object

a GtkIMContext

This function is implemented by emitting the GtkIMContext::retrieve_surrounding signal on the input method; in response to this signal, a widget should provide as much context as is available, up to an entire paragraph, by calling gtkIMContextSetSurrounding. Note that there is no obligation for a widget to respond to the ::retrieve_surrounding signal, so input methods must be prepared to function without context.

A list containing the following elements:

`retval`	[logical] `TRUE` if surrounding text was provided; in this case you must free the result stored in *text.
`text`	location to store a UTF-8 encoded string of text holding context around the insertion point. If the function returns `TRUE`, then you must free the result stored in this location with `gFree()`.
`cursor.index`	location to store byte index of the insertion cursor within `text`.
