Protected class members are not accessible to subclasses

[GoogleCodeExporter]

I encountered this problem when trying to reimplement an event handler in a
class derived from QWidget and to call the base class implementation in it.
But event handler functions are not accessible, or any other protected
member functions. There should be some way for subclasses to call those
functions. 

What steps will reproduce the problem?

Here is a simple example which doesn't make much sense, but should still be
runnable (assumming that bindings would have all the methods from Qt classes). 

Run the following code with qs_eval : 

function A()
{
    QWidget.call(this);

    // test calling any protected method of QWidget
    this.resetInputContext();
}

A.prototype = new QWidget();

a = new A();

What is the expected output? What do you see instead?

Uncaught exception at ...: ReferenceError: resetInputContext is not defined

What version of the product are you using? On what operating system?
