RE: [PyQt] QSqlQueryModel works but QSqlTableModel doesn't work
I don't think that are the permissions, anyway I tried to log in as root and I still have the same problem. I'm using mysql and connecting to it trought QODBC. All the other tables works well!

It seems something related to the status of table. Do you have the permission to read the table? Which database are you using?

Hello all
I've run into a problem wrapping a subclass of Qt 3's QSettings. The
problem is that QSettings' copy constructor is private and SIP wants
to copy construct an instance of my class. How can I solve this?
What are the circumstances in which SIP wants to create the instance?
This is the generated code at least: http://pastebin.com/m64228e27.
I can't reproduce this. The simple attached test does the right thing.

Seems like there is: ... virtual void polish ( QWidget * widget ) virtual void polish ( QApplication * application ) virtual void polish ( QPalette palette ) ... virtual void unpolish ( QWidget * widget ) virtual void unpolish ( QApplication * application ) ... so SIP-level conversion code between QWidget,QApplication and QPalette should be there? (or maybe i'm totally wrong) Wrong. If you reimplement polish() in Python then you need to check the type of the argument to work out overload has been called. Something like... def polish(self, arg): if isinstance(arg, QtGui.QPalette): # polish(const QPalette ) reimplementation elif isinstance(arg, QtGui.QWidget): # polish(QWidget *) reimplementation else: # We haven't reimplemented this so call the base class.

[PyQt] PyKDE-3.16.1 release
A new PyKDE3 release is up at Riverbank Computing: http://www.riverbankcomputing.co.uk/pykde/index.php This release removes the need to patch the PyKDE3 source code, and should also remove any of the konsole_part issues some people were having (konsole_part is no longer supported). The release also requires a sip version of 4.7.0 or later (preferably the most recent release - 4.7.4 - which is also available at Riverbank). I've decided to upgrade PyKDE3 to the latest KDE releases, through 3.5.9. The current release should build against any PyKDE3 released version, and there probably isn't a lot of new stuff in the more recent KDE releases.

[PyQt] PyKDE4-4.0.0 release available
The first PyKDE4 tarball release is available at Riverbank Computing http://www.riverbankcomputing.co.uk/pykde/index.php This release will build against KDE 4.0.0 or 4.0.1 (the difference between the two is a total of 3 new methods). With the exception of a couple of small bug fixes, this release should be the same as the kdebindings releases that come with KDE4, maintained by Simon Edwards. This release includes a full set of documentation based on the C++ documentation included in the KDE4 h files. It also includes a tutorial and a few small example programs. It also includes a framework for viewing live examples and documentation simultaneously (pykdedocs), based on the pykdesampler Troy Melhase began for PyKDE3. The documentation, examples and viewer can be installed separately if you already have PyKDE4 installed. The viewer requires PyKDE4. Contributions of additional example programs or tutorials would be greatly appreciated. Jim ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Hi,
I'm trying to write a program that creates an onscreen keyboard that uses an
2-analogue stick joypad for input. I'm having issues becuase the joystick
needs to be polled regularly. I'm using a QTimer to call a paintEvent
update() that polls the joystick in the main class (Keyboard). However
there's some other drawing i want to do when the joystick is polled. However
the drawing is supposed to be done by a different class with its own
graphics etc (called Ring), and i found the only way that seemed to work was
to put the drawing i want to do in the paintEvent of that class and both
seem to get called. But this seems kinda weird, and for some reason if i
simply called the drawing to be done by Ring as a method of the Ring object
in the paintEvent of Keyboard it doesn't work.
I'm sorry if there's a bit confusing, i'm very new to programming and QT and
also asking questions on mailing lists.
Basically doing
Class keyboard()
...
self.timer.start(50)
self.connect(self.timer, QtCore.SIGNAL('timeout()'), self, QtCore.SLOT
('update()'))
...
def paintEvent()
...poll the joystick
Class Ring()
...
def paintEvent()
... do the ring drawing
works, but doing
Class keyboard()
...
self.timer.start(50)
self.connect(self.timer, QtCore.SIGNAL('timeout()'), self, QtCore.SLOT
('update()'))
...
def paintEvent()
...poll the joystick
...ring.drawstuff()
Class Ring()
...
def drawstuff()
... do the ring drawing
Just lands me with a blank window.
Hope someone can help explain this.
thanks

I think the correct thing to do would have a slot connected to the timer that polls the joystick then calls ring.update(). You should generally avoid having any code in the paintEvent except for actual painting code. And you should call paintEvent on the widget that actually needs repainting.

However the drawing is supposed to be done by a different class with its own graphics etc (called Ring) I know this isn't the main point of your questions. But the paintEvent Function you are overriding should only deal with painting. It doesn't Clean to be polling hardwhere during this call. It sounds like the best plan is to create your own method to handle polling the hardware. You can then tell the widget to update if anything has changed. Using the QTimer is the right approach, just have it call your own function that does something like this. def myTimerCallback(self): PollJoysticks() self.ringWidget.repaint() ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] Re: PyQt
Thanks for the speedy responses!
I'm now trying to create a non-paintEvent function that calls an update if
necessary. But now when i do
self.connect(self.timer, QtCore.SIGNAL('timeout()'), self.pollJoysticks())
i get an error: Argument 3 (i.e. the pyFunction call) is of invalid type.
but here (
http://www.riverbankcomputing.com/Docs/PyQt4/pyqt4ref.html#signal-and-slot-support)
It says i should be able to use the form
QtCore.QObject.connect(a, QtCore.SIGNAL(QtSig()), pyFunction)
I know that the timeout signal and my polling function work because they
worked fine before, all i did was rename paintEvent to pollJoysticks and add
a call to the proper paintEvent, and replace
self.connect(self.timer, QtCore.SIGNAL('timeout()'), self, QtCore.SLOT
('update()')
with what i put above.
if i use
self.connect(self.timer, QtCore.SIGNAL('timeout()'), self, QtCore.SLOT
('pollJoysticks()'))
polljoysticks doesn't get called at all. Is there something special i should
put in the pollJoysticks method to make it a Slot?
thanks

Remove the parens from self.pollJoysticks () - you want the address of the
method, not to call the method. Should be:
self.connect ( ... self.pollJoysticks)
