I want to add some buttons in ‘window’ header, instead of ‘X’.
Draggable property must be saved!

Answer 1

You can specify the tools(Ext.Panel.Tool) config for the window!

tools: [{
    type: 'refresh',
    tooltip: 'Refresh form Data',
    handler: function(event, toolEl, panel) {
      // refresh logic
    }
  },
  {
    type: 'help',
    tooltip: 'Get Help',
    handler: function(event, toolEl, panel) {
      // show help here
    }
  }
]

There are 25 predefined buttons but you can customize your own.
