2001-11-28 Federico Mena Quintero <federico@ximian.com> Fixes bug #3290. * e-shell-folder-selection-dialog.c (e_shell_folder_selection_dialog_construct): Use our own filename for the collapsation state of the tree, instead of sharing the one of shell view number 0. (save_expanded_state): New function, saves the collapsation state of the tree. (impl_destroy): Call save_expanded_state(). 2001-11-14 Ettore Perazzoli <ettore@ximian.com> svn path=/trunk/; revision=14820
