Mastering SAP ABAP

Custom controls

Even though the SAPUI5 library is vast and contains various controls, sometimes it is impossible to find the control that really fits the requirements. In this case, the developer can leverage the inheritance model and the elasticity introduced in the library. Depending on the actual needs, you can gather the few existing controls into a new one implementing some additional logic and automation, or extend one of the classes (for example sap.ui.core.Control) manually, providing appropriate control interface properties, rendering methods, events, and so on. Once the new control is instantiated, the core processor will take care of its life cycle and event processing the same way that it does with the standard ones.
