Note: This applies when using the MVC structure.

By default the Joomla Toolbar uses a Delete, Edit, New, Publish, Unpublish and Parameters buttons. To use them in your component you must write the following code in the view.html.php of your view file (below your display function). 

      JToolBarHelper::title( 'your_component_view_page_title', 'generic.png' );
      JToolBarHelper::deleteList(); // Will call the task/function "remove" in your controller
      JToolBarHelper::editListX(); // Will call the task/function "edit" in your controller
      JToolBarHelper::addNewX(); // Will call the task/function "add" in your controller
      JToolBarHelper::publishList(); // Will call the task/function "publish" in your controller
      JToolBarHelper::unpublishList(); // Will call the task/function "unpublish" in your controller
      JToolBarHelper::preferences('your_component_xml_file', 'height');

So (i.e.) your code would look like this: 

 class HelloViewHellos extends JView
 {
   function display($tpl = null) {
      global $mainframe, $option;
      JToolBarHelper::title( 'Hello Component', 'generic.png' );
      JToolBarHelper::deleteList();
      JToolBarHelper::editListX();
      JToolBarHelper::addNewX();
      JToolBarHelper::publishList();
      JToolBarHelper::unpublishList();
      JToolBarHelper::preferences('com_hello', '500');

An example of creating a custom button in the admin list of records of your component Joomla 3.0 could be:


administrator/views/hellos/view.html.php 

        public function display($tpl = null)
        {
 
                $this->state            = $this->get('State');
                $this->items            = $this->get('Items');
                $this->pagination       = $this->get('Pagination');
 
                // Check for errors.
                if (count($errors = $this->get('Errors'))) {
                        JError::raiseError(500, implode("\n", $errors));
                        return false;
                }
 
                $this->addToolbar();
 
                $this->sidebar = JHtmlSidebar::render();
                parent::display($tpl);
 
        }
 
        protected function addToolbar()
        {
                // assuming you have other toolbar buttons ...
 
                JToolBarHelper::custom('hellos.extrahello', 'extrahello.png', 'extrahello_f2.png', 'Extra Hello', true);
 
        }

administrator/controllers/hellos.php 

    public function extrahello()
        {
 
                // Get the input
                $input = JFactory::getApplication()->input;
                $pks = $input->post->get('cid', array(), 'array');
 
                // Sanitize the input
                JArrayHelper::toInteger($pks);
 
                // Get the model
                $model = $this->getModel();
 
                $return = $model->extrahello($pks);
 
                // Redirect to the list screen.
                $this->setRedirect(JRoute::_('index.php?option=com_hello&view=hellos', false));
 
        }

administrator/models/hello.php (note: the singular model) 

    public function extrahello($pks)
        {
 
                // perform whatever you want on each item checked in the list
 
                return true;
 
        }
