Section: Tk Themed Widget (n)
ttk::button - Widget that issues a command when pressed
widget displays a textual label and/or image,
and evaluates a command when pressed.
See the ttk_widget manual entry for details on the standard options.
A script to evaluate when the widget is invoked.
May be set to one of normal, active, or disabled.
In a dialog box, one button may be designated the
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.
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.
In addition to the standard
cget, configure, identify, instate, and state
commands, buttons support the following additional widget commands:
- pathName invoke
Invokes the command associated with the button.
Ttk::button widgets support the Toolbutton style in all standard
themes, which is useful for creating widgets for toolbars.
May be set to normal or disabled to control the
disabled state bit. This is a
option: setting it changes the widget state, but the state
widget command does not affect the state option.
