extjs4 - Difference between Ext.widget() and Ext.ComponentQuery.query()? -

-

i have component created extends ext.window.window, i've given alias of 'widget.customereditor'. once i've created shown instance of component both of following pieces of code seem getting reference same thing:

ext.componentquery.query('customereditor')[0]; ext.widget('customereditor');

the problem when try execute close method on returned object. following work , closes window:

ext.componentquery.query('customereditor')[0].close();

while not work:

ext.widget('customereditor').close();

i'm wondering difference between 2 ways of querying?

after reading api docs found answer. turns out ext.widget not query existing instance of component in dom instead creates new instances of components xtype. ext.componentquery should used find existing instances of components.

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
