## Description

You may wish to begin by reading the text widget conceptual overview which gives an overview of all the objects and data types related to the text widget and how they work together.

## Details

### GtkTextView

    typedef struct _GtkTextView GtkTextView;

### enum GtkTextWindowType

    typedef enum
    {
      GTK_TEXT_WINDOW_PRIVATE,
      GTK_TEXT_WINDOW_WIDGET,
      GTK_TEXT_WINDOW_TEXT,
      GTK_TEXT_WINDOW_LEFT,
      GTK_TEXT_WINDOW_RIGHT,
      GTK_TEXT_WINDOW_TOP,
      GTK_TEXT_WINDOW_BOTTOM
    } GtkTextWindowType;

### gtk_text_view_new ()

    GtkWidget *         gtk_text_view_new                   (void);

Creates a new GtkTextView. If you don't call `gtk_text_view_set_buffer()` before using the text view, an empty default buffer will be created for you. Get the buffer with `gtk_text_view_get_buffer()`. If you want to specify your own buffer, consider `gtk_text_view_new_with_buffer()`.

Returns : | a new GtkTextView

### gtk_text_view_new_with_buffer ()

    GtkWidget *         gtk_text_view_new_with_buffer       (GtkTextBuffer *buffer);

Creates a new GtkTextView widget displaying the buffer `buffer`. One buffer can be shared among many widgets. `buffer` may be `NULL` to create a default buffer, in which case this function is equivalent to `gtk_text_view_new()`. The text view adds its own reference count to the buffer; it does not take over an existing reference.

`buffer` : | a GtkTextBuffer
Returns : | a new GtkTextView.

### gtk_text_view_set_buffer ()

    void                gtk_text_view_set_buffer            (GtkTextView *text_view,
                                                             GtkTextBuffer *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; GtkTextView will not "adopt" it.

`text_view` : | a GtkTextView
`buffer` : | a GtkTextBuffer. allow-none.

### gtk_text_view_get_buffer ()

    GtkTextBuffer *     gtk_text_view_get_buffer            (GtkTextView *text_view);

Returns the GtkTextBuffer 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.

`text_view` : | a GtkTextView
Returns : | a GtkTextBuffer. transfer none.

### gtk_text_view_scroll_to_mark ()

    void                gtk_text_view_scroll_to_mark        (GtkTextView *text_view,
                                                             GtkTextMark *mark,
                                                             gdouble within_margin,
                                                             gboolean use_align,
                                                             gdouble xalign,
                                                             gdouble yalign);

Scrolls `text_view` 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 function is reduced by a margin of size `within_margin`.

`text_view` : | a GtkTextView
`mark` : | a GtkTextMark
`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

### gtk_text_view_scroll_to_iter ()

    gboolean            gtk_text_view_scroll_to_iter        (GtkTextView *text_view,
                                                             GtkTextIter *iter,
                                                             gdouble within_margin,
                                                             gboolean use_align,
                                                             gdouble xalign,
                                                             gdouble yalign);

Scrolls `text_view` 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 function is reduced by a margin of size `within_margin`.

Note that this function uses the currently-computed height of the lines in the text buffer. 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.

`text_view` : | a GtkTextView
`iter` : | a GtkTextIter
`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

### gtk_text_view_scroll_mark_onscreen ()

    void                gtk_text_view_scroll_mark_onscreen  (GtkTextView *text_view,
                                                             GtkTextMark *mark);

Scrolls `text_view` the minimum distance such that `mark` is contained within the visible area of the widget.

`text_view` : | a GtkTextView
`mark` : | a mark in the buffer for `text_view`

### gtk_text_view_move_mark_onscreen ()

    gboolean            gtk_text_view_move_mark_onscreen    (GtkTextView *text_view,
                                                             GtkTextMark *mark);

Moves a mark within the buffer so that it's located within the currently-visible text area.

`text_view` : | a GtkTextView
`mark` : | a GtkTextMark
Returns : | `TRUE` if the mark moved (wasn't already onscreen)

### gtk_text_view_place_cursor_onscreen ()

    gboolean            gtk_text_view_place_cursor_onscreen (GtkTextView *text_view);

Moves the cursor to the currently visible region of the buffer, it it isn't there already.

`text_view` : | a GtkTextView
Returns : | `TRUE` if the cursor had to be moved.

### gtk_text_view_get_visible_rect ()

    void                gtk_text_view_get_visible_rect      (GtkTextView *text_view,
                                                             GdkRectangle *visible_rect);

Fills `visible_rect` with the currently-visible region of the buffer, in buffer coordinates. Convert to window coordinates with `gtk_text_view_buffer_to_window_coords()`.

`text_view` : | a GtkTextView
`visible_rect` : | rectangle to fill

### gtk_text_view_get_iter_location ()

    void                gtk_text_view_get_iter_location     (GtkTextView *text_view,
                                                             const GtkTextIter *iter,
                                                             GdkRectangle *location);

Gets a rectangle which roughly contains the character at `iter`. The rectangle position is in buffer coordinates; use `gtk_text_view_buffer_to_window_coords()` to convert these coordinates to coordinates for one of the windows in the text view.

`text_view` : | a GtkTextView
`iter` : | a GtkTextIter
`location` : | bounds of the character at `iter`

### gtk_text_view_get_line_at_y ()

    void                gtk_text_view_get_line_at_y         (GtkTextView *text_view,
                                                             GtkTextIter *target_iter,
                                                             gint y,
                                                             gint *line_top);

Gets the GtkTextIter at the start of the line containing the coordinate `y`. `y` is in buffer coordinates, convert from window coordinates with `gtk_text_view_window_to_buffer_coords()`. If non-`NULL`, `line_top` will be filled with the coordinate of the top edge of the line.

`text_view` : | a GtkTextView
`target_iter` : | a GtkTextIter
`y` : | a y coordinate
`line_top` : | return location for top coordinate of the line

### gtk_text_view_get_line_yrange ()

    void                gtk_text_view_get_line_yrange       (GtkTextView *text_view,
                                                             const GtkTextIter *iter,
                                                             gint *y,
                                                             gint *height);

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_text_view_buffer_to_window_coords()`.

`text_view` : | a GtkTextView
`iter` : | a GtkTextIter
`y` : | return location for a y coordinate
`height` : | return location for a height

### gtk_text_view_get_iter_at_location ()

    void                gtk_text_view_get_iter_at_location  (GtkTextView *text_view,
                                                             GtkTextIter *iter,
                                                             gint x,
                                                             gint 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_text_view_window_to_buffer_coords()`.

`text_view` : | a GtkTextView
`iter` : | a GtkTextIter
`x` : | x position, in buffer coordinates
`y` : | y position, in buffer coordinates

### gtk_text_view_get_iter_at_position ()

    void                gtk_text_view_get_iter_at_position  (GtkTextView *text_view,
                                                             GtkTextIter *iter,
                                                             gint *trailing,
                                                             gint x,
                                                             gint 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_text_view_window_to_buffer_coords()`.

Note that this is different from `gtk_text_view_get_iter_at_location()`, which returns cursor locations, i.e. positions between characters.

`text_view` : | a GtkTextView
`iter` : | a GtkTextIter
`trailing` : | if non-`NULL`, location to store an integer indicating where in the grapheme the user clicked. It will either be zero, or the number of characters in the grapheme. 0 represents the trailing edge of the grapheme.
`x` : | x position, in buffer coordinates
`y` : | y position, in buffer coordinates

Since 2.6

### gtk_text_view_buffer_to_window_coords ()

                                                            (GtkTextView *text_view,
                                                             GtkTextWindowType win,
                                                             gint buffer_x,
                                                             gint buffer_y,

Converts coordinates on the window identified by `win` to buffer coordinates, storing the result in (`buffer_x`,`buffer_y`).

Note that you can't convert coordinates for a nonexisting window (see `gtk_text_view_set_border_window_size()`).

`text_view` : | a GtkTextView
`win` : | a GtkTextWindowType except GTK_TEXT_WINDOW_PRIVATE
`window_x` : | window x coordinate
`window_y` : | window y coordinate
`buffer_x` : | buffer x coordinate return location

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.

`text_view` : | a GtkTextView
`type` : | window to affect
`size` : | width or height of the window

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 GtkTextBuffer.

`text_view` : | a GtkTextView
`iter` : | a GtkTextIter
Returns : | `TRUE` if `iter` was moved and is not on the end iterator

### gtk_text_view_backward_display_line ()

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 GtkTextBuffer.

`text_view` : | a GtkTextView

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.

Returns : | `TRUE` if `iter` begins a wrapped line

### gtk_text_view_move_visually ()

    gboolean            gtk_text_view_move_visually         (GtkTextView *text_view,
                                                             GtkTextIter *iter,

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.

`text_view` : | a GtkTextView
`iter` : | a GtkTextIter
`count` : | number of characters to move (negative moves left, positive moves right)
Returns : | `TRUE` if `iter` moved and is not on the end iterator

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

`text_view` : | a GtkTextView
`child` : | a GtkWidget
`anchor` : | a GtkTextChildAnchor in the GtkTextBuffer for `text_view`

### GtkTextChildAnchor

    typedef struct _GtkTextChildAnchor GtkTextChildAnchor;

A GtkTextChildAnchor is a spot in the buffer where child widgets can be "anchored" (inserted inline, as if they were characters). The anchor can have multiple widgets anchored, to allow for multiple views.

### gtk_text_child_anchor_new ()

    GtkTextChildAnchor* gtk_text_child_anchor_new           (void);

Creates a new GtkTextChildAnchor. Usually you would then insert it into a GtkTextBuffer with `gtk_text_buffer_insert_child_anchor()`. To perform the creation and insertion in one step, use the convenience function `gtk_text_buffer_create_child_anchor()`.

Returns : | a new GtkTextChildAnchor

### gtk_text_child_anchor_get_widgets ()

    GList*              gtk_text_child_anchor_get_widgets   (GtkTextChildAnchor *anchor);

Gets a list of all widgets anchored at this child anchor. The returned list should be freed with `g_list_free()`.

`anchor` : | a GtkTextChildAnchor
Returns : | list of widgets anchored at `anchor`. element-type GtkWidget. transfer container GtkWidget.

### gtk_text_child_anchor_get_deleted ()

    gboolean            gtk_text_child_anchor_get_deleted   (GtkTextChildAnchor *anchor);

Determines whether a child anchor has been deleted from the buffer. Keep in mind that the child anchor will be unreferenced when removed from the buffer, so you need to hold your own reference (with `g_object_ref()`) if you plan to use this function — otherwise all deleted child anchors will also be finalized.

`anchor` : | a GtkTextChildAnchor
Returns : | `TRUE` if the child anchor has been deleted from its buffer

### gtk_text_view_add_child_in_window ()

    void                gtk_text_view_add_child_in_window   (GtkTextView *text_view,
                                                             GtkWidget *child,
                                                             GtkTextWindowType which_window,
                                                             gint xpos,
                                                             gint ypos);

Adds a child at fixed coordinates in one of the text widget's windows. The window must have nonzero size (see `gtk_text_view_set_border_window_size()`). Note that the child coordinates are given relative to the GdkWindow 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 `gtk_text_view_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.
