|
||||
<P>
|
||||
The <B>timefield</B> command creates an enhanced text entry widget for
|
||||
the purpose of time entry with various degrees of built-in intelligence.
|
||||
</pre>
|
||||
|
||||
</pre><H2>METHODS</H2>
|
||||
<P>
|
||||
The <B>timefield</B> command creates a new Tcl command whose
|
||||
name is <I>pathName</I>. This
|
||||
command may be used to invoke various
|
||||
operations on the widget. It has the following general form:
|
||||
<pre>
|
||||
<I>pathName option </I>?<I>arg arg ...</I>?
|
||||
</pre>
|
||||
<I>Option</I> and the <I>arg</I>s
|
||||
determine the exact behavior of the command. The following
|
||||
commands are possible for timefield widgets:
|
||||
</pre><H2>WIDGET-SPECIFIC METHODS</H2>
|
||||
<DL>
|
||||
<DT> <I>pathName <B>cget</B> <I>option</I>
|
||||
</I></B>
|
||||
<DD> Returns the current value of the configuration option given
|
||||
by <I>option</I>.
|
||||
<I>Option</I> may have any of the values accepted by the <B>timefield</B>
|
||||
command.
|
||||
</DL>
|
||||
<DL>
|
||||
<DT> <I>pathName</I> <B>configure</B> ?<I>option</I>? ?<I>value option value ...</I>?
|
||||
</I></B>
|
||||
<DD> Query or modify the configuration options of the widget.
|
||||
If no <I>option</I> is specified, returns a list describing all of
|
||||
the available options for <I>pathName</I> (see <B>Tk_ConfigureInfo</B> for
|
||||
information on the format of this list). If <I>option</I> is specified
|
||||
with no <I>value</I>, then the command returns a list describing the
|
||||
one named option (this list will be identical to the corresponding
|
||||
sublist of the value returned if no <I>option</I> is specified). If
|
||||
one or more <I>option-value</I> pairs are specified, then the command
|
||||
modifies the given widget option(s) to have the given value(s); in
|
||||
this case the command returns an empty string.
|
||||
<I>Option</I> may have any of the values accepted by the <B>timefield</B>
|
||||
command.
|
||||
</DL>
|
||||
<DL>
|
||||
<DT> <I>pathName <B>get</B> ?<B>format</B>?
|
||||
</I></B>
|
||||
<DD> Returns the current contents of the timefield in a format of
|
||||
string or as an integer clock value using the <B>-string</B> and <B>-clicks</B>
|
||||
format options respectively. The default is by string. Reference the
|
||||
clock command for more information on obtaining times and their
|
||||
formats.
|
||||
</DL>
|
||||
<DL>
|
||||
<DT> <I>pathName <B>isvalid</B>
|
||||
</I></B>
|
||||
<DD> Returns a boolean indication of the validity of the currently
|
||||
displayed time value. For example, 12:59:59 is valid whereas
|
||||
25:59:59 is invalid.
|
||||
</DL>
|
||||
<DL>
|
||||
<DT> <I>pathName <B>show</B> <I>time</I>
|
||||
</I></B>
|
||||
<DD> Changes the currently displayed time to be that of the time
|
||||
argument. The time may be specified either as a string, an
|
||||
integer clock value or the keyword "now" (the default).
|
||||
Reference the clock command for more information on obtaining
|
||||
times and their formats.
