Yes, I did this in my startup script:

import pyplugin_installer

repos = pyplugin_installer.installer_data.Repositories

def trusted_url_params(self):
"""Add trusted parameter to be included in every request"""
v = str(QGis.QGIS_VERSION_INT)
return "?qgis={}.{}&trusted=true".format(int(v[0]), int(v[1:3]))

repos.urlParams = trusted_url_params

and while trusted=true then appeared in the plugin manager interface,
it did not filter the repository list. So looks like that parameter wasn't
supported after all.

Thanks Luigi,

If I do:

import pyplugin_installer

pyplugin_installer.installer_data.officialRepo = (
QCoreApplication.translate(
'QgsPluginInstaller',
'QGIS Official Plugin Repository'),
new_url,
deprecated_url,
)

and also:

QSettings().setValue('Qgis/plugin-repos/QGIS Official Plugin Repository/url', 
new_url)

in my startup script then the official repository is successfully
replaced by our internal repository. Great!

> btw If you find useful an enhancement, please file a PR with you

If I submitted a PR that added a filter for trusted plugins similar to
the filters for experimental and deprecated plugins, could that only
be added to QGIS 3.2 (as a new feature)? Not 2.18?

Cheers
Daniel

[QGIS-Developer] Mitigating security risks of the Official Plugin Repository

[Daniel Silk]

Hi all

I am currently involved in rolling QGIS 2.18 out in a corporate environment. 
The security risk of a user installing a malicious plugin from the Official 
Plugin Repository has come up.

While we can ensure our corporate plugin repository is immediately visible to 
all corporate users via a startup.py script, it appears that we:
- cannot remove the Official Plugin Repository from the repository list (due to 
https://github.com/qgis/QGIS/blob/release-2_18/python/pyplugin_installer/installer_data.py#L316-L326)
- cannot disable the Official Plugin Repository via Python API (and the user 
would just be able to enable via the Plugin Manager interface anyway)
- cannot set the Plugin Manager interface to only show trusted plugins
- cannot set the url parameters to include trusted=true as the url params are 
hardcoded: 
https://github.com/qgis/QGIS/blob/release-2_18/python/pyplugin_installer/installer_data.py#L228

So is there any other way to remove the Official Plugin Repository or limit the 
plugins that we allow users to view and install?

Thanks
Daniel

Re: [Qgis-developer] raster to postgresql/postgis GUI plugin

Maybe... I mean, for now, as it is a "standalone" plugin which does not
connect to the database, it probably is a good idea.
But, if added as a processing sub-plugin, will it be able to find the db
connection selected either in the "sources-browser" tree or in
db-manager? That functionality will be needed when the raster2pgsql
output is sent directly to the db connection.

Sure, I just grabbed the first option that appeared on the python
manual. It would also be nice to show the progress, but apparently
raster2pgsql doesn't output some kind of feedback which could be used in
that way.

Re: [Qgis-developer] raster to postgresql/postgis GUI plugin

[Daniel Vicente Lühr Sierra]

Hi Paolo,

I will definitely try merging it with dbmanager at some point, but I 
think some testing as a standalone plugin will not hurt.


Also, I am just a basic git user and as dbmanager is part of QGIS, I 
don't know how to fork just the plugin code and not the whole QGIS 
repository, for developing, testing and then submitting the pull-resquest.


Thanks

Thanks for your plugin, much appreciate. I'm pretty sure it will be far
more useful if incorporated in Plugin Manager, so the behaviour would
mimic the one for vectors: could you please rework it as a patch of it?
Submitting a pull request through GitHub is quite easy.
All the best.

[Qgis-developer] raster to postgresql/postgis GUI plugin

[Daniel Vicente Lühr Sierra]

Hi,

I was unable to find a way to upload raster data to a PostGis DB from QGIS.

I was aware of the raster2pgsql tool, but for the user-cases in my
projects, it is not an acceptable alternative (users do not have cli or
programming skills).

So, to temporally workaround this shortcoming, I decided to implement a
QGIS plugin to act as a GUI to the raster2pgsql program.

I have a working prototype available at
https://bitbucket.org/danielluehr/rastertopgsql/overview

Please, note that it is the result of just a couple of days' work, and
it is my first attempt at writing a QGIS plugin. It is just a
quick&dirty implementation that is far from being complete or foolproof.

My goal was to call the raster2pgsql program and pipe the output to the
DB directly, but I still don't know what is the best approach to send
data to an established connection (or maybe open one at that moment).
So, currently, the plugin just calls raster2pgsql on a file (with user
specified options from the plugin GUI) and saves the results to a SQL
file to be "manually" injected on the database (using some DB-manager
GUI, for instance).

I think a good alternative would be to incorporate it as a sub-plugin in
the dbmanager plugin.

I have briefly tested the plugin only against QGIS 2.8.9 and
PostGIS/raster2pgsql 2.1.4 which is my target environment.

Any comments, suggestions, contributions are welcome.

I used plugin-builder and I think it has the minimal requirements to be
uploaded to the plugin repository (at least, as an experimental plugin),
but I would prefer to have some feedback before uploading it there.

Regards

Re: [Qgis-developer] Compliation issues of sources using "make" on Linux Ubuntu

[Florin-Daniel Cioloboc]

Thank you, Hugo!

That was a good tip, as I was checking the files I enabled the "allow
executing file as program". Whether that was the magic trick, I am unsure
but in any case now it's working. Same goes for the import qgis.core in the
Ubuntu terminal, no more import errors.

Hopefully, I can actually start to work on my plugin.

Best regards

Re: [Qgis-developer] Compliation issues of sources using "make" on Linux Ubuntu

[Florin-Daniel Cioloboc]

Thanks for the reply Alessandro,

Already done that. It still doesn't work yet, however I got the idea to
source it: source scripts/run-env-linux.sh /usr/bin/qgis-2.2/ and it worked
up, at least that command.

Unfortunately, when running make test command it get the same permission
error so at the moment I'm trying to set it using chmod but it doesn't seem
to be working.

[Qgis-developer] Compliation issues of sources using "make" on Linux Ubuntu

[Florin-Daniel Cioloboc]

Hello everyone,

I am getting a rather strange message after using the make command, which
is preventing me from compiling my sources for a plugin. As a result, the
plugin doesn't show up in QGIS.

Message:

Had an earlier issue but it was partly solved by installing PyQT4. I don't
really understand what's wrong.

I typed in prompt: *make test* and got:

[Qgis-developer] How to set the PyQGIS environnement on Windows properly?

[Florin-Daniel Cioloboc]

Hello everyone,

I'm having problems with a specific error, which is pretty common from what
I can see but can't seem to find a solution.

When I try to import the qgis module the following error occurs:

ImportError: No module named 'qgis'

So far this is the guide  I'm using
and here's the settings for the .cmd, I'm assuming it has something to do
with this:

[Qgis-developer] Attribute names and Strings are not displayed correctly

[Daniel Lincke]

Hi,

I guess this is not a bug but some problem with external libraries. In 
my qgis (using Ubuntu 14.10) and have the problem since a few weeks. I 
don't know when it started exactly,but I guess it was some update.


Whenever I look at the attribute table or at the attribute dialog for a 
shape, the attribute names are shown as _1,_2,_3, ... In the attributes, 
Strings are generally displayed as "NULL". Numbers are fine.


Since the Problem occurs, I have reinstalled qgis several times and also 
tried out several versions (2.2,2.6,2.8) but nothing changed.


In the message window, I found one warning by python:

warning:/usr/lib/python2.7/dist-packages/PyQt4/uic/uiparser.py:890: 
PendingDeprecationWarning: This method will be removed in future 
versions. Use 'elem.iter()' or 'list(elem.iter())' instead.

You just need to enable the checkbox in the "General" options and restart

Hi,

For server-side scripting, I would suggest you to check out the new

master).

At the moment the documentation is still rare (I'm slowly working to
improve it).

By now you can start from here:

I found some documentation [1,2,3,4,5], but did not achive to install

found any API documentation. Can somebody give me a hint where to find 
some more documentation? I am also interested in book recommondations.

I imagine that feed posts can be equiped with custom tags and that
qgis.org can filter feeds by tags. Maybe the authors in question want to
support the noncommercial character of the qgis.org website through
tagging advertisements in their feeds as advertisements. QGIS as a
project would be a good identity to propose a standardized tag for this,
let's say "advertisement". :) I don't know about how many authors we
talk, but maybe someone could ask them all individually and that already
solves the issue.

Re: [Qgis-developer] error starting qgis (built from source)

[Daniel Scholten]

Installing python-gdal solved the issue for me.

One could check if the building guide
http://htmlpreview.github.io/?https://raw.github.com/qgis/QGIS/master/doc/INSTALL.html#toc6
should be updated, i.e. python-gdal is added to the build dependencies.
I use Linux Mint so I don't know if it's exactly the same with Ubuntu.

Re: [Qgis-developer] error after building from source

[Daniel Scholten]

Thanks Matthias, removing the system installation and setting
LD_LIBRARY_PATH solved the issue. But now I have the already known problem:

During start of QGIS I get a Python error "Couldn't load plugin
'processing' [...]" and after a message "Unable to load GdalTools
plugin. The required "osgeo [python-gdal]" module is missing.". However,
QGIS starts and in the plugin manager with GdalTools everything seems to
be ok, whereas processing plugin is marked broken and the reinstall
button is disabled.

Any suggestions what to do? Daniel

[Qgis-developer] cannot run/ error after building from source

After building from source (qgis 2.3 checked out yesterday), following
http://htmlpreview.github.io/?https://raw.github.com/qgis/QGIS/master/doc/INSTALL.html#toc3
I try to start qgis from comand line, but on comand line I get
./qgis: symbol lookup error: ./qgis: undefined symbol:

This happens with a local build/ installation, while there is another
system wide installation of qgis. I use Linux Mint 13.

I first installed psycopg2, matplotlib, pyparsing, qscintilla2
and numpy, which did not solve the problem. Then I installed

Re: [Qgis-developer] New QGis project, application : version is empty and wms layer invalid

[Daniel]

I don't know if you should receive "2.0" as output of applicationVersion()
method.

It's because setApplicationVersion() and setApplicationName() are called
from src/core/main.cpp (QGIS code).

The class QgsApplication don't call setter methods, so I don't know what
are the supposed behavior when I call these methods.

It works for me

QString uri= "url=
http://wms.jpl.nasa.gov/wms.cgi&crs=EPSG:4326&format=image/jpeg&layers=global_mosaic&styles=pseudo
";
qDebug() << "uri" << uri;
QgsRasterLayer *rlayer = new QgsRasterLayer(uri, "layer_name", "wms",
false);
qDebug() << rlayer->isValid();


Hope it helps you

Re: [Qgis-developer] Python: Select features that touch other features

[Daniel]

Don't forgot to instantiate inFeatA e inFeatB

inFeatA = QgsFeature()
inFeatB = QgsFeature()


After vprovider.getFeatures() maybe you need to tests if inFeatB has a
valid geometry and if geometry touches the current selected one, something
like this:

geomB = QgsGeometry( inFeatB.geometry() )

if geomB.touches(geomA):
   # do something


http://www.qgis.org/api/classQgsGeometry.html#a6f4183fe331cc77ba3683c9d0d9c7181
[touches method]
http://www.qgis.org/api/classQgsVectorLayer.html#a33968fa939503a9e3873c88e5f0ea439
[selectedFeaturesIds]


PS: Sorry for the noise, but I sent the previous email without conclude it.
This completes the previous one.

Hope it helps

Re: [Qgis-developer] Python: Select features that touch other features

[Daniel]

Hi Andreas,

First create a spatial index over layer features (I got this code from
ftools_utils.py)

# Convinience function to create a spatial index for input
QgsVectorDataProvider
def createIndex( provider ):
feat = QgsFeature()
index = QgsSpatialIndex()
fit = provider.getFeatures()
while fit.nextFeature( feat ):
index.insertFeature( feat )
return index

Let's suppose that you have a vector layer "vlayer"



get the selected features:

# vector data provider
vprovider = vlayer.dataProvider()

# spatial index
index = createIndex(vprovider)

# selected features
selection = vlayer.selectedFeaturesIds()


for inFeatA in selection:
geomA = QgsGeometry( inFeatA.geometry() )
intersects = index.intersects( geomA.boundingBox() )
for feat_id in intersects:
# probably you want to discard some intersected feature that has in
selection so...
if feat_id in selection:
 continue
vprovider.getFeatures( QgsFeatureRequest().setFilterFid( int( id )
) ).nextFeature( inFeatB )

Re: [Qgis-developer] Python: Union selected polygons in a layer

[Daniel]

Try the QgsGeometry::combine() method.

http://www.qgis.org/api/classQgsGeometry.html#a63244d3435cc99794b82a6cbd0af0eb5

Quoting class doc

*Note:*this operation is not called union since its a reserved word in C++.

'System' =>  string that represents the file
encoding
vlayer.crs()  =>  vector layer crs
'SQLite'   =>  provider name
False  =>  export onlySelected?
error_msg=>  if there is any error message will be
put in that variable (if user don't care about error handling, set to None)
[ "SPATIALITE=YES" , ]   =>  database options. (here is the trick)



Also, there is a class
http://www.qgis.org/api/classQgsVectorLayerImport.html

But, I didn't have success in create an empty database using the
QgsVectorLayerImport. I think that class (QgsVectorLayerImport) expects a
created spatialite database.

[Qgis-developer] Creating a spatialite layer in a python plugin

[Daniel]

Is it possible to create a spatialite layer using python bindings?

I compiled qgis version 1.8 from source on Ubuntu 12.04

GDAL 1.9.2
Spatialite 3.0.0~beta20110817-3

I enable PYSPATIALITE from ccmake menu.

>From plugin if i call the method:

QgsVectorFileWriter.supportedFiltersAndFormats()

I have the following output, where there is not SpatiaLite format available.

GeoJSON [OGR] (*.geojson *.GEOJSON)

[Qgis-developer] Bug tracking

[Daniel]

Hi devs,

I am pretty new in QGis and very interested in help to decrease the number
of opened issues on bug tracking system.

Currently QGis issues has the following statistics:

Bugs

31 opened bugs with Blocker priority
37 opened bugs with High priority
661 opened bugs with Normal priority
243 opened bugs with Low priority

Features

1 opened features requests with Blocker priority
13 opened features requests with High priority
394 opened features requests with Normal priority
310 opened features requests with Low priority

Because the high number of opened issues it's hard to a beginner choose the
"right issues" (bugs/features) that really need atention.

I am skilled in C, C++ and Python and ready to try to contribute with QGis
community.


I look forward to hearing from you, the "right directions" that I should go
to.

[Qgis-developer] PyQGIS - How to create "Outline: Simple Line" layer?

[Gilbert, Daniel R.]

Hello All,

 

First off I'm quite the newbie when it comes to developing PyQGIS
plugins so hopefully this post makes sense...

 

I'm creating a vector layer using the memory provider.  Layer consists
of polygons and everything is working great.  

 

I'm now attempting to tailor the appearance of the symbols.  Following
the advice in this post
(http://lists.osgeo.org/pipermail/qgis-developer/2011-April/013772.html)
I successfully created just an outline (i.e. no fill):

 

props = { 'color_border' : '255,0,0,255', 'style' : 'no',
'style_border' : 'solid' }

s = QgsFillSymbolV2.createSimple(props)

vl.setRendererV2( QgsSingleSymbolRendererV2( s ) )

 

This is close to what I'd like but I notice that when selecting features
the selected features become filled which is not what I'd like.  

 

Manually adjusting the properties via the "Symbol properties" dialog I
discovered that by selecting "Outline: Simple line" from the "Symbol
layer type" pulldown provides the functionality I desire.  When
selecting features the color of the outline changes while remaining
un-filled.  Looking at the resulting entry in symbology-ng-style.xml
shows the following:

 



  

















  



 

I haven't had any luck in figuring out how to get the proper combination
of type="fill" while using "SimpleLine".  I also noticed that if I
follow the example in the PyQGIS Cookbook to display the complete list
of types for a QgsSymbolV2.Fill none of the "Outline: " types from
the dialog pulldown are listed:

 

 myRegistry = QgsSymbolLayerV2Registry.instance()

 for item in myRegistry.symbolLayersForType(QgsSymbolV2.Fill):

 ... print item

 

 CentroidFill

 LinePatternFill

 PointPatternFill

 SVGFill

 SimpleFill

 

Any advice on how to replicate the "Outline: Simple line" symbology will
be greatly appreciated!

 

Thanks,

[Qgis-developer] Display raster layer on own Map Canvas

[Daniel Klich]

Hello,

I am new to python and the QGIS API and writing a plugin in python to 
simulate/model insect dispersal.


I am using .ui files and Qt Designer. And i placed a QWidget on the form 
and promote it to a new class: set QgsMapCanvas as class name and set 
qgis.gui as header file.


I load a raster layer, set canvas color and so on. But the layer only 
displays if i use QgsMapLayerRegistry.instance().addMapLayer(self.layer).
Without these code line my plugin only displays the rubber band, but not 
the raster layer. But if i use ...addMapLayer() it also loads the layer 
in QGIS. I want to have a behaviour like in the GDAL - Georeferenzierung 
plugin. There you could add a raster layer and the plugin displays it 
only in the plugin window, not in the QGIS MainWindow.


Here is the method code:

def addRasterLayer(self):
fileName = "NE2_50M_SR.tif"
fileInfo = QFileInfo(fileName)
baseName = fileInfo.baseName()
self.layer = QgsRasterLayer(fileName, baseName)
if not self.layer.isValid():
  #error

#only with this line of code the raster layer will be displayed:
QgsMapLayerRegistry.instance().addMapLayer(self.layer)

self.canvas = self.dlg.ui.mapCanvasWidget

self.canvas.setCanvasColor(Qt.white)
self.canvas.setExtent(self.layer.extent())
self.canvas.setLayerSet( [ QgsMapCanvasLayer(self.layer) ] )

r = QgsRubberBand(self.dlg.ui.mapCanvasWidget, True)
points = [ [ QgsPoint(-10,-10), QgsPoint(0,10), 
QgsPoint(10,-10) ] ]

r.setToGeometry(QgsGeometry.fromPolygon(points), None)

self.canvas.setCurrentLayer (self.layer)
self.canvas.setVisible(True);
self.canvas.refresh()




best regards,

Daniel

Re: [Qgis-developer] [Qgis-user] Cast your vote: Default icon theme for QGIS 2.0

[Daniel Lee]

What if the add layer buttons were unified - one button that would then
give you the option of adding a shapefile, database table, directory, GRASS
map, etc.? That could consolidate and eliminate a lot of the confusion.

Re: [Qgis-developer] QGIS allocation error after upgrade to 1.8.0

[Daniel Lee]

Hi there,

Since I'm using the binary from the repository, I wasn't sure what exactly
I should wipe out - I don't have anything in /usr/local/lib/ except for a
python folder. Instead, I deinstalled QGIS completely using my package
manager. As far as I understand it, that should wipe out my system pckages,
wherever they are, and that without deleting my plugins. I tried that but
got the same problem again. Afterwards, I deleted the .qgis folder in my
home directory, but that didn't change anything either. Perhaps I've
understood you wrong? Did I do that right?

Thanks,
Daniel

Re: [Qgis-developer] [Qgis-user] Cast your vote: Default icon theme for QGIS 2.0

[Daniel Lee]

Hi there,

I also think the GRASS theme is great, although I have to say that I'm a
long-time GRASS user. I've often heard complaints about QGIS' icon set,
especially in Windows - people feel that it looks a bit unserious, although
I don't see it that way. However, I do see great advantages in
consolidating the use of FOSS GIS to these to main overarching packages -
it's great to have lots of products but we're a specialized, rather small
community and it's good when people don't invest their time in reinventing
the wheel. In that sense, I would support style unification across QGIS and
GRASS - it would make it easier to jump back and forth and perhaps
encourage the use of the GRASS plugin more.

Best,
Daniel

[Qgis-developer] QGIS allocation error after upgrade to 1.8.0

[Daniel Lee]

Dear list,

As this is my first post to this list, first of all hello ;)

I'm really excited about the new version of QGIS. Working with OpenSUSE
12.1 64-bit, I upgraded from the Geo repository to 1.8.0. Now, however,
QGIS won't start. On the CL I get the following error:

qgis
Warning: loading of qgis translation failed
[/usr/share/qgis/i18n//qgis_en_US]
Warning: loading of qt translation failed
[/usr/share/qt4/translations/qt_en_US]
qgis: siplib.c:10965: sipEnumType_alloc: Assertion
`(((currentType)->td_flags & 0x0007) == 0x0003)' failed.
Aborted

The splash screen pops up briefly but dies as soon as the process is
aborted. I'm also not able to find the library in question - does anybody
know of a way of fixing this? Thanks a bunch!

Daniel

Re: [Qgis-developer] installing on Citrix.

That's good to know - no difficulties at all? Just install and get going?

More fully what I'm looking at is it working with Windows Server 2003,
enterprise edition in one central office location, with those off
sight using Citrix web metaframe...

Just trying to save on those ArcGIS license costs...!

[Qgis-developer] installing on Citrix.

Hello all,

Does anyone out there have any experience with making QGIS available
to many users through a Citrix Web metaframe?

Trying to avoid doing mulitple local installs.

Anyone done anything similar or had any experience? Any common
problems/things to look out for?

Or is it not even recommended?
