<div class="textblock"><p>A widget that provides a drop-down combo-box control. </p>
<p>A combo box provides the user with a set of options, from which one option may be selected.</p>
<p>WComboBox is an MVC view class, using a simple string list model by default. The model may be populated using <a class="el" href="classWt_1_1WComboBox.html#a9b2308a7d962ceb17c1ee32627b106d4" title="Adds an option item.">addItem(const WString&amp;)</a> or <a class="el" href="classWt_1_1WComboBox.html#a2092c15c7c0c2f77342d0abdc393ca6b" title="Inserts an item at the specified position.">insertItem(int, const WString&amp;)</a> and the contents can be cleared through <a class="el" href="classWt_1_1WComboBox.html#a0ed207e9616b51089d97030cc767409d" title="Clears all items.">clear()</a>. These methods manipulate the underlying <a class="el" href="classWt_1_1WComboBox.html#a20b54b2271b0219c2375775538d454a3" title="Returns the data model.">model()</a>.</p>
<p>To use the combo box with a custom model instead of the default <a class="el" href="classWt_1_1WStringListModel.html" title="An model that manages a list of strings.">WStringListModel</a>, use <a class="el" href="classWt_1_1WComboBox.html#a3d10438b053fe43dcd05e66b7ca78826" title="Sets the model to be used for the items.">setModel()</a>.</p>
<p>To react to selection events, connect to the <a class="el" href="classWt_1_1WFormWidget.html#a5216ba1594b5dc525cc47cad593c7ba8" title="Signal emitted when the value was changed.">changed()</a>, <a class="el" href="classWt_1_1WComboBox.html#ac39b46ccd8134a5397b4cbd87dc9f01f" title="Signal emitted when the selection changed.">activated()</a> or <a class="el" href="classWt_1_1WComboBox.html#a06401499734540c65db26fceb60bfdbf" title="Signal emitted when the selection changed.">sactivated()</a> signals.</p>
<p>At all times, the current selection index is available through <a class="el" href="classWt_1_1WComboBox.html#a94b6a87121adab0abbf23562d35a716e" title="Returns the currently selected item.">currentIndex()</a> and the current selection text using <a class="el" href="classWt_1_1WComboBox.html#aec0856e1bacf24fded9621054a0c357c" title="Returns the text of the currently selected item.">currentText()</a>.</p>
<p><a class="el" href="classWt_1_1WComboBox.html" title="A widget that provides a drop-down combo-box control.">WComboBox</a> does not have support for auto-completion, this behaviour can be found in the <a class="el" href="classWt_1_1WSuggestionPopup.html" title="A widget which popups to assist in editing a textarea or lineedit.">WSuggestionPopup</a>.</p>
