## Detailed Description

An interface for packing cells.

CellLayout is an interface to be implemented by all objects which want to provide a TreeView::Column-like API for packing cells, setting attributes and data funcs.

## Member Typedef Documentation

typedef sigc::slot<void, const TreeModel::const_iterator&> Gtk::CellLayout::SlotCellData

## Constructor & Destructor Documentation

Gtk::CellLayout::CellLayout | ( |  | ) |

protected

You should derive from this class to use it.

## Member Function Documentation

void Gtk::CellLayout::add_attribute | ( | CellRenderer& | cell,
|  | const Glib::ustring & | attribute,
|  | int | column
| ) |  |

Adds an attribute mapping to the list in cell_layout.

The column is the column of the model to get a value from, and the attribute is the parameter on cell to be set from the value. So for example if column 2 of the model contains strings, you could have the “text” attribute of a Gtk::CellRendererText get its values from column 2.

Since gtkmm 2.4:

Parameters

  cell | A Gtk::CellRenderer.
  attribute | An attribute on the renderer.
  column | The column position on the model to get the attribute from.

void Gtk::CellLayout::add_attribute | ( | const Glib::PropertyProxy_Base & | property,
|  | const TreeModelColumnBase& | column
| ) |  |

void Gtk::CellLayout::add_attribute | ( | CellRenderer& | cell,
|  | const Glib::ustring & | attribute,
|  | const TreeModelColumnBase& | column
| ) |  |

virtual void Gtk::CellLayout::add_attribute_vfunc | ( | CellRenderer* | cell,

static void Gtk::CellLayout::add_interface | ( | GType | gtype_implementer | ) |

static

void Gtk::CellLayout::clear | ( |  | ) |

Unsets all the mappings on all renderers on cell_layout and removes all renderers from cell_layout.

Since gtkmm 2.4:

void Gtk::CellLayout::clear_attributes | ( | CellRenderer& | cell | ) |

Clears all existing attributes previously set with set_attributes().

Since gtkmm 2.4:

Parameters

  cell | A Gtk::CellRenderer to clear the attribute mapping on.

virtual void Gtk::CellLayout::clear_attributes_vfunc | ( | CellRenderer* | cell | ) |

protected virtual

virtual void Gtk::CellLayout::clear_vfunc | ( |  | ) |

protected virtual

Glib::RefPtr<CellArea> Gtk::CellLayout::get_area | ( |  | ) |

Returns the underlying Gtk::CellArea which might be cell_layout if called on a Gtk::CellArea or might be `0` if no Gtk::CellArea is used by cell_layout.

Since gtkmm 3.0:

Returns
  The cell area used by cell_layout.

Glib::RefPtr<const CellArea> Gtk::CellLayout::get_area | ( |  | ) | const

Returns the underlying Gtk::CellArea which might be cell_layout if called on a Gtk::CellArea or might be `0` if no Gtk::CellArea is used by cell_layout.

Since gtkmm 3.0:

Returns
  The cell area used by cell_layout.

std::vector<CellRenderer*> Gtk::CellLayout::get_cells | ( |  | ) |

Return value: a list of cell renderers.

Since gtkmm 2.12:

Returns
  A list of cell renderers.

std::vector<const CellRenderer*> Gtk::CellLayout::get_cells | ( |  | ) | const

Return value: a list of cell renderers.

Since gtkmm 2.12:

Returns
  A list of cell renderers.

CellRenderer* Gtk::CellLayout::get_first_cell | ( |  | ) |

Gets the CellRenderer for the column.

You should dynamic_cast<> to the expected derived CellRenderer type. This assumes that the CellLayout contains only one CellRenderer.

const CellRenderer* Gtk::CellLayout::get_first_cell | ( |  | ) | const

Gets the CellRenderer for the column.

You should dynamic_cast<> to the expected derived CellRenderer type. This assumes that the CellLayout contains only one CellRenderer.

static GType Gtk::CellLayout::get_type | ( |  | ) |

static

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

GtkCellLayout* Gtk::CellLayout::gobj | ( |  | ) |

inline

Provides access to the underlying C GObject.

const GtkCellLayout* Gtk::CellLayout::gobj | ( |  | ) | const

inline

Provides access to the underlying C GObject.

void Gtk::CellLayout::pack_end | ( | CellRenderer& | cell,
|  | bool | expand = `true`
| ) |  |

Adds the cell to the end of cell_layout.

If expand is `false`, then the cell is allocated no more space than it needs. Any unused space is divided evenly between cells for which expand is `true`.

Note that reusing the same cell renderer is not supported.

Since gtkmm 2.4:

Parameters

  cell | A Gtk::CellRenderer.
  expand | `true` if cell is to be given extra space allocated to cell_layout.

virtual void Gtk::CellLayout::pack_end_vfunc | ( | CellRenderer* | cell,
|  | bool | expand
| ) |  |

protected virtual

template <class ColumnType >

void Gtk::CellLayout::pack_start | ( | const TreeModelColumn< ColumnType >& | model_column,
|  | bool | expand = `true`
| ) |  |

inline

void Gtk::CellLayout::pack_start | ( | CellRenderer& | cell,
|  | bool | expand = `true`
| ) |  |

Packs the cell into the beginning of cell_layout.

If expand is `false`, then the cell is allocated no more space than it needs. Any unused space is divided evenly between cells for which expand is `true`.

Note that reusing the same cell renderer is not supported.

Since gtkmm 2.4:

Parameters

  cell | A Gtk::CellRenderer.
  expand | `true` if cell is to be given extra space allocated to cell_layout.

template <class T_ModelColumnType >

void Gtk::CellLayout::pack_start | ( | const TreeModelColumn< T_ModelColumnType >& | column,
|  | bool | expand
| ) |  |

virtual void Gtk::CellLayout::pack_start_vfunc | ( | CellRenderer* | cell,
|  | bool | expand
| ) |  |

protected virtual

void Gtk::CellLayout::reorder | ( | CellRenderer& | cell,
|  | int | position
| ) |  |

Re-inserts cell at position.

Note that cell has already to be packed into cell_layout for this to function properly.

Since gtkmm 2.4:

Parameters

  cell | A Gtk::CellRenderer to reorder.
  position | New position to insert cell at.

virtual void Gtk::CellLayout::reorder_vfunc | ( | CellRenderer* | cell,
|  | int | position
| ) |  |
