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
