+<P>
+<B>wxIntCtrl</B> provides a control that takes and returns integers as
+value, and provides bounds support and optional value limiting.
+<P>
+<P>
+Here's the API for wxIntCtrl:
+<DL><PRE>
+ <B>wxIntCtrl</B>(
+ parent, id = -1,
+ <B>value</B> = 0,
+ <B>min</B> = None,
+ <B>max</B> = None,
+ <B>limited</B> = False,
+ <B>allow_none</B> = False,
+ <B>allow_long</B> = False,
+ <B>default_color</B> = wxBLACK,
+ <B>oob_color</B> = wxRED,
+ pos = wxDefaultPosition,
+ size = wxDefaultSize,
+ style = 0,
+ name = "integer")
+</PRE>
+<UL>
+ <DT><B>value</B>
+ <DD>If no initial value is set, the default will be zero, or
+ the minimum value, if specified. If an illegal string is specified,
+ a ValueError will result. (You can always later set the initial
+ value with SetValue() after instantiation of the control.)
+ <BR>
+ <DL><B>min</B>
+ <DD>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.
+ <BR>
+ <DT><B>max</B>
+ <DD>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.
+ <BR>
+ <DT><B>limited</B>
+ <DD>Boolean indicating whether the control prevents values from
+ exceeding the currently set minimum and maximum values (bounds).
+ If <I>False</I> and bounds are set, out-of-bounds values will
+ be colored with the current out-of-bounds color.
+ <BR>
+ <DT><B>allow_none</B>
+ <DD>Boolean indicating whether or not the control is allowed to be
+ empty, representing a value of <I>None</I> for the control.
+ <BR>
+ <DT><B>allow_long</B>
+ <DD>Boolean indicating whether or not the control is allowed to hold
+ and return a value of type long as well as int. If False, the
+ control will be implicitly limited to have a value such that
+ -sys.maxint-1 <= n <= sys.maxint.
+ <BR>
+ <DT><B>default_color</B>
+ <DD>Color value used for in-bounds values of the control.
+ <BR>
+ <DT><B>oob_color</B>
+ <DD>Color value used for out-of-bounds values of the control
+ when the bounds are set but the control is not limited.
+</UL>
+<BR>
+<BR>
+<DT><B>EVT_INT(win, id, func)</B>
+<DD>Respond to a wxEVT_COMMAND_INT_UPDATED event, generated when the
+value changes. Notice that this event will always be sent when the
+control's contents changes - whether this is due to user input or
+comes from the program itself (for example, if SetValue() is called.)
+<BR>
+<BR>
+<DT><B>SetValue(int)</B>
+<DD>Sets the value of the control to the integer value specified.
+The resulting actual value of the control may be altered to
+conform with the bounds set on the control if limited,
+or colored if not limited but the value is out-of-bounds.
+A ValueError exception will be raised if an invalid value
+is specified.
+<BR>
+<DT><B>GetValue()</B>
+<DD>Retrieves the integer value from the control. The value
+retrieved will be sized as an int if possible or a long,
+if necessary.
+<BR>
+<BR>
+<DT><B>SetMin(min=None)</B>
+<DD>Sets the expected minimum value, or lower bound, of the control.
+(The lower bound will only be enforced if the control is
+configured to limit its values to the set bounds.)
+If a value of <I>None</I> is provided, then the control will have
+no explicit lower bound. If the value specified is greater than
+the current lower bound, then the function returns 0 and the
+lower bound will not change from its current setting. On success,
+the function returns 1.
+<DT><DD>If successful and the current value is
+lower than the new lower bound, if the control is limited, the
+value will be automatically adjusted to the new minimum value;
+if not limited, the value in the control will be colored with
+the current out-of-bounds color.
+<BR>
+<DT><B>GetMin()</B>
+<DD>Gets the current lower bound value for the control.
+It will return None if no lower bound is currently specified.
+<BR>
+<BR>
+<DT><B>SetMax(max=None)</B>
+<DD>Sets the expected maximum value, or upper bound, of the control.
+(The upper bound will only be enforced if the control is
+configured to limit its values to the set bounds.)
+If a value of <I>None</I> is provided, then the control will
+have no explicit upper bound. If the value specified is less
+than the current lower bound, then the function returns 0 and
+the maximum will not change from its current setting. On success,
+the function returns 1.
+<DT><DD>If successful and the current value
+is greater than the new upper bound, if the control is limited
+the value will be automatically adjusted to the new maximum value;
+if not limited, the value in the control will be colored with the
+current out-of-bounds color.
+<BR>
+<DT><B>GetMax()</B>
+<DD>Gets the current upper bound value for the control.
+It will return None if no upper bound is currently specified.
+<BR>
+<BR>
+<DT><B>SetBounds(min=None,max=None)</B>
+<DD>This function is a convenience function for setting the min and max
+values at the same time. The function only applies the maximum bound
+if setting the minimum bound is successful, and returns True
+only if both operations succeed. <B><I>Note:</I></B> leaving out an argument
+will remove the corresponding bound.
+<DT><B>GetBounds()</B>
+<DD>This function returns a two-tuple (min,max), indicating the
+current bounds of the control. Each value can be None if
+that bound is not set.
+<BR>
+<BR>
+<DT><B>IsInBounds(value=None)</B>
+<DD>Returns <I>True</I> if no value is specified and the current value
+of the control falls within the current bounds. This function can also
+be called with a value to see if that value would fall within the current
+bounds of the given control.
+<BR>
+<BR>
+<DT><B>SetLimited(bool)</B>
+<DD>If called with a value of True, this function will cause the control
+to limit the value to fall within the bounds currently specified.
+If the control's value currently exceeds the bounds, it will then
+be limited accordingly.
+If called with a value of 0, this function will disable value
+limiting, but coloring of out-of-bounds values will still take
+place if bounds have been set for the control.
+<DT><B>IsLimited()</B>
+<DD>Returns <I>True</I> if the control is currently limiting the
+value to fall within the current bounds.
+<BR>
+<BR>
+<DT><B>SetNoneAllowed(bool)</B>
+<DD>If called with a value of True, this function will cause the control
+to allow the value to be empty, representing a value of None.
+If called with a value of fakse, this function will prevent the value
+from being None. If the value of the control is currently None,
+ie. the control is empty, then the value will be changed to that
+of the lower bound of the control, or 0 if no lower bound is set.
+<DT><B>IsNoneAllowed()</B>
+<DD>Returns <I>True</I> if the control currently allows its
+value to be None.
+<BR>
+<BR>
+<DT><B>SetLongAllowed(bool)</B>
+<DD>If called with a value of True, this function will cause the
+control to allow the value to be a long. If called with a value
+of False, and the value of the control is currently a long value,
+the value of the control will be adjusted to fall within the
+size of an integer type, at either the sys.maxint or -sys.maxint-1,
+for positive and negative values, respectively.
+<DT><B>IsLongAllowed()</B>
+<DD>Returns <I>True</I> if the control currently allows its
+value to be of type long.
+<BR>
+<BR>
+<DT><B>SetColors(default_color=wxBLACK, oob_color=wxRED)</B>
+<DD>Tells the control what colors to use for normal and out-of-bounds
+values. If the value currently exceeds the bounds, it will be
+recolored accordingly.
+<DT><B>GetColors()</B>
+<DD>Returns a tuple of <I>(default_color, oob_color)</I> indicating
+the current color settings for the control.
+<BR>
+<BR>
+<DT><B>Cut()</B>
+<DD>Will allow cuts to the clipboard of the text portion of the value,
+leaving the value of zero if the entire contents are "cut."
+<DT><B>Paste()</B>
+<DD>Will paste the contents of the clipboard to the selected portion
+of the value; if the resulting string does not represent a legal
+value, a ValueError will result. If the result is out-of bounds,
+it will either be adjusted or colored as appropriate.
