EEF/User Guide/Custom Element Editor

Need of new widget ?

EEF generators offer a set of widget to build EMF editing forms. Sometime other widget needs appear to create more efficient GUIs. In this case, EEF users can employ CustomPropertiesEditionElement to generate user code areas inside the EEF properties code.

The first step is to replace the PropertiesEditionElement generated by the EEF Initializer with a CustomPropertiesEditionElement. This must be done in the PropertiesEditionComponent associated to our EClass Person, the Person PropertiesEditionElement.
