Serialized Form

g

PGraphics g

The PGraphics renderer associated with this PApplet

frame

java.awt.Frame frame

The frame containing this applet (if any)

screen

java.awt.Dimension screen

The screen size when the applet was started.

Access this via screen.width and screen.height. To make an applet run at full screen, use size(screen.width, screen.height).

If you have multiple displays, this will be the size of the main display. Running full screen across multiple displays isn't particularly supported, and requires more monkeying with the values. This probably can't/won't be fixed until/unless I get a dual head system.

Note that this won't update if you change the resolution of your screen once the the applet is running.

This variable is not static, because future releases need to be better at handling multiple displays.

recorder

PGraphics recorder

A leech graphics object that is echoing all events.

args

java.lang.String[] args

Command line options passed in from main().

This does not include the arguments passed in to PApplet itself.

sketchPath

java.lang.String sketchPath

Path to sketch folder

defaultSize

boolean defaultSize

true if no size() command has been executed. This is used to wait until a size has been set before placing in the window and showing it.

resizeRequest

boolean resizeRequest

resizeWidth

int resizeWidth

resizeHeight

int resizeHeight

pixels

int[] pixels

Pixel buffer from this applet's PGraphics.

When used with OpenGL or Java2D, this value will be null until loadPixels() has been called.

width

int width

width of this applet's associated PGraphics

height

int height

height of this applet's associated PGraphics

mouseX

int mouseX

current x position of the mouse

mouseY

int mouseY

current y position of the mouse

pmouseX

int pmouseX

Previous x/y position of the mouse. This will be a different value when inside a mouse handler (like the mouseMoved() method) versus when inside draw(). Inside draw(), pmouseX is updated once each frame, but inside mousePressed() and friends, it's updated each time an event comes through. Be sure to use only one or the other type of means for tracking pmouseX and pmouseY within your sketch, otherwise you're gonna run into trouble.

pmouseY

int pmouseY

Previous x/y position of the mouse. This will be a different value when inside a mouse handler (like the mouseMoved() method) versus when inside draw(). Inside draw(), pmouseX is updated once each frame, but inside mousePressed() and friends, it's updated each time an event comes through. Be sure to use only one or the other type of means for tracking pmouseX and pmouseY within your sketch, otherwise you're gonna run into trouble.

dmouseX

int dmouseX

previous mouseX/Y for the draw loop, separated out because this is separate from the pmouseX/Y when inside the mouse event handlers.

dmouseY

int dmouseY

previous mouseX/Y for the draw loop, separated out because this is separate from the pmouseX/Y when inside the mouse event handlers.

emouseX

int emouseX

pmouseX/Y for the event handlers (mousePressed(), mouseDragged() etc) these are different because mouse events are queued to the end of draw, so the previous position has to be updated on each event, as opposed to the pmouseX/Y that's used inside draw, which is expected to be updated once per trip through draw().

emouseY

int emouseY

pmouseX/Y for the event handlers (mousePressed(), mouseDragged() etc) these are different because mouse events are queued to the end of draw, so the previous position has to be updated on each event, as opposed to the pmouseX/Y that's used inside draw, which is expected to be updated once per trip through draw().

firstMouse

boolean firstMouse

Used to set pmouseX/Y to mouseX/Y the first time mouseX/Y are used, otherwise pmouseX/Y are always zero, causing a nasty jump.

Just using (frameCount == 0) won't work since mouseXxxxx() may not be called until a couple frames into things.

mouseButton

int mouseButton

Last mouse button pressed, one of LEFT, CENTER, or RIGHT.

If running on Mac OS, a ctrl-click will be interpreted as the righthand mouse button (unlike Java, which reports it as the left mouse).

mousePressed

boolean mousePressed

mouseEvent

java.awt.event.MouseEvent mouseEvent

key

char key

Last key pressed.

If it's a coded key, i.e. UP/DOWN/CTRL/SHIFT/ALT, this will be set to CODED (0xffff or 65535).

keyCode

int keyCode

When "key" is set to CODED, this will contain a Java key code.

For the arrow keys, keyCode will be one of UP, DOWN, LEFT and RIGHT. Also available are ALT, CONTROL and SHIFT. A full set of constants can be obtained from java.awt.event.KeyEvent, from the VK_XXXX variables.

keyPressed

boolean keyPressed

true if the mouse is currently pressed.

keyEvent

java.awt.event.KeyEvent keyEvent

the last KeyEvent object passed into a mouse function.

focused

boolean focused

Gets set to true/false as the applet gains/loses focus.

online

boolean online

true if the applet is online.

This can be used to test how the applet should behave since online situations are different (no file writing, etc).

millisOffset

long millisOffset

Time in milliseconds when the applet was started.

Used by the millis() function.

frameRate

float frameRate

The current value of frames per second.

The initial value will be 10 fps, and will be updated with each frame thereafter. The value is not instantaneous (since that wouldn't be very useful since it would jump around so much), but is instead averaged (integrated) over several frames. As such, this value won't be valid until after 5-10 frames.

frameRateLastNanos

long frameRateLastNanos

Last time in nanoseconds that frameRate was checked

frameRateTarget

float frameRateTarget

As of release 0116, frameRate(60) is called as a default

frameRatePeriod

long frameRatePeriod

looping

boolean looping

redraw

boolean redraw

flag set to true when a redraw is asked for by the user

frameCount

int frameCount

How many frames have been displayed since the applet started.

This value is read-only do not attempt to set it, otherwise bad things will happen.

Inside setup(), frameCount is 0. For the first iteration of draw(), frameCount will equal 1.

finished

boolean finished

true if this applet has had it.

exitCalled

boolean exitCalled

true if exit() has been called so that things shut down once the main thread kicks off.

thread

java.lang.Thread thread

loadImageFormats

java.lang.String[] loadImageFormats

requestImageMax

int requestImageMax

By trial and error, four image loading threads seem to work best when loading images from online. This is consistent with the number of open connections that web browsers will maintain. The variable is made public (however no accessor has been added since it's esoteric) if you really want to have control over the value used. For instance, when loading local files, it might be better to only have a single thread (or two) loading images so that you're disk isn't simply jumping around.
