(I wish Microsoft would be consistant) Just for the record it is clearly more complex than that. I guess since Microsoft wrote it we can trust Spy++ a little. I have seen spy++ declare that a "tooltips" class window (style 0x84800000/00000088) has style WS_OVERLAPPED whereas a "tooltips_class32" class window (style 0x84800003/00000088) doesn't. Bill

ListView Patch
by Steve Whine 15 Aug '02

15 Aug '02

Hi all, I should maybe have posted this to the patches list, but I would like your comments first. I have fixed a few problems with the ListView control when using icons larger than the sizes returned by the system metrics. This (attached) patch also causes LISTVIEW_Arrange (which was previously a stub) to call the LISTVIEW_AlignTop/Left when appropriate. Please let me know what you think. This is my first time doing any of this, so let me know what I'm doing wrong/right. Cheers Steve

ListView Issues
by Steve Whine 14 Aug '02

14 Aug '02

Hi, I've just started looking into getting a project of wine running on Linux via Wine, and I'm very impressed so far! However, there are a few (mostly minor) problems with the ListView control: - When using icons bigger than the sizes returned by SystemParametersInfo(SPI_GETICONMETRICS), the text for the items is not displayed correctly at the bottom of the icon. - When running a program created by C++ Builder 5, clicking on an item in the listview causes an access violation in C++ Builder's VCL library code - it is obviously getting passed an unexpected value. - The amount of text displayed is often far less than is displayed in Windows, making the listbox difficult to use. I have been looking into the ListView code and have hacked a fix for the first and third problem, but I am having a little difficulty understanding the code - the LISTVIEW_INFO struct has both an nItemWidth/nItemHeight pair describing the width/height of each item, and an iconSpacing SIZE struct that seems to do the same. What is the difference in these, where should one be used and where should the other be used? Is anyone actively maintaining the listview code, or should I just carry on hacking until I'm happy with it, and post the changes here? I have created a small test program to demonstrate these problems which I can post if anyone is interested. I must say it's very nice to be able to wade into the code to fix these problems myself rather than waiting for someone else (not) to do it!

The documentation on http://msdn.microsoft.com is quite accessible. If you know on which API you want some info, just type it's name in the search box, and you'll get a bunch of results. In my experience, some of the top results are often about WinCE, just skip them. Vincent

what's with WS_OVERLAPPED?
by Medland, Bill 14 Aug '02

14 Aug '02

(Regarding the whole issue of windows reparenting) MSDN keeps going on about windows with the WS_OVERLAPPED style. However surely (since WS_OVERLAPPED=0) every window has such a style these days. Is there something I don't understand? Bill

I mean that (statically, according to Spy++, when the popup form is active) 1. The ThunderRT6FormDC which "is" the form has style WS_OVERLAPPED, no parent (i.e. the desktop) and owner is the ThunderRT6UserControlDC 2. The ThunderRT6UserControlDC which, I believe, "is" the ocx, has style WS_OVERLAPPED and no owner, but its parent is an ATL window 3. That ATL window's parent is another ATL window 4. That second ATL window has no parent. (So, by generations I am talking about the static parent relationship, independent of how it came to be; c.f. old people adopting young ones resulting in skipped generations) > > -- > Dmitry. > > > And I have just noticed the lie in MSDN. It says (Platform SDK - Windows User Interface - Owned windows) that once the window has been created, with an owner, you cannot change the owner. That has to be wrong. A propos. I think there is a related error in CreateWindowEx. At least it disagrees with MSDN. If passed a parent If this is a child set parent to the paremt passed in and leave the owner 0 else set the parent to the desktop and the owner to the GA_ROOT ancestor of the window passed in. Surely it should be (according to MSDN) if passed a parent if style includes WS_OVERLAPPED or WS_POPUP assert style does not include WS_CHILD if the parent is itself WS_OVERLAPPED or WS_POPUP parent is desktop and owner is the parent passed in else if the parent is a WS_CHILD then parent is desktop and owner is the GetAncestor(parent, GA_ROOT) else assert false? else assert WS_CHILD owner is 0 and parent is as specified Comments? One datum of use. In our particular case this fits; the ThunderRT6FormDC is WS_OVERLAPPED with no parent. Its owner is the ThunderRT6UserControlDC which also is WS_OVERLAPPED but has a parent. Bill

It correctly shows paerent/owner for my test application playing with SetParent/SetWindowLong. It seems that Windows always sets 0 in the parent field if the parent is desktop.

Now I don't understand your terminology. parent - child - sibling are the termings in the Windows world. Who of them was born earlier matters only when Z order and visibility are taken into account (and can be easily changed). -- Dmitry.

Careful. In our particular case, according to Spy++ the owner of the ThunderRT6FormDC is a third-generation window. viz. the actual window requested, not one of its ancestors. i.e. I see the call to SetWindowLong (30056 (The ThunderRT6FormDC), -8, 10046 (The ThunderRT6UserControlDC)) I guess an important point here is that in our case the Visual Basic is an OCX sitting inside a container and so the ThunderRT6UserControlDC is not first generation. > > -- > Dmitry. > > > > Hope this helps.

If you select the memo field > then the Category field gets cleared. Well, after a day of wading through a whole lot of --debugmsg +all logs, I've figured out what's going on with this... EDIT_WM_GetText (in controls/edit.c) is "blindly" setting the last byte of the string buffer being past to it to NULL: textA[count - 1] = 0; /* ensure 0 termination */ Apparently, in this particular case, the buffer size (the 'count' veriable) is not correct, and the location of textA[count - 1] just happens to correspond to the first byte of the Category field, which (obviously) CHANGES IT TO A NULL STRING! Voila! Now, since I have just found this, I have not had a chance to determine of the erroneous value of "count" is a bug in Wine, or in Quicken! Doing so may take an awfully loooooong time, particularly since I don't have the source for Quicken. (Since this does not seem to be a pervasive bug, I'm suspecting Quicken...) So, here's what I see as my choices... 1) Forget the origin of the bug, and change EDIT_WM_GetText to only set the last byte to a NULL only if there is not a NULL byte prior to [count - 1]. I'm guessing the most efficient way (I'm no C guru) would be to change the line to something like: if (strlen(textA) >= count) textA[count - 1] = 0; If this is reasonable, the question that I would have is "What functions should I use in place of the strlen() above [for A and W strings] (or is strlen() good enough for both)?" 2) Take some time to try to track down if the bug is Wine related. I'm willing to spend a day (maybe two) on this, but my gut tells me it's futile. Obviously, if I find a related Wine bug, I'd fix it, which indirectly would fix this issue. But if I don't find a related bug, I guess I would have to revert to (1) anyway... Suggestions?? Comments?? Carl

Just an FYI but this bug is also what is reported under bug#825 (and 961). I have indicated under 825 a hack which prevents the problem from occurring, and there was a recent discussion where Alexander indicated it may not be correct to actually call SetParent for GWL_HWNDPARENT, which is exactly what my hack changes. Note bug#825 also has an attached testcase already Jason

can windows be reparented?
by Medland, Bill 13 Aug '02

13 Aug '02

Can anyone help me with this? I am trying to track down a problem with our software, relating to Visual Basic and its forms. We launch a container executable which then loads one of hundreds of OCXes (compiled from Visual Basic). One of the things that then happens within those OCXes is that they use the Visual Basic "load" instruction to load a different form in a modal way. Under Windows the form (which is generally larger than the original OCX form) comes up on the main display, with full usability (you can click on windows etc). However under Wine it comes up within the client area of the original and only responds to keyboard input. (Luckily Alt+C maps to the Close button so we can close it). If I use Spy++ under Windows I can see that when the "popup" form is up then its parent is 0 but its owner is the ThunderRT6UserControlDC under the ATL window that is the container. Under Wine if I watch the CreateWindow calls I see that the ThunderRT6FormDC parented by the ThunderRT6Main and the ThunderRT6UserControlDC parented by a STATIC under the ThunderRT6Main. Unfortunately I know of no way to see what parent was originally specified under windows. I presume that it is unlikely that the parentage was altered after the windows were created. Does anyone know differently? Anyone now what might be going on? Bill

Bug #931
by Dusan Vujosevic 13 Aug '02

13 Aug '02

I seems that the problem I noted in bug #931 goes away when "PerfectGraphics" is set to false (????). I tracked the problem down to implementation of PATINVERT in BITBLT_InternalStretchBlt() (in graphics/x11drv/bitblt.c). It check whether 'perfect_graphics' is on and if it is it actually doesn't do the drawing: case PATINVERT: /* 0x5a */ if (perfect_graphics()) break; Maybe I'm missing soemthing here but I think that test should be: case PATINVERT: /* 0x5a */ if (!perfect_graphics()) break; That would give a more logical behaviour where there would not be any drawing errors when "PerfectGraphics" is set to True. (There are other spots where this is used in similar fashion) Another question is why have the "PerfectGraphics" option at all when it produces drawing artifacts? D.

Incomplete support in Win32
by Shachar Shemesh 13 Aug '02

Hi all, As you may know (I make a lot more noise than actual work), I am trying to implement BiDi support for WINE. The most promising place to start seemed to be GetCharacterPlacement, that does everything even remotely BiDi related. The most immediate thing to do was to call GetCharacterPlacement from ExtTextOut in order to do the BiDi rearrenging. In typical MS fashion, however, it seems that this will not work. Despite the fact that you are supposed to be able to call GetCharacterPlacement once, and then call ExtTextOut with the result as many times as necessary (speeding up the process, and suggesting that GetCharacterPlacement can do anything ExtTextOut can do), it seems there is one thing that ExtTextOut is expected to know how to do, and GetCharacterPlacement does not know. For those who are really interested, this is specfying the base directionality of the paragraph. I am pretty sure the way Windows implements this is by having a common parent function used for reordering by both ExtTextOut and GetCharacterPlacement. I think such an arrangment is awfully crude. I was considering an alternative solution, and would like your opinion. What I thought of doing was adding a bit to the flags GetCharacterPlacement gets, which says "right to left paragraph, if you'll be so kind". My question is - how acceptable is such a behaviour. Is that a huge no-no, or is that a harmless little tweak? It goes without saying that I will document the fact that this is a WINE only flag, and that there are unused bits in the GetCharacterPlacement current flags set. Another alternative I was considering was to add a directional push at the start of the string in order to achieve this without changing the algorithm. The problem is that I am not sure what affect this will have on the reordering, not to mention the fact that I will then need to copy and widen the string inside ExtTextOut, which is an inconvinence to say the least. Your opinios, please. Shachar
