.SH DESCRIPTION
|
|
|
|
|
The QImageDrag class provides a drag and drop object for transferring images.
|
|
|
|
|
.PP
|
|
|
|
|
Images are offered to the receiving application in multiple formats, determined by Qt's output formats.
|
|
|
|
|
.PP
|
|
|
|
|
For more information about drag and drop, see the QDragObject class and the drag and drop documentation.

.SH MEMBER FUNCTION DOCUMENTATION
|
|
|
|
|
.SH "QImageDrag::QImageDrag ( TQImage image, TQWidget * dragSource = 0, const char * name = 0 )"
|
|
|
|
|
Constructs an image drag object and sets its data to \fIimage\fR. \fIdragSource\fR must be the drag source; \fIname\fR is the object name.
|
|
|
|
|
.SH "QImageDrag::QImageDrag ( TQWidget * dragSource = 0, const char * name = 0 )"
|
|
|
|
|
Constructs a default image drag object. \fIdragSource\fR must be the drag source; \fIname\fR is the object name.
|
|
|
|
|
.SH "QImageDrag::~QImageDrag ()"
|
|
|
|
|
Destroys the image drag object and frees up all allocated resources.
|
|
|
|
|
.SH "bool QImageDrag::canDecode ( const QMimeSource * e )\fC [static]\fR"
|
|
|
|
|
Returns TRUE if the information in mime source \fIe\fR can be decoded into an image; otherwise returns FALSE.
|
|
|
|
|
.PP
|
|
|
|
|
See also decode().
|
|
|
|
|
.PP
|
|
|
|
|
Example: desktop/desktop.cpp.
|
|
|
|
|
.SH "bool QImageDrag::decode ( const QMimeSource * e, TQImage & img )\fC [static]\fR"
|
|
|
|
|
Attempts to decode the dropped information in mime source \fIe\fR into \fIimg\fR. Returns TRUE if successful; otherwise returns FALSE.
|
|
|
|
|
.PP
|
|
|
|
|

|
|
|
.SH "bool QImageDrag::decode ( const QMimeSource * e, QPixmap & pm )\fC [static]\fR"
|
|
|
|
|
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
|
|
|
|
.PP
|
|
|
|
|
Attempts to decode the dropped information in mime source \fIe\fR into pixmap \fIpm\fR. Returns TRUE if successful; otherwise returns FALSE.
|
|
|
|
|
.PP
|
|
|
|
|
This is a convenience function that converts to a QPixmap via a TQImage.
|
|
|
|
|
.PP
|

|
|
See also canDecode().
|
|
|
|
|
.SH "void QImageDrag::setImage ( TQImage image )\fC [virtual]\fR"
|
|
|
|
|
Sets the image to be dragged to \fIimage\fR. You will need to call
|
|
|
|
|
this if you did not pass the image during construction.
