Fix app crash when clicking spaces after slide page items in presentation demo. #976

Closed Zhwt closed 4 months ago

Zhwt commented 5 months ago

The SetHighlightedFunc function is missing boundary check, so when clicking outside of available item list, it will panic with out of bound error.

Fixed by checking slice length first.
