Detailed Description

CellRenderers are used by Gtk::TreeView columns to render the Gtk::TreeModel column data appropriately.

They display, and allow editing of, the values of their properties. In most cases, Gtk::TreeView::append_column() will automatically choose the appropriate renderer for the mode column's data type, so you will rarely need to worry about these classes.

Glib::PropertyProxy< unsigned int > Gtk::CellRenderer::property_ypad ( )

The ypad.

Default value: 0

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_ypad() [2/2]

Glib::PropertyProxy_ReadOnly< unsigned int > Gtk::CellRenderer::property_ypad ( ) const

The ypad.

Default value: 0

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ render()

void Gtk::CellRenderer::render	(	const ::Cairo::RefPtr< ::Cairo::Context > &	cr,
		Widget &	widget,
		const Gdk::Rectangle &	background_area,
		const Gdk::Rectangle &	cell_area,
		CellRendererState	flags
	)

Invokes the virtual render function of the Gtk::CellRenderer.

The three passed-in rectangles are areas in cr. Most renderers will draw within cell_area; the xalign, yalign, xpad, and ypad fields of the Gtk::CellRenderer should be honored with respect to cell_area. background_area includes the blank space around the cell, and also the area containing the tree expander; so the background_area rectangles for all cells tile to cover the entire window.

Parameters

cr	A cairo context to draw to.
widget	The widget owning window.
background_area	Entire cell area (including tree expanders and maybe padding on the sides).
cell_area	Area normally rendered by a cell renderer.
flags	Flags that affect rendering.

◆ render_vfunc()

virtual void Gtk::CellRenderer::render_vfunc	(	const ::Cairo::RefPtr< ::Cairo::Context > &	cr,
		Widget &	widget,
		const Gdk::Rectangle &	background_area,
		const Gdk::Rectangle &	cell_area,
		CellRendererState	flags
	)

◆ set_alignment()

void Gtk::CellRenderer::set_alignment	(	float	xalign,
		float	yalign
	)

Sets the renderer’s alignment within its available space.

Since gtkmm 2.18:

Parameters

xalign	The x alignment of the cell renderer.
yalign	The y alignment of the cell renderer.

◆ set_fixed_size()

void Gtk::CellRenderer::set_fixed_size	(	int	width,
		int	height
	)

Sets the renderer size to be explicit, independent of the properties set.

Parameters

width	The width of the cell renderer, or -1.
height	The height of the cell renderer, or -1.

◆ set_padding()

void Gtk::CellRenderer::set_padding	(	int	xpad,
		int	ypad
	)

Sets the renderer’s padding.

Since gtkmm 2.18:

Parameters

xpad	The x padding of the cell renderer.
ypad	The y padding of the cell renderer.

◆ set_sensitive()

void Gtk::CellRenderer::set_sensitive ( bool sensitive = true )

Sets the cell renderer’s sensitivity.

Since gtkmm 2.18:

Parameters

sensitive The sensitivity of the cell.

◆ set_visible()

void Gtk::CellRenderer::set_visible ( bool visible = true )

Sets the cell renderer’s visibility.

Since gtkmm 2.18:

Parameters

visible The visibility of the cell.

◆ signal_editing_canceled()

Glib::SignalProxy< void > Gtk::CellRenderer::signal_editing_canceled ( )

Slot Prototype:: void on_my_editing_canceled()

Flags: Run First

This signal gets emitted when the user cancels the process of editing a cell. For example, an editable cell renderer could be written to cancel editing when the user presses Escape.

Since gtkmm 2.4:

◆ signal_editing_started()

Glib::SignalProxy< void, CellEditable *, const Glib::ustring & > Gtk::CellRenderer::signal_editing_started ( )

Slot Prototype:: void on_my_editing_started(CellEditable* editable, const Glib::ustring& path)

Flags: Run First

This signal gets emitted when a cell starts to be edited. The intended use of this signal is to do special setup on editable, e.g. adding a Gtk::EntryCompletion or setting up additional columns in a Gtk::ComboBox.

See Gtk::CellEditable::start_editing() for information on the lifecycle of the editable and a way to do setup that doesn’t depend on the renderer.

Note that GTK+ doesn't guarantee that cell renderers will continue to use the same kind of widget for editing in future releases, therefore you should check the type of editable before doing any specific setup, as in the following example:

[C example ellipted]

Since gtkmm 2.6:

Parameters

editable	The Gtk::CellEditable.
path	The path identifying the edited cell.

◆ start_editing()

CellEditable * Gtk::CellRenderer::start_editing	(	GdkEvent *	event,
		Widget &	widget,
		const Glib::ustring &	path,
		const Gdk::Rectangle &	background_area,
		const Gdk::Rectangle &	cell_area,
		CellRendererState	flags = `CellRendererState(0)`
	)

Starts editing the contents of this cell, through a new Gtk::CellEditable widget created by the Gtk::CellRendererClass.start_editing virtual function.

Parameters

event	A Gdk::Event.
widget	Widget that received the event.
path	Widget-dependent string representation of the event location; e.g. for Gtk::TreeView, a string representation of Gtk::TreePath.
background_area	Background area as passed to render().
cell_area	Cell area as passed to render().
flags	Render flags.

Returns: A new Gtk::CellEditable for editing this cell, or nullptr if editing is not possible.

◆ start_editing_vfunc()

virtual CellEditable * Gtk::CellRenderer::start_editing_vfunc	(	GdkEvent *	event,
		Widget &	widget,
		const Glib::ustring &	path,
		const Gdk::Rectangle &	background_area,
		const Gdk::Rectangle &	cell_area,
		CellRendererState	flags
	)

protectedvirtual

◆ stop_editing()

void Gtk::CellRenderer::stop_editing ( bool canceled = false )

Informs the cell renderer that the editing is stopped.

If canceled is true, the cell renderer will emit the Gtk::CellRenderer::signal_editing_canceled() signal.

This function should be called by cell renderer implementations in response to the Gtk::CellEditable::signal_editing_done() signal of Gtk::CellEditable.

Since gtkmm 2.6:

Parameters

canceled true if the editing has been canceled.

◆ wrap()

Gtk::CellRenderer * wrap	(	GtkCellRenderer *	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.
