2.8 Examples and Discussion

The goal of DSPLs is to be able to handle both static and dynamic variability. Our work attempts to bridge the gap closer to also handling the GUI also. In this section, we aim to highlight some examples using the approach described earlier, and discuss some of the current limitations of the approach, with future and ongoing work described last.

2.8.1 Examples

Having described our approach earlier in this chapter, we now attempt to show its applicability using examples from the SPL introduced at the beginning. In Sect. 2.2.2, we introduced nine categories of GUI variability. These categories are based on different aspects of the GUI. Many of these categories however are often implemented in the same way. As an example, if we consider the categories properties of UI elements and visual appearance, they are both implemented on Android by either adding or refining different XML node attributes. As a result, we show applicability of the approach through the following two examples: GUI Elements. This type of variability includes adding and removing whole GUI elements e.g. buttons, and text fields. These GUI elements can be singular, or can be containers of other GUI elements. This implementation variability can be used for implementing presentation units, UI element, and layout variability described in Sect. 2.2.2.
