ScrollableToolbar Class

Detailed Description

ScrollableToolbar hosts a horizontal row of child widgets (buttons, separators, combo boxes, labels, etc.) inside a QScrollArea. The scrollbar appears only when the content exceeds the available width — so on wide windows the toolbar looks like a conventional QHBoxLayout-backed toolbar, and on narrow windows (e.g. a phone in portrait orientation) the user can swipe horizontally to reach off-screen items rather than seeing them truncated or clipped.

This encapsulates the pattern originally implemented in Banter's BanterBusWidget; it's used there as well as in ConstructShell's top toolbar.
