* configure.in acheader.h gdk/gdkwindow.c
Check for Shape extension both on the client and server
side. (And, more importantly, check for the shape extension
so we may include -lXext even when compiling with --disable-xshm)
Don't set override_redirect on all shaped windows. It isn't
necessary.
* gdk/gdkwindow.c: Set ->colormap to NULL for root
and foreign windows. Use this to check if we
need to get the colormap from X.
Fri May 1 22:32:47 1998 Owen Taylor <otaylor@gtk.org>
* gtk/gtkbutton.c (gtk_button_paint): Draw the areas
between the default and the button always in GTK_STATE_NORMAL.
* gtk/gtkrange.c (gtk_range_style_set): Added a style_set
callback.
Fri May 1 16:40:57 1998 Owen Taylor <otaylor@gtk.org>
* gdk/gdkpixmap.c (gdk_pixmap_colormap_create_from_xpmp[_d]):
Fix a buffer overflow on pixmaps that claim to have
more than 31 characters per pixel.
(gdk_pixmap_read_string): Don't wrap around strings longer
than half of address space ;-)
* gtk/gtk[vh]ruler.c gtk/gtkinputdialog.c: Expand some buffers
that were used for printing integers.
* */* (almost):
Style: All
int foo () { ... }
changed to
int foo (void) { ... }
^^^^^^^ This is why some many files changed
Even where there were proper prototypes elsewhere.
* gdk/gxid.c (handle_claim_device): Some extra checks.
It isn't safe against being fed bad X id's, but at
least it should be safe against deleting all your
files.
