	Makes the widget a drop target.

	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.

Detailed Description

A widget with children. A factory given this container appends the new widget as its last child.

Member Function Documentation

moveChild()

virtual void morph::ui::ContainerWidget::moveChild ( Widget & child, std::size_t index )

pure virtual

Moves child to position index: it is removed, then inserted before the child now at index.

The child is moved, not recreated: it keeps its native state, such as its properties, handlers, focus and selection.

Parameters

child	One of this container's children.
index	The new position; past the end means last.

Implemented in morph::ui::testing::detail::FakeContainer< CollapsibleWidget >, morph::ui::testing::detail::FakeContainer< DialogWidget >, morph::ui::testing::detail::FakeContainer< DrawerWidget >, morph::ui::testing::detail::FakeContainer< DropZoneWidget >, morph::ui::testing::detail::FakeContainer< GridWidget >, morph::ui::testing::detail::FakeContainer< morph::ui::SlotWidget >, morph::ui::testing::detail::FakeContainer< PanelWidget >, morph::ui::testing::detail::FakeContainer< SplitterWidget >, morph::ui::testing::detail::FakeContainer< StackWidget >, morph::ui::testing::detail::FakeContainer< TableWidget >, and morph::ui::testing::detail::FakeContainer< TabsWidget >.
