Buffer Backends

These are the available buffer backends:

• QMemoryBuffer: A simple, flat memory array.
• QMemoryRefBuffer: QHexView just display the referenced data, editing is disabled.
  

Usage

The data is managed by QHexView through QHexDocument class.
You can load a generic QIODevice using the method fromDevice() of QHexDocument class with various buffer backends.
Helper methods are provided in order to load a QFile a In-Memory buffer in QHexView:

// Load data from In-Memory Buffer...
QHexDocument* document = QHexDocument::fromMemory<QMemoryBuffer>(bytearray);
// ...from a generic I/O device...
QHexDocument* document = QHexDocument::fromDevice<QMemoryBuffer>(iodevice);
/* ...or from File */
QHexDocument* document = QHexDocument::fromFile<QMemoryBuffer>("data.bin");

QHexView* hexview = new QHexView();
hexview->setDocument(document);                  // Associate QHexEditData with this QHexEdit

// Document editing
QByteArray data = document->read(24, 78);        // Read 78 bytes starting to offset 24
document->insert(4, "Hello QHexEdit");           // Insert a string to offset 4 
document->remove(6, 10);                         // Delete bytes from offset 6 to offset 10 
document->replace(30, "New Data");               // Replace bytes from offset 30 with the string "New Data"

// Metatadata management
QHexMetadata* hexmetadata = document->metadata();

hexmetadata->background(6, 0, 10, Qt::Red);      // Highlight background to line 6, from 0 to 10 
hexmetadata->foreground(8, 0, 15, Qt::darkBLue); // Highlight foreground to line 8, from 0 to 15
hexmetadata->comment(16, "I'm a comment!");      // Add a comment to line 16
hexmetadata->clear();                            // Reset styling
