Lianja includes an extensive array of built-in classes that are cross platform and cross device. If you need to build a custom Form UI these are for you.

If you are a VFP developer you will recognize some of these as Lianja has a powerful UI framework which is a superset of the VFP 9 base classes.

The Lianja UI Framework is client agnostic. Desktop, Web and Mobile.

If you are familiar with the VFP UI classes and you want to develop in JavaScript, TypeScript, Python or PHP you will feel right at home with a minimum learning curve compared to other App platforms.

Pro Tip

We recommend you use Lianja UI Layouts to help you build a responsive UI. These can be used in any of the supported scripting languages.

The following Base classes are built into Lianja. These are not specific to the LianjaScript/VFP scripting language but rather they can be used by all of the supported scripting languages. For case sensitive scripting languages use lowercase names for properties, methods and events.

Notice how the usage is consistent across all supported scripting languages.

We recommend using the Lianja built-in bootstrap compatible classes to consistently skin your UI. See Built-in CSS classes for details.

LianjaScript usage

oCont = createObject("container")
oCont.layout = "Vertical"
oCont.addObject("oLabel", "label")
oLabel.caption = "Hello World!"
 
// example event assignment. Event handlers can be assigned to an object
proc click()
    // your event handler code
endproc
 
oLabel.click = click
