gtksourceview2.Buffer.backward_iter_to_source_mark

    def backward_iter_to_source_mark(iter, category=None)

The backward_iter_to_source_mark() method moves iter to the position of the previous gtksourceview2.Mark of the given category. Returns True if iter was moved. If category is None, the previous source mark can be of any category.

gtksourceview2.Buffer.begin_not_undoable_action

    def begin_not_undoable_action()

The begin_not_undoable_action() marks the beginning of a not undoable action on the buffer, disabling the undo manager. Typically you would call this function before initially setting the contents of the buffer (e.g. when loading a file in a text editor).

You may nest begin_not_undoable_action() / end_not_undoable_action() blocks.

gtksourceview2.Buffer.can_redo

    def can_redo()

The can_redo() method Determines whether a source buffer can redo the last action (i.e. if the last operation was an undo).

gtksourceview2.Buffer.can_undo

    def can_undo()

The can_undo() method determines whether a source buffer can undo the last action.

gtksourceview2.Buffer.create_source_mark

    def create_source_mark(name, category, where)

The create_source_mark() method creates a mark in the gtksourceview2.Buffer of category category. A mark is semantically very similar to a gtk.TextMark, but organised into categories.

Like a gtk.TextMark, a gtksourceview2.Mark can be anonymous if the passed name is None.

Like a gtk.TextMark, a gtksourceview2.Marker can be anonymous if the passed name is None. Also, the buffer owns the markers so you shouldn't unreference it.

Marks always have left gravity and are moved to the beginning of the line when the user deletes the line they were in. Also, if the user deletes a region of text which contained lines with markers, those are deleted.

Typical uses for marks are bookmarks, breakpoints, current executing instruction indication in a source file, etc..

gtksourceview2.Buffer.end_not_undoable_action

    def end_not_undoable_action()

The end_not_undoable_action() method marks the end of a not undoable action on the buffer. When the last not undoable block is closed through the call to this function, the list of undo actions is cleared and the undo manager is re-enabled.

gtksourceview2.Buffer.ensure_highlight

    def ensure_highlight(start, end)

The ensure_highlight() method forces buffer to analyze and highlight the given area synchronously.

gtksourceview2.Buffer.forward_iter_to_source_mark

    def forward_iter_to_source_mark(iter, category=None)

The forward_iter_to_source_mark() method moves iter to the position of the next gtksourceview2.Mark of the given category. Returns True if iter was moved. If category is None, the previous source mark can be of any category.

gtksourceview2.Buffer.get_highlight_matching_brackets

    def get_highlight_matching_brackets()

The get_highlight_matching_brackets() method determines whether bracket match highlighting is activated for the source buffer.

gtksourceview2.Buffer.get_highlight_syntax

    def get_highlight_syntax()

The get_highlight_syntax() method determines whether syntax highlighting is activated in the source buffer.

gtksourceview2.Buffer.get_language

    def get_language()

The get_language() method returns the gtksourceview2.Language associated with the buffer, see gtksourceview2.Buffer.set_language().

gtksourceview2.Buffer.get_source_marks_at_iter

    def get_source_marks_at_iter(iter, category=None)

The get_source_marks_at_iter() method returns the list of marks of the given category at iter. If category is None it returns all marks at iter.

gtksourceview2.Buffer.get_source_marks_at_line

    def get_source_marks_at_line(iter, category=None)

The get_source_marks_at_line() method returns the list of marks of the given category at line. If category is None it returns all marks at line.

gtksourceview2.Buffer.get_max_undo_levels

    def get_max_undo_levels()

The get_max_undo_levels() method determines the number of undo levels the buffer will track for buffer edits.

gtksourceview2.Buffer.get_style_scheme

    def get_style_scheme()

The get_style_scheme() method returns the nearest marker to the right of iter. If there are multiple markers at the same position, this function will always return the first one (from the internal linked list), even if starting the search exactly at its location. You can get the others using gtksourceview2.Marker.next().

gtksourceview2.Buffer.redo

    def redo()

The redo() method redoes the last undo operation. Use gtksourceview2.Buffer.can_redo to check whether a call to this function will have any effect.

gtksourceview2.Buffer.remove_source_marks

    def remove_source_marks(start, end, category=None)

The remove_source_marks() method remove all marks of category between start and end from the buffer. If category is None, all marks in the range will be removed.

gtksourceview2.Buffer.set_highlight_matching_brackets

    def set_highlight_matching_brackets(highlight)

The set_highlight_matching_brackets() method Controls the bracket match highlighting function in the buffer. If activated, when you position your ursor over a bracket character (a parenthesis, a square bracket, etc.) the matching opening or closing bracket character will be highlighted.

gtksourceview2.Buffer.set_highlight_syntax

    def set_highlight_syntax(highlight)

The set_highlight_syntax() method controls whether syntax is highlighted in the buffer. If highlight is True, the text will be highlighted according to the syntax patterns specified in the language set with gtksourceview2.Buffer.set_language(). If highlight is False, syntax highlighting is disabled and all the GtkTextTag objects that have been added by the syntax highlighting engine are removed from the buffer.

gtksourceview2.Buffer.set_language

    def set_language(language)

The set_language() method associate a gtksourceview2.Language with the source buffer. If language is not-None and syntax highlighting is enabled (see gtksourceview2.Buffer.set_highlight_syntax()), the syntax patterns defined in language will be used to highlight the text contained in the buffer. If language is None, the text contained in the buffer is not highlighted.

gtksourceview2.Buffer.set_max_undo_levels

    def set_max_undo_levels(max_undo_levels)

The set_max_undo_levels() method sets the number of undo levels for user actions the buffer will track. If the number of user actions exceeds the limit set by this function, older actions will be discarded.

If max_undo_levels is -1, no limit is set.

A new action is started whenever the function gtk.TextBuffer.begin_user_action is called. In general, this happens whenever the user presses any key which modifies the buffer, but the undo manager will try to merge similar consecutive actions, such as multiple character insertions into one action. But, inserting a newline does start a new action.

gtksourceview2.Buffer.set_style_scheme

    def set_style_scheme(scheme)

The set_style_scheme() method sets the style scheme used by the buffer.

gtksourceview2.Buffer.undo

    def undo()

The undo() Undoes the last user action which modified the buffer. Use gtksourceview2.Buffer.can_undo to check whether a call to this function will have any effect.

Actions are defined as groups of operations between a call to gtk.TextBuffer.begin_user_action() and gtk.TextBuffer.end_user_action(), or sequences of similar edits (inserts or deletes) on the same line.

The "highlight-updated" gtksourceview2.Buffer Signal

    def callback(sourcebuffer, start, end, user_param1, ...)

The "highlight-updated" signal is emitted whenever the syntax highlighting information has been updated, so that views can request a redraw if the region changed is visible. Usually only view widgets displaying this buffer will be interested in this signal.

The "marker-updated" gtksourceview2.Buffer Signal

    def callback(sourcebuffer, arg1, user_param1, ...)

The "source-mark-updated" signal is emitted whenever a mark is added to, moved or removed from the buffer.

gtksourceview2.iter_backward_search

    def gtksourceview2.iter_backward_search(iter, str, flags, limit)

The iter_backward_search() function is the same as the gtksourceview2.iter_forward_search() function, except searches backward.

gtksourceview2.iter_forward_search

    def gtksourceview2.iter_forward_search(iter, str, flags, limit)

The iter_forward_search() function searches forward for str and returns a tuple containing gtk.TextIter objects that point at the start and end locations of the match. The search will not continue past limit. Note that a search is a linear or O(n) operation, so you may wish to use limit to avoid locking up your UI on large buffers.

If the gtksourceview2.SOURCE_SEARCH_VISIBLE_ONLY flag is present, the match may have invisible text interspersed in str. i.e. str will be a possibly-noncontiguous subsequence of the matched range. similarly, if you specify gtksourceview2.SOURCE_SEARCH_TEXT_ONLY, the match may have pixbufs or child widgets mixed inside the matched range. If these flags are not given, the match must be exact; the special 0xFFFC character in str will match embedded pixbufs or child widgets. If you specify the gtksourceview2.SOURCE_SEARCH_CASE_INSENSITIVE flag, the text will be matched regardless of what case it is in.

Same as gtk.TextIter.forward_search(), but supports case insensitive searching.
