Sync to Wine-20050419: Krzysztof Foltman <wdev@foltman.com> - removed trailing spaces from some files - tab support - indent support - PageUp key support. - Support for "normal" scroll bar functionality (line and page scrolling). - made string operations consistent wrt whitespace handling (which should greatly improve stability of the wrap code and eliminate regressions of the most recent versions) - completely new scrollbar handling (much more reliable) and related redraw fixes - Page Down handler (no Page Up yet, fixing wrap/redraw/scrollbar bugs was of higher priority) - RTF reader doesn't use RichEdit messages anymore (which saves on unnecessary repaints) - added unicode character support to RTF import (like: \u12345 ?) - small fixes - fixed whitespace identification bug - removed drawing of paragraph marks - improved stub implementations for IRichEditOle - Unknown destinations are now correctly skipped (so loading an RTF file generated by, for example, OpenOffice doesn't produce lots of garbage anymore). - Format stack for RTF groups (so that RTF reader can correctly read what RTF writer wrote :) ) - EM_STREAMIN can now deal with undo in a reasonable manner (no multiple undo actions in one EM_STREAMIN). - Related changes to undo code (umIgnore mode is now handled correctly). - Numerous improvements in the RTF reader: it reads some character attributes now (you will have proper small print in license agreements now). - Fixed a memory overwrite bug in conversion from CHARFORMAT2A to CHARFORMAT2W. - Optimized repaint of the area below the text. - ME_JoinRuns didn't mark the paragraph for rewrapping, fixed. - Removed PostQuitMessage(0) from WM_DESTROY handler (duh!). - Use of EM_GETOLEINTERFACE is reported with FIXME instead of TRACE (any app using this message is likely to encounter major problems). - WM_COPY (and WM_CUT) can now put both Unicode and RTF format (thanks to Phil Krylov's RTF generator code). - New message implemented - WM_PASTE. - RTF reader: rtfPlain implemented (kind of). - RTF writer: rewritten main loop (the old one crashed in some circumstances when SFF_SELECTION was used). - The meaning of the rewrap flag got inverted (MEPF_REWRAP instead of MEPF_WRAPPED) for consistency. - Major code cleanups in rewrap/repaint code, leading to "smarter" behaviour wrt repainting selections. - Old font management replaced by the cache-based one, which keeps maximum of 10 HFONTs at once, instead of one per a couple of runs. - EM_CANPASTE implemented - updated TODO list (including list of (un)implemented messages) - fixed WM_PASTE (the previous version might not close the clipboard if it didn't contain a usable format) - scrollbar operations (like clicking on arrows) should update scrollbar's current position Gerald Pfeifer <gerald@pfeifer.com> - Make ME_ArrowLeft() return a value in every case. Phil Krylov <phil@newstar.rinet.ru> - Make RTF reader fall back to simple text if a correct RTF header is not detected. This should fix some installers. - Made RTF reader and writer handle codepages mostly similar to the original riched20.dll. - Fixed support for RTF documents using ANSI charset and added support for multibyte charsets, so that BIG5 and UTF-8 RTF documents are working now. - Replaced slow and outdated character set handling in RTF reader by Unicode/codepages support. Added charset->codepage conversion. - Implemented hash table lookup for RTF keywords in RTF reader. - Added "generator" RTF destination handling. - Initial implementation of EM_STREAMOUT and RTF writer. - Fixed \u keyword to output signed 16-bit values. Also fixed CP_SYMBOL conversion and the detection of the default font's codepage. - Improved RTF export. Mike McCormack <mike@codeweavers.com> - Remove casts and unused code.

Sync to Wine-20050725: Phil Krylov <phil@newstar.rinet.ru> - Added some useful TRACEs. - Allow NULL parameter for WM_SETTEXT in RichEdit. - Implemented EM_LINELENGTH RichEdit message. - Fixed EM_LINEINDEX handler and added EM_LINEFROMCHAR handler. - Implemented EM_EXLINEFROMCHAR, EM_LINEINDEX, EM_FINDTEXT, EM_FINDTEXTW, EM_FINDTEXTEX, and EM_FINDTEXTEXW messages. - Fixed a comment about EM_STREAMIN. - Implemented EM_GETLINECOUNT RichEdit message. - Fixed EM_GETCHARFORMAT for selection containing a single character. - Fixed an off-by-one error in EM_GETLINECOUNT handler. - Fixed an off-by-one error in EM_STREAMOUT handler for non-Unicode plain text output. - Fixed another couple of EM_STREAMOUT bugs. - Removed junk from UTF-8 RTF output. - Added emulation of RichEdit 1.0 behaviour when the 1.0 window class is being used. This emulation (introduced in M$ RichEdit 3.0) counts paragraph endings as 2 characters (CR+LF) instead of 1 (CR). - Added EM_GETZOOM and EM_SETZOOM RichEdit message handlers. - Added some missing but useful items to the TODO list.

Sync to Wine-20050419: Krzysztof Foltman <wdev@foltman.com> - removed trailing spaces from some files - tab support - indent support - PageUp key support. - Support for "normal" scroll bar functionality (line and page scrolling). - made string operations consistent wrt whitespace handling (which should greatly improve stability of the wrap code and eliminate regressions of the most recent versions) - completely new scrollbar handling (much more reliable) and related redraw fixes - Page Down handler (no Page Up yet, fixing wrap/redraw/scrollbar bugs was of higher priority) - RTF reader doesn't use RichEdit messages anymore (which saves on unnecessary repaints) - added unicode character support to RTF import (like: \u12345 ?) - small fixes - fixed whitespace identification bug - removed drawing of paragraph marks - improved stub implementations for IRichEditOle - Unknown destinations are now correctly skipped (so loading an RTF file generated by, for example, OpenOffice doesn't produce lots of garbage anymore). - Format stack for RTF groups (so that RTF reader can correctly read what RTF writer wrote :) ) - EM_STREAMIN can now deal with undo in a reasonable manner (no multiple undo actions in one EM_STREAMIN). - Related changes to undo code (umIgnore mode is now handled correctly). - Numerous improvements in the RTF reader: it reads some character attributes now (you will have proper small print in license agreements now). - Fixed a memory overwrite bug in conversion from CHARFORMAT2A to CHARFORMAT2W. - Optimized repaint of the area below the text. - ME_JoinRuns didn't mark the paragraph for rewrapping, fixed. - Removed PostQuitMessage(0) from WM_DESTROY handler (duh!). - Use of EM_GETOLEINTERFACE is reported with FIXME instead of TRACE (any app using this message is likely to encounter major problems). - WM_COPY (and WM_CUT) can now put both Unicode and RTF format (thanks to Phil Krylov's RTF generator code). - New message implemented - WM_PASTE. - RTF reader: rtfPlain implemented (kind of). - RTF writer: rewritten main loop (the old one crashed in some circumstances when SFF_SELECTION was used). - The meaning of the rewrap flag got inverted (MEPF_REWRAP instead of MEPF_WRAPPED) for consistency. - Major code cleanups in rewrap/repaint code, leading to "smarter" behaviour wrt repainting selections. - Old font management replaced by the cache-based one, which keeps maximum of 10 HFONTs at once, instead of one per a couple of runs. - EM_CANPASTE implemented - updated TODO list (including list of (un)implemented messages) - fixed WM_PASTE (the previous version might not close the clipboard if it didn't contain a usable format) - scrollbar operations (like clicking on arrows) should update scrollbar's current position Gerald Pfeifer <gerald@pfeifer.com> - Make ME_ArrowLeft() return a value in every case. Phil Krylov <phil@newstar.rinet.ru> - Make RTF reader fall back to simple text if a correct RTF header is not detected. This should fix some installers. - Made RTF reader and writer handle codepages mostly similar to the original riched20.dll. - Fixed support for RTF documents using ANSI charset and added support for multibyte charsets, so that BIG5 and UTF-8 RTF documents are working now. - Replaced slow and outdated character set handling in RTF reader by Unicode/codepages support. Added charset->codepage conversion. - Implemented hash table lookup for RTF keywords in RTF reader. - Added "generator" RTF destination handling. - Initial implementation of EM_STREAMOUT and RTF writer. - Fixed \u keyword to output signed 16-bit values. Also fixed CP_SYMBOL conversion and the detection of the default font's codepage. - Improved RTF export. Mike McCormack <mike@codeweavers.com> - Remove casts and unused code. Hannu Valtonen <Hannu.Valtonen@hut.fi> - Added mousewheel support. Vincent Beron <vberon@mecano.gme.usherb.ca> - Use "" for Windows includes in dlls, instead of <>.
