ExtJS: check window state (is minimized, is maximized, etc)

ExtJS provides a number of configs as to whether a Window is configured as maximized, minimizable, etc. It also provides the functions to maximize and minimize a window.

Can't find however what the correct way to fetch an existing window state is. What I need is functions similar to the below:

var myWin = Ext.create('Ext.window.Window', { ... });
...
myWin.isMinimized(); // is current window minimized?
myWin.isMaximized(); // is current window maximized?

Can the current window's state be retrieved from the window instance?

One solution for anyone looking, instead of using minimizable config, use tools. Here is complete example..

var isMinimized = false;   //if you want to check for minimized elsewhere..
var winWidth;          //to restore to actual width.
Ext.create('Ext.window.Window', {
    title: 'Hello',
    closable : false,
    width : 300, height : 400,
     tools: [
                {  
                    type: 'restore',
                    hidden : true,
                    handler: function( evt,toolEl,owner,tool ) {
                        var window = owner.up( 'window' );
                        window.expand('',false);
                     window.setWidth(winWidth);
                        window.center();
                        isMinimized = false;
                        this.hide();
                        this.nextSibling().show();
                    }                                
                },{  
                    type: 'minimize',
                    handler: function( evt,toolEl,owner,tool ){
                        var window = owner.up( 'window' );
                        window.collapse();
                        winWidth = window.getWidth();
                        window.setWidth( 150 );
                        window.alignTo( Ext.getBody(), 'bl-bl');
                        this.hide();
                        this.previousSibling().show();
                        isMinimized = true;
                    }                                
                }                            
            ]
}).show();

@VisioN's answer is already complete but I want to show you a snippet using toggleCollapse() to hide the window:

Ext.create('Ext.Window',{
    height: 100,
    width: 100,
    minimizable: true,
    listeners: {
        minimize: function(){
            var win = this;
            win.toggleCollapse();
            if (!win.getCollapsed()) {
                win.center();
            } else {
                win.alignTo(document.body, 'bl-bl');
            }
        }
    }
}).show();

For maximize() there is a boolean property maximized which you can pick up from an object:

if (myWin.maximized) { ... }

However for minimize() ExtJS doesn't provide any functionality and expects individual implementation. Hence, there is no any minimized property supported from the box.
