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.

◆ add_attribute() [1/3]

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

◆ add_attribute() [2/3]

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.

◆ add_attribute() [3/3]

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

◆ add_attribute_vfunc()

virtual void Gtk::CellLayout::add_attribute_vfunc	(	CellRenderer *	cell,
		const Glib::ustring &	attribute,
		int	column
	)

protectedvirtual

◆ add_interface()

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

static

◆ clear()

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:

◆ clear_attributes()

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.

◆ clear_attributes_vfunc()

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

protectedvirtual

◆ clear_vfunc()

virtual void Gtk::CellLayout::clear_vfunc ( )

protectedvirtual

◆ get_area() [1/2]

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 nullptr if no Gtk::CellArea is used by cell_layout.

Since gtkmm 3.0:

Returns: The cell area used by cell_layout, or nullptr in case no cell area is used.

◆ get_area() [2/2]

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 nullptr if no Gtk::CellArea is used by cell_layout.

Since gtkmm 3.0:

Returns: The cell area used by cell_layout, or nullptr in case no cell area is used.

◆ get_cells() [1/2]

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

Return value: a list of cell renderers.

Since gtkmm 2.12:

Returns: A list of cell renderers.

◆ get_cells() [2/2]

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.

◆ get_first_cell() [1/2]

CellRenderer * Gtk::CellLayout::get_first_cell ( )

Gets the CellRenderer for the first column if any has been added, or nullptr otherwise.

You should dynamic_cast<> to the expected derived CellRenderer type.

◆ get_first_cell() [2/2]

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

Gets the CellRenderer for the first column if any has been added, or nullptr otherwise.

You should dynamic_cast<> to the expected derived CellRenderer type.

◆ get_type()

static GType Gtk::CellLayout::get_type ( )

static

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

◆ gobj() [1/2]

GtkCellLayout * Gtk::CellLayout::gobj ( )

inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

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

inline

Provides access to the underlying C GObject.

◆ operator=()

CellLayout & Gtk::CellLayout::operator= ( CellLayout && src )

noexcept

◆ pack_end()

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.

◆ pack_end_vfunc()

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

protectedvirtual

◆ pack_start() [1/3]

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.

◆ pack_start() [2/3]

template <class ColumnType >

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

◆ pack_start() [3/3]

template <class T_ModelColumnType >

void Gtk::CellLayout::pack_start	(	const TreeModelColumn< T_ModelColumnType > &	column,

	)

◆ pack_start_vfunc()

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

protectedvirtual

◆ reorder()

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.

◆ reorder_vfunc()

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

protectedvirtual

◆ set_cell_data_func()

void Gtk::CellLayout::set_cell_data_func	(	CellRenderer &	cell,
		const SlotCellData &	slot

◆ wrap()

Glib::RefPtr< Gtk::CellLayout > wrap	(	GtkCellLayout *	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.
