"""Demo program for ThumbnailCtrl widget.
:class:`ThumbnailCtrl` provides an image browser widget in a
scrollable window containing thumbnail images. The class reads
the specified directory, filters by image type, and create
thumbnail images. The images can be selected, resized, or rotated.
Files can be deleted. 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.
:class:`ScrolledThumbnail` is used by :class:`ThumbnailCtrl`, to
provide the scrolling thumbnail window. Many of the methods of
:class:`ThumbnailCtrl` are actually delegated to
:class:`ScrolledThumbnail`.
For full documentation, see the comments in agw/thumbnailctrl.py.
This class extends the common code in ThumbDemoConfig to work with
the :class:`ThumbnailCtrl` widget.
