who is calling `get_treestore`? if the input come from the user I prefer
check the input and then call, or not, the function. if the input come

[pygtk] DLL load errors with Py2.6, PyGTK 2.22 and GTK 2.22 bundle

2010-11-28 Thread Paul Goins


Hello,

I recently upgraded my GTK/PyGTK installation due to some missing API
calls.  However, since doing so I now am now unable to run my PyGTK
application.

Running through the testing instructions on the FAQ
(http://faq.pygtk.org/index.py?req=showfile=faq21.001.htp):

As far as I can tell, I'm meeting the specified requirements.  System

Does anyone have any ideas on how to get this going?  Thanks in

Another important point: if dependency walker reports a single missing .dll
file (libgio-2.0-0.dll is a likely candidate), you've got a good chance that
a different directory on your PATH contains an older gtk+ runtime.

In that case you should check the properties of one of the other dll files.
Right click LIBGLIB-2.0-0.DLL in the dependency tree and click properties.
Then check the Location field. If it is not C:\gtk_bundle\bin you'll need
to fix your PATH environment variable.

Dieter

I see gramps lists graphviz as an optional dependency. Beware that
graphviz installs it's own gtk+ runtime (and might add graphviz to
PATH). This could be one reason some of your windows users are having
problems.

If the graphviz directory comes first on PATH (before the gtk+ runtime
version required by pygtk, pygobject and pycairo), the python bindings
will try to load the necessary dll files from an unexpected location,
most likely having and incompatible gtk+ runtime.

Just a thought...

Hi Dieter,

Thanks for pointing the problem out

Yes, .. we are aware of this, and is part of the reason why the script 
check_gtk_install was created, to try and highlight when people have 
path issues ( whose gtk comes first).
I think most people on a pygtk forum have some sort of developer 
background, .. but our users on GRAMPS come from all walks of life, and 
some are not necessarily technically savvy and have real problem just 
installing the gtk / pygtk stack. If they get that far and then  have 
DLL load failures it all gets too hard for them to diagnose. I think on 
windows we have lost a lot of potential GRAMPS users just because the 
gtk / pygtk stack is too hard for them to install.


Now days most people start GRAMPS with a batch file that puts the bin 
directory of  GTK rutime GRAMPS wants to use on the path in front of all 
others - therefore the path modification is only valid for the duration 
of the session, and isolated to that one process.


whinge
Personally I have a lot of problem with GTK applications that ship a 
local copy of GTK putting their copy on the path for all to see.
I don't see that problem with GIMP, .. while they ship a local copy of 
GTK, they don't put themselves on the path, and I think that's a model 
other shipping gtk apps could follow.


It's no wonder a globally installed gtk runtime, is so problematic when 
it's got to fight with various local gtk installs getting in the way.


In fact now we are starting to find something has installed some DLL's ( 
i.e. intl.dll, iconv.dll)  to windows\system or windows\system32, this 
causes a major problem as this path gets checked BEFORE the path, so 
even you put your global gtk-runtime first on path, it will still find 
the wrong copy of intl.dll.

I've been using that solution myself for some years now (I no longer
tolerate any package that uses gtk+ to change PATH on my system, so
there's a couple of bat files I use for monodevelop, glade, ...)

Yeah, gimp is one of the few that actually gets it right on windows...

Yep, changing PATH should never have been advertised as a way to
get software using gtk+ working on windows. It's all great as a trick
used by developers, but in the end it bites users. Hard.

In fact now we are starting to find something has installed some  
DLL's ( i.e. intl.dll, iconv.dll)  to windows\system or

I encountered that problem last year. Don't remember what package did
it... As you said, the PATH problem can be handled but system/system32
simply breaks everything...

Re: [pygtk] Gnome panel applet troubles

Subject: Gnome panel applet troubles

Hi all,

I'm having some troubles with how my gnome panel looks. I've attached some 
screenshots so you can see what I mean.
The left applet is the hamster applet for time tracking. The applet on the 
right is my applet.

As you can see in the first screenshot (Screenshot-3.png) the background of my 
applet is weird. The lower half is another color than the top part.
If I hover over my applet (Screenshot-5.png) the background turns bright. The 
hamster applet doesn't have that.

And it's even weirder when I put a label in it. Then the color of the font in 
the label is very dark so it's almost unreadable.

What could I be doing wrong? I don't get it.

My Applet init method:

def __init__(self, applet, iid):
logging.debug('__init__')

# save the applet object
self.applet = applet

# determine the size to draw the icon
size = self.applet.get_size() - 2

#Get theme, find SVG icon and put it in a pixbuf
theme = gtk.icon_theme_get_default()
pixbuf = theme.load_icon(self.icon_name, size, 
gtk.ICON_LOOKUP_FORCE_SVG)

#Load image
image = gtk.image_new_from_pixbuf(pixbuf)

# set up the applet tooltip
self.applet.set_tooltip_text(self.title)

self.button = gtk.Button()
self.button.set_relief(gtk.RELIEF_NONE)
self.button.set_image(image)

self.button.connect('button-press-event', self.button_press)

self.applet.add(self.button)
self.applet.show_all()

Thanks in advance!

Thanks. It seems I have new dependencies which did not exist with the
previous version. (I deleted the old versions of gtk/pygtk
completely, so I don't know what version they were, unfortunately.)

Dependency walker image is here:
http://www.vultaire.net/mail_attachments/_gtk.dwi

Basically, I get 3 DLLs missing, and the immediately relevant part of
the dependency walker image looks like this:

(?) MSVCR90.DLL
Error opening file. 指定されたプロシージャが見つかりません。(2)
Dependency chain: _GTK.PYD/MSVCR90.DLL

(Hourglass/?) GPSVC.DLL
Error opening file. 指定されたプロシージャが見つかりません。(2)
Dependency chain:
_GTK.PYD/LIBCAIRO-2.DLL/USER32.DLL/ADVAPI32.DLL/WINTRUST.DLL/CRYPT32.DLL/USERENV.DLL/GPSVC.DLL

(Hourglass/?) IESHIMS.DLL

Dependency chain:
_GTK.PYD/LIBCAIRO-2.DLL/USER32.DLL/ADVAPI32.DLL/WINTRUST.DLL/CRYPT32.DLL/USERENV.DLL/SHELL32.DLL/SHDOCVW.DLL/IEFRAME.DLL/IESHIMS.DLL

Seems at the least there's a Visual Studio dependency in MSVCR90.DLL.
I can grab a copy somewhere of this; not a big deal. The other stuff
seems like it's only maybe required.

Anyway, this wasn't a GTK dependency at all in this case. Perhaps the
wiki should be updated?

2010-11-28 Thread Stephen George

Hi Paul,

MSVCR90.DLL is a requirement for many applications. (built with
Microsoft Visual C++)

See Microsoft Visual C++ 2008 SP1 Redistributable Package (x86)
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=a5c84275-3b97-4ab7-a40d-3802b2af5fc2

I think MSVCR90.DLL is a dependency of pyGTK, your old pyGTK you where
running probably had a dependency for an old version of the MS C
Runtime, which would still be installed on your HD somewhere, but just
not compatible with the new pyGTK.

See if installing the MS runtime above fixes your problem.

Steve
