""" An example of the `MainWindow` widget.

This example demonstrates the use of the `MainWindow` widget. This is a
subclass of the `Window` widget which adds support for dock panes, tool
bars and a menu bar. The children of a `MainWindow` can be defined in
any order. Like `Window`, a `MainWindow` has at most one central widget
which is an instance of `Container`. A `MainWindow` can have any number
of `DockPane` and `ToolBar` children, and at most one `MenuBar`.

Support for a `StatusBar` will be added in the future.

Implementation Notes:
    
    The main window facilities in Wx are very weak. If these features
    are required for a particular application, strongly prefer the Qt 
    backend over Wx (this is generally a good life-rule).
