  • Serial Library: Connect and disconnect
    I need to connect and disconnect the serial port while my draw() loop is running.
    I can connect once (in setup()) using:
    myPort =
    new Serial ( this , Serial.list()[0], 9600);
    And I can disconnect (in draw()) using:
    Serial(close);
    How can I re-connect again in draw()?
     
     
  • Processing 2.0b9: Open File
    When opening an existing sketch using the control button, the sketch is opened in a new window. In version 1.5.1 this would only happen if 'shift' was pressed during the process. Is this intentional?
  • Processing 2.0b9 External Editor
    The option for using an external editor has now been removed from the Preferences dialog.
    I modified the line: editor.external =true in preferences.txt and restarted Processing, but it was still possible to edit in Processing. Is this a known bug, or am I doing something wrong?
  • Text() query using char arrays
    In the following example, why does the character array 'abcd' print in a different location to the string "efgh"?
     
    size (100,100);
    textFont(createFont("Arial", 20));
    char[] c = {'a', 'b', 'c', 'd'};
    String d = "efgh";
    text(c, 0, 4, 40, 40);
    text(d, 0, 4, 40, 40);
