 | |
| <P>
 | |
| The <B>feedback</B> command creates a widget to display feedback on
 | |
| the current status of an ongoing operation to the user. Display is given as
 | |
| a percentage and as a thermometer type bar. Options exist for adding a label
 | |
| and controlling its position.
 | |
| 
 | |
| </pre><H2>METHODS</H2>
 | |
| <P>
 | |
| The <B>feedback</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 scrolledtext 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>scrolledhtml</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>feedback</B>
 | |
| command.
 | |
| </DL>
 | |
| <DL>
 | |
| <DT> <I>pathName</I> <B>reset</B>
 | |
| </I></B>
 | |
| <DD> Reset the current number of steps completed to 0, and configures the
 | |
| percentage complete label text to 0%
 | |
| </DL>
 | |
| <DL>
 | |
| <DT> <I>pathName</I> <B>step</B> ?<I>inc</I>?
 | |
| </I></B>
 | |
| <DD> Increase the current number of steps completed by the amount specified
 | |
| by <I>inc</I>. <I>Inc</I> defaults to 1.
 | |
| 
 | |
| </DL>
