2000-12-06 Alexander Larsson <alexl@redhat.com> * gdk/linux-fb/Makefile.am: Add gdkmouse-fb.c * gdk/linux-fb/gdkmouse-fb.c: New file. Abstracted the mouse drivers a bit. * gdk/linux-fb/gdkcursor-fb.c: The cursor hide/show functions was moved here from gdkinput-ps2.c. * gdk/linux-fb/gdkinput-ps2.c: Removed old mouse handling code. Moved cursor handling code to gdkcursor-fb.c, moved gdk_fb_window_send_crossing_events() to gdkwindow-fb.c. gdk_input_get_mouseinfo was renamed to gdk_mouse_get_info. * gdk/linux-fb/gdkmain-fb.c: Pass NULL pointers for x,y in gdk_mouse_get_info call. * gdk/linux-fb/gdkprivate-fb.h: Removed public gdk_fb_find_common_ancestor, added and renamed functions for the new mouse handling code. * gdk/linux-fb/gdkwindow-fb.c: Moved gdk_fb_window_send_crossing_events here. added global variable gdk_fb_window_containing_pointer. made gdk_fb_find_common_ancestor static. gdk_input_get_mouseinfo was renamed to gdk_mouse_get_info.
