## Creating &kommander; Widgets

With Kommander you can create new widgets based on non-&kommander; widgets fairly easily. The approach is to derive your new &kommander; widget class from the &Qt;/&kde; widget which you wish to integrate with &kommander;, and then also from the KommanderWidget class. Overriding methods from this class gives the &kommander; widget its functionality.

Most of the code of a &kommander; widget is just template code. Therefore, you can use the widgetgenerator.kmdr &kommander; dialog to generate most the &kommander; widget code for you. All you have to do is fill in the important parts relating to your widget like any state information, widget text etc.
