79Specifies a function to call whenever a button in the button box
80 is invoked or the window is deleted by the window manager. The
81 function is called with a single argument, which is the name of
82 the button which was invoked, or <strong>None</strong> if the window was deleted
83 by the window manager.</p>
84<p> If the value of <strong>command</strong> is not callable, the default behaviour
85 is to deactivate the window if it is active, or withdraw the
86 window if it is not active. If it is deactivated, <code>deactivate()</code>
87 is called with the button name or <strong>None</strong> as described above. The default is <strong>None</strong>.</p>

110<a name=option.master></a>
111<dl><dt> <strong>master

116
117
118</dd></dl>
119<a name=option.separatorwidth></a>
120<dl><dt> <strong>separatorwidth
121</strong></dt><dd>
122Initialisation option. If this is greater than <strong>0</strong>, a separator line with the specified
123 width will be created between the button box and the child site,
124 as a component named <strong>separator</strong>. Since the default border of the
125 button box and child site is <strong>raised</strong>, this option does not
126 usually need to be set for there to be a visual separation between
127 the button box and child site. The default is <strong>0</strong>.</p>

142classes are described below.<p></p>
143<a name=component.buttonbox></a>
144<dl><dt> <strong>buttonbox
145</strong></dt><dd>
146This is the button box containing the buttons for the dialog. By
147 default it is created with the options
148 <code>(hull_borderwidth = 1, hull_relief = 'raised')</code>. By default, this component is a <a href="ButtonBox.html">Pmw.ButtonBox</a>.</p>
149
150
151</dd></dl>
152<a name=component.combobox></a>
153<dl><dt> <strong>combobox
154</strong></dt><dd>
155The combobox for the user to enter a value. By default it is
156 created using the option <code>dropdown = 0</code>. By default, this component is a <a href="ComboBox.html">Pmw.ComboBox</a>.</p>
157
158
159</dd></dl>
160<a name=component.dialogchildsite></a>
161<dl><dt> <strong>dialogchildsite
162</strong></dt><dd>
163This is the child site for the dialog, which may be used to
164 specialise the megawidget by creating other widgets within it. By
165 default it is created with the options
166 <code>(borderwidth = 1, relief = 'raised')</code>. By default, this component is a Tkinter.Frame.</p>
167
168
169</dd></dl>
170<a name=component.hull></a>
171<dl><dt> <strong>hull
172</strong></dt><dd>
173This acts as the body for the entire megawidget. Other components
174 are created as children of the hull to further specialise this
175 class. By default, this component is a Tkinter.Toplevel.</p>
176
177
178</dd></dl>
179<a name=component.separator></a>
180<dl><dt> <strong>separator
181</strong></dt><dd>
182If the <strong>separatorwidth</strong> initialisation option is non-zero, the
183 <strong>separator</strong> component is the line dividing the area between the
184 button box and the child site. By default, this component is a Tkinter.Frame.</p>

210<dt> <h3>Methods</h3></dt><dd>
211Only methods specific to this megawidget are described below.
212For a description of its inherited methods, see the
213manual for its base class
214<strong><a href="Dialog.html#methods">Pmw.Dialog</a></strong>.
215In addition, methods from the
216<strong><a href="ComboBox.html#methods">Pmw.ComboBox</a></strong> class
217are forwarded by this megawidget to the
218<strong>combobox</strong> component.
219<p></p>
220<a name=method.bbox></a>
221<dl><dt> <strong>bbox</strong>(<em>index</em>)</dt><dd>
222This method is explicitly forwarded to the <strong>combobox</strong> component's
223 <code>bbox()</code> method. Without this explicit forwarding, the <code>bbox()</code>
224 method (aliased to <code>grid_bbox()</code>) of the <strong>hull</strong> would be invoked,
225 which is probably not what the programmer intended.</p>
226
227
228</dd></dl>
229<a name=method.size></a>
230<dl><dt> <strong>size</strong>()</dt><dd>
231This method is explicitly forwarded to the <strong>combobox</strong> component's
232 <code>size()</code> method. Without this explicit forwarding, the <code>size()</code>
233 method (aliased to <code>grid_size()</code>) of the <strong>hull</strong> would be invoked,
234 which is probably not what the programmer intended.</p>
