Public Member Functions
virtual void	setOpen (bool open)=0
	Shows or hides it. Never calls the onDismiss handler.
virtual void	setTitle (std::string_view title)=0
	Replaces the title.
virtual void	setOnDismiss (Action onDismiss)=0
	Sets what a user dismissal (Esc on the TUI) calls.
virtual ContainerWidget &	footer ()=0
	The drawer's footer: a container it lays out after its content, which shows nothing while it is empty. The mount puts the drawer's actions here.
Public Member Functions inherited from morph::ui::ContainerWidget
virtual void	moveChild (Widget &child, std::size_t index)=0
	Moves child to position index: it is removed, then inserted before the child now at index.
Public Member Functions inherited from morph::ui::Widget
	Widget (Widget const &)=delete
Widget &	operator= (Widget const &)=delete
	Widget (Widget &&)=delete
Widget &	operator= (Widget &&)=delete
virtual void	setVisible (bool visible)=0
	Shows or hides the widget and everything inside it.
virtual void	setEnabled (bool enabled)=0
	Enables or disables input on the widget and everything inside it.
virtual void	setLayout (LayoutHints const &hints)=0
	Sets the size request.
virtual void	setDragKey (std::optional< Key > const &key)=0
	Makes the widget draggable, carrying key, or not draggable.
virtual void	setDropHandler (std::function< bool(Key const &)> accepts, std::function< void(Key)> onDrop)=0
	Makes the widget a drop target.
virtual void	setAccessibleName (std::string_view name)=0
	Sets the name assistive technology reads for the widget.
virtual void	setAccessibleRole (std::string_view role)=0
	Sets the role assistive technology announces for the widget.
virtual void	setTestId (std::string_view testId)=0
	Sets the stable identifier an automated test finds the widget by.
virtual void	setTooltip (std::string_view text)=0
	Sets the text shown while the pointer rests on the widget.
virtual void	setSurface (std::string_view surface)=0
	Styles the widget and everything inside it with a named token set of the theme.
virtual void	setKeys (std::vector< std::string > const &chords, std::function< void(std::string)> onChord)=0
	Declares the keyboard chords the widget handles while focus is inside it.
virtual void	focus ()=0
	Moves keyboard focus to the widget.
virtual void	setOnHover (std::function< void()> onHover)
	Calls onHover each time the pointer comes to rest over the widget. A backend without a pointer, or one that does not report hovering, keeps the default, which never calls it: hovering is a hint, such as a prefetch, never something a widget relies on.

Member Function Documentation

setOpen()

virtual void morph::ui::DrawerWidget::setOpen ( bool open )

pure virtual

Shows or hides it. Never calls the onDismiss handler.

Parameters

open	Whether it is shown.

Implemented in morph::ui::testing::detail::FakeDrawer.

setTitle()

virtual void morph::ui::DrawerWidget::setTitle ( std::string_view title )

pure virtual

Replaces the title.

Parameters

title

The title, UTF-8.

Implemented in morph::ui::testing::detail::FakeDrawer.

setOnDismiss()

virtual void morph::ui::DrawerWidget::setOnDismiss ( Action onDismiss )

pure virtual

Sets what a user dismissal (Esc on the TUI) calls.

Parameters

onDismiss

The handler; empty does nothing.

Implemented in morph::ui::testing::detail::FakeDrawer.

footer()

virtual ContainerWidget & morph::ui::DrawerWidget::footer ( )

pure virtual

The drawer's footer: a container it lays out after its content, which shows nothing while it is empty. The mount puts the drawer's actions here.
