DESCRIPTION¶
ttk::radiobutton widgets are used in groups to show or change a set of
mutually-exclusive options. Radiobuttons are linked to a Tcl variable, and
have an associated value; when a radiobutton is clicked, it sets the variable
to its associated value.
STANDARD OPTIONS¶
-class -compound -cursor
-image -state -style
-takefocus -text -textvariable
-underline -width
See the
ttk_widget manual entry for details on the standard options.
Command-Line Name: -command
Database Name: command
Database Class: Command
- A Tcl script to evaluate whenever the widget is
invoked.
Command-Line Name: -value
Database Name: Value
Database Class: Value
- The value to store in the associated -variable when
the widget is selected.
Command-Line Name: -variable
Database Name: variable
Database Class: Variable
- The name of a global variable whose value is linked to the
widget. Default value is ::selectedButton.
In addition to the standard
cget,
configure,
identify,
instate, and
state commands, radiobuttons support the following
additional widget commands:
- pathname invoke
- Sets the -variable to the -value, selects the
widget, and evaluates the associated -command. Returns the result
of the -command, or the empty string if no -command is
specified.
The widget does not respond to user input if the
disabled state is set.
The widget sets the
selected state whenever the linked
-variable
is set to the widget's
-value, and clears it otherwise. The widget sets
the
alternate state whenever the linked
-variable is unset. (The
alternate state may be used to indicate a “tri-state” or
“indeterminate” selection.)
STANDARD STYLES¶
Ttk::radiobutton widgets support the
Toolbutton style in all
standard themes, which is useful for creating widgets for toolbars.
