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. If a settings application updates this variable it should send the message "updateAudibleScreenClick()" on the "QPE/System" channel to allow the value to be reread. Creating this class automatically enables the "AudibleScreenClick" QtopiaFeature.

This class is part of the Qt Extended server and cannot be used by other Qt Extended applications.
