# o Added a splitter between file list and view pane
# o Made directory path editable
# o Added an "up" button" to go to the parent dir
# o Changed to show directories in file list
# o Don't select images on double click any more
# o Added a 'broken image' display for files that wx fails to identify
# o Redesigned appearance -- using bitmap buttons now, and rearranged things
# o Fixed display of masked gifs
# o Fixed zooming logic to show shrunken images at correct aspect ratio
# o Added different background modes for preview (white/grey/dark/checkered)
# o Added framing modes for preview (no frame/box frame/tinted border)
#

This module provides the :class:`~lib.imagebrowser.ImageDialog` which allows to view and select
an image.


Description
===========

The :class:`wx.ImageDialog` allows the user to view images and select one.

Usage
=====

A simple usage would be::

    import wx
    import wx.lib.mixins.inspection as wit
    import wx.lib.imagebrowser as ib

    app = wit.InspectableApp()

    with ib.ImageDialog(None) as dlg:
        if dlg.ShowModal() == wx.ID_OK:
            # show the selected file
            print("You Selected File: " + dlg.GetFile())
        else:
            print("You pressed Cancel")

    app.MainLoop()
