Methods / Constructors
Method / Constructor		Defined By
	new Gtk.TextBuffer (Object *properties) Create a new Gtk.TextBuffer Create a new Gtk.TextBuffer Parameters: Object properties*
	new Gtk.TextBuffer.c_new (TextTagTable *table) : Gtk.TextBuffer Create a new Gtk.TextBuffer Create a new Gtk.TextBuffer Parameters: Gtk.TextTagTable table* a tag table, or NULL to create a new one Returns: Gtk.TextBuffer a new text buffer
	add_mark (TextMark *mark, TextIter where) : none Adds the mark at position where. Adds the mark at position where. The mark must not be added to another buffer, and if its name is not NULL* then there must not be another mark in the buffer with the same name. Emits the "mark-set" signal as notification of the mark's initial placement. Parameters: Gtk.TextMark mark Required (not null) the mark to add Gtk.TextIter where Required (not null) location to place mark Returns: none	Gtk.TextBuffer
	add_selection_clipboard (Clipboard *clipboard) : none Adds clipboard* to the list of clipboards in which the selection contents of buffer are available. Adds clipboard to the list of clipboards in which the selection contents of buffer are available. In most cases, clipboard will be the GtkClipboard of type GDK_SELECTION_PRIMARY for a view of buffer. Parameters: Gtk.Clipboard clipboard Required (not null) a GtkClipboard Returns: none	Gtk.TextBuffer
	apply_tag (TextTag *tag, TextIter start, TextIter end) : none Emits the "apply-tag" signal on buffer. Emits the "apply-tag" signal on buffer. The default handler for the signal applies tag* to the given range. Parameters: Gtk.TextTag tag Required (not null) a GtkTextTag Gtk.TextIter start Required (not null) one bound of range to be tagged Gtk.TextIter end Required (not null) other bound of range to be tagged Returns: none	Gtk.TextBuffer
	apply_tag_by_name (String *name, TextIter start, TextIter end) : none Calls gtk_text_tag_table_lookup() on the buffer's tag table to get a GtkTextTag, then calls gtk_text_buffer_apply_tag(). Calls gtk_text_tag_table_lookup() on the buffer's tag table to get a GtkTextTag, then calls gtk_text_buffer_apply_tag(). Parameters: String name* Required (not null) name of a named GtkTextTag Gtk.TextIter start Required (not null) one bound of range to be tagged Gtk.TextIter end Required (not null) other bound of range to be tagged Returns: none	Gtk.TextBuffer
	backspace (TextIter *iter, gboolean interactive, gboolean default_editable) : gboolean Performs the appropriate action as if the user hit the delete key with the cursor at the position specified by iter. Performs the appropriate action as if the user hit the delete key with the cursor at the position specified by iter. In the normal case a single character will be deleted, but when combining accents are involved, more than one character can be deleted, and when precomposed character and accent combinations are involved, less than one character will be deleted. Because the buffer is modified, all outstanding iterators become invalid after calling this function; however, the iter* will be re-initialized to point to the location where text was deleted. Parameters: Gtk.TextIter iter Required (not null) a position in buffer gboolean interactive Required (not null) whether the deletion is caused by user interaction gboolean default_editable Required (not null) whether the buffer is editable by default Returns: gboolean TRUE if the buffer was modified	Gtk.TextBuffer
	begin_user_action () : none Called to indicate that the buffer operations between here and a call to gtk_text_buffer_end_user_action() are part of a single user-visible operation. Called to indicate that the buffer operations between here and a call to gtk_text_buffer_end_user_action() are part of a single user-visible operation. The operations between gtk_text_buffer_begin_user_action() and gtk_text_buffer_end_user_action() can then be grouped when creating an undo stack. GtkTextBuffer maintains a count of calls to gtk_text_buffer_begin_user_action() that have not been closed with a call to gtk_text_buffer_end_user_action(), and emits the "begin-user-action" and "end-user-action" signals only for the outermost pair of calls. This allows you to build user actions from other user actions. The "interactive" buffer mutation functions, such as gtk_text_buffer_insert_interactive(), automatically call begin/end user action around the buffer operations they perform, so there's no need to add extra calls if you user action consists solely of a single call to one of those functions. Returns: none	Gtk.TextBuffer
	copy_clipboard (Clipboard *clipboard) : none Copies the currently-selected text to a clipboard. Copies the currently-selected text to a clipboard. Parameters: Gtk.Clipboard clipboard* Required (not null) the GtkClipboard object to copy to Returns: none	Gtk.TextBuffer
	create_child_anchor (TextIter *iter) : Gtk.TextChildAnchor This is a convenience function which simply creates a child anchor with gtk_text_child_anchor_new() and inserts it into the buffer with gtk_text_buffer_insert_child_anchor(). This is a convenience function which simply creates a child anchor with gtk_text_child_anchor_new() and inserts it into the buffer with gtk_text_buffer_insert_child_anchor(). The new anchor is owned by the buffer; no reference count is returned to the caller of gtk_text_buffer_create_child_anchor(). Parameters: Gtk.TextIter iter* Required (not null) location in the buffer Returns: Gtk.TextChildAnchor the created child anchor	Gtk.TextBuffer
	create_mark (String *mark_name, TextIter where, gboolean left_gravity) : Gtk.TextMark Creates a mark at position where. Creates a mark at position where. If mark_name* is NULL, the mark is anonymous; otherwise, the mark can be retrieved by name using gtk_text_buffer_get_mark(). If a mark has left gravity, and text is inserted at the mark's current location, the mark will be moved to the left of the newly-inserted text. If the mark has right gravity (left_gravity = FALSE), the mark will end up on the right of newly-inserted text. The standard left-to-right cursor is a mark with right gravity (when you type, the cursor stays on the right side of the text you're typing). The caller of this function does not own a reference to the returned GtkTextMark, so you can ignore the return value if you like. Marks are owned by the buffer and go away when the buffer does. Emits the "mark-set" signal as notification of the mark's initial placement. Parameters: String mark_name name for mark, or NULL Gtk.TextIter where Required (not null) location to place mark gboolean left_gravity Required (not null) whether the mark has left gravity Returns: Gtk.TextMark the new GtkTextMark object	Gtk.TextBuffer
	cut_clipboard (Clipboard *clipboard, gboolean default_editable) : none Copies the currently-selected text to a clipboard, then deletes said text if it's editable. Copies the currently-selected text to a clipboard, then deletes said text if it's editable. Parameters: Gtk.Clipboard clipboard* Required (not null) the GtkClipboard object to cut to gboolean default_editable Required (not null) default editability of the buffer Returns: none	Gtk.TextBuffer
	delete (TextIter *start, TextIter end) : none Deletes text between start* and end. Deletes text between start and end. The order of start and end is not actually relevant; gtk_text_buffer_delete() will reorder them. This function actually emits the "delete-range" signal, and the default handler of that signal deletes the text. Because the buffer is modified, all outstanding iterators become invalid after calling this function; however, the start and end will be re-initialized to point to the location where text was deleted. Parameters: Gtk.TextIter start Required (not null) a position in buffer Gtk.TextIter end Required (not null) another position in buffer Returns: none	Gtk.TextBuffer
	delete_interactive (TextIter *start_iter, TextIter end_iter, gboolean default_editable) : gboolean Deletes all editable text in the given range. Deletes all editable text in the given range. Calls gtk_text_buffer_delete() for each editable sub-range of [start,end). start* and end are revalidated to point to the location of the last deleted range, or left untouched if no text was deleted. Parameters: Gtk.TextIter start_iter Required (not null) start of range to delete Gtk.TextIter end_iter Required (not null) end of range gboolean default_editable Required (not null) whether the buffer is editable by default Returns: gboolean whether some text was actually deleted	Gtk.TextBuffer
	delete_mark (TextMark *mark) : none Deletes mark, so that it's no longer located anywhere in the buffer. Deletes mark, so that it's no longer located anywhere in the buffer. Removes the reference the buffer holds to the mark, so if you haven't called g_object_ref() on the mark, it will be freed. Even if the mark isn't freed, most operations on mark* become invalid, until it gets added to a buffer again with gtk_text_buffer_add_mark(). Use gtk_text_mark_get_deleted() to find out if a mark has been removed from its buffer. The "mark-deleted" signal will be emitted as notification after the mark is deleted. Parameters: Gtk.TextMark mark Required (not null) a GtkTextMark in buffer Returns: none	Gtk.TextBuffer
	delete_mark_by_name (String *name) : none Deletes the mark named name; the mark must exist. Deletes the mark named name; the mark must exist. See gtk_text_buffer_delete_mark() for details. Parameters: String name* Required (not null) name of a mark in buffer Returns: none	Gtk.TextBuffer
	delete_selection (gboolean *interactive, gboolean default_editable) : gboolean Deletes the range between the "insert" and "selection_bound" marks, that is, the currently-selected text. Deletes the range between the "insert" and "selection_bound" marks, that is, the currently-selected text. If interactive* is TRUE, the editability of the selection will be considered (users can't delete uneditable text). Parameters: gboolean interactive Required (not null) whether the deletion is caused by user interaction gboolean default_editable Required (not null) whether the buffer is editable by default Returns: gboolean whether there was a non-empty selection to delete	Gtk.TextBuffer
	deserialize (TextBuffer *content_buffer, Atom format, TextIter iter, String data, guint32 length) : gboolean This function deserializes rich text in format format* and inserts it at iter. This function deserializes rich text in format format and inserts it at iter. gtk_text_buffer_register_deserialize_format() or gtk_text_buffer_register_deserialize_tagset() beforehand.

	deserialize_set_can_create_tags (Atom *format, gboolean can_create_tags) : none Use this function to allow a rich text deserialization function to create new tags in the receiving buffer. Use this function to allow a rich text deserialization function to create new tags in the receiving buffer. Note that using this function is almost always a bad idea, because the rich text functions you register should know how to map the rich text format they handler to your text buffers set of tags. The ability of creating new (arbitrary!) tags in the receiving buffer is meant for special rich text formats like the internal one that is registered using gtk_text_buffer_register_deserialize_tagset(), because that format is essentially a dump of the internal structure of the source buffer, including its tag names. You should allow creation of tags only if you know what you are doing, e.g. if you defined a tagset name for your application suite's text buffers and you know that it's fine to receive new tags from these buffers, because you know that your application can handle the newly created tags. Parameters: Gdk.Atom format* Required (not null) a GdkAtom representing a registered rich text format gboolean can_create_tags Required (not null) whether deserializing this format may create tags Returns: none	Gtk.TextBuffer

Equivalent to calling gtk_text_buffer_get_mark() to get the mark named "selection_bound", but very slightly more efficient, and involves less typing. The currently-selected text in buffer is the region between the "selection_bound" and "insert" marks. If "selection_bound" and "insert" are in the same place, then there is no current selection. gtk_text_buffer_get_selection_bounds() is another convenient function for handling the selection, if you just want to know whether there's a selection and what its bounds are. Returns: Gtk.TextMark selection bound mark	Gtk.TextBuffer
	get_selection_bounds (Object *out_values) : gboolean Returns TRUE* if some text is selected; places the bounds of the selection in start and end (if the selection has length 0, then start and end are filled in with the same value). Returns TRUE if some text is selected; places the bounds of the selection in start and end (if the selection has length 0, then start and end are filled in with the same value).

	get_slice (TextIter *start, TextIter end, gboolean include_hidden_chars) : String Returns the text in the range [start,end). Returns the text in the range [start,end). Excludes undisplayed text (text marked with tags that set the invisibility attribute) if 0xFFFC character whenever the buffer contains embedded images, so byte and character indexes into the returned string do correspond to byte and character indexes into the buffer. Contrast with gtk_text_buffer_get_text(). Note that 0xFFFC can occur in normal text as well, so it is not a reliable indicator that a pixbuf or widget is in the buffer. Parameters: Gtk.TextIter start* Required (not null) start of a range Gtk.TextIter end Required (not null) end of a range gboolean include_hidden_chars Required (not null) whether to include invisible text Returns: String an allocated UTF-8 string	Gtk.TextBuffer

	get_tag_table () : Gtk.TextTagTable Get the GtkTextTagTable associated with this buffer. Get the GtkTextTagTable associated with this buffer. Returns: Gtk.TextTagTable the buffer's tag table	Gtk.TextBuffer
	get_text (TextIter *start, TextIter end, gboolean include_hidden_chars) : String Returns the text in the range [start,end). Returns the text in the range [start,end). Excludes undisplayed text (text marked with tags that set the invisibility attribute) if representing embedded images, so byte and character indexes into the returned string do not correspond to byte and character indexes into the buffer. Contrast with gtk_text_buffer_get_slice(). Parameters: Gtk.TextIter start* Required (not null) start of a range Gtk.TextIter end Required (not null) end of a range gboolean include_hidden_chars Required (not null) whether to include invisible text Returns: String an allocated UTF-8 string	Gtk.TextBuffer
	insert (TextIter *iter, String text, gint32 len) : none Inserts len* bytes of text at position iter. Inserts len bytes of text at position iter. If len is -1, entirety. Emits the "insert-text" signal; insertion actually occurs in the default handler for the signal. iter is invalidated when insertion occurs (because the buffer contents change), but the default signal handler revalidates it to point to the end of the inserted text. Parameters: Gtk.TextIter iter Required (not null) a position in the buffer String text Required (not null) text in UTF-8 format gint32 len Required (not null) length of text in bytes, or -1 Returns: none	Gtk.TextBuffer
	insert_at_cursor (String *text, gint32 len) : none Simply calls gtk_text_buffer_insert(), using the current cursor position as the insertion point. Simply calls gtk_text_buffer_insert(), using the current cursor position as the insertion point. Parameters: String text* Required (not null) text in UTF-8 format gint32 len Required (not null) length of text, in bytes Returns: none	Gtk.TextBuffer
	insert_child_anchor (TextIter *iter, TextChildAnchor anchor) : none Inserts a child widget anchor into the text buffer at iter. Inserts a child widget anchor into the text buffer at iter. The anchor will be counted as one character in character counts, and when obtaining the buffer contents as a string, will be represented by the Unicode "object replacement character" 0xFFFC. Note that the "slice" variants for obtaining portions of the buffer as a string include this character for child anchors, but the "text" variants do not. E.g. see gtk_text_buffer_get_slice() and gtk_text_buffer_get_text(). Consider gtk_text_buffer_create_child_anchor() as a more convenient alternative to this function. The buffer will add a reference to the anchor, so you can unref it after insertion. Parameters: Gtk.TextIter iter* Required (not null) location to insert the anchor Gtk.TextChildAnchor anchor Required (not null) a GtkTextChildAnchor Returns: none	Gtk.TextBuffer
	insert_interactive (TextIter *iter, String text, gint32 len, gboolean default_editable) : gboolean Like gtk_text_buffer_insert(), but the insertion will not occur if want to prevent insertions at ineditable locations if the insertion results from a user action (is interactive). Like gtk_text_buffer_insert(), but the insertion will not occur if want to prevent insertions at ineditable locations if the insertion results from a user action (is interactive). have a tag affecting editability applied to it. Typically the result of gtk_text_view_get_editable() is appropriate here. Parameters: Gtk.TextIter iter* Required (not null) a position in buffer String text Required (not null) some UTF-8 text gint32 len Required (not null) length of text in bytes, or -1 gboolean default_editable Required (not null) default editability of buffer Returns: gboolean whether text was actually inserted	Gtk.TextBuffer

Parameters: String text* Required (not null) text in UTF-8 format gint32 len Required (not null) length of text in bytes, or -1 gboolean default_editable Required (not null) default editability of buffer Returns: gboolean whether text was actually inserted	Gtk.TextBuffer
	insert_pixbuf (TextIter *iter, Pixbuf pixbuf) : none Inserts an image into the text buffer at iter. Inserts an image into the text buffer at iter. The image will be counted as one character in character counts, and when obtaining the buffer contents as a string, will be represented by the Unicode "object replacement character" 0xFFFC. Note that the "slice" variants for obtaining portions of the buffer as a string include this character for pixbufs, but the "text" variants do not. e.g. see gtk_text_buffer_get_slice() and gtk_text_buffer_get_text(). Parameters: Gtk.TextIter iter* Required (not null) location to insert the pixbuf GdkPixbuf.Pixbuf pixbuf Required (not null) a GdkPixbuf Returns: none	Gtk.TextBuffer
	insert_range (TextIter *iter, TextIter start, TextIter end) : none Copies text, tags, and pixbufs between start* and end (the order of start and end doesn't matter) and inserts the copy at iter. Copies text, tags, and pixbufs between start and end (the order of start and end doesn't matter) and inserts the copy at iter. Used instead of simply getting/inserting text because it preserves images and tags. If start and end are in a different buffer from Implemented via emissions of the insert_text and apply_tag signals, so expect those. Parameters: Gtk.TextIter iter Required (not null) a position in buffer Gtk.TextIter start Required (not null) a position in a GtkTextBuffer Gtk.TextIter end Required (not null) another position in the same buffer as start Returns: none	Gtk.TextBuffer

Same as gtk_text_buffer_insert_range(), but does nothing if the insertion point isn't editable. The default_editable* parameter indicates whether the text is editable at iter if no tags enclosing iter affect editability. Typically the result of gtk_text_view_get_editable() is appropriate here.
