NAME

ttk::progressbar - Provide progress feedback

SYNOPSIS

ttk::progressbar pathName ?options?

---

DESCRIPTION

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
 -style
 
 

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

WIDGET-SPECIFIC OPTIONS

 
 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:-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:-mode
 Database Name:mode
 Database Class:Mode
 

One of determinate or indeterminate.

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

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

 
 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.

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

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

 
 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.
