Member Function Documentation

AttachDataFile

void DdtViewer::AttachDataFile ( QString  filename )

signal

Signal that sends a filename of a file to open

Parameters

filename

filename and path of the file to open at startup

AttachDataStream

void DdtViewer::AttachDataStream ( QString  data_stream )

signal

Signal that sends a stream URI to the image widget

Parameters

connect() [1/4]

void DdtViewer::connect	(	const QObject *	sender,
		const char *	signal,
		const char *	member
	)

connect() [2/4]

void DdtViewer::connect	(	const QObject *	sender,
		const char *	signal,
		const QObject *	receiver,
