Delphi Fmx Samples [Must Try]

Never use absolute paths like C:\data.json in cross-platform samples. Replace with TPath.Combine(TPath.GetDocumentsPath, 'data.json') (requires System.IOUtils ).

When modifying sample code for production use, keep these three architectural strategies in mind:

Smooth UI transitions and graphical effects.

The VCL TListBox is too slow for 1,000+ items on mobile. TListView uses dynamic template recycling. Key sample: ListViewVirtualDemo (official) and ListViewPullToRefresh . Lesson learned: Never add items directly to ListView.Items . Instead, use TListBindSourceAdapter or TFDMemTable with LiveBindings. delphi fmx samples

The most reliable place to start is the official collection maintained by Embarcadero. These cover everything from basic UI to complex 3D and sensor integration. GitHub: Embarcadero FMX Samples

These community-driven projects are often cited in forums like Delphi-Praxis or Stack Overflow as the best real-world examples: FMXExpress

FMX uses a flexible layout system based on TAlign , TLayout , TGridPanelLayout , and TScaleLayout . Key samples to explore: Never use absolute paths like C:\data

Don't go digging through Google blindly. Here are the three best repositories:

These samples are crucial for mobile development. They show how to access native APIs using the System.iOS.Services or System.Android.Service units. Taking pictures and displaying them. Location Sample: Getting current GPS coordinates. 4. How to Effectively Use Delphi FMX Samples

FireMonkey (FMX) is Embarcadero Delphi's powerful cross-platform UI framework, enabling developers to build native applications for Windows, macOS, iOS, Android, and Linux from a single codebase. While the framework is robust, mastering it requires practical experience. are the fastest way to understand component behavior, styling, data binding, and platform-specific API access. The VCL TListBox is too slow for 1,000+ items on mobile

Many FMX apps are database front-ends. Key sample: FireDAC_FMX_Sample – connects TFDConnection to SQLite (local) or InterBase (server), then links to TListView via TBindSourceDB . Lesson learned: On iOS/Android, SQLite databases must be stored in TPath.GetDocumentsPath . The sample creates the database on first run if it doesn't exist.

The sample used absolute coordinates (e.g., Button.Width := 200 ). Fix: Look for samples that use TScaleLayout , TGridLayout , or AutoSize properties. Apply a TScaledLayout to the entire form and set its Scaled property to True .
