Wed Mar 11 15:28:45 1998 Miguel de Icaza <miguel@nuclecu.unam.mx>
* gwidget.c (entry_release): Now the WEntrys track the current
selection.p
(x_update_input): Repaint the widget after changing the position.
* gscreen.c (x_fill_panel): Remember the selected item on the
panel before filling it up, as gtk_clist emits a select_item
signal when filling it up, which changes the current selection
(and thus some routines that invoke the reload panel option
fail).
1998-03-11 Federico Mena Quintero <federico@nuclecu.unam.mx>
* gmc-chargrid.c (gmc_char_grid_get_size): New public function.

Wed Mar 11 19:02:48 1998 Miguel de Icaza <miguel@nuclecu.unam.mx>
* view.c: Lots of changes: Split the X11 code from the main view
program. This is needed to cleanly support the addition of the
Gnome version of the file viewer;
New names for old functions (just a view_ prefix):
view_add_character, view_add_string, view_gotoyx, view_set_color,
view_display_clean. Now all of them take a WView argument (which
is ignored in the macro for the text edition). This is to support
multiple open views at once.
* boxes.c (symlink_dialog): Enable ok/cancel buttons for the Gnome edition.
* cmd.c (link_cmd, symlink_cmd): Provide the filename to operate
on.
Tue Mar 10 20:41:45 1998 Miguel de Icaza <miguel@nuclecu.unam.mx>
* cmd.c (unselect_cmd_panel, select_cmd_panel): To avoid races on
