Delete appointments with empty summaries. Fixes Ximian bug #780.
2001-10-27 Federico Mena Quintero <federico@ximian.com> * gui/e-day-view.c (e_day_view_on_editing_stopped): Delete appointments with empty summaries. Fixes Ximian bug #780. * gui/e-week-view.c (e_week_view_on_editing_stopped): Likewise. * gui/dialogs/delete-comp.c (delete_component_dialog): Added an argument to specify whether we unconditionally want single components to be considered as not having a summary. * gui/comp-util.c (cal_comp_confirm_delete_empty_comp): New function. * gui/misc.[ch]: New files with miscellaneous utility functions; moved string_is_empty() over from calendar-model.c. * gui/calendar-model.c: Use the string_is_empty() function from misc.c. * gui/Makefile.am (evolution_calendar_SOURCES): Added misc.[ch] to the list of sources. svn path=/trunk/; revision=14233

+ *
+ * Assumming a calendar component with an empty SUMMARY property (as per
+ * string_is_empty()), asks whether the user wants to delete it based on
+ * whether the appointment is on the calendar server or not. If the

+ * dialog and delete the component if the user tells it to. If the component
+ * is not on the server it will just return TRUE.
+ *
+ * Return value: A result code indicating whether the component
+ * was not on the server and is to be deleted locally, whether it
+ * was on the server and the user deleted it, or whether the
+ * user cancelled the deletion.
