- """
- Applet are the main "application" running in the environment.
- They are filling the main area between the titlebar and the foot bar.
- When you make your own applet, you have to make it to inherit of that class
- so you have access to all the needed features.
- An applet can provide two other services:
- - A plugin
- - A settings page
- They need to be registered in the applet init function
- The system should not try to create more than one instance of an applet, but
- it is still a good practice to make sure your applet would not crash or create any
- problem if that happen.
- The main widget function (Draw and handle_event) will be run automatically part of the
- main loop of the environment. If you need asynchronous behavious, it is up to your
- applet to create its own thread and manage them.
- An applet should not try to write directly onto the screen, or trying to get access
- to the canvas of other widget which it does not own as thing can change without notice
- on that part and would break your applet.
- An applet can have a transparent background (and it is recommended until you need to control the background.)
- Still you can use the alpha channel to make the (potential) background picture lighter if needed.
