Declarative vs fluent

Mateu supports two main ways of building UIs in Java.

Declarative

In the declarative style, you describe the UI with:

• classes
• fields
• methods
• annotations

Best for

• forms
• CRUD screens
• fast development
• simple UIs

Fluent

In the fluent style, you build the UI with Mateu’s Java API.

Best for

• custom layouts
• advanced composition
• fine-grained control

Recommendation

Start with the declarative style.

Use the fluent style when you need more control.
