controlP5 - scrollList
Mar 5th, 2009, 11:56am  
hey,
i have some problems with scrollList.
I need to use letters "č","ž","š", but if i use them i get these exception:
Exception in thread "Animation Thread" java.lang.ArrayIndexOutOfBoundsException: 320
at controlP5.BitFontRenderer.getWidth(Unknown Source)
at controlP5.Label.<init>(Unknown Source)
at controlP5.Label.<init>(Unknown Source)
at controlP5.Controller.<init>(Unknown Source)
at controlP5.Button.<init>(Unknown Source)
at controlP5.ScrollList.addItem(Unknown Source)
and i know it is because these letters, coz otherwise - without them it works just fine. is there any chance to avoid exception and get scrollist to work as it should, no matter what letters am i useing?
tnx, kaja

I found your message incidentally when researching to answer the ControlP5_font size() question. See this thread for the gory details...
But in short, controlP5 uses custom bitmap fonts with limited character sets, and stops on low Ascii (char code 127) although it supports char width up to code 255 (but forgot the Unicode ranges!).

So in short you cannot use non-Ascii chars in controlP5.

So any ideas on how to convert unicode strings to ascii, so that they could be used?  I understand that it can't convert characters it doesn't understand, but I think it can place a "?" or something.

Code:
String unicode = "éçč ŕžošů";
try
{
  byte[] bytes = unicode.getBytes("LATIN1"); // US-ASCII for stricter conversion
  String ascii = new String(bytes);
  println(ascii);
}
catch (UnsupportedEncodingException uee)
{
}

Thanks, worked great!  I had tried something similar but had forgotten the "try" statement, which resulted in an UnsupportedEncodingException error.
