Sun Nov 6 18:52:04 1994 Alexandre Julliard (julliard@lamisun.epfl.ch) * [objects/oembitmap.c] (New file) Added possibility to use .xpm files for OEM bitmaps. * [include/bitmaps/obm*] (New files) Redrawn all OEM bitmaps in xpm format. * [objects/font.c] Add space for internal leading when using a negative font height. Stubs for AddFontResource() and RemoveFontResource(). Fix in FONT_Init() for uninitialised default font. * [windows/dialog.c] Make font height negative as it is really a point size and not a pixel size; dialogs using 8-point fonts look better now. * [windows/graphics.c] Fixed the fix :-) for Pie() to make it work for Arc() and Chord() also. * [windows/nonclient.c] A few changes for new OEM bitmaps. Sun Nov 6 18:22:18 1994 Michael Patra <micky@marie.physik.tu-berlin.de> * [windows/class.c] The names of local classes have to be stored using GlobalAtom*. Otherwise they couldn't be accessed from other modules (e.g. BWCC) * [if1632/call.S] CallTo16(cx): It's possible to set the contents of the cx-register. * [loader/ne_image.c] InitNEDLL(): The size of the local heap is now passed in the cx- register when initializing a DLL. * [memory/heap.c] LocalInit(): The case start==0 is now handled in the way it should. * [windows/win.c] GetWindowLong(): If the adress of the windows function is requested it's no longer returned if it's within the Wine code (and therefore unreachable by a windows program). This makes Borland's OWL happy. * [controls/edit.c] EDIT_GetStr(): Added handling for off<0. Sun Nov 6 17:37:14 1994 Chris Jones <chrisj@ichips.intel.com> * [loader/library.c] Fixed infinite loop bug when two DLLs refer to each other (fixes hangup of Quicken during loading). Thu Nov 04 12:00:00 1994 Jan Willamowius (jan@janhh.sh.sub.de) * [misc/dos_fs.c] Bug fix: The size of a disk an the available space is now returned in bytes instead of (incorrectly) KBytes. Thu Nov 03 12:00:00 1994 Jan Willamowius (jan@janhh.sh.sub.de) * [windows/graphics.c] Bug fix: Pie segments are now filled with correct brush. Thu Nov 3 10:40:09 1994 Martin von Loewis (martin@cs.csufresno.edu) * [Imakefile] generate rc.o before loader.o * [controls/menu.c] CopySysMenu: generate SYSMENU on the fly, eliminate hSysMenu * [include/resource.h] Add struct ResourceTable * [loader/bitmap.h] Load system bitmaps from sysresbmTable * [misc/clipboard.c] [windows/event.c] IsClipboardFormatAvailable,EVENT_SelectionRequest: bug fixes * [rc/Imakefile] generate rc.o from sysres.o and sysresbm.o. Added -lfl * [rc/rc.y] change style handling to allow ( S1 | S2 ) | S3 * [rc/sysres.rc] [rc/sysresbm.rc] Put bitmaps and icons to sysresbm, everything else to sysres * [rc/winerc.c] [rc/winerc.h] Added -o, -c flags. New function set_out_file. Output to files. * [windows/dialog.c] DialogBoxIndirectPtr, DialogBoxIndirectParamPtr: New functions * [windows/nonclient.c] Create AboutWine dialog from template pointer
