Re: [IronPython] Still stuck on rich editor with IronPython and Silverlight

Thanks very much - this is great news for us! I'm trying this now. Having to hardcode our AppManifest.xaml is unfortunate as we normally let Chiron generate this for us (whilst developing) - but I guess we could just recompile Chiron. 

Much appreciated,

Michael

AH! Thanks Dino!

In the XAP file there is an AppManifest.xaml, which specifies a version number. 
Ours (both what Chiron generates and what's on gestalt.ironpython.net) is still 
set to a version of SL2, for Moonlight compat, which turns on quirks mode when 
running in SL3+. Changing Chiron.exe.config's AppManifest template (or your own 
copy of AppManifest.xaml) to have SL4's version number will run without quirks 
mode enabled, hopefully letting you use the richtextbox.

For gestalt.ironpython.net, we will have multiple XAPs depending on what SL 
version you want to use, and the SL3 and 4 XAPs will have updates version 
numbers.

Michael, let me know how this works out for you.

Ok, I know what's going on here, but I don't know the exact solution.  I'm
hoping one of you two know the solution.  The good news is there's no bug,
the rich text box isn't supposed to work! :)

What's going on is that quirks mode is disabling the creation of the
rich text box.  This appears to be due to a version check against the
version that's coming from the XAP.  So I guess fixing some Silverlight '
version specified in the XAP file will fix this - I don't know if that's
a XAP being generated by Chiron or if it's something on gestalt.ironpython.net.

Michael, let's get Dino in on this ...

Dino, This seems like our fault, but I'm not savvy enough to track it

down or verify my claim. Seems like it doesn't work regardless of
invoking via reflection or ref.emit code; calling it's constructor
10,000 times still gave the same result. As Michael said, doing
anything with RichTextBox fails when invoked from IronPython, but works
fine when invoked without IronPython on the stack (pure C# app, for
example). I'm amazed that it fails when *called* from C#, meaning that
IronPython is doing something to make statically compiled code fail.

Thanks for looking at this Jimmy. IronPython must be doing something
really quite impressive here. :-)

All the best,

Michael


We can look at this together on Monday unless you get to it sooner; I

thought I knew how to use windbg but failed miserably at doing anything
useful, so you'll have to help :)

Hello all,

I'm still stuck on using the Silverlight 4 RichTextBox from

IronPython. Unfortunately this is blocking our project. :-(

Instantiating the RichTextBox directly or loading it from xaml

fails.

A wrapper class in C# that instantiates the RichTextBox and returns

it to IronPython fails.

A wrapper C# class that internally creates the RichTextBox but never

returns it to IronPython *still* fails. Anyone got any suggestions for
possible alternative approaches?

My latest (failing) attempt. C#:

  public static class Foo
  {
      static RichTextEditor _editor = null;

      public static void Create(StackPanel panel)
      {
          _editor = new RichTextEditor();
          panel.Children.Add(_editor);
      }
  }

IronPython:

clr.AddReference('SilverlightTextEditor, Version=1.0.0.0,

Culture=neutral')

canv = Canvas()
xaml = Application.Current.LoadRootVisual(canv, "app.xaml")

from SilverlightTextEditor import Foo
panel = StackPanel()
xaml.Children.Add(panel)

Foo.Create(panel)

(Note that RichTextEditor is a standalone UserControl editor

component built on top of the RichTextBox. It works fine from C#.)

All the best,

Michael Foord
