forked from AuroraMiddleware/gtk
Mon Jul 3 14:24:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_draw): Ignore calls with <= width or height. * gtk/gtktable.c (gtk_table_attach): Fix missed merge from 1.2 for parent/child states. * gdk/gdkgc.c (gdk_gc_set_rgb_fg/bg_color): Fix a couple of typos. * gdk/gdkevents.[ch]: Remove press/xtilt/ytilt fields of event structures, replace with a generic axes field. Replace deviceid/source with GdkDevice *device. * gdk/gdkevents.[ch] (gdk_event_get_axis): Add function to extract particular axis use value from event. (Also can be used for normal X/Y.) * gdk/gdkinput.h gdk/x11/gdkinput*: Major revision; allow for arbitrary number of axes, namespace everything as gdk_device_*. Replace guint32 deviceid with GdkDevice * everywhere. * gdk/x11/{gdkmain-x11.c,gdkevent-x11.c,gdkinput*}: Get rid of the gdk_input_vtable setup if favor of simply defining the functions in gdkinput-none/gxi/xfree.c in a similar fashion to the way that the port structure is done. * gtk/gtkdnd.c: Fix fields of synthesized button press event for new event structures. * gtk/gtkinputdialog.c gtk/testinput.c: Revise to match new device interfaces.
