The TQFilePreview class provides file previewing in < a href = "ntqfiledialog.html" > TQFileDialog< / a > .
< p > This class is an abstract base class which is used to implement
widgets that can display a preview of a file in a TQFileDialog.
< p > You must derive the preview widget from both < a href = "ntqwidget.html" > TQWidget< / a > and from this
class. Then you must reimplement this class's < a href = "#previewUrl" > previewUrl< / a > () function,
which is called by the file dialog if the preview of a file
(specified as a URL) should be shown.
< p > See also < a href = "ntqfiledialog.html#setPreviewMode" > TQFileDialog::setPreviewMode< / a > (), < a href = "ntqfiledialog.html#setContentsPreview" > TQFileDialog::setContentsPreview< / a > (),
< a href = "ntqfiledialog.html#setInfoPreview" > TQFileDialog::setInfoPreview< / a > (), < a href = "ntqfiledialog.html#setInfoPreviewEnabled" > TQFileDialog::setInfoPreviewEnabled< / a > (),
< a href = "ntqfiledialog.html#setContentsPreviewEnabled" > TQFileDialog::setContentsPreviewEnabled< / a > ().
< p > For an example of a preview widget see qt/examples/qdir/qdir.cpp.
