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.

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. A default entry is also assigned.

In this example we use a frame widget to generate a visual frame to encapsulate the displayed widget. In addition we used a global variable to pass the variable around to potential functions which could use the variable. Combo boxes allow for a selection of assigned options.

Like all other widgets, it must be assigned to a layout widget to be displayed. Note that the variable "md" is not attached to a layout widget or any other entity in the application. It is not required to "show " the widget either. It stands alone and can be placed anywhere in the code as a mechanism to present a message to the user. Any bitmap image gif, jpeg, etc can be converted to an "xpm" file using image manipulation software such as XV or Gimp and performing a "Save as XPM is a "C" text string representation of a color bit mapped image.

Graphic software conversion typically prepares the XPM in this mode to be embedded into "C" programs. It must be changed from a "C" char to a Python string. It has pages of comprehensive information.

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. In other words, it is a container. Windows normally have decorations that are under the control of the windowing system and allow the user to manipulate the window.
