Detailed Description

Abstract container class.

This is the abstract container from which all gtk+ widgets which hold other items derive from. It mainly houses virtual functions used for inserting and removing children. Containers in gtk+ may hold one item or many items depending on the implementation.

This interface is used for all single item holding containers. Multi-item containers provide their own unique interface as their items are generally more complex. The methods of the derived classes should be prefered over these.

Member Function Documentation

virtual void Gtk::Container::add ( Widget& widget )

virtual

Reimplemented in Gtk::ScrolledWindow.

void Gtk::Container::check_resize ( )

Request that contained widgets check their size.

GType Gtk::Container::child_type ( ) const

Returns the type of the children supported by the container.

Note that this may return TYPE_NONE to indicate that no more children can be added, e.g. for a Gtk::Paned which already has two children.

Returns:: A Type.

virtual GType Gtk::Container::child_type_vfunc ( ) const

protectedvirtual

Implements child_type().

The default implementation returns G_TYPE_NONE

virtual char* Gtk::Container::composite_name_vfunc ( GtkWidget * child )

protectedvirtual

Returns the composite name of a child widget.

Composite widgets are children of the container that are considered "internal" (implementation details of the container). "Internal" children generally weren't added by the user of the container, but were added by the container implementation itself.

The caller is responsible for freeing the returned string.

Parameters:

child The child widget.

Returns:: The composite name of the child widget.

void Gtk::Container::forall ( const ForeachSlot& slot )

Operate on contained items, including internal children.

Invokes the @ slot on each child of the container, including children that are considered "internal" (implementation details of the container). "Internal" children generally weren't added by the user of the container, but were added by the container implementation itself. Most applications should use foreach(), rather than forall().

Since gtkmm 3.6:

virtual void Gtk::Container::forall_vfunc	(	gboolean	include_internals,
		GtkCallback	callback,
		gpointer	callback_data
	)

protectedvirtual

Invokes a callback on all children of the container.

The callback may optionally be invoked also on children that are considered "internal" (implementation details of the container). "Internal" children generally weren't added by the user of the container, but were added by the container implementation itself.

Most applications should use foreach(), rather than forall().

Parameters:

include_internals
callback	A callback.
callback_data	Callback user data

void Gtk::Container::foreach ( const ForeachSlot& slot )

Operate on contained items.

Invokes the slot on each non-internal child of the container. See forall() for details on what constitutes an "internal" child. Most applications should use foreach() rather than forall().

guint Gtk::Container::get_border_width ( ) const

Retrieves the border width of the container.

See set_border_width().

Returns:: The current border width.

virtual void Gtk::Container::get_child_property_vfunc	(	GtkWidget *	child,
		guint	property_id,
		GValue *	value,
		GParamSpec *	pspec
	)		const

protectedvirtual

Returns a child property for this container and its child.

Child properties are object properties that are not specific to either the container or the contained widget, but rather to their relation. Typical examples of child properties are the position or pack-type of a widget which is contained in a Gtk::Box.

Parameters:

child	The child property.
property_id	The ID of the child property to get.
value	A GValue to fill with the child property's value.
pspec

std::vector<Widget*> Gtk::Container::get_children ( )

(internal) Operate on contained items (see foreach())

(internal) Operate on contained items (see foreach()) Returns the container's non-internal children. See forall() for details on what constitutes an "internal" child.

Returns:: A newly-allocated list of the container's non-internal children.

std::vector<const Widget*> Gtk::Container::get_children ( ) const

Returns the container's non-internal children.

See forall() for details on what constitutes an "internal" child.

Returns:: A newly-allocated list of the container's non-internal children.

std::vector<Widget*> Gtk::Container::get_focus_chain ( )

std::vector<const Widget*> Gtk::Container::get_focus_chain ( ) const

Widget* Gtk::Container::get_focus_child ( )

Returns the current focus child widget inside container.

This is not the currently focused widget. That can be obtained by calling Gtk::Window::get_focus().

Since gtkmm 2.14:

Returns:: The child widget which will receive the focus inside container when the conatiner is focussed, or 0 if none is set.

const Widget* Gtk::Container::get_focus_child ( ) const

Returns the current focus child widget inside container.

This is not the currently focused widget. That can be obtained by calling Gtk::Window::get_focus().

Since gtkmm 2.14:

Returns:: The child widget which will receive the focus inside container when the conatiner is focussed, or 0 if none is set.

Glib::RefPtr<Adjustment> Gtk::Container::get_focus_hadjustment ( )

Retrieves the horizontal focus adjustment for the container.

See set_focus_hadjustment().

Returns:: The horizontal focus adjustment, or 0 if none has been set.

Glib::RefPtr<const Adjustment> Gtk::Container::get_focus_hadjustment ( ) const

Retrieves the horizontal focus adjustment for the container.

See set_focus_hadjustment().

Returns:: The horizontal focus adjustment, or 0 if none has been set.

Glib::RefPtr<Adjustment> Gtk::Container::get_focus_vadjustment ( )

Retrieves the vertical focus adjustment for the container.

See set_focus_vadjustment().

Returns:: The vertical focus adjustment, or 0 if none has been set.

Glib::RefPtr<const Adjustment> Gtk::Container::get_focus_vadjustment ( ) const

See set_focus_vadjustment().

Returns:: The vertical focus adjustment, or 0 if none has been set.

WidgetPath Gtk::Container::get_path_for_child ( const Widget& child ) const

Returns a newly created widget path representing all the widget hierarchy from the toplevel down to and including child.

Parameters:

child A child of container.

Returns:: A newly created Gtk::WidgetPath.

ResizeMode Gtk::Container::get_resize_mode ( ) const

Returns the resize mode for the container.

See set_resize_mode().

void Gtk::Container::propagate_draw	(	Widget&	child,
		const ::Cairo::RefPtr< ::Cairo::Context > &	cr
	)

When a container receives a call to the draw function, it must send synthetic Gtk::Widget::signal_draw() calls to all children that don't have their own Gdk::Windows.

This function provides a convenient way of doing this. A container, when it receives a call to its Gtk::Widget::signal_draw() function, calls propagate_draw() once for each child, passing in the cr the container received.

propagate_draw() takes care of translating the origin of cr, and deciding whether the draw needs to be sent to the child. It is a convenient and optimized way of getting the same effect as calling Gtk::Widget::draw() on the child directly.

In most cases, a container can simply either inherit the Gtk::Widget::signal_draw() implementation from Gtk::Container, or do some drawing and then chain to the signal_draw() implementation from Gtk::Container.

Parameters:

child	A child of container.
cr	Cairo context as passed to the container. If you want to use cr in container's draw function, consider using cairo_save() and cairo_restore() before calling this function.

Glib::PropertyProxy< guint > Gtk::Container::property_border_width ( )

protected
