2.9.2 Window Objects

Window objects have the following methods, among others:

`open`( | )

  Override this method to open a window. Store the MacOS window-id in `self.wid` and call the `do_postopen()` method to register the window with the parent application.

`close`( | )

  Override this method to do any special processing on window close. Call the `do_postclose()` method to cleanup the parent state.

`do_postresize`( | width, height, macoswindowid)

  Called after the window is resized. Override if more needs to be done than calling `InvalRect`.

`do_contentclick`( | local, modifiers, event)

  The user clicked in the content part of a window. The arguments are the coordinates (window-relative), the key modifiers and the raw event.

`do_update`( | macoswindowid, event)

  An update event for the window was received. Redraw the window.

`do_activate`( | activate, event)

  The window was activated (`activate == 1`) or deactivated (`activate == 0`). Handle things like focus highlighting, etc.
