Double check you are not trying to run the 32 version on your 64 machine. There are two installers on the page, it might sound silly but make sure you've got the proper version
Traceback (most recent call last):
File "hello.py", line 10, in <module>
from PyQt4 import QtCore, QtGui
ImportError: No module named PyQt4
Where can i get it ?

I think it means that PyQt4 is either missing or not installed properly. You can get it for your desktop machine from http://www.riverbankcomputing.co.uk/.../pyqt/download.
Im not sure if, by running XP as a virtual machine, how that may effect the installation.
On the n900, you can download it from app manager or it'll come with other applications you install that make use of python. I think gpodder is one of them..

I intentionally threw out a lot of dependencies of that package so they could start off with a reasonable minimum. That means Core, GUI, XML and Help. Core and XML are IIRC part of PR1.1.
So it's cool.. install from app manager.. fair enough.

hmm.. you are using 2.6 and im using 2.5
Maybe you could try installing the 2.5 package to see if it helps?
apt-get install python2.5-qt4-gui
Edit: Scratch that, I don't think it would make any difference... hmm
Im afraid I dont know enough to help you out with this one..
If you just type "python" at the n900 terminal, do you get the python info returned? You might just need reinstall the pyqt package again...

To show attila for a third time now:
http://talk.maemo.org/showpost.php?p...7&postcount=45
Install from App Manager instead of Apt-get like I suggested.. it has benefits.

[GCC 4.2.1] on linux2
I installed now with apt-get install python2.5-qt4-gui and my software was running 100%
Is there anyway do make a package from my software ?

Ok, here's a quick tutorial on creating your first app and connecting some signals. The OP shows you how to set everything up so this is going to assume you already have Qt Designer and pyuic4 setup correctly. Screenshots are from the Ubuntu Virtual Machine with the SDK.. but same logic would apply to windows or anything.
So here we go, open up QT designer and create a Main Window:
Lets set the Main Window size to 800x400:
Now we want to create a "Quit" menu item just to show how they work later on in python code.
Now, using the widget selector screen
We click and drag 2 ListWidgets, on either side of the Main Window, and then 5 pushbuttons and a LineEdit in between them. I named the two listWidgets "listRight", and "listLeft" as so:
Using the same screens, I named the buttons:
"btnAdd", "btnAllAdd", "btnRemove", "btnAllRemove", "btnAddNew" and the LineEdit to "lineNew".
Because I like to make things expandable to fit the screen (in case it needs to be resized or is run on something other than a static 800x400 window), we are going to do some grouping too (this is all just for show case). So we add a vertical spacer widget select all the buttons in the middle with the Line Edit and do a Layout Vertically, as so:
Then add two Vertical Spacer widgets to the top and bottom, select them all, and do a layout vertically again.
Now add the Horizontal Spacer widgets shown above to either side, right click on the background Main Window page, and do a "Layout in a Grid". What we end up with is:
Now we're done with QT Designer! So we want to save, and I called it "list_example.ui":
This gives us a standard QT .ui file which would normally be used by a C++ app. But we want python code, so, doing what the OP and every other tutorial tells us to we use pyuic4:
That gives us new python file. Unfortunately, we can't run that file directly as all it is is the GUI - we need to launch it somehow, so we create the main python app and I called it "list_example.py" with the following code:
Now we can run list_example.py directly. If it's on the N900, use "python list_example.py", if you're in the SDK/Scratchbox and want to see it show up properly in Xephyr you use "run-standalone.sh python list_example.py" and voila! We get:
But, of course, nothing works! So we close out and decide we want those buttons to actually do something. We know we have 5 buttons, and 1 menu item, so we know we are going to need 6 connects. So lets try some:
Now, we've connected all 6 items to something. But python has no idea what the things like "self.doAdd" and "self.doAllAdd" are. The only one of those connects that will work is the last one for the "Quit" menu item because we connected it to a built-in qt "quit" slot.
So, now we create various functions (also called methods) that correspond to the names we connected the buttons to:
So, we put it all together and we have (without the above comments):
And our final application:
Yay, not the most useful app.. this is entirely just a "look, it works".. leave it up to you guys to make something useful.
I don't know if anyone will actually *find* any of this any more/less useful than other tutorials.. but maybe some of the images can be used for whoever does the wiki article.
So here we go, open up QT designer and create a Main Window:
Lets set the Main Window size to 800x400:
Now we want to create a "Quit" menu item just to show how they work later on in python code.

This gives us a standard QT .ui file which would normally be used by a C++ app. But we want python code, so, doing what the OP and every other tutorial tells us to we use pyuic4:
Code:
pyuic4 -o list_example_ui.py list_example.ui
Code:
#!/usr/bin/python2.5
import sys
from PyQt4 import QtGui,QtCore
from list_example_ui import *
class MyForm(QtGui.QMainWindow):
def __init__(self, parent=None):
#build parent user interface
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
if __name__ == "__main__":
#This function means this was run directly, not called from another python file.
app = QtGui.QApplication(sys.argv)
myapp = MyForm()
myapp.show()
sys.exit(app.exec_())
Now we can run list_example.py directly. If it's on the N900, use "python list_example.py", if you're in the SDK/Scratchbox and want to see it show up properly in Xephyr you use "run-standalone.sh python list_example.py" and voila! We get:

class MyForm(QtGui.QMainWindow):
def __init__(self, parent=None):
#build parent user interface
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
#connect buttons
QtCore.QObject.connect(self.ui.btnAdd, QtCore.SIGNAL('clicked()'), self.doAdd)
QtCore.QObject.connect(self.ui.btnAllAdd, QtCore.SIGNAL('clicked()'), self.doAllAdd)
QtCore.QObject.connect(self.ui.btnRemove, QtCore.SIGNAL('clicked()'), self.doRemove)
QtCore.QObject.connect(self.ui.btnAllRemove, QtCore.SIGNAL('clicked()'), self.doAllRemove)
QtCore.QObject.connect(self.ui.btnAddNew, QtCore.SIGNAL('clicked()'), self.doAddNew)
QtCore.QObject.connect(self.ui.actionQuit, QtCore.SIGNAL('triggered()'), QtGui.qApp, QtCore.SLOT('quit()'))
So, now we create various functions (also called methods) that correspond to the names we connected the buttons to:
Code:
#Create Sub's
def doAdd(self):
add = 1
for i in range(self.ui.listRight.count()): #let's not create duplicates, so lets do a search.
if self.ui.listRight.item(i).text() == self.ui.listLeft.currentItem().text():
add = 0
if add: #Okay, it wasn't found. Let's add it.
self.ui.listRight.addItem(self.ui.listLeft.currentItem().text())
def doAllAdd(self): #This ones easy, just clear the right one, go through all the left items and add them.
self.ui.listRight.clear()
for i in range(self.ui.listLeft.count()):
self.ui.listRight.addItem(self.ui.listLeft.item(i).text())
def doRemove(self): #Easy again, just remove the selected item.
self.ui.listRight.takeItem(self.ui.listRight.currentRow())
def doAllRemove(self): #Super Easy.
self.ui.listRight.clear()
def doAddNew(self): #Pretty easy, just add to the left what is in the text box, then clear it out.
self.ui.listLeft.addItem(self.ui.lineNew.text())
self.ui.lineNew.clear()
Code:
#!/usr/bin/python2.5
import sys
from PyQt4 import QtGui,QtCore
from list_example_ui import *
class MyForm(QtGui.QMainWindow):
def __init__(self, parent=None):
#build parent user interface
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
#connect buttons
QtCore.QObject.connect(self.ui.btnAdd, QtCore.SIGNAL('clicked()'), self.doAdd)
QtCore.QObject.connect(self.ui.btnAllAdd, QtCore.SIGNAL('clicked()'), self.doAllAdd)
QtCore.QObject.connect(self.ui.btnRemove, QtCore.SIGNAL('clicked()'), self.doRemove)
QtCore.QObject.connect(self.ui.btnAllRemove, QtCore.SIGNAL('clicked()'), self.doAllRemove)
QtCore.QObject.connect(self.ui.btnAddNew, QtCore.SIGNAL('clicked()'), self.doAddNew)
QtCore.QObject.connect(self.ui.actionQuit, QtCore.SIGNAL('triggered()'), QtGui.qApp, QtCore.SLOT('quit()'))
#Create Sub's
def doAdd(self):
add = 1
for i in range(self.ui.listRight.count()):
if self.ui.listRight.item(i).text() == self.ui.listLeft.currentItem().text():
add = 0
if add:
self.ui.listRight.addItem(self.ui.listLeft.currentItem().text())
def doAllAdd(self):

Thanks fatalsaint.
I need to turn my pseudocode into Python for my twitter idea (http://talk.maemo.org/showthread.php?t=37458), and everything in this thread should get me to the next point.
