<H2>DESCRIPTION</H2><PRE>
|
| 64 |
|
|
The <STRONG>radiobox</STRONG> command creates a radio button box widget capa-
|
| 65 |
|
|
ble of adding, inserting, deleting, selecting, and configur-
|
| 66 |
|
|
ing radiobuttons as well as obtaining the currently selected
|
| 67 |
|
|
button.

<H2>METHODS</H2><PRE>
|
| 73 |
|
|
The <STRONG>radiobox</STRONG> command creates a new Tcl command whose name is
|
| 74 |
|
|
<EM>pathName</EM>. This command may be used to invoke various opera-
|
| 75 |
|
|
tions on the widget. It has the following general form:
|
| 76 |
|
|
|
| 77 |
|
|
<EM>pathName</EM> <EM>option</EM> ?<EM>arg</EM> <EM>arg</EM> ...?
|
| 78 |
|
|
|
| 79 |
|
|
<EM>Option</EM> and the <EM>arg</EM>s determine the exact behavior of the com-
|
| 80 |
|
|
mand.
|
| 81 |
|
|
Many of the widget commands for the <STRONG>radiobox</STRONG> take as one
|
| 82 |
|
|
argument an indicator of which radiobutton of the radiobox
|
| 83 |
|
|
to operate on. These indicators are called <EM>indexes</EM> and
|
| 84 |
|
|
allow reference and manipulation of radiobuttons. Radiobox
|
| 85 |
|
|
indexes may be specified in any of the following forms:
|
| 86 |
|
|
|
| 87 |
|
|
<EM>number</EM> Specifies the radiobutton numerically, where 0
|
| 88 |
|
|
corresponds to the top radiobutton of the
|
| 89 |
|
|
radiobox.
|
| 90 |
|
|
|
| 91 |
|
|
<STRONG>end</STRONG> Indicates the last radiobutton of the radiobox.
|
| 92 |
|
|
|
| 93 |
|
|
<EM>pattern</EM> If the index doesn't satisfy one of the above
|
| 94 |
|
|
forms then this form is used. <EM>Pattern</EM> is
|
| 95 |
|
|
pattern-matched against the tag of each
|
| 96 |
|
|
radiobutton in the radiobox, in order from top
|
| 97 |
|
|
to bottom, until a matching entry is found. The
|
| 98 |
|
|
rules of <STRONG>Tcl_StringMatch</STRONG> are used.

<H2>WIDGET-SPECIFIC METHODS</H2><PRE>
|
| 104 |
|
|
<EM>pathName</EM> <STRONG>add</STRONG> <EM>tag</EM> ?<EM>option</EM> <EM>value</EM> <EM>option</EM> <EM>value</EM>?
|
| 105 |
|
|
Adds a new radiobutton to the radiobuttond window on
|
| 106 |
|
|
the bottom. The command takes additional options which
|
| 107 |
|
|
are passed on to the radiobutton as construction argu-
|
| 108 |
|
|
ments. These include the standard Tk radiobutton
|
| 109 |
|
|
options. The tag is returned.
|
| 110 |
|
|
|
| 111 |
|
|
<EM>pathName</EM> <STRONG>buttonconfigure</STRONG> <EM>index</EM> ?<EM>options</EM>?
|
| 112 |
|
|
This command is similar to the <STRONG>configure</STRONG> command,
|
| 113 |
|
|
except that it applies to the options for an individual
|
| 114 |
|
|
radiobutton, whereas <STRONG>configure</STRONG>applies to the options
|
| 115 |
|
|
for the radiobox as a whole. <EM>Options</EM> may have any of
|
| 116 |
|
|
the values accepted by the <STRONG>add</STRONG> widget command. If
|
| 117 |
|
|
<EM>options</EM> are specified, options are modified as indi-
|
| 118 |
|
|
cated in the command and the command returns an empty
|
| 119 |
|
|
string. If no <EM>options</EM> are specified, returns a list
|
| 120 |
|
|
describing the current options for entry <EM>index</EM> (see
|
| 121 |
|
|
<STRONG>Tk_ConfigureInfo</STRONG> for information on the format of this
|
| 122 |
|
|
list).
|
| 123 |
|
|
|
| 124 |
|
|
<EM>pathName</EM> <STRONG>cget</STRONG> <EM>option</EM>
|
| 125 |
|
|
Returns the current value of the configuration option
|
| 126 |
|
|
given by <EM>option</EM>. <EM>Option</EM> may have any of the values
|
| 127 |
|
|
accepted by the <STRONG>radiobox</STRONG> command.
|
| 128 |
|
|
|
| 129 |
|
|
<EM>pathName</EM> <STRONG>configure</STRONG> ?<EM>option</EM>? ?<EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
|
| 130 |
|
|
Query or modify the configuration options of the
|
| 131 |
|
|
widget. If no <EM>option</EM> is specified, returns a list
|
| 132 |
|
|
describing all of the available options for <EM>pathName</EM>
|
| 133 |
|
|
(see <STRONG>Tk_ConfigureInfo</STRONG> for information on the format of
|
| 134 |
|
|
this list). If <EM>option</EM> is specified with no <EM>value</EM>, then
|
| 135 |
|
|
the command returns a list describing the one named
|
| 136 |
|
|
option (this list will be identical to the correspond-
|
| 137 |
|
|
ing sublist of the value returned if no <EM>option</EM> is
|
| 138 |
|
|
specified). If one or more <EM>option</EM> - <EM>value</EM> pairs are
|
| 139 |
|
|
specified, then the command modifies the given widget
|
| 140 |
|
|
option(s) to have the given value(s); in this case the
|
| 141 |
|
|
command returns an empty string. <EM>Option</EM> may have any
|
| 142 |
|
|
of the values accepted by the <STRONG>radiobox</STRONG> command.
|
| 143 |
|
|
|
| 144 |
|
|
<EM>pathName</EM> <STRONG>delete</STRONG> <EM>index</EM>
|
| 145 |
|
|
Deletes a specified radiobutton given an <EM>index</EM>.
|
| 146 |
|
|
|
| 147 |
|
|
<EM>pathName</EM> <STRONG>deselect</STRONG> <EM>index</EM>
|
| 148 |
|
|
Deselects a specified radiobutton given an <EM>index</EM>.
|
| 149 |
|
|
|
| 150 |
|
|
<EM>pathName</EM> <STRONG>flash</STRONG> <EM>index</EM>
|
| 151 |
|
|
Flashes a specified radiobutton given an <EM>index</EM>.
|
| 152 |
|
|
|
| 153 |
|
|
<EM>pathName</EM> <STRONG>get</STRONG>
|
| 154 |
|
|
Returns the tag of the currently selected radiobutton.
|
| 155 |
|
|
|
| 156 |
|
|
<EM>pathName</EM> <STRONG>index</STRONG> <EM>index</EM>
|
| 157 |
|
|
Returns the numerical index corresponding to index.
|
| 158 |
|
|
|
| 159 |
|
|
<EM>pathName</EM> <STRONG>insert</STRONG> <EM>index</EM> <EM>tag</EM> ?<EM>option</EM> <EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
|
| 160 |
|
|
Same as the <STRONG>add</STRONG> command except that it inserts the new
|
| 161 |
|
|
radiobutton just before the one given by <EM>index</EM>, instead
|
| 162 |
|
|
of appending to the end of the radiobox. The <EM>option</EM>,
|
| 163 |
|
|
and <EM>value</EM> arguments have the same interpretation as for
|
| 164 |
|
|
the <STRONG>add</STRONG> widget command.
|
| 165 |
|
|
|
| 166 |
|
|
<EM>pathName</EM> <STRONG>select</STRONG> <EM>index</EM>
|
| 167 |
|
|
Selects a specified radiobutton given an <EM>index</EM>.
