Re: Toolbar background error

We are seeing it for toolbars because it's a trick that is used mainly for toolbars. What happens I think is that some apps are not satisfied with the standard toolbar look. They want to have a bigger border around the buttons. That is not provided by the standard control, at least when these apps were written (maybe it is now, I am not following these matters closely). What these apps are doing is playing with WM_NCCALCSIZE to restrict the client rectangle to something smaller than what remains when the system clips the true nonclient area. In the case of one of my test apps, this is done by subclassing (the Wine code is never called). Since GetWindowRect returns only the width and the height of the client area, and is setting the origin to 0 - 0, the custom client area appears higher that it is to WM_ERASEBKGND and the lower part of the window is not painted (toolbar in the case of the app I see) Now, I don't know yet how should be done the erasing of this custom nonclient area :-/ Gerard

Re: Does Wine's winhlp work?

I was about to ask the same question. My impression was that: i) 'winhelp' is completely non-functional ii) part reading help files only handles very old help files I implemented code to read somewhat newer help files, to degree that 'hlp2sgml' program is able to get some output, but since data structures used by graphical part are largly NOT filled, 'winhelp' itself has more reasons not to work (I have not sent patch to 'hlpfile.c' in case 'winhelp' actually can read some files). -- Waldek Hebisch hebisch(a)math.uni.wroc.pl or hebisch(a)hera.math.uni.wroc.pl

Does Wine's winhlp work?
by David D. Hagood 17 Aug '01

17 Aug '01

Is Wine's WinHelp program supposed to work? By that I mean, if I invoke that program with a Windows help file, is it supposed to be able to display the contents of the help file as Window's winhelp.exe would? I ask because 1) I have a program (DeLorme's AAA MapNGo) that uses WinHelp format documents for some of its normal operation, and 2) I have a WinHelp format file I'd dearly like to be able to access directly from Wine. When I try to launch Wine's Winhelp, it brings up a window, but the window is empty. If I go to File->Open and try to open a WinHelp file, I get the same result. Is there some setup I'm missing?

Refcounting in SelectObject
by Uwe Bonnes 17 Aug '01

17 Aug '01

Hallo, we discussed this January 2001 with no final outcome. Some application (gcprevue version 9) does 080673a0:Call gdi32.SelectObject(000011d4,000011d8) ret=5f485bb1 080673a0:Ret gdi32.SelectObject() retval=00000044 ret=5f485bb1 080673a0:Call gdi32.DeleteObject(000011d8) ret=5f487813 080673a0:Ret gdi32.DeleteObject() retval=00000001 ret=5f487813 080673a0:Call gdi32.BitBlt(000011d4,00000000,00000000,0000008c,000001a7,000009d0,00000000,00000000,00cc0020) ret=0048d1e6 and gets an XErrorEvent and fails to Debugbreak. Starting theapplication with winedbg still gets this error, but DebugBreak isn't executed and the application proceeds. The Windows Api explicitly tells for DeleteObject: Return Value: ... If the specified handle is not valid or is currently selected into a device context, the return value is FALSE. Windows Internals tells about some elements in GDIOBJHDR in debugbuild of windows and has pseudo code for incrementing some refrence counters in SelectObject. Appended patch tries to implement this scheme. The original discussion dissolved into nothing after Andi saw the need for such refcounting, but also mentioned possible resource leakage. Appended code tries to clean up better by: - Remembering an unsuccessfull DeleteObject by adding 0x8000 to the Refcount - Call DeleteObject in SelectObject when the RefCount of the released handle is 0x8000 - Decrementing the RefCount when a hBitmap is still selected into a DC when DeleteDC is called for that DC - Call DeleteObject in DeleteDC when RefCount is 0x8000 For some applications I tested, I always saw the delayed DeleteObject done after the refused DeleteObject in the first place. Is this approach better?

Problems building with extern inline functions in winebase.h
by Mike Bond 16 Aug '01

16 Aug '01

A couple days ago a number of inline functions were put into winebase.h. Since then I have been unable to build, using gcc 2.96-81 (RedHat). Apparently this version of gcc thinks that because there is an extern prefixing the inline, even though the function does in fact have a body, that the function really is external. Removing the extern, just having inline as one would do in C++, does not appear to work correctly either, and causes the function to appear as a exported symbol in all the object files that header gets included with, thus resulting in multiple definitions. I'm not sure what the correct solution would be, other than using the older function call method for this version of gcc. Perhaps I'm just missing some variant on the use of inline? -- TTFN MikeB

Stupid Winedbg question
by Bobby Bingham 16 Aug '01

16 Aug '01

Ok, I feel like an idiot for having to ask this, but it's my first time realing using the debugger. When wine starts the debugger on an exception, it opens it up in another xterm. Is there an easy way to copy it's output? The usual select and middle-click isn't working because it doesn't let me select the text to begin with. Thanks in advance for your patience. Bobby Bingham
