Re: [QGIS-Developer] C++ Plugin plugin_builder.py

[Siki Zoltan]

Dear Susann,

you have to install plugin builder plugin frm QGIS 3.4
Go to Plugins/Manage and Install Plugins in the menu and search for Plugin 
builder.


There are sources how to upgrade plugins:

Hi,

I miss the plugin_builder.py in the src/plugins/ in ltr-3_4.

The last I found was in 2.18 but this doesn't work for me because the
version of Qt has been changed.

I need an example for upgrading my plugins, thanks for a hint.

Not sure, but I think Otto (in bcc) has something to do with it, or
maybe he knows the actual packager?

Re: [QGIS-Developer] GSoC 2019 for QGIS 3D Improvement Proposal

[Tim Sutton]

Nice proposal Sunni! On the Mac the 3d window is a bit of a pain because it is 
a dock window so cannot be maximised easily and when you do resize it it tends 
to dock into the main window so it always makes it a bit clunky in demos. It 
would be really nice if it either replaced the main 2d map canvas or was 
possible to use it as a normal window instead of a dock widget so you can 
easily maximise it.

Oh and then please implement some kind of star wars tie-fighter vs x-wind chase 
through my neighbourhood game as an Easter egg in it :-)

Tim

Hmm, yeah, I will think about it in the design. I agree, if it can be used
on other part, it will be better for sure.

 Hi Nyall,

Great proposal Ismail -- all these features would be lovely to see!

As Martin said, it's a good point. I will be happy to re-use existing code,
I think it's a win-win solution.

Yeah, regarding the billboard, that's one of the common use cases that
Martin and I discussed. So it's under my radar to have something like that
in the implementation. Btw, thanks for your comments in the Google Doc.

Those two ideas are interesting and should be implemented somehow in the
future. But as you said, perhaps it's too much for the GSoC proposal :). I
can't promise, but who knows what will happen in the future :)

Just to add more thoughts to this... There is obviously a lot of
confusion regarding geometry API in QGIS since the big refactoring.
Things like QgsGeometry vs QgsAbstractGeometry ... or QgsPoint vs
QgsPointXY. I would say some bits are fixable without too much effort
(e.g. add some missing convenience constructors), but most bits will
need to wait until QGIS 4.0 (e.g. getting rid of methods
accepting/returning QgsPointXY within geometry API).

One idea that I wanted to explore is whether we could avoid having
QgsGeometry in the Python API at all, so it would be a mapped type
like QVariant is in PyQt5. So for example, feat.geometry() would
return directly QgsPoint or QgsLineString. This would avoid the need
to extract the internal geometry object from QgsGeometry and vice
versa (wrap internal geometry object into QgsGeometry). I have not
tried it in practice yet though and it will definitely be an API
break, but if it works, it should simplify things a lot :-)

Cheers
Martin

Re: [QGIS-Developer] GSoC 2019 for QGIS 3D Improvement Proposal

[Andreas Neumann]

Hi Ismail, 

Looks nice - thanks for the proposal. Hopefully it will be accepted! 


I'd love to see all of these improvements, esp. the billboard ones -
because currently there is no way to properly label something in 3d. 


I added a suggestion for the billboards: Allow leader lines between the
original point feature and the billboard location above the point
feature, with a configurable vertical offset (best also data-defined).
It would help better locate the position of the actual feature that is
labeled. 

- 

There are two other ideas regarding QGIS 3D: 


* allow highlighting of objects in 3D when using the Identify tool.
Currently one can pick an object in 3d and query the attributes, but
there is no visual feedback what object was actually selected. perhaps
with the new line rendering that Martin is currently working on, this
could be used to draw a red 3d outline of the object picked?
* allow a per layer (or per category) wireframe mode for 3d polygons
and terrain (in order to be able to look through the terrain or 3d
objects).

I understand that this would be too much for the GSOC proposal, but
nevertheless I would like to mention those here, as I think they are
important. I totally understand, of course, that they are too much for
the GSOC proposal. 

Thanks and good luck, 

Andreas

Re: [QGIS-Developer] cannot import processing algorithm in 3.6

[Raymond Nijssen]

Thank you Nyall!

Sorry for replying so late but I suddenly went on a busy 2 week trip abroad.

Last HF martin and I discussed the current geometry model and some of 
the flaws and weird things. Especially the set() and get() are not very 
logical function names to me.


To find out about the model I tested it using a script in the qgis 
python console. I'm still using it often to figure how to create and 
convert geometries. Hope it helps others as well. Would be nice for the 
cookbook maybe.


Kind regards,
Raymond

Thanks Nyall, that works!


Great, thanks for the confirmation. And because I've got to do mapping
all day, I'm in a good mood, and you get a free PyQGIS lesson:

geom.get() : gives you the underlying fundamental geometry object
attached to the feature. QgsFeature.geometry() returns a QgsGeometry
object, which is more or less a "container" for geometries. It's got
some convenient methods which apply to ALL geometry types, but
sometimes you need to dig down to the actual geometry primitive. In
that case you use geometry.get(), and you get the fundamental
QgsPoint/QgsLineString/QgsPolygon/etc object. It's actually generally
preferable to call "geometry.constGet()", IF you are doing some
operation which doesn't alter the geometry in place (like you are
here). But that's a complex microoptimisation.

geom.get().boundary() gives you the topological boundary of the
primitive. For polygons this is their exterior + interior rings, for
lines it's their start and end point (unless it's a closed ring, in
which case you get a null geometry). Points have no boundary. Using
boundary() to convert polygons to lines is the most efficient method -
it's very heavily optimised, and works perfectly with curved geometry
types and maintains any Z or M values which may be present.

Lastly, you need to wrap the result back up into a QgsGeometry object
- hence QgsGeometry(boundary() ). This is because most of QGIS API
works with QgsGeometry objects (remember, they are like "containers"
holding a geometry), and NOT the fundamental geometry objects.

Done! A super-efficient, rock solid approach which will work with all
input geometry types. Win!

(for reference - this is what the polygons to lines algorithm actually
does in the background too)

Nyall











I will try tomorrow.

One last question, it seems to me like the old code is working again in
3.7. Can you confirm that?


Shouldn't be -- maybe you have a leftover .py file here?


Indeed. I did a clean install and it is not working in my 3.7 anymore.

Raymond

Great proposal Ismail -- all these features would be lovely to see!

Reading over the billboard proposal, I'd strongly suggest that you
re-use QGIS marker symbology here to render the actual billboard
content. Amongst other benefits, this would allow re-use of identical
symbols between 2d and 3d maps.

Best of luck with the coding!
Nyall

Re: [QGIS-Developer] GSoC 2019 for QGIS 3D Improvement Proposal

[Mathieu Pellerin]

Regarding on-screen navigation, it'd be good to think of an implementation
that would work for both 2D as well as 3D map canvases when conceptualizing
the way ahead (I'm not suggesting you implement this as part of this GSoC
plan, just seeding the idea as it might shape way you move forward). It'd
be useful in a few places across QGIS to have some ultra basic zooming and
panning controls attached to a qgsmapcanvas.

Always nice to see some more love thrown at our 3D support :)

[QGIS-Developer] GSoC 2019 for QGIS 3D Improvement Proposal

[Ismail Sunni]

Dear QGIS developers,

My name is Ismail Sunni, I am from Indonesia. Currently, I am studying in
Germany for my master degree. Since I am now a student, I want to
participate in this year Google Summer of Code for QGIS. I am interested to
contribute and work on the 3D improvement
.
It's still young and I think that I can help with making it more complete.

I have discussed with Martin Dobias for a more detail idea and start my
proposal. Now, my proposal is more or less ready (according to me). But it
would be better if I get some feedback or suggestions from the QGIS
community itself. Since it will give impact to the community.

If you are interested, you can check my proposal in this URL:
https://docs.google.com/document/d/1RcXiEyziQyGurqDGRBN3g-het33liVD81WFjv8qQlt8/edit?usp=sharing

Please don't be hesitate to make a comment either in this email thread or
even in the document itself.

Thank you

Best regards

[QGIS-Developer] No LTR on openSUSE repos

[Yann POUFFARIX]

Hi,

Just a little mail to ask if the LTR version will come back because we have
over 300 users waiting for a Computer Update but we can't do it if we can't
use the LTR version of Qgis.

We don't see any communication about the suppression of LTR version for
openSUSE repos.


Sincerely,

[QGIS-Developer] C++ Plugin plugin_builder.py

[SSchmidt]

Hi,

I miss the plugin_builder.py in the src/plugins/ in ltr-3_4.

The last I found was in 2.18 but this doesn't work for me because the 
version of Qt has been changed.

I need an example for upgrading my plugins, thanks for a hint.

Re: [QGIS-Developer] Proxy support in Python Plugins

[Richard Duivenvoorde]

Duh, sent to Nils alone, resending to list 

@nils: in addition I forgot to tell: please have a look at
https://github.com/rduivenvoorde/qgisnetworklogger a Work in Progress
which will show you all information (url, headers etc) that goes through
QgsNetworkAccessManager and replay it if needed

Regards,

Richard Duivenvoorde
