ViewController can not listen beforerender event?

[cqul...@gmail.com]

hi.I am new to Deft JS, I try to listen a window's beforerender event in view config but I fail.

code:

control: {

        view: {

            beforerender: "onBeforerender"

        },

        submit: {

            click: "onButtonClickSubmit"

        }

}

log:

[I] Adding 'beforerender' listener to 'null'.

[I] Adding 'submit' component reference for selector: '#submit'.

[I] Adding component selector for: '#submit'.

can someone help me?

Yes, that's correct. The ViewController's view setup happens after the render event on Ext JS, and initialize on Touch. Deft supports both Ext and Touch, and those are the only events we can listen for to be sure that the child components exist (so control block component getters work, that all view listeners can be set up, and so on).

Out of curiosity, what are you trying to do? Just asking in case there's actually an easier way to do what you're looking for.

Hello Brian,

I have the same problem. I want to choose the language for the text button property in the beforerender event. In my function, I have this code :

    onSplitbuttonBeforeRender: function(abstractcomponent, options) {

        var lang = localStorage ? (localStorage.getItem('user-lang') || 'en') : 'en';

        abstractcomponent.iconCls = lang;

        if (lang == 'fr') {

            abstractcomponent.text = 'Français';

        } 

        else {

            abstractcomponent.text = 'English';

        } 

    },

How can I do that ?

Thanks,

Jean-Marc

Well, I added a listener for the beforerender in my view. Is it correct ?

Ext.define('MyApp.view.menu.Accordion', {
    ...

    requires: [ "MyApp.controller.MenuController" ],
    controller: "MyApp.controller.MenuController",

    listeners: {
        beforerender: function(abstractcomponent, options) {
            this.getController().onPanelRender(abstractcomponent, options);
        }
    },

    ...
});

Thanks,

Jean-Marc

Why do you need to change the text before render? You can just call button.setText('whatever') any time you want to change the text.
