data Event Source #

High level event structure.

MouseButtonDown !Word16 !Word16 !MouseButton 
MouseButtonUp !Word16 !Word16 !MouseButton 
JoyAxisMotion !Word8 !Word8 !Int16

device index, axis index, axis value.

JoyBallMotion !Word8 !Word8 !Int16 !Int16

device index, trackball index, relative motion.

JoyHatMotion !Word8 !Word8 !Word8

device index, hat index, hat position.

JoyButtonDown !Word8 !Word8

device index, button index.

JoyButtonUp !Word8 !Word8

device index, button index.

VideoResize !Int !Int

When Resizable is passed as a flag to setVideoMode the user is allowed to resize the applications window. When the window is resized an VideoResize is reported, with the new window width and height values. When an VideoResize is recieved the window should be resized to the new dimensions using setVideoMode.

VideoExpose

A VideoExpose event is triggered when the screen has been modified outside of the application, usually by the window manager and needs to be redrawn.
