ttk::progressbar - Provide progress feedback

       A  ttk::progressbar  widget shows the status of a long-running operation.  They can operate in two modes:
       determinate mode shows the amount completed relative to  the  total  amount  of  work  to  be  done,  and
       indeterminate mode provides an animated display to let the user know that something is happening.

       If  the value of -orient is horizontal a text string can be displayed inside the progressbar. This string
       can be configured using the -anchor, -font, -foreground, -justify, -text and -wraplength options. If  the
       value of -orient is vertical then these options are ignored.

       The class name for a ttk::progressbar is TProgressbar.

       TProgressbar styling options configurable with ttk::style are:

       -backgroundcolor-bordercolorcolor-darkcolorcolor-lightcolorcolor-maxphase
              For the aqua theme.
       -period
              For the aqua theme.
       -troughcolorcolor

       Some options are only available for specific themes.

       See the ttk::style manual page for information on how to configure ttk styles.

________________________________________________________________________________________________________________

       In addition to the standard cget, configure, identifyelement, instate, state  and  style  commands  (see
       ttk::widget), progressbar widgets support the following additional commands:

       pathNamestart ?interval?
              Begin  autoincrement  mode:  schedules  a  recurring  timer  event  that calls step every interval
              milliseconds.  If omitted, interval defaults to 50 milliseconds (20 steps/second).

       pathNamestep ?amount?
              Increments the -value by amount.  amount defaults to 1.0 if omitted.

       pathNamestop
              Stop autoincrement mode: cancels any recurring timer event initiated by pathNamestart.

       Command-Line Name:-length
       Database Name:  length
       Database Class: Length

              Specifies  the  length  of  the  long  axis  of  the  progress bar (width if horizontal, height if
              vertical). The value may have any of the forms acceptable to Tk_GetPixels.

       Command-Line Name:-maximum
       Database Name:  maximum
       Database Class: Maximum

              A floating point number specifying the maximum -value.  Defaults to 100.

       Command-Line Name:-mode
       Database Name:  mode
       Database Class: Mode

              One of determinate or indeterminate.

       Command-Line Name:-orient
       Database Name:  orient
       Database Class: Orient

              One of horizontal or vertical.  Specifies the orientation of the progress bar.

       Command-Line Name:-phase
       Database Name:  phase
       Database Class: Phase

              Read-only option.  The widget periodically increments the value of this option whenever the -value
              is greater than 0 and, in determinate mode, less than -maximum.  This option may be  used  by  the
              current theme to provide additional animation effects.

       Command-Line Name:-value
       Database Name:  value
       Database Class: Value

              The  current  value  of the progress bar.  In determinate mode, this represents the amount of work
              completed.  In indeterminate mode, it is interpreted modulo -maximum; that is,  the  progress  bar
              completes  one  “cycle” when the -value increases by -maximum.  If -variable is set to an existing
              variable, specifying -value has no effect (the variable value takes precedence).

       Command-Line Name:-variable
       Database Name:  variable
       Database Class: Variable

              The name of a global Tcl variable which is linked to the -value.   If  specified  to  an  existing
              variable,  the  -value  of  the  progress  bar  is  automatically set to the value of the variable
              whenever the latter is modified.
