WIDGET-SPECIFIC OPTIONS
Name: command
Class: Command
Command-Line Switch: -command
Specifies a Tcl command procedure to
be evaluated following a change in the current radio box
selection.
DESCRIPTION
The radiobox command creates a radio button box widget
capable of adding, inserting, deleting, selecting, and configuring
radiobuttons as well as obtaining the currently selected
button.
METHODS
The radiobox command creates a new Tcl command whose name
is pathName. This command may be used to invoke various
operations on the widget. It has the following general form:
pathName option ?arg arg ...?
Option and the args determine the exact behavior of
the command.
Many of the widget commands for the radiobox take as one
argument an indicator of which radiobutton of the radiobox to
operate on. These indicators are called indexes and allow
reference and manipulation of radiobuttons. Radiobox indexes may be
specified in any of the following forms:
- number
- Specifies the radiobutton numerically, where 0 corresponds to
the top radiobutton of the radiobox.
- end
- Indicates the last radiobutton of the radiobox.
- pattern
- If the index doesn't satisfy one of the above forms then this
form is used. Pattern is pattern-matched against the tag of
each radiobutton in the radiobox, in order from top to bottom,
until a matching entry is found. The rules of
Tcl_StringMatch are used.
WIDGET-SPECIFIC METHODS
- pathName add tag ?option value option
value?
- Adds a new radiobutton to the radiobuttond window on the
bottom. The command takes additional options which are passed on to
the radiobutton as construction arguments. These include the
standard Tk radiobutton options. The tag is returned.
- pathName buttonconfigure index
?options?
- This command is similar to the configure command, except
that it applies to the options for an individual radiobutton,
whereas configureapplies to the options for the radiobox as
a whole. Options may have any of the values accepted by the
add widget command. If options are specified, options
are modified as indicated in the command and the command returns an
empty string. If no options are specified, returns a list
describing the current options for entry index (see
Tk_ConfigureInfo for information on the format of this
list).
- pathName cget option
- Returns the current value of the configuration option given by
option. Option may have any of the values accepted by
the radiobox command.
- pathName configure ?option? ?value
option value ...?
- Query or modify the configuration options of the widget. If no
option is specified, returns a list describing all of the
available options for pathName (see Tk_ConfigureInfo
for information on the format of this list). If option is
specified with no value, then the command returns a list
describing the one named option (this list will be identical to the
corresponding sublist of the value returned if no option is
specified). If one or more option-value pairs are specified,
then the command modifies the given widget option(s) to have the
given value(s); in this case the command returns an empty string.
Option may have any of the values accepted by the
radiobox command.
- pathName delete index
- Deletes a specified radiobutton given an index.
- pathName deselect index
- Deselects a specified radiobutton given an index.
- pathName flash index
- Flashes a specified radiobutton given an index.
- pathName get
- Returns the tag of the currently selected radiobutton.
- pathName index index
- Returns the numerical index corresponding to index.
- pathName insert index tag ?option value
option value ...?
- Same as the add command except that it inserts the new
radiobutton just before the one given by index, instead of
appending to the end of the radiobox. The option, and
value arguments have the same interpretation as for the
add widget command.
- pathName select index
- Selects a specified radiobutton given an index.
