Jazz2::UI::Menu::ScrollView class

#include <Jazz2/UI/Menu/MenuWidgets.h>

Vertical list that scrolls when its children overflow the available area.

Centers the content when it fits, otherwise clamps a scroll offset and supports kinetic touch dragging, keyboard scrolling (keeping the selected item visible), and scroll-edge fade glows.

auto OnTouchEvent(const nCine::TouchEvent& event, Vector2i viewSize, IMenuContainer* root) -> bool override

Handles a touch event; returns true if it was consumed.

Public variables

float ContentPadding

Empty space reserved before the first and after the last item so they aren't flush against the frame; sections with oversized rows can raise it.

Called when the selection moves, so a scrolling container can keep it visible.

void OnSelectionSet() override

Called when the selection is set programmatically, so a scrolling container can reveal it.
