applet size (100x100) not code size
Apr 13th, 2010, 6:28pm  
Why would Processing build an index.html page that doesn't use the same size(width,height) parameters as those in the sketch code? I've got two students who've done this. Paste the code in a new sketch, runs fine. Export to web applet, runs in 100x100 window....

Suggestions?

the values in size() must be numbers, they can't be computed values or constants.

size(640, 480); // good
size(120 * 2, 240 * 2); // bad
size(WIDTH, HEIGHT); // bad

Ah!! Really hmm.... I guess that makes sense, given the need to construct index.html from the source code. THANK YOU!

Your students probably used Code:
size(screen.width, screen.height)
, which I use in many sketches. Its defaults to (100, 100)

I have a related question, applets in Firefox will not run at 100%, 100% after the index.html is changed from (100,100) After looking at it a while, I have realized that it is reading from
Code:

<!--[if !IE]> -->
<object classid="java:Senior_site_rect2.class" 
type="application/x-java-applet"
archive="Senior_site_rect2.jar"
width="100%" height="100%"

Which is the IE section of code. Changing these works in safari and chrome

Does anyone know how to make this work?

no, it's not. the comment above says "if !IE": if NOT InternetExplorer

and this

size(screen.width, screen.height)

is never going to work - it's the size() call that sets the screen.width and screen.height - so you're using the variables before they are set. so you get the defaults, 100x100.

Thanks for clearing up that ! means not. From my testing, only firefox uses the !IE section and safari/chrome/ie use the latter.

My question to you. Can I set a variable with javascript that reads the browser window size, and changes the width and height to the correct amount

I am a bit surprised... Will do my own tests! Smiley
First, you should specify what version of Processing you are talking.
Since Processing 1.1, deployment on browsers with JavaScript enabled is done via the Java deployment kit (deployJava.js). The conditional part is used only if JS is deactivated (but most people allowing Java to run also allows JS...).
