<div>I have the piece of code <br clear="all">

<div>
<div> view = QtGui.QGraphicsView(scene)</div>

<div> view.setRenderHint(QtGui.QPainter.Antialiasing)</div>

<div> view.setBackgroundBrush(QtGui.QBrush(pixmap))</div>
<div> view.setCacheMode(QtGui.QGraphicsView.CacheBackground)</div>
<div><br>
</div>
<div>So my scene have 800 x 600 pixel, and my image too. When I try
put the background in view just show a view in white color with no
image. What I 'm doing wrong?</div>

Hi,<br>
<br>
I have reproduce your code like this:<br>
<br>
class GraphicView(object):<br>
def __init__(self, MainWindow):<br>
MainWindow.resize(864, 649)<br>
self.centralwidget = QtGui.QWidget(MainWindow)<br>
self.gridLayout = QtGui.QGridLayout(self.centralwidget)<br>
self.scene = QtGui.QGraphicsScene(self.centralwidget)<br>
self.graphicsView = QtGui.QGraphicsView(self.scene)<br>
self.graphicsView.setRenderHints(QtGui.QPainter.Antialiasing)<br>
pixmap = QtGui.QImage("amymc1.jpg") <br>
self.graphicsView.setBackgroundBrush(QtGui.QBrush(pixmap))<br>
self.graphicsView.setCacheMode(QtGui.QGraphicsView.CacheBackground)<br>
self.gridLayout.addWidget(self.graphicsView, 0, 0, 1, 1)<br>
MainWindow.setCentralWidget(self.centralwidget)<br>
<br>
On Qt 4.6, PyQt 4.7.2<br>
and Qt 4.7, PyQt 4.7.4<br>
<br>
That functions but the result is unexpected.(See attachement)<br>
