Implemented Interfaces
GtkTextView implements AtkImplementorIface, GtkBuildable and GtkScrollable.
Includes
#include <gtk/gtk.h>
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.
CSS nodes
GtkTextView has a main css node with name textview and style class .view, and subnodes for each of the border windows, and the main text area, with names border and text, respectively. The border nodes each get one of the style classes .left, .right, .top or .bottom.
A node representing the selection will appear below the text node.
If a context menu is opened, the window node will appear as a subnode of the main node.
Functions
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.
Parameters
buffer |
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.
Parameters
text_view | ||
buffer | [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.
Parameters
text_view |
gtk_text_view_get_hadjustment ()
GtkAdjustment *
gtk_text_view_get_hadjustment (GtkTextView *text_view
);
gtk_text_view_get_hadjustment
has been deprecated since version 3.0 and should not be used in newly-written code.
Gets the horizontal-scrolling GtkAdjustment.
Parameters
text_view |
Since: 2.22
gtk_text_view_get_vadjustment ()
GtkAdjustment *
gtk_text_view_get_vadjustment (GtkTextView *text_view
);
gtk_text_view_get_vadjustment
has been deprecated since version 3.0 and should not be used in newly-written code.
Gets the vertical-scrolling GtkAdjustment.
Parameters
text_view |
Since: 2.22
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
.
Parameters
text_view | ||
mark | ||
within_margin | margin as a [0.0,0.5) fraction of screen size | |
use_align | whether to use alignment arguments (if | |
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.
Parameters
text_view | ||
iter | ||
within_margin | margin as a [0.0,0.5) fraction of screen size | |
use_align | whether to use alignment arguments (if | |
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.
Parameters
text_view | ||
mark | a mark in the buffer for |
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.
Parameters
text_view | ||
mark |
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.
Parameters
text_view |
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()
.
Parameters
text_view | ||
visible_rect | rectangle to fill. | [out] |
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.
Parameters
text_view | ||
iter | ||
location | bounds of the character at | [out] |
gtk_text_view_get_cursor_locations ()
void gtk_text_view_get_cursor_locations (GtkTextView *text_view
,const GtkTextIter *iter
,GdkRectangle *strong
,GdkRectangle *weak
);
Given an iter
within a text layout, determine the positions of the strong and weak cursors if the insertion point is at that iterator. 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 NULL
, 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 gtk_text_view_buffer_to_window_coords()
to convert these coordinates to coordinates for one of the windows in the text view.
Parameters
text_view | ||
iter | a GtkTextIter. | [allow-none] |
strong | location to store the strong cursor position (may be | [out][allow-none] |
weak | location to store the weak cursor position (may be | [out][allow-none] |
Since: 3.0
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.
Parameters
text_view | ||
target_iter | a GtkTextIter. | [out] |
y | a y coordinate | |
line_top | return location for top coordinate of the line. | [out] |
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()
.
Parameters
text_view | ||
iter | ||
y | return location for a y coordinate. | [out] |
height | return location for a height. | [out] |
gtk_text_view_get_iter_at_location ()
gboolean 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()
.
Parameters
text_view | ||
iter | a GtkTextIter. | [out] |
x | x position, in buffer coordinates | |
y | y position, in buffer coordinates |
Returns
TRUE
if the position is over text
gtk_text_view_get_iter_at_position ()
gboolean 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.
Parameters
text_view | ||
iter | a GtkTextIter. | [out] |
trailing | if non- | [out][allow-none] |
x | x position, in buffer coordinates | |
y | y position, in buffer coordinates |
Returns
TRUE
if the position is over text
Since: 2.6
gtk_text_view_buffer_to_window_coords ()
void gtk_text_view_buffer_to_window_coords (GtkTextView *text_view
,GtkTextWindowType win
,gint buffer_x
,gint buffer_y
,gint *window_x
,gint *window_y
);
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 gtk_text_view_set_border_window_size()
).
Parameters
text_view | ||
win | a GtkTextWindowType, except | |
buffer_x | buffer x coordinate | |
buffer_y | buffer y coordinate | |
window_x | window x coordinate return location or | [out][allow-none] |
window_y | window y coordinate return location or | [out][allow-none] |
gtk_text_view_window_to_buffer_coords ()

,GtkTextWindowType win
,gint window_x
,gint window_y
,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()
).
Parameters
text_view | ||
win | a GtkTextWindowType except | |
window_x | window x coordinate | |
window_y | window y coordinate | |
buffer_x | buffer x coordinate return location or | [out][allow-none] |
buffer_y | buffer y coordinate return location or | [out][allow-none] |
gtk_text_view_get_window ()
GdkWindow * gtk_text_view_get_window (GtkTextView *text_view
,GtkTextWindowType win
);
Retrieves the GdkWindow 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 NULL
and nonexistent if their width or height is 0, and are nonexistent before the widget has been realized.
Parameters
text_view | ||
win | window to get |
gtk_text_view_get_window_type ()
GtkTextWindowType gtk_text_view_get_window_type (GtkTextView *text_view
,GdkWindow *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
text_view | ||
window | a window type |
Returns
the window type.
gtk_text_view_set_border_window_size ()
void gtk_text_view_set_border_window_size (GtkTextView *text_view
,GtkTextWindowType type
,gint 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”, and it won’t work with GTK_TEXT_WINDOW_WIDGET
, GTK_TEXT_WINDOW_TEXT
, or GTK_TEXT_WINDOW_PRIVATE
.
Parameters
text_view | ||
type | window to affect | |
size | width or height of the window |
gtk_text_view_get_border_window_size ()
gint gtk_text_view_get_border_window_size (GtkTextView *text_view
,GtkTextWindowType type
);
Gets the width of the specified border window. See gtk_text_view_set_border_window_size()
.
Parameters
text_view | ||
type | window to return size from |
Returns
width of window
gtk_text_view_forward_display_line ()
gboolean gtk_text_view_forward_display_line (GtkTextView *text_view
,GtkTextIter *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 GtkTextBuffer.
Parameters
text_view | ||
iter |
Returns
TRUE
if iter
was moved and is not on the end iterator
gtk_text_view_backward_display_line ()
gboolean gtk_text_view_backward_display_line (GtkTextView *text_view
,GtkTextIter *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 GtkTextBuffer.
Parameters
text_view | ||
iter |
Returns
TRUE
if iter
was moved and is not on the end iterator
gtk_text_view_forward_display_line_end ()
gboolean gtk_text_view_forward_display_line_end (GtkTextView *text_view
,GtkTextIter *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 GtkTextBuffer.
Parameters
text_view | ||
iter |
Returns
TRUE
if iter
was moved and is not on the end iterator
gtk_text_view_backward_display_line_start ()
gboolean gtk_text_view_backward_display_line_start (GtkTextView *text_view
,GtkTextIter *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 GtkTextBuffer.
Parameters
text_view | ||
iter |
Returns
TRUE
if iter
was moved and is not on the end iterator
gtk_text_view_starts_display_line ()
gboolean gtk_text_view_starts_display_line (GtkTextView *text_view
,const GtkTextIter *iter
);
Determines whether iter
is at the start of a display line. See gtk_text_view_forward_display_line()
for an explanation of display lines vs. paragraphs.
Parameters
text_view | ||
iter |
Returns
TRUE
if iter
begins a wrapped line
gtk_text_view_move_visually ()
gboolean gtk_text_view_move_visually (GtkTextView *text_view
,GtkTextIter *iter
,gint 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
text_view | ||
iter | ||
count | number of characters to move (negative moves left, positive moves right) |
Returns
TRUE
if iter
moved and is not on the end iterator
gtk_text_view_add_child_at_anchor ()
void gtk_text_view_add_child_at_anchor (GtkTextView *text_view
,GtkWidget *child
,GtkTextChildAnchor *anchor
);
Adds a child widget in the text buffer, at the given anchor
.
Parameters
text_view | ||
child | ||
anchor | a GtkTextChildAnchor in the GtkTextBuffer for |
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()
.
Parameters
anchor |
Returns
list of widgets anchored at anchor
.
[element-type GtkWidget][transfer container]
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.
Parameters
anchor |
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 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) it will move with the scrolling as needed.
Parameters
text_view | ||
child | ||
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 |
gtk_text_view_move_child ()
void gtk_text_view_move_child (GtkTextView *text_view
,GtkWidget *child
,gint xpos
,gint ypos
);
Updates the position of a child, as for gtk_text_view_add_child_in_window()
.
Parameters
text_view | ||
child | child widget already added to the text view | |
xpos | new X position in window coordinates | |
ypos | new Y position in window coordinates |
gtk_text_view_set_wrap_mode ()
void gtk_text_view_set_wrap_mode (GtkTextView *text_view

Returns
the line wrap setting
gtk_text_view_set_editable ()
void gtk_text_view_set_editable (GtkTextView *text_view
,gboolean setting
);
Sets the default editability of the GtkTextView. You can override this default setting with tags in the buffer, using the “editable” attribute of tags.
Parameters
text_view | ||
setting | whether it’s editable |
gtk_text_view_get_editable ()
gboolean
gtk_text_view_get_editable (GtkTextView *text_view
);

whether text is editable by default
gtk_text_view_set_cursor_visible ()
void gtk_text_view_set_cursor_visible (GtkTextView *text_view
,gboolean setting
);
Toggles whether the insertion point should be displayed. A buffer with no editable text probably shouldn’t have a visible cursor, so you may want to turn the cursor off.
Note that this property may be overridden by the “gtk-keynave-use-caret” settings.
Parameters
text_view | ||
setting | whether to show the insertion cursor |
gtk_text_view_get_cursor_visible ()
gboolean
gtk_text_view_get_cursor_visible (GtkTextView *text_view
);

Parameters
text_view |
Returns
whether the insertion mark is visible
gtk_text_view_reset_cursor_blink ()
void
gtk_text_view_reset_cursor_blink (GtkTextView *text_view
);
Ensures that the cursor is shown (i.e. not in an 'off' blink interval) and resets the time that it will stay blinking (or visible, in case blinking is disabled).
This function should be called in response to user input (e.g. from derived classes that override the textview's “key-press-event” handler).
Parameters
