## Detailed Description

Multi-line text editing widget.

It displays a Gtk::TextBuffer.

The TextView widget looks like this:

## 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 `nullptr`.
  window_y | Window y coordinate return location or `nullptr`.

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

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.

int Gtk::TextView::get_border_window_size | ( | TextWindowType | type | ) | const

Gets the width of the specified border window.

See set_border_window_size().

Parameters

  type | Window to return size from.

Returns
  Width of window.

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

Returns the Gtk::TextBuffer being displayed by this text view.

Returns
  A Gtk::TextBuffer.

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

Returns the Gtk::TextBuffer being displayed by this text view.

The reference count on the buffer is not incremented; the caller of this function won't own a new reference.

Find out whether the cursor is being displayed.

Returns
  Whether the insertion mark is visible.

TextAttributes Gtk::TextView::get_default_attributes | ( |  | ) | const

Obtains a copy of the default text attributes.

These are the attributes used for text unless a tag overrides them. You'd typically pass the default attributes in to Gtk::TextIter::get_attributes() in order to get the attributes in effect at a given text position.

Returns
  A new Gtk::TextAttributes.

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

Returns the default editability of the Gtk::TextView.

Tags in the buffer may override this setting for some ranges of text.

Returns
  Whether text is editable by default.

Gtk::Adjustment* Gtk::TextView::get_hadjustment | ( |  | ) |

Gets the horizontal-scrolling Gtk::Adjustment.

Since gtkmm 2.22:

Returns
  Pointer to the horizontal Gtk::Adjustment.

const Gtk::Adjustment* Gtk::TextView::get_hadjustment | ( |  | ) | const

Gets the horizontal-scrolling Gtk::Adjustment.

Since gtkmm 2.22:

Returns
  Pointer to the horizontal Gtk::Adjustment.

int Gtk::TextView::get_indent | ( |  | ) | const

Gets the default indentation of paragraphs in text_view.

Tags in the view's buffer may override the default. The indentation may be negative.

Returns
  Number of pixels of indentation.

void Gtk::TextView::get_iter_at_location | ( | TextBuffer::iterator& | iter,
|  | int | x,
|  | int | y
| ) |  | const

Retrieves the iterator at buffer coordinates x and y.

Buffer coordinates are coordinates for the entire buffer, not just the currently-displayed portion. If you have coordinates from an event, you have to convert those to buffer coordinates with window_to_buffer_coords().

Parameters

  iter | A Gtk::TextIter.
  x | X position, in buffer coordinates.
  y | Y position, in buffer coordinates.

void Gtk::TextView::get_iter_at_position | ( | TextBuffer::iterator& | iter,

|  | int | y
| ) |  | const

Retrieves the iterator pointing to the character at buffer coordinates x and y.

Buffer coordinates are coordinates for the entire buffer, not just the currently-displayed portion. If you have coordinates from an event, you have to convert those to buffer coordinates with window_to_buffer_coords().

y is in buffer coordinates, convert from window coordinates with window_to_buffer_coords(). If non-`nullptr`, line_top will be filled with the coordinate of the top edge of the line.

Parameters

  target_iter | A Gtk::TextIter.
  y | A y coordinate.
  line_top | Return location for top coordinate of the line.

Retrieves the Gdk::Window corresponding to an area of the text view; possible windows include the overall widget window, child windows on the left, right, top, bottom, and the window that displays the text buffer.

Windows are `nullptr` and nonexistent if their width or height is 0, and are nonexistent before the widget has been realized.

Parameters

  win | Window to get.

Returns
  A Gdk::Window, or `nullptr`.

Glib::RefPtr<const Gdk::Window> Gtk::TextView::get_window | ( | TextWindowType | win | ) | const

TextWindowType Gtk::TextView::get_window_type | ( | const Glib::RefPtr< Gdk::Window >& | window | ) |

Usually used to find out which window an event corresponds to.

If you connect to an event signal on text_view, this function should be called on `event->window` to see which window it was.

Parameters

  window | A window type.

Returns
  The window type.

bool Gtk::TextView::im_context_filter_keypress | ( | GdkEventKey * | event | ) |

Allow the Gtk::TextView input method to internally handle key press and release events.

If this function returns `true`, then no further processing should be done for this key event. See gtk_im_context_filter_keypress().

Note that you are expected to call this function from your handler when overriding key event handling. This is needed in the case when you need to insert your own key handling between the input method and the default key event handling of the Gtk::TextView.

[C example ellipted]

Since gtkmm 2.22:

Parameters

  event | The key event.

Returns
  `true` if the input method handled the key event.

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

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.

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()

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.

| ) |  |

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.

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.

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.
