I've written this script based on the snippets I found here on stackoverflow but get this error at runtime:
System.InvalidOperationException: Cannot create more than one System.Windows.Application instance in the same AppDomain.
I know it's got something to do with the fact that the last statement is creating a new Application instance within the same AppDomain but I don't know how to fix this. Here is the script:
clr.AddReference('PresentationCore')
clr.AddReference("PresentationFramework")
clr.AddReference('Microsoft.Dynamic')
clr.AddReference('Microsoft.Scripting')
clr.AddReference('System')
clr.AddReference('IronPython')
clr.AddReference('IronPython.Modules')
clr.AddReference('IronPython.Wpf')
from System.Windows import Application, Window
from IronPython.Modules import Wpf as wpf
class AboutWindow(Window):
def __init__(selfAbout):
wpf.LoadComponent( selfAbout, os.path.join( folder, 'AboutWindow.xaml' ))
class MyWindow(Window):
def __init__(self):
wpf.LoadComponent( self, os.path.join( folder, 'IronPythonWPF.xaml' ))
def MenuItem_Click(self, sender, e):
form = AboutWindow()
form.ShowDialog()
if __name__ == '__main__':
Application().Run( MyWindow() )
This seems to be the solution but don't know what parts of this code I would need to fix mine.
Here is the contents for the two XAML files:
__WIP__wpfTest__AboutWindow.xaml
<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="AboutWindow" Height="300" Width="300">
<Grid>
<TextBlock Text="AboutWindow" />
</Grid>
</Window>
__WIP__wpfTest__IronPythonWPF.xaml
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="IronPythonWPF" Height="300" Width="300">
<StackPanel>
<Menu>
<MenuItem Header="About" Click="MenuItem_Click" />
</Menu>
<TextBlock Text="MainWindow" />
</StackPanel>
</Window>
According to msdn, you should be able to use Window.Show (for a modeless version) or Window.ShowDialog (if you want to stay in the Revit API context)
The Application().Run( MyWindow() )
line basically sets up an event loop - something Revit already did for you at startup, so you can just go ahead and show your windows :)
I can't really test this solution since I don't have AboutWindow.xaml
and IronPythonWPF.xaml
, so I'm just guessing here... Have a go and tell me how it went.
