Delphi Fmx Samples Info

1. Overview

Delphi FMX Samples are a collection of demo projects provided by Embarcadero (and the community) to illustrate the capabilities of the FireMonkey (FMX) framework. FMX is Delphi’s cross-platform GUI library for creating native applications on:

The samples showcase UI controls, graphics, animations, 3D, sensors, gestures, multi-touch, hardware integration, and backend services.

Learning path using samples

  1. Start with simple UI/control samples to learn FMX layout and styling.
  2. Move to input, multimedia, and sensors to understand platform services.
  3. Study networking and data samples for real-world app flows.
  4. Explore graphics/animation and custom painting for polished UX.
  5. Fork comprehensive sample apps and convert them into small production-grade prototypes.

Pitfall 3: Ignoring Threading Requirements

Do not call platform services (e.g., TLocationSensor) directly from a background thread. Samples that use TTask or TThread.Queue are safe. delphi fmx samples

2. Gesture-Controlled 3D Carousel

// Swipe to rotate 3D item carousel
procedure OnGesture(Sender: TObject; const EventInfo: TGestureEventInfo; var Handled: Boolean);

Part 7: Future-Proofing Your FMX Knowledge

Embarcadero releases new FMX features with every version:

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). Windows (64-bit, 32-bit) macOS iOS Android Linux (limited,

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.

What is Delphi FMX?

Delphi FMX is a set of libraries and tools for building cross-platform applications using the Delphi programming language. It provides a unified way to create GUI applications, leveraging the power of the Delphi language and the FireMonkey framework. The samples showcase UI controls, graphics, animations, 3D,

Part 3: Where to Find Official and High-Quality Delphi FMX Samples

Embarcadero has significantly improved its sample offerings. Here is your treasure map:

1. Particle System with Physics

// Animated particle system reacting to audio
TParticleEmitter = class
  procedure EmitParticle(Intensity: Single);
  procedure UpdateParticles(DeltaTime: Double);
end;

2.1 UI and Layout Samples

FMX uses a flexible layout system based on TAlign, TLayout, TGridPanelLayout, and TScaleLayout. Key samples to explore:

| Sample Name | What It Teaches | |-------------|------------------| | CustomListBox | Creating dynamic, styled list items | | MasterDetailDetail | Multi-level navigation on mobile | | TabControlTransitions | Animated swiping between tabs | | AdaptiveLayout | Changing UI orientation and size at runtime |

Code highlight – Adding a search filter to a TListView (excerpt from official sample):

procedure TForm1.SearchEditChangeTracking(Sender: TObject);
begin
  TListView(SearchHandle).Items.Filter := 
    function (Item: TListViewItem): Boolean
    begin
      Result := ContainsText(Item.Text, SearchEdit.Text);
    end;
end;
