I've been trying to make a simple IronPython+Gtk# app that draws an
image to the screen, and I'm having trouble getting it to run in windows
(.NET). It's pretty simple so I attached it at the end.
It runs fine in Mono on Ubuntu and Windows, but when I try to run it on
windows using .NET I get the following error followed by a really long
calltrace:
Marshaling expose_event signal
Exception in Gtk# callback delegate
Note: Applications can use GLib.ExceptionManager.UnhandledException to
handle
the exception.
System.Reflection.TargetInvocationException: Exception has been thrown
by the ta
rget of an invocation. ---> System.NotSupportedException: The invoked
member is
not supported in a dynamic assembly.
at System.Reflection.Emit.AssemblyBuilder.get_Location()
at GLib.GType.LookupType(IntPtr typeid)
at ...
I have the latest 'Gtk# for .NET' package from the Mono site, and I've
tried with IP 2.0.1 and IP 2.6 Beta, they give the same results.
I rewrote the program in C# and it works fine in .NET (without Mono),
using #Develop IDE.
Is this possible?
code:
import clr
clr.AddReference('gtk-sharp')
clr.AddReference('gdk-sharp')
import Gtk
import Gdk
class MyWindow(Gtk.Window):
def __init__(self, title='Main Window'):
Gtk.Window.__init__(self, title)
self.pb = Gdk.Pixbuf('image.jpg').ScaleSimple(600,436,
Gdk.InterpType.Bilinear )
self.da = Gtk.DrawingArea()
self.da.SetSizeRequest(self.pb.Width, self.pb.Height)
self.Add(self.da)
self.Decorated = False
self.DeleteEvent += self.delete_event
self.da.ExposeEvent += self.expose_event
def expose_event(self, *args):
self.da.GdkWindow.DrawPixbuf(
self.Style.BackgroundGC(self.State), self.pb, 0, 0, 0, 0,-1, -1,
Gdk.RgbDither.None, 0, 0)
def delete_event(self, *args):
Gtk.Application.Quit()
if __name__ in ['__main__','Program']:
Gtk.Application.Init()
mw = MyWindow('Test')
mw.ShowAll()
Gtk.Application.Run()
