.TH ttk::progressbar n 8.5 Tk "Tk Themed Widget"
.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.SH NAME
ttk::progressbar \- Provide progress feedback
.SH SYNOPSIS
\fBttk::progressbar\fR \fIpathName \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.
.SO ttk_widget
\-class	\-cursor	\-takefocus
\-style
.SE
.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).
.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
.TP
\fIpathName \fBcget \fIoption\fR
Returns the current value of the specified \fIoption\fR; see \fIttk::widget(n)\fR.
.TP
\fIpathName \fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR?
Modify or query widget options; see \fIttk::widget(n)\fR.
.TP
\fIpathName \fBidentify \fIx y\fR
Returns the name of the element at position \fIx\fR, \fIy\fR.
See \fIttk::widget(n)\fR.
.TP
\fIpathName \fBinstate \fIstatespec\fR ?\fIscript\fR?
Test the widget state; see \fIttk::widget(n)\fR.
.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).
.TP
\fIpathName \fBstate\fR ?\fIstateSpec\fR?
Modify or query the widget state; see \fIttk::widget(n)\fR.
.TP
\fIpathName \fBstep\fR ?\fIamount\fR?
Increments the \fB\-value\fR by \fIamount\fR.
\fIamount\fR defaults to 1.0 if omitted.
.TP
\fIpathName \fBstop\fR
Stop autoincrement mode:
cancels any recurring timer event initiated by \fIpathName \fBstart\fR.
