Working with titles</A></H1><P>When you create a CList widget, you will also get a set of titlebuttons automatically. They live in the top of the CList window, andcan act either as normal buttons that respond to being pressed, orthey can be passive, in which case they are nothing more than atitle. There are four different calls that aid us in setting thestatus of the title buttons.</P><TABLEBORDER="0"BGCOLOR="#E0E0E0"WIDTH="100%"><TR><TD><PRECLASS="PROGRAMLISTING">void gtk_clist_column_title_active( GtkCList *clist,                                     gint     column );void gtk_clist_column_title_passive( GtkCList *clist,                                     gint      column );void gtk_clist_column_titles_active( GtkCList *clist );void gtk_clist_column_titles_passive( GtkCList *clist );</PRE></TD></TR></TABLE><P>An active title is one which acts as a normal button, a passive one isjust a label. The first two calls above will activate/deactivate thetitle button above the specific column, while the last two callsactivate/deactivate all title buttons in the supplied clist widget.</P><P>But of course there are those cases when we don't want them at all,and so they can be hidden and shown at will using the following twocalls.</P><TABLEBORDER="0"BGCOLOR="#E0E0E0"WIDTH="100%"><TR><TD><PRECLASS="PROGRAMLISTING">void gtk_clist_column_titles_show( GtkCList *clist );void gtk_clist_column_titles_hide( GtkCList *clist );</PRE></TD></TR></TABLE><P>For titles to be really useful we need a mechanism to set and changethem, and this is done using</P><TABLEBORDER="0"BGCOLOR="#E0E0E0"WIDTH="100%"><TR><TD><PRECLASS="PROGRAMLISTING">void gtk_clist_set_column_title( GtkCList *clist,                                 gint      column,                                 gchar    *title );</PRE></TD></TR></TABLE><P>Note that only the title of one column can be set at a time, so if allthe titles are known from the beginning, then I really suggest usinggtk_clist_new_with_titles (as described above) to set them. It savesyou coding time, and makes your program smaller. There are some caseswhere getting the job done the manual way is better, and that's whennot all titles will be text. CList provides us with title buttonsthat can in fact incorporate whole widgets, for example a pixmap.
