PyQtgraph Graph in Native Window

Dedicating a UI file to store the application layout will make for a more organized process when working with PyQt. The Python code will be cleaner if it focuses on creating the dynamic data that will be inserted into the ui file.

To demonstrate this, create a window.ui file.

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>MainWindow</class>
 <widget class="QMainWindow" name="MainWindow">
  <property name="windowTitle">
   <string>MainWindow</string>
  </property>
  <widget class="QWidget" name="centralwidget">
     <layout class="QVBoxLayout" name="verticalLayout">
     </layout>
  </widget>
 </widget>
</ui>

Make a Portable Desktop Application without the need for Installation

To create a binary which can be run on many Linux machines, an AppImage can be generated. An AppImage wraps around the files needed to run the application and when executed, doesn't require modifications to your operating system as it is self-contained.

Download the appimage tool executable file from here.

With dearpygui, there are two ways to create a menu bar that displays within your main application window. One method of creating a menu bar is to use the "Viewport Menu Bar" which is the traditional menu bar with the fixed horizontal row of menu entries found near the top of your main applications window and the other is the "Menu Bar" which is a floating menu window inside your main application window.
