Problems with WM_NCHITTEST and HTTRANSPARENT
by Ove Kaaven March 14, 2001

March 14, 2001

I'm currently having problems with this situation: Thread 1 owns some controls (modeless dialog box, actually) Thread 2 owns a window that covers the dialog (let's say it's like a "skin" or something...) The window procedure for thread 2's window return HTTRANSPARENT in its WM_NCHITTEST handler, so in theory mouse messages should get passed down to thread 1's controls. Now, what happens is this... -Mouse message arrives at thread 2 -TranslateMouseMsg calls WINPOS_WindowFromPoint -WINPOS_WindowFromPoint sends a WM_NCHITTEST to window -Window procedure returns HTTRANSPARENT -WINPOS_WindowFromPoint finds the controls, and returns that -TranslateMouseMsg wakes owner of controls (thread 1) -Mouse message arrives at thread 1 -TranslateMouseMsg calls WINPOS_WindowFromPoint -Since the transparent window is not owned by the current thread, WINPOS_WindowFromPoint doesn't bother to send it a message, but rather returns HTCLIENT directly -WINPOS_WindowFromPoint returns the transparent window -TranslateMouseMsg wakes thread 2 Repeat. This blocks all further mouse input processing, by the way... Any ideas on how to solve this, or whether it's supposed to work at all? I think I could fix some games if this worked... otherwise I'll have to think of some other way...

My reply was more targeted at the dumping of the window handles; I don't deny switching tracing on or off would be useful, but it needs to be done in a more generic way. Also this can be done externally to Wine, so that we don't need to burden the core dlls with extra command-line options or magic key sequences. There are many ways of doing that; an output filter is very easy to do and would work in many situations; if you need more complex stuff you could do it from the debugger, or write a small app that uses the debug API to manipulate the tracing state. -- Alexandre Julliard julliard(a)winehq.com

The above is IMHO a rather clintonesque use of the words emulator and executable. They hide the comparable code in NetBSD's dynamic linker instead. Not impressed, eventhough we could and probably should do that in the future. However if we hide the fact Wine is run, many user will not realize that it really is Wine's fault that their Win32 application crashes and say to their friends that Linux is unstable which gives Linux a bad reputation. We don't want that do we? So we probably shouldn't make it transparent at least not as long Wine still is alpha. > PEACE consists of the following 3 components: > > 1.In-kernel *.EXE loader Can't find the source but can't imagine it is very complicated.

This way you can have >much more flexibility I don't see why. 2 other points : 1) I wonder if I will not lose in speed with this approach; it seems to be more efficient to stop the output ASAP, than to filter data after it has passed through a pipe. I have timed Bcb4 loading with Wine on my computer (K6-350) - without any trace : 48 seconds With a simple -debugmsg +win,+relay : - with my patch : 70 seconds -> 22 seconds overhead - with a redirection to /dev/null : 95 seconds -> 47 seconds overhead I don't know if a pipe would be more efficient that a redirection, though. 2) I don't see how I will get the window list I generate with WIN_WalkWindows if there is no change at all in Wine - I should have said that to cut in the trace size in not a goal per se, but a mean to make debugging easier. If I have to make a first run with full trace that I have to browse to see what is the meaning of the window handles appearing in the trace, I lose a lot of time. Having immediately a view of all existing windows is *very* handy. >, and you don't need to hardcode a specific key >that some apps may need. But my patch does not use the Alt+F12 key if the -dt command line option is not used. It's true that some apps use this key, but in this case it's only debugging that is affected because the app does something when I use this key. It has never been a problem until now. Maybe a signal could be used instead. Gerard

I guess it > follows in the tradition of words like "nasty". It follows the same tradition as the word quisling which means "A traitor that serves as the puppet of the enemy occuping his or her country." after Vidkun Quisling the notorius Norwegian traitor. Being clintonesque means "Deliberately distorting the meaning of a word or words in order to make somebody believe something that is not true." Compare Bill Clinton saying "I did not have sex with that woman" using a rather non standard definition of the word sex. In the case PEACE this might not have been deliberate, but because of ignorance, so perhaps the use of the word clintonesque was too harsh. > > Not impressed, eventhough we could and probably > > should do that in the future. > > > > I thought there was another kernel module running around that > loaded wine > for exe files.

The advantage of a kernel module loader is that you can do relocation on demand as well as having the ability to just discard such pages when memory is low instead of swapping them out. > Codeweavers is on the right track here, allowing users to > launch Windows > apps from gnome by creating a file association.

Indeed and if they prefer not to communicate in english, setting up a wine-devel-jp mailing list shouldn't be a problem.

They use the BSD license, unfortunately the one with the advertisment clause. However I don't imagine it will be a problem since there is very little if anything that they have implemented that we haven't implemented I long time ago already. Additional problem is that they use C++. :-) In short they have wasted a lot of effort for little or no gain. > Other than that I'm tired of YAW (Yet Another Windows, which is > the name of yet another windows package, coincidentally ;-) Indeed. I can understand people that start working with a project has a lot of ideas and the project leader rejects them and they grow tired and decide to do it themselves. However for a project like Wine most things really can't be done that many ways since it must be compatible with Windows so this shouldn't really be a very large problem. In this case perhaps they, being Japanse, felt uncomfortable with cooperating with english speaking people. I noticed that they have a Japanese only mailing list. Anyway we could always create a wine-devel-jp or whatever if that was a problem.
