Ext.tree.plugin.TreeViewDragDrop

Defaults to: false

Available since: 4.0.0

Get the reference to the current class from which this object was instantiated. Unlike statics, this.self is scope-dependent and it's meant to be used for dynamic inheritance. See statics for a detailed comparison

Ext.define('My.Cat', {
    statics: {
        speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
    },

    constructor: function() {
        alert(this.self.speciesName); / dependent on 'this'

        return this;
    },

    clone: function() {
        return new this.self();
    }
});


Ext.define('My.SnowLeopard', {
    extend: 'My.Cat',
    statics: {
        speciesName: 'Snow Leopard'         // My.SnowLeopard.speciesName = 'Snow Leopard'
    }
});

var cat = new My.Cat();                     // alerts 'Cat'
var snowLeopard = new My.SnowLeopard();     // alerts 'Snow Leopard'

var clone = snowLeopard.clone();
alert(Ext.getClassName(clone));             // alerts 'My.SnowLeopard'

Parameters

  this

Call the original method that was previously overridden with override

Ext.define('My.Cat', {
    constructor: function() {
        alert("I'm a cat!");

        return this;
    }
});

My.Cat.override({
    constructor: function() {
        alert("I'm going to be a cat!");

        var instance = this.callOverridden();

        alert("Meeeeoooowwww");

        return instance;
    }
});

var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
                          // alerts "I'm a cat!"
                          // alerts "Meeeeoooowwww"

Available since: 4.0.0

Parameters

• args : Array/Arguments

  The arguments, either an array or the arguments object

Returns

• Object

  Returns the result after calling the overridden method

Call the parent's overridden method. For example:

Ext.define('My.own.A', {
    constructor: function(test) {
        alert(test);
    }
});

Ext.define('My.own.B', {
    extend: 'My.own.A',

    constructor: function(test) {
        alert(test);

        this.callParent([test + 1]);
    }
});

Ext.define('My.own.C', {
    extend: 'My.own.B',

    constructor: function() {
        alert("Going to call parent's overriden constructor...");

        this.callParent(arguments);
    }
});

var a = new My.own.A(1); // alerts '1'
var b = new My.own.B(1); // alerts '1', then alerts '2'
var c = new My.own.C(2); // alerts "Going to call parent's overriden constructor..."
                         // alerts '2', then alerts '3'

Available since: 4.0.0

Parameters

• args : Array/Arguments

  The arguments, either an array or the arguments object from the current method, for example: this.callParent(arguments)

Returns

• Object

  Returns the result from the superclass' method

The base implementation just sets the plugin's disabled flag to true

Plugin subclasses which need more complex processing may implement an overriding implementation.

Initialize configuration for this class. a typical example:

Ext.define('My.awesome.Class', {
    // The default config
    config: {

    },

    constructor: function(config) {
        this.initConfig(config);

        return this;
    }
});

var awesome = new My.awesome.Class({
    name: 'Super Awesome'
});

alert(awesome.getName()); // 'Super Awesome'

  this

Get the reference to the class from which this object was instantiated. Note that unlike self, this.statics() is scope-independent and it always returns the class from which it was called, regardless of what this points to during run-time

Ext.define('My.Cat', {
    statics: {
        totalCreated: 0,
        speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
    },

    constructor: function() {
        var statics = this.statics();

        alert(statics.speciesName);     // always equals to 'Cat' no matter what 'this' refers to
                                        // equivalent to: My.Cat.speciesName

        alert(this.self.speciesName);   // dependent on 'this'

        statics.totalCreated++;

        return this;
    },

    clone: function() {
        var cloned = new this.self;                      // dependent on 'this'

        cloned.groupName = this.statics().speciesName;   // equivalent to: My.Cat.speciesName

        return cloned;
    }
});


Ext.define('My.SnowLeopard', {
    extend: 'My.Cat',

    statics: {
        speciesName: 'Snow Leopard'     // My.SnowLeopard.speciesName = 'Snow Leopard'
    },

    constructor: function() {
        this.callParent();
    }
});

var cat = new My.Cat();                 // alerts 'Cat', then alerts 'Cat'

var snowLeopard = new My.SnowLeopard(); // alerts 'Cat', then alerts 'Snow Leopard'

var clone = snowLeopard.clone();
alert(Ext.getClassName(clone));         // alerts 'My.SnowLeopard'
alert(clone.groupName);                 // alerts 'Cat'

alert(My.Cat.totalCreated);             // alerts 3
