[Gtk-sharp-list] Inserting Pixbufs into a TreeView?

[Charles-Louis]

Solved the problem... the initialization of my TreeStore was incorrect.

By adding 

new TreeStore	((int)TypeFundamentals.TypeString,
		(int)TypeFundamentals.TypeString,		 
		(int)TypeFundamentals.TypeObject)
		
		--> Object was required for pixbuf
It worked...
