How to properly generate forms in PyQt?

Question

Python

Hello!
I use QtDesigner to draw GUI. Using the pyuic utility, I distill this into Python code. In general, everything is as usual. But after converting to python, everything breaks on the form.
Here is the form in QtDesigner.

And here is the form after the pyuic transformation:

The size of the window has changed, and the menu has disappeared behind the arrow.
Here is the code for the .ui file

<?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>400</width>
    <height>300</height>
   </rect>
  </property>
  <property name="windowTitle">
   <string>MainWindow</string>
  </property>
  <widget class="QWidget" name="centralWidget">
   <widget class="QPlainTextEdit" name="txbx_text">
    <property name="geometry">
     <rect>
      <x>3</x>
      <y>0</y>
      <width>391</width>
      <height>251</height>
     </rect>
    </property>
    <property name="readOnly">
     <bool>true</bool>
    </property>
    <property name="plainText">
     <string/>
    </property>
   </widget>
  </widget>
  <widget class="QMenuBar" name="menuBar">
   <property name="geometry">
    <rect>
     <x>0</x>
     <y>0</y>
     <width>400</width>
     <height>21</height>
    </rect>
   </property>
   <widget class="QMenu" name="menu">
    <property name="title">
     <string>Файл</string>
    </property>
    <addaction name="mnu_open"/>
   </widget>
   <widget class="QMenu" name="menu_2">
    <property name="title">
     <string>Лог</string>
    </property>
    <addaction name="mnu_export"/>
    <addaction name="mnu_add_log"/>
    <addaction name="mnu_view"/>
   </widget>
   <addaction name="menu"/>
   <addaction name="menu_2"/>
  </widget>
  <widget class="QStatusBar" name="statusBar"/>
  <action name="mnu_open">
   <property name="text">
    <string>Открыть</string>
   </property>
  </action>
  <action name="mnu_export">
   <property name="text">
    <string>Экспорт</string>
   </property>
  </action>
  <action name="mnu_add_log">
   <property name="text">
    <string>Добавить в лог</string>
   </property>
  </action>
  <action name="mnu_view">
   <property name="text">
    <string>Просмотр</string>
   </property>
  </action>
  <action name="actionDsfsdf">
   <property name="text">
    <string>dsfsdf</string>
   </property>
  </action>
 </widget>
 <layoutdefault spacing="6" margin="11"/>
 <resources/>
 <connections/>
</ui>

And this is the code for the .py ui file:

PS Of course, I understand that you can dig into the Python form code, but is it possible to somehow automate this process? So that the form immediately appears correctly.
Thanks in advance

Answer 1

In order not to dig, it’s better to write yourself ..
if you decide, here is a link of good lessons, though on PyQt5
