| </pre><H2>DESCRIPTION</H2> |
| <P> |
| |
| The <B>watch</B> command creates a watch with hour, minute, and |
| second hands modifying the time value. |
| |
| </pre><H2>METHODS</H2> |
| <P> |
| The <B>watch</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 watch 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>watch</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>watch</B> |
| command. |
| </DL> |
| <DL> |
| <DT> <I>pathName <B>get</B> ?<B>format</B>? |
| </I></B> |
| <DD> Returns the current time of the watch 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 time and its |
| formats. |
| </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". Reference the clock |
| command for more information on obtaining time and its format. |
| </DL> |
| <DL> |
| <DT> <I>pathName <B>watch</B> ?<B>args</B>? |
| </I></B> |
| <DD> Evaluates the specifieds <B>args</B> against the canvas component. |
