[PyQt] uic.loadUi and package argument

[Fredrik Averpil]

Hi,

I’d like to load a .ui file and use a custom widget in it without importing
a package from disk. I’m trying to achieve this like so:

class MyCustomClass(QtWidgets.QPushButton):
    def __init__(self, *args):
        QtWidgets.QPushButton.__init__(self, *args)

sys.modules['mycustompackage'] = MyCustomClass
uic,loadUi('my_ui.ui', self, 'mycustompackage')

However, the error I’m getting is this:

AttributeError: type object 'MyCustomClass' has no attribute 'MyCustomWidget'

Any ideas on whether I can make this work at all - and if so how?

Here’s my .ui:

<?xml version="1.0" encoding="UTF-8"?><ui version="4.0">
 <class>MainWindow</class>
 <widget class="QMainWindow" name="MainWindow">
  <property name="geometry">
   <rect>
    <x>0</x>
    <y>0</y>
    <width>800</width>
    <height>600</height>
   </rect>
  </property>
  <property name="windowTitle">
   <string>MainWindow</string>
  </property>
  <widget class="QWidget" name="centralwidget">
   <widget class="MyCustomWidget" name="customWidget">
    <property name="geometry">
     <rect>
      <x>50</x>
      <y>70</y>
      <width>113</width>
      <height>32</height>
     </rect>
    </property>
    <property name="text">
     <string>PushButton</string>
    </property>
   </widget>
  </widget>
  <widget class="QMenuBar" name="menubar">
   <property name="geometry">
    <rect>
     <x>0</x>
     <y>0</y>
     <width>800</width>
     <height>22</height>
    </rect>
   </property>
  </widget>
  <widget class="QStatusBar" name="statusbar"/>
 </widget>
 <customwidgets>
  <customwidget>
   <class>MyCustomWidget</class>
   <extends>QPushButton</extends>
   <header>MyCustomClass</header>
  </customwidget>
 </customwidgets>
 <resources/>
 <connections/></ui>

Regards,
Fredrik
