Component Based UI

In ZK, we work with the UI components to assemble together our application GUI. Take the below for an example: ZKEssentials Intro Hello.png

Here we declared a Window component, enabled the border (border="normal"), and set its width to a definite 250 pixels. Enclosed in the Window is a Label component, which we set the background color to light blue and its font size to 20 pixels.

Where We Declare the Components

The components are declared in files with the extension ".zul". A ZUL page is interpreted dynamically at the server; we could think of it as a JSP empowered with Ajax capabilities.

How We Declare the Components

The language we use to declare the components is ZUML, an abbreviation for ZK UI Markup Language. ZUML follows the syntax of XML. We declare a component using a XML tag and set a component's initial value
