NAME

ttk::button - Widget that issues a command when pressed

SYNOPSIS

ttk::button pathName ?options?

DESCRIPTION

A button widget displays a textual label and/or image, and evaluates a command when pressed. -class -compound       -cursor -image
-state  -style  -takefocus      -text   
-textvariable   -underline      -width

OPTIONS

[ -command command Command ] A script to evaluate when the widget is invoked. [ -default default Default ] May be set to one of normal, active, or disabled. In a dialog box, one button may be designated the "default" button (meaning, roughly, "the one that gets invoked when the user presses <Enter>"). active indicates that this is currently the default button; normal means that it may become the default button, and disabled means that it is not defaultable. The default is normal.
Depending on the theme, the default button may be displayed with an extra highlight ring, or with a different border color. See also: keynav(n). [ -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 -width in the style.

WIDGET COMMAND

pathName invoke

Invokes the command associated with the button.

pathName cget option

pathName configure ?option? ?value option value ...?

pathName instate statespec ?script?

pathName state ?stateSpec?

See widget(n)

COMPATIBILITY OPTIONS

[ -state state State ] May be set to normal or disabled to control the disabled state bit. This is a ``write-only'' option: setting it changes the widget state, but the state widget command does not affect the state option.
