Description

The iwidgets::buttonbox command creates a manager widget for con-

trolling 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 iwidgets::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 argu-

ment 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 config- ure 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 indi- cated 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::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 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::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 but-

ton 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.

Example

package require Iwidgets 4.0
iwidgets::buttonbox .bb

.bb add Yes -text Yes -command «puts Yes"
.bb add No -text No -command «puts No"
.bb add Maybe -text Maybe -command «puts Maybe" .bb default Yes

pack .bb -expand yes -fill both
