Overview

Grid Gadgets can be loaded into a Form Section. They are used for displaying Google maps centered on a specified location. The location can be a fixed value or dynamically evaluated based on the current data.

You build Apps in Lianja App Builder visually using the Page Builder.

If you have not yet done so please read Understanding the Lianja Architecture and also Understanding ART to better understand this article.

An App consists of pages. Pages are made up of Sections. Form sections are made up of FormItems. We call these collectively "UI Elements" or "Visual Elements".

Setting Attributes Declaratively

You adjust the appearance and behavior of each UI Element in the Attributes Tab of the App Inspector.

Attributes


The attributes available consist of some common ones as well as some specific to the UI Element being inspected.

Getting and Setting Attributes Programmatically

The setAttribute(name, value) method can be used to set the value of an Attribute:

Lianja.get("pageid.sectionid.fieldid").setAttribute("caption","Formitem1")

Note: on the desktop, the shortened form setAttr(name,value) is also available.

The getAttribute(name) method can be used to get the value of an Attribute:

cTitle = Lianja.get("pageid.sectionid.fieldid").getAttribute("caption")

Note: on the desktop, the shortened form getAttr(name) is also available.
