However, have you verified that the patch doesn't regress Gert's test case (not the original reporter's one) in bug 323234 (which rev 101225 was supposed to fix)? -- Kind Regards, Ivan N.

[Mono-winforms-list] Plans for Cairo intergration / will ever be cairo usable with winforms?
I have an application written in c#, it is process visualisation toolkit. I have tried to run it on the mono on linux. There were some problems, but everything was fixable, except for cairo. I use cairo for all drawing. On windows I can use win32surface and draw onto it. I don't want to use GDI+, because I know cairo pretty good and it is multiplatform. Problem is, that I can't create win32surface on mono on linux. May be I'm missing something, but I think that win32surface is supported only on windows now. I have worked around this by rendering onto ImageSurface, then writing to PNG file and loading it back with GDI+, but it has big overhead and is very slow. Are there any plans to support any cairo surface on WinForms? Or is here any workaround? (I don't want to use GDI+ api) Anyway, mono is really great project and there must be hard work behind it.

[Mono-winforms-list] [PATCH] Avoid sending MouseEnter messages when clicking
Hey Ivanz,
The attached patch reverts a check in XplatUIX11.GetMessage method,
specifically handling the X11 EnterNotify message generated when
clicking a control (rev 101225).
Basically when a control is clicked, EnterNotify events are generated
for the container form and the control being clicked. Usually when we
get this event we generate a WM_MOUSE_ENTER message, but in this case we
don't need it, since it's not real pointer motion.
That's why, when the EnterNotify event tell us that it's a not a real
motion event, we have to ignore it, no matter the value of the
window/hwnd (right now, when clicking any control, MouseEnter/MouseMove
events are generated for the containing form, which is obviously wrong).
Hopefully that was clear ;-D
Carlos.

Re: [Mono-winforms-list] DataGrid
Probably it's a regression. Would you mind filling a bug report? This way we can track the error with the details. Carlos.

[Mono-winforms-list] DataGrid
Do anyone of you use a DataGrid in your applications? Does it work? I tried various applications on various systems and it never works. I always get the "IndexOutOfRangeException" when I try to add a new row. Only in the ReportBuilder compiled application founded in the vmware image downloaded from this site I've seen it works. But if I compile the source, it doesn't work.
