StackedWidget(Widget) (open3d.cuda.pybind.visualization.gui.StackedWidget) - Like a TabControl but without the tabs
TabControl(Widget) (open3d.cuda.pybind.visualization.gui.TabControl) - Tab control
WidgetProxy(Widget) (open3d.cuda.pybind.visualization.gui.WidgetProxy) - Widget container to delegate any widget dynamically. Widget can not be managed dynamically. Although it is allowed to add more child widgets, it's impossible to replace some child with new on or remove children. WidgetProxy is designed to solve this problem. When WidgetProxy is created, it's invisible and disabled, so it won't be drawn or layout, seeming like it does not exist. When a widget is set by set_widget, all Widget's APIs will be conducted to that child widget. It looks like WidgetProxy is that widget. At any time, a new widget could be set, to replace the old one. and the old widget will be destroyed. Due to the content changing after a new widget is set or cleared, a relayout of Window might be called after set_widget. The delegated widget could be retrieved by get_widget in case you need to access it directly, like get check status of a CheckBox. API other than set_widget and get_widget has completely same functions as Widget.
WidgetStack(WidgetProxy) (open3d.cuda.pybind.visualization.gui.WidgetStack) - A widget stack saves all widgets pushed into by push_widget and always shows the top one. The WidgetStack is a subclass of WidgetProxy, in otherwords, the topmost widget will delegate itself to WidgetStack. pop_widget will remove the topmost widget and callback set by set_on_top taking the new topmost widget will be called. The WidgetStack disappears in GUI if there is no widget in stack.
