<dl>
<dt> <h3>Name</h3><dd>
<p>Pmw.ComboBox() -  dropdown or simple combination box widget
</p>


<dt> <h3>Inherits</h3><dd>
<a href="MegaWidget.html">Pmw.MegaWidget</a><br>
<dt> <h3>Description</h3><dd>
<p>
    This class creates 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 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>

<p></p>


<dt> <h3>Options</h3><dd>
Options for this megawidget and its base
classes are described below.<p>
<a name=option.arrowrelief></a>
<dl><dt> <strong>arrowrelief

    dropdown combobox when it is in a normal state.  Acceptable values
    are <strong>'raised'</strong>, <strong>'sunken'</strong>, <strong>'flat'</strong>, <strong>'ridge'</strong>, and <strong>'groove'</strong>. 
    However, do not use <strong>'sunken'</strong> as this is the relief used to
    indicate a depressed state.  This option has no effect on simple
    comboboxes. The default is <strong>'raised'</strong>.</p>


</dt></dl>
<a name=option.autoclear></a>

        <strong>None</strong>, it should be a concatenation of one or two of the
        letters <strong>'n'</strong>, <strong>'s'</strong>, <strong>'e'</strong> and <strong>'w'</strong>.  The first letter
        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>,
        the label is placed in the centre of the left hand side; if
        it is <strong>'wn'</strong>, the label is placed at the top of the left
        hand side; if it is <strong>'ws'</strong>, the label is placed at the
        bottom of the left hand side.</p>
