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:
 +
 
 +
<pre>Lianja.get("pageid.sectionid.fieldid").setAttribute("caption","Formitem1")</pre>
 +
 
 +
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:
 +
 
 +
<pre>cTitle = Lianja.get("pageid.sectionid.fieldid").getAttribute("caption")</pre>
 +

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

Overview

Listview Gadgets can be loaded into a Form Section. They provide a clickable list to select an option.

Listview gadget.png

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.
