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.
