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().

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.

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.

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.

gtk_text_view_get_hadjustment ()

GtkAdjustment *
gtk_text_view_get_hadjustment (GtkTextView *text_view);

Gets the horizontal-scrolling GtkAdjustment.

Since 2.22

gtk_text_view_get_vadjustment ()

GtkAdjustment *
gtk_text_view_get_vadjustment (GtkTextView *text_view);

Gets the vertical-scrolling GtkAdjustment.

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 .

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.

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.

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.

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.

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().

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.

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.

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.

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().

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.

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()).

gtk_text_view_window_to_buffer_coords ()

void
gtk_text_view_window_to_buffer_coords (GtkTextView *text_view,
                                       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()).

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.

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.

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,” it doesn’t work with GTK_TEXT_WINDOW_WIDGET, GTK_TEXT_WINDOW_TEXT, or GTK_TEXT_WINDOW_PRIVATE.

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().

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.

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.

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.

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.

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.

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.

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 .

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().

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().

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.

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.

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().

gtk_text_view_set_wrap_mode ()

void
gtk_text_view_set_wrap_mode (GtkTextView *text_view,
                             GtkWrapMode wrap_mode);

Sets the line wrapping for the view.

gtk_text_view_get_wrap_mode ()

                                  gboolean setting);

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.

gtk_text_view_get_cursor_visible ()

gboolean
gtk_text_view_get_cursor_visible (GtkTextView *text_view);

Find out whether the cursor is being displayed.

gtk_text_view_set_overwrite ()

                        PangoTabArray *tabs);

Sets the default tab stops for paragraphs in text_view . Tags in the buffer may override the default.

gtk_text_view_get_tabs ()

PangoTabArray *
gtk_text_view_get_tabs (GtkTextView *text_view);

Gets the default tabs for text_view . Tags in the buffer may override the defaults. The returned array will be NULL if “standard” (8-space) tabs are used. Free the return value with pango_tab_array_free().

gtk_text_view_set_accepts_tab ()

void
gtk_text_view_set_accepts_tab (GtkTextView *text_view,
                               gboolean accepts_tab);

Sets the behavior of the text widget when the Tab key is pressed. If accepts_tab is TRUE, a tab character is inserted. If accepts_tab is FALSE the keyboard focus is moved to the next widget in the focus chain.

Since 2.4

gtk_text_view_get_accepts_tab ()

gboolean
gtk_text_view_get_accepts_tab (GtkTextView *text_view);

Returns whether pressing the Tab key inserts a tab characters. gtk_text_view_set_accepts_tab().

Since 2.4

gtk_text_view_get_default_attributes ()

GtkTextAttributes *
gtk_text_view_get_default_attributes (GtkTextView *text_view);

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_text_iter_get_attributes() in order to get the attributes in effect at a given text position.

The return value is a copy owned by the caller of this function, and should be freed.

gtk_text_view_im_context_filter_keypress ()

gboolean
gtk_text_view_im_context_filter_keypress
                               (GtkTextView *text_view,
                                GdkEventKey *event);

Allow the GtkTextView 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 GtkTextView.

If you need to add items to the context menu, connect to this signal and append your items to the popup , which will be a GtkMenu in this case.

If “populate-all” is TRUE, this signal will also be emitted to populate touch popups. In this case, popup will be a different container, e.g. a GtkToolbar.

The signal handler should not make assumptions about the type of widget , but check whether popup is a GtkMenu or GtkToolbar or another kind of container.

Flags: Run Last

The “preedit-changed” signal

void
user_function (GtkTextView *text_view,
               gchar       *preedit,
