DESCRIPTION¶
The
iwidgets::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
iwidgets::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.
- 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
iwidgets::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 iwidgets::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.
