Tue Feb 3 15:34:27 1998 Owen Taylor <owt1@cornell.edu> * gdk/gdkcolor.c (gdk_colormap_get_system): Only query the colormap for GRAYSCALE and PSEUDOCOLOR visuals, and don't ask for more than 256 colors in any case. * gdk/gdkwindow.c (gdk_window_internal_destroy): Remove the input window information when we destroy the window, not when we are notified of it. * gdk/gdkinputcommon.h (gdk_input_device_new): Work around bug in XFree86 3.3.1's handling of Wacom macro buttons. by assumming no device will report exactly 25 buttons. * gdk/gdkinputcommon.h (gdk_input_common_other_event): Fill in string translation for generated key press events, do sanity checking on received key codes. * gdk/gdkcc.c (gdk_color_context_new): Allocate enough room for a GdkColorContextPrivate, not just for a GdkColorContext.
