[PyQt] QImage displays arbitrary data
Hello all, I am using the python wrapper for opencv, and want to display an opencv image (Swig wrapped CvMat) in a PyQt Widget. To achieve this I create a QImage and wrap it in a Widget-Subclass. The shown Image has correct size but the data shown is corrupted. I create the QImage, with the constructors: QImage.__init__ (self, str data, int width, int height, Format format) or QImage.__init__ (self, str data, int width, int height, int bytesPerLine, Format format) CvMat has a string property imageData, which contains the data. From the OpenCv Docs: the usual data layout of a color image is: b0 g0 r0 b1 g1 r1 ... I know blue and red are switched, but nevertheless it should display the image correctly except for the colors. I have attached a minimal example debug.py. A screenshot of the two Windows (left opencv-highgui, right qt) is also attached. Any help is appreciated, Felixattachment: screenshot.pngfrom PyQt4 import QtGui from PyQt4 import QtCore from opencv.cv import * from opencv.highgui import * import sys class ImageViewWidget(QtGui.QWidget): def __init__(self, qimage): QtGui.QWidget.__init__(self) self.image = qimage def paintEvent(self, event): painter = QtGui.QPainter(self) painter.drawImage(0,0,self.image) if __name__ == __main__: app = QtGui.QApplication(sys.argv) img = cvCreateImage(cvSize(320, 200), IPL_DEPTH_8U, 3) cvSet(img, (128,0,0)) cvLine(img, cvPoint(5,5), cvPoint(315,195), (0,0,255), 5) cvLine(img, cvPoint(315,5), cvPoint(5,195), (0,255,0), 3) cvNamedWindow(a) cvShowImage(a, img) qimg = QtGui.QImage(img.imageData, img.width, img.height, img.step, QtGui.QImage.Format_RGB888) ivw = ImageViewWidget(qimg) ivw.show() app.exec_() ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Re: [PyQt] Next Releases
Hi,
I found the method I was looking for. It is QSslSocket.supportsSsl(). (It is a
static method)

Is there a way to test, if Qt and/or PyQt were built with SSL support.
Overe
here I get strange errors on a Win system. My QSsl... imports work
fine
(i.e.
no ImportError is raised). However, executing this code
from PyQt4.QtNetwork import QSslConfiguration.
sslCfg = QSslConfiguration.defaultConfiguration()
caList = sslCfg.caCertificates()
print len(caList)
prints '0' to the console, while it prints '81' on my Linux box. This
makes
me
assume, that Qt on win is not compiled with SSL support by default (I
used
the standard win installer for Qt 4.5.1 from Nokia).
If there is no programmatic way to do this, would it be possible to
add
a
method to QSslConfiguration (e.g. isAvailable()) that tells, if SSL
support
is available. I think this could be done with some handwritten code
using
something like this.
QSslConfiguration::isAvailable() {
#ifndef QT_NO_OPENSSL
return true;
#else
return false;
#endif
The imports would fail if there was no SSL support. It just looks like
the
certificate database is empty.

I thought so as well. However, trying to connect to a site via https
results
in a bunch of error messages from Qt printed in the console.

QSslSocket: cannot call unresolved function SSL_CTX_new
QSslSocket: cannot call unresolved function SSL_library_init
QSslSocket: cannot call unresolved function ERR_get_error

and the result is an error page being displayed in QWebView telling me,
that
the URL could not be loaded (Reason: HTTP request failed).
All this made me believe, that SSL support is not there.
That would imply that a DLL was missing, or not on the PATH. I don't know
how the Qt installer is built. My builds use static libraries.

[PyQt] QWidget.winEvent and PyQt4.QtCore.MSG
Hi there, i have overwritten a QWidget's winEvent() function because i want to receive a message from another application, which sends it to my application using SendMessage (win32, winapi black magic). winEvent() gets called as expect with one argument, PyQt4.QtCore.MSG. The problem that i am having is that i do not know how to get the type of the received message and its data. Any advice on how to do that or another way how i can listen for windows messages? regards, lg ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] QTreeView Windows cell resizing issue
I have a QTreeView with custom widgets in it and I use the 'resizeColumnsToContents' and 'resizeRowsToContents' functions to correctly size all the cells. This works correctly on Linux but not on Windows.. I am using v4.5-snapshot-20090409 which is a bit old now but I cannot see anything in the change logs related to this anyway. Also, is there anyway to disable user-resizing of the columns and rows? Cheers ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
