[Qgis-developer] Random uniform on Field Calculator
Would it be possible adding a key for generating a field according to a random uniform distribution in the Field calculator? This would be very useful for selecting a subset of points or polygons.

Re: [Qgis-developer] plugin development in Win XP
Thank you Alex: I did build earlier using the instructions given on the web that you referred to. I was also able to run the QGIS (the built version) executable (after manually copying several libraries that were needed). I now wanted to add my own plugin.That is when the real challenge started. I could compile the dll's that came from the trunk. I tried to add my own project following the plugin development directions and I could not get very far. That is where I am today. I do have experience with C++ and visual studio. I have written a few standalone applications that I want to run from within QGIS. Right now I am trying to make a simple dll as per the instructions given on the web and it has not gotten me anywhere. I tried rerunning CMake and I get a new error that I did not get before, and if anyone of you have any idea why let me know. I do have SIP installed and I even went to the extent of compiling it myself and CMake still could not find it. Quantum GIS version: 1.7.0 Trunk (10700) Found GRASS: C:/OSGeo4W/apps/grass/grass-6.4.0 (6.4.0) Found Iconv: C:/OSGeo4W/lib/iconv.lib Found Proj: C:/OSGeo4W/lib/proj.lib Found Expat: C:/OSGeo4W/lib/libexpat.lib Found GSL: C:/OSGeo4W/lib/gsl.lib;C:/OSGeo4W/lib/cblas.lib Found GEOS: C:/OSGeo4W/lib/geos_c_i.lib Found GDAL: C:/OSGeo4W/apps/gdal-17/lib/gdal_i.lib Found QWT: C:/OSGeo4W/lib/qwt5.lib CMake Error at cmake/FindSIP.cmake:54 (MESSAGE): Could not find SIP Call Stack (most recent call first): CMakeLists.txt:399 (FIND_PACKAGE) Any help is greatly appreciated, Maaza --- On Sat, 2/5/11, Alex Mandel tech_...@wildintellect.com wrote: From: Alex Mandel tech_...@wildintellect.com Subject: Re: [Qgis-developer] plugin development in Win XP To: qgis-developer@lists.osgeo.org Date: Saturday, February 5, 2011, 8:32 PM I think what Giovanni was implying is that you should setup to build QGIS from source and that once you have that working your build environment should work for plugins.

With the plugins, Dr. Marco's document is written for Linux and then it is also not clear. I think the instructions given for the update of the source files are not correct. What are the required directories for the plugin? Do I need all the extra files cmake, .cxx, .svg, etc for the plugin to work? Just wondering if I am making demands that is not acceptable.

Re: [Qgis-developer] multi-view
I started working on something similar the other day as I could not get this
patch to apply and thought about a different way of going about it.
The general idea is to use a QMdiArea(tabbed or floating) as the central
widget for QGisApp class. You can then create a new window using
QMdiArea.addSubWindow(QgsMapCanvas). You would then connect to the sub
window changed event to know when the user changed windows in order to
update the legend, undo stack, tool etc.
The general layout and rules are:
1. There is only one active canvas at a time.
2. The active canvas is stored in the mMapCanvas QgisApp variable. This
is updated when the user clicks on the map or tab eg on subWindowChanged
signal
3. When the user clicks a tool it sets the tool for the current canvas
active via. mMapCanvas.setMapTool({maptool} the map tools canvas is
updated using {maptool}.setCanvas(mMapCanvas). This means there is only one
instance of {mapTool} just it's canvas gets changed.
4. On subWindowChanged the legends canvas is updated to reflect the new
maps layers.
5. Opening a vector layer opens it in the curent active canvas.
6. Try a limit the amount of new code code added, try and use as much
that is already there.
7. Being able to switch between tabbed or floating windows would be very
powerful.
I know this is no easy task, no matter which way you run with it. And there
a lot of user cases which needed to be taken into account.
I was thinking about pushing what I have to git hub tonight if anyone is
interested.
Just my thoughts on the subject.

[Qgis-developer] Poor asynchronous performance of Python threads?
Hello list, I have been playing around with the development branch of IPython (0.11-dev) as they have built a PyQt-based console that supports all sorts of awesome features like tab-completion, paged browsing of function code and docstrings, and Pygments-powered syntax highlighting in addition to the normal IPython goodness. I slapped together a quick plugin that adds an IPython-based console to QGIS. The code is available at: https://github.com/Sharpie/qgis-ipython To use it, you will need to install ZeroMQ, pyzmq, pygments and the dev version of IPython from: https://github.com/ipython/ipython The console fires up allright, but unfortunately very, very, very slow. There is about ~1-2 seconds of lag between invoking a command and receiving a response. For comparison, I threw together a minimal PyQGIS application that also uses the IPython console: https://gist.github.com/817914 The PyQGIS version is very snappy and there is no lag. I suspect the difference is due to the PyQt widget is talking to an external IPython process through ZeroMQ. When a command is executed, the console sends a message and then a Python thread waits for the response. With PyQGIS, Python is controlling the execution of the entire application. However, when the console is used as a plugin it is running in an embedded interpreter and it looks like QGIS takes a while to schedule the execution of the Python threads. Does anyone have any suggestions for solving or working around this issue? -Charlie ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
[Qgis-developer] open a WCS service
Hi all. My GDAL has WCS support. It is unclear however if and how could I open it. It is not present on the list of formats, and the interface requires a file rather than an address: should a button Open WCS be added to the GUI?
