[Gtk-sharp-list] TestCombo from Ximian

[underdog10 at netcourrier.com]

Hello,

I still trying to set a event on a comboentry in order to received event.

it is crashing at
combo.Entry.Activated += new EventHandler (OnComboActivated);

This crash on both gtk version

I use this file as sample
http://svn.myrealbox.com/source/branches/gtk-sharp-1-0-branch/gtk-sharp/sample/test/TestCombo.cs


I just the main class to make it compile:

mcs TestCombo.cs -out:test.exe -pkg:gtk-sharp-2.0

mcs TestCombo.cs -out:test.exe -pkg:gtk-sharp

Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object
in <0x00189> WidgetViewer.TestCombo:Create ()
in <0x0000c> WidgetViewer.TestCombo:Main (System.String[] args)

Thanks,

/Francois
