# Name: wx.lib.mixins.inspection
# Purpose: A mix-in class that can add PyCrust-based inspection of the
# app's widgets and sizers.

class InspectionMixin(object):
"""
This class is intended to be used as a mix-in with the wx.App
class. When used it will add the ability to popup a
InspectionFrame window where the widget under the mouse cursor
will be selected in the tree and loaded into the shell's namespace
as 'obj'. The default key sequence to activate the inspector is
Ctrl-Alt-I (or Cmd-Alt-I on Mac) but this can be changed via
parameters to the `Init` method, or the application can call
`ShowInspectionTool` from other event handlers if desired.
To use this class simply derive a class from wx.App and
InspectionMixin and then call the `Init` method from the app's
OnInit.
