    Browser versions tested against:

    Code:
    show: function(animateTarget, cb, scope) {
            var me = this,
                rendered = me.rendered;
    
            //this is true on the first showAt
            if (rendered && me.isVisible()) {
                if (me.toFrontOnShow && me.floating) {
                    me.toFront();
                }
            } else if (me.fireEvent('beforeshow', me) !== false) {

                me.hidden = false;
                if (!rendered && (me.autoRender || me.floating)) {

                    rendered = me.rendered;
                }
                
                if (rendered) {
                    me.beforeShow();
                    me.onShow.apply(me, arguments);
                    me.afterShow.apply(me, arguments);

    We already have a report of this particular issue, should be fixed for 4.1.1. Thanks.

    This still doesn't work in 4.2.*

    Code:
    var comp = new Ext.Component({renderTo:Ext.getBody()});
    comp.on('beforeshow', function(){
        console.log('aye')
    })
    comp.showAt(0,0);
    Check out my small framework https://github.com/pllee/luc . I would love to get some feedback on it let me know what you think about it in a pm.

    In that test case it's already visible, so it's not going to fire before/show.

    Code:
    Ext.require('*');
    
    Ext.onReady(function() {
        var comp = new Ext.Component({
            html: 'Foo',
            autoRender: true
        });
        comp.on('beforeshow', function() {
            console.log('aye')
        });
        comp.showAt(0, 0);
    });
