_________________________________________________________________
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.
- -class
- -compound -cursor-image
- -state
- -style -takefocus-text
- -textvariable
- -underline -width
See the options 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,
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.)
