Hey guys and Happy Easter,
I am working on an extension for the backend and would like to have the standard toolbar with save and cancel options in my own extension.
So I would like to have sth. like this:
I am kind of an newbie and would like to have a little more detailed answer.
Found something about addToolbarItem on the internet but don't know how to use it.
Edit:
Unfortunately I have to work with TYPO3 v4.5 and pibase extension and don't have enough time to change the version to 6.2.9...
Thanks!

Assuming you're using TYPO 6.x+ and Extbase!
You can put additional elements from your view to the layout by additional sections. most probably your view now looks like:
<f:layout name="Default"/>
<f:section name="content">
<h1>Foo</h1>
</f:section>
so add new section i.e.:
<f:layout name="Default"/>
<f:section name="myButtons">
<f:be.buttons.icon icon="actions-document-new" title="Create new Foo" />
</f:section>
<f:section name="content">
<h1>Foo</h1>
</f:section>
And finally in your Default.html layout render your section in proper place (set it as optional, otherwise you'll get an exception if missing!)
....
<div class="typo3-docheader-buttons">
<div class="left">
<f:render section="myButtons" optional="true"/>
</div>
<div class="right">
<span title="Reload" class="t3-icon t3-icon-actions t3-icon-actions-system t3-icon-system-refresh"> </span>
<f:be.buttons.shortcut />
</div>
</div>
....
Of course this way you can also set other elements like <f:be.menus.actionMenu>, <f:be.pageInfo /> etc, or even just your text labels.
