Understanding UI Layouts

“Under Construction”

About this tutorial

In this tutorial we will see how to use UI Layouts to build Custom UI components. The target audience is for intermediate developers who have read through and understood the Getting Started with Lianja tutorial.

The Lianja App Development process

As you should recall from the Getting Started with Lianja tutorial, developing apps in the Lianja App Builder is an iterative process.

Let's just quickly review that process.

• You visually build a Lianja App using the Lianja App Builder. For non-programmers, the Lianja App Builder providers a wide range of pre-built templates to assist you in building an App quickly and easily.
• Lianja Apps are made up of Pages. Pages are made up of Sections. Sections are made up of Fields and Gadgets.
• You can group pages into Page Collections.

If you require to build a more complex App with a custom UI, you do this by building Custom Sections and/or Custom Gadgets in any of the following scripting languages which are integrated into the Lianja App Builder:

• Lianja/VFP
• JavaScript/TypeScript/Babel
• Python
• PHP

Seeing that the Lianja App Builder has an embedded database built into it, you do not need to install any other software to be able to build multi-user high performance database apps for the desktop, web and mobile devices.

The Lianja embedded database engine is highly compatible with Visual FoxPro. It includes a feature-complete cross platform implementation on the Visual FoxPro scripting and database engine.

Python, JavaScript, TypeScript, Babel and PHP are seamlessly integrated on top of this database engine, allowing you to build custom UI sections and custom UI gadgets in Visual FoxPro, JavaScript, TypeScript, Babel, Python or PHP and make full use of the power of this high performance database engine with local cursors and complete SQL and noSQL database support.

To facilitate the development of custom UI sections and gadgets, Lianja comes with a cross-platform, UI independent application framework called the Lianja UI Framework.
