Help with nonclient Windows 95 frame
by Bill Medland 06 Jul '01

06 Jul '01

I'd appreciate some advice here before I mess things up for everyone else. In the longer term I am fixing a border issue with the edit control, but before doing so I am fixing up the nonclient frame drawing code (i.e. NC_DoNCPaint95). The code contains quite a bit of calculation based upon the system metrics. The code seems to reflect the Windows documentation. However it should come as no surprise that there are disagreements between that documentation and what I see on my Win95 computer! For example a frame with WS_THICKEDGE but no WS_BORDER nor WS_DLGFRAME nor WS_EX_DLGMODALFRAME on my computer is only 3 pixels wide, not 4 (although one of those pixels is the COLOR_WINDOW associated with the WS_THICKEDGE) Is there a way to adjust the size of the borders on the Win95 to be able to see what affects what?

Mouse events
by Duane Clark 03 Jul '01

03 Jul '01

Howdy, Just tried the most recent CVS. I found that the patch from 6/25 to windows/x11drv/event.c has led to mildly annoying mouse behavior in certain (admittedly very limited) cases. Here is the change that did it: @@ -292,21 +291,8 @@ case ButtonRelease: EVENT_ButtonRelease( hWnd, (XButtonEvent*)event ); break; case MotionNotify: - /* Wine between two fast machines across the overloaded campus - ethernet gets very boged down in MotionEvents. The following - simply finds the last motion event in the queue and drops - the rest. On a good link events are servered before they build - up so this doesn't take place. On a slow link this may cause - problems if the event order is important. I'm not yet seen - of any problems. Jon 7/6/96. - */ - if ((current_input_type == X11DRV_INPUT_ABSOLUTE) && - (in_transition == FALSE)) - /* Only cumulate events if in absolute mode */ - while (TSXCheckTypedWindowEvent(display,((XAnyEvent *)event)->;window, - MotionNotify, event)); EVENT_MotionNotify( hWnd, (XMotionEvent*)event ); break; I assume some problem led to its removal. I regularly try out Myst (the 32 bit version) as a test, running locally on a 700MHz Athlon, so this can't be blamed on a slow ethernet connection or slow machine. When dragging the slide controls in the "planetarium", they used to follow the mouse just fine. With this patch, if you grab the control, move the mouse and release it, the control does not keep up with the mouse but just moves at a moderately slow pace until it reaches the point where the mouse was released (a few seconds to travel from one end to the other). At that point everything returns to normal. Other similar slide controls, such as the musical slide controls in the space ship, work fine with the patch, however. Perhaps it is possible that the code above was masking some other problem causing the control to move too slowly to follow the mouse? Duane

Win16 problems
by Ove Kaaven 03 Jul '01

03 Jul '01

Is it just me, or does no Win16 GUI apps work in the current Wine CVS? If Wine is compiled with --enable-opengl, then we get BadMatch errors in X_CreateWindow (some kind of visual mismatch), If I disable the OpenGL visual, then the windows are created and seem to exist, but they're never drawn. Win32 apps work fine, of course. I could probably look into the OpenGL problem if that was the only problem, but why are Win16 windows never drawn anyway? (Unfortunately, I don't have sol.exe here, I tested with MS Word Viewer 16-bit, but DOS apps like Monkey Island gets the same issues in my tree)

Mixed mode CD's and volume label
by David Hagood 03 Jul '01

03 Jul '01

I was trying to get Half-Life running under Wine last night, and ran into a problem with getting the CD label under Wine. Since the HL CD is a mixed mode data/audio disk (as are most game disks nowadays) Wine complained with a We don't have a way of determining the label of a mixed mode CD - Linux doesn't allow raw access ! However, Xcdroast was easily able to access the data. As an experiment, I disabled this check in misc/cdrom.c, and it worked quite happily. Perhaps this check is out of date. Perhaps it is my system setup: 2.4.6-pre7, Samsung CD-Writer/DVD reader on IDE, ide-scsi module loaded, Wine configured to use the /dev/scd0 link. Now, if I could just work out why the OpenGL is flashing...

Window painting problem
by Glenn Schrader 03 Jul '01

03 Jul '01

I've been tracking down a window painting problem and I think that I know whats happening but I'd like to get some opinions on the 'right' way to fix it. The symptom is that (in some cases) any change to a window will cause the entire window to be repainted. For instance, using the mouse to select a single character causes the whole window to update rather than just the small region which needs to be highlighted. This doesn't happen on most applications. In fact, the only one where i've seen this effect is RoAClient (a really good MUD client). Even so, its really annoying and makes the window flash so much that the app is effectively useless. The problem appears to be in BeginPaint. There is a test which checks to see if the window has the CS_PARENTDC flag set. If so then then the update region is discarded and the window is painted. This has the side effect of making the whole window repaint every time anything in the window changes. According to the windows docs that i've looked at, the CS_PARENTDC should just make the window paint using its parent's device context. There isn't any mention of also removing the invalid region clipping so i'm pretty sure that what BeginPaint is doing isn't right. In my hacking around, I disabled the branch of the test which removes the clipping region and things appear to work a lot better. The screen updating is definitely smoother. What I'm not sure of is whether this is good enough or whether the CS_PARENTDC case really should be slightly different. Normally the clipping region is offset relative to the window thats being drawn but with CS_PARENTDC should the offset be done relative to the parent window instead? Are there any other subtle things that CS_PARENTDC affects? Any insight would be appreciated... Thanks much, G. Schrader

For me Win16 apps have not more problems than Win32 ones. Word viewer 16 bits has one regression with current Cvs vs say one month ago, a focus problem that is occuring only in managed mode. Other than that, it is starting and loading files, either on my old computer with Xfree 3.3 and on my newer one with Xfree 4 (compiled with --enable-opengl) I still run most of my test apps on the old computer, but none of them crashes and the new redrawing problems are less than what you say. IMO Wine behaviour depends more now on the specific X server and window manager. I use Kde on both computers, btw (1.1.1 and 2.1 respectively) Gerard

Re: PATCH: setsockopt differences for winsock/winsock2

I'd suggest writing a ws1-to-ws2 conversion function instead, and use it (by duplicating its code) both for the 16-bit functions in ws2_32 and for the version 1 functions in wsock32. A little code duplication is better than adding entry points. An even better alternative that would avoid the duplication could be to have the 16-bit functions implemented in wsock32 instead of ws2_32, but this is probably a lot more work. -- Alexandre Julliard julliard(a)winehq.com

tray icon creation problem
by Adriaan Moors 03 Jul '01

03 Jul '01

hi, earlier, i reported a problem with create_icon_window. It doesn't crash anymore with today's cvs (it says an error occurred when initing the tray icon). The application (winmx) continues to load, but it keeps moving downwards. This only occurs when using enlightenment, with window maker it stays still :-) Maybe it's a bug in enlightenment? regards adriaan moors -- Have you ever noticed that the people who are always trying to tell you, "There's a time for work and a time for play," never find the time for play?
