I was wrong, I've tried now and you're right, it say that there's a conflict.
I don't know why but I remebered that the check were in both cases.

Anyway. probably the only way to avoid that a new version is masked
by an older one is to disable the installer.

Cheers.

Are you sure? When did this change?
A few months ago I had a situation where the plugin installer updated
gdaltools or ftools (or maybe both), and then later when I got a newer
built-in version, at startup it would complain that an older version in
my user directory was masking the built-in version, and tell me to
uninstall the old version.

at QGis startup the plugin manager checks if you have more versions of
the same plugin installed (i.e. one in the program dir and another one in
the home dir), then it loads only the newer one.

A shared directory *on a network server*?  Is there a standard way to

Re: [Qgis-user] plugin installer with unstable internet connections

[Nathan Woodrow]

Having the plugin installer install plugins into C:\Program Files\Quantum
GIS
Wroclaw\apps\qgis\python\plugins would require you to run QGIS as
administrator on anything > Windows Vista.

IMO plugins are user data and should go into the user home directory.

I would store the plugins on a shared directory and point everyones install
at that, disabling the installer is also a good idea.

Built-in Python plugins are installed in e.g. "C:\Program Files\Quantum
GIS Wroclaw\apps\qgis\python\plugins"

C++ plugins are installed in e.g. "C:\Program Files\Quantum GIS
Wroclaw\apps\qgis\plugins"

The plugin installer only installs Python plugins, and puts them in the
user's home directory, e.g.
"C:\Documents and Settings\Admin\.qgis\python\plugins"

If you are installing Python plugins manually, it would make more sense
to put them in "C:\Program Files\Quantum GIS
Wroclaw\apps\qgis\python\plugins", instead of having to copy them into
every user's home directory.  In this case you'd probably want to
disable the plugin installer, because if at some stage a user updates
one themselves, and doesn't keep it up to date, they could end up with
an old plugin version in their home directory masking a newer one in the
program directory.
It would actually be nice if the plugin installer could put plugins in
the program installation folder ("C:\Program Files\Quantum GIS
Wroclaw\apps\qgis\python\plugins").  I think the only way to achieve
this is with the --config-path option, but that way everyone also shares
the same settings.

Re: [Qgis-user] QGIS 1.7 Wrocław_problem copying entities after Joins

[Stanca Lazarescu]

Thanks Ramon for your answer. I tryed to save the layer as a shp but it
didn't work since the name of the colomns of the joined table were at times
too long to be accepted by the shp (10 characters maximum).

I finally managed to figured it out, the problem being nothing but the
edition mode. In order to copy the selection, the vector layer mustn't be in
the edition mode, because the joined table is supposed to permit no
alteration. It was as simple as that. Edition off and the selection and copy
into a spreadsheet is possible.

Cheers
Stanca

Sorry that was clumsy. 

Could you not save the join as a csv or a shape file and then open that up in 
excel?

So for the join I usually do, I only want parts of the join, so I select the 
bits I want and use "save selection as" to save that out. Usually I save that 
as a shp file, but even then the dbf can still be opened in excel. 

Admittedly I'm not using postgis, so there might be a postgis thing...

Thanks for the quick answer, both Tim and Anita,

Started copying the plugins from the following folder:
C:\Documents and Settings\Admin\.qgis\python\plugins

but got confused as I also found the following two folders:

C:\Program Files\Quantum GIS Wroclaw\apps\qgis\plugins
C:\Program Files\Quantum GIS Wroclaw\apps\qgis\python\plugins

Does anything from these folders also need to be copied?

Yes simply install all the plugins you need on one computer and then copy your

plugins from within that folder too if you prefer.

Re: [Qgis-user] plugin installer with unstable internet connections

[Andreas Neumann]

You can have your own local plugin repository in your LAN using a local 
webserver.


All you need to have is a folder with a file plugins.xml pointing to 
the zip-file containing the plugins. Have a look at the sourcecode of 
the XML file that are used by the other repositories. It is really easy 
to do.


Alternatively, you can move the plug-ins by hand into the python 
plug-ins directory without the need for a repository at all. The 
location depends on the platform and there is a distinction between 
machine-wide plugins and user plugins only visible by a certain user.


I believe the manual describes quite a bit about plugins installation 
and contains a pointer to the locations the python plugins are located.

Re: [Qgis-user] Problem rotating labels

[Andreas Neumann]

Hi all,

There are two versions of labeling (the old version in the layers 
properties tag) and the new version with the ABC button. The old version 
will be abandoned and replaced by the new version. So, if you create a 
new project it is recommended to use the ABC button. If there are 
problems/bugs, please make sure they are fixed by bug reporting them 
and, if possible fix it or hire someone to fix it.


Thanks,
Andreas

[Qgis-user] QGIS 1.7 Wrocław_problem copying entities after Joins

[s.lazarescu]

Dear all,

I'm using the latest version of QGIS, happy to be able to use the 'joins'
function. However, I'm stuck trying to exploit the information in an excel
after having joined two layers. Here's the whole story:

I have a vector layer (PostGis) representing geolocated enteprises of a
region in France. To this vector layer I joined a geometryless table
(PostGis) in order to enrich the information of the former layer (primary
key of the two layers = the SIRET code indicating the activity field of the
enterprises).

After having joined the two layers, what I need to do is select certain
entities and try to copy them in an excel table for further statistical
anylisis. The problem is that, no matter what the character enconding, only
the information from the mother vector layer is copied, while all the joined
colomns remain empty.  


Thanks a lot for helping 

Stanca

Re: [Qgis-user] Problem rotating labels

[Andrew Chapman]

I regularly have the same problem, but there are a couple of alternatives.
The one that I use is Layer Properties->Labels, Display Labels, select the
field containing label then the Advanced tab. You can now use the Data
defined placement->Angle to specify your angle field. You can also use the
same principle to use field dependent size, colour, etc. If nothing is
defined, QGIS simply uses the settings from the Label Properties tab. While
not documented anywhere that I've seen, you can also use the following for
Placement - 'Bottom Left','Left','Top Left','Bottom','Over',
'Top', 'Bottom Right','Right','Top Right'.
The other alternative is to use the ABC tool, but the only way that I can
see to get it to work is to first define fields for 'Label distance', 'X
Coordinate' and 'Y coordinate' - you will then have the option to select a
value for 'Rotation'. You could probably add a dummy field to your file
(using NULL values) and point the first three options there... but I haven't
tried that.

[bernhard . stroebl]

Hi,

you basically need a field for x and y coordinates each and use them 
for the label position.

Am I doing something wrong?

I am using Qgis 1.7.0 in Win 7 installed from the stand alone installer.

Best regards

Re: [Qgis-user] object labels

[Janneke Qgis]

Hi Nathan,
Thanks for the quick reply. I've once (a while ago) tried compiling my 
own qgis version and failed, and without adequate internet connection 
it's too much frustration to solve it. Maybe it's time to give it 
another go, if I can muster the courage, otherwise I'll wait for it to 
appear!

If you are able compile your own qgis version on windows (or other) 
you can get the code for my patch at 
https://github.com/NathanW2/Quantum-GIS/tree/expression-labels


I welcome any feedback you have if you are able to test it for me.

Dear Nathan,

is it already possible to use expression based labels, and if so,
how can we get it? If you need someone to do some testing on
Windows we're happy to do that.

 Until then you will need to create a new column.
