QStyledItemDelegate.paint ignores styles?

If I override the paint method of QStyledItemDelegate and call the 
base case, then the base case seems to ignore styles.  I thought that 
the whole point of QStyledItemDelegate was that it handled styles 
correctly? PyQt4.QtCore.QT_VERSION_STR is '4.6.2' and 
PyQt4.QtCore.PYQT_VERSION_STR is '4.7.2'.  I'm also on Ubuntu 10.04.2 LTS.

A minimal example illustrating the problem follows.  If
override_paint == 0, then I see the styles, but if I set it to 1 or 2, 
the effects of the styles disappear.

######################################################################
# change this
override_paint = 0 # 0 or 1 or 2

import sys
from PyQt4 import QtCore, QtGui

class TestDelegate(QtGui.QStyledItemDelegate):
     if override_paint == 1:
         def paint(self, painter, option, index):
             QtGui.QStyledItemDelegate.paint(self, painter, option, index)

     if override_paint == 2:
         def paint(self, painter, option, index):
             super(TestDelegate, self ).paint(painter, option, index)

app = QtGui.QApplication(sys.argv)

# Make tableview
tableView = QtGui.QTableView()
tableView.setStyleSheet("""QTableView::item { padding: 10px;
                                               background-color: blue;
                                              }""")

# Make delegate
delegate = TestDelegate(tableView)
tableView.setItemDelegate(delegate)

# Make the model
model = QtGui.QStandardItemModel(4, 2)
for row in range(4):
     for column in range(2):
         index = model.index(row, column, QtCore.QModelIndex())
         model.setData(index, "\n".join(["(%i, %i)" % (row, column)]))
tableView.setModel(model)

tableView.show()
sys.exit(app.exec_())
#############################################################################

Is this a bug or am I missing something?  Thanks for any info.

This does eliminate the error trying to link the plugin. The --arch
arguments force universal binaries with support for both 32- and
64-bit apps, which is fine, however I do note during the configure of
PyQt the following appears:

> QtDesigner module disabled with universal binaries.

I wasn't planning to use QtDesigner anyway, so no big.

BTW: running the full PyQt make with an epic number of g++ compiles on
a macbook pro? Runs the CPU temps up to full-fan and makes it quite
uncomfortable to have on one's lap!

Connect PyQt signal to C++ slot

I will describe the general task I am performing beforehand as there may
be better way to do it than I am currently trying.

I am making a Python editor and console using Qt. This includes a
QScintilla editor and a QTextEdit for terminal output. I want to "pipe"
stdout and stderr from the Python interpreter to the terminal as the
Python program is executed by the interpreter.

I currently run the program using the Py_Initialize(),
PyRun_SimpleString(), Py_Finalize() paradigm. I am able to print stdout
and stderr to the console after the Python program has finished by
assigning a Python class to sys.stdout and sys.stderr which has a string
member that is later extracted using PyObject_GetAttrString after the
Python program finishes. This is done using PyRun_SimpleString() and a
bit of hard-coded Python in the C++ class invoking the Python
interpreter.

However I want output from the program to be appended to the terminal as
it is printed to stdout and stderr, not at the end of the program. My
idea for this was to make the Python class assigned to sys.stdout and
sys.stderr inherit from QObject, and emit a signal whenever output
occurs. I can emit this signal when output occurs with a QString
containing the message as an argument, but I don't know how to connect
the PyQt signal to a C++ slot from within the C++ class that is invoking
the Python interpreter.

Is this even possible? And if so, what functions (I suspect in sip.h)
should I use? It looks like I would use sipConvertFromNewType to wrap
the class with the slot with a PyObject, and then sipConnectRx to
connect the signal to the slot that appends to the terminal.

Thank you.

Do it like you would call any Python method from C++. Get hold of the
signal's connect method using appropriate PyObject_GetAttr calls and call
one of the PyObject_Call functions.

nmake fatal error while compiling SIP - voidptr.c: error C2039

Hello,

I am trying to compile SIP since a few days in order to install PyQt.
I can't find lead on the web so I thought I'd better ask for help here.

I unzipped the latest sip archive (4.12.1)and run the configure command.
Then when I tried to run nmake it gives me the following error :

.\voidptr.c(513) : error C2039: 'obj' : is not a member of 'bufferinfo'
D:\ProgramFiles\Python26\include\object.h(164) : see declaration of 'bufferinfo'
Generating Code...
NMAKE : fatal error U1077: '"D:\ProgramFiles\Microsoft Visual Studio 9.0\VC\bin\cl.EXE"' : return code '0x2'
Stop.
NMAKE : fatal error U1077: '"D:\ProgramFiles\Microsoft Visual Studio 9.0\VC\bin\nmake.exe"' : return code '0x2'
Stop.

The declaration of bufferinfo in object.h is the following :

typedef struct bufferinfo {
    void *buf;        
        Py_ssize_t len;
        Py_ssize_t itemsize;  /* This is Py_ssize_t so it can be
                                 pointed to by strides in simple case.*/
        int readonly;
        int ndim;
        char *format;
        Py_ssize_t *shape;
        Py_ssize_t *strides;
        Py_ssize_t *suboffsets;
        void *internal;
} Py_buffer;

And the code at line 513 of voidptr.c is :

PyErr_Format(PyExc_TypeError, "'%s' must have an item size of 1",
                Py_TYPE(value_view.obj)->tp_name);

I am on windows XP 64bits, with Python 2.6 and visual studio 2008 (I run the commands from visual studio
command prompt).

Thank you for you consideration.

Johanna

How do I subclass QTextEdit without warnings on close?

Hello,

I am trying to subclass QTextEdit to implement a foucsOutEvent.  I must be 
doing something wrong however because when I replace the standard QTextEdit 
with my subclass I get the following error mesages when I close the program.  
(once for each instance of my subclass). I don't when a reqular QTextEdit is 
used.

Application asked to unregister timer 0x6000001 which is not registered in 
this thread. Fix application.
Application asked to unregister timer 0x3d000002 which is not registered in 
this thread. Fix application.

I running on Fedora 14 and my versions numbers are:
Python: 2.7
Qt: 4.7.2
PyQt: 4.8.3
sip: 4.12.1

Can anyone tell me what I'm doing wrong?

Below is a simple program to demonstrate my error:

########################################

from PyQt4 import QtCore, QtGui

try:
    _fromUtf8 = QtCore.QString.fromUtf8

    textEdited = QtCore.pyqtSignal('QString')

    def __init__(self, *args):
        QtGui.QTextEdit.__init__(self, *args)

    def  focusOutEvent(self, e):
        val = self.toHtml()
        self.textEdited.emit(val)

class frmTest(QtGui.QMainWindow):
    def __init__(self, app, *args):

        self.teDesc2 = MyQTextEdit(self.mainWidget)
        self.teDesc2.setObjectName(_fromUtf8("teDesc1"))

That's not the declaration from Python v2.6.

Maybe you are using a 2.6 beta?
