Detailed 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. +

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. +

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. +

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. +

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. + + +
