<P>
<B>wxTimeCtrl</B> provides a multi-cell control that allows manipulation of a time value. It supports 12 or 24 hour format, and you can use wxDateTime or mxDateTimet o get/set values from the control.
<P>
Left/right/tab keys to switch cells within a wxTimeCtrl, and the up/down arrows act like a spin control. wxTimeCtrl also allows for an actual spin button to be attached to the control, so that it acts like the up/down arrow keys.
<P>
Here's the interface for wxTimeCtrl:
<DL>
<PRE>
<B>wxTimeCtrl</B>(parent, id = -1,
<B>value</B> = '12:00:00 AM',
pos = wxDefaultPosition,
size = wxDefaultSize,
<B>fmt24hr</B> = false,
<B>spinButton</B> = None,
<B>style</B> = wxTE_PROCESS_TAB,
name = "time")
</PRE>
<UL>
<DT><B>value</B><DD>If no initial value is set, the default will be midnight; if an illegal string is specified, a ValueError will result. (You can always later set the initial time with SetValue() after instantiation of the control.)
<DL><B>size</B><DD>The size of the control will be automatically adjusted for 12/24 hour format if wxDefaultSize is specified.
<DT><B>fmt24hr</B><DD>If true, control will display time in 24 hour time format; if false, it will use 12 hour AM/PM format. SetValue() will adjust values accordingly for the control, based on the format specified.
<DT><B>spinButton</B><DD>If specified, this button's events will be bound to the behavior of the wxTimeCtrl, working like up/down cursor key events. (See BindSpinButton.)
<DT><B>style</B><DD>By default, wxTimeCtrl will process TAB events, by allowing tab to the different cells within the control.
</DL>
</UL>
<DT><B>SetValue(time_string)</B><DD>Sets the value of the control to a particular time, given a valid time string; raises ValueError on invalid value
<DT><B>GetValue()</B><DD>Retrieves the string value of the time from the control
<BR>
<DT><B>SetWxDateTime(wxDateTime)</B><DD>Uses the time portion of a wxDateTime to construct a value for the control.
<DT><B>GetWxDateTime()</B><DD>Retrieves the value of the control, and applies it to the wxDateTimeFromHMS() constructor, and returns the resulting value. (This returns the date portion as "today".)
<BR>
<DT><B>SetMxDateTime(mxDateTime)</B><DD>Uses the time portion of an mxDateTime to construct a value for the control. <EM>NOTE:</EM> This imports mx.DateTime at runtime only if this or the Get function is called.
<DT><B>GetMxDateTime()</B><DD>Retrieves the value of the control and applies it to the DateTime.Time() constructor, and returns the resulting value. (mxDateTime is smart enough to know this is just a time value.)
<BR>
<DT><B>BindSpinButton(wxSpinBtton)</B><DD>Binds an externally created spin button to the control, so that up/down spin events change the active cell or selection in the control (in addition to the up/down cursor keys.) (This is primarily to allow you to create a "standard" interface to time controls, as seen in Windows.)
<BR>
<DT><B>EVT_TIMEUPDATE(win, id, func)</B><DD>func is fired whenever the value of the control changes.
</DL>

# NOTE:
# This was written way it is because of the lack of masked edit controls
# in wxWindows/wxPython. I would also have preferred to derive this
# control from a wxSpinCtrl rather than wxTextCtrl, but the wxTextCtrl
# component of that control is inaccessible through the interface exposed in
# wxPython.
#
# wxTimeCtrl does not use validators, because it does careful manipulation
# of the cursor in the text window on each keystroke, and validation is
# cursor-position specific, so the control intercepts the key codes before the
# validator would fire.
