# NOTE:
# This was written to provide a standard integer edit control for wxPython.
#
# IntCtrl permits integer (long) values to be retrieved or set via
# .GetValue() and .SetValue(), and provides an EVT_INT() event function
# for trapping changes to the control.
#
# It supports negative integers as well as the naturals, and does not
# permit leading zeros or an empty control; attempting to delete the
# contents of the control will result in a (selected) value of zero,
# thus preserving a legitimate integer value, or an empty control
# (if a value of None is allowed for the control.) Similarly, replacing the
# contents of the control with '-' will result in a selected (absolute)
# value of -1.
#
# IntCtrl also supports range limits, with the option of either
# enforcing them or simply coloring the text of the control if the limits
# are exceeded.

min
The minimum value that the control should allow. This can be
adjusted with SetMin(). If the control is not limited, any value
below this bound will be colored with the current out-of-bounds color.
If min < -sys.maxint-1 and the control is configured to not allow long
values, the minimum bound will still be set to the long value, but
the implicit bound will be -sys.maxint-1.
max
The maximum value that the control should allow. This can be
adjusted with SetMax(). If the control is not limited, any value
above this bound will be colored with the current out-of-bounds color.
if max > sys.maxint and the control is configured to not allow long
values, the maximum bound will still be set to the long value, but
the implicit bound will be sys.maxint.
limited
Boolean indicating whether the control prevents values from
exceeding the currently set minimum and maximum values (bounds).
If False and bounds are set, out-of-bounds values will
be colored with the current out-of-bounds color.
allow_none
Boolean indicating whether or not the control is allowed to be
empty, representing a value of None for the control.
allow_long
Boolean indicating whether or not the control is allowed to hold
and return a long as well as an int.
default_color
Color value used for in-bounds values of the control.
oob_color
Color value used for out-of-bounds values of the control
when the bounds are set but the control is not limited.

Normally None, IntCtrl uses its own validator to do value
validation and input control. However, a validator derived
