Then you create an instance of wx.App(), which is your Application object. Here you import wx, which is how you access wxPython in your code.

Go ahead and create a new file named hello_wx.py and add this code to it: # hello_wx.pyįrame = wx.Frame(parent=None, title='Hello World') To see how this all works, you should create a little 'Hello World' application. Note that when using wxPython, most widgets and attributes are pre-fixed with wx. When you create a frame or dialog, it includes a title bar and the minimize, maximize, and exit buttons. These widgets can contain other widgets, like buttons and labels. You start out with top-level widgets, such as a wx.Frame or a wx.Dialog. Widgets are the building blocks of your application.

Now that you have a basic understanding of event loops, it's time to learn how to write a simple prototype application! How to Create Widgets The user can stop the event loop by exiting the program.

The user does something (clicks a button, etc).

The GUI waits for the user to do something.

The overarching process is called the event loop. Some books call this event-driven programming. Button events are usually connected to wx.EVT_BUTTON, for example. When the user does something like that, the GUI receives an event. Unlike a command-line application, a GUI is basically an infinite loop, waiting for the user to do something, like click a button or press a key on the keyboard. But when it comes to creating GUI programs, you need to understand that they use events to tell the GUI what to do. In the introduction, you learned what widgets are.

Here is the command you would use to install wxPython using pip: python3 -m pip install wxpythonĪssuming everything worked, you should now be able to use wxPython! Learning About Event Loopsīefore you get started, there is one other item that you need to know about. On Mac OSX, you may need the XCode compiler to install wxPython. You can see the most up-to-date set of requirements on the wxPython Github page. If you are installing on Linux, you may need to install some prerequisites before installing wxPython. Installing wxPython is usually done with pip. Note: Some of the examples in this chapter come from my book, Creating GUI Applications with wxPython. However, you will learn enough to see the power of wxPython as well as discover how much fun it is to create a desktop GUI of your very own. This article does not attempt to cover everything there is to know about wxPython. The reason that wxPython was chosen is that the author has more experience with it than any other and wxPython has a very friendly and helpful community. You will be learning about wxPython in this article.

Here is a list of some of the most popular: There are many different GUI toolkits for Python. Collectively, these items are known as 'widgets'. These consist of buttons, text, pictures, tables, and more. The concepts you learn in this article can be applied to mobile and web development to some degree as well.Ī graphical user interface is made up of some kind of window that the user interacts with.

For the purposes of this article, you will learn about creating desktop GUIs. It could be argued that GUIs are also created for mobile and web as well though. The desktop refers to Windows, Linux and MacOS. Graphical user interfaces (GUI) are programs that are usually defined as created for the desktop. However, most beginners do not learn how to create a graphical user interface until much later in their classwork. A lot of students are also starting out by writing front-end programs, which are typically websites written with HTML, JavaScript and CSS.

When you first get started as a programmer or software developer, you usually start by writing code that prints to your console or standard out.
