    Default Touch 2.0.0.pr3 and Ext.draw.Component

    Touch 2.0.0.pr3 and Ext.draw.Component


    I'm trying to port an existing piece of code that worked using "Ext.draw.component" to work with Touch 2pr3. However, things don't look promising here. Specifically:

    Rendering a widget using
    Code:
    Ext.create('Ext.draw.Component')
    results in a huge pile of deprecation warnings:

    [DEPRECATE][Ext.draw.Component#constructor] onRender() is deprecated, please put your code inside initialize() insteadsencha-touch-all-debug.js:21340[DEPRECATE][Ext.draw.Component#createSurface] 'el' is deprecated, please use 'element' insteadsencha-touch-all-debug.js:21340[DEPRECATE][Ext.draw.Surface.create] Ext.supports.Svg is deprecated, please use Ext.feature.has.Svg insteadsencha-touch-all-debug.js:21340[DEPRECATE][Ext.draw.Surface.create] Ext.supports.Vml is deprecated, please use Ext.feature.has.Vml insteadsencha-touch-all-debug.js:21340[DEPRECATE][Ext.draw.Component#constructor] initComponent() is deprecated, please put your code inside initialize() insteadsencha-touch-all-debug.js:21340[DEPRECATE][Ext.draw.Component#addEvents] addEvents() is deprecated. It's no longer needed to add events before firing

    and subclassing it, like I used to do in ExtJS4:
    Code:
    Ext.define('My.Draw',{
    
    
        extend: 'Ext.draw.Component',
    
    
        config: {
            width:          640,            // width of the draw.Component
            height:         480,            // height of the draw.Component
    
    
            ...
        },
    
    
        constructor: function(cfg) {
    
    
            this.initConfig();
    ...
        }
    results in getting lost in:

    Uncaught TypeError: Cannot call method 'setWidth' of nullExt.define.doSetWidthsencha-touch-all-debug.js:37766(anonymous function)sencha-touch-all-debug.js:29640Base.implement.initConfigsencha-touch-all-debug.js:2845Ext.define.constructor...


    Seeing this, I got the impression, that the "Ext.draw" tree of Touch is not really usable at this time (in pr3). Am I right?

    And: If so, do you have an advise on how to proceed or what to wait for?

    PR stages so expect a bumpy road still. Not sure why you are calling initConfig in the constructor, ST2 will do this for you.
