NAME¶
ttk::radiobutton - Mutually exclusive option widget
SYNOPSIS¶
ttk::radiobutton pathName ?options?
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.
