Python: Popular GUI Frameworks | Intellipaat

There are several popular Python GUI toolkits. The most popular are as follows:

1. Qt
2. GTK
3. wxPython
4. Tkinter

1. Qt

One of the most widely used libraries for cross-platform programming is Qt. It serves as the KDE desktop's primary graphics library. The primary licenses are for commercial and open-source use, while there are more licenses available. You must purchase a license in order to utilize a closed-source, commercial application. The GPL can be used with open-source software, but you can't make your program commercially viable without changing the licence.

It has a graphical layout tool that enables users to drag and drop graphic widgets for quick interface design. The interface layout can, however, be manually coded by the developer. Additionally, it provides non-GUI functions including XML parsing, network support, and SQL database access. Although it is written in C++, PyQt has a Python binding.

2. GTK+

The GIMP Tool Kit, also known as GTK, was developed for the GIMP picture software. The GNOME desktop is managed by the graphics library known as GTK+. A GUI application's fundamental building pieces are widgets.

Under the terms of the GPL, GTK+ is open source. Trolltech owned the Qt licence at the time it was chosen to power the KDE desktop. GTK was developed to allow individuals to utilise the GNOME desktop and GTK apps as open-source software because doing otherwise violates the idea of free software.

GTK doesn't actually come with a drag-and-drop interface built in, but the wxGlade tool adds this feature. The first version of GTK was created in C, while GTK+ was created utilising OOP techniques in C++, and PyGTK was the

3. wxPython

It is a cross-platform toolkit used to create desktop graphical user interface (GUI) applications. It is a wxWidgets implementation in Python, which means that Python programmes communicate with Python wrappers of the core C and C++ code. Developers can construct apps for Mac OS, Windows, and many Unix systems using wxPython.

A general-purpose, cross-platform C++ library is wxWidgets. wxPython is free software that complies with the GNU General Public License. Widgets that are native to an OS are used by programs created in wxPython.

4. Tkinter

The Tk GUI toolkit has a Python binding for it. Due to Tk's inclusion in the base Python language, it is the standard GUI library for Python programming. The Tcl language's initial GUI library is this one. Despite being very limited, the Tkinter toolset is simple to use and may be used to create straightforward GUI apps in Python.

There are three internal layout managers in it:

• Manage widgets in both vertical and horizontal boxes with the pack geometry manager.
• Grid geometry manager: Use a two-dimensional grid to arrange widgets
• Use the absolute positioning feature of the place geometry manager to place widgets on their containers.

JPython: A Combination of java and python

Jim Hugunin has coded it entirely in Java. Python programmers can leverage their Python knowledge in Java-based development environments, while Java programmers can use Python as a tool to govern their Java systems, test libraries, etc.

1. What is Jython?

Jython, which literally translates as "Java Plus Python," refers to creating Python code while using Java code or writing Java code in a Pythonic manner (Python syntax). However, as we will discover in a moment, it is much more than that. Jython, like Python or Ruby, is a general-purpose dynamic scripting language. Additionally, it uses the same syntax as Python, such as the block symbol being represented by ":" and indentation rather than "." Jython is technically a different type of JVM-based language, similar to Scala or Groovy. In a nutshell, Jython is a scripting language that runs on the JVM and has Python support for its syntax and libraries.

2. Jython interpreter/compiler

Although the interpreter and compiler are combined into a single binary, Jython features an interpreter for interactive programming and a compiler for compiling and running the Jython source code. The Jython interpreter/compiler is essentially a large jar file running on JVM, named "jython.jar," regardless of whether "jython.sh" under Unix/Linux or "jython.bat" under Win/Dos is invoked. It interprets and compiles the Jython code into bytecode running on this JVM.

The JPython installation includes a number of parts:

• jpython: Similar to the Python program
• Jpythonc: A JPython application is purchased, and it is afterward converted into Java class files. The Java class files that are produced can be utilized as any other Java class file. for instance, as beans or servlets.
• A collection of modules giving JPython users access to the vast majority of the modules in the common Python library.
