/** the beginner's hex edit widget ;)
*
* It hides the concept of the KDataBuffer and accepts a pure pointer
* to a reasonable large array of bytes
*
* 1. used as viewer
* a) static data ranges -> no changes for data pointer and length
* possible changes are told to the widget by repaintRange
* b) changing data ranges -> data pointer and length might change
* changes told by
* * resetData( char *, int size, bool tqrepaint );
* *
* 2. used as editor
* a) static data ranges
* data pointer stays the same
* b) changing data ranges
* pointer to the data changes in charge of the widget:
* given pointer and intermediate pointer are possibly invalid
* problem: who cares about the array if the data is deleted?
* -> solved by setAutoDelete()
