## Detailed Description

Gutter object for View.

The Gutter object represents the left and right gutters of the text view. It is used by View to draw the line numbers and category marks that might be present on a line. By packing additional CellRenderer objects in the gutter, you can extend the gutter with your own custom drawings.

The gutter works very much the same way as cells rendered in a Gtk::TreeView. The concept is similar, with the exception that the gutter does not have an underlying Gtk::TreeModel. Instead, you should use set_cell_data_func() to set a callback to fill in any of the cell renderers properties, given the line for which the cell is to be rendered. Renderers are inserted into the gutter at a certain position. The builtin line number renderer is at position View::gutter_position_lines (-30) and the marks renderer is at View::gutter_position_marks (-20). You can use these values to position custom renderers accordingly. The width of a cell renderer can be specified as either fixed (using Gtk::CellRenderer::set_fixed_size()) or dynamic, in which case you must set set_cell_size_func(). This callback is used to set the properties of the renderer such that Gtk::CellRenderer::get_size() yields the maximum width of the cell.

## Member Function Documentation

void Gsv::Gutter::get_padding | ( | int & | xpad,
|  | int & | ypad
| ) |  | const

GutterRenderer* Gsv::Gutter::get_renderer_at_pos | ( | int | x,
|  | int | y
| ) |  |

Finds the Gtk::SourceGutterRenderer at (x, y).

Parameters

  x | The x position to get identified.
  y | The y position to get identified.

Returns
  The renderer at (x, y) or `0`.

const GutterRenderer* Gsv::Gutter::get_renderer_at_pos | ( | int | x,
|  | int | y
| ) |  | const

Finds the Gtk::SourceGutterRenderer at (x, y).

Parameters

  x | The x position to get identified.
  y | The y position to get identified.

Returns
  The renderer at (x, y) or `0`.

static GType Gsv::Gutter::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

Glib::RefPtr<Gdk::Window> Gsv::Gutter::get_window | ( |  | ) |

Get the Gdk::Window of the gutter.

The window will only be available when the gutter has at least one, non-zero width, cell renderer packed.

Returns
  The Gdk::Window of the gutter, or empty Glib::RefPtr if the gutter has no window.

Since gtksourceviewmm 2.10:

Glib::RefPtr<const Gdk::Window> Gsv::Gutter::get_window | ( |  | ) | const

Get the Gdk::Window of the gutter.

The window will only be available when the gutter has at least one, non-zero width, cell renderer packed.

Returns
  The Gdk::Window of the gutter, or empty Glib::RefPtr if the gutter has no window.

Since gtksourceviewmm 2.10:

GtkSourceGutter* Gsv::Gutter::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

const GtkSourceGutter* Gsv::Gutter::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

GtkSourceGutter* Gsv::Gutter::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

void Gsv::Gutter::insert | ( | GutterRenderer* | renderer,
|  | int | position
| ) |  |

Insert renderer into the gutter.

If renderer is yet unowned then gutter claims its ownership. Otherwise just increases renderer's reference count. renderer cannot be already inserted to another gutter.

Since gtksourceviewmm 3.0:

Parameters

  renderer | A gutter renderer (must inherit from Gtk::SourceGutterRenderer).
  position | The renderer position.

Returns
  `true` if operation succeeded. Otherwise `false`.

Gutter& Gsv::Gutter::operator= | ( | Gutter&& | src | ) |
| noexcept

Glib::PropertyProxy_ReadOnly< View* > Gsv::Gutter::property_view | ( |  | ) | const

The gutters' GtkSourceView.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< Gtk::TextWindowType > Gsv::Gutter::property_window_type | ( |  | ) | const

The gutters text window type.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy< int > Gsv::Gutter::property_xpad | ( |  | ) |

The x-padding.

Deprecated:
  Use GutterRenderer's xpad property instead.

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< int > Gsv::Gutter::property_xpad | ( |  | ) | const

The x-padding.

Deprecated:
  Use GutterRenderer's xpad property instead.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy< int > Gsv::Gutter::property_ypad | ( |  | ) |

The y-padding.

Deprecated:
  Use GutterRenderer's ypad property instead.

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< int > Gsv::Gutter::property_ypad | ( |  | ) | const

The y-padding.

Deprecated:
  Use GutterRenderer's ypad property instead.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

void Gsv::Gutter::queue_draw | ( |  | ) |

Invalidates the drawable area of the gutter.

You can use this to force a redraw of the gutter if something has changed and needs to be redrawn.

Since gtksourceviewmm 2.8:

void Gsv::Gutter::remove | ( | GutterRenderer* | renderer | ) |

Removes renderer from gutter.

Since gtksourceviewmm 2.8:

Parameters

  renderer | A Gtk::SourceGutterRenderer.

void Gsv::Gutter::reorder | ( | GutterRenderer* | renderer,
|  | int | position
| ) |  |

Reorders renderer in gutter to new position.

Since gtksourceviewmm 2.8:

Parameters

  renderer | A Gtk::CellRenderer.
  position | The new renderer position.

void Gsv::Gutter::set_padding | ( | int | xpad,
|  | int | ypad
| ) |  |
