\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.PP
This function uses the QClipboard::clear() function which takes a QClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is QClipboard::Selection, otherwise the mode argument is QClipboard::Clipboard.
.SH "QMimeSource * QClipboard::data ( Mode mode ) const"
Returns a reference to a QMimeSource representation of the current clipboard data.
.PP
The \fImode\fR argument is used to control which part of the system clipboard is used. If \fImode\fR is QClipboard::Clipboard, the data is retreived from the global clipboard. If \fImode\fR is QClipboard::Selection, the data is retreived from the global mouse selection.
.PP
See also setData().
.SH "QMimeSource * QClipboard::data () const"
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.PP
This function uses the QClipboard::data() function which takes a QClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is QClipboard::Selection, otherwise the mode argument is QClipboard::Clipboard.
.SH "void QClipboard::dataChanged ()\fC [signal]\fR"
This signal is emitted when the clipboard data is changed.
.SH "QImage QClipboard::image ( Mode mode ) const"
Returns the clipboard image, or returns a null image if the clipboard does not contain an image or if it contains an image in an unsupported image format.
.PP
The \fImode\fR argument is used to control which part of the system clipboard is used. If \fImode\fR is QClipboard::Clipboard, the image is retreived from the global clipboard. If \fImode\fR is QClipboard::Selection, the image is retreived from the global mouse selection.
.PP
See also setImage(), pixmap(), data(), and QImage::isNull().
.SH "QImage QClipboard::image () const"
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.PP
This function uses the QClipboard::image() function which takes a QClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is QClipboard::Selection, otherwise the mode argument is QClipboard::Clipboard.
.SH "bool QClipboard::ownsClipboard () const"
Returns TRUE if this clipboard object owns the clipboard data; otherwise returns FALSE.
.SH "bool QClipboard::ownsSelection () const"
Returns TRUE if this clipboard object owns the mouse selection data; otherwise returns FALSE.
.SH "QPixmap QClipboard::pixmap ( Mode mode ) const"
Returns the clipboard pixmap, or null if the clipboard does not contain a pixmap. Note that this can lose information. For example, if the image is 24-bit and the display is 8-bit, the result is converted to 8 bits, and if the image has an alpha channel, the result just has a mask.
.PP
The \fImode\fR argument is used to control which part of the system clipboard is used. If \fImode\fR is QClipboard::Clipboard, the pixmap is retreived from the global clipboard. If \fImode\fR is QClipboard::Selection, the pixmap is retreived from the global mouse selection.
.PP
See also setPixmap(), image(), data(), and QPixmap::convertFromImage().
.SH "QPixmap QClipboard::pixmap () const"
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.PP
This function uses the QClipboard::pixmap() function which takes a QClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is QClipboard::Selection, otherwise the mode argument is QClipboard::Clipboard.
.SH "void QClipboard::selectionChanged ()\fC [signal]\fR"
This signal is emitted when the selection is changed. This only applies to windowing systems that support selections, e.g. X11. Windows doesn't support selections.
.SH "bool QClipboard::selectionModeEnabled () const"
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.PP
Use the QClipboard::data(), QClipboard::setData() and related functions which take a QClipboard::Mode argument.
.PP
Returns the selection mode.
.PP
See also setSelectionMode() and supportsSelection().
.SH "void QClipboard::setData ( QMimeSource * src, Mode mode )"
Sets the clipboard data to \fIsrc\fR. Ownership of the data is transferred to the clipboard. If you want to remove the data either call clear() or call setData() again with new data.
.PP
The \fImode\fR argument is used to control which part of the system clipboard is used. If \fImode\fR is QClipboard::Clipboard, the data is retreived from the global clipboard. If \fImode\fR is QClipboard::Selection, the data is retreived from the global mouse selection.
.PP
The QDragObject subclasses are reasonable objects to put into the clipboard (but do not try to call QDragObject::drag() on the same object). Any QDragObject placed in the clipboard should have a parent of 0. Do not put QDragMoveEvent or QDropEvent subclasses in the clipboard, as they do not belong to the event handler which receives them.
.PP
The setText(), setImage() and setPixmap() functions are simpler wrappers for setting text, image and pixmap data respectively.
.PP
See also data().
.SH "void QClipboard::setData ( QMimeSource * src )"
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.PP
This function uses the QClipboard::setData() function which takes a QClipboard::Mode argument. The value of the mode argument is determined by the return value of selectionModeEnabled(). If selectionModeEnabled() returns TRUE, the mode argument is QClipboard::Selection, otherwise the mode argument is QClipboard::Clipboard.
.SH "void QClipboard::setImage ( const QImage & image, Mode mode )"
Copies \fIimage\fR into the clipboard.
.PP
The \fImode\fR argument is used to control which part of the system clipboard is used. If \fImode\fR is QClipboard::Clipboard, the image is stored in the global clipboard. If \fImode\fR is QClipboard::Selection, the data is stored in the global mouse selection.
.PP
This is shorthand for:
.PP
.nf
.br
        setData( new QImageDrag(image), mode )
.br
.fi
.PP

If selectionModeEnabled() returns TRUE, the mode argument is QClipboard::Selection, otherwise the mode argument is QClipboard::Clipboard.
.SH "void QClipboard::setPixmap ( const QPixmap & pixmap, Mode mode )"
Copies \fIpixmap\fR into the clipboard. Note that this is slower than setImage() because it needs to convert the QPixmap to a QImage first.
.PP
The \fImode\fR argument is used to control which part of the system clipboard is used. If \fImode\fR is QClipboard::Clipboard, the pixmap is stored in the global clipboard. If \fImode\fR is QClipboard::Selection, the pixmap is stored in the global mouse selection.

.PP
Use the QClipboard::data(), QClipboard::setData() and related functions which take a QClipboard::Mode argument.
.PP
Sets the clipboard selection mode. If \fIenable\fR is TRUE, then subsequent calls to QClipboard::setData() and other functions which put data into the clipboard will put the data into the mouse selection, otherwise the data will be put into the clipboard.
.PP

.SH "void QClipboard::setText ( const QString & text, Mode mode )"
Copies \fItext\fR into the clipboard as plain text.
.PP
