Hello World Dialog

This example shows how to create a very simple modal BasicDialog with "autoTabs".



Note that the js is not minified so it is readable. See for the full source code.

Here's snapshot of the code that creates the dialog:
Roo.BLANK_IMAGE_URL  = "../../images/default/s.gif";



var HelloWorld = {

    dialog : false,
    callback:  false,

    show : function(data, cb)
    {
        // standard code example..
        if (!this.dialog) {
            this.create();
        }

        this.callback = cb;
        this.data = data;
        this.dialog.show(data._el ? data._el : false);
        if (this.form) {
           this.form.reset();
           this.form.setValues(data);
           this.form.fireEvent('actioncomplete', this.form,  { type: 'setdata', data: data });
        }

    },

    create : function()
    {
        var _this = this;
        this.dialog = Roo.factory({
            xns : Roo,
            xtype : 'LayoutDialog',
            autoTabs:true,
            width:500,
            height:300,
            shadow:true,
            minWidth:300,
            minHeight:250,
            proxyDrag: true,
            listeners : {
                show : function() {
                    var p = this.layout.getRegion('center').getPanel(0);
                    p.setContent("Hello World");
                    
                },
                keydown : function(dlg, e) {
                    var k = e.getKey(); 
                    if(k == 27){ _this.dialog.hide(); }  
                }
            },
            center : {
                xtype: 'LayoutRegion',
                xns: Roo
            },
            items : [
                {
                    xtype: 'Content',
                    xns: Roo.panel,
                    region : "center"
                    
                }
            ],
            buttons : [
                {
                    xtype : 'Button',
                    xns : Roo,
                    text : 'Submit',
                    listeners : {
                        click : function () {
                            _this.dialog.hide()
                        }   
                    }
                },
                {
                    xtype : 'Button',
                    xns : Roo,
                    text : 'Close',
                    listeners : {
                        click : function () {
                            _this.dialog.hide()
                        }   
                    }
                }
            ]
            
        });
            
    }
};                
 

// using onDocumentReady instead of window.onload initializes the application
// when the DOM is ready, without waiting for images and other resources to load
Roo.onReady(function() {
    
    Roo.get('show-dialog-btn').on('click',function () {
        HelloWorld.show({ _el : this});
    });
});
