DC ownerdrawn background mode
by Fabian Cenedese Dec. 18, 2003

Dec. 18, 2003

Hi I have a control derived from CListCtrl. It's completely ownerdrawn. The problem comes when some item is selected. The whole column is drawn selected but the text is drawn with the actual back color instead of transparent. As this is white I get white text on white background... very readable :) I found that the difference between Windows and wine is the background mode. In Windows it's transparent whereas in wine it's opaque. I never change the background mode in my app, I guess I just lived from the fact that it's default transparent. Where is this set? Is this a wrong default parameter in wine or do I explicitly have to set the background mode in my app? I can do this, then it shows ok. But that's another change to my application I have to do because of wine. Maybe other apps may have similar problems. bye Fabi // from my code: void CMyCtrl::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct) { // Prepare and test device context CDC* pDC = CDC::FromHandle(lpDrawItemStruct->hDC); // this is 1 for windows but 2 for wine // pDC->GetBkMode(); // wine fix pDC->SetBkMode(TRANSPARENT);

Fix for debugger breakage
by Mike Hearn Dec. 18, 2003

Dec. 18, 2003

Hi, What is the status of this problem? I tried setting WINELOADER to point to wine-pthread, and while that allowed winedbg to load symbols it spewed loads of errors while doing so. Is there a proper fix for this? BTW I think the recent URL Cache patch broke the IE setup program, I get a crash there calling InterlockedExchange with a null pointer dereference. thanks -mike

winedbg question
by Chris Morgan Dec. 18, 2003

Dec. 18, 2003

Should winedbg be able to load symbols up for non-wine libraries? After the export WINELOADER idea I've got wine symbols but I'm still trying to debug a bizzare crash in winejack where I get: ~/c$ wine sndrec32.exe Could not stat /mnt/fd0 (No such file or directory), ignoring drive A: Segmentation fault and when running under winedbg: *** Invalid address 0x40017f40 (_end+0x2ff03f40) Loaded debug information from ELF '/usr/local/lib/wine/ midimap.drv.so' (0x41090000) In 32-bit mode. Wine-dbg>cont Stopped on breakpoint 1 at 0x0100d32e (sndrec32.exe.EntryPoint in sndrec32.exe) Wine-dbg>cont Invalid address for breakpoint 1, disabling it Invalid address for breakpoint 2, disabling it Process of pid=0000000a has terminated Wine-dbg> >From single stepping I've found the function where the segfault appears to occur but its inside of jack_activate() in libjack.so.0 but symbols for this library don't appear to be loaded: *** Invalid address 0x40017f40 (_end+0x2ff03f40) No debug information in ELF '/usr/local/lib/libjack.so.0' (0x40f56000) No debug information in ELF '/lib/tls/librt.so.1' (0x40f62000) nm libjack.so.0 lists a bunch of symbols and I'm able to set a breakpoint on jack_activate() using gdb on a native linux app so it looks like debug information is built into libjack.so.0.

Problem with "exec shield" workaround
by Troy Rollo Dec. 18, 2003

Dec. 18, 2003

The "exec shield" workaround (loader/main.c, libs/wine/port.c) has a side-effect of leaving a several thousand byte area of memory allocated just after the reserved pe_area. Under Windows, it is possible to fairly reliably map files or allocate memory explicitly using a fixed address of 0x10000000. The left-over memory from the loader causes programs that rely on this to fail. It seems that this workaround should either be a user setting or should mmap the memory area desired so that it can be removed without leaving behind a small fragment after that area.

default config file creation
by Chris Morgan Dec. 17, 2003

Dec. 17, 2003

I was chatting with Rudolf Kastl(che on #winehq) and he was mentioning the things that he was doing for the rpm package. One of the patches he applies to wine prior to packaging it is a patch that creates local user config files if they don't exist. This helps end users as they don't have to worry about the package maintainer providing valid config files. I thought this sounded like a pretty neat idea to improve usability. The patch currently copies files from /etc/* which means they would need to be installed there during the process. I was wondering if it would make more sense during the compile process to take the default configuration files, config, system.reg, user.reg and userdef.reg and convert these to binary form and compile them into the wine binary itself. We could detect the lack of these files at startup and install them for the user. Another feature could be a command line switch that would rebuild a users config, like: 'wine --rebuild-config' that would reset the users config back to the defaults. Sound like something reasonable? Should we instead be putting the default files somewhere on the users machine and copying them over like the patch does? Chris

All this can be solved by shipping a config file with with wine, get wine to adapt it to the users system, install it, install the registry and create the fake windows partition. This would work for all binaries on all distros, even on freebsd, and would work when installing from source. Only that someone has to implement it. And volunteers?

You can install the files anywhere, as long as the location isn't already used for something else, /etc/wine could do. Also, compiling the files means nobody could change the default config without recompiling wine, that sound short of weird. Ivan.

I also had a look at the recording of your speech about wine packaging at wineconf 2002. I've followed the indications of documentation/PACKAGING at lines 385-404, mainly for usability. > Feel free to copy the attached SuSE default make_fakewindows setup script I > use and the included minimalistic wine patch to loader/main.c. It all seems quite SuSE specific, anyway I haven't yet seen a script that works as well as winesetuptk, and there are complaints from time to time about helper scripts shiped with RPMs. Also a script doesn't give a user the freedom of choosing if he wants to use a real or a fake windows partition, and doesn't allow the user to chose where to have the fake windows partition, simply because it can't interact with the user. Nobody seems to be currently shipping winelauncher,and having a scipt to start wine isn't a great idea for a beta/stable build and ideally we want a long term solution.

The default config file in /etc can then be >modified so that it matches the distribution (redhat have their cd at >/mnt/cdrom) and it can be modified by the sysadmin There is no need to add text files to the wine binary, but the default config should be modified on the fly. Some computers don't have a cd or a floppy, some have 2 cd drives, some don't use distro-standard paths, so drives should be detected on the fly, already we have enough logs from users full of /mnt/floppy not found and /mnt/cdrom not found, and it's not a great feature for 0.9 or 1.0. Winesetuptk does thit very very very well, I'm no engineer but I suppose that something written in tcltk can be easily ported to C. A binary package (But also a normal make install) should install configb and registry in /etc/wine or /usr/share/doc/wine-version/samples or something like that. The user should then start wine, that would look for $HOME/.wine, create it if necesarry, figure out the removable media paths, create a config file on the fly, write it to $HOME/.wine, run 'wine regedit path/to/winedefault.reg' and start normally.This does not require a script, will create a properly working config file, and the default configuration can be tweaked/restored with winecfg, once it's finished.

Mouse usage when Wine not in focus
by Mark Knecht Dec. 17, 2003

Dec. 17, 2003

Hi, Please excuse me for bringing this question here. I'm not a developer. I have asked this in a couple of different forums but to date have received no answers. I will copy a message sent earlier this week to Wine-Users and hope for some insights on how to handle it. I have done some Googling around and run across numerous emails about mouse focus, but there doesn't seem to be anything in the Wine-HQ FAQ or Online Docs that tells me how to handle this. The basic issue in a nutshell - How do I configure Wine to not pay attention to the mouse when the Wine window is not in focus? Just in case it matters, I'm using fluxbox on all my systems, but I checked xfce4 and had the same problem. Thanks, Mark <SNIP> Hi, Is there a way to have mouse movements & positions not be sent to a Wine app when the Wine desktop is not the active window? I have looked through the online docs and the FAQ but I see nothing about this problem I'm having. I hope it's just a configuration issue, but I cannot find much info in the docs about mouse configuration at all. Also, I have seen this issue under Crossover Office and WineX, but have not had a chance to check Wine CVS yet, so if it's fixed or a non-issue just let me know. Thanks in advance. Under Windows I have played a game called Caesar 3 for years. Finally with some help from another wine user, I got it working perfectly (as far as I can tell) on Saturday using an ebuild of WineX on a Gentoo 2.4.20 kernel. The game plays well. I do have one problem when the game resolution and the Wine desktop are not the same size, but we can save that for another email if it's of interest to anyone. Anyway, the way the game works is that it has a play area for building your city. To move around this play area you drag your mouse to the edge of the board and the area scrolls inside the window. When playing the game under Wine, using the first config files I had with WineX and cxoffice that had "DXGrab" = "Y", the mouse stayed inside the Wine desktop and the game always worked fine, but I couldn't use the system for anything else unless I tricked Wine into letting my mouse escape from the desktop trap by using another window in the background. I then found the "DXGrab" option and changed it to "N" and I was able to get my mouse out of my Wine desktop and get email, etc. However, even when the Wine desktop and game are not in focus the mouse position is being fed to the game, so the game scrolls around underneath while I use items and applications on my desktop. How can I configure Wine to not send any mouse position information to the game when the game is not in focus? Right now I cannot take a meaningful screenshot since the game area is drifting around all the time. Thanks in advance, Mark <SNIP>
