properies and custom types
Message 1 in thread
I want to use property of my custom type.
1. I create 2 classes for my custom type (register by Q_METATYPE,
qRegisterMetaType)
simular to
class Type1 : public QObject
{
...
};
class Type2 : public QObject
{
Q_OBJECT
Q_PROPERTY (Type1 value READ value WRITE setValue)
public:
...
public slots:
Type1 value() const;
void setValue(const Type1&);
QString toString() const
{
return theValue.toString();
}
private:
Type1 theValue;
}
2. I create QSObjectFactory for creating my custom types and add it into
QSInterpreter
3. Then I use:
///////////////////////////
var variable1:Type1, variable2:Type2;
// init values
....
variable2.value = variable1;
System.println(variable2.toString());
variable1 = variable2.value;
System.println(variable1.toString());
/////////////////////////////
Values of Type1 are incorrect ...
What do I do wrong?

Hi Cepera,
There is a bug in QSA 1.2.1 which prevents custom registered metatypes
from working so you won't be able to do this with the current version.
Please note however that what you are doing is wrong in any case as you
are trying to use a QObject as a value type. This will crash, assert or
fail in some other way...

Instead of this I should use Type1 and Type2 (not QObject), and make wrapers
(QObject) for using my custom types in Qsa, is it right?

But wrappers are only for pointer types, so that won't work
unfortunatly. We are looking at how extension can be made smoother in
the next version of QSA.
