Fri Mar 8 19:07:18 1996 Alexandre Julliard <julliard@lrc.epfl.ch> * [configure.in] Quote '[' and ']' in the test program for the strength-reduce bug. This should work much better... * [files/file.c] Augmented DOS_FILE structure. Most internal functions now return a DOS_FILE* instead of a Unix handle. Added a local file array to replace the PDB list upon startup, to allow using file I/O functions before the first task is created. Added FILE_SetDateTime() and FILE_Sync() functions. * [loader/module.c] Use the DOS file I/O functions in MODULE_LoadExeHeader(). * [objects/bitblt.c] Use visible region instead of GC clip region to clip source area. This fixes the card drawing bug in freecell. * [objects/region.c] Fixed CombineRgn() to allow src and dest regions to be the same. Fri Mar 8 16:32:23 1996 Frans van Dorsselaer <dorssel@rulhm1.leidenuniv.nl> * [controls/EDIT.TODO] Updated so it reflects the current status. * [controls/edit.c] Implemented internal EDIT_WordBreakProc(). Implemented ES_READONLY. Implemented WM_LBUTTONDBLCLK to select whole words. Fixed a lot of types in the function definitions. Wed Mar 6 19:55:00 1996 Alex Korobka <alex@phm30.pharm.sunysb.edu> * [debugger/info.c] Added "walk window" command to walk window list. * [windows/mdi.c] Added proper(?) WM_MDISETMENU message handling. Wed Mar 6 09:27:12 1996 Martin von Loewis <loewis@informatik.hu-berlin.de> * [if1632/callback.c][if1632/relay32.c] RELAY32_CallWindowProcConvStruct: new function. * [win32/struct32.c][win32/Makefile.in][win32/param.c][win32/user32.c] struct32.c: new file. Moved all structure conversions into that file PARAM32_POINT32to16,MSG16to32,USER32_RECT32to16: renamed to STRUCT32_POINT32to16, ... WIN32_POINT,WIN32_MSG,WIN32_RECT,WIN32_PAINTSTRUCT: renamed to POINT32, ... New conversion functions for NCCALCSIZE_PARAMS, WINDOWPOS, CREATESTRUCT. * [include/windows.h][misc/exec.c] WINHELP, MULTIKEYHELP, HELPWININFO: new structures WinHelp: Reimplemented. Thanks to Peter Balch (100710.2566@compuserve.com) for his valuable research. * [win32/winprocs.c] WIN32_CallWindowProcTo16: new function, call in USER32_DefWindowProcA,... Mon Mar 4 23:22:40 1996 Jim Peterson <jspeter@birch.ee.vt.edu> * [include/wintypes.h] Added "#define __export". * [objects/bitblt.c] Put in a few hacks to make bitblt-ing work when upside-down and/or mirrored. BITBLT_StretchImage should really be checked over thoroughly. * [programs/progman/main.c] Added "#include <resource.h>" for definition of HAVE_WINE_CONSTRUCTOR. * [rc/parser.h] [rc/parser.l] [rc/parser.y] [rc/winerc.c] Eliminated shift/reduce conflict in style definition. Added crude error message support: "stdin:%d: parse error before '%s'". Implemented string table support to the best of my ability (it works with LoadString() calls). * [windows/nonclient.c] Fixed bug in NC_DoSizeMove() that made system menu pop up when title bar of non-iconized window was clicked (checked for iconization). Mon Mar 04 20:55:19 1996 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de> * [if1632/lzexpand.spec] [if1632/relay.c] [include/lzexpand.h][misc/lzexpand.c] LZEXPAND.DLL added. Sun Mar 03 18:10:22 1996 Albrecht Kleine <kleine@ak.sax.de> * [windows/win.c] Prevent usage of invalid HWNDs in WIN_EnumChildWin(), this prevents too early termination of EnumChildWindows(). |

This is a short discussion of resources in WineLib. Introduction Resources are used to store dialogs, menus, bitmaps, icons, version information, strings, fonts, and accelerators. In a Win3.1 programming environment, there are three file formats for resources: - the RC script, which is human-readable and can be processed by a resource compiler - the .RES file, which is the output of the resource compiler - the .EXE and .DLL files, which store resources as a part of the NE file format For WineLib, only a part of this is supported. In particular, there is no .RES file, the executable is not a NE file (as it is a native Unix executable), and some resource types are not implemented: icons, version information, strings, and fonts. Building a WineLib application The build process assumes that the C source files and the resource script is available. At the moment, a single resource script is recommended. This script is processed by winerc: 1) the preprocessor is used to resolve symbolic style name (LBS_STANDARD, ...) into numbers. This involves processing windows.h 2) the unused parts of windows.h (type definitions) are removed. This would not be necessary if Wine's windows.h would use the RC_INVOKED macro. 3) winerc is invoked to create a binary representation of the resources. This representation is stored as C source code (arrays). 4) gcc is used to compile the generated C code. Now, each resource is available as a C array to the application. As the executable is not in the NE format, it is not possible to retrieve resource locations in the executable via name. Instead, the resources have to be referenced with their generated C array names. The linker then resolves these names in the compiled resource file. 5) The program sources are compiled and linked with the output of step 4. A sample build process is in toolkit/Makefile:hello3. Required changes to the program sources Because loading the resources from an instance handle is not possible, the *Indirect functions have to be used to load a resource. The C arrays can be directly passed to the *Indirect functions. So, instead of writing hMenu=LoadMenu(hInstance,"MAIN"); write hMenu=LoadMenuIndirect(hello3_MENU_MAIN.bytes); Fortunately, the Windows API has the following functions available: DialogBoxIndirect CreateDialogIndirect DialogBoxIndirectParam CreateDialogIndirectParam LoadMenuIndirect SetDIBitsToDevice Sample code is available in hello3.c. hello3res.c contains the corresponding resources. Keeping a common source Clearly, changing the sources is not very desirable, and suggestions how to reduce the amount of work are welcome. In the meantime, two approaches allow at least to remain a common source between the Win3.1 code and the WineLib code: 1) conditional compiles: When compiling a WineLib application, WINELIB is defined. This can be used to select Wine-specific code. 2) usage of winerc for Windows: The *Indirect functions are available on plain Win3.1, and the resource format is fully compatible. Thus, recompiling sources modified for WineLib on Win3.1 is possible and known to work. Open problems 1) Icons and cursors: For these resources, there is no *Indirect function documented. In addition, both are implemented by a set of two resources. This is the reason why they are not supported by winerc. 2) Accelerators: Although winerc supports accelerators, there is no LoadAcceleratorIndirect function. A work-around would be to define one. 3) Fonts: Font resources are not supported by Wine at all. 4) String tables: Although string tables are not supported by winerc, there is no reason not to add such support. Again, some indirect loading would be necessary. 5) API requires loading by name: At some places, the name of a resource is passed instead of a handle. The WNDCLASS structure contains the name of a menu resource, and the icon in a dialog box is referenced by its name. (Are there some more places?) Clearly, loading the resource by name would be highly desirable. The resource compiler currently creates a structure containing all resources defined in an RC file. However, it is not clear how WINELIB could find the location of this structure, especially, when there is more than one RC file.
