Copy&Paste from meego touch design guidelines:
"Use the toolbar for actions that are relevant to the content in focus. In landscape mode, the toolbar remains in a fixed position on top of the UI and in portrait mode, it is on the bottom of the UI.
Include the two to four most important commands (IconButtons) in the toolbar. Negative actions always sit on the right side of the toolbar."
This component needs an action based api for filling the contents of the toolbar.
