Overview of this book

Tkinter is the built-in GUI package that comes with standard Python distributions. It is a cross-platform package, which means you build once and deploy everywhere. It is simple to use and intuitive in nature, making it suitable for programmers and non-programmers alike. This book will help you master the art of GUI programming. It delivers the bigger picture of GUI programming by building real-world, productive, and fun applications such as a text editor, drum machine, game of chess, media player, drawing application, chat application, screen saver, port scanner, and many more. In every project, you will build on the skills acquired in the previous project and gain more expertise. You will learn to write multithreaded programs, network programs, database driven programs and more. You will also get to know the modern best practices involved in writing GUI apps. With its rich source of sample code, you can build upon the knowledge gained with this book and use it in your own projects in the discipline of your choice.

Adding top bar options for draw methods

Each of the 16 toolbar buttons can have their own option. Just like we called the functions related to the toolbar buttons dynamically, we will again call methods to display options for the top bar dynamically.

So we decide that the method name for handling the top bar options would be named by appending the string _options to the existing method.

So suppose we want to display the options for the draw_line method, it would be called draw_line_options. Similarly, we have to define methods like draw_arc_options, draw_star_options, and others.

We achieve this dynamic call in the method display_options_in_the_top_bar as follows (see code

    def display_options_in_the_top_bar(self):
        self.show_selected_tool_icon_in_top_bar (self.selected_tool_bar_function)
        options_function_name = "{}_options".format(self.selected_tool_bar_function)
        func = getattr(self, options_function_name, self.function_not_defined)
