## Member Function Documentation

void Gtk::TextBuffer::add_selection_clipboard | ( | const Glib::RefPtr<Clipboard>& | clipboard | ) |

  | Adds clipboard to the list of clipboards in which the selection contents of buffer are available. In most cases, clipboard will be the Gtk::Clipboard of type Gdk::SELECTION_PRIMARY for a view of buffer . Parameters:
  clipboard | A Gtk::Clipboard.

void Gtk::TextBuffer::apply_tag | ( | const Glib::RefPtr<Tag>& | tag,
|  | const iterator& | range_begin,
|  | const iterator& | range_end
| ) |

  | Emits the "apply_tag" signal on buffer . The default handler for the signal applies tag to the given range. start and end do not have to be in order. Parameters:
  tag | A Gtk::TextTag.
  start | One bound of range to be tagged.
  end | Other bound of range to be tagged.

void Gtk::TextBuffer::apply_tag_by_name | ( | const Glib::ustring& | name,
|  | const iterator& | range_begin,
|  | const iterator& | range_end
| ) |

  | Calls Gtk::TextTagTable::lookup() on the buffer's tag table to get a Gtk::TextTag, then calls apply_tag(). Parameters:
  name | Name of a named Gtk::TextTag.
  start | One bound of range to be tagged.
  end | Other bound of range to be tagged.

void Gtk::TextBuffer::assign | ( | const char* | text_begin,
|  | const char* | text_end
| ) |

| Alias for set_text().

void Gtk::TextBuffer::assign | ( | const Glib::ustring& | text | ) |

| Alias for set_text().

iterator Gtk::TextBuffer::begin | ( |  | ) |

void Gtk::TextBuffer::begin_user_action | ( |  | ) |

| Called to indicate that the buffer operations between here and a call to end_user_action() are part of a single user-visible operation. The operations between begin_user_action() and end_user_action() can then be grouped when creating an undo stack. Gtk::TextBuffer maintains a count of calls to begin_user_action() that have not been closed with a call to end_user_action(), and emits the "begin_user_action" and "end_user_action" signals only for the outermost pair of calls. This allows you to build user actions from other user actions. The "interactive" buffer mutation functions, such as insert_interactive(), automatically call begin/end user action around the buffer operations they perform, so there's no need to add extra calls if you user action consists solely of a single call to one of those functions.

void Gtk::TextBuffer::copy_clipboard | ( | const Glib::RefPtr<Clipboard>& | clipboard | ) |

  | Copies the currently-selected text to a clipboard. Parameters:
  clipboard | The Gtk::Clipboard object to copy to.

Glib::RefPtr<TextBuffer> Gtk::TextBuffer::create | ( | const Glib::RefPtr<TagTable>& | tag_table | ) | `[static]`

Glib::RefPtr<TextBuffer> Gtk::TextBuffer::create | ( |  | ) | `[static]`

Glib::RefPtr<TextChildAnchor> Gtk::TextBuffer::create_child_anchor | ( | const iterator& | pos | ) |

Glib::RefPtr<Mark> Gtk::TextBuffer::create_mark | ( | const iterator& | where,
|  | bool | left_gravity = true
| ) |

| Create an anonymous mark.

Glib::RefPtr<TextBuffer::Mark> Gtk::TextBuffer::create_mark | ( | const Glib::ustring& | mark_name,
|  | const iterator& | where,
|  | bool | left_gravity = true
| ) |

  | Creates a mark at position where . If mark_name is `0`, the mark is anonymous; otherwise, the mark can be retrieved by name using get_mark(). If a mark has left gravity, and text is inserted at the mark's current location, the mark will be moved to the left of the newly-inserted text. If the mark has right gravity ( left_gravity = `false`), the mark will end up on the right of newly-inserted text. The standard left-to-right cursor is a mark with right gravity (when you type, the cursor stays on the right side of the text you're typing). The caller of this function does not own a reference to the returned Gtk::TextMark, so you can ignore the return value if you like. Marks are owned by the buffer and go away when the buffer does. Emits the "mark_set" signal as notification of the mark's initial placement. Parameters:
  mark_name | Name for mark, or `0`.
  where | Location to place mark.
  left_gravity | Whether the mark has left gravity.
Returns: The new Gtk::TextMark object.

Glib::RefPtr<Tag> Gtk::TextBuffer::create_tag | ( | const Glib::ustring& | tag_name | ) |

void Gtk::TextBuffer::cut_clipboard | ( | const Glib::RefPtr<Clipboard>& | clipboard,
|  | bool | default_editable = true
| ) |

  | Copies the currently-selected text to a clipboard, then deletes said text if it's editable. Parameters:
  clipboard | The Gtk::Clipboard object to cut to.
  default_editable | Default editability of the buffer.

void Gtk::TextBuffer::delete_mark | ( | const Glib::RefPtr<Mark>& | mark | ) |

  | Deletes mark , so that it's no longer located anywhere in the buffer. Removes the reference the buffer holds to the mark, so if you don't keep a Glib::RefPtr to the mark, it will be freed. Even if the mark isn't freed, most operations on mark become invalid. There is no way to undelete a mark. Gtk::TextMark::get_deleted() will return `true` after this function has been called on a mark; Gtk::TextMark::get_deleted() indicates that a mark no longer belongs to a buffer. The "mark_deleted" signal will be emitted as notification after the mark is deleted. Parameters:
  mark | A Gtk::TextMark in buffer .

void Gtk::TextBuffer::delete_mark_by_name | ( | const Glib::ustring& | name | ) |

  | Deletes the mark named name ; the mark must exist. See delete_mark() for details. Parameters:
  name | Name of a mark in buffer .

iterator Gtk::TextBuffer::end | ( |  | ) |

void Gtk::TextBuffer::end_user_action | ( |  | ) |

| Should be paired with a call to begin_user_action(). See that function for a full explanation.

iterator Gtk::TextBuffer::erase | ( | const iterator& | range_begin,
|  | const iterator& | range_end
| ) |

| Returns the iterator where the deletion occured.

std::pair<iterator,bool> Gtk::TextBuffer::erase_interactive | ( | const iterator& | range_begin,
|  | const iterator& | range_end,
|  | bool | default_editable = true
| ) |

| Returns the iterator where the deletion occured or end() if no text was deleted.

bool Gtk::TextBuffer::erase_selection | ( | bool | interactive = true,
|  | bool | default_editable = true
| ) |

  | Deletes the range between the "insert" and "selection_bound" marks, that is, the currently-selected text. If interactive is `true`, the editability of the selection will be considered (users can't delete uneditable text). Parameters:
  interactive | Whether the deletion is caused by user interaction.
  default_editable | Whether the buffer is editable by default.
Returns: Whether there was a non-empty selection to delete.

void Gtk::TextBuffer::get_bounds | ( | iterator& | range_begin,
|  | iterator& | range_end
| ) |

int Gtk::TextBuffer::get_char_count | ( |  | ) |

| Gets the number of characters in the buffer; note that characters and bytes are not the same, you can't e.g. expect the contents of the buffer in string form to be this many bytes long. The character count is cached, so this function is very fast. Returns: Number of characters in the buffer.

Glib::RefPtr<TextBuffer::Mark> Gtk::TextBuffer::get_insert | ( |  | ) |

| Returns the mark that represents the cursor (insertion point). Equivalent to calling get_mark() to get the mark named "insert", but very slightly more efficient, and involves less typing. Returns: Insertion point mark.

iterator Gtk::TextBuffer::get_iter_at_child_anchor | ( | const Glib::RefPtr<TextChildAnchor>& | anchor | ) |

iterator Gtk::TextBuffer::get_iter_at_line | ( | int | line_number | ) |

iterator Gtk::TextBuffer::get_iter_at_line_index | ( | int | line_number,
|  | int | byte_index
| ) |

iterator Gtk::TextBuffer::get_iter_at_line_offset | ( | int | line_number,
|  | int | char_offset
| ) |

iterator Gtk::TextBuffer::get_iter_at_mark | ( | const Glib::RefPtr<Mark>& | mark | ) |

iterator Gtk::TextBuffer::get_iter_at_offset | ( | int | char_offset | ) |

int Gtk::TextBuffer::get_line_count | ( |  | ) |

| Obtains the number of lines in the buffer. This value is cached, so the function is very fast. Returns: Number of lines in the buffer.

Glib::RefPtr<const TextBuffer::Mark> Gtk::TextBuffer::get_mark | ( | const Glib::ustring& | name | ) | const

  | Returns the mark named name in buffer buffer , or `0` if no such mark exists in the buffer. Parameters:
  name | A mark name.
Returns: A Gtk::TextMark, or `0`.

Glib::RefPtr<TextBuffer::Mark> Gtk::TextBuffer::get_mark | ( | const Glib::ustring& | name | ) |

  | Returns the mark named name in buffer buffer , or `0` if no such mark exists in the buffer. Parameters:
  name | A mark name.
Returns: A Gtk::TextMark, or `0`.

bool Gtk::TextBuffer::get_modified | ( |  | ) |

| Indicates whether the buffer has been modified since the last call to set_modified() set the modification flag to `false`. Used for example to enable a "save" function in a text editor. Returns: `true` if the buffer has been modified.

Glib::RefPtr<TextBuffer::Mark> Gtk::TextBuffer::get_selection_bound | ( |  | ) |

| Returns the mark that represents the selection bound. Equivalent to calling get_mark() to get the mark named "selection_bound", but very slightly more efficient, and involves less typing. The currently-selected text in buffer is the region between the "selection_bound" and "insert" marks. If "selection_bound" and "insert" are in the same place, then there is no current selection. get_selection_bounds() is another convenient function for handling the selection, if you just want to know whether there's a selection and what its bounds are. Returns: Selection bound mark.

void Gtk::TextBuffer::get_selection_bounds | ( | iterator& | range_begin,
|  | iterator& | range_end
| ) |

Glib::ustring Gtk::TextBuffer::get_slice | ( | const iterator& | range_begin,
|  | const iterator& | range_end,
|  | bool | include_hidden_chars = true
| ) |

  | Returns the text in the range [ start , end ). Excludes undisplayed text (text marked with tags that set the invisibility attribute) if include_hidden_chars is `false`. The returned string includes a 0xFFFC character whenever the buffer contains embedded images, so byte and character indexes into the returned string do correspond to byte and character indexes into the buffer. Contrast with get_text(). Note that 0xFFFC can occur in normal text as well, so it is not a reliable indicator that a pixbuf or widget is in the buffer. Parameters:
  start | Start of a range.
  end | End of a range.
  include_hidden_chars | Whether to include invisible text.
Returns: An allocated UTF-8 string.

Glib::RefPtr<const TextBuffer::TagTable> Gtk::TextBuffer::get_tag_table | ( |  | ) |

| Get the Gtk::TextTagTable associated with this buffer. Returns: The buffer's tag table.

Glib::RefPtr<TextBuffer::TagTable> Gtk::TextBuffer::get_tag_table | ( |  | ) |

| Get the Gtk::TextTagTable associated with this buffer. Returns: The buffer's tag table.

Glib::ustring Gtk::TextBuffer::get_text | ( | bool | include_hidden_chars = true | ) |

Glib::ustring Gtk::TextBuffer::get_text | ( | const iterator& | range_begin,
|  | const iterator& | range_end,
|  | bool | include_hidden_chars = true
| ) |

  | Returns the text in the range [ start , end ). Excludes undisplayed text (text marked with tags that set the invisibility attribute) if include_hidden_chars is `false`. Does not include characters representing embedded images, so byte and character indexes into the returned string do not correspond to byte and character indexes into the buffer. Contrast with get_slice(). Parameters:
  start | Start of a range.
  end | End of a range.
  include_hidden_chars | Whether to include invisible text.
Returns: An allocated UTF-8 string.

void Gtk::TextBuffer::place_cursor | ( | const iterator& | where | ) |

  | This function moves the "insert" and "selection_bound" marks simultaneously. If you move them to the same place in two steps with move_mark(), you will temporarily select a region in between their old and new locations, which can be pretty inefficient since the temporarily-selected region will force stuff to be recalculated. This function moves them as a unit, which can be optimized. Parameters:
  where | Where to put the cursor.

void Gtk::TextBuffer::remove_all_tags | ( | const iterator& | range_begin,
|  | const iterator& | range_end
| ) |

  | Removes all tags in the range between start and end . Be careful with this function; it could remove tags added in code unrelated to the code you're currently writing. That is, using this function is probably a bad idea if you have two or more unrelated code sections that add tags. Parameters:
  start | One bound of range to be untagged.
  end | Other bound of range to be untagged.

void Gtk::TextBuffer::remove_selection_clipboard | ( | const Glib::RefPtr<Clipboard>& | clipboard | ) |

  | Removes a Gtk::Clipboard added with add_selection_clipboard(). Parameters:
  clipboard | A Gtk::Clipboard added to buffer by add_selection_clipboard().

void Gtk::TextBuffer::remove_tag | ( | const Glib::RefPtr<Tag>& | tag,
|  | const iterator& | range_begin,
|  | const iterator& | range_end
| ) |

  | Emits the "remove_tag" signal. The default handler for the signal removes all occurrences of tag from the given range. start and end don't have to be in order. Parameters:
  tag | A Gtk::TextTag.
  start | One bound of range to be untagged.
  end | Other bound of range to be untagged.

void Gtk::TextBuffer::remove_tag_by_name | ( | const Glib::ustring& | name,
|  | const iterator& | range_begin,
|  | const iterator& | range_end
| ) |

  | Calls Gtk::TextTagTable::lookup() on the buffer's tag table to get a Gtk::TextTag, then calls remove_tag(). Parameters:
  name | Name of a Gtk::TextTag.
  start | One bound of range to be untagged.
  end | Other bound of range to be untagged.

void Gtk::TextBuffer::set_modified | ( | bool | setting = true | ) |

  | Used to keep track of whether the buffer has been modified since the last time it was saved. Whenever the buffer is saved to disk, call gtk_text_buffer_set_modified ( buffer , `false`). When the buffer is modified, it will automatically toggled on the modified bit again. When the modified bit flips, the buffer emits a "modified_changed" signal. Parameters:
  setting | Modification flag setting.
