Detailed Description

The ScreenClick class enables an audible clicking sound whenever the stylus is used.

The ScreenClick class is not a true task. Instead, a real task should derive from the ScreenClick baseclass and implement the ScreenClick::screenClick() virtual method.

For example, an implementation may look like this:

    class MyScreenClick : public ScreenClick
    {
    protected:
        virtual void screenClick(bool pressed)
        {
            // Make click noise
        }
    };
    QTOPIA_TASK(MyScreenClick, MyScreenClick);

Screen clicking will only occur when the Trolltech/Sound/System/Touch configuration variable is true, otherwise ScreenClick::screenClick() will not be called. Creating this class automatically enables the "AudibleScreenClick" QtopiaFeature.
