"""Demo program for ScrolledThumbnail widget.
:class:`ScrolledThumbnail` provides a scrollable window containing
thumbnail images. These thumbnails are provided to the widget in
an array of :class:`Thumb` objects. The images can be selected,
resized, or rotated. Optionally, tooltips can provide information
about the image file or popups can be displayed when a thumbnail is
selected.
The included :class:`Thumb` supports image files like JPEG, GIF, or
PNG, using either native Python or PIL functions. This class can
be extended by the user to support other types, for example, to
provide a thumbnail of a TXT or PDF file.
:class:`ScrolledThumbnail` is based on :class:`ThumbnailCtrl`, with
the difference that the latter is essentially an image browser
application, performing file operations as well as filtering and
sorting image files. :class:`ScrolledThumbnail` contains only the
support for displaying thumbnail images in a scrolling window, with
generating thumbnails, reading files, and other operations which
are not related to displaying the thumbnail to either the user of
the class (e.g., this demo), or to support classes such as
:class:`Thumb`.
For full documentation, see the comments in agw/scrolledthumbnail.py.
This class extends the common code in ThumbDemoConfig to work with
the :class:`ScrolledThumbnail` widget.
