Application Writing - WIN
An application program should only create local objects. The
application calls win.create_app_frame
to create an applicationFrame
window, which is the main frame and top object of the application.
The application code extends upon the frame object to define to
program.
A frame is always the work area size (the desktop not obscured by
the task bar). An application can only have one application frame
but can define any number of popupFrames. Each popupFrame can
also display a popupFrame.
Child windows, typically controls, are placed on these frame windows
to interact with the user and handle events.
The system runs by routing events to the appropriate application
thread and window for action. While the event handlers should be
employed to provide delays and keep sync, os.sleep may be used.
Lengthy processes should also be broken into sub-processes so event
handlers return in a reasonable time.
