[Gtk-sharp-list] ToolTips on a CellRendererToggle

[Moritz Angermann]

Hi Everybody...
Does anyone have an idea
how to add tooltips to a CellRendererToggle?

Lets say I have a column like:
	TreeViewColumn c = new TreeViewColumn( );
	c.Title = "Some Toggles";
	// First Toggle
	CellRendererToggle r = new CellRendererToggle( );
	r.Activatable = true;
	r.Toggled += new ToggledHandler( on_t1_toggled );
	c.PackStart( r, true );
	c.AddAttribute( r, "active", (int)myTree.TOGGLE1 );
	// Secound Toggle
	CellRendererToggle r = new CellRendererToggle( );
	r.Activatable = true;
	r.Toggled += new ToggledHandler( on_t2_toggled );
	c.PackStart( r, true );
	c.AddAttribute( r, "active", (int)myTree.TOGGLE2 );
	// ... [...] ...
	TreeView tv = new TreeView( );
	tv.AppendColumn( c );
	// ... [...] ...

Now I'd like to have a Tooltip when moving the mouse over the
toggle button.
ToolTips.SetTip( Widget, String, String ); requires a Widget
- so how do I get the ToggleButton Widget?

I'd appreciate help on this alot, thank you in advance,

kindest regards,
 -mo
