Hi,
I'm searching to make a function who has 3 parameters : String, ArrayList, Class ;

the goal of it is to search inside the ArrayList if an instance has the name specified in String parameter.

I've got an error : the Class parameter don't replace the Class name inside the function.

thanks a lot.
1. IntDict isNAMEinsideCLASS(String name, ArrayList itemList, Class theClass) {
2. IntDict toReturn = new IntDict();
3. int nmbInequality = 0;
4. for (int i= 0; i<itemList.size(); i++) {
5. theClass item = itemList.get(i);
6. if (item.name.equals(name)) {
7. toReturn.set("true", i);
8. }
9. else {
10. nmbInequality+=1;
11. }
12. }
13. if(nmbInequality == itemList.size()){
14. toReturn.set("false", -1);
15. }
16. return toReturn;
17. }

is there a way to expand an Array[][] ?
I manage to expand the second array acces with append() but I didn't manage with the first.

I also tried this, but it didn't work.
1. String[][]messOsc;
2. int step;
3. void setup() {
4. messOsc = new String[1][2] ;
5. step = 0 ;
7. messOsc[step][0] = "addr";
8. messOsc[step][1] = "value";
9. step+=1;
10. messOsc = expand(messOsc, step+1);
12. messOsc[step][0] = "addr2";
13. messOsc[step][1] = "value2";
14. etc..
15. }

how to make a full screen option

Hi,

is there a way currently to incorporate a full screen option in a sketch ?

- I saw that the library full screen is "semi-dead".

- I saw this wiki :

http://wiki.processing.org/w/Window_Size_and_Full_Screen

but *sketch>present* don't work on my machine (win7, processing 2.0.1) : it display the initial sketch at the center, and a piece of grey rectangne at the top left corner. idem with

                    
                     boolean sketchFullScreen() {
                      return true;
                     }

I try with :

size(displayWidth, displayHeight);

it give me a sketch at the dimension of my screen but i didn't manage to switch between 2 size e.g this don't work :

                    
                     void setup(){
                     size(400, 400);
                     background(0);
                     text("press a key to full screen", width/2, height/2);
                     }
                     

                     void draw(){
                     }
                     

                     void keyPressed(){
                      size(displayWidth, displayHeight);
                      background(0);
                      text("full screen on", width/2, height/2); 
                     }
                    
And like the purpose is for the web, I try to export with processing.js
 but its looks like the variable displayWidth  and displayHeight doesn't work. (I try to display them 
in a text(); ). 

idem with : **  size(displayWidth, displayHeight);** it don't give a big sketch. (tried with firefox & chrome).

thanks

limit loadStrings

Hi,
I'm trying to limit the length of an array loaded with loadStrings().
For best performance I have to analyze only the 20 first lines of documents (.pdf files) who have more than 7 thousands of lines.

I saw this topics so I try this :
1. InputStream is = createInput("theUrlOfMyPdfDocument");
  String line = null;
  try
  {
  BufferedReader reader = new BufferedReader(new java.io.InputStreamReader(is, "UTF-8"));
  while ( lines.size() < 20)
  {
  lines.add(line);
  }
  }
  catch (IOException e)
  {
  e.printStackTrace();
  }
  
  println(lines.size()); // print 20
  println(lines[0].get()); // don't work
  
  exit();
it looks OK, but after I don't manage to see and use the content of these first lines : I'm new with ArrayList...
thanks

verify if URLs of pdf documents are valids ?

Hi,
I'd like to verify if many URLs of PDF document are valids or not.
I try first with :
1. XML xml;
2. xml = importWML("myURL");
3. println(xml);
but it returns errors, becasue PDF isn't like XML data.

and I just discovered the createInput function :
1. InputStream input = createInput("http://www.theses.fr/2006PA083007/document");
2. println(input);
if the URL is ok it return " sun.net.www.protocol.http.HttpURLConnection$HttpInputStream@556917ee" else " null".
Do you think this is reliable ?
I mean if Processing return " sun.net.www.protocol.http.HttpURLConnection$HttpInputStream@ + numbers or letters" is that mean the link is valid ?

thanks

Hi,
I had to create new String who had the name an element of another String - imported with Open Sound Control :
for example I receive this message :
1. String inputOSC = "/in/vox/amp";
and I'd like to create a new String who has the name of the 2nd element of inputOSC (i.e. "vox").
1. // this don't work :
      String inputOSC = "/in/vox/amp";
      String[] splitInputOSC = splitTokens(inputOSC, "/");
      String splitInputOSC[1] = "myNewString";
I saw a similar question in the forum, and the response was the use of "HashMap" ?
thanks a lot

Hi,
I don't manage to export a text file with multiple lines. Each time the 1st line is rewritten :

void setup() {
String[] isbn = loadStrings("../listeIsbn.txt"); // *listeIsbn.txt* contain 3 lines

for(int i=0 ; i< isbn.length ; i++){
output = createWriter("export.txt") ; // only one line in the .txt export
output.println(isbn[i]) ;
output.flush();
output.close();
}
}

thanks
