No, uic is not extensible.

Yes, QDesigner supports only types it knows. However, the list of known types is quite large.


Taking into account that uic needs to convert an xml based property values into the C++ code, it wouldn't be easily possible without any plugin architecture / extension system of uic.

Hello，I want to add custom property type to the designer.

I'm trying to do that：


struct TestType
{
    int x;
    int y;
};
Q_DECLARE_METATYPE(TestType)

class ...
{
    Q_OBJECT
    Q_PROPERTY(TestType Test
               READ     Test
               WRITE    SetTest)
    ...
};


But the property do not appear in the designer.

Property type can only be Qt's own?(and Q_ENUM、Q_FLAGS)
