Exploring FireMonkey: A Guide to the Best Delphi FMX Samples

Delphi’s FireMonkey (FMX) framework is the powerhouse behind some of the most versatile cross-platform applications today. Whether you’re targeting Windows, macOS, iOS, Android, or Linux, the best way to master FMX is by diving into high-quality code samples.

Here is a curated look at the essential Delphi FMX samples and where to find them to kickstart your next project. 1. The Official RAD Studio Demo Repositories

The most reliable starting point is the official collection of demos provided by Embarcadero. These are updated for each major release, such as the RAD Studio 12 Demos on GitHub.

MultiView Demo: Learn how to create responsive navigation drawers that adapt perfectly to both mobile and desktop screens. delphi fmx samples

Photo Editor Demo: A great example of using built-in FMX effects and camera integration to build a functional utility app.

3D Objects & Animation: Explore FMX.FirstApp3D to see how to use components like TCamera, TCube, and TFloatAnimation to build hardware-accelerated 3D scenes. 2. Massive Community Collections: FMXExpress

For those who want a "one-stop-shop," the FMXExpress Cross-Platform Samples project is legendary. It contains over 100 demos that use a single codebase for all platforms.

Connectivity: Samples for Bluetooth, REST clients (using TFDMemTable), and local notifications. Exploring FireMonkey: A Guide to the Best Delphi

UI Components: Examples of modern mobile patterns like "Pull to Refresh," "Bottom Sheets," and "Drawer Menus".

Real-World Apps: Check out the BubbleChatApp or the ToDoList demo for end-to-end application architecture. 3. Specialized Game & UI Snippets

Delphi isn't just for business; it's surprisingly capable of 2D and 3D game development. FMX.MultiViewDemo Sample - RAD Studio Code Examples


1.3 GetIt Package Manager

Inside the Delphi IDE, go to Tools > GetIt Package Manager. Search for "Samples" or "FMX Demos". You will find curated packages such as: FMXExpress Samples – A collection of 50+ business-focused

  • FMXExpress Samples – A collection of 50+ business-focused FMX demos.
  • RAD Server FMX Client Samples – For backend-connected mobile apps.

Part 7: Future-Proofing Your FMX Knowledge

Embarcadero releases new FMX features with every version:

  • Delphi 12 Athens: Added TGrid (spreadsheet-like control), TWindow (multi-window on mobile), and Skia4Delphi integration.
  • Delphi 11 Alexandria: Improved high-DPI and TControl virtual methods.

To stay current, you need themed samples that target the latest API levels. Subscribe to the Embarcadero GitHub repository and follow FMX experts on LinkedIn (e.g., Jim McKeeth, Marco Cantù, Ian Barker).

Also, explore Skia4Delphi samples – a separate library that replaces FMX's default canvas with Skia (Google's 2D graphics library). The Skia samples are excellent for custom UI rendering.

Best practices and common pitfalls demonstrated by samples

  • Use responsive layouts and anchors rather than fixed positions to handle varying screen sizes.
  • Avoid heavy work on the UI thread; use background tasks (TTask) and synchronize updates to the UI.
  • Prefer FireDAC and high-level APIs for database and REST interactions to minimize platform differences.
  • Manage resources explicitly (bitmaps, timers) to avoid leaks, especially on mobile platforms.
  • Use conditional compilation (IFDEFs) sparingly and encapsulate platform-specific code behind interfaces.
  • Test on real devices—emulators often miss hardware or permission-related issues.
