Member Function Documentation

rebuildUI()

void Chesto::DropDownControllerElement::rebuildUI ( )

inlineoverridevirtual

Rebuild the entire UI for this screen. Called on initialization and whenever the screen needs to be reconstructed (e.g., theme changes, language changes).

Implementations should:

1. Call removeAll() to clear existing UI
2. Create all UI elements with std::make_unique
3. Configure elements (position, actions, etc.)
4. Transfer ownership via append(std::move(...))

Implements Chesto::Screen.
