The Airports method creates a new window and shows a list of nearly all airports. The widget provides several functions:
Search for an airport with the entry at the top of the widget.
The return values are the codes for the airports. In list context a list with one code per element is returned, in scalar context a string is returned with "; " as delimiter.
The Airports method creates a widget object. This object supports the configure and cget methods described in Tk::options which can be used to enquire and modify the options described above. The widget also inherits all the methods provided by the generic Tk::Widget class.
The following additional behavior is defined by the default bindings:
Start the search via <Return> in the Entry at the top of the widget.
Return the selected values via <Return> in the listbox.
Return one selected value via double-clicking the entry in the listbox.
Please contact me when you have found a bug.
