I'm sorry if I came off cynical. There was no cynicism in that comment. I opened 2584 as a result of seeing your patch. I was not aware of this particular missing functionality.
I'm aiming for http://bugs.winehq.org/show_bug.cgi?id=609 to be the ultimate documentation of all BiDi APIs in Windows. Opening 2584 is a good thing, as it documents things that are still to be done.
What is wrong ?
It seems that this flag reverses the meaning of several common conventions (left/right etc.). The idea is probably so that applications that are natively right to left not have to change their design too much.
I can't tell you exactly what it means, however, as I don't know myself. It will probably be a matter of comparing behaviors to the real Windows. I have some doubts about whether anyone is even using this flag at all. Maybe on localized Hebrew Windows, where the whole window decorations are reversed (Ughh. My GF has localized XP Home installed. This thing is horrible, but I didn't spot any non-Windows native applications that were affected by it).
Tell me and I will help you, if you want...
I'll gladly accept all the help I can get. Basically, this particular unimplemented bit requires writing small test programs on Windows, and then running them on Wine until they produce the same results. The idea is that you read the MSDN page for the function (linked from the bug). That page also links to http://msdn.microsoft.com/library/en-us/winui/winui/windowsuserinterface/windowing/windows/windowfeatures.asp?frame=true#layout_mirroring, which gives more details on what this flag is supposed to mean. If you check out 2584 again, you will see I added this new information there.
The steps one takes is to read all the relevant manuals, and try to understand what this means. Next, you write a small test program that does stuff with and without this flag, showing where this flag takes effect on Windows. Next, you move this test program to Wine and start tweaking Wine until it behaves the same there.
There is also a last step, which is to make this program into a test suite, returning success or failure. I'm not sure, however, how that is supposed to be done for programs where success and failure are measured with graphical output.
Hope this helps you help me help everyone..... :-)
