## 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_overlay()

void Gtk::TextView::add_overlay | ( | Widget & | child,
|  | int | xpos,
|  | int | ypos
| ) |  |

Adds child at a fixed coordinate in the `Gtk::TextView`'s text window.

The xpos and ypos must be in buffer coordinates (see get_iter_location() to convert to buffer coordinates).

child will scroll with the text view.

If instead you want a widget that will not move with the `Gtk::TextView` contents see `Gtk::Overlay`.

Parameters

  child | A `Gtk::Widget`.
  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,

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.

Determine the positions of the strong and weak cursors if the insertion point is at iter.

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.

Returns
  `true` if the mark moved (wasn’t already onscreen).

## ◆ move_overlay()

void Gtk::TextView::move_overlay | ( | Widget & | child,
|  | int | xpos,
|  | int | ypos
| ) |  |

Updates the position of a child.

See add_overlay().

Parameters

  child | A widget already added with add_overlay().

## ◆ move_visually()

bool Gtk::TextView::move_visually | ( | TextBuffer::iterator & | iter,
|  | int | count
| ) |  |

Move the iterator a given number of characters visually, treating it as the strong cursor position.

If count is positive, then the new strong cursor position will be count positions to the right of the old cursor position. If count is negative then the new strong cursor position will be count positions to the left of the old cursor position.

In the presence of bi-directional text, the correspondence between logical and visual order will depend on the direction of the current run, and there may be jumps when the cursor is moved off of the end of a run.

Parameters

  iter | A `Gtk::TextIter`.
  count | Number of characters to move (negative moves left, positive moves right).

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

To avoid oddness, consider using gtk_text_view_scroll_to_mark() which saves a point to be scrolled to after line validation.

Parameters

  iter | An iterator pointing to the position that should be made visible by scrolling.
  within_margin | margin as a [0.0,0.5] fraction of screen size.
  xalign | horizontal alignment of mark within visible area. An alignment of 0.0 indicates left, 1.0 indicates right, 0.5 means center.
