DCheckBox.OnChange() returns the panel?

[PC Camp]

I must be going blind or retarded.

Code:
[lua]
local comval = GetConVarNumber( com )
local box = vgui.Create( "DCheckBox", panel )
box:SetPos( 3, 0 )
box:SetChecked( comval )
box:SetValue( comval )
box.OnChange = function( valuz )
Msg( tostring(valuz).."\n\n" )
--ASA.Rcon( com, tostring(valuz) )
end
[/lua]

Console:

Panel: 23A8EE78

My console messages a panel object! Not a bool or a number. What the **** is happening? lol

[lua]box.OnChange = function( pnl, valuz )[/lua]

The source of the DCheckBox say's this:
[lua]
/*---------------------------------------------------------
Name: OnChange
---------------------------------------------------------*/
function PANEL:OnChange( bVal )

// For override

end
[/lua]

It's because of the difference between : and .

I don't really know how to explain it, but : is used when you want the first parameter to automatically be the upvalue (in this case the panel) of the function.

":" is syntactic sugar for ".bla(bla,...)"

ie

[lua]
function something:AFunc( a, b )

==

function something.AFunc( self, a, b )

and

something:AFunc( 1, 2 )

==

something.AFunc( something, 1, 2 )
