QFilePreview(3qt)QFilePreview(3qt)NAMEQFilePreview - File previewing in QFileDialog
SYNOPSIS
#include <qfiledialog.h>
Public Members
QFilePreview ()
virtual void previewUrl ( const QUrl & url ) = 0
DESCRIPTION
The QFilePreview class provides file previewing in QFileDialog.
This class is an abstract base class which is used to implement widgets
that can display a preview of a file in a QFileDialog.
You must derive the preview widget from both QWidget and from this
class. Then you must reimplement this class's previewUrl() function,
which is called by the file dialog if the preview of a file (specified
as a URL) should be shown.
See also QFileDialog::setPreviewMode(),
QFileDialog::setContentsPreview(), QFileDialog::setInfoPreview(),
QFileDialog::setInfoPreviewEnabled(),
QFileDialog::setContentsPreviewEnabled().
For an example of a preview widget see qt/examples/qdir/qdir.cpp.
