Plug

This feature is supported in wearable applications only.

The plug component shows an Evas_Object created by an other process. It can be used anywhere the same way as any other elementary UI component.

Adding a Plug Component

The following example shows how to create a plug.

Evas_Object *plug, *parent;
plug = elm_plug_add(parent);

Using the Plug

The socket image provides the service where to connect the plug object with the elm_plug_connect() function. In this process, use the service name and number set by the socket you want to connect to.

As an example, connect to a service named plug_test on the number 0.

elm_plug_connect(plug, "plug_test", 0, EINA_FALSE);

The Evas_Object corresponding to the distant image is retrieved with the elm_plug_image_object_get() function.

Evas_Object *plug_img = elm_plug_image_object_get(plug);

Note
The socket to connect to must be started with the elm_win_socket_listen() function in the other process on the remote window object (it is called remote_win here).

// Create a remote window in the other process 
Elm_Win *remote_win = elm_win_add(NULL, "Window Socket",
                                  ELM_WIN_SOCKET_IMAGE);
// Create a socket named "plug_test" and listen to it
elm_win_socket_listen(remote_win, "plug_test", 0, EINA_FALSE);
