<h1>KCompletionBox Class Reference</h1>
<code>from PyKDE4.kdeui import *</code>

Inherits: <a href="../kdeui/KListWidget.html">KListWidget</a> → QListWidget → QListView → QAbstractItemView → QAbstractScrollArea → QFrame → QWidget → QObject<br />
<h2>Detailed Description</h2>
<p>A helper widget for "completion-widgets" (KLineEdit, KComboBox))
</p>
<p>
A little utility class for "completion-widgets", like KLineEdit or
KComboBox. KCompletionBox is a listbox, displayed as a rectangle without
any window decoration, usually directly under the lineedit or combobox.
It is filled with all possible matches for a completion, so the user
can select the one he wants.
</p>
<p>
It is used when KGlobalSettings.Completion == CompletionPopup or CompletionPopupAuto.
