## Detailed Description

Typedefed as Gtk::TreeView::Column.

This is a visible column in a Gtk::TreeView widget. It determines the geometry, type.

## Member Typedef Documentation

typedef TreeViewColumn Gtk::TreeViewColumn::Column

typedef sigc::slot<void(CellRenderer*, const Gtk::TreeModel::const_iterator&)> Gtk::TreeViewColumn::SlotTreeCellData

For instance, void on_cell_data(Gtk::CellRenderer* cell, const Gtk::TreeModel::iterator& iter);.

This function is used instead of the standard attributes mapping for setting the column value, and should set the value of the column's cell renderer as appropriate.

template <class T_ModelColumnType >

Gtk::TreeViewColumn::TreeViewColumn | ( | const Glib::ustring & | title,
|  | const TreeModelColumn< T_ModelColumnType >& | column
| ) |  |

Create a default view column for the given model column type.

## Member Function Documentation

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

Adds an attribute mapping to the list in tree_column.

The column is the column of the model to get a value from, and the attribute is the parameter on cell_renderer 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.

Parameters

  cell_renderer | The Gtk::CellRenderer to set attributes on.
  attribute | An attribute on the renderer.
  column | The column position on the model to get the attribute from.

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

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

void Gtk::TreeViewColumn::cell_get_size | ( | const Gdk::Rectangle& | cell_area,
|  | int & | x_offset,
|  | int & | y_offset,
|  | int & | width,
|  | int & | height
| ) |  | const

Obtains the width and height needed to render the column.

This is used primarily by the Gtk::TreeView.

Parameters

  cell_area | The area a cell in the column will be allocated.
  x_offset | Location to return x offset of a cell relative to cell_area.
  y_offset | Location to return y offset of a cell relative to cell_area.
  width | Location to return width needed to render a cell.
  height | Location to return height needed to render a cell.

bool Gtk::TreeViewColumn::cell_is_visible | ( |  | ) | const

Returns `true` if any of the cells packed into the tree_column are visible.

For this to be meaningful, you must first initialize the cells with cell_set_cell_data()

Returns
  `true`, if any of the cells packed into the tree_column are currently visible.

void Gtk::TreeViewColumn::cell_set_cell_data | ( | const Glib::RefPtr< TreeModel >& | tree_model,
|  | const TreeModel::iterator& | iter,
|  | bool | is_expander,
|  | bool | is_expanded
| ) |  |

Sets the cell renderer based on the tree_model and iter.

That is, for every attribute mapping in tree_column, it will get a value from the set column on the iter, and use that value to set the attribute on the cell renderer. This is used primarily by the Gtk::TreeView.

Parameters

  tree_model | The Gtk::TreeModel to to get the cell renderers attributes from.
  iter | The Gtk::TreeIter to to get the cell renderer’s attributes from.
  is_expander | `true`, if the row has children.
  is_expanded | `true`, if the row has visible children.

void Gtk::TreeViewColumn::clear | ( |  | ) |

Unsets all the mappings on all renderers on the tree_column.

void Gtk::TreeViewColumn::clear_attributes | ( | CellRenderer& | cell_renderer | ) |

Clears all existing attributes previously set with set_attributes().

Parameters

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

void Gtk::TreeViewColumn::clicked | ( |  | ) |

Emits the “clicked” signal on the column.

This function will only work if tree_column is clickable.

void Gtk::TreeViewColumn::focus_cell | ( | CellRenderer& | cell | ) |

Sets the current keyboard focus to be at cell, if the column contains 2 or more editable and activatable cells.

Parameters

  cell | A Gtk::CellRenderer.

float Gtk::TreeViewColumn::get_alignment | ( |  | ) | const

Returns the current x alignment of tree_column.

This value can range between 0.0 and 1.0.

Returns
  The current alignent of tree_column.

Returns the button used in the treeview column header.

Returns
  The button for the column header.

const Button* Gtk::TreeViewColumn::get_button | ( |  | ) | const

Returns the button used in the treeview column header.

Returns

bool Gtk::TreeViewColumn::get_cell_position | ( | const CellRenderer& | cell_renderer,
|  | int & | start_pos,
|  | int & | width
| ) |  | const

Obtains the horizontal position and size of a cell in a column.

If the cell is not found in the column, start_pos and width are not changed and `false` is returned.

void Gtk::TreeViewColumn::set_cell_data_func | ( | CellRenderer& | cell_renderer,
|  | const SlotTreeCellData& | slot
| ) |  |

Sets the slot callback to use for the column.

This callback function is used instead of the standard attributes mapping for setting the column value, and should set the value of the column's cell renderer as appropriate.

See also unset_cell_data_func().

Parameters

  cell_renderer | A Gtk::CellRenderer
  slot | The callback slot to use. Create this with sigc::mem_fun(), or sigc::ptr_fun().

void Gtk::TreeViewColumn::set_clickable | ( | bool | clickable = `true` | ) |

Sets the header to be active if clickable is `true`.

When the header is active, then it can take keyboard focus, and can be clicked.

Parameters

  clickable | `true` if the header is active.

void Gtk::TreeViewColumn::set_expand | ( | bool | expand = `true` | ) |

Sets the column to take available extra space.

This space is shared equally amongst all columns that have the expand set to `true`. If no column has this option set, then the last column gets all extra space. By default, every column is created with this `false`.

Along with “fixed-width”, the “expand” property changes when the column is resized by the user.

Parameters

  expand | `true` if the column should expand to fill available space.

void Gtk::TreeViewColumn::set_fixed_width | ( | int | fixed_width | ) |

If fixed_width is not -1, sets the fixed width of tree_column; otherwise unsets it.

The effective value of fixed_width is clamped between the minimum and maximum width of the column; however, the value stored in the “fixed-width” property is not clamped. If the column sizing is Gtk::TreeViewColumn::Sizing::GROW_ONLY or Gtk::TreeViewColumn::Sizing::AUTOSIZE, setting a fixed width overrides the automatically calculated width. Note that fixed_width is only a hint to GTK+; the width actually allocated to the column may be greater or less than requested.

Along with “expand”, the “fixed-width” property changes when the column is resized by the user.

Parameters

  fixed_width | The new fixed width, in pixels, or -1.

void Gtk::TreeViewColumn::set_max_width | ( | int | max_width | ) |

Sets the maximum width of the tree_column.

If max_width is -1, then the maximum width is unset. Note, the column can actually be wider than max width if it’s the last column in a view. In this case, the column expands to fill any extra space.

Parameters

  max_width | The maximum width of the column in pixels, or -1.

void Gtk::TreeViewColumn::set_min_width | ( | int | min_width | ) |

Sets the minimum width of the tree_column.

If min_width is -1, then the minimum width is unset.

Parameters

  min_width | The minimum width of the column in pixels, or -1.

void Gtk::TreeViewColumn::set_renderer | ( | Gtk::CellRenderer& | renderer,
|  | const TreeModelColumnBase& | column
| ) |  |

Associate a view CellRenderer with a model column, so that the CellRenderer renders the data in the model column.

Parameters

  renderer | The view cell renderer which will render the model column.
  column | The model column to be renderered by this view.

void Gtk::TreeViewColumn::set_reorderable | ( | bool | reorderable = `true` | ) |

If reorderable is `true`, then the column can be reordered by the end user dragging the header.

Parameters

  reorderable | `true`, if the column can be reordered.

void Gtk::TreeViewColumn::set_resizable | ( | bool | resizable = `true` | ) |

If resizable is `true`, then the user can explicitly resize the column by grabbing the outer edge of the column button.

If resizable is `true` and sizing mode of the column is Gtk::TreeViewColumn::Sizing::AUTOSIZE, then the sizing mode is changed to Gtk::TreeViewColumn::Sizing::GROW_ONLY.

Parameters

  resizable | `true`, if the column can be resized.

void Gtk::TreeViewColumn::set_sizing | ( | Sizing | type | ) |

Sets the growth behavior of tree_column to type.

void Gtk::TreeViewColumn::set_sort_column | ( | const TreeModelColumnBase& | sort_column_id | ) |

Sets the logical sort_column_id that this column sorts on when this column is selected for sorting.

Doing so makes the column header clickable.

Parameters

  sort_column_id | The sort_column_id of the model to sort on.

void Gtk::TreeViewColumn::set_sort_column | ( | int | sort_column_id | ) |

Sets the logical sort_column_id that this column sorts on when this column is selected for sorting.

Doing so makes the column header clickable.

Parameters

  sort_column_id | The sort_column_id of the model to sort on.

void Gtk::TreeViewColumn::set_sort_indicator | ( | bool | setting | ) |

Call this function with a setting of `true` to display an arrow in the header button indicating the column is sorted.

Call set_sort_order() to change the direction of the arrow.

Parameters

  setting | `true` to display an indicator that the column is sorted.

void Gtk::TreeViewColumn::set_sort_order | ( | SortType | order | ) |

Changes the appearance of the sort indicator.

This does not actually sort the model. Use set_sort_column_id() if you want automatic sorting support. This function is primarily for custom sorting behavior, and should be used in conjunction with Gtk::TreeSortable::set_sort_column_id() to do that. For custom models, the mechanism will vary.

The sort indicator changes direction to indicate normal sort or reverse sort. Note that you must have the sort indicator enabled to see anything when calling this function; see set_sort_indicator().

Parameters

  order | Sort order that the sort indicator should indicate.

void Gtk::TreeViewColumn::set_spacing | ( | int | spacing | ) |

Sets the spacing field of tree_column, which is the number of pixels to place between cell renderers packed into it.

Parameters

  spacing | Distance between cell renderers in pixels.

void Gtk::TreeViewColumn::set_title | ( | const Glib::ustring & | title | ) |

Sets the title of the tree_column.

Slot Prototype:
  `void on_my_clicked()`

Flags: Run Last

void Gtk::TreeViewColumn::unset_cell_data_func | ( | CellRenderer& | cell_renderer | ) |

Removes a previously set callback slot.

See set_cell_data_func().
