I just started two apps with PyKDE this year and am happy with it. Thanks for your work on this. One small question: can we now use the KDE bug tracker for fileing bugs?

[PyQt] Changes in PyKDE
As some of you may have noticed, I haven't been keeping up with PyKDE very well lately (again), but Simon Edwards has. Since I'm unlikely to be able to do much with it for the forseeable future, we've agreed to have Simon take it over. The major change will probably be that up-to-date releases will come via KDE releases (version releases and bugfix releases), and Simon will probably keep you up-to-date on the where and when of those. Any project decisions are now up to Simon. A number of people on this list have made significant contributions to PyKDE over the years, and I really appreciate all of the help, criticism, bug reports and fixes. I'll probably still follow the list and will be happy to answer any questions (although I can't imagine anything that Phil or Simon won't be able to handle better). Thanks again to everyone who has participated in PyKDE. Jim ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

The C++ example code I'm following uses a QMap data structure to hold

dir(QtCore),
and some googling, I've found that QMap is not implemented in
PyQt. So
I'm using a Dict instead. Still, my app complains:
TypeError: invalid result type from DirModel.data()
Here's the C++ code I'm following:
virtual QVariant data(const QModelIndex &index, int role =
Qt::DisplayRole) const
{
if (role == Qt::CheckStateRole && index.column() == 0) {
return
checkstates.value(fileInfo(index).absoluteFilePath(),
Qt::Unchecked);
You need to wrap that in a QVariant, i.e.
return QVariant()
data() needs to return a QVariant and Python doesn't support the
implicit constructors as C++ does.

Re: [PyQt] QDirModel instance
Right. Thanks for pointing out that I still need to explicitly pass
"self."
I'm still not getting checkboxes displayed in the tree widget,
though. I believe the problem is in the nested return value in the
model's data() method.
The C++ example code I'm following uses a QMap data structure to hold
checkState values. After reading Assistant notes, a python
dir(QtCore), and some googling, I've found that QMap is not
implemented in PyQt. So I'm using a Dict instead. Still, my app
complains:
TypeError: invalid result type from DirModel.data()
Here's the C++ code I'm following:
virtual QVariant data(const QModelIndex &index, int role =
Qt::DisplayRole) const
{
if (role == Qt::CheckStateRole && index.column() == 0) {
return
checkstates.value(fileInfo(index).absoluteFilePath(), Qt::Unchecked);
}
return QDirModel::data(index, role);
}
private:
QMap checkstates;
};
Here's my code:
class DirModel(QtGui.QDirModel):
def __init__(self, parent=None):
QtGui.QDirModel.__init__(self, parent)
self.checkstates = {}
def data(self, index, role=QtCore.Qt.DisplayRole):
if (role == QtCore.Qt.CheckStateRole and index.column() == 0):
self.checkstates[self.fileInfo(index).absoluteFilePath()] =
QtCore.Qt.Checked
return self.checkstates[self.fileInfo(index).absoluteFilePath()]
# <-- problem???
return QtGui.QDirModel.data(self, index, role)
Thanks in advance for your suggestions!

Hello,
I just joined this list and am new to PyQt (and Qt). I've scanned
the
archives, but I'm not sure even what I'm looking for to answer my
question.
I'm looking over some C++ code, trying to rewrite it in Python. (My
Spanish is much better than my C++!) I'm sub-classing and extending
QDirModel and getting the following error:
TypeError: first argument of unbound method QDirModel.data() must be
a QDirModel instance
The C++ methods are:
virtual QVariant data(const QModelIndex &index, int role =
Qt::DisplayRole) const
{
if (role == Qt::CheckStateRole && index.column() == 0) {
return
checkstates.value(fileInfo(index).absoluteFilePath(), Qt::Unchecked);
}
return QDirModel::data(index, role);
}
My translation so far looks like this:
[ ... ]
class DirModel(QtGui.QDirModel):
def data(self, index, role=QtCore.Qt.DisplayRole):
if (role == QtCore.Qt.CheckStateRole and index.column() == 0):
return
checkstates.value(fileInfo(index).absoluteFilePath(),
QtCore.Qt.Unchecked)
return QtGui.QDirModel.data(index, role)
[ ... ]
Not sure how to make the first argument (index or self?) be a
QDirModel instance. Ultimately I'm hoping for a directory tree with
check boxes.
Suggestions?
When using an unbound method (including __init__()) you must
explicitly
pass self. So...
return QtGui.QDirModel.data(self, index, role)

[PyQt] pyuic 4.4.2 missing support for QFormLayout?
Hello, all,
I'm running:
$ pyuic4 --version: Python User Interface Compiler 4.4.2 for Qt version 4.4.0
$ dpkg -l pyqt4-dev-tools: 4.4.2-0ubuntu2
and it borks out on the attached .ui file with the following error message:
$ pyuic4 /tmp/test-formlayout.ui
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file '/tmp/test-formlayout.ui'
#
# Created: Thu Jul 10 16:29:00 2008
# by: PyQt4 UI code generator 4.4.2
#
# WARNING! All changes made in this file will be lost!
from PyQt4 import QtCore, QtGui
class Ui_Dialog(object):
def setupUi(self, Dialog):
Dialog.setObjectName("Dialog")
Dialog.resize(269,125)
self.gridLayout = QtGui.QGridLayout(Dialog)
self.gridLayout.setObjectName("gridLayout")
Unknown Qt widget: QFormLayout
Is QFormLayout missing from pyuic, or is something wrong on my end?
Thanks!

[PyQt] Returning a subclass
Greetings, here is the code: class myAction (QtGui.QAction): def __init__ (self, parent, myProperty): QtGui.QAction.__init__ (self, parent) self.myProperty = myProperty Later this myAction is instanced and added to a toolbar someAction = myAction (self, "The Property") self.toolbar.addAction(myAction) Then in the end I want to iterate through all the actions in toolbar: for a in self.toolbar.actions(): print type(a) print a.myProperty toolbar.actions() returns a list of QActions, is there a way to recast this QAction back to myAction? Is the information about subclass lost during this process? First print in the above code will print And the second will raise the AttributeError obviously. Any ideas on this one?
