20.10. Program: Displaying Weather Conditions
The gtk-weather.php program shown in Example 20-2 uses SOAP and a weather web service to display weather conditions around the world. It incorporates a number of GTK widgets in its interface: menus, keyboard accelerators, buttons, a text entry box, labels, scrolled windows, and columned lists.
To use gtk-weather.php, first search for weather stations by typing a search term in the text-entry box and clicking the Search button. Searching for weather stations is shown in Figure 20-4.
Figure 20-4. Searching for weather stations
Once you’ve retrieved a list of weather stations, you can get the conditions at a specific station by selecting the station and clicking the Add button. The station code and its current conditions are added to the list at the bottom of the window. You can search again and add more stations to the list. The gtk-weather.php window with a few added stations is shown in Figure 20-5.

The web service this program uses is called GlobalWeather ; look for more information about it at http://www.capescience.com/webservices/globalweather/index.shtml.
