Question

This is the code im using and im firing button click event once the window show event is called. this works fine. but how to do the same without using Ext.getCmp

this is the line

Ext.getCmp('recent_refresh').fireEvent('click');

this is the code

 Ext.create('widget.window', {
      title: 'Activity',
      closable: true,
      closeAction: 'hide',
      width: 250,
      height: 300,
      bodyBorder: true,
      tbar: {
          xtype: 'toolbar',
          ui: 'plain',
          items: [{
              iconCls:'refresh',
              id: 'recent_refresh',
              listeners: {
                click: function(){ 
                      Ext.Ajax.request({
                          url: 'control.php',
                          params: {
                              'case': '18'
                          },
                          success: function(response){
                              var json =  Ext.decode(response.responseText);

                          }
                      });               
                }  
              }
          },
          '->',
          {
              xtype: 'displayfield',
              name: 'act_date',
              id: 'act_date',
              value: new Date(),
              formatValue: Ext.util.Format.dateRenderer('Y-m-d')
          }]
      },      
      layout:'accordion',
      border: false,
      items: [ grid1, grid2, grid3 ],
      listeners: {
            show: function() {      Ext.getCmp('recent_refresh').fireEvent('click'); }        
      }

}).show();

There are many ways to do this. One way is to make an assignment with the Ext.create call since Ext.create returns such a reference. The app namespace in the example below is a filler since any namespaces you are using are unknown from your text. Once you have the variable reference to the widget, you can get use it to get a reference to the top toolbar and then get a reference to the item you want inside of the toolbar.

    Ext.ns('app');
    app.activityWin = Ext.create('widget.window', {...}
    app.activityWin.getTopToolbar().get('recent_refresh').fireEvent('click');
