How to Use GXT XTemplate with ListView

XTemplate is a very useful class of GXT that supports auto-filling arrays, conditional processing with basic comparison operators, sub-templates, basic math function support, special built-in template variables, inline code execution and more. Here i am going to illustrate how to use XTemplate with a ListView to customize the look and feel of the ListView.

Create a new project named XTemplateExample and add GXT library in the project. To create a ListView at first you need a base model class and have to generate data for that model. In this tutorial i have used the same Employee model and TestData class for generating data which I have used in my previous blogs. You will find the code of these classes here.

Now go to the onModuleLoad method of XTemplateExample class. Remove all the auto generated code of this method.
First create a ListStore of Employee model , employeeList and add data to this store which was generated in the TestData class

  ListStore<Employee> employeeList = new ListStore<Employee>(); 

Now Create a ListView of Employee type and set the employeeList as the store of the list view.
   ListView<Employee> lView = new ListView<Employee>();
   //getTemplate() returns the desired template

   ContentPanel cp = new ContentPanel(); 
   cp.setHeading("Using XTemplate"); 
   cp.setLayout(new FitLayout()); 
   cp.setSize(500, 420);

Here goes the definition of the getTemplate() method
private native String getTemplate() /*-{ 
       return ['<tpl for=".">', 
       '<div style="border: 1px solid #DDDDDD;float:left;margin:4px 0 4px  4px; padding:2px;width:220px;">',
       '<div style="color:#1C3C78;font-weight:bold;padding-bottom:5px;padding-top:2px;text-decoration:underline;">{name}</div>', 
       '<div style="color:green">Department:{department}</div>', 
       '<div style="color:blue">Designation:{designation}</div>',
       '<div style="color:black;padding-bottom:2px;">Salary:{salary}</div>', 

Properties of the Employee model are placed between {}. The style will be applied on every element of the employeeList. And the outcome of the work will be like this.

You can give your own look and feel by simply changing the CSS.

I spent days looking for a valid template example using the ListView instead of the deprecated DataView. Being new to GWT, this was a very helpful post. Thank you very much!
