Description [src]
class Clutter.TextBuffer : GObject.Object
{
/* No available fields */
}
Text buffer for ClutterText
The ClutterTextBuffer
class contains the actual text displayed in a
ClutterText
widget.
A single ClutterTextBuffer
object can be shared by multiple ClutterText
widgets which will then share the same text content, but not the cursor
position, visibility attributes, icon etc.
ClutterTextBuffer
may be derived from. Such a derived class might allow
text to be stored in an alternate location, such as non-pageable memory,
useful in the case of important passwords. Or a derived class could
integrate with an application’s concept of undo/redo.

. If n_chars
is negative, then all characters
until the end of the text are deleted.
since: 13
clutter_text_buffer_emit_deleted_text
Emits the ClutterTextBuffer::deleted-text
signal on buffer
.
since: 13
clutter_text_buffer_emit_inserted_text
Emits the ClutterTextBuffer::inserted-text
signal on buffer
.
since: 13
clutter_text_buffer_get_bytes
Retrieves the length in bytes of the buffer.
See clutter_text_buffer_get_length()
.
since: 13
clutter_text_buffer_get_max_length
Retrieves the maximum allowed length of the text in
buffer
. See clutter_text_buffer_set_max_length()
.
since: 13
clutter_text_buffer_insert_text
Inserts n_chars
characters of chars
into the contents of the
buffer, at position position
.
