Тоесть если взять emit angleChanged(currentAngle); то дальше в слот будет передаваться параметр currentAngle?

bool QAbstractSocket::flush ()
This function writes as much as possible from the internal write buffer to the underlying network socket, without blocking. If any data was written, this function returns true; otherwise false is returned.

Call this function if you need QAbstractSocket to start sending buffered data immediately. The number of bytes successfully written depends on the operating system. In most cases, you do not need to call this function, because QAbstractSocket will start sending data automatically once control goes back to the event loop. In the absence of an event loop, call waitForBytesWritten() instead.

See also write() and waitForBytesWritten().

QUrl::QUrl ( const QString & url, ParsingMode parsingMode )
This is an overloaded function.

Parses the url using the parser mode parsingMode.

enum QUrl::ParsingMode
The parsing mode controls the way QUrl parses strings.

Constant Value Description
QUrl::TolerantMode 0 QUrl will try to correct some common errors in URLs. This mode is useful when processing URLs entered by users.
QUrl::StrictMode 1 Only valid URLs are accepted. This mode is useful for general URL validation.
In TolerantMode, the parser corrects the following invalid input:

Spaces and "%20": If an encoded URL contains a space, this will be replaced with "%20". If a decoded URL contains "%20", this will be replaced with a single space before the URL is parsed.
Single "%" characters: Any occurrences of a percent character "%" not followed by exactly two hexadecimal characters (e.g., "13% coverage.html") will be replaced by "%25".
Reserved and unreserved characters: An encoded URL should only contain a few characters as literals; all other characters should be percent-encoded. In TolerantMode, these characters will be automatically percent-encoded where they are not allowed: space / double-quote / "<" / ">" / "[" / "" / "]" / "^" / "`" / "{" / "|" / "}"

ага спасибо, вот эта конструкция работает, хотя она намного длиньше чем просто Sleep(); )))))))

parent() возвращает непустой указатель, значит есть. Но это ведь объект класс QObject?
