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

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

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 :

yalign :

vertical alignment of mark within visible area

Returns :

TRUE if scrolling occurred

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);

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 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 :

                                                         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 :

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.

                                                         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.

text_view :

a GtkTextView

win :

window to get

Returns :

a GdkWindow, or NULL

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.

text_view :

a GtkTextView

window :

a window type

Returns :

the window type.

gtk_text_view_set_border_window_size ()

void                gtk_text_view_set_border_window_size

                                                         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.

text_view :

a GtkTextView

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

Gets the width of the specified border window. See gtk_text_view_set_border_window_size().

text_view :

a GtkTextView

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.

                                                         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.

                                                         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.

                                                         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.

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.

iter :

a GtkTextIter

count :

number of characters to move (negative moves left, positive moves right)

Returns :

                                                         GtkTextChildAnchor *anchor);

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

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.

The ::move-cursor signal is a keybinding signal which gets emitted when the user initiates a cursor movement. If the cursor is not visible in text_view, this signal causes the viewport to be moved instead.

Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control scrolling programmatically.

The default bindings for this signal come in two variants, the variant with the Shift modifier extends the selection, the variant without the Shift modifer does not. There are too many key combinations to list them all here.

  • Arrow keys move by individual characters/lines
  • Ctrl-arrow key combinations move by words/paragraphs
  • Home/End keys move to the ends of the buffer
  • PageUp/PageDown keys move vertically by pages
  • Ctrl-PageUp/PageDown keys move horizontally by pages
