2001-10-29 Tor Lillqvist <tml@iki.fi> * gdk/win32/libwntab32x.la: New file, hand-written wrapper for the Wintab library. * gdk/win32/gdkwin32.h * gdk/win32/gdkprivate-win32.h: Reorganise to match corresponding X11 headers better, and to enable gdkwin32.h to be installed and included from applications, but not the *-win32.h headers. * gdk/win32/*.c: Corresponding small changes, simplifications of #includes. * gdk/win32/gdkregion-win32.c: Remove. * gdk/win32/gdkevents-win32.c (print_event): Add GDK_SETTING. * gdk/win32/gdkfont-win32.c * gdk/win32/gdkgeometry-win32.c: Remove unused variables. * gdk/win32/gdkproperty-win32.c (gdk_atom_intern): Don't insert GDK_NONE values into hash table. Changes for autoconfiscated build on Win32, and addition of Win32 backend to the related files: * gdk/win32/Makefile.am: Actually enable building the win32 objects here, not just list all files in EXTRA_DIST. Link in the compiled resource file from rc/gdk-win32res.lo. If HAVE_WINTAB, copy the Wintab library into the .libs directory. * gdk/win32/gdkwindow-win32.c (RegisterGdkClass): Don't assume the name of the GDK DLL when fetching the icon. Use the HMODULE saved in gdk_dll_hinstance by DllMain. * gdk/win32/rc/Makefile.am: Build gdk-win32res.lo using the build/win32/lt-compile-resource script. * gdk/win32/rc/gdk.rc.in * gtk/gtk-win32.rc.in: Use the DLL name that libtool would use.
