Wed Dec 7 14:52:25 1994 Alexandre Julliard (julliard@lamisun.epfl.ch) * [controls/listbox.c] Fixed problems due to new scroll-bar code. * [loader/signal.c] [miscemu/ioports.c] Handle I/O opcodes that use an absolute address. * [objects/text.c] Implemented TabbedTextOut(). Sat Dec 3 18:53:08 1994 Kenneth MacDonald <K.MacDonald@ed.ac.uk> * [objects/metafile.c] Implemented GetMetafile(). Fixed bug in PlayMetaFile() when reading disc based metafile records. Added META_POLYPOLYGON, META_DELETEOBJECT and META_EOF to PlayMetaFileRecord(). Wed Nov 30 06:32:25 1994 Martin von Loewis (martin@cs.csufresno.edu) * [Imakefile] wine.sym: Remove gcc2_compiled and friends * [controls/listbox.c][if1632/relay.c][if1632/relay.c] [loader/resource.c][memory/heap.c][objects/dib.c][windows/dialog.c] Replace #ifdef DEBUG_XXX with if(debugging_xxx){ * [if1632/call.S] CallToLibMain: New function * [if1632/relay.c][include/options.h][misc/main.c] [miscemu/int1a.c][miscemu/int21.c][miscemu/kernel.c] removed Options.relay_debug * [include/heap.h] HEAP_OWNER: Use ds instead of cs:ip * [loader/ne_image.c] LoadNEImage: Remember current exe, handle nodata dlls InitNEDLL: handle nodata dlls, call CallToLibMain * [loader/selector.c] CreateSelectors: Initialize auto_data_sel with 0 * [memory/heap.c] HEAP_CheckHeap: Check prev HEAP_CheckLocalHeaps: new function * [misc/profile] Remember and dump only changed profiles * [tools/makedebug] Introduce debugging_xxx flags Sun Nov 27 23:13:22 MET 1994 <erik@xs4all.nl> * [clipboard.h color.h dc.h dos_fs.h event.h font.h graphics.h if1632.h kernel.h library.h miscemu.h ne_image.h nonclient.h pe_image.h selectors.h wintypes.h] Added. * [*/*] - Commented all 'static char copyright statements', see misc/main.c - moved prototypes to headers files, fixed wrong prototypes. - *please* add a header file for each .c if you need to export things. * [misc/main.c] Added one static string which list the names of the contributors. Fri Nov 25 16:24:27 MET 1994 Dag Asheim (dash@ifi.uio.no) * [Configure] Made the support for multiple languages more automatic. Added a [fonts] section to the wine.conf file. Made the defaults better. Generally cleaned it up. * [rc/sysres_No.rc] [rc/sysres_De.rc] [rc/sysres.c] Norwegian resources and small fixes to the german resources. Wed Nov 23 20:28:59 1994 Martin von Loewis (martin@cs.csufresno.edu) * [debugger/break.c] bark(), toggle_next(), should_continue(): New functions insert_break(): Fixed, adds write access to page before writing wine_bp.next_addr: new structure field * [debugger/dbg.y] Changed symbol's value to be it's value instead of the value pointed to by the symbol. Changed SIGTRAP handling to allow continuation after break point * [misc/shell.c] ShellAbout(): Load resource from memory
