gtkIMContextGetSurrounding
Retrieves context around the insertion point. Input methods typically want context in order to constrain input text based on existing text; this is important for languages such as Thai where only some sequences of characters are allowed.
gtkIMContextGetSurrounding(object)
|
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:

[logical] |

location to store a UTF-8 encoded string of text
holding context around the insertion point.
If the function returns |

location to store byte index of the insertion cursor
