From 88c6bf4d473d73c03000621f69a16c9c8617cd5b Mon Sep 17 00:00:00 2001 From: Ettore Perazzoli Date: Thu, 11 Jul 2002 19:28:00 +0000 Subject: Remove some `#if 0'ed broken code. New members title_icon and * e-shell-folder-title-bar.c: Remove some `#if 0'ed broken code. New members title_icon and title_button_icon in struct EShellFolderTitleBarPrivate. Remove member icon_widget. New static global variable empty_pixbuf. (init): Initialize these new members to NULL. Don't initialize icon_widget anymore since it's gone. (e_shell_folder_title_bar_construct): Create the title_button_icon and pack it into the title_button_hbox. Also, create the title_icon and pack that one as well. Retouched some of the hardcoded padding values. (size_allocate_icon): Rewritten to use the title_icon and return the allocated space like size_allocate_navigation_buttons. (e_shell_folder_title_bar_set_icon): Remove bogus const from the @icon arg. Ref the pixbuf, and update the two pixmap widgets from it. If @icon is NULL, use the empty_pixbuf. (impl_destroy): Renamed from destroy(). (realize): Removed. (unrealize): Removed. (impl_size_allocate): Renamed from size_allocate(). (class_init): Call it. (add_icon_widget): Removed. (new_empty_pixbuf): New. (new_empty_pixmap_widget): New. (size_allocate_navigation_buttons_and_title_icon): Renamed from size_allocate_navigation_buttons; set up the title_icon too. * e-shell-view.c (update_folder_title_bar): Unref the folder_icon after using it. * e-icon-factory.c (e_icon_factory_get_icon): Ref the returned pixbuf. svn path=/trunk/; revision=17419 --- shell/e-shell-folder-title-bar.c | 266 +++++++++++++++------------------------ 1 file changed, 102 insertions(+), 164 deletions(-) (limited to 'shell/e-shell-folder-title-bar.c') diff --git a/shell/e-shell-folder-title-bar.c b/shell/e-shell-folder-title-bar.c index 7e90e9bbce..f1fef8c68b 100644 --- a/shell/e-shell-folder-title-bar.c +++ b/shell/e-shell-folder-title-bar.c @@ -46,27 +46,30 @@ static GtkHBox *parent_class = NULL; struct _EShellFolderTitleBarPrivate { GdkPixbuf *icon; - GtkWidget *icon_widget; - /* We have a label and a button.
