Re: [Qgis-user] error using the stand alone app Oceanmap

3. if no installation has been found, fire up a simple UI in PyQt and
let the user select the installation directory.
I would like to come up with something in the same direction:
In both apps presented in this thread everything seems to be relying on
the path that is hardcoded into qgislite.py and mainwindow.py
repectivly. The variable used is qgis_prefix = /usr/local/qgis_svn
(line 55).
I do not use a svn version of qgis. Instead I use the Ubuntu packages:
whereis qgis
qgis: /usr/bin/qgis /usr/lib/qgis /usr/share/qgis
Due to some to me unknown reason, the standalone apps and python
tutorials only work on my Ubuntu box when I set the path as follows:
qgis_prefix = /usr
I would recommend to use the where command for linux systems to get the
install folder.
Some pseudocode:
test if on linux
execute in bash `whereis qgis`
whereis_output = read output from that command
qgis_prefix = whereis_output
if on windows
use the approach Martin pointed out:
(${PROGRAM_FILES}/Quantum GIS
note that some users like to change the default install folder
to something like c:\programms\qgis
else (installation folder can't be found
open a gui folder selection dialog and let the user select it.
Maybe I haven't explained it well, but this is what I meant, just
without running whereis utility. Since it just looks to /usr and
/usr/local directories we don't have to run it and look there by
ourselves.
As a workaround we could use a configuration.py file. There we set the
paths and the parameters for the app:
cat configuration.py
qgis_prefix = /usr
startup_project = ./data/mycustomproject.qgs
So if you deliver the app and your users have problems to start the
program they'd only need to modify this configuration file and wouldn't
need to mess up with the rest.
Yes, script with just configuration is a simpler variant of a
bootstrap script. In fact we should be able to support also gui-less
configuration (since qgis libraries can be used also without gui).
I think what the maximum would be to achieve real stand alone apps: ship
a directory with these resources in the app.
|-- LICENSE.TXT
|-- Makefile
|-- README.TXT
|-- core
|-- data
|-- qgis_common
|-- qgislite.py
`-- tools
Then every needed file could be put into the common directory
(qgis_common). And we are totally independant of a QGIS install.
Right, this is suitable for windows. But I would say that e.g. for
linux it's more appropriate to ship standalone apps and let the user
install the libraries with package manager.
In case of using many stand alone apps one would put the qgis_common
somewhere else and refernce it with the qgis_prefix variable.
Well, this are just some ideas. They only based on brainstorming and
didn't undergo testing here ;-) Hope you like them.
Of course thanks for ideas!

3) You can play with a new project I am starting to develop called QGISLite.
It can be found here:
http://trac.reprojected.com/qgislite/
The intention of this project is to create a very minimal GIS app based on
the python bindings to QGIS that stand alone apps can be built against. I
just started that one, but look forward to adding to it. The SVN for that
one is:
http://svn.reprojected.com/qgislite/trunk/
Aaron,
QGISLite looks nice :-) What will be the way to build standalone apps
against QGISLite? Are you going to implement QgisInterface so that
regular python plugins for QGIS could be used or use some other way?
Btw. it has been crashing for me when exiting (on linux) - the reason
is that garbage collection first deletes QApplication instance and
later before destruction of something related to QgsMapCanvas (don't
know what so far) wants to paint to QPixmap and that's not possible
anymore. This behaviour was happening also in the tutorials ported to
python. This may be caused by the merge of incremental rendering
support but I'm not sure. Anyway, it's possible to workaround it by
creating application in one function and then doing the rest of
initialization in other fuction so that first python will collect all
gui-related stuff and at last the application, i.e.:
def doInit():
app = QApplication(sys.argv)
initApp(app)
def initApp(app):
# ... stuff ...
At last one thought:
What sucks about custom qgis-based application is the need to find out
the QGIS installation and set the paths to PyQGIS, QGIS libs and QGIS
resources. It comes to my mind that we could possibly do a simple
bootstrap python script that application could use. The bootstrap
script could work as follows:
1. check availability of PyQt4. if not available, quit gracefully and
tell the user about the problem in a way that they can understand it
2. try to find QGIS in some default paths (/usr, /usr/local on linux
or ${PROGRAM_FILES}/Quantum GIS on windows etc.) or try to use a
previously saved path to QGIS installation from QSettings
3. if no installation has been found, fire up a simple UI in PyQt and
let the user select the installation directory. If the user doesn't
have QGIS installed at all, it could guide him to download and install
it for his platform - or even just download the necessary files like
libraries, providers and some resources like SRS database.
4. check whether the QGIS version is compatible (i.e. = 0.9)
5. if everything is correct, let's set path to the bindings (modify
sys.path), path to the libraries (os.environ['LD_LIBRARY_PATH'] on
linux) and path to the resources (QgsApplication.setPrefixPath)
6. everything is ready :)
What do you think about that? Such script could be included in QGIS
sources so any project could copy it and use for bootstrapping.

Re: [Qgis-user] using rubberband as temp geometry

My map is now showing a rubberband/geometry, and some label, but when I export it to an image, the label is there, but the geometry vanishes? Right, rubberband is a map canvas item so it's not a part of the map. When exporting map as an image I think it's correct not to show map canvas items as they are usually used for some map tools. Is that the implementation of the rubberband? Or am I responsible myself for painting those 'temporary' features? Or am I supposed to make some 'memory-vector'-layer, and add the rubberband as a geometry to that using 'setToGeometry'? (Tried that, but got an attribute-error (using 9.1 on debian)). Or something else? No canvas items are exported to the images. If you need this behaviour you should be able to use function of ancestor of map canvas - QGraphicsView::render() - that can render the complete map canvas contents to output and not just the map.

At the moment we want to implement a geoprocessing plugin with functions like buffer, union, difference etc. At the moment we realised it with Shapely. But this approach with third party libs is not nice and would be obsolete when QGIS offers the mentioned methods. QGIS native methods() based on GEOS would be the much better approach! What are your plans? Do you plan to implement union(), difference(), intersect() and relate() as QgsGeometry methods? Since adding the geometry operations is just simple passing the call to GEOS routines, I've added in r7994 more processing - difference, union, intersection, convex hull, symmetric difference. (we're in feature freeze but since these additions don't infere with any other part of QGIS I think it's ok to add them) A second question. I want to create a dissolved buffer polygon. To achieve this it is neccessary to combine all single objects p.e. LineStrings to one MultiLineString before buffer(). How do I concatenate single Linstrings into one Multilinestring? Well, you can create an instance of QgsMultiPolyline (which is in fact vector of vectors of points) and export one by one all geometries to it using QgsGeometry::asPolyline() and then saving them again as geometry using QgsGeometry::fromMultiPolyline().

If you won't use any OS-dependent python modules, it will be portable - everything will just work :) I fear that I underestemated the python story, but will try anyway. There are so much nice free arcview3 scripts available to 'port' to qgis, and python seems a ideal language for this. I hope that getting python bindings to work won't be a headache.

The discussion we had was not about _how_ but it circled around _if_. Ah I confess to not going back to the archives... I guess we could always put in a USE_RPATH flag into cmake so people can pick their preference and then just wrap the rpath stuff in a IF (USE_RPATH) blah ENDIF (USE_RPATH) How does that sound? Going again through discussions on several mailing lists (debian, cmake, kde), I still don't know how to do this right. Some say that using rpath is great because it forces to use harcoded runtime paths, other say it's evil because of that. Bad thing is that rpath overrides LD_LIBRARY_PATH setting, which might be confusing. Also it adds some pain to distributors (IMHO). But it makes life easier for users which compile the software by themselves and don't use packaged versions. So, what to do? I would say that the best choice is to forget rpath completely and let users set LD_LIBRARY_PATH manually. But if you insist to use rpath, then the best way is the one you propose: make it configureable and turn it on by default.

Re: [Qgis-user] Build QGIS from source
When I then run ~/apps/bin/qgis I first get this: ./qgis: symbol lookup error: ./qgis: undefined symbol: _ZN10QgsMapTool9setActionEP7QAction This is surely due the fact that your system uses wrong libraries - it chooses those in e.g. /usr/local/lib but it has to choose the ones which are in ~/apps/libs How to do this - set LD_LIBRARY_PATH variable - it will add the specified dirs to the library search: export LD_LIBRARY_PATH=~/apps/lib This should also go to the wiki...

Are five working days enough as a voting period or should it be longer? I like the template, five working days seem OK to me. Author of the RFC should also add a FAQ section and fill it with questions and answers based on the discussion on the mailing list. In case that RFC is changed based on the discussions, the voting should get another five days. Also what about the cases when later the dev finds out that he needs to do things differently? Change the RFC and start voting again? Or create a new RFC ...? BTW.

Hi Tom, building with autogen.sh or configure script is broken at the moment - currently we're trying CMake as a replacement of current automake autoconf build system.
