2005-04-04 Tor Lillqvist <tml@novell.com> * gdk/win32/gdkmain.c (_gdk_win32_cf_to_string): New debugging function, to log a clipboard format name symbolically. (_gdk_win32_data_to_string): Also new, to log random data bytes. Implement delayed rendering on Win32, specifically for transfering images through the clipboard from GTK+ apps to other apps (#168173, implementation by Ivan Wong): * gdk/win32/gdkevents-win32.c (gdk_event_translate): Handle WM_RENDERFORMAT. * gdk/win32/gdkprivate-win32.h * gdk/win32/gdkglobals-win32.c: Add _format_atom_table, _delayed_rendering_data and _image_bmp. * gdk/win32/gdkmain-win32.c: Initialize _image_bmp. * gdk/win32/gdkproperty-win32.c (gdk_property_change): Accept formats other than GDK_TARGET_STRING or _utf8_string, and assume they are handled through delayed rendering. * gdk/win32/gdkselection-win32.c (gdk_selection_convert): Return all available formats (including those registered by GTK+ apps) on request_targets. (gdk_selection_property_get): We should append a zero byte like X11 does. (gdk_win32_selection_add_targets): New function, for gtkselection's use. Win32 requires that the clipboard owner registers all valid formats even if the owner wants delayed rendering. (_gdk_win32_selection_convert_to_dib): New function. Convert images to DIB using gdk-pixbuf. * gdk/win32/gdkwin32.h: Declare gdk_win32_selection_add_targets(). * gtk/gtkselection.c (gtk_selection_add_target, gtk_selection_add_targets): Call gdk_win32_selection_add_targets() to register target formats. * gdk/gdk.symbols: Add gdk_win32_selection_add_targets().
