16 The QFilePreview class provides file previewing in QFileDialog.
17
18 This class is an abstract base class which is used to implement widgets
19 that can display a preview of a file in a QFileDialog.
20
21 You must derive the preview widget from both QWidget and from this
22 class. Then you must reimplement this class's previewUrl() function,
23 which is called by the file dialog if the preview of a file (specified
24 as a URL) should be shown.

40 This function is called by QFileDialog if a preview for the url should
41 be shown. Reimplement this function to provide file previewing.
