H. Kossebau <Friedrich.W.H@Kossebau.de> + + +description: +----------- +The lib is the main work of KHexEdit2. It offers +a general usable hex edit widget "KHexEdit" +that interacts with an abstract data buffer +interface called "KDataBuffer". This interface can +be subclassed to offer access to different data buffers +like paged gigabyte big files, video memory or whatever +you can imagine (hopefully). + +For those simply needing a widget for a plain array of bytes +there is the widget subclass "KBytesEdit", which hides the +databuffer interface and publically simply interacts with +arrays (like "char Array[25];"). + + +installing: +----------- +As these widgets and the databuffer interface have not got +much testing the API might not be finished. Because of that +it won't be made public available, i.e. there will be no headers +installed. + + +usage: +------ +This lib is by now only used by the KBytesEdit part, to be found +in "../parts/kbytesedit". +It is _not_ used by the current KHexEdit 1 app. This will change once +the successor app from KHexEdit2 is done.
