Qt Signals and Slots with Qt Designer

[JeffMGreg]

I'm using Qt Designer to make a simple widget with a QGraphicsView in it. My problem is when I write the main program and try to use the QGraphicsView from the gui file, I can't get any events.
Here's an example of what I'm trying to do. This code is generated from Qt Designer:

from PyQt4 import QtCore, QtGui
 
try:
    _fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
    _fromUtf8 = lambda s: s
 
class Ui_graphicsViewWidget(object):
    def setupUi(self, graphicsViewWidget):
        graphicsViewWidget.setObjectName(_fromUtf8("graphicsViewWidget"))
        graphicsViewWidget.resize(400, 300)
        graphicsViewWidget.setMouseTracking(True)
        self.graphicsView = QtGui.QGraphicsView(graphicsViewWidget)
        self.graphicsView.setGeometry(QtCore.QRect(70, 40, 256, 192))
        self.graphicsView.setObjectName(_fromUtf8("graphicsView"))
 
        self.retranslateUi(graphicsViewWidget)
        QtCore.QMetaObject.connectSlotsByName(graphicsViewWidget)
 
    def retranslateUi(self, graphicsViewWidget):
        graphicsViewWidget.setWindowTitle(QtGui.QApplication.translate("graphicsViewWidget", "Form", None, QtGui.QApplication.UnicodeUTF8))

from PyQt4 import QtCore, QtGui

try:
    _fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
    _fromUtf8 = lambda s: s

class Ui_graphicsViewWidget(object):
    def setupUi(self, graphicsViewWidget):
        graphicsViewWidget.setObjectName(_fromUtf8("graphicsViewWidget"))
        graphicsViewWidget.resize(400, 300)
        graphicsViewWidget.setMouseTracking(True)
        self.graphicsView = QtGui.QGraphicsView(graphicsViewWidget)
        self.graphicsView.setGeometry(QtCore.QRect(70, 40, 256, 192))
        self.graphicsView.setObjectName(_fromUtf8("graphicsView"))

        self.retranslateUi(graphicsViewWidget)
        QtCore.QMetaObject.connectSlotsByName(graphicsViewWidget)

    def retranslateUi(self, graphicsViewWidget):
        graphicsViewWidget.setWindowTitle(QtGui.QApplication.translate("graphicsViewWidget", "Form", None, QtGui.QApplication.UnicodeUTF8))

This is my part of the code:

#!/usr/bin/python -d
 
import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from gui import Ui_graphicsViewWidget
 
class MyForm(QMainWindow):
 
    def __init__(self, parent=None):
        QWidget.__init__(self, parent)
        self.ui = Ui_graphicsViewWidget()
        self.ui.setupUi(self)
        self.ui.graphicsView.setFocus(True)
 
    def mousePressEvent(self, event):
        print("mouse pressed")
 
 
if __name__ == "__main__":
    app = QApplication(sys.argv)
    myapp = MyForm()
    myapp.show()
    sys.exit(app.exec_())

#!/usr/bin/python -d

import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from gui import Ui_graphicsViewWidget

class MyForm(QMainWindow):

    def __init__(self, parent=None):
        QWidget.__init__(self, parent)
        self.ui = Ui_graphicsViewWidget()
        self.ui.setupUi(self)
        self.ui.graphicsView.setFocus(True)

    def mousePressEvent(self, event):
        print("mouse pressed")


if __name__ == "__main__":
    app = QApplication(sys.argv)
    myapp = MyForm()
    myapp.show()
    sys.exit(app.exec_())

Basically what I want here is when I click on the QGraphicsView, I want to capture the mousePressEvent and print something.
I've tried everything I can think of and searched all over the wed, still can't find a solution.

I can accomplish this by writing the whole gui out by hand but I want to know how to do this with Qt Designer.

Thanks for your help.
