Member Typedef Documentation

◆ SlotCompare

typedef sigc::slot<int, const Gtk::TreeModel::iterator&, const Gtk::TreeModel::iterator&> Gtk::TreeSortable::SlotCompare

This callback should return -1 if a compares before b, 0 if they compare equal, 1 if a compares after b. For instance, int on_sort_compare(const Gtk::TreeModel::iterator& a, const Gtk::TreeModel::iterator& b);

◆ get_sort_column_id()

bool Gtk::TreeSortable::get_sort_column_id	(	int &	sort_column_id,
		SortType &	order
	)		const

Fills in sort_column_id and order with the current sort column and the order. It returns true unless the sort_column_id is Gtk::TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID or Gtk::TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID.

Parameters

sort_column_id	The sort column id to be filled in.
order	The Gtk::SortType to be filled in.

Returns: true if the sort column is not one of the special sort column ids.

static

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

◆ has_default_sort_func()

bool Gtk::TreeSortable::has_default_sort_func ( ) const

Returns true if the model has a default sort function. This is used primarily by GtkTreeViewColumns in order to determine if a model can go back to the default state, or not.

Returns: true, if the model has a default sort function.

◆ has_default_sort_func_vfunc()

virtual bool Gtk::TreeSortable::has_default_sort_func_vfunc ( ) const

protectedvirtual

◆ on_sort_column_changed()

virtual void Gtk::TreeSortable::on_sort_column_changed ( )

protectedvirtual

This is a default handler for the signal signal_sort_column_changed().

◆ set_default_sort_func()

void Gtk::TreeSortable::set_default_sort_func ( const SlotCompare & slot )

Sets the default comparison function used when sorting. If the current sort column id of sortable is DEFAULT_SORT_COLUMN_ID, then the model will sort using this function. See also unset_default_sort_func().

Parameters

slot	The sorting function

◆ set_default_sort_func_vfunc()

virtual void Gtk::TreeSortable::set_default_sort_func_vfunc	(	GtkTreeIterCompareFunc	func,
		void *	data,
		GDestroyNotify	destroy
	)

protectedvirtual

◆ set_sort_column() [1/2]

void Gtk::TreeSortable::set_sort_column	(	const TreeModelColumnBase &	sort_column_id,
		SortType	order
	)

Sets the current sort column to be sort_column_id. The sortable will resort itself to reflect this change, after emitting a Gtk::TreeSortable::signal_sort_column_changed() signal. sort_column_id may either be a regular column id, or one of the following special values:

Gtk::TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID: the default sort function will be used, if it is set
Gtk::TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID: no sorting will occur

Parameters

sort_column_id	The sort column id to set.
order	The sort order of the column.

◆ set_sort_column() [2/2]

void Gtk::TreeSortable::set_sort_column	(	int	sort_column_id,
		SortType	order
	)

Sets the current sort column to be sort_column_id. The sortable will resort itself to reflect this change, after emitting a Gtk::TreeSortable::signal_sort_column_changed() signal. sort_column_id may either be a regular column id, or one of the following special values:

Gtk::TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID: the default sort function will be used, if it is set
Gtk::TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID: no sorting will occur

Parameters

sort_column_id	The sort column id to set.
order	The sort order of the column.

◆ set_sort_column_id() [1/2]

void Gtk::TreeSortable::set_sort_column_id	(	const TreeModelColumnBase &	sort_column_id,
		SortType	order
	)

◆ set_sort_column_id() [2/2]

void Gtk::TreeSortable::set_sort_column_id	(	int	sort_column_id,
		SortType	order
	)

◆ set_sort_column_id_vfunc()

virtual void Gtk::TreeSortable::set_sort_column_id_vfunc	(	int	sort_column_id,
		SortType	order
	)

protectedvirtual

◆ set_sort_func() [1/2]

void Gtk::TreeSortable::set_sort_func	(	const TreeModelColumnBase &	sort_column,
		const SlotCompare &	slot
	)

Sets the comparison function used when sorting a certain column. If the current sort column is the same as sort_column, then the model will sort using this function.

Parameters

sort_column	the sort column to set the function for
slot	The sorting slot callback.

◆ set_sort_func() [2/2]

void Gtk::TreeSortable::set_sort_func	(	int	sort_column_id,
		const SlotCompare &	slot
	)

Sets the comparison function used when sorting a certain column. If the current sort column id is the same as sort_column_id, then the model will sort using this function.

Parameters

sort_column_id	the sort column id to set the function for
slot	The sorting slot callback.

◆ set_sort_func_vfunc()

virtual void Gtk::TreeSortable::set_sort_func_vfunc	(	int	sort_column_id,
		GtkTreeIterCompareFunc	func,
		void *	data,
		GDestroyNotify	destroy
	)

protectedvirtual

◆ signal_sort_column_changed()

Glib::SignalProxy0< void > Gtk::TreeSortable::signal_sort_column_changed ( )

Slot Prototype:: void on_my_sort_column_changed()

◆ sort_column_changed()

void Gtk::TreeSortable::sort_column_changed ( )

Emits a Gtk::TreeSortable::signal_sort_column_changed() signal on sortable.

◆ sort_column_changed_vfunc()

virtual void Gtk::TreeSortable::sort_column_changed_vfunc ( ) const

protectedvirtual

◆ unset_default_sort_func()

void Gtk::TreeSortable::unset_default_sort_func ( )

Sets the default comparison function used when sorting. See set_default_sort_func().

After calling this method there will be no default comparison function. This means that once the model has been sorted, it can't go back to the default state. In this case, when the current sort column id of sortable is DEFAULT_SORT_COLUMN_ID, the model will be unsorted.

◆ wrap()

Glib::RefPtr< Gtk::TreeSortable > wrap	(	GtkTreeSortable *	object,
		bool	take_copy = `false`
	)

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns: A C++ instance that wraps this C instance.
