.SH NAME
ttk::progressbar \- Provide progress feedback
.SH SYNOPSIS
\fBttk::progressbar\fI pathName \fR?\fIoptions\fR?
.BE
.SH DESCRIPTION
.PP
A \fBttk::progressbar\fR widget shows the status of a long-running
operation.  They can operate in two modes: \fIdeterminate\fR mode shows the
amount completed relative to the total amount of work to be done, and
\fIindeterminate\fR mode provides an animated display to let the user know
that something is happening.
.PP
If the value of \fB\-orient\fR is \fBhorizontal\fR a text string can be
displayed inside the progressbar. This string can be configured using
the \fB\-anchor\fR, \fB\-font\fR, \fB\-foreground\fR, \fB\-justify\fR,
\fB\-text\fR and \fB\-wraplength\fR options. If the value of \fB\-orient\fR
is \fBvertical\fR then these options are ignored.

.SH "WIDGET-SPECIFIC OPTIONS"
.OP \-length length 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 \fBTk_GetPixels\fR.
.OP \-maximum maximum Maximum
A floating point number specifying the maximum \fB\-value\fR.
Defaults to 100.
.OP \-mode mode Mode
One of \fBdeterminate\fR or \fBindeterminate\fR.
.OP \-orient orient Orient
One of \fBhorizontal\fR or \fBvertical\fR.
Specifies the orientation of the progress bar.
.OP \-phase phase Phase
Read-only option.
The widget periodically increments the value of this option
whenever the \fB\-value\fR is greater than 0 and,
in \fIdeterminate\fR mode, less than \fB\-maximum\fR.
This option may be used by the current theme
to provide additional animation effects.
.OP \-value value Value
The current value of the progress bar.
In \fIdeterminate\fR mode, this represents the amount of work completed.
In \fIindeterminate\fR mode, it is interpreted modulo \fB\-maximum\fR;
that is, the progress bar completes one
.QW cycle
when the \fB\-value\fR increases by \fB\-maximum\fR.
If \fB\-variable\fR is set to an existing variable, specifying \fB\-value\fR
has no effect (the variable value takes precedence).
.OP \-variable variable Variable
The name of a global Tcl variable which is linked to the \fB\-value\fR.
If specified to an existing variable, the \fB\-value\fR of the progress bar is
automatically set to the value of the variable whenever
the latter is modified.
.SH "WIDGET COMMAND"
.PP
In addition to the standard
\fBcget\fR, \fBconfigure\fR, \fBidentify element\fR, \fBinstate\fR,
\fBstate\fR and \fBstyle\fR
commands (see \fBttk::widget\fR),
progressbar widgets support the following additional commands:
.\" METHOD: start
.TP
\fIpathName \fBstart\fR ?\fIinterval\fR?
.
Begin autoincrement mode:
schedules a recurring timer event that calls \fBstep\fR
every \fIinterval\fR milliseconds.
If omitted, \fIinterval\fR defaults to 50 milliseconds (20 steps/second).
.\" METHOD: step
.TP
\fIpathName \fBstep\fR ?\fIamount\fR?
.
Increments the \fB\-value\fR by \fIamount\fR.
\fIamount\fR defaults to 1.0 if omitted.
.\" METHOD: stop
.TP
\fIpathName \fBstop\fR
.
Stop autoincrement mode:
cancels any recurring timer event initiated by \fIpathName \fBstart\fR.
