    Default Unanswered: Variables accessible from all controller functions? (MVC)

    Unanswered: Variables accessible from all controller functions? (MVC)


    Hey all,

    I'm using the MVC application structure. I've got a controller with quite a few functions in it. They all access a lot of the same components in my application but I think I've written it very inefficiently.

    For example, I have several buttons that affect the grid in my application. In each button function I have to do something like
    Code:
    var panel = button.up(panel);
    var grid = panel.down(grid);
    Instead of having those two lines in each button function, is there somewhere in the controller where I can define panel and grid (and the other components in my application) so they can be accessed by all my controller functions?

    thank you!

    You can try the references:

    Code:
    Ext.define('YourApp.controller.Main',{
        extend : 'Ext.app.Controller',
    
        refs : [
            {ref:'grid',selector:'acontainer anotherpanel grid[itemId=yourId]'}
        ],
    
        aFunction : function(){
            this.getGrid().getStore().load();
        }
    });
    First you define a reference with a selector, then you can access that reference by a dynamic method called "getYourReferenceName".

    These references are accesible only by the current controller.

    Regards

    Thank you, I've done some more reading about references now.

    So you can refer to specific instances of views in your app right? And once defined, calling a reference should be faster than doing a component query?
