Declaration [src]

gtk_im_context_get_surrounding (
  GtkIMContext* context,
  char** text,
  int* cursor_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().

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.

Deprecated since: 4.2

Use gtk_im_context_get_surrounding_with_selection() instead.



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 caller of the method takes ownership of the returned data, and is responsible for freeing it.
The value is a NUL terminated UTF-8 string.

Type: int*

Location to store byte index of the insertion cursor within text.

The argument will be set by the function.

Return value

Type: gboolean

TRUE if surrounding text was provided; in this case you must free the result stored in text.
