.TH ttk::button 3tk 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::button \- Widget that issues a command when pressed
.SH SYNOPSIS
\fBttk::button\fR \fIpathName \fR?\fIoptions\fR?
.BE
.SH DESCRIPTION
A \fBttk::button\fR widget displays a textual label and/or image,
and evaluates a command when pressed.
.SO ttk_widget
\-class	\-compound	\-cursor
\-image	\-state	\-style
\-takefocus	\-text	\-textvariable
\-underline	\-width
.SE
.SH "WIDGET-SPECIFIC OPTIONS"
.OOP \-command command Command
A script to evaluate when the widget is invoked.
.OOP \-default default Default
May be set to one of  \fBnormal\fR, \fBactive\fR, or \fBdisabled\fR.
In a dialog box, one button may be designated the
.QW default
button (meaning, roughly,
.QW "the one that gets invoked when the user presses <Enter>" ).
\fBactive\fR indicates that this is currently the default button;
\fBnormal\fR means that it may become the default button, and
\fBdisabled\fR means that it is not defaultable.
The default is \fBnormal\fR.
.RS
.PP
Depending on the theme, the default button may be displayed 
with an extra highlight ring, or with a different border color.
.RE
.OOP \-width width Width
If greater than zero, specifies how much space, in character widths, 
to allocate for the text label.  
If less than zero, specifies a minimum width.
If zero or unspecified, the natural width of the text label is used.
Note that some themes may specify a non-zero \fB\-width\fR
in the style.
.\" Not documented -- may go away

.SH "WIDGET COMMAND"
.PP
In addition to the standard 
\fBcget\fR, \fBconfigure\fR, \fBidentify\fR, \fBinstate\fR, and \fBstate\fR 
commands, buttons support the following additional widget commands:
.TP
\fIpathName \fBinvoke\fR
Invokes the command associated with the button.
.SH "STANDARD STYLES"
.PP
\fBTtk::button\fR widgets support the \fBToolbutton\fR style in all standard
themes, which is useful for creating widgets for toolbars.
.SH "COMPATIBILITY OPTIONS"
.OOP \-state state State
May be set to \fBnormal\fR or \fBdisabled\fR to control the
\fBdisabled\fR state bit. This is a
.QW write-only
option: setting it changes the widget state, but the \fBstate\fR
widget command does not affect the state option.
