The Buffer class is the model for View widgets. It extends the Gtk::TextBuffer class by adding features useful to display and edit source code as syntax highlighting and bracket matching. It also implements support for undo/redo operations.
To create a Buffer use Buffer::create(). A convenience overload for initial setting a Language is also provided.
By default highlighting is enabled, but you can disable it with Buffer::set_highlight_syntax().

bool Gsv::Buffer::backward_iter_to_source_mark | ( | Gtk::TextIter & | iter, |
const Glib::ustring & | category | ||
) |
Moves iter to the position of the previous Mark of the given category.
iter | An iterator. |
category | Category to search. |
true
if iter was moved. bool Gsv::Buffer::backward_iter_to_source_mark | ( | Gtk::TextIter & | iter | ) |
Moves iter to the position of the previous Mark of any category.
iter | An iterator. |
true
if iter was moved. void Gsv::Buffer::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.
bool Gsv::Buffer::can_redo | ( | ) | const |
Determines whether a source buffer can redo the last action (i.e. if the last operation was an undo).
true
if a redo is possible. bool Gsv::Buffer::can_undo | ( | ) | const |
Determines whether a source buffer can undo the last action.
true
if it's possible to undo the last action.
|

const Glib::ustring & | category, | ||
const Gtk::TextIter & | where | ||
) |
Creates a source mark in the buffer of category category.
A source mark is a Gtk::TextMark but organised into categories. Depending on the category a pixbuf can be specified that will be displayed along the line of the mark.
Marks always have left gravity and are moved to the beginning of the line when the user deletes the line they were in.
Typical uses for a source mark are bookmarks, breakpoints, current executing instruction indication in a source file, etc.

category | A string defining the mark category. |

The buffer undo manager.
void Gsv::Buffer::redo | ( | ) |
Redoes the last undo operation.
Use can_redo() to check whether a call to this function will have any effect.
This function emits the Gtk::SourceBuffer::signal_redo() signal.
void Gsv::Buffer::remove_source_marks | ( | const Gtk::TextIter & | start, |
const Gtk::TextIter & | end, | ||
const Glib::ustring & | category | ||

void Gsv::Buffer::set_default_undo_manager | ( | ) |
Set the default buffer undo manager.
void Gsv::Buffer::set_highlight_matching_brackets | ( | bool | highlight = true | ) |
Controls the bracket match highlighting function in the buffer.
If activated, when you position your cursor over a bracket character (a parenthesis, a square bracket, etc.) the matching opening or closing bracket character will be highlighted.
highlight | true if you want matching brackets highlighted. |
void Gsv::Buffer::set_highlight_syntax | ( | bool | highlight = true | ) |
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 set_language(). If highlight is false
, syntax highlighting is disabled and all the Gtk::TextTag objects that have been added by the syntax highlighting engine are removed from the buffer.
highlight | true to enable syntax highlighting, false to disable it. |
void Gsv::Buffer::set_implicit_trailing_newline | ( | bool | implicit_trailing_newline = true | ) |
Sets whether the buffer has an implicit trailing newline.
If an explicit trailing newline is present in a GtkTextBuffer, GtkTextView shows it as an empty line. This is generally not what the user expects. If implicit_trailing_newline is TRUE (the default value):
implicit_trailing_newline | the new value. |
void Gsv::Buffer::set_language | ( | const Glib::RefPtr< Language >& | language | ) |
Associate a Language with the source buffer.
If language is not empty and syntax highlighting is enabled, the syntax patterns defined in language will be used to highlight the text contained in the buffer. If language is empty, the text contained in the buffer is not highlighted.
The buffer holds a reference to language.
language | A Language to set, or empty Glib::RefPtr. |
void Gsv::Buffer::set_max_undo_levels | ( | int | max_undo_levels = true | ) |
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 method 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.
max_undo_levels | The desired maximum number of undo levels. |
void Gsv::Buffer::set_style_scheme | ( | const Glib::RefPtr< StyleScheme >& | scheme | ) |
Sets style scheme used by the buffer.
If scheme is empty no style scheme is used.
scheme | Style scheme. |

Glib::SignalProxy< void,Gtk::TextIter&,BracketMatchType > Gsv::Buffer::signal_bracket_matched | ( | ) |
Sets iter to a valid iterator pointing to the matching bracket if state is BracketMatchType::BRACKET_MATCH_FOUND.
void on_my_bracket_matched(Gtk::TextIter& iter, BracketMatchType state)
Flags: Run Last
iter is set to a valid iterator pointing to the matching bracket if state is Gtk::SOURCE_BRACKET_MATCH_FOUND. Otherwise iter is meaningless.
The signal is emitted only when the state changes, typically when the cursor moves.
A use-case for this signal is to show messages in a Gtk::Statusbar.
iter | If found, the location of the matching bracket. |
state | State of bracket matching. |
Glib::SignalProxy< void,Gtk::TextIter&,Gtk::TextIter& > Gsv::Buffer::signal_highlight_updated | ( | ) |
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.
void on_my_highlight_updated(Gtk::TextIter& start, Gtk::TextIter& end)
Flags: Run Last
The signal_highlight_updated() signal is emitted when the syntax highlighting and [context classes][context-classes] are updated in a certain region of the buffer.
start | The start of the updated region. |
end | The end of the updated region. |
Glib::SignalProxy< void > Gsv::Buffer::signal_redo | ( | ) |
Emitted whenever redo is requested.
In fact, it is emitted when redo() is called.
void on_my_redo()
Flags: Run Last
The signal_redo() signal is emitted to redo the last undo operation.
Glib::SignalProxy< void,const Glib::RefPtr<Gtk::TextMark>& > Gsv::Buffer::signal_source_mark_updated | ( | ) |
Emitted whenever a marker of sourcebuffer has changed and needs to be redisplayed by the view.
A change in a marker's type or location can trigger this signal. Note that moving a marker causes the emission of this signal twice: one for the old location and one for the new.
void on_my_source_mark_updated(const Glib::RefPtr<Gtk::TextMark>& where)
Flags: Run Last
The signal_source_mark_updated() signal is emitted each time a mark is added to, moved or removed from the buffer.
where | The Gtk::SourceMark. |
Glib::SignalProxy< void > Gsv::Buffer::signal_undo | ( | ) |
Emitted whenever undo is requested.
In fact, it is emitted when undo() is called.
void on_my_undo()
Flags: Run Last
The signal_undo() signal is emitted to undo the last user action which modified the buffer.
void Gsv::Buffer::undo | ( | ) |
Undoes the last user action which modified the buffer.
Use 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.
void Gsv::Buffer::unset_style_scheme | ( | ) |
Unsets style scheme used by the buffer.
It is the same like calling set_style_scheme() with empty pointer.
