may I suggest to publish it anyway, as experimental (so people are
warned, and should not complain about missing support) or in extreme
case as deprecated?
IMHO having it in the main repo will make it much more likely someone
will get interested, possibly taking it over and carrying on its
development.
Thanks.

Here's a forked version of the old topocolour plugin, which does the same:

https://github.com/nyalldawson/topocolour

It's not in the QGIS plugin catalog because it comes with absolutely no
support ;) (I'm happy for someone to take over this if they're interested
in packaging it up properly and handling maintenance).

That said, it works in QGIS >= 2.0 and has numerous improvements to the
coloring algorithm.

Hi Leo

I had the same error a while back and I posted this to the UK QGIS
user group:

Anyone getting the following error on the latest update to QGIS via
OSGeo4W? The problem is a copy of msvcr90.dll in the
C:\OSGeo4W\apps\qgis\bin folder which clashes with the copy in
C:\Windows\winsxs\ folder.  Removing the DLL from the QGIS folder
allows the program to start without a hitch.


I had the same issue with the standalone 32-bit version on Windows XP.

In my case, deleting the dll from C:\Windows\system32 solved the problem.

[Joris Hintjens]

Hello,
I have a vector layer (points) and a wms layer.
I can get info from any point in the wms , and get as answer a html or text 
table with the properties of that point. How can I copy those values into a 
vector layer? From vector layer tovectorlayer, This can be done with Spatial 
Join. What about a raster layer as data source?

Re: [Qgis-user] BBox Filter for WFS

[Peter Borissow]

I'm not familiar with sponsoring QGIS development. The sponsorship page makes 
it sound like there's an annual commitment and there's no indication of how to 
direct funds for a specific task:

http://qgis.org/en/site/getinvolved/governance/sponsorship/sponsorship.html

Perhaps a kickstarter campaign would be better? I personally would donate my 
own time/money to get this fixed. Maybe others would too.

In any event (sponsorship vs kickstarter), we would need to know much money I 
would need to raise to support this initiative.
Thoughts/suggestions?

Peter

That's exactly how I would expect it to work.

To cache a whole WFS and start seems overboard, in that case why
wouldn't you just download the data set. BBOX is a must for web services
as a main part of the purpose is to allow users to only grab the part
they need when they need it.

Re: [Qgis-user] BBox Filter for WFS

[Peter Borissow]

Thanks Giovanni-    Do you know when the dev team is planning the next release? 
I wonder if there's time to get this fixed before the next release.

That's exactly how I would expect it to work.

To cache a whole WFS and start seems overboard, in that case why
wouldn't you just download the data set. BBOX is a must for web services
as a main part of the purpose is to allow users to only grab the part
they need when they need it.

Thanks,
Alex

Re: [Qgis-user] QGIS 2.8 runtime error

[McDonaldR]

Hi Leo

I had the same error a while back and I posted this to the UK QGIS user group:

Anyone getting the following error on the latest update to QGIS via OSGeo4W? 
The problem is a copy of msvcr90.dll in the C:\OSGeo4W\apps\qgis\bin folder 
which clashes with the copy in C:\Windows\winsxs\ folder.  Removing the DLL 
from the QGIS folder allows the program to start without a hitch.  If you have 
QGIS DEV installed there is no issue.

This post provided the answer and method: 
http://stackoverflow.com/questions/14552348/runtime-error-r6034-in-embedded-python-application/14680947#14680947

This happened after using the OSGeo4W installer to upgrade to QGIS 2.6.1-2

Whether this is just my install environment or affects everyone, I don’t know.

Hope it helps

Ross

Subject: [Qgis-user] QGIS 2.8 runtime error

Hi QGIS Users,

I have this problem when opening QGIS. It reports:

Runtime error:
Program C:\OSGeo4W\bin\qgis-bin.exe
R6034
An application has made an attempt to load C runtime library incorrectly. 
Please contact the application's support team for more information.

After clicking "OK" it loads QGIS. I have not tried to process anything so I 
have no idea if this will affect some of the functions in QGIS.

I am using Windows 7 64 bit. Installed QGIS via OSGeo 32bit.

note: I already restarted my laptop.

Thanks in advance for any help,
-Leo

[Qgis-user] Re : [Qgis-developer] Pyqt4 : which signal is sent when dialog comes to foreground?

[Junior]

Hi all, Luca
Thanks for answering. But i already have an update function that I linked to an 
update list button. I even linked it to the icon on the toolbar so that when 
user calls foreground the dialog it's already updated.
The case I'd like to manage: user can open plugin dialog and composer manager. 
The two dialogs are visible (to the eyes) even though composer manager is the 
one at foreground. He makes changes and directly clicked on the plugin dialog. 
He should update list but if he forgets and executes, this may lead to bug I 
don't want to / can't yet manage.
Reason why I want to ensure that list is always up to date when he interacts 
with the dialog

You could add a "Update list" button
