QMimeSource(3qt) QMimeSource(3qt) NAME
QMimeSource - Abstraction of objects which provide formatted data of a certain MIME type SYNOPSIS
#include <qmime.h> Inherited by QDragObject and QDropEvent. Public Members QMimeSource () virtual ~QMimeSource () virtual const char * format ( int i = 0 ) const = 0 virtual bool provides ( const char * mimeType ) const virtual QByteArray encodedData ( const char * ) const = 0 int serialNumber () const DESCRIPTION
The QMimeSource class is an abstraction of objects which provide formatted data of a certain MIME type. Drag-and-drop and clipboard use this abstraction. See also IANA list of MIME media types, Drag And Drop Classes, Input/Output and Networking, and Miscellaneous Classes. MEMBER FUNCTION DOCUMENTATION
QMimeSource::QMimeSource () Constructs a mime source and assigns a globally unique serial number to it. See also serialNumber(). QMimeSource::~QMimeSource () [virtual] Provided to ensure that subclasses destroy themselves correctly. QByteArray QMimeSource::encodedData ( const char * ) const [pure virtual] Returns the encoded data of this object in the specified MIME format. Subclasses must reimplement this function. Reimplemented in QStoredDrag, QDropEvent, and QIconDrag. const char * QMimeSource::format ( int i = 0 ) const [pure virtual] Returns the i-th supported MIME format, or 0. Reimplemented in QDropEvent. bool QMimeSource::provides ( const char * mimeType ) const [virtual] Returns TRUE if the object can provide the data in format mimeType; otherwise returns FALSE. If you inherit from QMimeSource, for consistency reasons it is better to implement the more abstract canDecode() functions such as QTextDrag::canDecode() and QImageDrag::canDecode(). Example: iconview/simple_dd/main.cpp. Reimplemented in QDropEvent. int QMimeSource::serialNumber () const Returns the mime source's globally unique serial number. SEE ALSO

QImageDrag(3qt) QImageDrag(3qt) NAME
QImageDrag - Drag and drop object for transferring images SYNOPSIS
#include <qdragobject.h> Inherits QDragObject. Public Members QImageDrag ( QImage image, QWidget * dragSource = 0, const char * name = 0 ) QImageDrag ( QWidget * dragSource = 0, const char * name = 0 ) ~QImageDrag () virtual void setImage ( QImage image ) Static Public Members bool canDecode ( const QMimeSource * e ) bool decode ( const QMimeSource * e, QImage & img ) bool decode ( const QMimeSource * e, QPixmap & pm ) DESCRIPTION
The QImageDrag class provides a drag and drop object for transferring images. Images are offered to the receiving application in multiple formats, determined by Qt's output formats. For more information about drag and drop, see the QDragObject class and the drag and drop documentation. See also Drag And Drop Classes. MEMBER FUNCTION DOCUMENTATION
QImageDrag::QImageDrag ( QImage image, QWidget * dragSource = 0, const char * name = 0 ) Constructs an image drag object and sets its data to image. dragSource must be the drag source; name is the object name. QImageDrag::QImageDrag ( QWidget * dragSource = 0, const char * name = 0 ) Constructs a default image drag object. dragSource must be the drag source; name is the object name. QImageDrag::~QImageDrag () Destroys the image drag object and frees up all allocated resources. bool QImageDrag::canDecode ( const QMimeSource * e ) [static] Returns TRUE if the information in mime source e can be decoded into an image; otherwise returns FALSE. See also decode(). Example: desktop/desktop.cpp. bool QImageDrag::decode ( const QMimeSource * e, QImage & img ) [static] Attempts to decode the dropped information in mime source e into img. Returns TRUE if successful; otherwise returns FALSE. See also canDecode(). Example: desktop/desktop.cpp. bool QImageDrag::decode ( const QMimeSource * e, QPixmap & pm ) [static] This is an overloaded member function, provided for convenience. It behaves essentially like the above function. Attempts to decode the dropped information in mime source e into pixmap pm. Returns TRUE if successful; otherwise returns FALSE. This is a convenience function that converts to a QPixmap via a QImage. See also canDecode(). void QImageDrag::setImage ( QImage image ) [virtual] Sets the image to be dragged to image. You will need to call this if you did not pass the image during construction. SEE ALSO
