## Detailed Description

The column added to Gtk::ColumnView.

Gtk::ColumnViewColumn represents the columns being added to Gtk::ColumnView.

Columns have a title, and can optionally have a header menu set with set_header_menu().

A sorter can be associated with a column using set_sorter(), to let users influence sorting by clicking on the column header.

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

Sets the column to take available extra space.

The extra space is shared equally amongst all columns that have the expand set to `true`.

Parameters

  expand | `true` if this column should expand to fill available sace.

void Gtk::ColumnViewColumn::set_factory | ( | const Glib::RefPtr< ListItemFactory > & | factory | ) |

Sets the `Gtk::ListItemFactory` to use for populating list items for this column.

Parameters

  factory | The factory to use.

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

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

Setting a fixed width overrides the automatically calculated width. Interactive resizing also sets the “fixed-width” property.

Parameters

  fixed_width | The new fixed width, or -1.

void Gtk::ColumnViewColumn::set_header_menu | ( | const Glib::RefPtr< Gio::MenuModel > & | model | ) |

Sets the menu model that is used to create the context menu for the column header.

Parameters

  model | A `Gio::MenuModel`.

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

Sets whether this column should be resizable by dragging.

Parameters

  resizable | Whether this column should be resizable.

void Gtk::ColumnViewColumn::set_sorter | ( | const Glib::RefPtr< Sorter > & | sorter | ) |

Associates a sorter with the column.

If sorter is `nullptr`, the column will not let users change the sorting by clicking on its header.

This sorter can be made active by clicking on the column header, or by calling sort_by_column().

See get_sorter() for the necessary steps for setting up customizable sorting for Gtk::ColumnView.

Parameters

  sorter | The `Gtk::Sorter` to associate with column.

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

Sets the title of this column.

The title is displayed in the header of a `Gtk::ColumnView` for this column and is therefore user-facing text that should be translated.

Parameters

  title | Title to use for this column.

void Gtk::ColumnViewColumn::set_visible | ( | bool | visible = `true` | ) |

Sets whether this column should be visible in views.

Parameters

  visible | Whether this column should be visible.
