    <p>I run a <code>pyqt4</code> application in <code>spyder</code>, I exit with <code>QtGui.QMainWindow.close()</code> and it returns me to the <code>spyder python interpreter</code> prompt. However, if I try and run the application again <code>runfile('C:/Python33/~/qtapp.py', wdir=r'C:/Python33/~/Appdir')</code> The window doesn't show. I have to shut the python interpreter window down and open a new one up before I can run my <code>pyqt4</code> app again. This suggest to me that I am.</p> <ol> <li>Not shutting down the app correctly</li> <li>Not running the app correctly</li> </ol> <p>I want to be able to run the <code>pyqt4</code> app from the same prompt, this would speed up my dev time</p> <p>Here is the example code:</p> <pre><code>from PyQt4 import QtCore, QtGui, Qwt5 import sys try: _fromUtf8 = QtCore.QString.fromUtf8 except AttributeError: def _fromUtf8(s): return s try: _encoding = QtGui.QApplication.UnicodeUTF8 def _translate(context, text, disambig): return QtGui.QApplication.translate(context, text, disambig, _encoding) except AttributeError: def _translate(context, text, disambig): return QtGui.QApplication.translate(context, text, disambig) class Ui_MainWindow(object): def setupUi(self, MainWindow): MainWindow.setObjectName("MainWindow") MainWindow.resize(200, 200) self.checkBox = QtGui.QCheckBox(MainWindow) self.checkBox.setGeometry(QtCore.QRect(100, 100, 70, 17)) self.checkBox.setObjectName("checkBox") self.retranslateUi(MainWindow) QtCore.QMetaObject.connectSlotsByName(MainWindow) def retranslateUi(self, MainWindow): MainWindow.setWindowTitle(QtGui.QApplication.translate("MainWindow", "Dialog",None, QtGui.QApplication.UnicodeUTF8)) self.checkBox.setText(QtGui.QApplication.translate("MainWindow", "CheckBox", None, QtGui.QApplication.UnicodeUTF8)) class MainWindow(QtGui.QMainWindow,Ui_MainWindow): def __init__(self): super(MainWindow, self).__init__() self.setupUi(self) app = QtGui.QApplication(sys.argv) form = MainWindow() form.show() app.exec_() </code></pre> <p>After I run it once the window shows up, after I run it again the window doesn't show up, Here's my version info:</p> <p>Python 3.3.2 (v3.3.2:d047928ae3f6, May 16 2013, 00:03:43) [MSC v.1600 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information.</p> <p>Imported NumPy 1.7.1, SciPy 0.12.0, Matplotlib 1.3.0 + guidata 1.6.1, guiqwt 2.3.1 Type "scientific" for more details.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
