Whenever the slider button is moved across, the "-SL-" event occurs. The instantaneous value of the slider button is used as the font size and the Text caption is refreshed. To confirm that both PySimpleGUIWx and WxPython are properly installed, enter following statements in Python terminal. >>> import PySimpleGUIWx

The output generated by the program should be similar to the one displayed below − Equivalent Tkinter CodeGlobal settings are the application settings available application wide. These settings control the various properties of the Element class to be applied to all the Elements in the application.

Use the dictionary-style [ ] syntax to read a setting. If the item's name is '- item-', then reading the value is achieved by writing The infinite event loop that makes the PySimpleGUI window persistent, is terminated when the user presses the "X" button, or the close() method of Window class is executed.

Used in a group of other Radio Elements to provide user with ability to select only one choice in a list of choices. However, if you want to manipulate the value of an element programmatically, the element must be initialized by assigning a unique string value to its key parameter. The key of an element is like the name of the variable or identifier, which makes it convenient to handle reading or assigning a value to it programmatically. In the following example, a big file zen.txt is displayed in a popup with scrollable text box. The file contains the design principles of Python called the "Zen of Python". In addition to the built-in debugger that most IDEs such as PyCharm or VS Code have, PySimpleGUI offers its own debugger. This debugger provides you the ability to "see" and interact with your code, while it is running.
