Summary

Building GUIs with the Delphi and FireMonkey libraries requires an understanding of the concept of a style. Styles in FireMonkey UI design play a similar role to cascading style sheets in web development.

Every FireMonkey app uses a style. This could be a built-in style or a custom style loaded from the TStyleBook component or an embedded resource. Integrated FireMonkey Style Designer lets us modify existing styles as easily as designing a form.

We have learned a lot about building UIs with FireMonkey. In the next chapter, we will go deeper into the rich world of different frameworks and components available on iOS and Android operating systems, and how FireMonkey helps us write cross-platform code that abstracts away the differences between different APIs.
