ChangeDisplaySettings
by Travis Michielsen 17 Jul '01

17 Jul '01

Hi, I was planning on implementing ChangeDisplaySettingsA soon but I'm not certain on how to do it. I have been browsing the source tree and was following the methods used by DirectDraw and was considering a similar approach. While I was browsing the source, I was eventually lead to dlls/x11drv/xvidmode.c which contains most of the functions that I will probably need. But I still have a few concerns: 1) Is the x11drv used for ddraw AND the gdi or just one? 2) what is the best way to query if the video exists? without knowing syncs? 3) and if i need to know syncs how do I find them? Another question I have is about pixel depth. From what I understand, it is imposible to change the pixel format of the screen while X is running. However, it is possible to start more than one X server with different configs (and depth) which we could use if we have to but probably not a good idea. Of course another posibility is to emulate the pixel depth, but that would probably cause performance problems, especially when used by games. Anyone have any suggestions or should we just leave changing depths as unimplemented? Thanks! - Travis Michielsen __________________________________________________ Do You Yahoo!?

DrawText
by Travis Michielsen 17 Jul '01

17 Jul '01

Hi all, I have put together a quick patch that SHOULD fully implement the DrawText functions. However, I have not had time to thoroughly tested most of the logic so I thought I would post it here rather than sending it directly to the patches list. I welcome any/all comments/suggestions. - Travis Michielsen Index: wine/dlls/user/text.c =================================================================== RCS file: /home/wine/wine/dlls/user/text.c,v retrieving revision 1.12 diff -u -r1.12 text.c --- wine/dlls/user/text.c 2001/07/17 00:51:00 1.12 +++ wine/dlls/user/text.c 2001/07/17 13:55:22 @@ -235,6 +235,7 @@ int prefix_x = 0; int prefix_end = 0; TEXTMETRICW tm; + int lmargin = 0, rmargin = 0; int x = rect->left, y = rect->top; int width = rect->right - rect->left; int max_width = 0; @@ -242,10 +243,8 @@ TRACE("%s, %d , [(%d,%d),(%d,%d)]\n", debugstr_wn (str, count), count, rect->left, rect->top, rect->right, rect->bottom); - if(dtp) { - FIXME("Ignores params:%d,%d,%d,%d\n", dtp->cbSize, - dtp->iTabLength, dtp->iLeftMargin, dtp->iRightMargin); - } + if (dtp) TRACE("Params: iTabLength=%d, iLeftMargin=%d, iRightMargin=%d\n", + dtp->iTabLength, dtp->iLeftMargin, dtp->iRightMargin); if (!str) return 0; if (count == -1) count = strlenW(str); @@ -258,8 +257,17 @@ else lh = tm.tmHeight; + if (dtp) + { + lmargin = dtp->iLeftMargin * tm.tmAveCharWidth; + rmargin = dtp->iRightMargin * tm.tmAveCharWidth; + if (!(flags & (DT_CENTER | DT_RIGHT))) + x += lmargin; + dtp->uiLengthDrawn = 0; //This param RECEIVES number of chars processed + } + if (flags & DT_TABSTOP) - tabstop = flags >> 8; + tabstop = dtp ? dtp->iTabLength : flags >> 8; if (flags & DT_EXPANDTABS) { @@ -292,7 +300,7 @@ if (flags & DT_SINGLELINE) { - if (flags & DT_VCENTER) y = rect->top + + if (flags & DT_VCENTER) y = rect->top + (rect->bottom - rect->top) / 2 - size.cy / 2; else if (flags & DT_BOTTOM) y = rect->bottom - size.cy; @@ -312,7 +320,7 @@ if (flags & DT_WORD_ELLIPSIS) flags |= DT_WORDBREAK; - if (flags & DT_PATH_ELLIPSIS) + if (flags & DT_PATH_ELLIPSIS) { WCHAR* lastBkSlash = NULL; WCHAR* lastFwdSlash = NULL; @@ -320,14 +328,11 @@ line[totalLen] = '\0'; lastBkSlash = strrchrW(line, BACK_SLASHW[0]); lastFwdSlash = strrchrW(line, FORWARD_SLASHW[0]); - fnameDelim = lastFwdSlash ? lastFwdSlash : lastBkSlash; - if (lastBkSlash && lastFwdSlash) /* which is last? */ - if (lastBkSlash > lastFwdSlash) - fnameDelim = lastBkSlash; + fnameDelim = lastBkSlash > lastFwdSlash ? lastBkSlash : lastFwdSlash; if (fnameDelim) fnameLen = &line[totalLen] - fnameDelim; - else + else fnameDelim = (WCHAR*)str; strcpyW(swapStr, ELLIPSISW); @@ -343,16 +348,16 @@ } len = MAX_STATIC_BUFFER; - TEXT_NextLineW(hdc, swapStr, &count, line, &len, width, flags); + TEXT_NextLineW(hdc, swapStr, &count, line, &len, width, flags); /* if only the ELLIPSIS will fit, just let it be clipped */ len = max(3, len); GetTextExtentPointW(hdc, line, len, &size); /* FIXME: - * NextLine uses GetTextExtentPoint for each character, + * NextLine uses GetTextExtentPoint for each character, * rather than GetCharABCWidth...

fnt2bdf.c and font names
by Bill Medland 16 Jul '01

16 Jul '01

I've just been playing with fonts (sserife and vgasys) to get things working. In the process I notice that fnt2bdf seems to do some strange stuff about choosing a font name, pixel size etc. I don't want to submit a patch that merely demonstrates my stupidity/lack of understanding but am willing to put in my suggested fix. This will result in for example the MS Sans Serif 8 pt font getting a name of -windows-MS Sans Serif-medium-r-normal-sans-13-80-96-96-p-50-microsoft-cp1252 SIZE 8 96 96 as opposed to the current -windows-MS Sans Serif-medium-r-normal-sans-13-130-72-72-p-50-microsoft-cp1252 SIZE 13 96 96 (I don't understand why the 72 dpi is hard-coded) Do I submit it or am I misunderstanding something Bill

Mouse trouble
by Daniel Bingham 16 Jul '01

16 Jul '01

Hi, I just got the latest CVS and when I tried to run starcraft my mouse won't move. I have dxgrab turned on so as not to have my mouse going off the screen when I try to move. I am not very knowledgeable about wine or programming, so I thought I'd tell someone who was. If I have something set up wrong I can't find it and don't find any documentation to address it either. Any help would be much appreciated. Please email me directly because I get the digest and tend to ignore it. Thanks. Daniel Bingham db78(a)att.net

Hi, >Native msvcrt has __CxxFrameHandler, but I aggree that wine-msvcrt needs >exception facilities too. While I'm still on holiday, i just bought a laptop to do some wine coding on. I had improved the exception handling in builtin msvcrt but my last run of patches to it werent accepted due to using asm instead of register funcs. Once I get my old sources mailed to me I will begin hacking on it again. I'm interested in getting the konqueror/ActiveX stuff working with builtin msvcrt, since the dot.kde.org press release singled it out as non-functional (much to my shame <g>). Meanwhile I'm strolling through shlwapi and should have some patches for that soon. Its great to see the progress made since february though, very impressive.

Significant change to WINEPS - please test!
by Ian Pilcher 16 Jul '01

16 Jul '01

The attached patch makes a fundamental change to the way the PostScript driver deals with character encodings -- it ignores them. Instead, the driver now operates directly on 16-bit Unicode characters. This should be a more robust strategy for handling non-Latin, and especially multi-byte, character sets. I really have no idea, however, how the rest of Wine handles non-Latin characters. As an English speaker, I'm not well equipped to test it. So please give me your feedback. I particularly want to know if it breaks anything before I submit it.
