Message-ID: <1183318289.2332.4.camel@wasabi>

Hi. I've downloaded the sources of the Medsphere's installer of Gtk#
2.10.1, and I've modified them to support the .NET Framework 2.0.
Changes are very simple.

Here is the link to download:
http://code.google.com/p/zaspe-sharp/downloads/list

I hope it can be useful for someone else. Bye.

I wonder if you could take these changes to update the
gtk#, gtk+, and dependencies for Mono.

Does it include the gnome# and libgnome... too?

Cool!  I just have a few notes on your patch:

* Much of your Runtime.iss still references the v1.1 GAC, namely
  ConfigureGacInstallBat, and your SDK.iss is still set up for Visual
  C# 2003 (v7.1).  

* You still use both Medsphere's registry paths and our GUID.


Other than that, great work!

Cheers,

Sorry, but I have not enough time to do it soon.

No. I was using Gnome.DateEdit control in my app, but I had to replace
it with some controls of Gtk+. I thought it would take more time to
include gnome# in the installer than modifying my application to use
gtk-only controls to replace DateEdit.

Bye.

If I understood, that procedure (ConfigureGacInstallBat) checks if the
runtime or SDK are installed, and replace this string:

'C:\Program Files\Microsoft.NET\SDK\v1.1\'

by the real path of the SDK in both .bat files, which are used to add
and remove the gtk-sharp assemblies in the GAC. Is this right?

Some comments on this procedure are incorrect. For example, when it says
"// Base on SDK 1.1", while it's checking 2.0. I forgot to change it.

Regarding Visual Studio, I don't have version 2005 to test the
installer.

Thank you very much for your notes. I will try to fix them soon.

Message-ID: <20070705111050.C30317008B@herald.ximian.com>

Hi all,

I'm still having this problem where my main window loses focus after 
showing a dialog. The rather contrived scenario is one of the ways I 
can find to replicate the problem, which appears to occur as a result 
of launching one dialog from another dialog (for a context menu). 
Here I've demonstrated it occurring as a result of showing two dialogs at once.

It's not just that the window becomes inactive, Gtk# actively seeks 
out another application's window, brings it to the front, and 
activates it. This is making my application impossible to use. Please help!

Aaron.

Are you talking about gtk# on Windows?  If so, this is a well-known
problem that has been in GTK for a long time but will hopefully be fixed
very soon.  See: http://bugzilla.gnome.org/show_bug.cgi?id=112404

Check out Gdk.Display, which has static methods for getting instances of
Gdk.Screen class, which has the info you want.

Thanks very much for the link Cody. For anyone searching this list 
who, like me, doesn't normally search through the Gtk+ bugs as well, 
the link below contains a useable workaround.

About this Gtk# 2.10 for Windows, how long does it generally take for 
the Novell guys to get around to updating their installer packages? 
Gtk# 2.10 itself has already been around for ages, hasn't it?

Aaron.

Subject: [Gtk-sharp-list] Dumb question: Gtk# versions, Licensing
Message-ID: <20070714105854.2439670081@herald.ximian.com>

Hi all,

I'm having problems with users who seem to either have other versions 
of Gtk# or Gtk+ installed (under Windows), or for whom the installer 
from Novell is malfunctioning. As a result my app can't find its 
dependencies and won't run. This is generating one or two bug reports 
a week - about 10 times the usual traffic. :-)

I'm relatively new to open source development. I've always worked in 
environments where you buy the things you need and do whatever you 
like with them within the confines of the office. Hence, I see 
several options for Gtk# integration but I can't seem to find a solid 
statement about what is allowed and what is not. If anyone could add 
options or information to the list below or point me towards a 
readable source of info on this, I'd be very grateful.


My options seem to be (in order of best integration):

1 - Somehow add all of Gtk# and Gtk+ to my own project, compile them 
directly into it and put up with maintaining it (ie downloading and 
remodifying new versions as they are released by you guys). This 
would probably involve me having to get Gtk+ to compile as well 
(Linuxy C++, argh!), so I won't be doing this unless it turns out to 
be much easier than it sounds. On the bright side, it should be OK 
provided I ship all that source in my code releases.

2 - Rip all necessary DLLs from the Gtk# installer (that would 
include Gtk+ DLLs) from Novell and put them in my bin directory upon 
installation. This is the most attractive option, and should be the 
most reliable option. This would be a pretty flagrant violation of 
copyright (or something) though, wouldn't it?

3 - Compile my own DLLs using the Gtk# source code and put them in 
the installer. My understanding is that this would be allowed, 
provided the source for 'my' Gtk# DLLs was available with the rest of 
the code. For the same reasons as #1, this is not an attractive 
option. I could possibly rely on a Gtk+ installer but I think that's 
been part of the problem too, or at the very least has the potential 
to land me in exactly the same situation again later.

4 - Keep using Novell's installer, but integrated into mine. This has 
been giving me headaches but only with a few users. I just hate the 
fact that my software may be directly incompatible with other 
software (like Pidgin) because I'm using Gtk#. Installer integration 
would ensure that only users with broken installs had problems, but 
could actually break other people's software!


As you can see, I seem to be stuck between options that involve me 
appropriating and working with all of Gtk#'s source code, doing 
things I'm not sure are legal (let alone moral), or creating an 
installer that breaks other software. :-(

I apologise if everyone is reading this and thinking "well, duh", but 
as I said I'm new to this and try as I might I can't seem to find a 
clear statement about each of these alternatives or what the hell to 
do about it all, especially as a chump end user of Gtk# on Windows 
who can't compile it for himself. :-)

Thanks in advance for any (more) help you guys can give me,

Aaron.

Won't comment on the legal bits, but just pinpoint that GTK+ isn't
Linuxy C++, It's object-organized pure C code.

Subject: [Gtk-sharp-list] Implementing a tree model using the Gtk.Treemodel
	interface
Message-ID: <1184589490.19675.3.camel@jeroen-laptop>

Hello,

I want to implement my own treemodel and I inherited from the
Gtk.Treemodel interface. 
This doesn't seem to work though, none of the methods in my own model is
called.

Is implementing the Gtk.Treemodel the right way to go? Or should I
inherit from a baseclass? Or is inherting from the Gtk.Treemodel not
enough.

To answer my own question...

It seems that the only way to change the size is via the theme engine. See
http://ubuntuforums.org/showthread.php?t=255065. Haven't found anything 
about TreeView expanders, though.

here is my problem: I want to install monodevelop, and to do this I have
to install gtksourceview#.
But this last one does not recognize gnome#:

   checking for GTK_SHARP... configure: error: Package requirements
(gnome-sharp-2.0 >= 1.9.3) were not met:

   No package 'gnome-sharp-2.0' found

   Consider adjusting the PKG_CONFIG_PATH environment variable if you

   Alternatively, you may set the environment variables GTK_SHARP_CFLAGS
   and GTK_SHARP_LIBS to avoid the need to call pkg-config.
   See the pkg-config man page for more details.

so I reinstalled gnome-sharp and after having entered "./configure" I
have the following message:

   ---

  * Installation prefix = /opt/local
  * C# compiler: /opt/local/bin/mcs  -define:GTK_SHARP_2_6

so we can see that gnome-sharp is not installed.(what is confirmed if I
go to /opt/local/lib/pkgconfig, where there is no gnome-sharp-2.0.pc file).

Do you know how I can install this dll?Is there an option of the
"configure" command I didn't used?

Gnome# is a package on it's own.

http://anonsvn.mono-project.com/viewcvs/trunk/gnome-sharp/ is a web link
to it.
svn://anonsvn.mono-project.com/source/trunk/gnome-sharp is the SVN
checkout link.
If you are installing from a tarbal archive it should have been included
as well.

Also note that Gnome# contains gtkhtml. That might also be a requirement
and is a question that frequently pops-up.

Jensen

I would like to have gnome-sharp.dll installed.
I saw there exists some options of "configure": "--enable-FEATURE", and 
"--with-PACKAGE"; I think it could help me to install gnome-sharp.dll 
but I do not find which feature or which package to enter (I tried 
"--enable-gnome-sharp" e.g. but it does not works).

Hi!

I have made a simple Code Generator for C#. It is updating the GUI

checks through Reflection which kind of EventArgs a Signal is offering.
It is available at:

http://www.codeproject.com/csharp/GladeCodeChanger.asp

If you like it, and think that it is a help maybe you could make a 
reference in "starting with Gtk#" on the Mono Page. I would also offer 
to write an introduction. It is tested in .Net and Mono.

Also comments about wishes for functionality are welcome!

Hi Jensen,

you know, I'm a newbie in the world of linux,mac (and moreover a 
switcher) and maybe I have not understood as I should have, but when I 
enter "./configure --prefix=/opt/local" to install gnome-sharp, the 
process goes on until the end, but the file gnome-sharp.dll is not 
installed.

do you know how I can install it?


thank you,

As the above indicates, you need to install some devel packages.  The
most likely culprits for gnome-sharp are libgnomeprint, libgnomeprintui,
and gnome-panel.

Are there not any gnome-sharp packages available for your platform?

Hello mike,

thank you for your answer.
I will try to install these 3 packages, if I can find them. If I can 
not, do you think the regular package is good also?
And I did not found any package for gnome-sharp.

I will give you some news if something happens.

I wrote a little patch to address this problem.
This patch doesn't add gconf_schema_new and gconf_schema_set_* support,
but get_* should be sufficient for most use cases.

I guess I could implement the other functions if you consider them
useful.

cheers,
Mario

It would be good if the script was more specific about which devel
packages might be missing, specially for gnome-sharp. The requirement of
libgnomeprint* and gnome-panel are not obvious.

Yeah, nobody seems to know how to use config.log.

I added a blurb about the required libs.  Hopefully people will be able
to figure out which packages provide them.

What does this have to do with Gtk#?  Seems like a general mono question.

Anyway,  I believe Oo Base uses Hypersonic.  So if you can find a .NET provider for Hypersonic 
that should work.

It depends, if you want access to the interface look at the
Python-UNO[1] bridge in OOo, if you want access to the data itself there
may be a driver via odbc or a .NET provider for its Database engine[2].

Remember an OOo database is simply a zip file, unpack and access.

Subject: [Gtk-sharp-list] Gtk.TreeModelFilterModifyFunc NOT working -> Patch
Message-ID: <46AF6734.3030205@gmx.net>

Hi,

I have discovered a really serious bug in Gtk# appointing 
Gtk.TreeModelFilterModifyFunc.

As you probably know it is possible to set a modify function to a 
Gtk.TreeModelFilter to modify the display of the underlying 
Gtk.TreeModel. In fact that means nothing different than creating a 
different model based on the old one, but with different columns.

This can be very useful if you have a Gtk.TreeModel containing objects 
of a custom datatype. If you want to expose this model on a Gtk.TreeView 
you can either use a CellDataFunc to render the content of the TreeView 
or you can create a new TreeModel based on the old one with some columns 
containing data in a format that can be rendered by setting rendering 
attributes via AddAttribute(for example of type System.String). The 
second option can be done very easily and handy by using a ModifyFunc 
that is called for each data access/cell in the new model.

A code example:

void xyz()
{
   GLib.GType[] ColTypes = new GLib.GType[5];
   ColTypes[0] = GLib.GType.Int;
   ColTypes[1] = GLib.GType.String;
   ColTypes[2] = GLib.GType.String;
   ColTypes[3] = GLib.GType.String;
   ColTypes[4] = GLib.GType.String;
   treeview.SetModifyFunc(5, ColTypes, this.ModifyFunc);
}

private void ModifyFunc(Gtk.TreeModel model, Gtk.TreeIter iter, 
GLib.Value val, System.Int32 ColID)
{
   // Get corresponding iter(row) in the old model
   Gtk.TreeIter MainIter;
   TreeModel.GetIterFromString(out MainIter, 
model.GetPath(iter).ToString());
     // Fill the cell with the book's properties
   switch(ColID)
   {
       case 0:
           val.Val = (TreeModel.GetValue(MainIter, 0) as 
Bestandsverwaltung.Database.DataStruct.Book).ID;            break;
       case 1:
           val.Val = (TreeModel.GetValue(MainIter, 0) as 
Bestandsverwaltung.Database.DataStruct.Book).BookType.Title;
           break;
       case 2:
            val.Val = (TreeModel.GetValue(MainIter, 0) as 
Bestandsverwaltung.Database.DataStruct.Book).BookType.Publisher;
           break;
        case 3:
           val.Val = (TreeModel.GetValue(MainIter, 0) as 
Bestandsverwaltung.Database.DataStruct.Book).BookType.Faculty.Name;
           System.Console.WriteLine((System.String) val.Val);
           break;
       case 4:
           val.Val = (TreeModel.GetValue(MainIter, 0) as 
Bestandsverwaltung.Database.DataStruct.Book).DamageDescr;
           System.Console.WriteLine((System.String) val.Val);
           break;
   }
}

As you see it is necessary to modify the parameter named val as it 
contains the new content of the cell. *Therefore it needs to be passed 
by reference and NOT by value* because otherwise the parameter(e.g. the 
new content of this cell) cannot be modified. That means that the above 
code snippet won't work and the content of the cell will always stay 
uninitialized(or, to be correct, stay initialized with the default 
value, which is 0 for a numeric datatype, "" for GLib.GType.String and 
so on).

That's the reason why the ModifyFunc is not working. The delegate has to 
be changed so that the val argument is passed by reference.

To do so, I have downloaded the sources of Gtk version 2.10 and also 
made it to find and fix the error(and even a second one). It's hidden in 
GtkSharp.TreeModelFilterModifyFuncNative.cs and 
TreeModelFilterModifyFunc.cs in the /gtk/generated directory, which are 
autogenerated by GAPI. However, I cannot commit a patch for this error 
because I simply didn't have the time to get familiar enough with GAPI 
to find out how the files are generated. But I modified them, recompiled 
the assembly, installed it into the GAC via make install and finally 
really got it working!

These are the new versions of the files:
*

When you assign _arg2 to value(/GLib.Value _arg2 = value;/), normally 
both should be equal e.g. contain a reference to the same place in 
memory as they are no value datatypes like System.String. But to my own 
surprise this code didn't work. It is really necessary to pass the 
variable value directly to the delegate functionas in the complete 
listing further above.

model.GetPath(iter).ToString());
     // Fill the cell with the book's properties
   switch(ColID)
   {
       case 0:
           val.Val = (TreeModel.GetValue(MainIter, 0) as 
Bestandsverwaltung.Database.DataStruct.Book).ID;            break;
       case 1:
           val.Val = (TreeModel.GetValue(MainIter, 0) as 
Bestandsverwaltung.Database.DataStruct.Book).BookType.Title;
           break;
       case 2:
            val.Val = (TreeModel.GetValue(MainIter, 0) as 
Bestandsverwaltung.Database.DataStruct.Book).BookType.Publisher;
           break;
        case 3:
           val.Val = (TreeModel.GetValue(MainIter, 0) as 
Bestandsverwaltung.Database.DataStruct.Book).BookType.Faculty.Name;
           System.Console.WriteLine((System.String) val.Val);
           break;
       case 4:
           val.Val = (TreeModel.GetValue(MainIter, 0) as 
Bestandsverwaltung.Database.DataStruct.Book).DamageDescr;
           System.Console.WriteLine((System.String) val.Val);
           break;
   }
}

As you see it is necessary to modify the parameter named val as it 
contains the new content of the cell. *Therefore it needs to be passed 
by reference and NOT by value* because otherwise the parameter(e.g. the 
new content of this cell) cannot be modified. That means that the above 
code snippet won't work and the content of the cell will always stay 
uninitialized(or, to be correct, stay initialized with the default 
value, which is 0 for a numeric datatype, "" for GLib.GType.String and 
so on).

That's the reason why the ModifyFunc is not working. The delegate has to 
be changed so that the val argument is passed by reference.

To do so, I have downloaded the sources of Gtk version 2.10 and also 
made it to find and fix the error(and even a second one). It's hidden in 
GtkSharp.TreeModelFilterModifyFuncNative.cs and 
TreeModelFilterModifyFunc.cs in the /gtk/generated directory, which are 
autogenerated by GAPI. However, I cannot commit a patch for this error 
because I simply didn't have the time to get familiar enough with GAPI 
to find out how the files are generated. But I modified them, recompiled 
the assembly, installed it into the GAC via make install and finally 
really got it working!


These are the new versions of the files:

       {
           Gtk.TreeModel _arg0 = GLib.Object.GetObject(model) as 
Gtk.TreeModel;
           Gtk.TreeIter _arg1 = iter;
           int _arg3 = column;
           managed ( _arg0,  _arg1, ref value,  _arg3);
       }

       internal TreeModelFilterModifyFuncNative NativeDelegate;
       Gtk.TreeModelFilterModifyFunc managed;

       public TreeModelFilterModifyFuncWrapper 
(Gtk.TreeModelFilterModifyFunc managed)
       {
           this.managed = managed;
           if (managed != null)
               NativeDelegate = new TreeModelFilterModifyFuncNative 
(NativeCallback);
       }

       public static Gtk.TreeModelFilterModifyFunc GetManagedDelegate 
(TreeModelFilterModifyFuncNative native)
       {
           if (native == null)
               return null;
           TreeModelFilterModifyFuncWrapper wrapper = 
(TreeModelFilterModifyFuncWrapper) native.Target;
           if (wrapper == null)
               return null;
           return wrapper.managed;
       }
   }

*/*TreeModelFilterModifyFunc.cs:*

/// This file was generated by the Gtk# code generator.
// Any changes made will be lost if regenerated.

namespace Gtk {

   using System;

   public delegate void TreeModelFilterModifyFunc(Gtk.TreeModel model, 
Gtk.TreeIter iter, ref GLib.Value value, int column);

}

/Everything I did in the TreeModelFilterModyFunc.cs file was to change 
the delegate so that value is passed by reference. Therefore I also 
needed to change GtkSharp.TreeModelFilterModifyFuncNative.cs. But my 
first change wasn't enough because there is still another error hidden 
in the second file:

/public void NativeCallback (IntPtr model, ref Gtk.TreeIter iter, ref 
GLib.Value value, int column, IntPtr data)
{
   Gtk.TreeModel _arg0 = GLib.Object.GetObject(model) as Gtk.TreeModel;
   Gtk.TreeIter _arg1 = iter;
   GLib.Value _arg2 = value;
   int _arg3 = column;
   managed ( _arg0,  _arg1, ref _arg2,  _arg3);
}/

When you assign _arg2 to value(/GLib.Value _arg2 = value;/), normally 
both should be equal e.g. contain a reference to the same place in 
memory as they are no value datatypes like System.String. But to my own 
surprise this code didn't work. It is really necessary to pass the 
variable value directly to the delegate functionas in the complete 
listing further above.

After doing so, I have recompiled the assembly, modified my program and 
suddenly the ModifyFunc worked! I have attached the gtk-sharp.dll 
assembly based on Gtk 2.10 where these errors are corrected can be found 
here: http://www.gmx.de/mc/CEtA2LYY4TxOZNeZS9qDwVtFhPCp1E(after opening 
the link in your browser you have to click on "GMX Media Center starten" 
to see and download the file; I'm sorry for this, but the list doesn't 
seem to accept such large attachments). Of course, fixing this error 
with the modify func will break support for old programs using it. But I 
don't think there are any; there is nearly no documentation to be found 
on this function and when I searched for it I didn't find any example 
for Mono(quiet logical ^^). That's why I really ask you to get this 
fixed; If you want, I can also update the Mono documentation and post an 
example for the correct use of this function.

However, who added this non-working code to the repository didn't test 
it; otherwise the error would have been noticed because it occurs 
everytime when using this function. Quiet a worse indicator for the code 
quality in Gtk#.
