Detailed Description

A container that shows only one child at a time.

Gtk::Stack does not provide a means for users to change the visible child. Instead, the Gtk::StackSwitcher or Gtk::StackSidebar widget can be used with Gtk::Stack to provide this functionality.

Gtk::Stack maintains a Gtk::StackPage object for each added child, which holds additional per-child properties. You obtain the Gtk::StackPage for a child with get_page().

Since gtkmm 3.10:

Member Function Documentation

Glib::RefPtr<StackPage> Gtk::Stack::add ( Widget& child )

Adds a child to stack.

Parameters

child The widget to add.

Returns: The Gtk::StackPage for child.

Glib::RefPtr<StackPage> Gtk::Stack::add	(	Widget&	child,
		const Glib::ustring &	name
	)

Adds a child to stack.

The child is identified by the name.

Parameters

child	The widget to add.
name	The name for child or `nullptr`.

Returns: The Gtk::StackPage for child.

Glib::RefPtr<StackPage> Gtk::Stack::add	(	Widget&	child,
		const Glib::ustring &	name,
		const Glib::ustring &	title
	)

Adds a child to stack.

The child is identified by the name. The title will be used by Gtk::StackSwitcher to represent child in a tab bar, so it should be short.

Parameters

child	The widget to add.
name	The name for child.
title	A human-readable title for child.

Returns: The Gtk::StackPage for child.

Widget* Gtk::Stack::get_child_by_name ( const Glib::ustring & name )

Finds the child of the Gtk::Stack with the name given as the argument.

Returns nullptr if there is no child with this name.

Parameters

name	The name of the child to find.

Returns: The requested child of the Gtk::Stack.

const Widget* Gtk::Stack::get_child_by_name ( const Glib::ustring & name ) const

Finds the child of the Gtk::Stack with the name given as the argument.

Returns nullptr if there is no child with this name.

Parameters

name	The name of the child to find.

Returns: The requested child of the Gtk::Stack.

bool Gtk::Stack::get_hhomogeneous ( ) const

Gets whether stack is horizontally homogeneous.

See set_hhomogeneous().

Returns: Whether stack is horizontally homogeneous.

bool Gtk::Stack::get_interpolate_size ( ) const

Returns whether the Gtk::Stack is set up to interpolate between the sizes of children on page switch.

Since gtkmm 3.20:

Returns: true if child sizes are interpolated.

Glib::RefPtr<StackPage> Gtk::Stack::get_page ( Widget& child )

Returns the Gtk::StackPage object for child.

Parameters

child A child of stack.

Returns: The Gtk::StackPage for child.

Glib::RefPtr<const StackPage> Gtk::Stack::get_page ( const Widget& child ) const

Returns the Gtk::StackPage object for child.

Parameters

child A child of stack.

Returns: The Gtk::StackPage for child.

Glib::RefPtr<SelectionModel> Gtk::Stack::get_pages ( )

Returns a ListModel that contains the pages of the stack, and can be used to keep an up-to-date view.

The model also implements Gtk::SelectionModel and can be used to track and modify the visible page.

Returns: A Gtk::SelectionModel for the stack's children.

Glib::RefPtr<const SelectionModel> Gtk::Stack::get_pages ( ) const

Returns a ListModel that contains the pages of the stack, and can be used to keep an up-to-date view.

The model also implements Gtk::SelectionModel and can be used to track and modify the visible page.

Returns: A Gtk::SelectionModel for the stack's children.

guint Gtk::Stack::get_transition_duration ( ) const

Returns the amount of time (in milliseconds) that transitions between pages in stack will take.

Returns: The transition duration.

bool Gtk::Stack::get_transition_running ( ) const

Returns whether the stack is currently in a transition from one page to another.

Returns: true if the transition is currently running, false otherwise.

StackTransitionType Gtk::Stack::get_transition_type ( ) const

Gets the type of animation that will be used for transitions between pages in stack.

Returns: The current transition type of stack.

static GType Gtk::Stack::get_type ( )

static

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

bool Gtk::Stack::get_vhomogeneous ( ) const

Gets whether stack is vertically homogeneous.

See set_vhomogeneous().

Returns: Whether stack is vertically homogeneous.

Widget* Gtk::Stack::get_visible_child ( )

Gets the currently visible child of stack, or nullptr if there are no visible children.

Returns: The visible child of the Gtk::Stack.

const Widget* Gtk::Stack::get_visible_child ( ) const

Gets the currently visible child of stack, or nullptr if there are no visible children.

Returns: The visible child of the Gtk::Stack.

Glib::ustring Gtk::Stack::get_visible_child_name ( ) const

Returns the name of the currently visible child of stack, or nullptr if there is no visible child.

Returns: The name of the visible child of the Gtk::Stack.

GtkStack* Gtk::Stack::gobj ( )

void Gtk::Stack::remove ( Widget& child )

Removes a child widget from stack.

Parameters

child The child to remove.

void Gtk::Stack::set_hhomogeneous ( bool hhomogeneous = true )

Sets the Gtk::Stack to be horizontally homogeneous or not.

If it is homogeneous, the Gtk::Stack will request the same width for all its children. If it isn't, the stack may change width when a different child becomes visible.

Parameters

hhomogeneous true to make stack horizontally homogeneous.

void Gtk::Stack::set_interpolate_size ( bool interpolate_size )

Sets whether or not stack will interpolate its size when changing the visible child.

If the Gtk::Stack::property_interpolate_size() property is set to true, stack will interpolate its size between the current one and the one it'll take after changing the visible child, according to the set transition duration.

Since gtkmm 3.20:

Parameters

interpolate_size The new value.

void Gtk::Stack::set_transition_duration ( guint duration )

Sets the duration that transitions between pages in stack will take.

Parameters

duration The new duration, in milliseconds.

void Gtk::Stack::set_transition_type ( StackTransitionType transition )

Sets the type of animation that will be used for transitions between pages in stack.

Available types include various kinds of fades and slides.

The transition type can be changed without problems at runtime, so it is possible to change the animation based on the page that is about to become current.

Parameters

transition The new transition type.

void Gtk::Stack::set_vhomogeneous ( bool vhomogeneous = true )

Sets the Gtk::Stack to be vertically homogeneous or not.

If it is homogeneous, the Gtk::Stack will request the same height for all its children. If it isn't, the stack may change height when a different child becomes visible.

Parameters

vhomogeneous true to make stack vertically homogeneous.

void Gtk::Stack::set_visible_child ( Widget& child )

Makes child the visible child of stack.

If child is different from the currently visible child, the transition between the two will be animated with the current transition type of stack.

Note that the child widget has to be visible itself (see Gtk::Widget::show()) in order to become the visible child of stack.

Parameters

child A child of stack.

void Gtk::Stack::set_visible_child ( const Glib::ustring & name )

Makes the child with the given name visible.

If child is different from the currently visible child, the transition between the two will be animated with the current transition type of stack.

Note that the child widget has to be visible itself (see Gtk::Widget::show()) in order to become the visible child of stack.

Parameters

name	The name of the child to make visible.

void Gtk::Stack::set_visible_child	(	const Glib::ustring &	name,
		StackTransitionType	transition
	)

Makes the child with the given name visible.

Note that the child widget has to be visible itself (see Gtk::Widget::show()) in order to become the visible child of stack.

Parameters

name	The name of the child to make visible.
transition	The transition type to use.
