Detailed Description▲
QQmlScriptString is used to create QObject properties that accept a script "assignment" from QML.
Normally, the following QML would result in a binding being established for the script property; i.e. script would be assigned the value obtained from running myObj.value = Math.max(myValue, 100)
MyType {
script: myObj.value = Math.max(myValue, 100)
}If instead the property had a type of QQmlScriptString, the script itself – myObj.value = Math.max(myValue, 100) – would be passed to the script property and the class could choose how to handle it. Typically, the class will evaluate the script at some later time using a QQmlExpression.
QQmlExpression expr(scriptString);

Member Function Documentation▲
QQmlScriptString::QQmlScriptString()▲
Constructs an empty instance.
QQmlScriptString::QQmlScriptString(const QQmlScriptString &other)▲
Copies other.
bool QQmlScriptString::booleanLiteral(bool *ok) const▲
If the content of the QQmlScriptString is a boolean literal, returns the boolean value and sets ok to true. Otherwise returns false and sets ok to false.
bool QQmlScriptString::isEmpty() const▲
Returns whether the QQmlScriptString is empty.
bool QQmlScriptString::isNullLiteral() const▲
Returns whether the content of the QQmlScriptString is the null literal.
bool QQmlScriptString::isUndefinedLiteral() const▲
Returns whether the content of the QQmlScriptString is the undefined literal.
qreal QQmlScriptString::numberLiteral(bool *ok) const▲
If the content of the QQmlScriptString is a number literal, returns that number and sets ok to true. Otherwise returns 0.0 and sets ok to false.
QString QQmlScriptString::stringLiteral() const▲
If the content of the QQmlScriptString is a string literal, returns that string. Otherwise returns a null QString.
bool QQmlScriptString::operator!=(const QQmlScriptString &other) const▲
Returns true if this and the other QQmlScriptString objects are different.
