đây là mã được tạo từ tệp qt ui
, tôi thấy rằng mã sử dụng new
từ khóa để phân bổ bộ nhớ nhưng không có từ khóa trong lớp để xóa tài nguyên được phân bổ, là lỗi này qt các nhà phát triển hoặc có cái gì khác (không có tài nguyên deallocated)?Qt UI Generator không giải quyết tài nguyên

là có nghĩa là tôi nên viết lại mã để giải phóng bộ nhớ (unique
_ptr ví dụ) và mã nên được như thế này

Bạn có thể cắt bức tường mã đó thành các phần quan trọng không? – arne
