Macro Q_PROPERTY in child class

Gianluca86

Hi everyone, I have a question about the macro "Q_PROPERTY".

Example:

class ClassA: public QObject
{
    Q_OBJECT
    Q_PROPERTY(int Width READ GetWidth WRITE SetWidth)
    Q_PROPERTY(int Height READ GetHeight WRITE SetHeight)
...
}


class SubClassA: public ClassA
{
    Q_OBJECT
...
}
class SubClassB: public ClassA
{
    Q_OBJECT
...
}
class SubClassC: public ClassA
{
    Q_OBJECT
...
}

I know that the child classes inherit their father's property (so they will have the width and height properties).
If I wanted the subclass C had as a property only the width, there is a way to "hide" the other property?

These properties are displayed on a table.
I hope I explained myself.
Thank

no, such feature doesn't exist yet.
You can set the Q_PROPERTY to FINAL to mark it as non-overwritable.

The presence of the FINAL attribute indicates that the property will not be overridden by a derived class. This can be used for performance optimizations in some cases, but is not enforced by moc. Care must be taken never to override a FINAL property.

But this won't help you either.

Hi,
you can put just the width property to the base class (ClassA) and add the height property in the sub classes (SubClassA and B) where they are needed.

I understood, thanks.
@m-sue : That's not a nice way, but I'll use it.

Thanks to both.
