Provide progress feedback


ttk::progressbar pathName ?options?


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.

Standard Options

-class	-cursor	-takefocus

See the ttk_widget manual entry for details on the standard options.

Widget-Specific Options

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).

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.
