Top 10 Features of Embarcadero C++Builder XE8 You Should KnowEmbarcadero C++Builder XE8 remains a valuable tool for developers who need rapid application development (RAD) for Windows and mobile platforms. Released as part of the XE8 product line, C++Builder XE8 combined classic native Windows development with cross-platform capabilities powered by FireMonkey (FMX). Below are the top 10 features you should know, why they matter, and tips for getting the most from each.
1. FireMonkey (FMX) Cross-Platform Framework
What it is: FireMonkey is Embarcadero’s high-performance, GPU-accelerated UI framework that enables development of visually rich, cross-platform applications using a single codebase.
Why it matters:
- Build user interfaces that run on Windows, OS X (macOS), iOS, and Android (with varying levels of support in XE8).
- Hardware-accelerated rendering gives smoother animations and complex UI effects.
- Unified component model reduces duplicated UI work across platforms.
Tips:
- Design UI with device differences in mind (screen size, input methods).
- Use styles to maintain a consistent look across platforms.
- Profile GPU usage for graphic-heavy interfaces to preserve battery on mobile devices.
2. Native Code Compilation for Performance
What it is: XE8 compiles C++ to native machine code for supported platforms, ensuring high runtime performance.
Why it matters:
- Native executables typically run faster and use fewer resources than interpreted or VM-based apps.
- Better control over performance-critical sections and system-level integration.
Tips:
- Use compiler optimization settings for release builds.
- Leverage inline assembly or processor-specific intrinsics only when necessary and portable.
3. Live Preview and Device Deployment (Mobile Focus)
What it is: XE8 introduced improved tools for deploying to and previewing applications on mobile devices, including rapid iteration when testing on iOS devices.
Why it matters:
- Faster development cycles for mobile apps—deploy and test changes quickly.
- Ability to see how UI behaves on physical devices rather than relying solely on emulators.
Tips:
- Keep a physical test device for each major OS/version you plan to support.
- Use Live Preview to validate touch interactions and DPI scaling.
4. Enhanced RAD Studio Integration
What it is: C++Builder XE8 integrates tightly with RAD Studio, allowing shared projects, forms, and components with Delphi codebases.
Why it matters:
- Teams using Delphi can share libraries and components with C++Builder projects.
- Streamlines mixed-language projects and code reuse across teams.
Tips:
- Maintain clear module boundaries between Delphi and C++ units.
- Use shared packages (BPLs) for reusable components to avoid duplicate code.
5. Improved Debugging Tools
What it is: XE8 improved debugging features, including enhanced breakpoint controls, integrated memory and CPU profiling aids, and support for mobile debugging.
Why it matters:
- Easier to track down complex bugs, memory leaks, and performance bottlenecks across platforms.
- Mobile debugging support helps diagnose issues only reproducible on devices.
Tips:
- Use conditional breakpoints and watch expressions to minimize noise.
- Run profiling on release builds (with symbols) to get realistic performance data.
6. Component Library and Third-Party Ecosystem
What it is: A robust set of built-in VCL and FMX components plus a large third-party ecosystem for controls, libraries, and middleware.
Why it matters:
- Speeds development by providing prebuilt UI controls, data access components, and utilities.
- Third-party vendors offer specialized components (charts, grids, database tools) that would be time-consuming to build.
Tips:
- Vet third-party components for compatibility with XE8 and target platforms.
- Keep component libraries updated and isolated per-project to prevent DLL/BPL version conflicts.
7. REST Client and Mobile Backend Connectivity
What it is: XE8 includes components and support for RESTful services, JSON handling, and integration patterns suited for mobile backends.
Why it matters:
- Modern apps frequently rely on REST APIs and cloud backends; having built-in support simplifies development.
- JSON and REST components streamline data exchange and parsing.
Tips:
- Use asynchronous calls for network requests to keep UIs responsive.
- Implement robust error handling and offline caching where appropriate.
8. Improved Multi-Device Designer
What it is: The Multi-Device Designer in XE8 lets you design UI layouts for different target form factors and screen orientations from the same form.
Why it matters:
- Simplifies creating responsive interfaces for phones, tablets, and desktops.
- Reduces duplicated forms and visual logic across devices.
Tips:
- Define common layouts and use platform-specific tweaks sparingly.
- Test layouts in both portrait and landscape orientations for each target device.
9. Platform-Specific Services and Native API Access
What it is: XE8 exposes platform services and native APIs, allowing access to device features (GPS, camera, sensors) and OS-specific capabilities.
Why it matters:
- You can implement native-like features and integrations beyond basic UI.
- Enables richer applications that leverage hardware and OS services.
Tips:
- Abstract platform-specific code behind interfaces to keep core logic cross-platform.
- Manage permissions and privacy implications for device sensors carefully.
10. Productivity Enhancements and Code Insight
What it is: Editor and IDE improvements such as code completion, refactoring helpers, and project management features geared to speed up development.
Why it matters:
- Better IDE tooling reduces developer friction and helps maintain code quality.
- Code insight features help navigate large projects and avoid common errors.
Tips:
- Customize editor settings (formatting, templates) to match team conventions.
- Use built-in refactoring tools for safe, automated code changes.
Conclusion
Embarcadero C++Builder XE8 blends native C++ performance with rapid visual design and cross-platform reach. The FireMonkey framework, native compilation, improved mobile tooling, and strong IDE integration make XE8 particularly useful for teams that need to deliver visually rich, performant apps across desktop and mobile. By leveraging the component ecosystem, REST support, and platform services while following best practices for testing and abstraction, you can get the most from XE8 in both legacy and new projects.
