Toolbar

Toolbars contain different widgets like buttons, togglebuttons, radiobuttons oder (sub) menus. Generating and editing toolbars is analogue to menus.

Statusbar

The purpose of statusbars is to show notifications or useful information. Messages are treated like a list, the statusbar widget provides the functions push and pop.

Python

To send a message to the statusbar you will just need the function

widget.push(content_id,message)

If messages are exclusively shown "on top" the content_id can be a random number, like 0.
