QD

a geometric graphics package inspired by QBasic graphics

Methods:

• screen (int width, int height) : set screen size
• pset (int x, int y, rgb color) : set the color a pixel
• pget (int x, int y) : get the color of a pixel
• line (int x1, int y1, int x2, int y2) : draw a line
• cls () : clear the screen
• cls (rgb color) : set the whole screen to that color
• events (keyPressedDg = null, mouseEventDg = null, quitDg = null) : set up event callbacks. These take over the current thread.
• flip () : update the screen. By default, a hidden buffer is updated; flip displays the contents of that buffer.

Event records:

• key[char].pressed : returns true if the given key was pressed
• mouse.pressed (Button button) : returns true if the given button was pressed. Similar events include clicked, released, and moved.
