I ran into several problems running the first Avalon example from the tutorial, using IP 0.9.6
I should mention that at this time I was running .net Framework 2.0 and the Dec 2005 CTP preview of WPF x64 versions without the Framework SDK; installing the SDK subsequently did not change the behaviour. I noticed three problems: - I couldn't set the Text attribute on a Window object - I couldn't set the TextContent attribute on a TextBlock object - the class RepeatBehaviour seems not to be imported. Another strange aspect is that I get this far when I enter the script interactively to the console, but when I put the script in a file and execute it from the command line I get the exception: "System.InvalidOperationException: The calling thread must be STA, as many UI components require this." on calling the Show method of the Window object. I think I might need to rebuild the console to sort this out - C# and .net threading models are rather a steep learning curve for this evening, so I've stuck to interactive experiments for now. Here's my console experience following the tutorial: G:\downloads\ironpython\IronPython-0.9.6\IronPython-0.9.6\Tutorial>ironpytho nconsole IronPython 0.9.6 on .NET 2.0.50727.42 Copyright (c) Microsoft Corporation. All rights reserved. >>> from avalon import * >>> w=Window () >>> w.Show () >>> w.Text="Avalon app" Traceback (most recent call last): at <shell> TypeError: can't set arbitrary attributes on built-in type System.Windows.Window This is quite right, because Windows do not have a Text attribute. However, if you set Title, all is well. >>> w.Content = TextBlock () >>> w.Content.TextContent = "Hello IronPython!" Traceback (most recent call last): at <shell> TypeError: can't set arbitrary attributes on built-in type System.Windows.Contro ls.TextBlock Similarly, w.Content.Text = "Hello IronPython", works just fine. You can discover the attributes of w of course just by: for (key, value) in w.__dict__.items (): print key, value (Iron)Python is so cool like that. >>> w.Content.FontSize = 50 >>> a=DoubleAnimation(0.0,Duration(TimeSpan.FromSeconds(3))) >>> a.RepeatBehaviour = RepeatBehaviour.Forever Traceback (most recent call last): at <shell> NameError: name 'RepeatBehaviour' is not defined >>> ^Z I didn't persist beyond here just yet. I suppose there have been some substantial changes in object properties during the evolution of WPF as seen in this latest preview, not yet reflected in the tutorial source - a life on the bleeding edge thing. >>> import sys >>> sys.path ['G:\\downloads\\ironpython\\IronPython-0.9.6\\IronPython-0.9.6\\Tutorial', 'G:\\downloads\\ironpython\\IronPython-0.9.6\\IronPython-0.9.6\\bin\\Lib'] >>> Anyway, a whole lot of wonderful things are working straight out of the box, including the XAML calculator. This is going to be a lot of fun. Thanks to everyone for getting things this far. Am I doing something silly to get the threading problem?
