The Q3FilePreview class provides file previewing in Q3FileDialog.
This class is an abstract base class which is used to implement widgets that can display a preview of a file in a Q3FileDialog.
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 Q3FileDialog::setPreviewMode(), Q3FileDialog::setContentsPreview(), Q3FileDialog::setInfoPreview(), Q3FileDialog::setInfoPreviewEnabled(), Q3FileDialog::setContentsPreviewEnabled().
Constructs the Q3FilePreview.
Destroys the file preview object.
This function is called by Q3FileDialog if a preview for the url should be shown. Reimplement this function to provide file previewing.
