23 the main event handling code. Normal use is to override the <code>__init__</code> routine
24 to do your own initializations and override <code>makeusermenus</code> to create your menus
26 The event handling code can be overridden at various levels, from very low-level (the
27 <code>dispatch</code> method) to intermediate level (<code>do_keyDown</code>, for instance)
28 to high-level (<code>do_key</code>). The application class knows about the <code>Window</code>
30 would have a <code>do_key</code> method in your window object, not your application object).
32 <dt> <CODE>MenuBar</CODE>, <CODE>Menu</CODE> and <CODE>MenuItem</CODE>
34 These classes (and a few friends like <CODE>SubMenu</CODE>) handle your menus. You would not
36 see the test code at the bottom of FrameWork for sample use. The apple menu is handled for you
37 by <CODE>MenuBar</CODE> and <CODE>Application</CODE>.

43 structure but actually opening the window is delayed until you call <code>open</code>. Your
44 open method should call <code>do_postopen</code> to let the base class handle linking in to
45 the application object. Similarly with <code>close</code> and <code>do_postclose</code>. The
46 rest of the code is mainly event-oriented: you override <code>do_postresize</code>,
47 <code>do_contentclick</code>, <code>do_update</code>, <code>do_activate</code>
48 and <code>do_key</code> to "do your thing". When these methods are called the relevant environment
49 has been setup (like <code>BeginDrawing</code> has been called for updates, etc).

66 …lass of ControlsWindow, a window with optional scrollbars. If you override <code>do_activate</code>
67 or <code>do_postresize</code> you must call the ScrolledWindow methods at the end of your override.
68 You call <code>scrollbars</code> to enable/disable scrollbars and <code>updatescrollbars</code> to
69 update them. You provide <code>getscrollbarvalues</code> to return the current x/y values (a helper
70 method <code>scalebarvalues</code> is available) and <code>scrollbarcallback</code> to update your
