# Detail

Together with `Socket`, `Plug` provides the ability to embed widgets from one process into another process in a fashion that is transparent to the user. One process creates a `Socket` widget and, passes the ID of that widgets window to the other process, which then creates a `Plug` with that window ID. Any widgets contained in the `Plug` then will appear inside the first applications window.

# Constructors

plugNew

Arguments

:: Maybe NativeWindowId | `socketId` - the window ID of the socket, or `Nothing`.
-> IO Plug |

Creates a new plug widget inside the `Socket` identified by `socketId`. If `socketId` is `Nothing`, the plug is left "unplugged" and can later be plugged into a `Socket` by `socketAddId`.

If a NativeWindowId is supplied the foreign application window will immediatly appear in this `Plug` once it is shown. If `Nothing` is passed then a `NativeWindowId` can be extracted from this `Plug` using `plugGetId` and be passed to the application which is to be embedded.

plugNewForDisplay

Arguments

:: Display | `display` - the `Display` on which `socketId` is displayed
-> Maybe NativeWindowId | `socketId` - the XID of the socket's window.
-> IO Plug |

Create a new plug widget inside the `Socket` identified by socket_id.

- Available since Gtk+ version 2.2

# Methods

plugGetId

Arguments

:: PlugClass self |
=> self |
-> IO NativeWindowId | returns the window ID for the plug

Gets the window ID of a `Plug` widget, which can then be used to embed this window inside another window, for instance with `socketAddId`.

plugGetEmbedded

Arguments

:: PlugClass self |
=> self |
-> IO Bool | returns `True` if the plug is embedded in a socket

Determines whether the plug is embedded in a socket.

- Available since Gtk+ version 2.14

plugGetSocketWindow

Arguments

:: PlugClass self |
=> self |
-> IO (Maybe DrawWindow) | returns the window of the socket

Retrieves the socket the plug is embedded in.

- Available since Gtk+ version 2.14

# Attributes

plugAttrEmbedded :: PlugClass self => ReadAttr self Bool

`True` if the plug is embedded in a socket.

Default value: `False`

- Available since Gtk+ version 2.12

plugAttrSocketWindow :: PlugClass self => ReadAttr self (Maybe DrawWindow)

The window of the socket the plug is embedded in.

- Available since Gtk+ version 2.14

# Signals

plugEmbedded :: PlugClass self => Signal self (IO ())

Gets emitted when the plug becomes embedded in a socket and when the embedding ends.
