Detailed Description

The beWavedDolphin clipboard layer: cell ↔ stream mapping plus the system clipboard transport (MIME wrapping and the versioned data header).

copy()/paste() are the pure data mapping between a SignalModel and a QDataStream (no simulation — the controller's slots own that). copyToClipboard()/ pasteFromClipboard() add the transport: the application MIME type, the legacy MIME type accepted on paste, and the versioned Serialization header. Cell values are stored relative to the selection's top-left so they can be re-anchored on paste.

Function Documentation

◆ copy()

void DolphinClipboard::copy	(	const SignalModel &	model,
		const QItemSelection &	ranges,
		QDataStream &	stream )

Serializes the values of the cells in ranges to stream (offsets relative to the selection's top-left).

◆ copyToClipboard()

void DolphinClipboard::copyToClipboard	(	const SignalModel &	model,
		const QItemSelection &	ranges )

Serializes the cells in ranges (with the versioned header) and places them on the system clipboard under the beWavedDolphin MIME type. ranges must be non-empty.

◆ firstColumn()

int DolphinClipboard::firstColumn	(	const SignalModel &	model,
		const QItemSelection &	ranges )

Returns the leftmost column index in ranges (clamped to the model's columns).

◆ firstRow()

int DolphinClipboard::firstRow	(	const SignalModel &	model,
		const QItemSelection &	ranges )

Returns the topmost row index in ranges (clamped to the model's rows).

◆ paste()

void DolphinClipboard::paste	(	SignalModel &	model,
		const QItemSelection &	ranges,
		QDataStream &	stream )

Deserializes cells from stream into model, anchored at the top-left of ranges. Cells landing outside the input rows or past the last column are silently dropped.

◆ pasteFromClipboard()

bool DolphinClipboard::pasteFromClipboard	(	SignalModel &	model,
		const QItemSelection &	ranges )

Reads beWavedDolphin waveform data from the system clipboard (current or legacy MIME type) and pastes it into model anchored at the top-left of ranges. Returns true iff the clipboard held waveform data that was applied.
