* [configure.in] [Makefile.in] [tools/install-sh]
New 'install' target installs Wine binary, library and man page.
Library is now more logically named libwine.a.
Split toolkit/ directory into library (for library code) and
libtest (for test programs).
* [controls/edit.c]
Quick hack to partially support EM_PASSWORD style (avoids
displaying your passwords on the screen when testing programs...)
* [configure.in] [controls/menu.c] [include/resource.h]
[misc/commdlg.c] [misc/ole2nls.c] [misc/shell.c] [windows/msgbox.c]
Language is now a run-time option (wine -language xx).
* [debugger/dbg.y]
Dump some more debugging info on crash.
* [misc/profile.c]
Only consider ';' as a comment if it's the first non-blank
character on the line.
* [miscemu/dpmi.c]
More debugging info for real-mode callback.
* [objects/gdiobj.c]
Rewrote EnumObjects() to do the Right Thing.

New directory containing system resources.
Fri Dec 22 11:24:39 GMT 1995 John Harvey <john@division.co.uk>
* [win32/file.c] [win32/memory.c]
Unixware doesn't have MAP_ANON ifdefed out for now.
* [misc/dos_fs.c]
DOS_GetDosFileName didn't truncate paths starting ./ properly.
* [tools/build.c]
Produces assembly code that works with the unixware assembler.
Wed Dec 20 22:22:29 +0100 1995 Morten Welinder <terra@diku.dk>
* [miscemu/instr.c]
INSTR_GetOperandAddr: 16-bit addresses should be masked to 16 bits.
* [misc/dos_fs.c]
DOS_readdir should always return directories, even if they don't
match the file name mask.
Tue Dec 19 18:00:00 1995 Uwe Bonnes <bon@elektron.ikp.physik.th-darmstadt.de>
* [misc/exec.c]
Give arguments to winhelp.
* [miscemu/int21.c]
Implemented Interrupt 21 AX=6C00 EXTENDED OPEN/CREATE.
Created function ExtendedOpenCreateFile.
Give for some Windows95 interrupts the return value 'not
implemented'.
Sun Dec 17 16:51:56 EST 1995 Jim Peterson <jspeter@birch.ee.vt.edu>
* [include/kernel32.h] [include/windows.h]
Moved the typedefs for SYSTEMTIME and LPSYSTEMTIME from
include/kernel32.h to include/windows.h and declared the new Win32
API functions Sleep(), GetLocalTime(), and GetSystemTime().
Redefined INFINITE as 0xFFFFFFFF if WINELIB32.
* [rc/rc (new file)]
Created the shell script 'rc', which should simplify resource
compilation.
* [win32/environment.c]
Kludged around an undefined reference to wine_files. This change
should be fixed some time.
* [win32/time.c] [if1632/kernel32.spec]
Added the functions GetSystemTime(), and Sleep().
* [miscemu/int21.c]
Renamed static function GetSystemTime to INT21_GetSystemTime to
avoid conflicts with the API function of the same name.
* [include/wintypes.h]
Added the SPFMT definition for printf statements.
* [misc/shell.c] [include/shell.h]
Changed ERROR_* defines to SHELL_ERROR_*, as they were conflicting
with the ones in include/winerror.h. They should probably use the
versions in winerror.h, but I'm not certain, and that can be done
later.
* [windows/mdi.c]
Translated WM_MDIACTIVATE(?,(LOhwnd,HIhwnd)) messages to
WM_MDIACTIVATE(HIhwnd,LOhwnd) for WINELIB32. The ? parameter
(boolean) was discarded with this translation. Translated handler
of WM_MDISETMENU(ref,(loHMENU,hiHMENU)) to handle
WM_MDISETMENU(loHMENU, hiHMENU) messages in WINELIB32 (ref assumed
false, call DrawMenuBar() if desired).
* [*/*]
General explicit casts and more rigid typing to remove warnings.
* [include/winpos.h] [windows/winpos.c]
Changed return type of WINPOS_ChangeActiveWindow to BOOL.
* [include/commdlg.h] [misc/commdlg.c]
Added prototypes for ChooseColor(), CommDlgExtendedError(),
FindText() GetFileTitle(), GetOpenFileName(), GetSaveFileName(),
PrintDlg, and ReplaceText().
Renamed the CommDlgExtendError() function to CommDlgExtendedError().
Made GetFileTitle return a short, as per the API definition.
* [Makefile.in]
Added line to clean and distclean that removes temporaries from
the include directory.
Sat Dec 16 19:39:14 MET 1995 Steffen Moeller <smoe0024@rz.uni-hildesheim.de>
* [controls/edit.c]
Almost rewrote EDIT_GetLineMsg.
Sat Dec 16 13:51:48 MST 1995 Andrew Taylor <andrew@riscan.com>
* [windows/mdi.c]
Fixed MDITile() bug that occurs when 0 windows are present or all
windows are minimized.
Wed Dec 12 23:30:00 1995 Uwe Bonnes <bon@elektron.ikp.physik.th-darmstadt.de>
* [misc/profile.c]
Try harder to find files, especially in the working directory.
Look in $HOME/.wine too and create it there if it isn't found.

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.
