Hello,
I get a strange error when using QGraphicsView in the way shown below.
The error is:
QObject::startTimer: QTimer can only be used with threads started with QThread
What it leaves me perplex is that the error does not appear if the
getPixmap function is not defined.
As you may notice, the function is not used at all!
This happens with the most recent sip and PyQt4 snapshots as well as with
the december snapshots.
It happens on Qt 4.2.2. and Qt 4.2.3, under linux (tested on 4.2.2) and
under windows (tested with both).
When building PyQt4 for Qt 4.2.3 on windows with mingw, I had to add myself
to the path the libqpydesigner.a library found under
C:\Qt\4.2.3\PyQt-win-gpl-4-snapshot-20070310\qpy\QtDesigner\release. If
not, PyQt4 was not able to finish the build.
Greetings,
Armando
Code follows:
import sys
import PyQt4.Qt as qt
if 1: #if changed to if 0: the error disappears
def getPixmap():
mypixmap = None
return mypixmap
app = qt.QApplication([])
qt.QObject.connect(app, qt.SIGNAL("lastWindowClosed()"),
app,qt.SLOT("quit()"))
widget = qt.QWidget()
l = qt.QVBoxLayout(widget)
scene = qt.QGraphicsScene()
pixmap = qt.QPixmap()
pixmapItem = qt.QGraphicsPixmapItem(pixmap, None, scene)
view = qt.QGraphicsView(scene, widget)
l.addWidget(view)
widget.resize(300, 600)
widget.show()
sys.exit(app.exec_())
