show specific actions for the clicked object
add an edit button for tooltips
extend the specific actions'view

we extend them to images and tooltips.
For images we changed the Extend, we put the objectView
like other objects.
For tooltips, we added the event because in tooltip we
modify events, so we have to add the one that changes the actions view.
