______________________________________________________________________________DESCRIPTION
The iwidgets::checkbox command creates a check button box widget capa‐
ble of adding, inserting, deleting, selecting, and configuring check‐
buttons 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 follow‐
ing 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 stan‐
dard 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 iwid‐
gets::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 avail‐
able 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 checkbut‐
ton 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.
