When creating menu and adding handlers to its event, MD creates twice the handler function...
Comment 1 Miguel de Icaza [MSFT] 2012-05-19 00:40:58 UTC

What kind of menu were you creating, for what kind of solution?

Gtk# solutions, Android solutions, other?

Hi Miguel,

I'm talking about a Gtk# (2.12) project.

I added two images two show it...
1.png is how it looks like from the Gtk# designer, and 2.png that shows the code generated after double-click on signal name...

Just got back to play around with Xamarin Studio and in version 5.7.1 with GTK# 2.12.26, the error still here...
