DESCRIPTION
The iwidgets::checkbox command creates a check button box widget capable of adding, inserting, deleting,
selecting, and configuring checkbuttons as well as obtaining the currently selected button.
METHODS
The iwidgets::checkbox 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 checkbox take as one argument an indicator of which checkbutton of
the checkbox to operate on. These indicators are called indexes and allow reference and manipulation of
checkbuttons. Checkbox indexes may be specified in any of the following forms:
number Specifies the checkbutton numerically, where 0 corresponds to the top checkbutton of the
checkbox.
end Indicates the last checkbutton of the checkbox.
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 checkbutton in the checkbox, 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 checkbutton to the checkbuttond window on the bottom. The command takes additional
options which are passed on to the checkbutton as construction arguments. These include the
standard Tk checkbutton 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 checkbutton, whereas configureapplies to the options for the checkbox 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::checkbox 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::checkbox command.
pathName delete index
Deletes a specified checkbutton given an index.
pathName deselect index
Deselects a specified checkbutton given an index.
pathName flash index
Flashes a specified checkbutton given an index.
pathName get ?index?
Returns the tags of the currently selected checkbuttons or the selection status of specific
checkbutton when given an index.
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 checkbutton just before the one given by
index, instead of appending to the end of the checkbox. The option, and value arguments have the
same interpretation as for the add widget command.
pathName select index
Selects a specified checkbutton given an index.
