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.
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.
- 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.
