2002-05-11 Anders Carlsson <andersca@gnu.org> * src/display.c: (find_tab_forward), (find_tab_backward), (meta_display_get_tab_next): * src/display.h: * src/keybindings.c: (handle_tab_forward), (handle_focus_previous): Add screen argument to meta_display_get_tab_next, since we only want windows on the same screen to appear in the tab chain. * src/screen.c: (meta_screen_new): Or the event mask with existing events since gtk+ may listen to certain events and we don't want to disable those events. (meta_screen_ensure_tab_popup): * src/tabpopup.c: (meta_ui_tab_popup_new): * src/tabpopup.h: Add a screen number argument to meta_ui_tab_popup_new so we can position the popup on the correct screen.
