<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,

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 false, 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.
