From 277ddb9abe16ba5627f8979faac838ef988b8d3c Mon Sep 17 00:00:00 2001 From: Ettore Perazzoli Date: Fri, 24 Aug 2001 21:06:29 +0000 Subject: New struct `View'. Replace `uri_to_control' in `EShellViewPrivate' with * e-shell-view.c: New struct `View'. Replace `uri_to_control' in `EShellViewPrivate' with `uri_to_view'. (view_new): New. (hash_forall_destroy_view): New, replacing `hash_forall_destroy_control'. (destroy): Updated to match the uri_to_control -> uri_to_view changes. (socket_destroy_cb): Likewise. (get_view_for_uri): Renamed from `get_control_for_uri'. Return a View instead of a GtkWidget. (show_existing_view): Updated to use `get_view_from_uri', get a @view instead of a @control. (e_shell_view_display_uri): Updated to use `uri_to_view' instead of `uri_to_control'. (e_shell_view_remove_control_for_uri): Likewise. svn path=/trunk/; revision=12457 --- shell/ChangeLog | 18 ++++++ shell/e-shell-view.c | 151 +++++++++++++++++++++++++++++++-------------------- 2 files changed, 110 insertions(+), 59 deletions(-) diff --git a/shell/ChangeLog b/shell/ChangeLog index b8c641d670..c1df4d31b3 100644 --- a/shell/ChangeLog +++ b/shell/ChangeLog @@ -1,3 +1,21 @@ +2001-08-24 Ettore Perazzoli + + * e-shell-view.c: New struct `View'.
