### Interface

# GtkSource HoverProvider

#### Description [src]

    interface GtkSource.HoverProvider : GObject.Object

Interface to populate interactive tooltips.

`GtkSourceHoverProvider` is an interface that should be implemented to extend the contents of a `GtkSourceHoverDisplay`. This is typical in editors that interact external tooling such as those utilizing Language Server Protocol.

If you can populate the `GtkSourceHoverDisplay` synchronously, use `GtkSource.HoverProviderInterface.populate`. Otherwise, interface implementations that may take additional time should use `GtkSource.HoverProviderInterface.populate_async` to avoid blocking the main loop.

#### Prerequisite

In order to implement HoverProvider, your type must inherit from`GObject`.
