Detailed Description

Container to arrange widgets in a horizontal or vertical layout.

Member Function Documentation

◆ find_selectable()

widget* box::find_selectable	(	navigation_type	nt,
		point	center
	)

overridevirtual

Should return the first selectable widget according to the navigation type. If a widget is selectable it should return itself. Containers should return the first selectable child widget. Otherwise nullptr is returned.

The point may serve as a hint to provide a more accurate selection.

Implements container.

◆ get_children()

std::vector<widget *> box::get_children ( )

overridevirtual

Return child widgets in Z-order. Should be implemented by containers.

Implements container.

◆ get_size_hint()

size_hint box::get_size_hint	(	int	width,
		int	height
	)		const

overridevirtual

Computes the widgets preferred minimal and natural size. When given a specific width or height the widget might use that to give a more accurate size.

Implements widget.

◆ navigate_selectable_from_children()

widget* box::navigate_selectable_from_children	(	navigation_type	nt,
		widget *	w,
		point	center
	)

overridevirtual

When a child widget has exhausted its selectable widgets it may ask its parent for the next widget according to the navigation. The coordinates of the widget are provided to get a more accurate result for some navigation types (i.e. 2-dimensional). The widget passed has to be the direct child, otherwise the parent is not able to find it.

Only containers should implement this.

Reimplemented from widget.

◆ on_box_allocated()

void box::on_box_allocated ( )

overridevirtual

Refresh layout with existing box. This should not be called if the widget does not have a box already. Otherwise no space is allocated.

Implements container.
