- Customizable data backend (see more below).
- Document/View based.
- Unlimited Undo/Redo.
- Fully Customizable.
- Fast rendering.
- Easy to Use.
Buffer Backends
These are the available buffer backends:
- QMemoryBuffer: A simple, flat memory array.
- QMemoryRefBuffer: QHexView just display the referenced data, editing is disabled.<br> <br>
It's also possible to create new data backends from scratch.
Usage
The data is managed by QHexView through QHexDocument class.<br> You can load a generic QIODevice using the method fromDevice() of QHexDocument class with various buffer backends.<br> Helper methods are provided in order to load a QFile a In-Memory buffer in QHexView:<br>
// 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, 0, 16, "I'm a comment!"); // Add a comment to line 16, from 0 to 16
hexmetadata->clear(); // Reset styling
