I just ripped out the interesting parts from Speak freely in order to find a simple program exhibiting the problems. What I ended up with was a program which does nothing interesting except to show a simple dialg using CreateDialog(). It still doesn't work under Wine. The source is attached. I'm somewhat at a loss about what to do now. I'm just not clear about what should happen and why it doesn't. Some browsing around in the source suggests that it may related to the focus problems Gerard has been talking about, but I'm far from sure. Any comments?

Hi all. I've seen in the recent past a task list for newbie developer for wine. I would like to know what are still open, how I could contribute. I've very few skills in Windows development. However, I've good knowledge of development under linux, and usage of gnu tools (autoconf). Bye Marco -- Marco Bizzarri - Responsabile Tecnico - Icube S.r.l.

I think that the problem with focus is that when a window is shown by Wine, synthetic WM_GETFOCUS and WM_SETFOCUS events are generated, that are themselves generating X focus events. The X events are kept in the X queue until Wine finds time to handle them. Wine creates window A : WM_GETFOCUS for A Wine creates window B : WM_KILLFOCUS for A, WM_GETFOCUS for B Wine creates window C : WM_KILLFOCUS for B, WM_GETFOCUS for C Now, when after all this the X events are processed, Wine handles a X focusin event for A, that is generating a WM_GETFOCUS, then a focusout for A, generating other WM_KILLFOCUS and WM_ GETFOCUS, focusin for B, etc..; the sequence of events when creating windows is perfect, but there are extra events after. IMO what's wrong is that X focus events are not ignored when they are the following of program action. The following hack disables focus handling in this case. I have no clue on its value since I am currently struggling with other bugs. and I will not come to these problems until some time - maybe a lot of time if current Wine progress (aka regressions :-)) continues. --- event.c.orig Fri Aug 24 09:30:46 2001 +++ event.c Mon Sep 10 13:00:28 2001 @@ -534,6 +534,8 @@ if (!hWnd) return; + if (!event->send_event) return; + bIsDisabled = GetWindowLongA( hWnd, GWL_STYLE ) & WS_DISABLED; /* If the window has been disabled and we are in managed mode, HTH Gerard

Maybe the problem is that it succeeds. However, Win32s is present in Wine since years and has not been touched since a long time. I think unlikely that it could be a new problem - when was the last working Wine version before current Cvs ? You can find in documentation/cvs-regression a few tips on how to search for the exact date of a regression. FYI the Wine app database list this game as 'playing perfectly directly off the CD' :-) Gerard

There is no hwnd type in the spec files, AFAICT. That's not a matter of typing GetWindow(hwnd word) instead of GetWindow(word word) - I think it is necessary to actually change winebuild to define a new type and write a bunch of code to support it. I have looked at the points where it current cvs crashes and it's necessary to fix 16 to 32 bits handles and I have found that 2 changes cure all my new crashes : the one in DestroyWindow16 and another in DefWindowProc16 The reason for these problems is the same : Wine is keeping window handles in several variables (active window, focus window) and Wine code does several comparisons between applications provided handles and these values. In the last case for example, the test /* activate hwndTop if needed. */ if (hwndTop != GetActiveWindow()) { in focus.c fails because of the high word part (and creates an infinite focus loop) I'd say that by adding also handle fixes in SetWindowPos16, SetFocus16 and SetActiveWindow16 as well as fixing the handles setters in queue.c, everything would be covered. IMO your solution is 1) somewhat complex for a fix to apps not widely used anymore 2) overkill because it's not necessary to convert window handles for each and every Api. OTOH your solution is more elegant. I don't know what to do. Gerard

Dialog painting
by Niclas Karlsson MATE Sept. 10, 2001

Sept. 10, 2001

Hello! Wine currently seems to have a problem painting splash dialogs properly (or at all). Is this a known problem (with a known cause)? An open source program exhibiting problems of this kind would be Speak Freely (http://www.fourmilab.ch/speakfree/windows/) I will try to single out the cause of the problem when I get a little spare time, unless the cause is already known that is. Also, I haven't used Wine for some time so I don't know if this is a long-standing problem. The version I used was a cvs snapshot from last friday before the commits.

what if MS is forced to publish all API's?
by Scott Bradford Sept. 9, 2001

Sept. 9, 2001

with all the discussion going on in the press about what to do with Microsoft to remove their Monopoly power or at least see to it that they don't abuse their power, how to folks here feel about forcing them to release all their API's? I'm not a programmer myself, but it's my understanding that not having access to the API's is what makes wine such a challenge. If this is the case, would getting access to the MS API's allow Wine to be completed? I feel that a MS breakup wouldn't have done much to change things because they can still give information only to whom they choose, leaving MS to decide who can play and who can't. Having other ways to run the application base of windows software would remove the need to run windows itself, and in my mind, this is the easiest way to remove monopoly power of MS. What do you folks, the Wine developers, think should be done to MS?

Focus livelock
by Jukka Heinonen Sept. 9, 2001

Sept. 9, 2001

I posted a patch that would fix a focus related livelock. However, I have to admit that the patch is quite hacky and likely not to be included in Wine. Since I would like to get this bug fixed, I thought to ask opinions about the correct way to fix the bug. The short description of the bug is that setting active/foreground/focus window in Wine calls X11DRV_SetFocus, which calls XSetInputFocus. This makes Wine receive FocusIn event, the handler of which calls SetForegroundWindow. Even though SetForegroundWindow does nothing if its parameter matches current foreground window, it can be easily seen that having more than one window can lead into livelock. This happens repeatably every time you start Colonization for Windows. I'm currently thinking about calling directly some WINPOS_* routine from X11 FocusIn handler instead of SetForegroundWindow. If the routine acted exactly like SetForegroundWindow except it made sure that it causes no calls to X11DRV_SetFocus, focus problem would be fixed. Unfortunately I have not figured any good way to pass an extra flag to default handler for WM_ACTIVATE, so that the routine would call something like SetFocus_DontCallDriver instead of regular SetFocus... -- Jukka Heinonen <http://www.iki.fi/jhei/>

This caused a division by zero in convert_modeline.

I don't think such a server exists. There's either XFree86 4.x with loadable driver modules, or there's XFree86-SVGA 3.x. The latter sounds more likely to have this kind of bug.
