Descripción detallada

The QTextDrag class is a drag and drop object for transferring plain and Unicode text.

Plain text is passed in a QString which may contain multiple lines (i.e. may contain newline characters). The drag target will receive the newlines according to the runtime environment, e.g. LF on Unix, and CRLF on Windows.

Qt provides no built-in mechanism for delivering only a single-line.

For more information about drag and drop, see the QDragObject class and the drag and drop documentation.

Documentación del constructor y destructor

QTextDrag::QTextDrag	(	const QString &	text,
		QWidget *	dragSource = 0,
		const char *	name = 0
	)

Constructs a text drag object and sets its data to text. dragSource must be the drag source; name is the object name.

QTextDrag::QTextDrag	(	QWidget *	dragSource = 0,
		const char *	name = 0
	)

Constructs a default text drag object. dragSource must be the drag source; name is the object name.

QTextDrag::~QTextDrag

(

)

Destroys the text drag object and frees up all allocated resources.

QTextDrag::QTextDrag	(	const QString &	,
		QWidget *	dragSource = 0,
		const char *	name = 0
	)

QTextDrag::QTextDrag	(	QWidget *	dragSource = 0,
		const char *	name = 0
	)

QTextDrag::~QTextDrag

canDecode()

bool QTextDrag::decode	(	const QMimeSource *	e,
		QString &	str,
		QCString &	subtype
	)		[static]

Esta es una función miembro sobrecargada que se suministra por conveniencia. Difiere de la anterior función solamente en los argumentos que acepta. Attempts to decode the dropped information in e into str. Returns TRUE if successful; otherwise returns FALSE. If subtype is null, any text subtype is accepted; otherwise only the specified subtype is accepted.

virtual void QTextDrag::setSubtype

(

const QCString &

)

[virtual]

void QTextDrag::setSubtype

(

const QCString &

st

)

[virtual]

Sets the MIME subtype of the text being dragged to st. The default subtype is "plain", so the default MIME type of the text is "text/plain". You might use this to declare that the text is "text/html" by calling setSubtype("html").

virtual void QTextDrag::setText

(

const QString &

)

[virtual]

void QTextDrag::setText

(

const QString &

text

)

[virtual]

Sets the text to be dragged to text. You will need to call this if you did not pass the text during construction.
