I pasted in the Model and View classes for the list view based on the 2.5 Joomla Programming book with comments stripped out and generic names. In the view.html.php file there is a line:
Code:
JToolBarHelper::deleteList('', 'myitems.delete','JTOOLBAR_EMPTY_TRASH');
Which adds the delete functionality without a need to create a method. You'll notice in the model there is no reference to a delete method and there doesn't need to be one as it is part of the core.
Code:
$bar = JToolBar::getInstance('toolbar');
$bar->appendButton('Link', 'export', 'COM_MYEXAMPLE_TOOLBAR_CUSTOMDELETE',
'index.php?option=com_joomprosubs&task=myitems.mydelete');
This line would add your custom functionality for deleting to the toolbar icons.
ModelList is correct for the list view, but it looks like you are missing some methods. On a side note, ModelAdmin is the extended Joomla class for the single or detailed view and has its own set of methods you need to call.
A big thing to remember is that 2.5 depreciated a LOT of 1.5 functionality which shored up security and cleaned up the core. A result of this maturing of the code base was many of the shortcuts developers used to insert hand rolled classes and code snippets no longer work.
You have to think of 2.5 as an all or nothing approach, and in your defense; Joomla's online tutorials for 2.5 dwarf in detail and scope to the new Joomla Programming book. Which I might add is the ONLY reason I am able to integrate into Joomla 2.5.

I inserted this code snippet because it is VERY important to proper integration. There is a lot of navigation and management features which depend on database items having this foundation. When I write an extension, I always use this as the base for the table and add columns and fields needed for what I'm writing. Without these additional fields, integration won't work properly.
Again, if possible, spend the $30 bucks on the book which lays everything out for you!
