Serve the menu

Menu

The menu widget is part of the container widgets but itself needs an empty box to be placed in. There can be generated a standard menu that is easily edited after clicking on "Edit..." in a separate window.

Creating shortcuts is also simple. In the "Edit" window a click on "Hierarchy > Properties > Accelerators" opens a dialogue in which a shortcut is assigned to a signal (regarding menu items you want to assign activate).

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.
