## Detailed Description

Multi-line text editing widget.

It displays a Gtk::TextBuffer.

The TextView widget looks like this:

## Constructor & Destructor Documentation

## ◆ TextView() [1/4]

Gtk::TextView::TextView | ( | TextView&& | src | ) |
| noexcept

## ◆ TextView() [2/4]

Gtk::TextView::TextView | ( | const TextView& |  | ) |
| delete

## ◆ ~TextView()

Gtk::TextView::~TextView | ( |  | ) |
| override noexcept

## ◆ TextView() [3/4]

Gtk::TextView::TextView | ( |  | ) |

## ◆ TextView() [4/4]

Gtk::TextView::TextView | ( | const Glib::RefPtr< TextBuffer >& | buffer | ) |

## Member Function Documentation

## ◆ add_child_at_anchor()

void Gtk::TextView::add_child_at_anchor | ( | Widget& | child,
|  | const Glib::RefPtr< TextBuffer::ChildAnchor >& | anchor
| ) |  |

Adds a child widget in the text buffer, at the given anchor.

Parameters

  child | A Gtk::Widget.
  anchor | A Gtk::TextChildAnchor in the Gtk::TextBuffer for text_view.

## ◆ add_child_in_window()

void Gtk::TextView::add_child_in_window | ( | Widget& | child,
|  | TextWindowType | which_window,
|  | int | xpos,
|  | int | ypos
| ) |  |

Adds a child at fixed coordinates in one of the text widget's windows.

The window must have nonzero size (see set_border_window_size()). Note that the child coordinates are given relative to scrolling. When placing a child in Gtk::TEXT_WINDOW_WIDGET, scrolling is irrelevant, the child floats above all scrollable areas. But when placing a child in one of the scrollable windows (border windows or text window) it will move with the scrolling as needed.

Parameters

  child | A Gtk::Widget.
  which_window | Which window the child should appear in.
  xpos | X position of child in window coordinates.
  ypos | Y position of child in window coordinates.

## ◆ backward_display_line()

bool Gtk::TextView::backward_display_line | ( | TextBuffer::iterator& | iter | ) |

Moves the given iter backward by one display (wrapped) line.

A display line is different from a paragraph. Paragraphs are separated by newlines or other paragraph separator characters. Display lines are created by line-wrapping a paragraph. If wrapping is turned off, display lines and paragraphs will be the same. Display lines are divided differently for each view, since they depend on the view’s width; paragraphs are the same in all views, since they depend on the contents of the Gtk::TextBuffer.

Parameters

  iter | A Gtk::TextIter.

Returns
  `true` if iter was moved and is not on the end iterator.

## ◆ backward_display_line_start()

bool Gtk::TextView::backward_display_line_start | ( | TextBuffer::iterator& | iter | ) |

Moves the given iter backward to the next display line start.

A display line is different from a paragraph. Paragraphs are separated by newlines or other paragraph separator characters. Display lines are created by line-wrapping a paragraph. If wrapping is turned off, display lines and paragraphs will be the same. Display lines are divided differently for each view, since they depend on the view’s width; paragraphs are the same in all views, since they depend on the contents of the Gtk::TextBuffer.

Parameters

  iter | A Gtk::TextIter.

Returns
  `true` if iter was moved and is not on the end iterator.

## ◆ buffer_to_window_coords()

void Gtk::TextView::buffer_to_window_coords | ( | TextWindowType | win,
|  | int | buffer_x,
|  | int | buffer_y,
|  | int & | window_x,
|  | int & | window_y
| ) |  | const

Converts coordinate ( buffer_x, buffer_y) to coordinates for the window win, and stores the result in ( window_x, window_y).

Note that you can’t convert coordinates for a nonexisting window (see set_border_window_size()).

Parameters

  win | A Gtk::TextWindowType except Gtk::TEXT_WINDOW_PRIVATE.
  buffer_x | Buffer x coordinate.
  buffer_y | Buffer y coordinate.
  window_x | Window x coordinate return location or `nullptr`.
  window_y | Window y coordinate return location or `nullptr`.

## ◆ forward_display_line()

bool Gtk::TextView::forward_display_line | ( | TextBuffer::iterator& | iter | ) |

Moves the given iter forward by one display (wrapped) line.

A display line is different from a paragraph. Paragraphs are separated by newlines or other paragraph separator characters. Display lines are created by line-wrapping a paragraph. If wrapping is turned off, display lines and paragraphs will be the same. Display lines are divided differently for each view, since they depend on the view’s width; paragraphs are the same in all views, since they depend on the contents of the Gtk::TextBuffer.

Parameters

  iter | A Gtk::TextIter.

Returns
  `true` if iter was moved and is not on the end iterator.

## ◆ forward_display_line_end()

bool Gtk::TextView::forward_display_line_end | ( | TextBuffer::iterator& | iter | ) |

Moves the given iter forward to the next display line end.

A display line is different from a paragraph. Paragraphs are separated by newlines or other paragraph separator characters. Display lines are created by line-wrapping a paragraph. If wrapping is turned off, display lines and paragraphs will be the same. Display lines are divided differently for each view, since they depend on the view’s width; paragraphs are the same in all views, since they depend on the contents of the Gtk::TextBuffer.

Parameters

  iter | A Gtk::TextIter.

Returns
  `true` if iter was moved and is not on the end iterator.

## ◆ get_accepts_tab()

bool Gtk::TextView::get_accepts_tab | ( |  | ) | const

Returns whether pressing the Tab key inserts a tab characters.

set_accepts_tab().

Since gtkmm 2.4:

Returns
  `true` if pressing the Tab key inserts a tab character, `false` if pressing the Tab key moves the keyboard focus.

## ◆ get_border_window_size()

Returns
  A Gtk::TextBuffer.

## ◆ get_buffer() [2/2]

Glib::RefPtr<const TextBuffer> Gtk::TextView::get_buffer | ( |  | ) | const

## ◆ get_cursor_locations()

void Gtk::TextView::get_cursor_locations | ( | const TextBuffer::iterator& | iter,
|  | Gdk::Rectangle& | strong,
|  | Gdk::Rectangle& | weak
| ) |  | const

Given an iter within a text layout, determine the positions of the strong and weak cursors if the insertion point is at that iterator.

The position of each cursor is stored as a zero-width rectangle. The strong cursor location is the location where characters of the directionality equal to the base direction of the paragraph are inserted. The weak cursor location is the location where characters of the directionality opposite to the base direction of the paragraph are inserted.

If iter is `nullptr`, the actual cursor position is used.

Note that if iter happens to be the actual cursor position, and there is currently an IM preedit sequence being entered, the returned locations will be adjusted to account for the preedit cursor’s offset within the preedit sequence.

The rectangle position is in buffer coordinates; use buffer_to_window_coords() to convert these coordinates to coordinates for one of the windows in the text view.

Since gtkmm 3.0:

Returns
  A new Gtk::TextAttributes.

## ◆ get_editable()

bool Gtk::TextView::get_editable | ( |  | ) | const

Returns the default editability of the Gtk::TextView.
