| Abstract base class required for all MillStone applications. This
class provides all the basic services required by the MillStone
framework. These services allow external discovery and manipulation of
the user,
org.millstone.base.ui.Window windows and
themes, and starting and stopping the application.
As mentioned, all MillStone applications must inherit this class.
However, this is almost all of what one needs to do to create a fully
functional MillStone application. The only thing a class inheriting the
Application needs to do is implement the init()
where it creates the windows it needs to perform its function. Note that
all MillStone applications must have at least one window: the main
window. The first unnamed window constructed by an application
automatically becomes the main window which behaves just like other
windows with one exception: when accessing windows using URLs the main
window corresponds to the application URL whereas other windows
correspond to a URL gotten by catenating the window's name to the
application URL.
See the class org.millstone.examples.HelloWorld for
a simple example of a fully working MillStone Application.
Window access. Application provides
methods to list, add and remove the windows it contains.
Execution control. This class includes method to
start and finish the execution of the application. Being finished means
basically that no windows will be available from the application
anymore.
Theme selection. The MillStone theme selection
process allows a theme to be specified at three different levels. When
a window's theme needs to be found out, the window itself is queried
for a preferred theme. If the window does not prefer a specific theme,
the application containing the window is queried. If neither the
application prefers a theme, the default theme for the
org.millstone.base.terminal.Terminal terminal is used. The
terminal always defines a default theme.
