Ancestors

Constructors

gtk_text_buffer_new

Creates a new text buffer.

Instance methods

gtk_text_buffer_add_mark

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.

since: 2.12

gtk_text_buffer_add_selection_clipboard

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.

gtk_text_buffer_apply_tag

Emits the “apply-tag” signal on buffer. The default handler for the signal applies tag to the given range. start and end do not have to be in order.

gtk_text_buffer_apply_tag_by_name

Calls gtk_text_tag_table_lookup() on the buffer’s tag table to get a GtkTextTag, then calls gtk_text_buffer_apply_tag().

gtk_text_buffer_backspace

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.

since: 2.6

gtk_text_buffer_begin_user_action

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.

gtk_text_buffer_copy_clipboard

Copies the currently-selected text to a clipboard.

gtk_text_buffer_create_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().

gtk_text_buffer_create_mark

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).

gtk_text_buffer_create_tag

Creates a tag and adds it to the tag table for buffer. Equivalent to calling gtk_text_tag_new() and then adding the tag to the buffer’s tag table. The returned tag is owned by the buffer’s tag table, so the ref count will be equal to one.

gtk_text_buffer_cut_clipboard

Copies the currently-selected text to a clipboard, then deletes said text if it’s editable.

gtk_text_buffer_delete

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.

gtk_text_buffer_delete_interactive

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.

gtk_text_buffer_delete_mark

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 GtkTextBuffer::mark-deleted signal will be emitted as notification after the mark is deleted.

gtk_text_buffer_delete_mark_by_name

Deletes the mark named name; the mark must exist. See gtk_text_buffer_delete_mark() for details.

gtk_text_buffer_delete_selection

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).

gtk_text_buffer_deserialize

This function deserializes rich text in format format and inserts it at iter.

since: 2.10

gtk_text_buffer_deserialize_get_can_create_tags

This functions returns the value set with gtk_text_buffer_deserialize_set_can_create_tags().

since: 2.10

gtk_text_buffer_deserialize_set_can_create_tags

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.

since: 2.10

gtk_text_buffer_end_user_action

Should be paired with a call to gtk_text_buffer_begin_user_action(). See that function for a full explanation.

gtk_text_buffer_get_bounds

Retrieves the first and last iterators in the buffer, i.e. the entire buffer lies within the range [start,end).

gtk_text_buffer_get_char_count

Gets the number of characters in the buffer; note that characters and bytes are not the same, you can’t e.g. expect the contents of the buffer in string form to be this many bytes long. The character count is cached, so this function is very fast.

gtk_text_buffer_get_copy_target_list

This function returns the list of targets this text buffer can provide for copying and as DND source. The targets in the list are added with info values from the GtkTextBufferTargetInfo enum, using gtk_target_list_add_rich_text_targets() and gtk_target_list_add_text_targets().

since: 2.10

gtk_text_buffer_get_deserialize_formats

This function returns the rich text deserialize formats registered with buffer using gtk_text_buffer_register_deserialize_format() or gtk_text_buffer_register_deserialize_tagset().

since: 2.10

gtk_text_buffer_get_end_iter

Initializes iter with the “end iterator,” one past the last valid character in the text buffer. If dereferenced with gtk_text_iter_get_char(), the end iterator has a character value of 0. The entire buffer lies in the range from the first position in the buffer (call gtk_text_buffer_get_start_iter() to get character position 0) to the end iterator.

gtk_text_buffer_get_has_selection

Indicates whether the buffer has some text currently selected.

since: 2.10

gtk_text_buffer_get_insert

Returns the mark that represents the cursor (insertion point). Equivalent to calling gtk_text_buffer_get_mark() to get the mark named “insert”, but very slightly more efficient, and involves less typing.

gtk_text_buffer_get_iter_at_child_anchor

Obtains the location of anchor within buffer.

gtk_text_buffer_get_iter_at_line

Initializes iter to the start of the given line. If line_number is greater than the number of lines in the buffer, the end iterator is returned.

gtk_text_buffer_get_iter_at_line_index

Obtains an iterator pointing to byte_index within the given line. byte_index must be the start of a UTF-8 character. Note bytes, not characters; UTF-8 may encode one character as multiple bytes.

gtk_text_buffer_get_iter_at_line_offset

Obtains an iterator pointing to char_offset within the given line. Note characters, not bytes; UTF-8 may encode one character as multiple bytes.

gtk_text_buffer_get_iter_at_mark

Initializes iter with the current position of mark.

gtk_text_buffer_get_iter_at_offset

Initializes iter to a position char_offset chars from the start of the entire buffer. If char_offset is -1 or greater than the number of characters in the buffer, iter is initialized to the end iterator, the iterator one past the last valid character in the buffer.

gtk_text_buffer_get_line_count

Obtains the number of lines in the buffer. This value is cached, so the function is very fast.

gtk_text_buffer_get_mark

Returns the mark named name in buffer buffer, or NULL if no such mark exists in the buffer.

gtk_text_buffer_get_modified

Indicates whether the buffer has been modified since the last call to gtk_text_buffer_set_modified() set the modification flag to FALSE. Used for example to enable a “save” function in a text editor.

gtk_text_buffer_get_paste_target_list

This function returns the list of targets this text buffer supports for pasting and as DND destination. The targets in the list are added with info values from the GtkTextBufferTargetInfo enum, using gtk_target_list_add_rich_text_targets() and gtk_target_list_add_text_targets().

since: 2.10

gtk_text_buffer_get_selection_bound

Returns the mark that represents the selection bound. Equivalent to calling gtk_text_buffer_get_mark() to get the mark named “selection_bound”, but very slightly more efficient, and involves less typing.

gtk_text_buffer_get_selection_bounds

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). start and end will be in ascending order. If start and end are NULL, then they are not filled in, but the return value still indicates whether text is selected.

gtk_text_buffer_get_serialize_formats

This function returns the rich text serialize formats registered with buffer using gtk_text_buffer_register_serialize_format() or gtk_text_buffer_register_serialize_tagset().

since: 2.10

gtk_text_buffer_get_slice

Returns the text in the range [start,end). Excludes undisplayed text (text marked with tags that set the invisibility attribute) if include_hidden_chars is FALSE. The returned string includes a 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.

gtk_text_buffer_get_start_iter

Initialized iter with the first position in the text buffer. This is the same as using gtk_text_buffer_get_iter_at_offset() to get the iter at character offset 0.

gtk_text_buffer_get_tag_table

Get the GtkTextTagTable associated with this buffer.

gtk_text_buffer_get_text

Returns the text in the range [start,end). Excludes undisplayed text (text marked with tags that set the invisibility attribute) if include_hidden_chars is FALSE. Does not include characters 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().

gtk_text_buffer_insert

Inserts len bytes of text at position iter. If len is -1, text must be nul-terminated and will be inserted in its 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.

gtk_text_buffer_insert_at_cursor

Simply calls gtk_text_buffer_insert(), using the current cursor position as the insertion point.

gtk_text_buffer_insert_child_anchor

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.

gtk_text_buffer_insert_interactive

Like gtk_text_buffer_insert(), but the insertion will not occur if iter is at a non-editable location in the buffer. Usually you want to prevent insertions at ineditable locations if the insertion results from a user action (is interactive).

gtk_text_buffer_insert_interactive_at_cursor

Calls gtk_text_buffer_insert_interactive() at the cursor position.

gtk_text_buffer_insert_markup

Inserts the text in markup at position iter. markup will be inserted in its entirety and must be nul-terminated and valid UTF-8. Emits the GtkTextBuffer::insert-text signal, possibly multiple times; insertion actually occurs in the default handler for the signal. iter will point to the end of the inserted text on return.

since: 3.16

gtk_text_buffer_insert_pixbuf

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().

gtk_text_buffer_insert_range

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 buffer, the two buffers must share the same tag table.

gtk_text_buffer_insert_range_interactive

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.

gtk_text_buffer_insert_with_tags

Inserts text into buffer at iter, applying the list of tags to the newly-inserted text. The last tag specified must be NULL to terminate the list. Equivalent to calling gtk_text_buffer_insert(), then gtk_text_buffer_apply_tag() on the inserted text; gtk_text_buffer_insert_with_tags() is just a convenience function.

gtk_text_buffer_insert_with_tags_by_name

Same as gtk_text_buffer_insert_with_tags(), but allows you to pass in tag names instead of tag objects.

gtk_text_buffer_move_mark

Moves mark to the new location where. Emits the GtkTextBuffer::mark-set signal as notification of the move.

gtk_text_buffer_move_mark_by_name

Moves the mark named name (which must exist) to location where. See gtk_text_buffer_move_mark() for details.

gtk_text_buffer_paste_clipboard

Pastes the contents of a clipboard. If override_location is NULL, the pasted text will be inserted at the cursor position, or the buffer selection will be replaced if the selection is non-empty.

gtk_text_buffer_place_cursor

This function moves the “insert” and “selection_bound” marks simultaneously. If you move them to the same place in two steps with gtk_text_buffer_move_mark(), you will temporarily select a region in between their old and new locations, which can be pretty inefficient since the temporarily-selected region will force stuff to be recalculated. This function moves them as a unit, which can be optimized.

gtk_text_buffer_register_deserialize_format

This function registers a rich text deserialization function along with its mime_type with the passed buffer.

since: 2.10

gtk_text_buffer_register_deserialize_tagset

This function registers GTK+’s internal rich text serialization format with the passed buffer. See gtk_text_buffer_register_serialize_tagset() for details.

since: 2.10

gtk_text_buffer_register_serialize_format

This function registers a rich text serialization function along with its mime_type with the passed buffer.

since: 2.10

gtk_text_buffer_register_serialize_tagset

This function registers GTK+’s internal rich text serialization format with the passed buffer. The internal format does not comply to any standard rich text format and only works between GtkTextBuffer instances. It is capable of serializing all of a text buffer’s tags and embedded pixbufs.

since: 2.10

gtk_text_buffer_remove_all_tags

Removes all tags in the range between start and end. Be careful with this function; it could remove tags added in code unrelated to the code you’re currently writing. That is, using this function is probably a bad idea if you have two or more unrelated code sections that add tags.

gtk_text_buffer_remove_selection_clipboard

Removes a GtkClipboard added with gtk_text_buffer_add_selection_clipboard().

gtk_text_buffer_remove_tag

Emits the “remove-tag” signal. The default handler for the signal removes all occurrences of tag from the given range. start and end don’t have to be in order.

gtk_text_buffer_remove_tag_by_name

Calls gtk_text_tag_table_lookup() on the buffer’s tag table to get a GtkTextTag, then calls gtk_text_buffer_remove_tag().

gtk_text_buffer_select_range

This function moves the “insert” and “selection_bound” marks simultaneously. If you move them in two steps with gtk_text_buffer_move_mark(), you will temporarily select a region in between their old and new locations, which can be pretty inefficient since the temporarily-selected region will force stuff to be recalculated. This function moves them as a unit, which can be optimized.

since: 2.4

gtk_text_buffer_serialize

This function serializes the portion of text between start and end in the rich text format represented by format.

since: 2.10

gtk_text_buffer_set_modified

Used to keep track of whether the buffer has been modified since the last time it was saved. Whenever the buffer is saved to disk, call gtk_text_buffer_set_modified (buffer, FALSE). When the buffer is modified, it will automatically toggled on the modified bit again. When the modified bit flips, the buffer emits the GtkTextBuffer::modified-changed signal.

gtk_text_buffer_set_text

Deletes current contents of buffer, and inserts text instead. If len is -1, text must be nul-terminated. text must be valid UTF-8.

gtk_text_buffer_unregister_deserialize_format

This function unregisters a rich text format that was previously registered using gtk_text_buffer_register_deserialize_format() or gtk_text_buffer_register_deserialize_tagset().

since: 2.10

gtk_text_buffer_unregister_serialize_format

This function unregisters a rich text format that was previously registered using gtk_text_buffer_register_serialize_format() or gtk_text_buffer_register_serialize_tagset().

since: 2.10

Virtual methods

Gtk.TextBufferClass.apply_tag

Emits the “apply-tag” signal on buffer. The default handler for the signal applies tag to the given range. start and end do not have to be in order.

Gtk.TextBufferClass.begin_user_action

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.

Gtk.TextBufferClass.changed

The class handler for the GtkTextBuffer::changed signal.

Gtk.TextBufferClass.delete_range

The class handler for the GtkTextBuffer::delete-range signal.

Gtk.TextBufferClass.end_user_action

Should be paired with a call to gtk_text_buffer_begin_user_action(). See that function for a full explanation.

Gtk.TextBufferClass.insert_child_anchor

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.

Gtk.TextBufferClass.insert_pixbuf

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().

Gtk.TextBufferClass.insert_text

The class handler for the GtkTextBuffer::insert-text signal.

Gtk.TextBufferClass.mark_deleted

The class handler for the GtkTextBuffer::mark-deleted signal.

Gtk.TextBufferClass.mark_set

The class handler for the GtkTextBuffer::mark-set signal.

Gtk.TextBufferClass.modified_changed

The class handler for the GtkTextBuffer::modified-changed signal.

Gtk.TextBufferClass.paste_done

The class handler for the GtkTextBuffer::paste-done signal.

Gtk.TextBufferClass.remove_tag

Emits the “remove-tag” signal. The default handler for the signal removes all occurrences of tag from the given range. start and end don’t have to be in order.
