Subject: [Python.NET] binding python objects to treenodes
Message-ID: <43242534.5050405@r-e-d.co.nz>

Hello,

Is there a way to bind a python object to a treeView node? I have the following 
treenode based class:

class dataNode(WinForms.TreeNode):

     def __init__(self,name,total):
         self.Text = name
         self.Total = total

And I add the node as such:

self.treeView1.Nodes.Add(dataNode("testnode",3))

But when I try and access the attributes it doesn't work?

    for node in self.treeView1.Nodes:
       print node.Total

Or should I keep the nodes in a list and access by index?

Any help appeciated.

Guy

Subject: [Python.NET] winForms, threading and dragdrop ?
Message-ID: <4324F84F.5040709@r-e-d.co.nz>

 From the attached code.With AllowDrop = True I get a .NET error as follows:

System.InvalidOperationException: DragDrop registration failed. ---> 
System.Threading.ThreadStateException: The current thread must set to Single 
Thread Apartment (STA) mode before OLE calls can be made.  Ensure that your Main 
function has STAThreadAttribute marked on it.

 From googling I need to set ApartmentState.STA. But this is readonly. How do I 
set STA correctly in Python for .NET?

Any thoughts appeciated.

Hi Guy -- as far as I know, you can't change the thread 
state after any COM or interop calls have happened (and 
Python for .NET is all interop...).

What you probably need to do is set the attribute in 
the C# 'embedding' application before initializing the 
python engine (or making any other interp calls).

Cheers Brian. Interestingly the script runs OK from within PythonWin. I guess 
PythonWin must be setting STA correctly but the python console doesn't?

Anyone else out there started to mess with Python.NET on the 2.0 platform? 
One of the first hurtles was the output from ildasm does not always place

1. i've tried and like active state's visual python. then i heard of this iron python beta thats fast and integrated w/ .NET.  I downloaded but don't know how to get it to work inside the .NET IDE. ???

Replace ReadMethod with the following:

    public void ReadMethod(string line)
    {
        Regex findMethod = new
Regex(@"^(\s*.method\s.*\s)([^\s()]+\([^()]*(?:,|\)\s.*))$");

        ArrayList lines = new ArrayList();
        string mline = line;

        string data;
        string buff;

        while ((data = reader.ReadLine()) != null)
        {
            buff = data.Trim();
            if (buff.StartsWith(ccAttr))
            {
                // BUG: mline may have method name in it already which breaks
                //      things.  This is mostly seen in .NET 2.0.
                // Example:  .method public hidebysig static int32 
tp_descr_set(native int ds,
                if (findMethod.IsMatch(mline))
                {
                    // method name is on same line as .method.  Need to insert
                    // modOpt prior to method name.
                    Match match = findMethod.Match(mline);

                    writer.WriteLine(match.Groups[1].Value + " ");
                    writer.WriteLine(modOpt + " ");
                    writer.WriteLine(match.Groups[2].Value);
                }
                else
                {
                    writer.WriteLine(mline);
                    writer.WriteLine(modOpt);
                }

                WriteBuffer(lines);
                writer.WriteLine(data);
                return;
            }
            else if (buff.StartsWith("} // end of method"))
            {
                writer.WriteLine(mline);
                WriteBuffer(lines);
                writer.WriteLine(data);
                return;
            }
            lines.Add(data);
        }

Thanks for the patch! I've been slammed lately and haven't 
had time to wrap up 1.0 and make the 2.x branch ;(

Any details you can post on the access violations would be 
helpful too (to me, anyway).

Here's something I just discovered.  You can now (in .NET 2.0) apply
the UnmanagedFunctionPointer attribute to delegate types to get them to
work as cdecl.  For example:

[UnmanagedFunctionPointer(CallingConvention.Cdecl)]
public delegate IntPtr UnaryFunc(IntPtr ob);

>From what I can tell, that delegate type is compatible with any managed
method with the right signature.  When called from unmanaged code, such
delegates will use the cdecl convention (this must be done in some kind
of thunk, since the method itself still uses the normal .NET calling
convention).

Anyway, the upshot is it looks like you can apply that attribute to all
the CallConvCDecl delegates in Interop.cs (removing the CallConvCDecl
attribute, since it's not needed), and then not need callconvutil at
all.

Message-ID: <FADE8AC60667634393734D8398A9F848027D8820@svlxchcln6.enterprise.veritas.com>

Is there any way to use PythonNet with the 2.0 version of the .Net
framework?  The assemblies we're working with will for the test harness
we're creating will all be .Net 2.0 assemblies, so if there's anything
we can do to get PythonNet working with them I'd be all ears.  I did
note that this will be a specific feature (as outlined by Brian) for the
PythonNet 2.x releases, but that appears to be a little way off...

 

Thanks in advance for you time.

Aaron
