Answer 1

Just like how you are setting the id, views or any other property. You only need to know that they named properties and not variables.

example:

//...
stores: ['InvoiceIdFromSession','Vats'], 
booleanVariable: true, 
stringVariable: 'demo',
floatVariable: .6,
objectVariable: { demo: 'test' }, 
id : 'poscontroller',
//...

Try this:

Ext.define('Ext4Example.controller.poscontroller', {
extend: 'Ext.app.Controller',
models: [
    'Vat',
    'Rebate',
    'Customer',
    'Product',
    'Invoice',
    'Item',
    'Order',
    'Paymethod'
],
stores: [
    'InvoiceIdFromSession',
    'Vats',
    'Rebates',
    'Customers',
    'Products',
    'Invoices',
    'Items',
    'Paymethods'
], //'Orders', ,'InvoiceIdFromSession','Products'
id : 'poscontroller',
views : [
    'stock.SaleWindow',
    'stock.ItemForm2',
    'stock.ItemsGrid',
    'stock.CalculationForm'
],
refs: [{
    ref: 'itemForm',
    selector: 'form'
}],

/*These are Global variables for this controller,
Now you can get and set these variable according to your need*/
config:{
    itemform  : Ext.getCmp('itemform2'),
    calculation_Form : Ext.getCmp('calculation-form'),
    ItemFrmdata : this.getItemform().getForm().getValues(),  // for get declared Variable
    calcFrmdata : this.getCalculation_Form().getForm().getValues()  // for get declared Variable
},
init: function() {

    this.control({
        'itemsgrid': {
            removeitem: this.removeUser
        },
        'salewindow button[action=resetAll]': {
            click: this.resertform
        },
        'salewindow button[action=saveOrder]' : {
            click : this.onsaveOrder
        },
        'salewindow button[action=PDF]' : {
            click : this. pdfreport
        }
    });
},
onsaveOrder : function(button){

}
});
