    <p><strong>SOLVED</strong><br> I changed: </p> <blockquote> <p>self.ui = base_class() </p> </blockquote> <p>Into: </p> <blockquote> <p>self.ui = form_class()<br> self.ui.setupUi(self) </p> </blockquote> <p>And now it works!</p> <hr> <p>I'm trying to get some code working so I can use the .ui file on the fly. This way updates with Qt Designer are immediately used when I run the python code.</p> <p>After fiddling and using snippets I ended up with the following code. But somehow the button in the .ui doesn't show. Anyone an idea?</p> <pre><code>import sys,os from PyQt4 import QtCore, QtGui, uic form_class, base_class = uic.loadUiType('try_ui.ui') class MainWindow(QtGui.QMainWindow): def __init__(self, parent = None): QtGui.QWidget.__init__(self, parent) self.ui = base_class() if __name__ == "__main__": app = QtGui.QApplication(sys.argv) myapp = MainWindow() myapp.show() sys.exit(app.exec_()) </code></pre> <p>And try_ui.ui a simple button:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;ui version="4.0"&gt; &lt;class&gt;MainWindow&lt;/class&gt; &lt;widget class="QMainWindow" name="MainWindow"&gt; &lt;property name="geometry"&gt; &lt;rect&gt; &lt;x&gt;0&lt;/x&gt; &lt;y&gt;0&lt;/y&gt; &lt;width&gt;323&lt;/width&gt; &lt;height&gt;111&lt;/height&gt; &lt;/rect&gt; &lt;/property&gt; &lt;property name="windowTitle"&gt; &lt;string&gt;MainWindow&lt;/string&gt; &lt;/property&gt; &lt;widget class="QWidget" name="centralwidget"&gt; &lt;widget class="QPushButton" name="pushButton"&gt; &lt;property name="geometry"&gt; &lt;rect&gt; &lt;x&gt;120&lt;/x&gt; &lt;y&gt;30&lt;/y&gt; &lt;width&gt;75&lt;/width&gt; &lt;height&gt;23&lt;/height&gt; &lt;/rect&gt; &lt;/property&gt; &lt;property name="text"&gt; &lt;string&gt;PushButton&lt;/string&gt; &lt;/property&gt; &lt;/widget&gt; &lt;/widget&gt; &lt;widget class="QMenuBar" name="menubar"&gt; &lt;property name="geometry"&gt; &lt;rect&gt; &lt;x&gt;0&lt;/x&gt; &lt;y&gt;0&lt;/y&gt; &lt;width&gt;323&lt;/width&gt; &lt;height&gt;21&lt;/height&gt; &lt;/rect&gt; &lt;/property&gt; &lt;/widget&gt; &lt;widget class="QStatusBar" name="statusbar"/&gt; &lt;/widget&gt; &lt;resources/&gt; &lt;connections/&gt; &lt;/ui&gt; </code></pre>

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.
