    [`GtkTextTagTable`]

### Convenient Construction

`gtkTextBuffer` is the equivalent of `gtkTextBufferNew`.

### User Functions

`GtkTextBufferDeserializeFunc(register.buffer, content.buffer, iter, data, length, create.tags, user.data, error)`

  A function that is called to deserialize rich text that has been serialized with `gtkTextBufferSerialize`, and insert it at `iter`.

  `register.buffer`

    the `GtkTextBuffer` the format is registered with

  `content.buffer`

    the `GtkTextBuffer` to deserialize into

  `iter`

    insertion point for the deserialized text

  `data`

    data to deserialize

  `length`

    length of `data`

  `create.tags`

    `TRUE` if deserializing may create tags

  `user.data`

    user data that was specified when registering the format

  `error`

    return location for a `GError`

  Returns: [logical] `TRUE` on success, `FALSE` otherwise

`GtkTextBufferSerializeFunc(register.buffer, content.buffer, start, end, length, user.data)`

  A function that is called to serialize the content of a text buffer. It must return the serialized form of the content.

  `register.buffer`

    the `GtkTextBuffer` for which the format is registered

  `content.buffer`

    the `GtkTextsBuffer` to serialize

  `start`

    start of the block of text to serialize

  `end`

    end of the block of text to serialize

  `length`

    Return location for the length of the serialized data

  `user.data`

    user data that was specified when registering the format

  Returns: [raw] a newly-allocated list of guint8 which contains the serialized data, or `NULL` if an error occurred

### Signals

`apply-tag(textbuffer, tag, start, end, user.data)`

  The ::apply-tag signal is emitted to apply a tag to a range of text in a `GtkTextBuffer`. Applying actually occurs in the default handler.

  Note that if your handler runs before the default handler it must not invalidate the `start` and `end` iters (or has to revalidate them).

  See also: `gtkTextBufferApplyTag`, `gtkTextBufferInsertWithTags`, `gtkTextBufferInsertRange`.

  `textbuffer`

    the object which received the signal

  `tag`

    the applied tag

  `start`

    the start of the range the tag is applied to

  `end`

    the end of the range the tag is applied to

  `user.data`

    user data set when the signal handler was connected.

`begin-user-action(textbuffer, user.data)`

  The ::begin-user-action signal is emitted at the beginning of a single user-visible operation on a `GtkTextBuffer`.

  See also: `gtkTextBufferBeginUserAction`, `gtkTextBufferInsertInteractive`, `gtkTextBufferInsertRangeInteractive`, `gtkTextBufferDeleteInteractive`, `gtkTextBufferBackspace`, `gtkTextBufferDeleteSelection`.

  `textbuffer`

    the object which received the signal

  `user.data`

    user data set when the signal handler was connected.

`changed(textbuffer, user.data)`

  The ::changed signal is emitted when the content of a `GtkTextBuffer` has changed.

  `textbuffer`

    the object which received the signal

  `user.data`

    user data set when the signal handler was connected.

`delete-range(textbuffer, start, end, user.data)`

  The ::delete-range signal is emitted to delete a range from a `GtkTextBuffer`.

  Note that if your handler runs before the default handler it must not invalidate the `start` and `end` iters (or has to revalidate them). The default signal handler revalidates the `start` and `end` iters to both point point to the location where text was deleted. Handlers which run after the default handler (see `gSignalConnectAfter()`) do not have access to the deleted text.

  See also: `gtkTextBufferDelete`.

  `textbuffer`

    the object which received the signal

  `start`

    the start of the range to be deleted

  `end`

    the end of the range to be deleted

  `user.data`

    user data set when the signal handler was connected.

`end-user-action(textbuffer, user.data)`

  The ::end-user-action signal is emitted at the end of a single user-visible operation on the `GtkTextBuffer`.

  See also: `gtkTextBufferEndUserAction`, `gtkTextBufferInsertInteractive`, `gtkTextBufferInsertRangeInteractive`, `gtkTextBufferDeleteInteractive`, `gtkTextBufferBackspace`, `gtkTextBufferDeleteSelection`, `gtkTextBufferBackspace`.

  `textbuffer`

    the object which received the signal

  `user.data`

    user data set when the signal handler was connected.

`insert-child-anchor(textbuffer, location, anchor, user.data)`

  The ::insert-child-anchor signal is emitted to insert a `GtkTextChildAnchor` in a `GtkTextBuffer`. Insertion actually occurs in the default handler.

  Note that if your handler runs before the default handler it must not invalidate the `location` iter (or has to revalidate it). The default signal handler revalidates it to be placed after the inserted `anchor`.

  See also: `gtkTextBufferInsertChildAnchor`.

  `textbuffer`

    the object which received the signal

  `location`

    position to insert `anchor` in `textbuffer`

  `anchor`

    the `GtkTextChildAnchor` to be inserted

  `user.data`

    user data set when the signal handler was connected.

`insert-pixbuf(textbuffer, location, pixbuf, user.data)`

  The ::insert-pixbuf signal is emitted to insert a `GdkPixbuf` in a `GtkTextBuffer`. Insertion actually occurs in the default handler.

  Note that if your handler runs before the default handler it must not invalidate the `location` iter (or has to revalidate it). The default signal handler revalidates it to be placed after the inserted `pixbuf`.

  See also: `gtkTextBufferInsertPixbuf`.

  `textbuffer`

    the object which received the signal

  `location`

    position to insert `pixbuf` in `textbuffer`

  `pixbuf`

    the `GdkPixbuf` to be inserted

  `user.data`

    user data set when the signal handler was connected.

`insert-text(textbuffer, location, text, len, user.data)`

  The ::insert-text signal is emitted to insert text in a `GtkTextBuffer`. Insertion actually occurs in the default handler.

  Note that if your handler runs before the default handler it must not invalidate the `location` iter (or has to revalidate it). The default signal handler revalidates it to point to the end of the inserted text.

  See also: `gtkTextBufferInsert`, `gtkTextBufferInsertRange`.

  `textbuffer`

    the object which received the signal

  `location`

    position to insert `text` in `textbuffer`

  `text`

    the UTF-8 text to be inserted

  `len`

    length of the inserted text in bytes

  `user.data`

    user data set when the signal handler was connected.

`mark-deleted(textbuffer, mark, user.data)`

  The ::mark-deleted signal is emitted as notification after a `GtkTextMark` is deleted.

  See also: `gtkTextBufferDeleteMark`.

  `textbuffer`

    the object which received the signal

  `mark`

    The mark that was deleted

  `user.data`

    user data set when the signal handler was connected.

    the object which received the signal

  `user.data`

    user data set when the signal handler was connected.

  `textbuffer`

    the object which received the signal

  `user.data`

    user data set when the signal handler was connected.

`remove-tag(textbuffer, tag, start, end, user.data)`

  The ::remove-tag signal is emitted to remove all occurrences of `tag` from a range of text in a `GtkTextBuffer`. Removal actually occurs in the default handler.

  Note that if your handler runs before the default handler it must not invalidate the `start` and `end` iters (or has to revalidate them).

  See also: `gtkTextBufferRemoveTag`.

  `textbuffer`

    the object which received the signal

  `tag`

    the tag to be removed

  `start`

    the start of the range the tag is removed from
