Re: [Mono-winforms-list] patch for enabling primitive XIM text input
Hi, Thanks for the details. Though I don't think I completely understand the second issue (XIM event order matter), I am persuaded. Your patch is in svn (along with my patch of course too). I'm also getting into libX11 code, so if you have pointers to relevant sources (probably in src/xlibi18n/* or modules/im/* ?) please give us them :) Atsushi Eno Doug Rintoul wrote: Atsushi Eno wrote: Hello, The first problem has to do with the tracking of the control, shift, and alt key. These keys will currently get stuck because if FosterParent filters the key release event, a key release event for these keys are never put on the hwnd Queue. For example, if you press CTRL-space to enable an IM, winforms still thinks the control key is still pressed, even after you release it. Using the left and right cursor keys to move around a input field will move a word at a time, rather than a letter at a time. Ah, good point! It should be fixed too. But I somewhat doubt if your change especially that KeyRelease event is always passed works fine. It could result in inconsistent key event processing (KeyPress could be filtered and KeyRelease always isn't) and such inconsistency trapped me couple of days. So, IMHO there should be some condition to determine whether to filter KeyRelease or not. Key filtering is totaling at the whim of the IM. If the the IM processes a key event it will tell the calling procedure the event is filtered. I am assuming you mean there should be a condition on whether we should process a key event in winforms even when the IM has filtered the event. If so, then you are correct. I think my patch currently works because few apps use key release events and so dual processing by both the IM and winforms is not an issue. However keypress events for mod could be a problem if the IM filters event. The keypress event would never be processed by winforms and thus the key state would never be registered. In this case we cannot do dual processing of all keypress events. So some condition needs to be determine as to when we pass the key press and key release events onto winform. Unfortunately, winforms currently relies on key press and key release events to track the modification key states. Perhaps it is enough to test if the event is a key press or a key release mod key event (alt, ctrl, shift, menu, etc) and then pass the event on to winforms for processing even if the IM filters the event. The only other alternative I can see is to redesign winforms so that it queries X for the current state of the modifier keys whenever it needs that information. The second issue has to do with the way that IME compose messages are handle. A bit of background is required here. I am one of the authors of KMFL (kmfl.sourceforge.net), which provides Tavaultesoft Keyman services to Linux. The way KMFL is designed is that KMFL can generate multiple compose messages in response to a single key stroke. The problem is that XIM does not use a FIFO to queue XIM compose messages, but a stack. So unless XIM compose events are processed immediately upon receipt, the recipient window will receive the XIM compose messages in the reverse order that they are generated. The fix is rather easy to implement. We just allow the application to process the keypress messages upon receipt rather than queuing a whole bunch and then returning. Note that the GTK XIM connector and the QT XIM interface work correctly with KMFL, so they implement a similar solution. I'm not sure what you meant here. Do you mean such event processing like below could happen? : - KeyPress for 'A' occurs, and then it is stored in X event queue ... well, stack ... as pending. - KeyPress for 'B' occurs, and then it is stored as pending. - XNextEvent() is called, and X returns KeyPress 'B' because it is not FIFO. This is sort of what happens. It has been awhile since I poked around the XIM code in X. I just went back to familiarized myself with the situation. The actual problem is with the XIM commit code in X11. Here is an example of what actually happens: 1. The user presses 7. The input method is to generate the string seven in response to this. The IM will actually generate each character as a separate compose event. I realize that in this case the IM could have generated one compose event containing the string seven, but this is not always the case. The way the kmfl engine is designed, it needs to be able to generate separate compose events in response to one keypress. 2. The IM calls the XIM commit callback to commit the first letter s 3. The XIM commit callback pushes the commit string on the IC commit info stack and then fabricates a KeyPress event with a keycode of 0 and pushes this event onto the event queue. Control is then transfered to winforms. 4. winforms receives the

Any thoughts on solving the tracking of the modification keys (control, alt, shift, etc)? Yes, what I applied was what you have provided (I believe): http://lists.ximian.com/pipermail/mono-patches/2008-March/113937.html For now I'm fighting against other preedit modes (preedit position and preedit callbacks), so let me think about it later. It seems that iiimx and/or atokx3 (Japanese commercial IM) has this kind of issue; it does not change keyboard's shift state, unlike scim(-anthy). I'm also getting into libX11 code, so if you have pointers to relevant sources (probably in src/xlibi18n/* or modules/im/* ?) please give us them :) These are the relevant sources. XIM is not an easy protocol to get your head around. I peppered the xorg code with printf statements to get a feel for the flow of processing.There is documentation at http://xorg.freedesktop.org/archive/X11R6.9.0/doc/PDF/. This is for version 6.9.0 but XIM has not changed much for version 7.3 Xorg rearranged the documentation for version 7 and so there are no PDFs readily available for the internals of 7.3. I have generated pdfs from the postscript file available with the source if your are interested. However you can download the PDFs for 6.9 have have virtually the same thing. The docs you would interested in are xim.pdf, XIMTransport.pdf and i18nFramework.pdf. There are other docs dealing XKB which might be useful but not specifically applicable to XIM. The docs are very low level. I have not really found a good overview of XIM on the net. http://xorg.freedesktop.org/archive/X11R6.9.0/doc/PDF/i18nFramework.pdf I've also generated xim.pdf from xim.ps ;-) Solaris IM implementation detail was also nice to read (it works on top of IIIMF and hence it does not always apply to my environment though) http://opensolaris.org/os/project/input-method/documents/SolIM_Impl.pdf When I solved the puzzle around preedit mode and XVaNestedList, I will have to come back to these docs.

A user interface designer is not like a drawing tool. The controls you put in the design surface must look and behave exactly like the controls at run-time.

The attached patch contains further improvements to the perf or ToString of primitive types. The perf gain is due to two changes 1.

Hello Sharique. Something like that is what I've been thinking with MonoHotDraw [1].

The other one is for make some improvements to Lunar Eclipse, the XAML editor. In both cases my plan is to build a reusable framework for writing graphical editors that use structured graphics. There are plenty of cool stuff that could be made with a framework such that: * A Class Designer for MonoDevelop. * A DataBase Graphical Desginer for MonoDevelop * A Dia replacement with all the cool features that Moonlight can offer. * An UML Editor (Actually, the MonoHotDraw project has been written as a part o the MonoUML project) * A Mind map editor. How could would be a mind map editor for tomboy. Or a moonlight collaborative mind map editor to be used inside a wiki engine. * Improvements to Lunar eclipse.

[Mono-list] .NET Remoting and Hashtable
Hi,
we work on a project of distributed system where we use the technology
dotNET Remoting. But we have there a small issue.
We have two types of nodes there, managers and storages. They both use the
same method (the method is in dll file - manager and storage have the same
copy of this file).
The method is:
public void UpdateLastSeen(Node n)
{
if (lastSeen.ContainsKey(n))
lastSeen[n] = DateTime.Now;
else
lastSeen.Add(n, DateTime.Now);
}
// Node n - is our own object
// lastSeen is hashtable (key is our own object Node, value is DateTime)
Problem:
The both nodes - managers and also storage peridiocally call this method,
while one of them works well, another one does somethig different with the
same code.
For example the topology is point-to-point, one manager, one storage.
Storage updates active status of the manager well, but manager can't
recognize that it has is connected stil the same node - the same storage.
The result is that the manager does not overwrite the time of last seen of
the node storage, but by timer click it adds allways a new entry into the
hashtable. With the same code storage works great.
No idea where the problem could be, maybe the copy of the object Node is not
the same like in the object stored in the hashtable??
Hope that someone will understand what we tried to explain;) and help.
Thanks a lot

michal kohut

It is definitely not the same object, so you have to implement Node.GetHashCode() to establish a consistent identity that does not rely upon Object.GetHashCode. Note that if Node is a MarshalByRefObject, GetHashCode won't be called remotely. This means that overriding GetHashCode has no effect in other app domains than the creator domain.

Re: [Mono-list] .NET Remoting and Hashtable
Hi!
Does your Hashtable sit in a MarshalByRef class or a [Serializable] one?
If the latter is the case then each connecting node works on its
separate copy.
Are you positive yor class is marshaled as a singleton rather than
single-call?
Other than that, only putting: lastSeen[n] = DateTime.Now; in the
method body will be a faster solution.
You should also consider using lock(lastSeen) if more than one client
can be connected at a time.
Cheers!

Hi,
we work on a project of distributed system where we use the technology
dotNET Remoting. But we have there a small issue.
We have two types of nodes there, managers and storages. They both use the
same method (the method is in dll file - manager and storage have the same
copy of this file).
The method is:
public void UpdateLastSeen(Node n)
{
if (lastSeen.ContainsKey(n))
lastSeen[n] = DateTime.Now;
else
lastSeen.Add(n, DateTime.Now);
}
// Node n - is our own object
// lastSeen is hashtable (key is our own object Node, value is DateTime)
Problem:
The both nodes - managers and also storage peridiocally call this method,
while one of them works well, another one does somethig different with the
same code.
For example the topology is point-to-point, one manager, one storage.
Storage updates active status of the manager well, but manager can't
recognize that it has is connected stil the same node - the same storage.
The result is that the manager does not overwrite the time of last seen of
the node storage, but by timer click it adds allways a new entry into the
hashtable. With the same code storage works great.
No idea where the problem could be, maybe the copy of the object Node is not
the same like in the object stored in the hashtable??
Hope that someone will understand what we tried to explain;) and help.
Thanks a lot

michal kohut

Only if you don't include Mono.Posix.dll with your app. :-)
If you don't want it to blow up, it should work to move the Ustname and

that method will never be jitted on Windows.
