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 runningmyObj.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 thescript
property and the class could choose how to handle it. Typically, the class will evaluate the script at some later time using aQQmlExpression
.QQmlExpression expr(scriptString); expr.evaluate();

If the content of the
QQmlScriptString
is a boolean literal, returns the boolean value and setsok
to true. Otherwise returns false and setsok
to false.- isEmpty()¶
- Return type:
bool
Returns whether the

is empty.- isNullLiteral()¶
- Return type:
bool
Returns whether the content of the
QQmlScriptString
is thenull
literal.- isUndefinedLiteral()¶
- Return type:
bool
Returns whether the content of the
QQmlScriptString
is theundefined
literal.- numberLiteral()¶

to true. Otherwise returns 0.0 and setsok
to false.- __ne__(arg__1)¶
- Parameters:
arg__1 –
