[Qgis-developer] QgsVectorLayer's attributeValueChanged SIGNAL emitted when it should not

[Germán Carrillo]

Hi All,

I'm working on a plugin and trying to connect a SLOT to
layer.attributeValueChanged SIGNAL. However, I found that such SIGNAL is
(weirdly) emitted in the following scenario:

1. Load a vector file (I've tested this with a Shapefile and an SQLITE
file) with a numeric (int or real) field, whose value for the first feature
is NULL.
2. Open the attribute table of the vector layer.
3. Start an edit session cliking on "Toggle Edit Mode" button from the
Attribute table window.

As soon as the edit session starts, the SIGNAL is emitted. Now, if I click
on the "Toggle Edit Mode" button from the Attribute table window, I have to
choose among Save, Cancel, or Close Without Saving options, even without
changing any attribute value at all. Once I choose Close Without Saving,
the layer.attributeValueChanged SIGNAL is emitted once more.

Such behavior is hampering my plugin, which will depend on the
aforementioned SIGNAL.

Is this a bug? Do you know why layer.attributeValueChanged is being emitted
in such scenario? I've noticed that sometimes a blockSignals() method is
used in QGIS source code; couldn't we use blockSignals() to avoid emitting
the SIGNAL in this case?

##
Note: I use this code snippet in the QGIS Python console to be notified
when layer.attributeValueChanged is emitted:

##
def f(fid, idx, value):
  print fid,idx,value

l = iface.activeLayer()
l.attributeValueChanged.connect( f )
##

I'm getting these messages printed (4 is the index of the numeric field
whose value for the first feature is NULL):

0 4 NULL # When I open the edit session.
0 4 NULL # When I close the edit session.

If you want to reproduce the problem, you can use a sample Shapefile from
here: http://downloads.tuxfamily.org/tuxgis/tmp/test.zip
##


Regards,

Germán

Re: [Qgis-developer] Number of arguments for processing gdalogr:warpreproject

[Tom Chadwin]

OK, Travis seems to be installing GDAL 1.10. Is that the issue? 

Get:60 http://us-central1.gce.archive.ubuntu.com/ubuntu/ trusty/universe
gdal-bin amd64 1.10.1+dfsg-5ubuntu1 [208 kB]

What version is 2.16 hoping for, specifically for calling warp via
processing? Am I right in presuming 2.x? If so, is there a PPA I can
specify? 

Thanks

Tom

Re: [Qgis-developer] Adding symbols through API needs QGIS restarts to show up

[Akbar Gumbira]

Hi Martin,

Thanks, seems to work. I read a bit the cpp code in Style Manager DIalog
that it will load the default style when showing up the dialog. So I
thought once it's written correctly to the database, it will not have this
problem. Thanks for the explanation, it's clear now what the API's are
meant to do.

Try this instead:

style = QgsStyleV2.defaultStyle()
style.addSymbol("ABC", my_symbol)

The default style is the one loaded on start and used throughout QGIS
application, so if you modify it, the changes will be immediately
visible in the GUI and will be saved automatically.

[Qgis-developer] Adding symbols through API needs QGIS restarts to show up

[Akbar Gumbira]

Hi,

I am trying to add symbols/colorramps through Python API and I have a
problem that after adding symbol/colorramps, the added symbols/colorramps
don't show up in Style Manager right away. The symbols are added in the
symbology-ng-style.db, but the added symbols show up once I restart QGIS

This is more or less the code:

style_manager = QgsStyleV2()
> style_manager.load(QgsApplication.userStyleV2Path())
> # Adding symbols here
> style_manager.addSymbol(symbol_name, symbol, True)
> # Perhaps this works, load the db again
> style_manager.load(QgsApplication.userStyleV2Path())


Is there something in the API that I could call to trigger the dialog to
show up the changes after adding the symbols?

[Qgis-developer] Bug in Redmine issue reports form?

[DelazJ]

Hi devs

Trying to report issue at
http://hub.qgis.org/projects/quantum-gis/issues/new, in the Target version
option, releases that are proposed are not only QGIS's. I have options from
plugins like BLN Exporter, Transectizer, QMarxan...
This might be a bug, I suppose.
Given that I don't know to whom I should report this

Thanks,
Harrissou

Re: [Qgis-developer] How to hide the icons over the Layer Panels ?

[DelazJ]

Hi,
menu Settings --> Customize is supposed to help you remove icons from QGIS
interface. That said, I don't know if these buttons are available in the
list nor if there's an easier way to find them (except source code). There
are some issues reports with this dialog  at
http://hub.qgis.org/projects/quantum-gis/issues (category== customisation
framework)

This problem remains now that 2.16 has been released:

Can anyone help fix this error?

the compilation with debian rules.. same error

Re: [Qgis-developer] ubuntu 2.16 packages core dump

[Matthias Kuhn]

Looks like it's compiled with -DWITH_QTWEBKIT=OFF
I don't think that should be required on Ubuntu...
But it shouldn't crash anyway, which plugin?

Re: [Qgis-developer] compiling 2.16

[Richard Duivenvoorde]

Matthias/we pinned it down to probably a race condition when running
make in 1 thread (not using -j4 or so), AND therefor not having a
__init_.py in qgis dir...

Matthias did a fix, I've just tested and seems to work:
https://github.com/qgis/QGIS/commit/ae3db0a1bf9504b432e4553b94a56051576c053f

(and cherry picked to other branches)

Note: only if you run make without a -j4 option in a clean build/output
directory you hit this on,
else __init__.py is just available...

Regards,

Richard

[matteo]

Hi Marco,

on Ubuntu 16.04 and no ubuntugis. Same here..

But, after a second and a third attempt the core dump disappeared..

Another problem I'm experiencing is with all the plugins that use
QtWebKit; by activating them, I get a segmentation fault..

Cheers

Hello,

I propose a new Olympic sport for athletes open source programmers: the

The winner is who stays behind.

I think that you could check that the server does not return an exception.

If REQUEST=GetProjectSettings does not return an exception it means that
it's QGIS.


Example:
QGIS:
http://demo.qgis.org/cgi-bin/qgis_mapserv.fcgi?map=/web/demos/south_perth/project.qgs=WMS=GetProjectSettings

Not QGIS:

Unicode type release name (str type in python 3) must be compatible
with the saying.

Fixing the error would be easy for the relevant python devs. But if
the change was introduced in 3.0 (`type(QGis.QGIS_RELEASE_NAME)` gives
me `` in QGIS 2.14. Not sure that it was technically
possible to keep str type for the constants), QGIS 2.16 users didn't
have to wait for the relevant plugin devs to release a modified
version.

Yes, this should be Python 2.xx's developer haiku: *Bytes on the outside,
unicode on the inside. Encode/decode at the edges. *It's a bad habit in
Python 2.xx to cast to str when the string probably could contain accented
chars (e.g doing *str(layer.source()*). But in Python 3, str is unicode,
most of problem would probably be gone. For some strategies, perhaps what
we did in InaSAFE could be useful, see the 3rd comment in this PR:

I don't think the type has changed. Before python just converted it
silently because the conversion of a pure ascii unicode string was trivial.
Compare:

>>> str(u'Essen')
'Essen'
>>> str(u'Nødebo')
Traceback (most recent call last):
  File "", line 1, in 
UnicodeEncodeError: 'ascii' codec can't encode character u'\xf8' in
position 1: ordinal not in range(128)

As a general rule of thumb: don't cast to other types if there is no
requirement, that will help to prevent such issues and make the upcoming
upgrade to python 3 much easier.

Hi Minoru,

this is probably done to handle 'Nødebo' name for 2.16...

though you could say it is a api-change... I think easiest is to fix it
in plugins? Which (while Python2) should maybe move all str() calls to
unicode() ones?

Not sure there is an easier solution now after 2.16.0 ?

Regards,

Richard

That's not robust, with a rewrite you can easily hide/alter that path.

I suggest you to rely on a WMS getProjectSettings call.

AFAIK that call is unique to QGIS Server.
