Ext JS 4 - Form Panel With Menubar

The form panel (Ext.form.Panel) class in Ext JS is used for creating form. The default layout of the form panel is anchor. It has lot options for customization, in that one of the feature is menu bar. The following properties are used for including menu into form panel. 

  1. tbar - Top Bar
  2. bbar - Bottom Bar
  3. lbar - Left Bar
  4. rbar - Right Bar

Let's see an example for creating form panel with menu bar.

Ext.define('MyApp.view.PanelWithMenuBar', {
 extend : 'Ext.form.Panel',
 alias : 'widget.panelwithtoolbar',
 layout : 'anchor',
 height : 400,
 width : 400,
 title : 'Form Panel with Menubar',
 url : '/saveform',
 tbar : [{
  text : 'Top-Left Menu',
  menu : [{
   text : 'User',
   menuKey : 'top-left-create-user'
  }, {
   text : 'Document',
   menuKey : 'top-left-create-document'
  }, {
   text : 'Profile',
   menuKey : 'top-left-create-profile'
  }]
 }, '->', {
  text : 'Top-Right Menu',
  menu : [{
   text : 'User',
   menuKey : 'top-right-create-user'
  }, {
   text : 'Document',
   menuKey : 'top-right-create-document'
  }, {
   text : 'Profile',
   menuKey : 'top-right-create-profile'
  }]
 }],
 bbar : [{
  text : 'Bottom-Left Menu',
  menu : [{
   text : 'User',
   menuKey : 'bottom-left-create-user'
  }, {
   text : 'Document',
   menuKey : 'bottom-left-create-document'
  }, {
   text : 'Profile',
   menuKey : 'bottom-left-create-profile'
  }]
 }, '->', {
  text : 'Bottom-Right Menu',
  menu : [{
   text : 'User',
   menuKey : 'bottom-right-create-user'
  }, {
   text : 'Document',
   menuKey : 'bottom-right-create-document'
  }, {
   text : 'Profile',
   menuKey : 'bottom-right-create-profile'
  }]
 }],
 items : [{
  xtype : 'textfield',
  fieldLabel : 'First Name',
  name : 'firstName',
  allowBlank : false
 }, {
  xtype : 'textfield',
  fieldLabel : 'Last Name',
  name : 'lastName',
  allowBlank : false
 }],
 renderTo : Ext.getBody()
});

Here the symbol '→'  is used for moving our menu from left to right side.

Here I have included menuKey attribute, this is custom attribute included for taking handle of the menu actions in controller side. Let's see, how to take a control of form panel and corresponding form menu actions in controller. This is very tricky part when you are in beginning stage and this is my controller code for above view.

Ext.define('MyApp.controller.PanelWithMenuBar', {
 extend : 'Ext.app.Controller',
 init : function() {
  this.control({
   'menuitem[menuKey]' : {
    click : function(menuItem, e, eOpts) {
     switch(menuItem.menuKey) {
      case 'top-left-create-user' :
       console.log('Event related to top-left-create-user');
       break;
      case 'top-left-create-document' :
       console.log('Event related to top-left-create-document');
       break;
      case 'top-left-create-profile' :
       console.log('Event related to top-left-create-profile');
       break;
      case 'bottom-right-create-user' :
       console.log('Event related to bottom-right-create-user');
       break;
      case 'bottom-right-create-document' :
       console.log('Event related to bottom-right-create-document');
       break;
      case 'bottom-right-create-profile' :
       console.log('Event related to bottom-right-create-profile');
       break;
      //Other menukey actions will goes here.....
     }
    }
   }
  });
  this.callParent(arguments);
 }
});

During rendering of an application, the Ext JS will create an object of 'Ext.menu.Item' for tbar, lbar, bbar, and rbar based on its configuration. So I can take a control of all menu items by using xtype and menuKey.

menuitem[menuKey] - Here menuitem refer the xtype of 'Ext.menu.Item' and menuKey is our custom attribute.

The result of above example is given below.

Ext JS 4 – Creating web page using Ext.container.Viewport class and region propery

The Ext.container.Viewport is used for creating general web page and region property is used for splitting web page into different parts. Ext.container.Viewport is a specialized container represents the viewable area of the application (the browser area). It render itself to the document body, there is no need for providing renderTo property and it automatically sizes itself to size of the browser viewport. The viewport also re-size the child elements based on view area(based on browser width and height). The default layout of the viewport is border layout and we can customize this property according to our requirements. The viewport does not provide any scrolling. If necessary, the child elements(generally panels) within viewport needs to provide a scroll feature by using autoScroll property. See the below example for better understanding. This is Home.js file placed into app/view folder. Ext.define('MyApp.view.Home', { extend : 'Ext.container.Viewport&#

Simple Login Application Using Spring MVC and Hibernate – Part 1

 I hope developers working in web application development might hear about MVC architecture. Almost all technologies provide support for MVC based web application development, but the success is based on many factors like reusable of the code, maintenance of the code, future adaption of the code, etc..,  The success of the Spring MVC is “ Open for extension and closed for modification ” principle. Using Spring MVC the developers can easily develop MVC based web application. We don’t need any steep learning curve at the same time we need to know the basics of spring framework and MVC architecture. The Spring MVC consists of following important components. 1.
