Problem with Liquid-weather dependency on Phyton

I have just updated to KDE 4.1 and run superkaramba with the Liquid-weather applet. I have been using that applet with KDE 3.5 for a long time but now with 4.1 there is a problem.

After starting the applet appears a dialog with the following:

"You do not have PyQT installed.  This is a critical dependency for Liquid Weather ++.  Please install it and try again."

The following is the python function that checks the dependencies (I have no idea of Python):

def checkDependencies(widget):
    global hasReportlab, hasqt
    try:
        from reportlab.platypus import SimpleDocTemplate,Paragraph,Spacer
        hasReportlab = 1
    except:
        hasReportlab = 0
    try:
        from qt import *
        hasqt = 1
    except:
        karamba.execute('kdialog --title "%s" --error "%s" &' %(_('Critical Error'),_('You do not have PyQT installed.  This is a critical dependency for Liquid Weather ++.  Please install it and try again.')))
        sys.exit()
    if os.popen('which convert').read() == '':
        karamba.execute('kdialog --title "%s" --error "%s" &' %(_('Critical Error'),_('You do not have ImageMagick installed.  This is a critical dependency for Liquid Weather ++.  Please install it and try again.')))
        sys.exit()

I have installed Python:

[alf@pcalf ~]$ pacman -Q | grep py
compizconfig-python 0.7.6-1
pycairo 1.4.12-1
pygobject 2.14.2-1
pygtk 2.12.1-1
pykaraoke 0.5-1
pyqt 4.4.2-1
pyqt3 3.17.4-1
pyrex 0.9.8.4-1
python 2.5.2-5
python-numeric 24.2-2
python-pygame 1.8.1-2
pyxml 0.8.4-3
wxpython 2.8.8.0-1

Any idea?

Re: Problem with Liquid-weather dependency on Phyton

Can't you change to one of the weather applets for kde4.1 instead of using superkaramba?

Edit: the package you are lacking is probably pyqt3

Liquid weather is by far the best weather applet I have ever seen. It has a lot of features.
I only use superkaramba to debug the problem. Plasma is compatible with superkaramba applets.

Edit: the package you are lacking is probably pyqt3

As you can see above, I already have pyqt3 installed.

Re: Problem with Liquid-weather dependency on Phyton

I found the following and that trick allows you to start the applet. I seems to work properly but sometimes crashes plasma.

How get it working on KDE 4

Figured out how to fix it for KDE 4
(google is my friend)

Heres the steps :-

First, make sure you have the package python-qt4 installed.

Using the Add Widgets, select Install from File. Choose SuperKaramba. Click Next and find the lwp-15.0.skz. and Click Finish.

The contents of the skz will be extracted to ~/.kde4/share/apps/plasma/plasmoids/sk_lwp-15.0

You need to modify the file liquid_weather.py. In the method checkDependencies(widget), it tries importing qt libs, which for whatever reason fails. So comment (or remove) out the following (lines 3663-3668)

hey presto it all now works.

Hope it helps
