Declaration [src]
gboolean
gtk_im_context_get_surrounding_with_selection (
GtkIMContext* context,
char** text,
int* cursor_index,
int* anchor_index
)
Description [src]
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.
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
gtk_im_context_set_surrounding_with_selection().
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.
Available since: 4.2
Parameters
text-
Type:
char**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 g_free().The argument will be set by the function. The instance takes ownership of the data, and is responsible for freeing it. The value is a NUL terminated UTF-8 string. cursor_index-
Type:
int*Location to store byte index of the insertion cursor within
text.The argument will be set by the function. anchor_index-
Type:
int*Location to store byte index of the selection bound within
text.The argument will be set by the function.
