◆ CalcMinimumSize()

Size cloudViewer::visualization::gui::ListView::CalcMinimumSize ( const LayoutContext & context ) const

Reimplemented from cloudViewer::visualization::gui::Widget.

Definition at line 101 of file ListView.cpp.

References context.

◆ CalcPreferredSize()

Size cloudViewer::visualization::gui::ListView::CalcPreferredSize	(	const LayoutContext &	context,
		const Constraints &	constraints
	)		const

overridevirtual

Reimplemented from cloudViewer::visualization::gui::Widget.

Definition at line 76 of file ListView.cpp.

References cloudViewer::utility::ceil(), context, cloudViewer::visualization::gui::Widget::DIM_GROW, max(), min(), size, and cloudViewer::visualization::gui::Widget::Constraints::width.

◆ Draw()

Widget::DrawResult cloudViewer::visualization::gui::ListView::Draw ( const DrawContext & context )

overridevirtual

Draws the widget. If this is a Dear ImGUI widget, this is where the actual event processing happens. Return NONE if no action needs to be taken, REDRAW if the widget needs to be redrawn (e.g. its value changed), and RELAYOUT if the widget wishes to change size.
