It is also possible 11to give credits to the authors, documenters, translators and artists who have 12worked on the program. An about dialog is typically opened when the user selects 13the @samp{About} option from the @samp{Help} menu. All parts of the dialog are 14optional. 15 16About dialog often contain links and email addresses. @code{<gtk-about-dialog>} 17supports this by offering global hooks, which are called when the user clicks on 18a link or email address, see @code{gtk-about-dialog-set-email-hook} and 19@code{gtk-about-dialog-set-url-hook}. Email addresses in the authors, 20documenters and artists properties are recognized by looking for 21@samp{<user@@host>}, URLs are recognized by looking for @samp{http://url}, with 22@samp{url} extending to the next space, tab or line break. 23 24To make constructing a @code{<gtk-about-dialog>} as convenient as possible, you 25can use the function @code{gtk-show-about-dialog} which constructs and shows a 26dialog and keeps it around so that it can be shown again. 27 28@section Usage 29@include defuns-gtkaboutdialog.xml.texi 30 31@c %end of fragment 32
