6.17.1 Functions

The module `curses.panel` defines the following functions:

`bottom_panel`()
  Returns the bottom panel in the panel stack.

`new_panel`(win)
  Returns a panel object, associating it with the given window win.

`top_panel`()
  Returns the top panel in the panel stack.

`update_panels`()
  Updates the virtual screen after changes in the panel stack. This does not call `curses.doupdate()`, so you'll have to do this yourself.
