):
self.translator = QTranslator()
self.translator.load(locale_path)

if qVersion() > '4.3.3':

QCoreApplication.installTranslator(self.translator)

 

def tr(self, message):

return QCoreApplication.translate(QWaterPlugin.SETTINGS, message)

 

 

The problem is that the option to use self.tr('message string') is not working. 
It only works when I use QCoreApplication.translate('Escope', 'message string') 
even if a tr function defined.

 

It used to work with linguist from QT4.

 

What  Am I doing wrong? BTW Is there a new better way to translate plugins?

 

Another thing, every time I update the translations strings with Pylupdate4, I 
have to translate all my plugin forms again even without any changes, any 
help???

 

Thanks,

 

Jorge Almerio

You are right, but how to use "setEditorWidgetSetup" method?

From doc reference:
QgsVectorLayer::setEditorWidgetSetup (int index, const QgsEditorWidgetSetup &

The first argument is the field index, ok, it's easy.
But second is a QgsEditorWidgetSetup, I don't know how to create one.


My code:
pipeLyr = iface.activeLayer()
field_index = 3 #here just for test
pipeLyr.setEditorWidgetSetup(field_index,'EditText')

I got:
TypeError: QgsVectorLayer.setEditorWidgetSetup(): argument 2 has unexpected

[QGIS-Developer] Browser Panel too slow Issue

[Jorge Almerio]

Hi devs,

 

After update from Qgis 3.3.x to Qgis 3.4.1, the browser panel became too slow. 
I had to close it to use QGis.

 

Does someone realized this issue?

 

Sorry if it is not the right place for this,

 

Regards,

[QGIS-Developer] RES: Handle Bad Layers

[Jorge Almerio]

Hi devs,

About the changeDataSource plugin, there is a testing working version (it can 
be downloaded and installed from zip) for Qgis 3.x on 
https://github.com/enricofer/changeDataSource/tree/qgis3-migration-test still 
not on oficial repository.

I think this is a widely desired feature, and something I'd very much
like to see available "out of the box".

For 2.x there is a plugin "changeDataSource" which allows this
behavior. I don't think that plugin is available for 3.x yet.

[QGIS-Developer] RES: Do we really need experimental and non-experimental plugins?

[Jorge Almerio]

Hi devs,

I agree with Andreas. I think we need experimental and non-experimental flags 
to plugins as it is.
And I think that we can NOT restrict the time to be experimental. Because it 
depends on the author available time to make his plugin stable. Restrict the 
experimental plugins would reduce the number of plugins been uploaded. To mark 
as experimental is important for the users and for the authors too, because one 
can help the other to fix bugs.

Hi Borys,

Personally, I think there is a need for the differentiation of 
experimental or not experimental.

I'd like to keep it as it is.

[QGIS-Developer] Plugins translation

[Jorge Almerio]

Hi devs,

 

For do the plugin translations I use

 

1) Linguist from QT5

2) The command line: 

Pylupdate4 -noobsolete PluginName.pro (Is there a new version 5??)

3) and the classical code:

 

# initialize locale
locale = QSettings().value('locale/userLocale')[0:2]
locale_path = os.path.join(
self.plugin_dir,
'i18n',
'PluginName_{}.qm'.format(locale))

if os.path.exists(locale_path):
self.translator = QTranslator()
self.translator.load(locale_path)

if qVersion() > '4.3.3':

QCoreApplication.installTranslator(self.translator)

 

def tr(self, message):

return QCoreApplication.translate(QWaterPlugin.SETTINGS, message)

 

 

The problem is that the option to use self.tr('message string') is not working. 
It only works when I use QCoreApplication.translate('Escope', 'message string') 
even if a tr function defined.

 

It used to work with linguist from QT4.

 

What  Am I doing wrong? BTW Is there a new better way to translate plugins?

 

Another thing, every time I update the translations strings with Pylupdate4, I 
have to translate all my plugin forms again even without any changes, any 
help???

 

Thanks,

 

Jorge Almerio

QgsPluginManagerInterface is quite limited. Try this instead:

from qgis.utils import pluginMetadata
pluginMetadata('myPluginName', 'version')

I need to get the current version (in metadata.txt) of my plugin from python. I

I tried with the code below without success. Does anyone can help me?

Now I understand, selecting rows on table it selects the respective node on

Hi all,

in the vertex editor of QGIS 2.x when a line of the table id selected
the corresponding vertex is highlighted in the map.

In QGIS 3 it seems that this super useful feature is not there anymore.
I just wanted to report this ;)

Hi Jorge,

There are two possibilities, one is to use the full-blown API with
OrderBy class etc. And then there is a shorthand for this, called
QgsFeatureRequest.addOrderBy which is enough in 90% of the cases.

Short version:

  request = QgsFeatureRequest()
  request.addOrderBy('field_name')

https://qgis.org/pyqgis/master/core/Feature/QgsFeatureRequest.html#qgis.core.QgsFeatureRequest.addOrderBy

Long version:

  clause = QgsFeatureRequest.OrderByClause('field_name')
  orderBy = QgsFeatureRequest.OrderBy([clause])
  request = QgsFeatureRequest()
  request.setOrderBy(orderBy)

https://qgis.org/pyqgis/master/core/Feature/QgsFeatureRequest.html#qgis.core.QgsFeatureRequest.setOrderBy

I saw that there is a function

Simple example:

prov = lyr.dataProvider()

for feature in prov.getFeatures(QgsFeatureRequest()):

print feature.id()

and you can also, alternatively:

- set the two variables as User or System Windows Environment Variables (in
the Windows Advanced System Settings)

or

- set the two variables in QGIS through Settings -> Options | System |
Environment


The names and the values of the variables are:

variable name: OGR_SKIP
value: ODBC

variable name: PGEO_DRIVER_TEMPLATE
value: DRIVER=Microsoft Access Driver (*.mdb, *.accdb);DBQ=%s

note that there is only one percent sign in the value of
PGEO_DRIVER_TEMPLATE variable.


In both cases, you can launch QGIS normally through the Start Menu link.
