|
|
|
|
: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.
