<dt> <h3>Description</h3></dt><dd>
<p>
    A combobox contains an entry field and an associated scrolled
    listbox.  When an item in the listbox is selected, it is displayed
    in the entry field.  Optionally, the user may also edit the entry
    field directly.</p>

<p>    For a simple combobox, the scrolled listbox is displayed beneath
    the entry field.  For a dropdown combobox (the default), the
    scrolled listbox is displayed in a window which pops up beneath
    the entry field when the user clicks on an arrow button on the
    right of the entry field.  Either style allows an optional label.</p>

    true. The default is <strong>1</strong>.</p>


</dd></dl>
<a name=option.labelmargin></a>
<dl><dt> <strong>labelmargin
</strong></dt><dd>

        specifies on which side of the megawidget to place the label. 
        If a second letter is specified, it indicates where on that
        side to place the label.  For example, if <strong>labelpos</strong> is <strong>'w'</strong>,

        it is <strong>'wn'</strong>, the label is placed at the top of the left

    If this function takes a long time to run, and you want the entry
    field to be updated quickly, call <code>update_idletasks()</code> at the
    beginning of the function.  Alternatively, wrap the function using
    <code>Pmw.busycallback()</code>. The default is <strong>None</strong>.</p>


</dd></dl>
<a name=option.sticky></a>
<dl><dt> <strong>sticky
</strong></dt><dd>

Initialisation option. If both <strong>unique</strong> and <strong>history</strong> are true, the current value of the
    entry field is not added to the listbox if it is already in the
    list. The default is <strong>1</strong>.</p>

<dt> <h3>Components</h3></dt><dd>
Components created by this megawidget and its base
classes are described below.<p></p>
<a name=component.arrowbutton></a>
<dl><dt> <strong>arrowbutton
</strong></dt><dd>
In a dropdown combobox, the button to popup the listbox. By default, this component is a Tkinter.Canvas.</p>


</dd></dl>
<a name=component.entryfield></a>
<dl><dt> <strong>entryfield
</strong></dt><dd>
The entry field where the current selection is displayed. By default, this component is a <a href="EntryField.html">Pmw.EntryField</a>.</p>

</dd></dl>
<a name=component.label></a>
<dl><dt> <strong>label
</strong></dt><dd>
If the <strong>labelpos</strong> option is not <strong>None</strong>, this component is
        created as a text label for the megawidget.  See the
        <strong>labelpos</strong> option for details.  Note that to set, for example,
        the <strong>text</strong> option of the label, you need to use the <strong>label_text</strong>
        component option. By default, this component is a Tkinter.Label.</p>


</dd></dl>

<dt> <h3>Component aliases</h3></dt><dd>
Sub-components of components of this megawidget
may be accessed via the following aliases.<p></p>
<dl><dt> <strong>entry

<dl><dt> <strong>listbox

Alias for <strong>scrolledlist_listbox</strong>.

<a name=methods></a>
<dt> <h3>Methods</h3></dt><dd>
Only methods specific to this megawidget are described below.
For a description of its inherited methods, see the
manual for its base class
<strong><a href="MegaWidget.html#methods">Pmw.MegaWidget</a></strong>.
In addition, methods from the following classes
are forwarded by this megawidget.
Methods from <strong><a href="ScrolledListBox.html#methods">Pmw.ScrolledListBox</a></strong>
are forwarded to the
<strong>scrolledlist</strong> component.
Methods from <strong><a href="EntryField.html#methods">Pmw.EntryField</a></strong>
are forwarded to the
<strong>entryfield</strong> component.
Forwarded methods are searched in the order given.
<p></p>
<a name=method.bbox></a>
<dl><dt> <strong>bbox</strong>(<em>index</em>)</dt><dd>
This method is explicitly forwarded to the <strong>scrolledlist</strong>
    component's <code>bbox()</code> method.  Without this explicit forwarding,
    the <code>bbox()</code> method (aliased to <code>grid_bbox()</code>) of the <strong>hull</strong> would
    be invoked, which is probably not what the programmer intended.</p>


</dd></dl>
<a name=method.clear></a>
<dl><dt> <strong>clear</strong>()</dt><dd>
Delete all items from the scrolled listbox and delete all text
    from the entry widget.</p>


</dd></dl>
<a name=method.get></a>
<dl><dt> <strong>get</strong>(<em>first</em> = <strong>None</strong>, <em>last</em> = <strong>None</strong>)</dt><dd>
This is the same as the <code>get()</code> method of the <strong>scrolledlist</strong>
    component, except that if <em>first</em> is <strong>None</strong> then
    the value of the entry field is returned.</p>


</dd></dl>
<a name=method.invoke></a>
<dl><dt> <strong>invoke</strong>()</dt><dd>
If a dropdown combobox, display the dropdown listbox.  In a simple
    combobox, select the currently selected item in the listbox,
    call the <strong>selectioncommand</strong> and return the result.</p>


</dd></dl>
<a name=method.selectitem></a>
<dl><dt> <strong>selectitem</strong>(<em>index</em>, <em>setentry</em> = <strong>1</strong>)</dt><dd>
Select the item in the listbox specified by <em>index</em> which may be
    either one of the items in the listbox or the integer index of one
    of the items in the listbox.</p>
<p>    If <em>setentry</em> is true, also set the entry field to the selected
    item.</p>


</dd></dl>
<a name=method.size></a>
<dl><dt> <strong>size</strong>()</dt><dd>
This method is explicitly forwarded to the <strong>scrolledlist</strong>
    component's <code>size()</code> method.  Without this explicit forwarding,
    the <code>size()</code> method (aliased to <code>grid_size()</code>) of the <strong>hull</strong> would
    be invoked, which is probably not what the programmer intended.</p>

232	This method is explicitly forwarded to the <strong>scrolledlist</strong>
233	component's <code>bbox()</code> method. Without this explicit forwarding,
234	the <code>bbox()</code> method (aliased to <code>grid_bbox()</code>) of the <strong>hull</strong> would
235	be invoked, which is probably not what the programmer intended.</p>

246	<a name=method.get></a>
247	<dl><dt> <strong>get</strong>(<em>first</em> = <strong>None</strong>, <em>last</em> = <strong>None</strong>)</dt><dd>
248	This is the same as the <code>get()</code> method of the <strong>scrolledlist</strong>
249	component, except that if <em>first</em> is <strong>None</strong> then
250	the value of the entry field is returned.</p>

256	If a dropdown combobox, display the dropdown listbox. In a simple

264	Select the item in the listbox specified by <em>index</em> which may be
265	either one of the items in the listbox or the integer index of one
266	of the items in the listbox.</p>
267	<p> If <em>setentry</em> is true, also set the entry field to the selected

273	<a name=method.size></a>

275	This method is explicitly forwarded to the <strong>scrolledlist</strong>
276	component's <code>size()</code> method. Without this explicit forwarding,
277	the <code>size()</code> method (aliased to <code>grid_size()</code>) of the <strong>hull</strong> would
