RFC: Should we use the macros in windowsx.h to fix -DSTRICT warni ngs?
by Patrik Stridvall 10 Aug '01

10 Aug '01

This is not primarily a patch it is a RFC. I have experimented a bit with fixing the strict warnings. I have a few patch that I haven't submitted yet partly because I'm not 100% sure how all warnings should be fixed. Anyway, one large class of warnings is the ones cause by the window messaging functions. Like the one below: SendMessageW(lphc->hWndEdit, WM_SETTEXT, 0, (LPARAM)empty_stringW); This one unlike others this one does cause any warning with -DSTRICT because of the ugly cast, but the principle is the same. The only good way to fix this kind of problems that I can see is to use the FORWARD_WM_* macros in include/windowsx.h to write it like: FORWARD_WM_SETTEXT(lphc->hWndEdit, empty_stringW, SendMessageW); This works fine because the FORWARD_WM_SETTEXT macro look like this: #define FORWARD_WM_SETTEXT(hwnd, lpszText, fn) \ (void)(fn)((hwnd), WM_SETTEXT, 0L, (LPARAM)(LPCTSTR)(lpszText)) Actually I lied this special case will not work fine since FORWARD_WM_SETTEXT uses TCHAR and friends. But that is not so important for the general principle. See below. Anyway, in some meaning the macros only hides the casts, but can casts really be avoided? We must cast to {W,L}PARAM at some time mustn't we? And the macros in windowsx.h is not that bad they cast to the correct type before the cast to {W,L}PARAM. This might help to find some bugs. Perhaps rewriting to macros as inline functions might help to? So the question is: Should we use the FORWARD_WM_* macros to avoid typecasts (or rather avoid visable typecast) or should we not? If not how should we fix the problems? And if we decide to use them, is patches like the one below to include/windowsx.h that fixes the TCHAR and friend problem acceptable or should we solve such problems in another way? PS.

trouble with fonts (old, old problem)
by Mike McCormack 10 Aug '01

10 Aug '01

Hi All, i've got a problem with fonts in Netscape that's been around for a long time, while i've tried several times, unsuccessfully, to fix. When netscape 4.77 first loads, then loads an arbitary page, everything (text, buttons, comboboxes) is rendered incorrectly. If i go to another page, then hit the Back button, the page that was originally rendered incorrectly is now correct. All further renderings are correct for all pages. In my investigations (some time ago), i found that : * font enumeration functions returned different things on the first and second load of the same page. * i could correct the problem by changing the default ansi fixed font to helvetica i suspect that the wine loads extra X11 fonts between the first and second page viewings... but i don't know much about font handling in wine. i'll make some screen shots if anybody is interested. Any ideas?

Font scaling in PSDRV_EnumDeviceFonts
by Ian Pilcher 10 Aug '01

10 Aug '01

Can anyone point me to the Win32 API that ultimately calls the subject function? I'm trying to understand why it scales fonts to a 200 logical unit (I think) character cell. Is this completely arbitrary?

Alexandre has made some changes in this area recently, but I don't believe they've changed that fundamental fact. So to do what you're proposing, you would first have to modify Wine's GDI code to support one of Microsoft's 32-bit graphics driver interfaces. (Different Microsoft 32-bit OSes have different driver interfaces, BTW.) You could then update x11drv to use this interface. As Patrik pointed out, this is really outside the scope of the Wine project, but I do think that it would be valuable. In addition to the reasons you give above, it would be helpful in improving both the Wine driver code and the Wine GDI code. -- ======================================================================== Ian Pilcher ian.pilcher(a)home.com ========================================================================

However to me it just seems like a silly hack to use the X11DRV_ functions for that or at least to use them directly. Anyway, so what you really want to be able to compile Windows source code to a Windows binary that instead of using normal USER/GDI instead uses Wine's version of USER/GDI that using the X11DRV displays the application's Window(s) on a X-Terminal? Hmm. Intresting idea. Well, yes that would be possible to do with Wine, at least in theory. There is a lot a practical problems to be resolved for that to work. Just getting the non-core parts (especially USER/GDI and X11DRV) to compile and link to a DLL with the Windows headers will be an effort by itself. Actually getting it to work will be even worse, The USER (and to a lesser part even GDI) seems, eventhough I guess they can be made not to, to use the Wine server for some things, with means that you will either have to fix that or emulate the Wine server on Windows. It is propably not that hard to emulate it, but quite a lot of work regardless. Then you have the issue of getting the Windows versions of COMCTL32 and COMDLG32 DLL:s and similar DLL:s using your special versions of USER32 and GDI32 and not the Windows ones. I'm not sure Windows can be made to support this at all. It depends on exactly how library loading work. Hmm, perhaps it would be possible to "hook" LoadLibrary somehow. Anyway, I'm sorry to say that it will currently not, with the state Wine is now, be possible to do that without an enormous effort. Despite this I'm happy to say that I think it will be possible some day. However not until past Wine 1.0 or perhaps not even past Wine 1.x. Nice idea though.

I think what I think you are proposing is currently entirely out of the scope of the Wine project. Wine is currently not designed for this. Compiling some of the non-core DLL:s like COMCTL32, COMDLG32 and others might be meaningful for test purposes, but the core stuff like the is simply not possible and it is not needed since Windows already has its own implementation of them that can used in the testing the non-core DLL:s. In short, what you are proposing is intresting but it has currently little to do with the Wine project. What you want to do is the write a Windows "graphic card" driver that display the result on an X-Terminal. While you certainly can (and are indeed legally allowed to do) use part of the x11drv to do this, I think most of the X11DRV is to high level to be useful. Sure someday when your "graphic card" driver works good we might consider redesigning Wine to use the Windows "graphic card" driver interface, but it will certainly not not be done before Wine 1.0 or even Wine 1.x. Perhaps Wine 2.0 might be a good point to merge such things with Wine, assuming of course that you or somebody else implements such a thing and releases it under an acceptable license (preferably the Wine license, the new one that is).
