DESCRIPTION
The buttonbox command creates a manager widget for
controlling buttons. The button box also supports the display and
invocation of a default button. The button box can be configured
either horizontally or vertically.
METHODS
The buttonbox 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 buttonbox take as one
argument an indicator of which button of the button box to operate
on. These indicators are called indexes and allow reference
and manipulation of buttons regardless of their current map state.
buttonbox indexes may be specified in any of the following
forms:
- number
- Specifies the button numerically, where 0 corresponds to the
left/top-most button of the button box.
- end
- Indicates the right/bottom-most button of the button box.
- default
- Indicates the current default button of the button box. This is
the button with the default ring displayed.
- 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 button in the button box, in order from left/top to
right/left, until a matching entry is found. The rules of
Tcl_StringMatch are used.
WIDGET-SPECIFIC METHODS
- pathName add tag args
- Add a button distinguished by tag to the end of the
button box. If additional arguments are present they specify
options to be applied to the button. See PushButton for
information on the options available.
- pathName buttonconfigure index
?options?
- This command is similar to the configure command, except
that it applies to the options for an individual button, whereas
configure applies to the options for the button box as a
whole. Options may have any of the values accepted by the
PushButton 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 buttonbox 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
buttonbox command.
- pathName default index
- Sets the default button to the button given by index.
This causes the default ring to appear arround the specified
button.
- pathName delete index
- Deletes the button given by index from the button
box.
- pathName hide index
- Hides the button denoted by index. This doesn't remove
the button permanently, just inhibits its display.
- 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
button just before the one given by index, instead of
appending to the end of the button box. The option, and
value arguments have the same interpretation as for the
add widget command.
- pathName invoke ?index?
- Invoke the command associated with a button. If no arguments
are given then the current default button is invoked, otherwise the
argument is expected to be a button index.
- pathName show index
- Display a previously hidden button denoted by
index.
