= class Gtk::TextView

Widget that The Gtk::TextView widget displays a an associated Gtk::TextBuffer.

If you need a simple widget that can hold text, both for viewing and manipulating the text, this is the right widget to use.

There is also another one for Gtk::SourceView, which may add some specialized functions/methods.

== Object Hierarchy

  * GLib::Instantiatable
    * GLib::Object
      * GLib::InitiallyUnowned
        * Gtk::Object
          * Gtk::Widget
            * Gtk::Container
              * Gtk::TextView

== Class Methods

--- Gtk::TextView.new(buffer = nil)

    Creates a new Gtk::TextView widget displaying the buffer. One buffer can be shared among many widgets. buffer may be nil to create a default buffer.
    * buffer: a Gtk::TextBuffer
    * Returns: a new Gtk::TextView

== Instance Methods

--- buffer

    Returns the Gtk::TextBuffer being displayed by the Gtk::TextView.
    * Returns: a Gtk::TextBuffer

--- buffer=(buffer)

    Sets buffer as the buffer being displayed by the Gtk::TextView.
    * buffer: a Gtk::TextBuffer
    * Returns: buffer

--- set_buffer(buffer)

    Same as Gtk::TextView#buffer=.
    * buffer: a Gtk::TextBuffer
    * Returns: self

--- scroll_to_mark(mark, within_margin, use_align, xalign, yalign)

    Scrolls the Gtk::TextView so that mark is on the screen in the position indicated by xalign and yalign. An alignment of 0.0 indicates left or top, 1.0 indicates right or bottom, 0.5 means center. If use_align is false, the text scrolls the minimal distance to get the mark onscreen, possibly not scrolling at all. The effective screen for purposes of this method is reduced by a margin of size within_margin.
    * mark: a Gtk::TextMark
    * within_margin: margin as a 0.0, 0.5 fraction of screen size
    * use_align: whether to use alignment arguments (if false, just get the mark onscreen)
    * xalign: horizontal alignment of mark within visible area.
    * yalign: vertical alignment of mark within visible area
    * Returns: self

--- scroll_to_iter(iter, within_margin, use_align, xalign, yalign)

    Scrolls the Gtk::TextView so that iter is on the screen in the position indicated by xalign and yalign. An alignment of 0.0 indicates left or top, 1.0 indicates right or bottom, 0.5 means center. If use_align is false, the text scrolls the minimal distance to get the mark onscreen, possibly not scrolling at all. The effective screen for purposes of this method is reduced by a margin of size within_margin. NOTE: This method uses the currently-computed height of the lines in the text buffer. Note that line heights are computed in an idle handler; so this method may not have the desired effect if it's called before the height computations. To avoid oddness, consider using Gtk::TextView#scroll_to_mark which saves a point to be scrolled to after line validation.
    * iter: a Gtk::TextIter
    * within_margin: margin as a 0.0, 0.5 fraction of screen size
    * use_align: whether to use alignment arguments (if false, just get the mark onscreen)
    * xalign: horizontal alignment of mark within visible area.
    * yalign: vertical alignment of mark within visible area
    * Returns: true if scrolling occurred

--- scroll_mark_onscreen(mark)

    Scrolls the Gtk::TextView the minimum distance such that mark is contained within the visible area of the widget.
    * mark: a mark in the buffer for the Gtk::TextView
    * Returns: self

--- move_mark_onscreen(mark)

    Moves a mark within the buffer so that it's located within the currently-visible text area.
    * mark: a Gtk::TextMark
    * Returns: true if the mark moved (wasn't already onscreen)

--- place_cursor_onscreen

    Moves the cursor to the currently visible region of the buffer, if it isn't there already.
    * Returns: true if the cursor had to be moved.

--- visible_rect

    Returns the currently-visible region of the buffer, in buffer coordinates. Convert to window coordinates with Gtk::TextView#buffer_to_window_coords.
    * Returns: Gdk::Rectangle

--- get_iter_location(iter)

    Gets a Gdk::Rectangle which roughly contains the character at iter. The Gdk::Rectangle position is in buffer coordinates; use Gtk::TextView#buffer_to_window_coords to convert these coordinates to coordinates for one of the windows in the text view.
    * iter : a GtkTextIter
    * Returns: a Gdk::Rectangle which is the bounds of the character at iter

--- get_line_at_y(y)

    Gets the Gtk::TextIter at the start of the line containing the coordinate y. y is in buffer coordinates, convert from window coordinates with Gtk::TextView#window_to_buffer_coords. If non-nil, line_top will be the coordinate of the top edge of the line.
    * y : a y coordinate
    * Returns [target_iter, line_top]
       * target_iter : a Gtk::TextIter
       * line_top: top coordinate of the line

--- get_line_yrange(iter)

    Gets the y coordinate of the top of the line containing iter, and the height of the line. The coordinate is a buffer coordinate; convert to window coordinates with Gtk::TextView#buffer_to_window_coords.
    * iter : a GtkTextIter
    * Returns: [y, height]
       * y: a y coordinate
       * height: a height

--- get_iter_at_location(x, y)

    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 Gtk::TextView#window_to_buffer_coords.
    * x: x position, in buffer coordinates
    * y: y position, in buffer coordinates
    * Returns: a Gtk::TextIter

--- get_iter_at_position(x, y)

    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 Gtk::TextView#window_to_buffer_coords.
    Note that this is diffferent from Gtk::TextView#get_iter_at_location, which returns cursor locations, i.e. positions between characters.  ((* Since 2.6 *))
    * x: x position, in buffer coordinates
    * y: y position, in buffer coordinates
    * Returns: [iter, trailing]

    Note that you can't convert coordinates for a nonexisting window (see Gtk::TextView#set_border_window_size).
    * win_type: a ((<GtkTextWindowType|Gtk::TextView#GtkTextWindowType>)) except Gtk::TextView::WINDOW_PRIVATE
    * buffer_x: buffer x coordinate
    * buffer_y: buffer y coordinate
    * Returns: [window_x, window_y]

    Note that you can't convert coordinates for a nonexisting window (see Gtk::TextView#set_border_window_size).
    * win_type : a ((<GtkTextWindowType|Gtk::TextView#GtkTextWindowType>)) except Gtk::TextView::WINDOW_PRIVATE
    * window_x: window x coordinate
    * window_y: window y coordinate
    * Returns: [buffer_x, buffer_y]
       * buffer_x: buffer x coordinate
       * buffer_y: buffer y coordinate

--- get_window(win_type)

    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 nil and nonexistent if their width or height is 0, and are nonexistent before the widget has been realized.
    * win_type: a ((<GtkTextWindowType|Gtk::TextView#GtkTextWindowType>)) to get
    * Returns: a Gdk::Window, or nil

--- get_window_type(window)

    Usually used to find out which window an event corresponds to. If you connect to an event signal on Gtk::TextView, this method should be called on event.window to see which window it was.
    * window: a window type
    * Returns: the ((<GtkTextWindowType|Gtk::TextView#GtkTextWindowType>))

--- get_border_window_size(type)

    Gets the width of the specified border window. See Gtk::TextView#set_border_window_size.

    * Returns: width of window

--- set_border_window_size(type, size)

    Sets the width of Gtk::TextView::WINDOW_LEFT or Gtk::TextView::WINDOW_RIGHT, or the height of Gtk::TextView::WINDOW_TOP or Gtk::TextView::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 method can only be used for the "border windows," it doesn't work with Gtk::TextView::WINDOW_WIDGET, Gtk::TextView::WINDOW_TEXT, or Gtk::TextView::WINDOW_PRIVATE.
    * type: ((<GtkTextWindowType|Gtk::TextView#GtkTextWindowType>)) to affect
    * size: width or height of the window
    * Returns: self

--- forward_display_line(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.
    * iter: a Gtk::TextIter
    * Returns: true if iter was moved and is not on the end iterator

--- backward_display_line(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.
    * iter: a Gtk::TextIter
    * Returns: true if iter was moved and is not on the end iterator

--- forward_display_line_end(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.
    * iter: a Gtk::TextIter
    * Returns: true if iter was moved and is not on the end iterator

--- backward_display_line_start(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.
    * iter: a Gtk::TextIter
    * Returns: true if iter was moved and is not on the end iterator

--- starts_display_line(iter)

    * anchor: a Gtk::TextChildAnchor in the Gtk::TextBuffer for the Gtk::TextView
    * Returns: self

--- add_child_in_window(child, which_window, xpos, ypos)

    Adds a child at fixed coordinates in one of the text widget's windows. The window must have nonzero size (see Gtk::TextView#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::TextView::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 Gtk::TextView#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.
