## pygame.constants

These constants are defined by SDL, and needed in pygame. Note that many of the flags for SDL are not needed in pygame, and are not included here. These constants are generally accessed from the pygame.locals module. This module is automatically placed in the pygame namespace, but you will usually want to place them directly into your module's namespace with the following command, 'from pygame.locals import *'.

display | - The following constants are used by the display module and Surfaces
events | - These constants define the various event types
keyboard | - These constants represent the keys on the keyboard.
modifiers | - These constants represent the modifier keys on the keyboard.
time | - These constants define the various time constants

display
`pygame.constants.display (constants)`

HWSURFACE - surface in hardware video memory. (equal to 1)
RESIZABLE - display window is resizeable
ASYNCBLIT - surface blits happen asynchronously (threaded)
OPENGL - display surface will be controlled by opengl
HWPALETTE - display surface has animatable hardware palette entries
DOUBLEBUF - hardware display surface is page flippable
FULLSCREEN - display surface is fullscreen (nonwindowed)
RLEACCEL - compile for quick alpha blits, only set in alpha or colorkey funcs
NOFRAME - no window decorations

events
`pygame.constants.events (constants)`

NOEVENT - no event, represents an empty event list, equal to 0
ACTIVEEVENT - window has gain/lost mouse/keyboard/visiblity focus
KEYDOWN - keyboard button has been pressed (or down and repeating)
KEYUP - keyboard button has been released
MOUSEMOTION - mouse has moved
MOUSEBUTTONDOWN- mouse button has been pressed
MOUSEBUTTONUP - mouse button has been released
JOYAXISMOTION - an opened joystick axis has changed
JOYBALLMOTION - an opened joystick ball has moved
JOYHATMOTION - an opened joystick hat has moved
JOYBUTTONDOWN - an opened joystick button has been pressed
JOYBUTTONUP - an opened joystick button has been released
VIDEORESIZE - the display window has been resized by the user
QUIT - the user has requested the game to quit
SYSWMEVENT - currently unsupported, system dependant
USEREVENT - all user messages are this or higher
