Question

I am using Extjs for my application. Which event/listener is fired when extjs completely loads the application (images and everything)?

I tried following but none of these worked:

• body or window onload (body tag is empty)
• viewport render listener

What I am doing currently: When I start the application it displays “loading” mask. Then an ajax request is fired and when it is completed, “loading” mask is removed. Following might give some idea:

Ext.onReady(function(){
    Ext.ux.mask = new Ext.LoadMask(Ext.getBody(), {msg: "Loading..."});
    Ext.ux.mask.show();   // Show the mask

    // All components are loaded eg. viewport, tabpanel, button etc...
    ajax_request(); // Somewhere between the code ajax request is called
    // All components are loaded eg. viewport, tabpanel, button etc...

    function ajax_request() {
        // Other processing

        Ext.ux.mask.hide(); // Hide the mask
    }
});

The problem is the ajax request is taking much time now so i want to change the working something as follows:

Ext.onReady(function(){
    Ext.ux.mask = new Ext.LoadMask(Ext.getBody(), {msg: "Loading..."});
    Ext.ux.mask.show();   // Show the mask

    // All components are loaded eg. viewport, tabpanel, button etc...
    ajax_request(); // Somewhere between the code ajax request is called
    // All components are loaded eg. viewport, tabpanel, button etc...

    function ajax_request() {
        // Other processing

        //Ext.ux.mask.hide();   // Hide the mask - removed
    }

    // I want to call this when everything is loaded on the page
    function everything_loaded() {
        Ext.ux.mask.hide(); // Hide the mask
    }

});

Any idea on this? Thanks a lot for help.

Thanks to amol and Warung Nasi 49. Although I couldn’t find the best way, I manage to get almost expected result:

Ext.onReady(function(){
    Ext.ux.mask = new Ext.LoadMask(Ext.getBody(), {msg: "Loading..."});
    Ext.ux.mask.show();   // Show the mask

    // All components are loaded eg. viewport, tabpanel, button etc...

    setTimeout(function(){
        Ext.ux.mask.hide(); 
    }, 2000);

});
