Question: Is there a way to query "up"? I'm in a Component and want to register listeners to it's parents events with control(). This requires a Query which gets me the parent of my main view.

Answer: 
In ExtJS4, you can use 'up()' from an Ext Element.

The params are a string of the parent element you wish to find e.g:

```
var parentEl = Ext.get('childID').up('div.parentClass'); 

```

If you provide some details about the structure of your components/elements I can give a specific example which should fit.

EDIT: To show going 'up' from a component

```
var myComponent = // however you've got it

var theParentEl = myComponent.getEl().up('div.parentClass');

```
Usually `up('PARENTCLASS')` is enough for what you're trying to do. Here is what I do all over the code so elements generates event for the form they are in:

```
items: [
...
   { xtype: 'checkbox', listeners: {
      change: function() { this.up('window').fireEvent('checkboxchanged'); }
   }}
...
]

```
