* docs/gtk_tut.sgml:
- new section on Events
- change all delete_event callbacks to include
a GdkEvent parameter
- clean up the formatting
* examples - helloworld.c, helloworld2.c, notebook.c,
packbox.c, pixmap.c, progressbar.c, radiobuttons.c,
rulers.c, table.c, wheelbarrow.c: change all delete_event
callbacks to include a GdkEvent parameter.
