InvisibleProtocol
public protocol InvisibleProtocol : WidgetProtocol
The GtkInvisible
widget is used internally in GTK+, and is probably not
very useful for application developers.
It is used for reliable pointer grabs and selection handling in the code for drag-and-drop.
The InvisibleProtocol
protocol exposes the methods and properties of an underlying GtkInvisible
instance.
The default implementation of these can be found in the protocol extension below.
For a concrete class that implements these methods and properties, see Invisible
.
Alternatively, use InvisibleRef
as a lighweight, unowned
reference if you already have an instance you just want to use.
