Wed Apr 1 00:15:30 1998 Norbert Warmuth <k3190@fh-sw.de> * key.c, key.h (numeric_keypad_mode, application_keypad_mode): New functions which encapsulate two hardcoded escape sequences from main.c. * main.c (main): Use the two new functions from key.c * main.c, screen.c: Moved all file selection keys from the default keymap to the keymap for panels in listing mode. Changed *_selection_cmd to *_selection_cmd_panel in panel_keymap (functions in panel_keymap get a WPanel * as first parameter, i.e. the indirection with cpanel isn't necessary). * main.c (midnight_callback): Keys '*' and '-' were not treated when only_leading_plus_minus==0; Optimized the if-clauses a little bit (i.e. removed duplicate checks). More optimation is possible but it would make the whole stuff completly unreadable. * key.c (correct_key_code): KP_ADD, KP_SUBTRACT and KP_MULTIPLY will be translated to +, - and * only if the option alternate_plus_minus is turned off. * learn.c (learn_keys): Turn alternate_plus_minus temporarily on to avoid translation of KP_ADD, KP_SUBTRACT and KP_MULTIPLY in correct_key_code/make sure keypad is in application mode (makes it possible to learn this keys). * cmd.c (reverse_selection_cmd_panel): New function (renamed from reverse_selection_cmd, takes a WPanel * as parameter, references to cpanel changed to panel/the passed parameter). reverse_selection_cmd now simply calls this function with cpanel. This pair was missing among the *_selection_cmd* functions. * cmd.h: Added function prototypes.

These are a bunch of changes to fix CORBA and session management. They are almost complete (i.e. to handle all nitty gritty cases), but they seem to be working OK right now. SM should be much more stable now. Please tell me if you find any weird behavior - Federico 1999-03-30 Federico Mena Quintero <federico@nuclecu.unam.mx> * gdesktop-icon.c (desktop_icon_realize): Remove the WM_CLIENT_LEADER property from icon windows so that window managers will not store SM information for them. * gnome-open-dialog.c: Added missing #includes. * gdesktop-init.c (desktop_init_at): Removed an unused variable. * gdesktop.h: Added some missing prototypes. * gmain.h: Added some missing prototypes. * Makefile.in: Added gsession.[ch] to the list of sources. * gmain.c (create_panels): Consider whether we have a CORBA server and session management. * gdesktop.c: #include "gdesktop-init.h" * gdesktop.c: Added a missing cast to GNOME_DIALOG. * gmain.c (create_panels): Removed the run_desktop global variable. * glayout.c (create_container): Set the wmclass of the panel to include its unique ID. * gsession.[ch]: New file with the functions that deal with session management. * glayout.c (gnome_exit): Use session_set_restart(). * gcorba.c (corba_init): Now returns an int with an error value. (corba_init_server): Initialize the server properly. Fixed all the object implementation code. (corba_create_window): New function used to create a window with the CORBA server. * gmain.c (gnome_check_super_user): Now the check for running as root is done here. There should be no GUI code in src/. 1999-03-30 Federico Mena Quintero <federico@nuclecu.unam.mx> * dlg.c (dlg_run_done): Do not call the callback of a NULL current widget. * setup.h: Added missing prototype for setup_init(). * filegui.c (check_progress_buttons): Added a missing return value. * dlg.c (remove_widget): Added a missing return value. * main.c: Removed the global directory_list variable. Removed the main_corba_register_server() function. * main.h: Removed the global run_desktop variable. * panel.h: Now the panel structure has a unique numerical ID used for session management. * screen.c (panel_new): Maintain a unique ID for each panel. * main.c (maybe_display_linksdir): Handle display of the desktop init dir here. (main): Call gnome_check_super_user(). (init_corba_with_args): Call corba_init_server(). * main.c (init_corba_with_args): Do CORBA initialization here. Also removed the global force_activation option. 1999-03-30 Federico Mena Quintero <federico@nuclecu.unam.mx> * vfs.c (vfs_add_current_stamps): Only do stamping of the panels if they exist. * mcserv.c: #include <sys/wait.h> (get_client): Put `#ifdef __EMX__' around an otherwise-unused variable. * utilvfs.c (vfs_split_url): Fix NULL <-> 0 confusion when comparing characters. * ftpfs.c (retrieve_dir): Removed unused variable dot_dot_found. * extfs.c (extfs_init): Assign `key' to c, not `&key'.
