I pasted the code badly.. maybe I can simplify my question a little as
would really like to get this working:
Basically if you check out the piece of the tutorial here:
http://www.mono-project.com/GtkSharp_TreeView_Tutorial#Controlling_how_the_model_is_used
 it describes how to set up a TreeView so that it is bound to an
object containing your data.  When the data in your object changes, so
does the TreeView thus allowing you to update the data easily.
My problem is that the example uses a ListModel rather than a
TreeModel as in the previous section
(http://www.mono-project.com/GtkSharp_TreeView_Tutorial#Your_first_TreeView).
If anyone has any examples of how to do this above using a TreeModel I
would greatly appreciate it.

I guess I don't understand the question.  Where did you get "ListModel"
from?  It isn't anywhere in the provided examples,  you attach a
ListStore to a TreeModel, and just have a TreeView with only one
'level'.

Gtk.TreeView tree = new Gtk.TreeView ();
Gtk.ListStore musicListStore = new Gtk.ListStore (typeof (string), typeof (string));
... 
tree.AppendColumn ("Artist", new Gtk.CellRendererText (), "text", 0);
tree.AppendColumn ("Title", new Gtk.CellRendererText (), "text", 1);
musicListStore.AppendValues ("Garbage", "Dog New Tricks");
tree.Model = musicListStore;  <-- Model is the the ListStore

ListStore & TreeStore should be able to be used pretty much
interchangeably AFAIK,  depending on the need of the application

Admittedly,  TreeView is an intimidating beast.

Here is an example. I think I understood your problem:

------
using System;
using Gtk;

	}
	
	protected void OnDeleteEvent (object sender, DeleteEventArgs a)
	{

Subject: [Gtk-sharp-list] Preventing Dups In a ListStore
Message-ID: <1199483646.6049.12.camel@WM_ADAM1.morrison.iserv.net>

I have a ListStore - 
panelStore = new Gtk.ListStore (typeof (Whitemice.ZOGI.Entity));
 - used to hole a collection of participants.  In the UI the user can
search for additional participants in a dialog which then puts the
selected participants into the list;  all good.  But what is the
simplest / most efficient way to prevent dups in a ListStore?  I don't
want to have the same entity added twice, if it is already there I'd
prefer to just ignore the operation.

Like -

if (!(panelStore.Contains(entity))) panelStore.AppendValues(entity);

 - but, of course, there is no Contains [or equivalent] method in a
ListStore.  And the ListStore doesn't seem to care about storing
multiple references to an object.

Do I need to iterate the contents every time I add an object in order to
prevent dups?  Or is there some kind of short-cut that I'm missing?

AFAIK you'd have to iterate it (though ForEach will simplify this). Of
course, that's what a Contains () call would do anyway -- if you want
O(1) contains calls, you'd need a hashtable, but a list obviously
needs... a list. Depending on the details of the code, storing a
separate hashtable for these lookups might or might not be more
efficient.

Alternatively you could implement a TreeModel interface around another
collection, but that would require GTK# from SVN for GInterface
support.

Yes, that's the problem. It would be O(n) for a na?ve approach.

Another option (besides hashtables, trees, etc) would be to store an
additional field on each entity stating that it was already included
or not, but of course this depends on how your code works, as it may
be not possible.

Hi folks,

for the ongoing effort to develop data-bound Gtk# objects, I have some remark 
when it comes to data-binding a TreeView:

When storing a tree data structure in an RDBMS, you would normally define a 
table like this:

CREATE TABLE treestore (
	id		INTEGER NOT NULL PRIMARY KEY,
	super_id	INTEGER REFERENCES treestore (id) ON DELETE CASCADE,
	name	VARCHAR (35)
);

This means: A line in this table, which has super_id = NULL, represents a root 
node, otherwise it would represent a "branch" (if some other line points at 
it with its super_id entry), or a "leaf" (otherwise).

When pouring such data into the TreeView, you start with root nore #1, then 
with the first child node of root node #1, and so on...recursively. Once you 
have added all leafs, you would return to the level just above it (a node can 
have more than one child) and at last to the root level to continue with root 
#2, if it exists:

+ root_1
+- branch_11
|+- leaf_111
|+- leaf_112
+- branch_12
|+- leaf_121
+ root_2
[...]


Nowadays, you use the TreeView, associate a TreeStore with it as a model, and 
then recursively call the AppendValues() method on the TreeStore, using the 
TreeIter object returned by this method. The two big challenges I have 
expected so far are:

*) The result set must come pre-sorted from the RDBMS (in the manner stated 
above), otherwise my C# app would have to scan through the result set, which 
consumes a lot of client-side computing time. Pre-sorting is easy with two 
hierarchy levels (root, leaf), but with three or four levels, you have to 
rely on stored procedures on RDBMS side, which are normally NOT portable.

*) The TreeIters of all objects have to be stored in a collection and, when 
some node gets a child node, retrieved.

Shall those of you who are now involved in coding the data-bound Gtk# widgets 
use this as a starting point. Comments and questions are, of course, always 
welcome.

Regards
Jacek Ru?yczka

I've made a, probably rather crude, solution by extending ListStore.  I
had hoped to just override AppendValues but those methods aren't
virtual.  So I went with the keep-an-index approach.

http://consonance.googlecode.com/svn/trunk/Whitemice.ZOGI.Gtk/General/Lists/EntityStore.cs

Comments welcome.

An object can appear in perhaps dozens of lists, so that wouldn't really
work.

When using a TreeView to display data from an RDBMC I think it is much
more common that the subordinate entries are the result of a foreign key
relation (join or secondary select).

You may want to make it generic instead of specific to Whitemice.ZOGI.Entity.

This is what I have in fact sketched here. Typically, when you have a 
hierarchy of categories, you would add an FK column pointing to the PK column 
in the same table.

Just a heads up for whoever is thinking about doing this. I've written
stuff like this in both python and C and noticed some interesting
results.

First of all, I went the route of writing a custom GtkTreeModel.  This
way I had full control of tree iteration.  You will probably want to
do the same.  Especially since this allows lazy loading.

For example: For the iter data, you could store the rows offset.  In
PostgreSQL and SQLite, using the row OID works great as it is the
fastest way to access any record.  However, using a system that allows
you to determine the next rows Iter data without a new query is
probably a good idea. If I remember correctly, I got my best
performance by mixing the two ideas; Batching queries to get the next
10 rows OIDs.

I also noticed that for some reason, when setting the model, a
GtkTreeView will try to scan the entire result set.  I think this is
actually a GtkCellRendererText trying to figure out sizing but I
haven't looked at it too closely.

You also may want a tunable cache to lower the number of queries.  I
used a LRU which worked pretty decently . Just remember to expire
values on updates.

Food for thought.

The reason why I used a pre-sorted query is that the sorting function for the 
tree view nodes is then executed in the RDBMS, which in turn lowers some CPU 
burden on the client side. The drawback of my solution, of course, is that 
it's no longer DBMS-independent because of the stored procedure. :-(

DANGER: The newest PostgreSQL releases assign OIDs to individual rows only 
when you request it in the CREATE TABLE command.

That's a good thing as you never know what the LAN performance of your 
customers is. :-/

Subject: [Gtk-sharp-list] Gnome Vfs Bindings question
Message-ID: <1199820107.9228.11.camel@station-13.ad.isillc.com>

Long and short is that I'm trying to get the MIME type from a known uri
string and the Gnome.Vfs.FileInfo class found in gnome-vfs-sharp looked
to be the ticket.  (I'm wanting something that will/should work under
both windows & linux.)

Unfortunately, when I try to run the following code:

Gnome.Vfs.FileInfo info = new Gnome.Vfs.FileInfo(fileUri,
FileInfoOptions.GetMimeType);

where fileUri is a string version of the uri

I get a VfsException that says Invalid parameters.  The inner exception
is set to null.

I did see an example floating around the Net that had
FileInfoOptions.Default | FileInfoOptions.GetMimeType, but trying that
gave the same results.

Does this mean that GetMimeType is not actually supported or am I
missing something?

I'm running Gtk# for Windows v2.8

Thanks!

I'd hope that any Gtk# data-binding would be binding to an ADO.Net
DataSet/DataTable and not dealing with any specific providers.
DataTable provides a primary key property,  IMO, nothing should depend
on anything except that;  that and the ChildRelations / ParentRelations
seem adequate to automatically fill a TreeView;  although I still doubt
anyone [in practice] is actually using a TreeView in such a
straight-forward way - Entities, Labels, and ComboBoxs probably, but
TreeViews I see are usually of some kind of composite/tabulated data.

Hi,

I've recently noticed some build errors for monodevelop.  This is
building on suse 10.1 with gtk# 2.8:

/MonoDevelop.Ide.Gui.Pads/ErrorListPad.cs(230,33): error CS0104:
`Action' is an ambiguous reference between `System.Action' and
`Gtk.Action'

With this change in place, am I still going to be able to build on suse
10.1 with gtk# 2.8?  Will gtk# 2.8 need an update to reflect this
change?

FYI, the reason I build on 10.1 is for the binary linux installer.  Even
still, I assume we still want to support some older distros that are
still in service?

Message-ID: <8ed5cbac0801110707r6699e678j2d230dbe408b8d4b@mail.gmail.com>

Hi all,

My (Gtk#) GUI thread is non-responsive and I am hoping to find a
profiler or something else that will help me figure out why that is.
I am creating a worker thread (a.k.a. long running process) as
described below.  Note that I set the priority to Lowest for my worker
but it seems to take over the processor anyway.

Are there any obvious tips I can try to follow?
Is there a profiler that will run on Linux?  I run Mono on OpenSuse
10.2 and all the C# profilers seem to be written for Windows.
I tried using the profiler that is part of Mono but I don't know how
to read (analyse) the output.  Is there any help?

Evaluator eval = new Evaluator();
ThreadStart ts = new ThreadStart(eval.Run);
Thread evalHost = new Thread(ts);
evalHost.IsBackground = true;
evalHost.Priority = ThreadPriority.Lowest;
evalHost.Name = "Foo";
evalHost.Start();
System.Threading.Interlocked.Increment(ref workersLeft);


Thanks,

Vlad

Have you read http://mono-project.com/Responsive_Applications yet? gtk+
is thread aware, but not thread safe. In order to behave properly, you
can only mess with GUI bits from within the gtk+ mainloop context. The
above URL has a lot of pointers for approaches for doing this properly.

Compilation was successful but upon running the application and as the
save dialog box showed,the filechooser widget was not present and an

I would like users of my application can drop content of a spinbutton to

I can do it in code but in this particular case it's not really a very

Anyone has an idea?

Subject: [Gtk-sharp-list]  Check Process state in an GUI app
Message-ID: <14982013.post@talk.nabble.com>


hi,
I'm currently trying to write a very very simple front-end for ffmpeg with
gtk#.
My Code looks like this:

First I check if a file already exits with File.Exits(path)
MessageDialog -> Overwrite YesNO.

Then the I start ffmpeg with Process.Start(). 
Then I want show a MessageDialog if the process finished so I did it like :

while(!proc.HasExited) {}
MessageDialog -> "Encoding finished";

This is working good but this causes some bugs. E.g: If I do Overwrite it
"yes". The MessageDialog isn't destroyed until the process finished. If I
delete this while {} it's working correct but the Message appears
immediately and not after the process hast Finished. Using if is also not
that good I suppose :/

Any solution? Thx in advance :)

Your loop is hanging the GUI thread, by not allowing GTK to return to
its main loop (in which it does all the drawing etc).

Handle the Process.Exited thread instead:

proc.Exited += delegate {
    MessageDialog -> "Encoding finished";
};

Hi,
thank you very much for your help. I tried both of you methods and it's
working really great but there is one thing left I that should work. With my
old (buggy) version the Files from the Treeview were removed automatically
when the encoding was finshed. That means. I have a treeview with let's say
3 titels and after the first title is finished with encoding it should be
removed to only 2 are remaining and so on ...
Any chance that I can manage it like in the past with?

		this.menuListStore.GetIterFirst(out iter);
		this.menuListStore.Remove(ref iter);

Hi,
thank you very much for your help. I tried both of you methods and it's
working really great but there is one thing left that should work. With my
old (buggy) version the Files from the Treeview were removed automatically
when the encoding was finshed. That means. I have a treeview with let's say
3 titels and after the first title is finished with encoding it should be
removed to only 2 are remaining and so on ...
Any chance that I can manage it like in the past with?

		this.menuListStore.GetIterFirst(out iter);
		this.menuListStore.Remove(ref iter);

You still can, you just need to do this from the GUI thread.  We will
need more information about the circumstances you are doing this under
to help.  Can you paste your code?

Sure, no problem. Though I don't know if I should post the whole one ore not
^^. anyway. here it is :

In my eyes it's very ugly code and beside my problem here I would appreciate

Thanks, that helped a lot.

Basically, you are going to have to change your entire code flow and
break it apart a bit.  You are going to need one method that is
responsible for checking your preconditions (popping a dialog to
confirm, etc) and starting the process on one file.  Then in the
Exited handler you need to start the process on the next file.  So
something like this pseudo-code:

OnConvertClicked():
    ProcessNextFile();

ProcessNextFile():
    CheckPreconditions;
    StartProcess;
    AttachEventHandler -> Application.Invoke -> OnProcessCompleted;

OnProcessCompleted():
    RemoveProcessedFileFromList;
    If MoreFilesToProcess
        ProcessNextFile();

Something like that.  You may want to make your window insensitive
during the processing too, or at least any buttons that can change the
state of your application.  You don't want people modifying the file
list while you are processing, for example.

You are helping me a lot. Thank you very much. Yeah as you can see I already
tried to set all buttons,.. insensetive. Thx for you posted solution but I'm
totally new to this. Can you give me a more specific code? Unfortunately the
docs are really really *unfilled* I wouldn't ask

Hi everybody

I need some help, i am creating an application using mono (obvious :P  
) and i need to create have a widget with background image and on top  
of it will be a table layout. After that i need to add this widget on  
the main window. I already solve the problem for the background image  
but when its loaded it fill all the main window background too. so  
what i would like to have is the new widget as a utility bar.

My code for the backgound that i want to attach to the main window

public partial class frmFretboard : Gtk.Window
	{


		public frmFretboard():
				base(Gtk.WindowType.Popup)
		{
			this.Build();

//			Gtk.Style wndStyle;
//			wndStyle = new Gtk.Style();
			this.Style.BgPixmap( StateType.Normal );
			try
			{
				Gdk.Pixbuf image = new Gdk.Pixbuf( "guitarfretboard.jpg" );
				Gdk.Pixmap pixmap, pixmap_mask;
				image.RenderPixmapAndMask( out pixmap, out pixmap_mask, 255 );
				int width  = image.Width;
				int height = image.Height;
				this.Style.SetBgPixmap(StateType.Normal,pixmap );
				this.SetSizeRequest(width,height);
				this.Resize(width,height);

			}
			catch(System.Exception e)
			{

				MessageBox msg = new MessageBox();

				msg.Show(e.Message);
				Application.Quit();
			}
		}


	}

The next code is the widget i created where the first will be attached  
  and then this one will be attached to the main window.
public partial class FretBoard : Gtk.Bin
	{
		private Widget fretboard;

		public FretBoard()
		{
			this.Build();
			Added += new AddedHandler (OnWidgetAdded);
			SizeRequested += new SizeRequestedHandler (OnSizeRequested);
           	SizeAllocated += new SizeAllocatedHandler (OnSizeAllocated);
//			fretboard = new frmFretboard();
			this.Add(new frmFretboard());

		}

		public void SetStringPressed( int pos_x, int pos_y )
		{

			//tblFretboard.Attach();
		}


		void OnWidgetAdded (object o, AddedArgs args)
		{
			fretboard = args.Widget;
		}


	    void OnSizeRequested (object o, SizeRequestedArgs args)
		{
			if (fretboard != null)
			{
                int width = args.Requisition.Width;
                int height = args.Requisition.Height;

                fretboard.GetSizeRequest (out width, out height);
                if (width == -1 || height == -1)
                     width = height = 80;
                SetSizeRequest (width , height );
           }

      	}

      //
      // Invoked to propagate our size
      //
      void OnSizeAllocated (object o, SizeAllocatedArgs args)
      {
           if (fretboard != null){
                Gdk.Rectangle mine = args.Allocation;
                Gdk.Rectangle his = mine;

//               his.X += pad;
//               his.Y += pad;
//               his.Width -= pad * 2;
//               his.Height -= pad * 2;
                fretboard.SizeAllocate (his);
           }
      }

hi,
I'm currently trying to write a very very simple front-end for ffmpeg with
gtk#.
My Code looks like this:

First I check if a file already exits with File.Exits(path)
MessageDialog -> Overwrite YesNO.

Then the I start ffmpeg with Process.Start(). 
Then I want show a MessageDialog if the process finished so I did it like :

while(!proc.HasExited) {}
MessageDialog -> "Encoding finished";

This is working good but this causes some bugs. E.g: If I do Overwrite it
"yes". The MessageDialog isn't destroyed until the process finished. If I
delete this while {} it's working correct but the Message appears
immediately and not after the process hast Finished. Using if is also not
that good I suppose :/

Any solution? Thx in advance :)

Message-ID: <10b6506f0801231222g37be99bao64889100ff913aff@mail.gmail.com>

Hello

This is the first time I post anything to this malling list and this is my
problem.

When I do ./configure --prefix=/usr I get this output:

---
Configuration summary

   * Installation prefix = /usr/
   * C# compiler: /usr/bin/mcs  -define:GTK_SHARP_2_6 -define:GTK_SHARP_2_8
-define:GTK_SHARP_2_10 -define:GTK_SHARP_2_12

   Optional assemblies included in the build:

      * glade-sharp.dll: yes
      * gtk-dotnet.dll: yes

      NOTE: if any of the above say 'no' you may install the
            corresponding development packages for them, rerun
            autogen.sh to include them in the build.

   * Documentation build enabled: yes
      WARNING: The install prefix is different than the monodoc prefix.
               Monodoc will not be able to load the documentation.

When I make I get this error after a summary:

How can I compile this? To run the SVN version of MonoDevelop I'm getting
error that someone told me on #MonoDevelop that was resolved in GTK-Sharp
last version.

How can I compile it?

I'm assuming you meant ./bootstrap-2.12 --prefix=/usr.  BTW, installing an
svn version of any software into /usr is a tremendously bad idea.

No idea what's going on there.  I just checked out a clean svn trunk
instance, ran bootstrap-2.12 and my make succeeded.

Subject: [Gtk-sharp-list] Announcing Preview Release for Gtk 2.12 and Gnome
	2.20 bindings
Message-ID: <1201214485.1444.304.camel@t61p.site>

We are announcing the first public preview release of bindings for the
Gtk 2.12 and Gnome 2.20 APIs.  

These releases are not API-stable yet, but are sufficiently mature to
begin testing against.  Anticipated API adjustments are expected to be
minimal at this point but might occur until we reach the stable 2.12.0
and 2.20.0 versions.

The gtk-sharp package contains bindings for glib, pango, atk, gdk, gtk,
and glade.  The API versions bound correspond to the versions shipped in
the GNOME 2.20 platform release set.

The gnome-sharp package binding set has changed with this release.
Remaining in gnome-sharp are art, gnomevfs, libgnome, libgnomeui,
libgnomeprint, libgnomeprintui, libpanelapplet, libgnomecanvas, and
gconf bindings.

The gnome-desktop-sharp package contains updated versions of the
gtkhtml, rsvg and vte bindings previously shipped in gnome-sharp, as
well as new bindings for libgnome-desktop, libnautilus-burn, and
libwnck.  We expect to add gtksourceview2 bindings as well prior to the
final release.  Bindings shipped in this package are not guaranteed to
be API stable since the underlying libraries are not guaranteed API
stable.  Attempts will be made to maintain compatibility where possible,
using policy assemblies.  When API compatibility is broken in underlying
libraries, the associated bindings will be parallel-installable with
prior versions.

Testing packages for openSUSE 10.3 and Fedora 8 can be found at:

http://download.opensuse.org/repositories/home:/mkestner/

Source tarballs are available from ftp.gnome.org.

We expect to move rapidly toward the 2.12 and 2.20 final release, with
possibly one more preview depending on the number of issues identified.
Issues can be reported to bugzilla.novell.com module gtk#.

Subject: [Gtk-sharp-list] Gtk.AboutDialog
Message-ID: <m3odba56ty.fsf@pc.local.netz>

Hello,

i wrote a small Gtk# program which works fine under Debian, Ubuntu and
Windows. Now i have tried it with Fedora where the close-button of
Gtk.AboutDialog doesn't work.

Since the close-button works with Tomboy at Fedora i have looked into
the source code of Tomboy and found the difference.

Tomboy has a aboutDialog.Destroy() statement after the
aboutDialog.Run() statement. If i add this statement to my code the
close-button works on Fedora too.

But i wonder what is the correct behaviour? The example here[1] doesn't
uses the destroy() statement at the end. Intuitional i would say that
the example is correct and that i don't need this statement. The
behaviour of the close button should be implemented already in the
close-button-handler of the Gtk.AboutDialog.

So is it a bug in the Fedora package that i need this statement or is it
a bug in the Debian, Ubuntu, Windows packages that it also works without
this statement?

[1] http://www.go-mono.com/docs/monodoc.ashx?tlink=5 at ecma%3a669%23AboutDialog%2f

best wishes,
Bjoern

The example doesn't have a Destroy call because the program ends immediately
after the Run call.  If you want the Dialog to go away on close, you should
either hide or destroy it when the Run call is done.  All Dialog subclasses
require this type of cleanup.

As far as why it works on fedora vs ubuntu, it's hard to provide any
reasonable response without knowing more details, like code, Gtk# versions,
Gtk+ versions, etc...

The short answer is, the Destroy () call is correct.

Subject: [Gtk-sharp-list] App using gecko-sharp won't start.
Message-ID: <fd3fe9230801250847w4f2d5475jb73ae93f4379c882@mail.gmail.com>

Hey Guys,

I am using the MonoDevelop IDE to build a GTK# application that embeds
Gecko. When run from within MD, the app starts up and works fine.
However, when I try to run it from the command line it won't work.

Running:

mono gecko-experiments.exe

ended with:

System.TypeInitializationException: An exception was thrown by the
type initializer for Gecko.WebControl --->
System.DllNotFoundException: /usr/lib/firefox/libgtkembedmoz.so

so I've set the LD_LIBRARY_PATH=/usr/lib/firefox and I got what can be
seen below. I tried enabling launch script generation in MD (0.14) but
I cannot see it generating any scripts. I'm running Ubuntu 7.10. Any
ideas on what's wrong with that?

Subject: [Gtk-sharp-list] .NET bindings for Tinymail,
	skeleton added to repository but I	still have some compilation
	problems
Message-ID: <1201476918.8677.80.camel@schtrumpf>

Hi there,

I just added the skeleton for .NET bindings to Tinymail.

Tinymail is a library intended for mobile E-mail clients.

The idea behind the library is to give infrastructure, tools and types
to build an E-mail client that'll run on a mobile device. It's core
goals are low memory consumption, few round trips and low bandwidth
requirements.

An example is Nokia's Modest which is using  Tinymail to create an
E-mail client for the N800 and N810 devices. 

bla bla bla

Its types are very often GTypeInterface ones. I learned from Mike's blog
that newer Gapi versions have some support for this build in.

Eager to test this stuff, I tried it and indeed I'm seeing the various
Gapi tools find my interfaces and create .NET equivalents.

This is the SVN commit for the skeleton, by the way:
  http://tinymail.org/trac/tinymail/changeset/3302
You enable it using --enable-dotnet-bindings

cd bindings/dotnet ; make

It wont compile yet, though. I got these errors:

pvanhoof at schtrumpf:~/repos/tinymail/trunk/bindings/dotnet$ 


I wonder what my options are. Can I override sufficient things to get
rid of these problems? Can I provide my own alternative code for the
properties and methods that are failing here?

And how? And if documented, where can I find this documentation?

Another question: can I change the type hierarchy of generated types? I
for example have a Tny.List and a Tny.Iterator that I sure would like to
adapt to make it implement the IList interface of .NET. I also have a
Tny.Stream that I think could use some System.IO.Stream magic here and
there.

I would prefer to have language bindings that are comparable to each
other in API. I'm adding J?rg Billeter in CC. J?rg coded on the Vala
bindings for Tinymail. Vala, the programming language, is being designed
after C#. Therefore I'm confident that the bindings can be made to look
the same.

I noticed the previous errors where created by the code generator not
coping with _func appended vfunc names in the class's structs.

I removed those from the API, now I get this list of errors (which looks
more sane to me, but still, I wonder how to fix all this).

Subject: [Gtk-sharp-list] Announcing the 2nd Preview Release for Gtk 2.12
	and Gnome 2.20	bindings
Message-ID: <1201560604.1444.337.camel@t61p.site>

We are announcing the second public preview release of bindings for the
Gnome 2.20 APIs.  This release includes gnome-sharp-2.19.91 and
gnome-desktop-sharp-2.19.1 to fix configuration and API stability issues
identified in the initial release.  The gtk-sharp package remains at
version 2.11.91 released last week.

Tarballs are available from ftp.gnome.org, and packages for Fedora8 and
OpenSUSE 10.3 are available at:

http://download.opensuse.org/repositories/home:/mkestner/

These releases are not API-stable yet, but are sufficiently mature to
begin testing against.  Anticipated API adjustments are expected to be
minimal at this point but might occur until we reach the stable 2.12.0
and 2.20.0 versions.

The gtk-sharp package contains bindings for glib, pango, atk, gdk, gtk,
and glade.  The API versions bound correspond to the versions shipped in
the GNOME 2.20 platform release set.

The gnome-sharp package binding set has changed with this release.
Remaining in gnome-sharp are art, gnomevfs, libgnome, libgnomeui,
libgnomeprint, libgnomeprintui, libpanelapplet, libgnomecanvas, and
gconf bindings.

The gnome-desktop-sharp package contains updated versions of the
gtkhtml, rsvg and vte bindings previously shipped in gnome-sharp, as
well as new bindings for libgnome-desktop, libnautilus-burn, and
libwnck.  We expect to add gtksourceview2 bindings as well prior to the
final release.  Bindings shipped in this package are not guaranteed to
be API stable since the underlying libraries are not guaranteed API
stable.  Attempts will be made to maintain compatibility where possible,
using policy assemblies.  When API compatibility is broken in underlying
libraries, the associated bindings will be parallel-installable with
prior versions.

Testing packages for openSUSE 10.3 and Fedora 8 can be found at:

http://download.opensuse.org/repositories/home:/mkestner/

Source tarballs are available from ftp.gnome.org.

We expect to move rapidly toward the 2.12 and 2.20 final release, with
possibly one more preview depending on the number of issues identified.
Issues can be reported to bugzilla.novell.com module gtk#.

I'll take a look at this tomorrow.  Thanks for trying it out.  Those both
look like simple keyword mangling issues.  They just need to be added to the
SymbolTable method that does the mangling.  You could file a bug for those
as well if you wanted.

ps. I'm trying things like this without success. Studying that fixup
code :)


<?xml version="1.0"?>
<metadata>
 <remove-node path="/api/namespace/object[@cname='TnyList']/method[@cname='foreach']" />
</metadata>

Okay, will do. Some of the compilation errors are about actual words
being used that generate to a C# construction that uses a C# keyword.

Might be hard to fix. Lucky I don't really need them, although having
access the the C developer's fast foreach implementation of the list
could become useful when implementing a IList with a IEnumeratable, etc.

I'm guessing that if I want to add an 'implements', I do something like
this to the metadata file:

  <add-node path="/api/namespace/object[@cname='TnyList']/implements/interface[@name='IList']" />

And then make a List.custom that implements all that IList needs (which
can be done with tny's list API).

Right? (it's a guess)

That method cname would probably be something like tny_list_foreach, or you
could do @name='Foreach'.   The error is most likely due to a parameter
named foreach, though, I'm guessing, which could be renamed to foreach_cb or
something like that to get around the current lack of generator mangling.

Yep.  You can take a look at Gtk.ListStore.  It has an IEnumerable
implementation.  I hacked up that metadata rule above from its rule.

Subject: [Gtk-sharp-list] Tinymail DotNet bindings update
Message-ID: <1201686956.8544.15.camel@schtrumpf>

Hi there,

I just committed the DotNet bindings for Tinymail. People who've been
watching Tinymail's trunk might have noticed that I this this yesterday
and the day before already.

Today I completely restructured it, though. I made it more or less the
same as how gtk-sharp itself is structured. This means that each
separate library has its own subdirectory and the Makefile.am includes a
toplevel Makefile.include.

I even copied that Makefile.include from gtk-sharp's toplevel directory
and adapted it (once Gapi is installed, it's not necessary to put the
runtime's executable in front of it, and I had to adjust a few minor
other things too)

You can find the bindings here:

https://svn.tinymail.org/svn/tinymail/trunk/bindings/dotnet/


They might not be 100% correct. I tried hard to get everything right
immediately but I'm guessing it's not right yet.

For example the libtinymail-platform-sharp for some reason only has
one .cs file in generated. That can't be right. Most of the types that
in the C API only have a constructor also didn't get a .cs file in the
generated directory. If I look at the generated API, a lot is missing.

I have no clue why the codegenerator of gapi is not generating code for
those types. They do seem to be in the -api.xml and .raw files and they
are not slashed in the .metadata files.

The libtinymail-camel-sharp things seem to crash gapi's code generator,
so this one is not in the SUBDIRS of bindings/dotnet/Makefile.am a.t.m.

I'm generating .pc files for the pkgconfig libdir, but they might not be
completely correct. I tried mimicking gtk-sharp's files but I might have
gotten something wrong. I don't know (haven't testing it yet).

The SNK file, the AssemblyInfo.cs file, are all things that I might have
gotten wrong too. I tried copying as much as possible from how gtk-sharp
does all this magic.

I have not yet made .custom files for Tny.List and Tny.Stream. The
reason is that both are GTypeInterface types (interfaces in .NET) and
that adding code in the .custom file only alters the interface. It wont
alter the Adaptor that Gapi generates. So I can't really influence these
interfaces a lot (I can't make them require implementing IList, for
example).

For Tny.Stream I might have to rename the original Tny.Stream to
something else in the .NET binding and make the .NET version of
Tny.Stream inherit from System.IO.Stream. This, is going to be quite
tricky to get it right, I think.

I can really use assistance from the gurus in this channel. Tinymail is
a relatively large library (in terms of API availability) with more
compilation options, possibilities, combinations and switches than Gtk+
has. That's because the project's focus is mobiles and each and every
mobile is typically different from each other mobile.


Anyway .. so here's the skeleton of the binding. All the unpleasant
crappy autotools work is done.

The tweaking of it is something I'm sure a .NET enthusiast is going to
like working on.

By adapting the INCLUDE_API to contain the -api.xml files of libraries
where this one depends on, the crash no longer happens.

So this seems to be related to the dependencies (I noticed this as I was
reading the "implements unknown GInterface TnyBlaBla")

By adjusting the INCLUDE_API to contain the -api.xml files of depending
libraries (in this case the libraries libtinymailui, libtinymailui-gtk
and libtinymail-camel) this seems to have improved.

*learn learning learn*

I'm not sure if I'm still missing types but it looks like the ones that
I expect are now indeed being generated. 

Also check the crash that I mentioned in that other post on gtksharp's
mailing list. This was related too.

Hi there,

If I look at the prefix of both gtk-sharp and tinymail's -sharp
installation, I noticed that gtk-sharp has .config files installed.

Tinymail's -sharp install directory doesn't have these .config files
installed. I'm not really immediately finding what in the build of
gtk-sharp is installing them (I kept the Makefile.include identical for
that part of the build Makefile code afaik).

I'm guessing these config files are necessary for the .dll->.so mapping?
Something like that is what they seem to contain as XML data. Obviously
I mimicked them as good as possible using gtk-sharp's code.

Also, what is this policy.$(API_VERSION).config file for by the way?

Thanks.  I added some null checks for this in the ClassBase recursive lookup
methods on revision 94388.

gacutil installs .dll.config files if they are present.  They support
different dll/so/dylib naming conventions across various platforms.  The
convention is to use win32 dll naming in the DllImport statements in the
generated code, so that assemblies work on the MS runtime on win32.  We use
dllmap entries in the .config file so that mono can map them to the
appropriate nomenclature on *nix and mac.

Policy assemblies are the backward compatibility mechanism on .Net.  A
program built against assembly version 2.4.0.0 requires that specific
assembly version be available at runtime.  One way to satisfy that
requirement is to install a policy.2.4 assembly which "links" to a newer
assembly version that provides all of the API exposed by 2.4.0.0.

This is weird. Ubuntu/Debian does strange stuff here; the dllmap
should only map dll names, not full paths.

I'm not certain, but I think that GtkMozEmbed may require you to set
MOZILLA_FIVE_HOME to your Firefox directory too. MonoDevelop certainly
does this, which would propagate to child apps (e.g. when you run your
app from within MD).

Subject: [Gtk-sharp-list] Alpha channel to widget
Message-ID: <1201804803.4405.0.camel@act1v8>

Hello,

I've been struggling with this for a week now, it is time to ask.

I need to create a Window, with a couple of widgets inside, one of which
is an EventBox (or any other paintable parent widget). That parent
window, the EventBox, contains it's child widgets, such as a Table and
some custom widgets. Now, what I need is to give the EventBox and the
table some transparency, with color of course something like, in RGBA:
1, 0, 0, 0.5... what we now would refer to Composited backround, but the
custom widgets to stay intact, that is they should not catch on the
alpha of the transparency. They should stay the way they are.

Over the last week I tried everything I can think of. And it always
proved wrong... either I saw no change, or I saw everything black or
everything fully transparent. I even got a transparent drawing over the
whole window. Once, when I tried compiling with gmcs, I couldn't create
a cairo context with the Gdk.CairoHelper thing.

I used Cairo and plain Gtk. Nothing worked. I am running Compiz Fusion,
of course.

Can you help?
