//! The KeyboardSql class provides a key to layout convertion.
/*!
The KeyboardSql class is an database interface for a virtual keyboard.
It can manage different layouts, standard is a windows keyboard layout. Over
two functions, getKeyLayout() and getModifierLayout() it converts an unicode
char or a given id into different layout values like coordinates, color and
form data.
