Hi,
Child controls are managed internally by widget class. To create child
controls you must override widget method *_createChildControlImpl*, add your
child controls and call the base class *_createChildControlImpl* method:
*qx.Class.define('myapp.MyWidget', {
> *
* extend: qx.ui.core.Widget,
> *
>
* constructor: function() {
> *
* // first time it creates the statusbar and returns it
> this.getChildControl('statusbar');
> *
* // next times it will just return it
> var statusbar = this.getChildControl('statusbar');
> *
* },
> *
* members: {
> *
* // override
> _createChildControlImpl: function(id) {
> var control;
> *
* switch (id) {
> // If ID is 'statusbar' create statusbar child control
> case 'statusbar':
> control = new myapp.Statusbar();
> control.set({
> // some properties
> });
> break;
> *
* // More cases
> }
> *
* // If a control was created return the control, else call base class
> method
> return control || this.base(arguments, id);
> }
> }
> });*
*
*
