## Detailed Description

Multi-line text editing widget.

It displays a Gtk::TextBuffer.

The TextView widget looks like this:

## Constructor & Destructor Documentation

virtual Gtk::TextView::~TextView | ( |  | ) | `[virtual]`

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

Gtk::TextView::TextView | ( | const Glib::RefPtr< TextBuffer >& | buffer | ) | `[explicit]`

## Member Function Documentation

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.

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 the Gdk::Window in question, and that these coordinates have no sane relationship 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), you'll need to compute the child's correct position in buffer coordinates any time scrolling occurs or buffer changes occur, and then call move_child() to update the child's position. Unfortunately there's no good way to detect that scrolling has occurred, using the current API; a possible hack would be to update all child positions when the scroll adjustments change or the text buffer changes. See bug 64518 on bugzilla.gnome.org for status of fixing this issue.

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.

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.

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.

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 `0`.
  window_y | Window y coordinate return location or `0`.

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.

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.

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

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.

Since gtkmm 2.22:

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

Deprecated:
  Use scroll_to()

void Gtk::TextView::scroll_to | ( | const Glib::RefPtr< TextBuffer::Mark >& | mark,
|  | double | within_margin,
|  | double | xalign,
|  | double | yalign
| ) |  |

Scrolls the TextView so that iter is on the screen, in the position indicated by xalign and yalign, possibly not scrolling at all.

The effective screen for purposes of this function is reduced by a margin of size within_margin.

Parameters:

  mark | An mark 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.
  yalign | vertical alignment of mark within visible area. An alignment of 0.0 indicates top, 1.0 indicates bottom, 0.5 means center.

bool Gtk::TextView::scroll_to | ( | TextBuffer::iterator& | iter,
|  | double | within_margin = `0`
| ) |  |

Scrolls the TextView so that iter is on the screen, by scrolling the minimal distance to get the mark onscreen, possibly not scrolling at all.

The effective screen for purposes of this function is reduced by a margin of size within_margin.

Note:
  This function uses the currently-computed height of the lines in the text buffer. Note that line heights are computed in an idle handler; so this function may not have the desired effect if it's called before the height computations. 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.

Returns:
  true if scrolling occurred.

Parameters:

  accepts_tab | `true` if pressing the Tab key should insert a tab character, `false`, if pressing the Tab key should move the keyboard focus.

void Gtk::TextView::set_border_window_size | ( | TextWindowType | type,
|  | int | size
| ) |  |

Sets the width of Gtk::TEXT_WINDOW_LEFT or Gtk::TEXT_WINDOW_RIGHT, or the height of Gtk::TEXT_WINDOW_TOP or Gtk::TEXT_WINDOW_BOTTOM.

Automatically destroys the corresponding window if the size is set to 0, and creates the window if the size is set to non-zero. This function can only be used for the "border windows," it doesn't work with Gtk::TEXT_WINDOW_WIDGET, Gtk::TEXT_WINDOW_TEXT, or Gtk::TEXT_WINDOW_PRIVATE.

Parameters:

  type | Window to affect.
  size | Width or height of the window.

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

Sets buffer as the buffer being displayed by text_view.

The previous buffer displayed by the text view is unreferenced, and a reference is added to buffer. If you owned a reference to buffer before passing it to this function, you must remove that reference yourself; Gtk::TextView will not "adopt" it.

Parameters:

  buffer | A Gtk::TextBuffer.

void Gtk::TextView::set_cursor_visible | ( | bool | setting = `true` | ) |

Toggles whether the insertion point is displayed.

A buffer with no editable text probably shouldn't have a visible cursor, so you may want to turn the cursor off.

Parameters:

  setting | Whether to show the insertion cursor.

void Gtk::TextView::set_editable | ( | bool | setting = `true` | ) |

Sets the default editability of the Gtk::TextView.

You can override this default setting with tags in the buffer, using the "editable" attribute of tags.

Tags in the view's buffer may override the default.

Parameters:

  justification | Justification.

void Gtk::TextView::set_left_margin | ( | int | left_margin | ) |

Sets the default left margin for text in text_view.

Tags in the buffer may override the default.

Parameters:

  left_margin | Left margin in pixels.

void Gtk::TextView::set_overwrite | ( | bool | overwrite = `true` | ) |

Changes the Gtk::TextView overwrite mode.

void Gtk::TextView::set_pixels_above_lines | ( | int | pixels_above_lines | ) |

Sets the default number of blank pixels above paragraphs in text_view.

Tags in the buffer for text_view may override the defaults.

Parameters:

  pixels_above_lines | Pixels above paragraphs.

void Gtk::TextView::set_pixels_below_lines | ( | int | pixels_below_lines | ) |

Sets the default number of pixels of blank space to put below paragraphs in text_view.

May be overridden by tags applied to text_view's buffer.

Parameters:

  pixels_below_lines | Pixels below paragraphs.

void Gtk::TextView::set_pixels_inside_wrap | ( | int | pixels_inside_wrap | ) |

Sets the default number of pixels of blank space to leave between display/wrapped lines within a paragraph.
