---++ Usage:
<pre>      GOSUB    --- .WIDGET SHOW SCROL BTN
      *        Check for errors
      IF       --- .WIDGET SHOW SCROL BTN      NE


</pre>
---++ Description:

This subroutine shows the previously hidden scroll buttons on the toolbar. There are no parameters.

This is only useful if you have hidden the scroll buttons via [[0LASubrWidgetHideScrolBtn][.WIDGET HIDE SCROL BTN]].

Note that this does not add the underlying --- WIDGET record, it just sets the --- WIDGET INVIS flag. You can delete them completely with [[0LASubrWidgetDelScrollBtn][.WIDGET DEL SCROLL BTN]]. If you have deleted them, this routine cannot show them.

Also note that normally scroll buttons are not shown on the toolbar. Before you can manipulate them with this routine, you would have to:

   * Modify the STANDARD TOOLBARS process in 0LC, changing the 'Show on Toolbar' GUI attribute of the appropriate Optional Children on the appropriate images. Save the new process in your application.
   * Hook the --- STANDARD TOOLBARS process with your new process. You can then manipulate the scroll buttons with this subroutine.
