<H2>DESCRIPTION</H2><PRE>
|
| 75 |
|
|
The <STRONG>buttonbox</STRONG> command creates a manager widget for control-
|
| 76 |
|
|
ling buttons. The button box also supports the display and
|
| 77 |
|
|
invocation of a default button. The button box can be con-
|
| 78 |
|
|
figured either horizontally or vertically.

|
<H2>METHODS</H2><PRE>
|
| 84 |
|
|
The <STRONG>buttonbox</STRONG> command creates a new Tcl command whose name
|
| 85 |
|
|
is <EM>pathName</EM>. This command may be used to invoke various
|
| 86 |
|
|
operations on the widget. It has the following general
|
| 87 |
|
|
form:
|
| 88 |
|
|
|
| 89 |
|
|
<EM>pathName</EM> <EM>option</EM> ?<EM>arg</EM> <EM>arg</EM> ...?
|
| 90 |
|
|
|
| 91 |
|
|
<EM>Option</EM> and the <EM>arg</EM>s determine the exact behavior of the com-
|
| 92 |
|
|
mand.
|
| 93 |
|
|
|
| 94 |
|
|
Many of the widget commands for the buttonbox take as one
|
| 95 |
|
|
argument an indicator of which button of the button box to
|
| 96 |
|
|
operate on. These indicators are called <EM>indexes</EM> and allow
|
| 97 |
|
|
reference and manipulation of buttons regardless of their
|
| 98 |
|
|
current map state. buttonbox indexes may be specified in
|
| 99 |
|
|
any of the following forms:
|
| 100 |
|
|
|
| 101 |
|
|
<EM>number</EM> Specifies the button numerically, where 0
|
| 102 |
|
|
corresponds to the left/top-most button of the
|
| 103 |
|
|
button box.
|
| 104 |
|
|
|
| 105 |
|
|
<STRONG>end</STRONG> Indicates the right/bottom-most button of the
|
| 106 |
|
|
button box.
|
| 107 |
|
|
|
| 108 |
|
|
<STRONG>default</STRONG> Indicates the current default button of the but-
|
| 109 |
|
|
ton box. This is the button with the default
|
| 110 |
|
|
ring displayed.
|
| 111 |
|
|
|
| 112 |
|
|
<EM>pattern</EM> If the index doesn't satisfy one of the above
|
| 113 |
|
|
forms then this form is used. <EM>Pattern</EM> is
|
| 114 |
|
|
pattern-matched against the tag of each button
|
| 115 |
|
|
in the button box, in order from left/top to
|
| 116 |
|
|
right/left, until a matching entry is found.
|
| 117 |
|
|
The rules of <STRONG>Tcl_StringMatch</STRONG> are used.

<H2>WIDGET-SPECIFIC METHODS</H2><PRE>
|
| 123 |
|
|
<EM>pathName</EM> <STRONG>add</STRONG> <EM>tag</EM> <EM>args</EM>
|
| 124 |
|
|
Add a button distinguished by <EM>tag</EM> to the end of the
|
| 125 |
|
|
button box. If additional arguments are present they
|
| 126 |
|
|
specify options to be applied to the button. See <STRONG>Push-</STRONG>
|
| 127 |
|
|
<STRONG>Button</STRONG> for information on the options available.
|
| 128 |
|
|
|
| 129 |
|
|
<EM>pathName</EM> <STRONG>buttonconfigure</STRONG> <EM>index</EM> ?<EM>options</EM>?
|
| 130 |
|
|
This command is similar to the <STRONG>configure</STRONG> command,
|
| 131 |
|
|
except that it applies to the options for an individual
|
| 132 |
|
|
button, whereas <STRONG>configure</STRONG> applies to the options for
|
| 133 |
|
|
the button box as a whole. <EM>Options</EM> may have any of the
|
| 134 |
|
|
values accepted by the <STRONG>PushButton</STRONG> command. If <EM>options</EM>
|
| 135 |
|
|
are specified, options are modified as indicated in the
|
| 136 |
|
|
command and the command returns an empty string. If no
|
| 137 |
|
|
<EM>options</EM> are specified, returns a list describing the
|
| 138 |
|
|
current options for entry <EM>index</EM> (see <STRONG>Tk_ConfigureInfo</STRONG>
|
| 139 |
|
|
for information on the format of this list).
|
| 140 |
|
|
|
| 141 |
|
|
<EM>pathName</EM> <STRONG>cget</STRONG> <EM>option</EM>
|
| 142 |
|
|
Returns the current value of the configuration option
|
| 143 |
|
|
given by <EM>option</EM>. <EM>Option</EM> may have any of the values
|
| 144 |
|
|
accepted by the <STRONG>buttonbox</STRONG> command.
|
| 145 |
|
|
|
| 146 |
|
|
<EM>pathName</EM> <STRONG>configure</STRONG> ?<EM>option</EM>? ?<EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
|
| 147 |
|
|
Query or modify the configuration options of the
|
| 148 |
|
|
widget. If no <EM>option</EM> is specified, returns a list
|
| 149 |
|
|
describing all of the available options for <EM>pathName</EM>
|
| 150 |
|
|
(see <STRONG>Tk_ConfigureInfo</STRONG> for information on the format of
|
| 151 |
|
|
this list). If <EM>option</EM> is specified with no <EM>value</EM>, then
|
| 152 |
|
|
the command returns a list describing the one named
|
| 153 |
|
|
option (this list will be identical to the correspond-
|
| 154 |
|
|
ing sublist of the value returned if no <EM>option</EM> is
|
| 155 |
|
|
specified). If one or more <EM>option</EM> - <EM>value</EM> pairs are
|
| 156 |
|
|
specified, then the command modifies the given widget
|
| 157 |
|
|
option(s) to have the given value(s); in this case the
|
| 158 |
|
|
command returns an empty string. <EM>Option</EM> may have any
|
| 159 |
|
|
of the values accepted by the <STRONG>buttonbox</STRONG> command.
|
| 160 |
|
|
|
| 161 |
|
|
<EM>pathName</EM> <STRONG>default</STRONG> <EM>index</EM>
|
| 162 |
|
|
Sets the default button to the button given by <EM>index</EM>.
|
| 163 |
|
|
This causes the default ring to appear arround the
|
| 164 |
|
|
specified button.
|
| 165 |
|
|
|
| 166 |
|
|
<EM>pathName</EM> <STRONG>delete</STRONG> <EM>index</EM>
|
| 167 |
|
|
Deletes the button given by <EM>index</EM> from the button box.
|
| 168 |
|
|
|
| 169 |
|
|
<EM>pathName</EM> <STRONG>hide</STRONG> <EM>index</EM>
|
| 170 |
|
|
Hides the button denoted by <EM>index</EM>. This doesn't remove
|
| 171 |
|
|
the button permanently, just inhibits its display.
|
| 172 |
|
|
|
| 173 |
|
|
<EM>pathName</EM> <STRONG>index</STRONG> <EM>index</EM>
|
| 174 |
|
|
Returns the numerical index corresponding to <EM>index</EM>.
|
| 175 |
|
|
|
| 176 |
|
|
<EM>pathName</EM> <STRONG>insert</STRONG> <EM>index</EM> <EM>tag</EM> ?<EM>option</EM> <EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
|
| 177 |
|
|
Same as the <STRONG>add</STRONG> command except that it inserts the new
|
| 178 |
|
|
button just before the one given by <EM>index</EM>, instead of
|
| 179 |
|
|
appending to the end of the button box. The <EM>option</EM>,
|
| 180 |
|
|
and <EM>value</EM> arguments have the same interpretation as for
|
| 181 |
|
|
the <STRONG>add</STRONG> widget command.
|
| 182 |
|
|
|
| 183 |
|
|
<EM>pathName</EM> <STRONG>invoke</STRONG> ?<EM>index</EM>?
|
| 184 |
|
|
Invoke the command associated with a button. If no
|
| 185 |
|
|
arguments are given then the current default button is
|
| 186 |
|
|
invoked, otherwise the argument is expected to be a
|
| 187 |
|
|
button <EM>index</EM>.
|
| 188 |
|
|
|
| 189 |
|
|
<EM>pathName</EM> <STRONG>show</STRONG> <EM>index</EM>
|
| 190 |
|
|
Display a previously hidden button denoted by <EM>index</EM>.
