Member Function Documentation

◆ find_selectable()

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

overridepure virtual

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.

Reimplemented from widget.

Implemented in box, and table.

◆ get_children()

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

overridepure virtual

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

Reimplemented from widget.

Implemented in box, and table.

◆ on_box_allocated()

void container::on_box_allocated ( )

overridepure virtual

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

Reimplemented from widget.

Implemented in box, and table.

◆ on_draw()

void container::on_draw	(	draw_context &	dc,
		selection_context const &	sc
	)		const

overridevirtual

Draw the widget. No children should be drawn here.

Implements widget.

The documentation for this struct was generated from the following file:
