Prior to working through this tutorial, it is recommended that you have a reasonable grasp of the Python programming language. It is necessary for you to know how to create and run Python files, understand basic interpreter errors, and work with strings, integers, floats and Boolean values. For the more advanced widgets in this tutorial, good knowledge of lists and tuples will be needed. Search Page. Installation 2.

If you have never programmed before, or are not familiar with the concepts of object oriented programming, you may need to learn a few basics first. Once you master the basics, be sure to come back and check out these tutorials. Type or copy and paste the code into a file, and save the file with a name like filename. After executing the code, you will either see the widget on your screen, or if you have mistyped some of the code you will see an error message that will help you identify the problem.
The tutorial will walk you through increasingly complex examples and programming theory, but you can also feel free to just go directly to the tutorial that is most helpful to you.

These libraries closely resemble the capabilities of the GTK "C" libraries. All pyGTK layouts are organized in a tree structure with the root of the tree being the main display window. Button widgets provide a mechanism to provide functionality for the user action of selecting the button. Thus the programmer must provide a Python callback function to be executed when the button is pressed. Text entry widgets require a callback function to manage and receive the text. Note that the callback is called initially when the default text is assigned and every time the text entry is changed. In this example we also added a label to display the intent of the text entry box to the user.

In is created in C language. Originally, the library was created while developing the GIMP image manipulation program. In the first application, we display a window on the screen. Window is a toplevel window which can contain other widgets.
