gtk/gdk/win32/gdkprivate-win32.h
Tor Lillqvist 1b7cff4755 Apply the same fixes and improvements as to the gtk-1-3-win32-production 
2002-01-10  Tor Lillqvist  <tml@iki.fi>

	Apply the same fixes and improvements as to the
	gtk-1-3-win32-production branch: Bug fixes and cleanup of
	selection and DND functionality. Still doesn't work as well as the
	win32-production branch, though, but getting closer.

	After this, need to add Archaeopteryx Software's OLE2 DND support.

	* gdk/win32/gdkselection-win32.c (gdk_selection_owner_set,
	gdk_selection_send_notify, generate_selection_notify): Don't use
	SendMessage() to generate events for the same app, instead use
	gdk_event_put().

	* gdk/win32/gdkprivate-win32.h
	* gdk/win32/gdkglobals-win32.c
	* gdk/win32/gdkmain-win32.c
	* gdk/win32/gdkevents-win32.c: Thus, remove declaration, definition,
	initialisation and handling of gdk_selection_notify_msg,
	gdk_selection_request_msg and gdk_selection_clear_msg.

	* gdk/win32/gdkselection-win32.c (gdk_text_property_to_text_list,
	gdk_free_text_list, gdk_string_to_compound_text,
	gdk_free_compound_text): Implement trivially, witrh a text_list
	always having a single element, and a compound text always
	consisting of just a single (UTF-8!) string. Let's see how well
	this works.

	* gdk/win32/gdkselection-win32.c (gdk_selection_convert): Fix
	non-ASCII paste from the clipboard: Try getting the same formats
	from the Windows clipboard that gdk_property_change() puts there:
	CF_UNICODETEXT, UTF8_STRING or CF_TEXT+CF_LOCALE.

	* gdk/win32/gdkproperty-win32.c (gdk_property_change): When
	storing text on the clipboard, handle non-ASCII text
	correctly. The logic is as follows:

	If we have only ASCII characters, use CF_TEXT.

	Else, if we are on NT, use CF_UNICODETEXT.

	Else (we are on Win9x), if all the characters are present in the
	code page of some installed locale, use CF_TEXT and also set
	CF_LOCALE to that locale.

	Else (still on Win9x) store as RTF. We use a very simple RTF
	string, just the text, no fonts or other crap, with the non-ASCII
	characters as Unicode \uN keywords. Additionally, also store the
	UTF-8 string as such, under the format "UTF8_STRING", so that GDK
	can also paste from the Clipboard what it has copied there. (Thus
	no need to implement any RTF parser.)

	(find_common_locale): New function, implements the search for a
	locale for case 3 above.

	* gdk/win32/gdkglobals-win32.c: New global variables
	compound_text, text_uri_list, utf8_string, cf_rtf and
	cf_utf8_string.

	* gdk/win32/gdkim-win32.c (_gdk_ucs2_to_utf8): New function,
	converts from a wchar_t string to UTF-8.
	(_gdk_utf8_to_ucs2): Rename from _gdk_win32_nmbstowchar_ts.
	(_gdk_utf8_to_wcs): Rename from gdk_nmbstowchar_ts.

	* gdk/win32/gdkevents-win32.c (build_keypress_event): Use
	_gdk_ucs2_to_utf8().

	* gdk/win32/gdkselection-win32.c: Remove some unnecessary logging.

	* gdk/win32/gdkdnd-win32.c: Plug memory leaks, the
	gdk_drag_context_ref() was called unnecessarily in a couple of
	places, meaning drag contexts were never freed. The same memory
	leaks seem to be present in gdk/linux-fb/gdkselection-fb.c, BTW.

	(gdk_drop_reply): For WIN32_DROPFILES drops, free the temporarily
	stored file list.

	* gdk/win32/gdkselection-win32.c: Clarify the use of the
	sel_prop_table. Now it is used only for storing the GDK_SELECTION
	"properties".

	The file names dropped with WM_DROPFILES -style DND is stored
	temporarily (between the drop and the target picking them up) in a
	separate place.

	Have a separate hash table to map selection atoms to owner
	windows. This used to be quite mixed up.

	(_gdk_dropfiles_store): New function, to store the dropped file
	list for the drop target to possibly fetch, and clear it
	afterwards, from gdk_drop_reply().

	(gdk_selection_owner_get): Much simplified now.
